Description

Technical Field

[0001] The utility model relates to the technical field of vehicle evaporators, in particular to an evaporator with an air suction structure. Background Art

[0002] The principle of a vehicle evaporator is to lower the air temperature by absorbing heat through the evaporation of liquid refrigerant. It is a key component in a vehicle's air conditioning and refrigeration system, primarily evaporating the low-temperature, low-pressure liquid refrigerant from the expansion valve into a gaseous state. This process is an endothermic reaction, which absorbs heat from the evaporator and the surrounding air, thereby lowering the air temperature and achieving a cooling effect. After searching, the prior art (Announcement No.: CN202022352571.5) is a vehicle evaporator with high heat dissipation efficiency. The article records that "when the evaporator body needs to be cooled and cooled, the water pump and the cooling fan are started, and the cooling fan generates cooling air. The water pump draws cooling water from the water tank and pumps the cooling water to the water cooling pipe. Finally, it returns to the water tank, and the air inlet and exhaust holes realize the cooling air circulation. When the cooling air flows to the water cooling pipe, heat exchange occurs with the water cooling pipe, and the cooling air further cools down, thereby improving the heat dissipation efficiency of the evaporator body". However, in the prior art, the cooling air generated by the cooling fan is difficult to be evenly delivered to the vehicle evaporator, resulting in the problem of poor local heat dissipation of the evaporator.

[0019] Reference Figures 1 to 4 As shown, the utility model provides an evaporator with an air suction structure, comprising: a vehicle evaporator body 1, a heat sink 11 is mounted on the surface of the vehicle evaporator body 1,

[0020] The front and rear sides of the vehicle evaporator body 1 are symmetrically fixed with wind guide plates 2, the front surface of the wind guide plate 2 is welded with an air expansion plate 31, a cooling fan 3 is installed in the middle of the front end of the air expansion plate 31, and the inner side of the wind guide plate 2 is welded with a curved exhaust hood 4, and the side end face of the curved exhaust hood 4 is provided with an air outlet mesh port 41, and the inner side of the curved exhaust hood 4 is connected to the air guide cavity 33 of the air expansion plate 31 through the exhaust cavity 42.

[0021] The vehicle evaporator body 1 draws the outside air into the inner cavity of the air expansion cover plate 31 through the cooling fan 3 on the surface of the air guide cover plate 2. The air drawn into the cavity of the air expansion cover plate 31 is diverted into the arc-shaped exhaust cover 4, so that the arc-shaped exhaust cover 4 discharges the air to the distance between the heat sinks 11 of the evaporator, thereby accelerating the air circulation speed between the heat sinks 11 of the evaporator, facilitating more uniform ventilation and heat dissipation of the evaporator heat dissipation surface, avoiding local heat accumulation in the evaporator, and improving the heat dissipation efficiency of the vehicle evaporator.

The upper and lower ends of the air deflector plate 2 are connected to the side panels of the vehicle evaporator body 1 via fastening studs 22.

A temperature sensor can be installed on the inner side of the air deflector plate 2 to control the start and stop of the cooling fan 3 based on temperature increases.

The diverter block 32 facilitates the dispersion of the air sucked in by the cooling fan 3 to the left and right sides.

[0028] In this embodiment, the air guide plate 2 , the cooling fan 3 , the air diffuser plate 31 , the arc-shaped exhaust cover 4 and the air outlet mesh 41 constitute a distributed air suction and heat dissipation structure of the vehicle evaporator body 1 .
