Detailed Description
The following description of the embodiments refers to the accompanying drawings, which are included to illustrate specific embodiments in which the utility model may be practiced.
As shown in fig. 1 and 2, the present embodiment discloses a car air conditioner compressor including a cylinder head for the car air conditioner compressor. The cylinder cover for the automobile air conditioner compressor comprises a cylinder cover body 1, wherein the cylinder cover body 1 comprises an outer cover part 11 and an inner cover part 12, an outer cavity 13 is formed between the outer cover part 11 and the inner cover part 12, and an inner cavity 14 is formed inside the inner cover part 12. The refrigerant circulates in the automobile air-conditioning compressor through the fluidity generated by the high-low pressure conversion of the inner cavity 14 and the outer cavity 13, so that the refrigeration performance of the automobile air-conditioning compressor is greatly improved. Meanwhile, the outer cavity 13 and the inner cavity 14 are completely isolated, so that the service life of the automobile air-conditioning compressor is effectively prolonged.
The outer side surface of the cylinder cover body 1 is provided with a pressure relief hole 16, and the pressure relief hole 16 is communicated with the inner cavity 14. When the internal pressure of the automobile air-conditioning compressor exceeds the upper limit value, energy can be released through opening of the pressure relief hole 16, the device in the automobile air-conditioning compressor is prevented from being damaged by the pressure and the energy, and the safety and the stability of the automobile air-conditioning compressor are further improved.
The automobile air conditioner compressor also comprises a pressure relief valve which is connected in the pressure relief hole 16. When the internal pressure of the automobile air-conditioning compressor exceeds the upper limit value of the pressure release valve, the pressure release valve can be opened to release energy, and therefore the effect of improving the safety of the automobile air-conditioning compressor is achieved.
A central hole 15 is formed in the cylinder cover body 1, the central hole 15 is positioned in the inner cavity 14, and the central hole 15 is communicated with the outer cavity 13. The whole structure of the cylinder cover is simple and small, the space and the failure rate are reduced, and the service life of the automobile air conditioner compressor is further prolonged.
The cylinder cover for the automobile air conditioner compressor further comprises a mounting leg 2, the mounting leg 2 is connected to the outer surface of the cylinder cover body 1, and the mounting leg 2 is provided with a fixing hole 21. A cylinder head for vehicle air conditioner compressor is convenient for install on suitable vehicle support through fixed orifices 21, realizes that the complete machine assembly is very convenient.
Wherein, the mounting leg 2 is integrally formed with the cylinder head body 1. The cylinder cover for the automobile air-conditioning compressor is convenient to machine and manufacture, the overall structure of the cylinder cover for the automobile air-conditioning compressor is high in strength, and the safety and stability of the automobile air-conditioning compressor are greatly improved.
The cylinder head body 1 has suction and exhaust holes 17 on its outer surface. The interior of the automobile air-conditioning compressor is communicated with the outside through the air suction and exhaust hole 17, so that air can be sucked or exhausted from the interior of the automobile air-conditioning compressor through the air suction and exhaust hole 17.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the utility model is not limited by the scope of the appended claims.
