As a result, the first cooling space a and the second cooling space b form a single communicating entire space, and the first cooling space a and the second cooling space b communicate with the external heat exchanger through the inlet/outlet 221, so that the refrigerant can flow through the first cooling space a, the second cooling space b, and the heat exchanger in the sealed space formed by the compression mechanism portion 2 and the heat exchanger. That is, the liquid refrigerant evaporates and absorbs heat in the first cooling space a and the second cooling space b to form gas, the gas enters the heat exchanger through the inlet/outlet 221, the gaseous refrigerant is solidified and releases heat in the heat exchanger to form liquid, and the liquid refrigerant flows into the first cooling space a and the second cooling space b through the inlet/outlet 221 to be evaporated, so that the refrigerant flows back and forth in the sealed space formed by the compression mechanism 2 and the heat exchanger to exchange heat.
When the compressor 100 is operated, the refrigerant in the cylinder 4 generates a large amount of heat during the compression. Since the piston 21 and the sliding vane 22 are disposed in the cylinder 4 of the compressor 100 and are movable relative to the cylinder 4, the refrigerant can evaporate and absorb heat in the first cooling space a and the second cooling space b, thereby performing a cooling function, so that the temperature in the cylinder 4 can be effectively reduced, the discharge temperature and the energy consumption of the compressor 100 can be reduced, and the performance and the operation reliability of the compressor 100 can be improved.

Thus, since the first opening 221a is located above the second opening 221b, it can be understood that most of the gaseous refrigerant in the first cooling space a and the second cooling space b flows into the heat exchanger from the first opening 221a, and most of the liquid refrigerant in the heat exchanger flows into the first cooling space a and the second cooling space b through the second opening 221b, so that a refrigerant circuit is formed in the space where the compression mechanism section 2 and the heat exchanger are sealed. Therefore, the refrigerant can flow among the first cooling space a, the second cooling space b and the heat exchanger conveniently, the cooling effect of the compression mechanism part 2 can be enhanced, the cooling effect of the compression mechanism part 2 on the gas in the cylinder 4 is improved, the exhaust temperature and the energy consumption of the compressor 100 are reduced, and the performance and the operation reliability of the compressor 100 are improved.
Alternatively, as shown in fig. 3 and 5, the first opening 221a and the second opening 221b are located on an end surface of the trailing end of the slider 22. Therefore, the flowing time of the refrigerant in the first cooling space a and the second cooling space b can be ensured, namely, the evaporation time of the refrigerant in the first cooling space a and the second cooling space b is ensured, and further, the cooling effect of the compression mechanism part 2 on the gas in the cylinder 4 is enhanced.

While ensuring the heat exchange effect of the heat exchanger, it is advantageous to reduce the manufacturing cost of the compressor 100. It is to be understood that the type of the heat exchanger is not limited thereto as long as the cooling effect of the compression mechanism portion 2 on the gas in the cylinder 4 is ensured by the cooling effect of the compression mechanism portion 2.
Specifically, the first cooling space a has a circular cross section. Thereby making the piston 21 simple in structure and convenient to manufacture. Here, the shape of the cross section of the first cooling space a is not limited to this, and may be formed in other shapes as long as the evaporation heat absorption effect of the refrigerant in the first cooling space a is ensured.
