the present embodiment provides a compressor 100, the compressor 100 comprising a compressor housing 110, a controller assembly 120, a motor assembly 130, and an external cooling system 140;

the compressor housing 110 has an inner cavity 111, and the compressor housing 110 is provided with an intake passage 112 and an exhaust passage 113 which are communicated with the inner cavity 111; the intake passage 112 and the exhaust passage 113 communicate with an exhaust port 141 and an intake port 142 of the external cooling system 140, respectively. The controller assembly 120 is connected to the compressor housing 110, the motor assembly 130 is accommodated in the inner cavity 111, and the air outlet 141 and the air inlet 142 of the external cooling system 140 are respectively communicated with the air inlet passage 112 and the air outlet passage 113.

The working principle of the compressor 100 is:

referring to fig. 1 to 4, in the operation process of the compressor 100, the controller assembly 120 and the motor assembly 130 located in the inner cavity 111 both generate heat, and since the controller assembly 120 and the motor assembly 130 are both connected to the compressor housing 110, the heat generated by the controller assembly 120 and the motor assembly 130 is transferred to the compressor housing 110.

The compressor housing 110 is provided with an air inlet passage 112 and an air outlet passage 113 which are communicated with the inner cavity 111 of the compressor housing; and the intake passage 112 and the exhaust passage 113 communicate with an exhaust port 141 and an intake port 142 of the external cooling system 140, respectively. Accordingly, the intake passage 112 and the exhaust passage 113 can jointly form a cooling system that radiates heat to the compressor housing 110 after communicating with the external cooling system 140.

Therefore, since the air inlet channel 112 and the air outlet channel 113 are both disposed on the compressor housing 110 and communicated with the inner cavity 111 thereof, the refrigerant output by the external cooling system 140 can pass through the heat in the compressor housing 110 and the inner cavity 111 after entering the air inlet channel 112, that is, the heat in the compressor housing 110 and the inner cavity 111 to which the refrigerant absorption controller assembly 120 and the motor assembly 130 are transferred is absorbed, so that the heat in the compressor housing 110 and the inner cavity 111 can be derived, and further, the temperature of the compressor 100 in the operation process can be effectively reduced, so that the normal operation of the motor assembly 130 and the controller assembly 120 is ensured, and the reduction of the working efficiency of the compressor 100 due to the influence of the temperature is avoided.

Referring to fig. 1-4, in the present embodiment, when the air inlet channel 112 and the air outlet channel 113 are disposed, the air inlet channel 112 and the air outlet channel 113 are respectively located at two ends of the compressor housing 110 along the extending direction of the compressor housing 110. Also, the intake passage 112 may include an intake end 118 for communicating with an exhaust port 141 of the external cooling system 140, and a diversion passage 119; the inlet end 118 and the drainage channel 119 are both in communication with the lumen 111. It should be noted that the air inlet 118 may be directly communicated with the diversion channel 119, so that the refrigerant input to the air inlet 118 can enter the diversion channel 119 through the air inlet 118 to absorb heat of the compressor housing 110; the air inlet 118 may also be indirectly communicated with the flow guiding channel 119 through the inner cavity 111, so that the refrigerant input to the air inlet 118 can enter the inner cavity 111, and the refrigerant in the inner cavity 111 can enter the flow guiding channel 119 to absorb heat of the compressor housing 110.

Further, referring to fig. 1-4, in the present embodiment, the compressor housing 110 further includes a mounting portion 114 for mounting the controller assembly 120, and the mounting portion 114 is separated from the inner cavity 111; an intake passage 112 opens in the compressor housing 110 between the mounting portion 114 and the inner cavity 111. It should be noted that the mounting portion 114 may be a groove structure on the surface of the compressor housing 110, and a cover plate for closing the mounting portion 114 may be further provided to isolate the controller assembly 120 in the mounting portion 114 from the outside. In other embodiments of the present invention, when the mounting portion 114 is provided, the mounting portion 114 may also adopt other forms of structures.

When the air inlet passage 112 is formed, in order to increase the heat dissipation area and improve the heat dissipation effect on the controller assembly 120, the air inlet passage 112 is a strip-shaped passage formed along the extending direction of the mounting portion 114. Therefore, the air inlet channel 112 is a long strip-shaped channel which is arranged along the extending direction of the installation part 114, so that the area of heat exchange with the installation part 114 can be increased in the process of radiating the compressor shell 110 through the air inlet channel 112, the radiating effect on the controller assembly 120 can be increased, and the overhigh temperature of the controller assembly 120 in the working process can be avoided.

Further, referring to fig. 1-4, in the present embodiment, since the inner cavity 111 of the compressor housing 110 is used for accommodating the motor assembly 130, the motor assembly 130 can be further cooled by conducting the air inlet channel 112 and the inner cavity 111 during the operation of the motor assembly 130, so as to avoid an over-high operation temperature of the motor assembly 130.

The wall of the inner cavity 111 is provided with a mounting groove 115, the mounting groove 115 is used for mounting a bearing 122, and the bearing 122 is used for being connected with a main shaft 121 of the motor; the mounting groove 115 communicates with the intake passage 112. Specifically, the bottom of the mounting groove 115 is provided with an air guide hole 116, and the mounting groove 115 is communicated with the air inlet channel 112 through the air guide hole 116. It should be noted that, in other embodiments of the present invention, in order to enable the mounting groove 115 to communicate with the air inlet channel 112, the mounting groove 115 may also communicate with the inner cavity 111, and the air inlet channel 112 communicates with the inner cavity 111, so that the refrigerant in the air inlet channel 112 may enter the mounting groove 115 after entering the inner cavity 111.

Therefore, by means of the arrangement mode, the refrigerant in the air inlet channel 112 can be conveyed into the mounting groove 115 through the conduction mode of the air inlet channel 112 and the air guide hole 116, so that the bearing 122 can be cooled, the phenomenon that the lubricating effect is poor due to overhigh temperature of the bearing 122 can be avoided, and the normal operation of the motor assembly 130 can be guaranteed. It should be noted that, in the present embodiment, the refrigerant is an oil-gas mixture, so that in the process of the refrigerant dissipating heat from the bearing 122, the grease of the refrigerant shaft can also lubricate the bearing 122, and further can ensure the lubricating effect of the bearing 122.

Further, referring to fig. 1-4, in the present embodiment, as can be seen from the above, the air inlet channel 112 is disposed on the compressor housing 110 between the mounting portion 114 and the inner cavity 111, and in order to improve the heat dissipation effect of other positions of the compressor housing 110, the air inlet channel 112 is communicated with the inner cavity 111, and at the same time, the compressor housing 110 may further be disposed with a flow guide channel, both ends of the flow guide channel are communicated with the inner cavity 111; and the guide passage extends from the end of the compressor housing 110 where the intake passage 112 is provided to the end where the exhaust passage 113 is provided. Therefore, by providing the flow guide passage, the refrigerant in the inner cavity 111 can be introduced into the flow guide passage, so that the area for exchanging heat with the compressor housing 110 is increased by increasing the contact area with the compressor housing 110, and the temperature of the compressor housing 110 can be further reduced.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
