Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy die-casting, in particular to an integrally formed aluminum alloy die-casting. Background Art

[0002] The refrigerator compressor is a relatively important component in the refrigerator. The refrigerator compressor is the component that produces cold air in the refrigerator. The refrigerator compressor includes an outer shell and internal refrigeration components. The operation of the internal refrigeration components is a process of heat exchange. The cylinder head inside the compressor is the main heat-generating component. The heat generated by the piston inside the cylinder will affect the performance and life of the cylinder. The cylinder head is the main heat dissipation part of the cylinder and needs to have good heat dissipation performance.

[0003] The heat dissipation performance is not only related to the structure and thickness of the cylinder head, but also to the thermal conductivity of the material. The heat dissipation performance cannot be improved through structural design. Only materials with better thermal conductivity can be selected as the material for producing the shell. The thermal conductivity gradient of metals is silver, gold, and aluminum. Silver and gold are very rare and precious and cannot be mass-produced. Aluminum can be mass-produced, but the material hardness is not high. For this reason, aluminum alloy materials are generally used as the shell material of the compressor. Although aluminum alloy materials have high strength and meet the installation requirements of the compressor, the thermal conductivity of aluminum alloys is also lower than that of pure aluminum materials.

[0004] To this end, an integrated aluminum alloy die-casting is proposed. The cylinder head is made by inlaying aluminum alloy and pure aluminum into an integrated molding method, thereby improving the overall material thermal conductivity while ensuring the material strength. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An integrally formed aluminum alloy die-casting comprises an aluminum alloy plate, wherein the aluminum alloy plate comprises a solid layer and a mesh layer, wherein a plurality of the solid layers and mesh layers are provided, and the plurality of the solid layers and mesh layers are arranged at intervals, wherein an aluminum layer is attached to the mesh layer, and the solid layer, the mesh layer and the aluminum layer are integrally formed.

[0008] Preferably, a plurality of through holes are formed on each of the plurality of mesh layers, the thickness of the mesh layer is less than the thickness of the solid layer, and the thickness of the aluminum layer is consistent with that of the solid layer.

A plurality of convex strips 4 are provided on the outer surface of the plurality of aluminum layers 2, and the plurality of convex strips 4 are all in the shape of triangles.
