Principle of diesel air heater for vehicle

Principle of diesel air heater for vehicle: Air heater is mainly composed of air heater and fan. The air heater radiates heat, which is then sent out by the fan, thus adjusting the indoor air temperature. The air heater consists of spiral finned tubes.

For example, the radiation exhaust pipe of a steam heater is wound on a seamless boiler tube with a wall thickness of φ 2 1.5 at a distance of 2.5 mm, and the exhaust pipe is integrally welded with the heat medium circulation pipeline, and the working pressure of the heater is below 0.8MPa.

Diesel heater, also known as fuel heater, is mainly suitable for industry and is an indispensable heating equipment for industrial heating. Microcomputer and PID temperature control, high uniformity, no washing temperature, energy saving, high quality stainless steel and steel plate for inner tank.

Matters needing attention of diesel heater for extended data vehicle

The warm air of the car is blown into the cab by the blower. If the air volume is not enough or the distribution of cold and hot air is not good, the heat of the warm air tank will not be emitted, and the temperature of the warm air will not come up.

At this time, first check whether the filter element is dirty and blocked, clean it, and replace it in time if necessary; Then check the operation of each gear of the blower, and each gear must reach sufficient speed.

If the knob is set to the warm air position, the air volume is large enough and the wind direction is normal, and the cold air is blown out, check whether the cable of the hot and cold air control flap in the warm air box falls off, whether the warm air impeller is damaged, whether the flap falls off, etc. After troubleshooting, the warm air will get hot.
