PTC heaters are made up of specialized heating discs with sophisticated ceramic materials with a positive temperature coefficient. These heaters are safe, powerful, and energy-efficient, allowing for excellent heat production and transfer even in the tiniest of areas. 

Fin elements and honeycomb shapes are the two types of PTC heaters. While both types of heaters have several advantages over traditional heaters, users should be informed of the advantages and disadvantages of each before choosing one.

What is a PTC Heater, and how does it work? 

Traditional resistance wires and coils are used to create heat in most ordinary heaters. This is not the case with a PTC heater. 

Instead, it uses ceramic stones made of barium titanate as heating components. The PTC heater can operate as a sensor because of the material’s unique features. Without the use of additional diagnostic or feedback controls, the heater can operate in an open-loop mode. As a result, there is no risk of overheating with a PTC heater. It’s also much more efficient and trustworthy than the regular model, making it perfect for products that need to be heated safely, quickly, and uniformly.

What Can a PTC Heater Do for Your Next Project?

Now that we’ve learned a little more about PTC heaters let’s look at how they may help you with your next industrial project. 

1. Improved Heating Functionality

We’ll start with one of the greatest benefits of PTC heaters. They enable users to generate the same amount of heat as a normal model while posing a fraction of the safety danger. 

PTC heaters from Narain Cooling have a unique design that avoids all of the failure modes and hazards common with resistive wire, carbon fiber, and etched foil heaters. If a problem occurs, the system will “fail to cold” to make the effect unnoticeable. The heater component that failed will no longer take any extra current, while the rest of the heater will continue to operate normally. 

2. Self-Limiting Characteristics

Because of its self-regulating properties, when the resistance of a PTC heater increases, the current within the device drops, the heater can sense the temperature around it and turn off if it rises above its specified setting. 

This built-in safety and security function ensures that you’re not creating too much or too little heat for your project’s requirements.

3. Self-Regulating Characteristics

A PTC heater is also self-regulating and self-controlling.

A PTC heater modifies its usage in response to changes in the environment. When it reaches an ideal temperature, it can slow down production over time. The heater can keep its lowest output and maintain its temperature when it turns off. 

4. Complex Heating Patterns

Narain Cooling Engineers can create a PTC heater to meet specific heating solutions as detailed as required, as indicated above.

You may set your temperature zones exactly where you want them to ensure maximum coverage while constructing your units. You can also alter the watt density and create custom holes and cuts as needed with simple tweaks. 

This user control ensures that heat is distributed evenly and consistently. Every point on the surface of a PTC heater maintains its fixed temperature independently, eliminating hot and cold areas. 

5. There are fewer components to deal with

A PTC heater has fewer working components than a traditional radiator. There will be less wear and tear to contend with, as well as fewer expensive components to replace. Additionally, your system’s ceramic components are less sensitive to water, chemical abrasion, and corrosion. These advantages boost your investment’s return and ensure that your control system lasts as long as feasible. 

The few parts that make up a PTC heater only turn on when they’re needed, rather than maintaining high temperatures all the time. This feature contributes to the parts’ long-term durability and stability. It doesn’t take long for high temperatures to wear down materials when they are applied at a continuous rate. 

6. Cost-Effective Compared to Traditional Models

PTC Heating is a smart and straightforward way to heat your home. 

In the long term, this means less energy consumption, saving users a lot of money. 

PTC heaters are designed to use full power at lower temperatures, allowing them to reach their threshold temperature as quickly as possible. They use less energy than typical heaters after they reach a constant state. When you pick PTC heaters, you can save money on a variety of things in addition to your utility bills. The lesser number of parts on a PTC heater, for example, helps to reduce maintenance and upkeep costs. 

7. Materials that are compact and lightweight

Forget about those clumsy old heaters. When you buy a PTC heater from Narain Cooling, you get a small system and light. The footprint of the PTC unit should be as compact as possible. 

Silicone heaters are less flexible than PTC heaters. You can even connect additional PTC heaters in parallel to meet the heating needs of a very wide area. 

