Description

Technical Field

[0001] The utility model relates to the technical field of automobile evaporators, and more specifically to an automobile evaporator core. Background Art

[0002] The evaporator is one of the components of the automobile air-conditioning system. It is the place where the refrigerant in the air-conditioning system changes from liquid to gas, that is, evaporates and absorbs heat. It can make the refrigerant change from liquid to gas (i.e. evaporate), absorb a large amount of surrounding heat, improve the driver's comfort, reduce fatigue intensity, and improve driving safety. The function of the evaporator is to evaporate the low-pressure refrigerant coming out of the expansion valve and absorb the heat of the air in the car, so as to achieve the purpose of cooling the car. The evaporator is divided into tube-sheet type, tube-belt type and cascade type. At present, cars mainly use all-aluminum cascade and tube-belt evaporators, large buses mainly use copper tube aluminum sheet evaporators, and medium-sized buses have several types, mainly tube-belt type.

[0003] The evaporator is the core component of the car's air-conditioning system. After the air-conditioning evaporator on the car has been left for a long time, a large amount of dust and residue will accumulate on the surface of the equipment. If it is not cleaned, the air-conditioning heat exchange capacity will decrease. Moreover, when the car is driving on a rough road, the car evaporator core will become loose or damaged due to body vibration and other reasons, which will cause the evaporator to not work properly, causing the air-conditioning system inside the car to shut down, affecting the user experience.
