DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] The present application provides a rear cover structure of an automobile air conditioner compressor, as shown in Figures 1-5 The rear cover structure of the automobile air conditioner compressor comprises a machine body 1, and the machine body 1 is provided with a heat dissipation assembly at the end.

[0028] The heat dissipation assembly comprises a rear cover body 2 slidingly sleeved at the end of the machine body 1, a fixed plate 3 fixedly connected to the inner wall of the rear cover body 2, a plurality of heat conduction rods 4 fixedly connected to the inner wall of the fixed plate 3, and a heat conduction plate 5 fixedly connected to the inner wall of the rear cover body 2 on one side of the fixed plate 3, wherein the heat conduction plate 5 and the fixed plate 3 jointly form a filling cavity 6.

[0029] The end of the heat conduction plate 5 is provided with a plurality of mounting grooves 7, and a plurality of heat dissipation fins 8 for heat dissipation are fixedly connected in the mounting grooves 7.

[0030] The inner wall of the rear cover body 2 is threadedly connected with a heat dissipation plate 9 on one side of the heat conduction plate 5, and the end of the heat dissipation plate 9 is provided with a plurality of heat dissipation holes for facilitating air circulation.

[0031] Specifically, the heat dissipation assembly arranged in the rear cover body 2 can greatly improve the heat dissipation effect of the rear cover, the fixed plate 3 can conduct the working heat in the compressor and improve the stability of the rear cover body 2, so that the rear cover body 2 does not shake during the operation of the vehicle, the plurality of heat-conducting rods 4 in the inner wall of the fixed plate 3 can conduct the heat in the compressor, the filling cavity 6 formed by the heat-conducting plate 5 and the fixed plate 3 can divide the internal space of the rear cover body 2, concentrate and absorb heat, and release heat, avoiding the instability of the traditional method of relying on the natural temperature of the external environment to cool the compressor. Since the filling cavity 6 is filled with cooling oil, the heat can be stably conducted, and when the heat is in the cooling oil, the heat in the cooling oil can be dissipated through the heat dissipation fins 8. Since a plurality of heat dissipation fins 8 are arranged, the heat can be released more uniformly. Through the arrangement of the heat dissipation plate 9 and the heat dissipation hole, the temperature difference between the inside and outside of the cover body can be used to dissipate heat, improve the heat dissipation effect, and the component structure is simple and practical, economical, and avoids the instability of the graphene coating. The service life of the compressor is improved, and the maintenance cost is reduced.

[0035] Specifically, a plurality of threaded grooves 10 are arranged on the outer wall of the rear cover body 2, which can be connected with the machine body 1 through threaded connection. Compared with the clamping mode, the threaded connection has high stability and will not cause the parts in the rear cover body 2 to shake due to the bumping of the vehicle, which affects the heat dissipation effect of the compressor. By arranging the sealing groove 12 at the end of the machine body 1, a sealing ring can be arranged therein to improve the airtightness of the machine body 1 and reduce the damage caused by dust or water vapor entering the machine body 1. The mounting holes 13 can be used to facilitate the fixed connection with the vehicle installation position and improve the stability of the compressor. After installation, cooling oil can be poured through the oil inlet 14, and the threaded plugging plug can prevent the cooling oil from leaking due to the bumping of the vehicle and prevent external pollution from affecting the working effect of the cooling oil.
