AI Technical Summary

Technical Problem

The heat generated by the scroll fixed plate and scroll moving plate inside the front cover of the existing split-type automotive air conditioning compressor cannot be effectively and quickly dissipated, resulting in reduced compressor efficiency and even possible burnout.

Method used

The front cover is equipped with an air intake pipe, a support plate, a first disc, and a second disc with a heat exchange ring. Heat is conducted through the air intake pipe and the support plate, and rapid heat dissipation is achieved through the heat exchange ring. The limiting structure ensures stability and sealing.

Benefits of technology

It enables rapid heat dissipation within the front cover, maintaining a lower temperature, improving the compressor's operational stability and efficiency, and preventing damage caused by high temperatures.

Abstract

A first disc body is arranged at the lower end of an air suction pipe, a plurality of supporting pieces are arranged on the first disc body in an array mode, the first disc body abuts against the top of a vortex fixed disc, the tops of the supporting pieces abut against the top in a front cover, a second disc body is further fixed to the top of the front cover, and the second disc body abuts against the top in the front cover. A plurality of circles of heat exchange rings are arranged on the second disc body, a hollow pipe is further arranged in the middle of the second disc body, the upper end of the air suction pipe sequentially penetrates out of the front cover and the hollow pipe, and the outer wall of the air suction pipe abuts against the inner wall of the hollow pipe. Heat generated when the vortex fixed disc and the vortex movable disc work is rapidly guided to the front cover through the first disc body, the supporting pieces and the air suction pipe, the second disc body with the heat exchange ring is arranged on the front cover, the second disc body rapidly exchanges heat with the front cover and the air suction pipe, and therefore the temperature in the front cover can be kept low.
