Evaporation box blower motor principle.
The principle of automobile blower mainly involves the following aspects:
Function: The main function of the blower is to blow the cold air above the evaporation box of the air conditioner or the hot air of the warm water tank to the car, to achieve the air supply function. It rotates at a high speed, transmits the cold air from the evaporation box to the carriage, to achieve cooling or other temperature regulation purposes. The air from all air conditioning outlets in the car is blown in by the blower.
Composition: blower is mainly composed of motor, air filter, blower body, air chamber, base ( and fuel tank) , drip nozzle and other six parts.
Control principle:
Automatic control: When you press the "automatic" switch of the air conditioner control board, the air conditioner computer automatically adjusts the speed of the blower according to the required air temperature. Especially during the low-speed control period, the air conditioning computer makes the blower motor run at low speed by disconnecting the base voltage of the power triode .
Cycle mode: if the external cycle mode is selected, will enter the natural wind outside the car, temperature is slightly higher than outside the car; The internal circulation mode blows out the temperature inside the car. If high temperature is selected, is used to heat the cooling water of the engine through the evaporator in the air conditioning system, wind temperature is adjusted by the opening Angle of the natural wind partition.
Impact: If there is a problem with the blower, , such as abnormal noise or squeak, may affect the normal use of the air conditioner. , for example, if the blower is broken, the air conditioner may not discharge cold air properly, may cause the evaporation box to freeze, in severe cases may cause the pipe to burst. , therefore, blower is an important part of the automobile air conditioning system, its normal operation is very important to ensure the effectiveness of the air conditioning system.
In summary, automobile blower, through its design and control principle, can effectively send the cold air or hot air generated by the air conditioning system to the car, at the same time, through the choice of automatic control and circulation mode, provides comfortable temperature regulation function.
How the blower is connected to the evaporation box
First, direct connection mode
Direct connection means that the blower and the evaporation box are directly connected together. This connection is suitable for situations where the evaporation box and the blower are located close to each other and need to be dried quickly. When connecting, the air inlet of the blower should be aligned with the air outlet of the evaporation box, and then fixed through the pipe connection. This allows the air volume of the blower to be transferred directly to the evaporation box, allowing moisture to be discharged more quickly.
Second, indirect connection mode
Indirect connection means that the blower and the evaporation box are connected together through the pipe. This connection method is suitable for the evaporation box and the blower is far away, or the need for cooling treatment. When connecting, it is necessary to design a suitable pipeline according to the actual situation, so that the air volume of the blower can flow smoothly into the evaporation box. At the same time, pay attention to the selection of appropriate pipeline materials and seals to ensure the stability and sealing of the connection.
Note:
1. Pay attention to the wind direction of the blower and evaporation box when connecting to ensure that the wind can flow to the required direction.
2. The pipe connection should be kept flat and not bent too much, so as not to affect the air volume and drying effect.
3. When selecting pipeline materials, it is necessary to consider their high temperature resistance, corrosion resistance and other properties, as well as easy cleaning and maintenance.
4. When used, dust and debris in the blower and evaporation box should be cleaned in time to avoid affecting the drying effect and service life.
In short, the connection method of the blower and the evaporation box should be selected according to the actual situation and needs, and attention should be paid to the stability and sealing of the connection to ensure the drying effect and safety.
