As shown in fig. 1 to 4, the present disclosure provides a controller of a compressor, which may be used in an air conditioning system. The controller comprises a shell 1, electronic components and a heat dissipation plate 2 formed in the shell 1, the heat dissipation plate 2 divides the interior of the shell 1 into a first cavity 11 and a second cavity 12, the electronic components are mounted on the heat dissipation plate 2 and located in the first cavity 11, a refrigerant inlet 13 communicated with the second cavity 12 is formed in the shell 1, a heat dissipation channel 21 is formed in the heat dissipation plate 2, one end of the heat dissipation channel 21 is communicated with the refrigerant inlet 13, so that a refrigerant flows into the heat dissipation channel 21 through the refrigerant inlet 13, and the electronic components can dissipate heat through the heat dissipation channel 21.

Through the technical scheme, the refrigerant inlet 13 is formed in the shell 1 of the controller, the heat dissipation channel 21 communicated with the refrigerant inlet 13 is formed in the controller, so that a refrigerant can enter the controller through the refrigerant inlet 13 and flow in the heat dissipation channel 21, the heat of the electronic component above the heat dissipation channel 21 is taken away, the heat dissipation and cooling of the electronic component in the controller are achieved, the controller is ensured to operate at a proper working temperature, and the service life of the controller is prolonged.

Alternatively, in another embodiment provided by the present disclosure, referring to fig. 2, the heat dissipation channel 21 may include a first heat dissipation channel 211, a plurality of flow guiding ribs 22 are formed on the heat dissipation plate 2, the plurality of flow guiding ribs 22 are located in the second chamber 12, and the first heat dissipation channel 211 is defined between two adjacent flow guiding ribs 22. The flow guiding ribs 22 may serve as sidewalls of the first heat dissipating passage 211 to define the first heat dissipating passage 211, so as to guide the refrigerant flowing from the refrigerant inlet 13 to flow along the first heat dissipating passage 211 to take away heat of the electronic component, and may serve as reinforcing ribs of the heat dissipating plate 2 to reinforce the structural strength of the heat dissipating plate 2.

Wherein, the sleeve 23 is formed with an opening 24 for the refrigerant to flow into the inside of the sleeve 23, and the inner wall of the sleeve 23 defines a second heat dissipation channel 212. In the prior art, the circumferential side wall of the sleeve 23 is generally a closed structure, and for an electronic component arranged above the sleeve 23 (a projection of the electronic component on the heat dissipation plate 2 is at least partially overlapped with a projection of the sleeve 23 on the heat dissipation plate 2), since the refrigerant cannot flow into the sleeve 23 through the axial side wall of the sleeve 23, the electronic component located above the sleeve 23 cannot be subjected to heat dissipation and cooling through the refrigerant, however, in the above embodiment provided by the present disclosure, since the opening 24 is formed on the sleeve 23, the refrigerant can be allowed to flow into the sleeve 23 through the opening 24, and the inside of the sleeve 23 is the second heat dissipation channel 212, so that the electronic component located above the sleeve 23 can also be subjected to heat dissipation and cooling.

Alternatively, in still another embodiment provided by the present disclosure, as shown in fig. 2, the heat dissipation channel 21 may include the first heat dissipation channel 211 and the second heat dissipation channel 212 described above. That is to say, the heat dissipation plate 2 is provided with the plurality of flow guiding ribs 22 to define the first heat dissipation channel 211, and is further provided with the sleeve 23 having the opening 24, so that the refrigerant can flow into the sleeve 23 through the opening 24, thereby improving the heat dissipation area and the heat dissipation efficiency, and ensuring that all electronic components can dissipate and cool heat through the first heat dissipation channel 211 and the second heat dissipation channel 212 as much as possible.

For the embodiment of the heat dissipating plate 2 having the plurality of flow guiding ribs 22 formed thereon, optionally, referring to fig. 2, at least two flow guiding ribs 22 extend toward the refrigerant inlet 13 to form the extending portions 223, and flow guiding openings 2231 are formed between two adjacent extending portions 223, so that the refrigerant can flow into the heat dissipating channels 21 between the flow guiding ribs 22 formed with the extending portions 223 through the flow guiding openings 2231. When the refrigerant enters the second chamber 12 from the refrigerant inlet 13, the flow guide port 2231 can guide and concentrate the refrigerant entering the second chamber 12, and it is ensured that most of the refrigerant flows into the first heat dissipation channel 211 between the flow guide ribs 22 forming the extension portions 223 through the flow guide port 2231 as much as possible and flows along the first heat dissipation channel 211 (i.e., flows according to the heat dissipation path defined by the flow guide ribs 22), so that the refrigerant can effectively absorb heat of the electronic component, and the heat dissipation efficiency is improved.