These materials aren’t very bulky, but they’re far from inconsequential. They’re the backbone of PTC heating technology, both innovative and efficient. Creating them, on the other hand, has no negative impact on the environment.

Today, we’ll talk about your vehicle’s cooling system and how it works. Your vehicle’s cooling system consists of the water pump, radiator, cooling fans, and thermostat. We’ll talk about radiators and different types of radiators in this post.

What is The Radiator, and what does it do?

Radiators are heat exchangers that allow thermal energy to be transferred from one medium to another for cooling and heating.

A radiator is a cooling device with a wide cooling surface and a big volume of air that distributes through the water to efficiently cool it.

Radiators are used to cool the internal combustion engine in automobiles and have a wide range of uses in the automotive industry. They’re also utilised in piston-engined aeroplanes, railway locomotives, motorbikes, stationary generating plants, and other applications.

The direction of water flow through radiators is used to classify them. Some radiators have a top-to-bottom flow, whereas others have a top-to-bottom flow. In a cross flow type radiator, water flows horizontally from one input tank on one side to another tank on the other side.

Because of their great heat conductivity, copper and brass are commonly used in radiators. Soldering connects the various components of the radiators almost entirely.

Radiator Types

Radiators are divided into two categories.

• Tubular type
• Cellular type

Core of Tubular Type

The top and lower tanks are connected by a network of tubes through which water travels in a tubular type core. To enhance heat transfer, fins are put around the tubes. As air travels around the exterior of the tubes and between the fins, it absorbs heat from the water.

Because water flows through all of the tubes of a tubular radiator, if one becomes blocked, the entire tube loses its cooling function. The blockage of any channel in a cellular radiator results in a loss of just a tiny portion of the overall cooling surface.

Core of Cellular Type

Air travels through the tubes and water flows through the gaps between them in a cellular type core.

The core is made up of a huge number of separate air cells that are encased in water. The cellular type is sometimes referred to as a honeycomb radiator because to its look, particularly when the cells in front are hexagonal in shape.

The blockage of any channel in a cellular radiator results in a loss of just a tiny portion of the overall cooling surface.

Is it Possible to Drive a Car Without a Radiator?

You can start your automobile without a radiator, but it’s a dangerous proposition. As long as the engine does not overheat, you will not do any damage. It’s not an issue if you don’t run it long enough for the engine to become too hot. If your automobile overheats, you must turn it off and allow it to cool down by convection.

Radiators are, in theory, entirely optional on an engine. Air-cooled engines have been around for quite some time. Cooling fins on these radiators remove heat and release it into the air.

But,

However, if your automobile was built with a radiator in mind, you’ll need one. There is no need to get rid of it.

What Makes an Engine Overheat?

An inadequate amount of water in the cooling system causes overheating. Clogged radiators and water passageways, belt slippage, demanding thermostat, late ignition timing, improper valve timing, pre-ignition, too tight bearing, low engine oil level, clogged exhaust system, and other factors can all contribute to this.

What Are the Symptoms of a Faulty Radiator?

• When the coolant can’t get to where it needs to go to cool the engine, it warms up.
• The hoses may be blocked, or the coolant level may be too low.
• A warning light may appear on the dashboard, or the temperature gauge may indicate that it is excessively hot.
• You may detect the scent of antifreeze or a tell-tale puddle on the garage floor if a hose is damaged or the radiator is rusted with rust.
• If you notice smoke coming from beneath the hood, it’s possible that coolant has leaked onto the engine and is being burned up.
• If you notice smoke escaping from the muffler, it’s possible that the head gasket has been damaged by the heated engine.

PTC heaters are made up of specialised heating discs made of sophisticated ceramic materials with a positive temperature coefficient. These heaters are safe, powerful, and energy-efficient, allowing for excellent heat production and transfer even in the tiniest of areas.

Have you ever had your heater break down just when you needed it the most? Have you ever heard of hot spots or overheating in vehicle seats? We’ve been relying on fixed resistance heaters for the majority of our demands for decades. When a single point sensor ‘assumes’ the temperature of the entire heater, safety is still an issue. 

