Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration equipment, and in particular to the structure of a refrigeration compressor. Background Technology
[0002] The compressor of an ammonia refrigeration unit generates a lot of heat during operation. This waste heat causes the compressor to operate at high temperatures for a long time, resulting in a large amount of lubricating oil evaporating inside the compressor, which affects the overall lifespan of the refrigeration unit and the system's energy efficiency ratio.
[0003] Traditional compressor housings are mostly made of metal materials, such as steel and aluminum. Although these materials have good mechanical properties, the thermal conductivity of traditional compressor housings (steel / aluminum) is low (aluminum is about 210W / m·K), resulting in insufficient heat dissipation efficiency. This leads to long-term high-temperature operation of the compressor, evaporation of lubricating oil, and a decrease in system energy efficiency. They also have certain limitations in terms of weight, heat conduction, and corrosion resistance.
[0004] The technical problem to be solved by this application is: how to solve the problem of low heat dissipation efficiency of the compressor casing. Utility Model Content

[0007] In some embodiments, several heat dissipation ribs are evenly distributed along the axial direction of the housing body.
[0008] In some implementations, the heat dissipation grid is made of graphene.
[0009] In some embodiments, the inner wall of the housing body is provided with turbulence protrusions, the axial direction of the turbulence protrusions is consistent with the axial direction of the housing body, and several turbulence protrusions are evenly arranged on the inner wall of the housing body.
[0010] In some embodiments, the main body of the shell is configured as a hollow cylinder, and the ends of the shell are configured as hemispherical.
[0011] In some embodiments, the housing ends are located at both ends of the housing body, and the housing body and the housing ends are connected to form a closed structure.
[0012] The beneficial effects of this utility model are as follows:
[0013] This refrigeration compressor housing structure, by combining the reinforcing function of directional heat dissipation fins, forms a three-dimensional heat conduction network within the metal matrix, directionally guiding heat to the housing surface. This significantly enhances the structural strength and fatigue resistance of the housing, enabling it to withstand higher operating pressures and extending its service life.

[0019] The main body 1 of the shell is set as a hollow cylinder, and the end 2 of the shell is set as a hemispherical shape.
[0020] The outer wall of the main body 1 is provided with heat dissipation ribs 3, which are arranged in a ring. Several heat dissipation ribs 3 are evenly distributed along the axial direction of the main body 1. The heat dissipation ribs 3 are composed of a metal substrate and a heat dissipation mesh. The heat dissipation mesh is a three-dimensional mesh structure embedded in the metal substrate. The heat dissipation ribs 3 can significantly enhance the structural strength and fatigue resistance of the main body 1, allowing it to withstand higher working pressures and extend its service life. Specifically, the metal substrate is made of aluminum alloy, and the heat dissipation mesh is made of graphene. Graphene not only has good thermal conductivity, but its chemical stability effectively resists corrosive substances in ammonia refrigeration systems, greatly improving the corrosion resistance of the shell and reducing maintenance costs.
