The heater of a cooling liquid automobile. How to install a coolant heater

Starting the engine "on the cold" - serioustest for any of his system. Cold start is several tens of kilometers in difficult conditions. Also, the driver and passengers of the car is not very comfortable. So, for all those who live in the cold areas of our country, we need not a leather interior and various options, but a coolant heater. Installing such a device can significantly extend the life of the power unit, save a decent amount of money on fuel, because the cold engine consumes much more.

coolant heater
These devices have become very common inthe armed forces. Almost on every military machine, heating boilers were installed, which, according to the principle of operation, as well as by their purpose, were very similar to heaters for coolant.

Advantages of these heaters

These gadgets got widespread because of its merits. Heater coolant has a simple device and is able to warm the coolant even in extreme cold. In addition, the device heats the coolant long before the engine is started.

Between the elements of the power unit and coolantthere is a uniform exchange of heat. Parts that work in the cylinder-piston group are not subject to wear during the cold start process. These devices provide a stable start even with very strong frosts.

Thanks to these heaters it is possible to significantlyreduce the load on the starter and other nodes that are involved in the launch. Significantly reduced fuel consumption. Heater coolant has other options: with it you can warm the interior or melt the ice on the windows of the machine.

Types of equipment

Distinguish fuel heaters, electrical and thermal. Consider each one of them.

electric coolant heater
Each group of equipment has its own characteristics and features. Any heater is multifunctional.

Fuel Preheater

So, fuel appliances are probably the most popular among car owners.

installation of a coolant heater
Their work is based on the energy that is formedin the process of burning fuel. The advantage of this group of heaters is full autonomy. The heater not only warms up the coolant, but also makes the temperature of the air inside the car comfortable. Among the most famous manufacturers are Webasto, Teplostar, Eberspacher.

How the fuel heater works

According to the principle of operation, this stove works ondiesel fuel or gasoline. A special pump pumps fuel from the tank into the combustion chamber, where the mixture with air is prepared. Then the mixture is ignited with a ceramic pin, which is heated by a small current.

Coolant heats up when passingthrough the heat exchanger. When it warms up to 30 degrees, the cabin ventilation starts. When the coolant heats up to 70 degrees, the car coolant heater will start working at half its power.

Many devices have a special summer mode. These devices are activated by various methods. So, a simple and affordable way is a timer that can be programmed. If the departure schedule is unstable, then remote control is provided by means of a remote control or a GSM module. For those who choose autonomy, this is a great choice.

Electric heaters

Electric Coolant Heateralso popular with car owners. The device is operated using alternating current from external networks. Often, the equipment is connected to the network of 220 V. But the equipment starts to enter the market from 12 V. It is more economical. Such 12-volt devices can be more often found in northern Europe than in our country. The advantage is that a 220 V coolant heater does not release any harmful substances into the atmosphere. Electric current is completely harmless.

These devices are noiseless, distinguished by affordablecost and have a high heating rate. The device is somewhat reminiscent of boilers from the outlet. Connects such a device either in the cylinder block or in the car cooling system connections. This group of equipment performs three functions - it heats the coolant, heats the air inside the car, charges the battery. In general, work from 220 V is a feature of these devices. Among well-known manufacturers - Defa and domestic companies "Leader", "Severs". The same can be said about the 12V coolant heater. However, it does not charge the battery, and the device can be powered from the cigarette lighter.

Principle of operation

The principle of operation of these devices is similar to the work of the boiler.

220 coolant heater
Believed to create true comfortbasic kit may not be enough. So, it is necessary to purchase an additional separate module with a fan for heating the passenger compartment. You also need a device to charge the battery if the device is used under 12 V.

If not always convenient to turn on and offheating system in the cold, it is possible to complete the heater with a remote control or a timer. But the price of this kit will differ significantly from the base. Among the available models, you can select the Severs-M coolant heater - almost the equivalent of the Norwegian Defa. This is an excellent choice that does not depend on the battery charge level, does not consume fuel, has an affordable price in the basic configuration.

Heat accumulator

Finally, the last type - heat heaters,or batteries. They are also marketed quite recently. They are very effective, but not very popular. As well as electrical equipment, this coolant heater is powered by 220 V. However, its function is not to heat the coolant, but to keep it already heated. The device performs several functions. So, thermal energy is stored, stored, used for heating.

How it works?

This is a thermos. It contains liquid in the same volume as in the cooling system of the car. While the engine is running, the fluid in the tank is constantly changing and thus maintains a constant supply of hot coolant. Before the engine is started, through the operation of the pump, the cold antifreeze changes places with hot. In just 15 seconds, a hot coolant will appear in the cooling system of the car.

The main thing when working with these systems is regularcar operation. Under conditions of Moscow winters, warm antifreeze can keep the temperature up to three days, but in severe frost it is recommended to store hot liquid every day.

Coolant Heater DIY

If buying a branded device is expensivepleasure, then there are schemes with which you can do the same thing yourself. It will be an electrical device. There are many different options. For a heating element, you can take a small piece of pipe with a wall thickness of 0.8 mm, nozzles of sizes 20 mm, metal in sheets, a nichrome spiral, and a pump from GAZelle.

At first, the pipe is sawed off. The length of the segment should be about 80 mm.

12v coolant heater
From metal with a thickness of 1 mm, it is necessary to cut the plates according to the internal diameter of the tube. Just cut two more plates.

The whole difficulty is in makingheat exchanger. It is recommended to do with a welding machine. You can also just solder. Asbestos sheets can be used for insulation. It is embedded in the heat exchanger on both sides.

The spiral is cut so that its resistanceranged from 2.5 to 4 ohms. The less resistance, the more it will warm up, but there is a risk of overheating. Two discs with a diameter of 80 m are cut out of the paronite, on which the helix is ​​fixed.

do-it-yourself coolant heater
It is also necessary to make a body of metal. These may be covers. Heating elements are inserted inside the pipe. Lay them need to spiral down. Next, the heaters are laid with asbestos, install covers. To increase thermal insulation, the entire structure turns into a peneplain. Here is the heater and ready. It is powered from a network of 12 V.

Installing a coolant heater

The installation process is simple, but will take time. For installation, you must prepare the clamps, tees for branching, bracket, spring and the device itself. Installation should be carried out in a place where the coolant can easily flow directly into the tee and top of the system. That is, it is best to install the device under the hood on the left.

The part must be installed as low as possible, but not lower than the engine protection.

Next, inside the device is poured slurry. Antifreeze from the system merges. A bracket is put on the device, a branch pipe is inserted into the hole and tightened with a clamp. Next, the drain plug is removed, the pipe is pulled up to it and the fitting is put on, which is then screwed together with the plug.

The short pipe is removed and divided in two. Tee grease sealant and wear connections. Then all this is tightened with clamps, a thick pipe is screwed back. Now everything is ready, you can pour antifreeze and use the device.