Despite the numerous problems that traditional heaters have faced, we continue to use them broadly throughout industries. Narain Cooling, on the other hand, now has the solution to all of these problems: PTC heating, a technology that prioritises safety.

What are PTC heaters?

PTC heaters are self-regulating heaters that operate in an open loop without the use of external diagnostic controls. PTC heaters use conductive inks printed on thin, flexible polymer-based substrates to generate heat, rather than the wires and coils used in classic fixed-resistance heaters. 

They are perfect for goods that demand safer, faster, and more uniform heating due to their great dependability and efficiency. Because of the material’s characteristics, the PTC heater can function as its own sensor, obviating the requirement for external feedback controls. As a result, there is no chance of overheating with the heater.

What is a positive temperature coefficient?

When a material has a positive temperature coefficient, it means that as its temperature rises, so does its resistance to current. When the design temperature is reached, the current through these devices rises sharply because to the low resistance, but subsequently drops to zero. These gadgets are made to reach a certain temperature throughout the manufacturing process.

Types of PTC heaters

Fin elements and honeycomb shapes are the two types of PTC heaters. While both types of heaters have a number of advantages over traditional heaters, users should be informed of the advantages and disadvantages of each before choosing one.

The power consumed by PTC heaters

PTC heaters use all of its available power to quickly heat up and reach the desired temperature. As the temperature rises, the power consumption decreases. This dynamic heating system is not only efficient in terms of time and energy, but also in terms of effectiveness. 

PTC heaters may work at temperatures ranging from -40°C to 70°C (-40°F to 158°F). During the design process, the threshold temperature is modified. Heaters with different temperature zones are possible, and the watt density can be adjusted with a few easy changes.

What do PTC heaters offer?

Conductive inks are genuinely authoring the success tale of printed electronics, such as PTC heaters, with a remarkable blend of performance and usefulness. They provide you the ability to create complex heating schemes. They’re also abrasion-resistant, cost-effective, and simple to manufacture in big quantities. Carbon conductive inks are screen printed on polymer-based substrates using PTC heaters. While polyester is the most common substrate material, other materials can also be employed. The PTC conductive inks can withstand several heating and cooling cycles. To avoid moisture infiltration and mechanical wear, the printed circuits are sealed with an adhesive laminate.

How are PTC heaters unique?

Heaters made with PTC cannot overheat. When the resistance of the device increases, the current through it lowers, making the gadget self-limiting. They can also be described as self-restraint. When the ambient temperature drops, the heater’s resistance drops, drawing more current and counteracting the cooling trend. Any tendency to raise its temperature, on the other hand, has the opposite effect. These qualities are not present in convection heaters.

The Point of Curie

PTC ceramics can be made with a variety of predetermined temperatures at which this drastic resistance shift occurs. The Curie point of the PTC heater is the temperature at which this happens.

More adaptability In the manufacturing industry

PTC heaters can be configured to function at temperatures ranging from -40 degrees Fahrenheit to 158 degrees Fahrenheit, making them ideal for a wide range of equipment design applications. The material utilised can be made in an infinite number of shapes and sizes. For specific uses, custom shapes can be created. Machined, drilled, bent, and curved PTC materials are all possible.

What are the advantages of PTC technology?

PTC Technology has considerable advantages in two critical areas, making it ideally suited and safe for use in the bilge region of your yacht. The first and most important consideration is safety. PTC heaters are self-limiting, which means that as they approach their design operating temperature, they automatically reduce their power consumption. Overheating is impossible with PTC heaters.

The maximum output level of the Xtreme Heater PTC element is chosen to offer enough heating power to maintain above-freezing temperatures within the engine compartment at low ambient temperatures.

Conclusion 

The PTC element powers down to a minimum operating level without overheating; it stays operational as a convection heater to prevent freeze damage. When the heating system is suddenly subjected to a thermal load caused by lowering ambient temperatures or a consumer-induced event, such as opening the engine compartment hatch and allowing cold air in, the PTC heater from Narain Cooling will instantly raise its heating power to compensate for the heat loss. As soon as this is completed, the heater will return to treading water mode and stabilise at a reduced power level.
