Description

Technical Field

[0001] The utility model belongs to the field of automobile air conditioners, and in particular relates to a high-strength shell structure suitable for an evaporator. Background Art

[0002] As one of the important parts of a car, the car air conditioner can effectively improve the comfort of the car, thereby improving the experience of the car owner and passengers. Car air conditioners are usually composed of a compressor, an evaporator and a condenser. The evaporator is used to exchange heat with the air in the car to achieve a cooling effect. In order for the car air conditioner to achieve a rapid cooling effect, it is necessary to increase the contact area between the evaporator and the air in the car to speed up the heat exchange efficiency of the evaporator. However, increasing the contact area between the evaporator and the air in the car means increasing the installation cavity of the evaporator. The increase in the strength of the installation cavity will reduce, which will lead to a reduction in the service life of the installation cavity. In order to increase the service life of the installation cavity, the cavity wall of the installation cavity is usually thickened, which in turn increases the weight of the installation cavity and makes installation difficult.

[0003] In the prior art, for example, the patent document with publication number CN215638143U discloses a high-efficiency evaporator, including an outer shell, a positioning plate and an evaporation tube, wherein the evaporation tubes are installed at equal distances at both ends of the outer shell through PP limit blocks and sleeves are sleeved on the outside of the evaporation tubes, and the sleeves and both ends of the evaporation tubes penetrate the outer shell and are located at the two ends of the outer shell. The evaporator increases the contact area between the evaporator and the air by equidistantly arranging the evaporation tubes, thereby improving the heat exchange efficiency of the evaporator; however, it also makes the shell of the evaporator thicker, increasing the difficulty of installing the evaporator.

[0004] Therefore, there is an urgent need for a high-strength shell structure suitable for an evaporator to solve the above problems. Summary of the invention
