Abstract
The utility model discloses a compressor cylinder body, which comprises a compressor cylinder body, wherein the bottom of the compressor cylinder body is provided with a mounting cavity for mounting a controller, and the surface of one side of the mounting cavity, which is close to the bottom of the cylinder body, is rugged.
Description
Technical Field
The utility model relates to the technical field of automobile accessories, in particular to a compressor cylinder body.
Background
In recent years, new energy automobiles are becoming more popular due to the upgrading of energy structures, and the application of electric scroll compressors to air conditioning systems of electric automobiles is also becoming more widespread.
The electric air conditioner compressor controller and the compressor are integrated into a whole, as shown in fig. 1, the automobile compressor controller 102 is attached to the outer side of the bottom of the cylinder 101, and the controller mainly dissipates heat through heat exchange on the outer surface of the shell of the compressor cylinder; because of poor heat dissipation, overheat burnout of the controller has become one of the common failure modes of the electric compressor.
Disclosure of Invention
In view of the above, the present utility model provides a compressor cylinder, which increases the heat dissipation efficiency by increasing the surface area of the mounting cavity of the bottom controller of the cylinder, and the technical scheme of the present utility model is as follows:
the compressor cylinder body comprises a compressor cylinder body, wherein an installation cavity for installing a controller is formed in the bottom of the compressor cylinder body, and the surface of one side of the installation cavity, which is close to the bottom of the cylinder body, is rugged.
Preferably, the surface of the mounting cavity, which is close to the bottom of the cylinder body and has uneven surface, is composed of a plurality of protrusions and grooves which are arranged at intervals.
Preferably, the cross section of the protrusion is at least one of inverted U-shaped, rectangular, triangular or trapezoidal.
Preferably, the two sides of the protrusion, which are close to the groove, are curved surfaces.
Preferably, the grooves are flat or curved.
The beneficial effects are that:
according to the utility model, the bottom of the cylinder body is designed into the concave-convex structure shape from the plane, so that the heat exchange area of the bottom of the cylinder body is increased, the heat dissipation efficiency is improved, the generation of accumulated heat is prevented, the overheat burning of the controller is effectively prevented, and the service life and the stability of the controller are improved.

In the figure: 101-compressor cylinder body, 102-controller, 201-mounting chamber.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, and it is apparent that the described embodiments of the present utility model are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden on the person of ordinary skill in the art based on embodiments of the present utility model, are within the scope of the present utility model.
Example 1
Referring to fig. 2, a compressor cylinder body includes a compressor cylinder body 101, a mounting cavity 201 for mounting a controller is provided at the bottom of the compressor cylinder body 101, the controller is attached to the outer side of the bottom of the compressor cylinder body 101, and transfers heat generated by the controller by contacting with the surface of the cylinder body 101, and can realize surface heat exchange by using a refrigerant (with a temperature of about 30 ℃) flowing through the bottom of the cylinder body 101, the surface of the mounting cavity near one side of the bottom of the cylinder body 101 is uneven, the uneven surface is composed of a plurality of protrusions and grooves which are arranged at intervals, the cross section of the protrusions is at least one of inverted U-shape, rectangle, triangle or trapezoid, and the grooves are planes; in this embodiment, the cross section of the protrusion is rectangular; the protrusion and the groove enable the contact area of the controller and the cylinder body 101 to be increased, the contact area of the refrigerant flowing through the protrusion and the cylinder body bottom can be effectively increased, the heat exchange area of the installation cavity with the concave-convex structure is increased by 32.4% compared with that of the installation cavity with the plane type, the heat carried away by the refrigerant from the cylinder body bottom can be further increased, namely the heat exchange amount of the refrigerant and the cylinder body bottom is increased, the structure can enable flowing gas to generate vortex, the heat transfer efficiency is improved, thereby achieving better heat dissipation effect, further reducing the temperature of the cylinder body bottom, further expanding the temperature difference between the inner side and the outer side of the cylinder body bottom, accelerating the conduction of the heat in the installation cavity of the controller, such as the inner side of the cylinder body bottom, so as to reduce the temperature load in the installation cavity of the controller, thereby improving the working environment temperature of the controller, and improving the service life and stability of the controller.
Example 2
The utility model provides a compressor cylinder body, includes compressor cylinder body 101, compressor cylinder body 101 bottom is equipped with the installation cavity 201 of installation controller, the installation cavity is close to cylinder body 101 bottom one side surface roughness, the surface of roughness comprises protruding and the recess that a plurality of interval set up, the both sides that the arch is close to the recess are the curved surface, the recess is plane or curved surface, works as when the recess is the curved surface, the curved surface of recess highly be less than protruding height.
