Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning evaporators, in particular to an air-conditioning evaporator with a water filtering device. Background Art

[0002] The refrigerant of the air conditioner enters the evaporator from the expansion valve or the throttle tube. Due to the sudden expansion of the refrigerant volume, it becomes a low-temperature, low-pressure mist-like particle liquid. The refrigerant in this state is very easy to vaporize, and it will absorb a large amount of heat from the surrounding when vaporizing. The air conditioning fan forces the air entering the car to flow through the surface of the evaporator, and transfers the heat to the refrigerant in the evaporator through the tube sheet, and vaporizes the liquid refrigerant by absorbing heat.

[0003] After searching, the application with patent number CN202222799320.0 discloses an air conditioner evaporator, including an evaporator body, the evaporator body includes a bracket, the number of the brackets is 2, a copper tube is bent and fixedly installed between the two brackets, and heat dissipation fins are equidistantly fixedly installed between the two brackets;

[0004] Although the air-conditioning evaporator can protect the heat dissipation fins by driving the partition plate through the horizontal plate, the air-conditioning evaporator is not convenient for replacing the copper tube. When a copper tube is damaged somewhere, the evaporator needs to be replaced as a whole, which results in high cost.

[0005] Therefore, we propose an air conditioner evaporator with a water filtering device. Utility Model Content

[0010] Preferably, the infusion tube is spiral-shaped, and a heat dissipation strip matching its contour is fixedly installed on the outer surface of the infusion tube, and evenly distributed heat dissipation fins are fixedly installed on the top surface of the liquid inlet box and the bottom surface of the liquid discharge box. Among them, by setting the infusion tube to a spiral shape, the contact area between the infusion tube and the external air can be increased, thereby improving the effect of heat exchange of the refrigerant inside the infusion tube. The contact area between the infusion tube, the liquid inlet box and the liquid discharge box and the external air can be increased by the heat dissipation strips and the heat dissipation fins, thereby improving the heat exchange efficiency between the liquid inlet box, the liquid discharge box and the infusion tube and the external air.
