Honda radiator fans are installed on the car at home, which is a device to help the air conditioner in the car to cool down. Do you guys want to know how the Honda radiator fan works? It is a small series today to introduce you to the car Honda radiator fan installed, then everyone with Xiaobian to understand it.
Honda radiator fan working principle introduction: Introduction
It is based on water temperature, engine load, signal transmission to the computer, engine computer control fan high and low speed relay, and also affected by air conditioning pressure, the principle is this, air conditioning computer receives air conditioning pressure switch, indoor and outdoor temperature, and other signals, and then through the bus The air conditioning signal is transmitted to the engine computer. The engine receives the signal that can be turned on, controls the compressor, and controls the fan relay to pull in. When the air conditioner pressure is affected by the environment and its own influence increases, the engine computer receives the air conditioner computer signal and controls the fan high speed relay. Pull in and the fan runs at high speed.
How Honda Radiator Fan Works - Simply
The heat sink works on heat transfer.
The principle of the cooling fan is to increase the air circulation of the heating software, and to continuously remove the heat through the continuous circulation of the air.
In fact, all have heat transfer. The high temperature is transmitted to the low temperature.
If the car's cooling fan does not turn, it will cause the cooling temperature in the engine water tank to be too high, which is very dangerous. It must be stopped and repaired immediately. The following small series will explain to you the solution that the car cooling fan does not turn.
Today's car Honda radiator fans mostly use electronic temperature control to work, the temperature of the water reaches the required temperature, the fan will start to rotate normally.
If the water temperature meets the requirements and the cooling fan does not turn, then there may be a problem with the fan relay.
If there is no problem in the above two aspects, you can check the temperature control switch. The failure of the temperature control switch will also have a certain impact on the operation of the Honda radiator fan.