Alternatively, the diversion opening 2231 may be disposed opposite to the refrigerant inlet 13, so that the diversion opening 2231 concentrates and guides the refrigerant when the refrigerant flows out from the refrigerant inlet 13, and ensures that most of the refrigerant flows into the first heat dissipation channel 211 as much as possible.

Here, the number of the extension portions 223 may be set according to a specific arrangement of the plurality of air guide ribs 22. For example, each of the flow guiding ribs 22 may extend toward the refrigerant inlet 13 and form the extension portions 223, so that a flow guiding opening 2231 is defined between two adjacent extension portions 223, that is, each of the first heat dissipation channels 211 has a flow guiding opening 2231 corresponding thereto; alternatively, two of the flow guide ribs 22 located at the outermost side among the plurality of flow guide ribs 22 may extend toward the refrigerant inlet 13 to form an extension portion 223, and the two extension portions 223 define the flow guide opening 2231, that is, one end of each first heat dissipation channel 211 corresponds to the flow guide opening 2231 and is communicated with the flow guide opening 2231.

In order to improve the guiding effect of the diversion rib 22 on the refrigerant, and enable the refrigerant to flow in the first heat dissipation channel 211 defined by the diversion rib 22 as much as possible, as an optional implementation mode, the central axis of the refrigerant inlet 13 is located between one end of the diversion rib 22, which is far away from the heat dissipation plate 2, and the heat dissipation plate 2, that is, the diversion rib 22 extends from the heat dissipation plate 2 towards the direction far away from the first cavity 11 and protrudes out of the central axis of the refrigerant inlet 13, so that the refrigerant flow is guided better, more refrigerants flow in the first heat dissipation channel 211 as much as possible, and the heat dissipation efficiency is improved. In the case where the heat dissipation plate 2 is provided with the ribs and the ribs are at least partially located in the first heat dissipation channel 211, the above embodiment can also reduce the effect of the ribs on the refrigerant flow, and prevent the refrigerant from stopping flowing in the first heat dissipation channel 211 due to the ribs.

In addition, the ribs 22 may have any suitable shape and arrangement.

Because the sleeve 23 is formed on the heat dissipation plate 2, the first flow guiding rib 221 and the second flow guiding rib 222 can be arranged outside the sleeve 23, on one hand, mechanical interference between the flow guiding rib 22 and the sleeve 23 can be avoided, and on the other hand, a flow channel for the refrigerant to flow through is defined between the first flow guiding rib 221 and the second flow guiding rib 222 and the side wall of the sleeve 23. In addition, the first flow guiding rib 221 and the second flow guiding rib 222 are both configured to be arc-shaped structures extending along the circumferential direction of the sleeve 23, so that the first heat dissipation sub-channel 2111 and the second heat dissipation sub-channel 2112 are also formed to be arc-shaped structures, thereby reducing the flow velocity of the refrigerant flowing in the first heat dissipation sub-channel 2111 and the second heat dissipation sub-channel 2112, and improving the heat dissipation effect of the refrigerant. In this exemplary embodiment, the sidewall of the sleeve 23 may be formed in a closed structure so that the refrigerant flows outside the sleeve 23, or the sleeve 23 may be formed with an opening 24 through which the refrigerant flows into the sleeve 23 so that the refrigerant can flow into the sleeve 23, and the present disclosure does not limit a specific position and a specific configuration of the diversion port 2231, as long as at least two diversion ribs 22 extend toward the refrigerant inlet 13 and form the extension portions 223 and the diversion port 2231 is defined between two adjacent extension portions 223.

The IGBT power module 3 is limited to move in the vertical direction, so that the IGBT power module 3 is fixed, fasteners such as bolts are prevented from being used, and the situation of high-voltage electric leakage is prevented.

Optionally, the shape and size of the through hole 41 are adapted to the shape and size of the pin of the IGBT power module 3 to reduce the amount of displacement of the IGBT power module 3 in the horizontal direction.
