[0045] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0046] The heat sink 20 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0047] Reference Figure 2-Figure 11 According to the radiator 20 of the first embodiment of the utility model, the radiator 20 is used to dissipate heat from the electric control box 10a of the outdoor unit 100. The outdoor unit 100 has a compressor cavity 101 and a fan cavity 102 arranged along a first direction (refer to the left and right direction of the drawing), the first direction is parallel to the horizontal direction, and the radiator 20 is suitable for thermal connection with the electric control box 10a and the radiator 20 is located in the fan cavity 102. Among them, a middle partition 15 can be provided between the compressor cavity 101 and the fan cavity 102, and the electric control box 10a can be installed on the middle partition 15.

[0048] The electric control box 10a contains a plurality of components, at least some of which have relatively high power, for example, the fan IPM module, the compressor IPM module, the rectifier bridge stack, the PFC drive power tube and the PFC freewheeling diode have relatively high power. When the outdoor unit 100 is working, the components in the electric control box 10a will generate relatively large heat, resulting in an increase in the temperature of the electric control box 10a. By providing a radiator 20, the radiator 20 is thermally connected to the electric control box 10a and is used to dissipate heat from the components of the electric control box 10a. When the airflow flows through the radiator 20, part of the heat from the radiator 20 can be taken away, thereby reducing the temperature of the components in the electric control box 10a, realizing the heat dissipation function of the radiator 20 on the electric control box 10a, and further ensuring the stability of the operation of the outdoor unit 100.

[0049] In addition, by installing the electric control box 10a on the middle partition 15 and disposing the radiator 20 in the fan cavity 102, the space inside the outdoor unit 100 can be fully utilized, the space utilization rate is improved, and the overall structure inside the outdoor unit 100 is more compact.

[0050] Optionally, the heat sink 20 may be in direct contact with components of the electric control box 10 a , and the electric control box 10 a is directly thermally connected to the heat sink 20 to transfer heat.

[0051] Optionally, a heat-conducting layer may be provided between the heat sink 20 and the components of the electric control box 10a, and a heat-conducting connection is performed through the heat-conducting layer.

[0052] The radiator 20 has a heat dissipation channel 23, which is in communication with both the fan cavity 102 and the compressor cavity 101. The fan cavity 102 is provided with an outdoor fan 13, and the compressor cavity 101 is provided with a compressor. The heat dissipation channel 23 is in communication with the fan cavity 102, and the airflow generated by the outdoor fan 13 during operation can take away the heat of the radiator 20 after flowing through the heat dissipation channel 23 of the radiator 20, thereby reducing the heat of the components in the electric control box 10a. In addition, during the operation of the outdoor fan 13, a low-pressure area will be formed in the fan chamber 102. By providing a heat dissipation channel 23 and the heat dissipation channel 23 being connected to both the fan chamber 102 and the compressor chamber 101, the air in the compressor chamber 101 flows toward the radiator 20 under the action of the pressure difference between the compressor chamber 101 and the fan chamber 102, and can flow into the fan chamber 102 after passing through the heat dissipation channel 23. In the process of the air in the compressor chamber 101 flowing into the fan chamber 102 through the heat dissipation channel 23, part of the heat of the radiator 20 can be taken away, thereby further accelerating the heat dissipation of the components in the electrical control box 10a by the radiator 20, so that the components in the electrical control box 10a are within the normal operating temperature, thereby ensuring the stability of the operation of the outdoor unit 100.

[0053] The radiator 20 includes a first heat dissipation zone 24 and a second heat dissipation zone 25 arranged along a first direction. The second heat dissipation zone 25 is located on a side of the first heat dissipation zone 24 adjacent to the compression chamber 101. The airflow generated during the operation of the outdoor fan 13 in the fan chamber 102 will flow to the first heat dissipation zone 24, and can take away part of the heat of the first heat dissipation zone 24 of the radiator 20; during the operation of the outdoor fan 13, a low-pressure zone will be formed in the fan chamber 102, and the air in the compressor chamber 101 will flow toward the second heat dissipation zone 25 of the radiator 20 under the action of the pressure difference between the compressor chamber 101 and the fan chamber 102, and can take away part of the heat of the second heat dissipation zone 25 of the radiator 20.

[0054] The height dimension of the first heat dissipation area 24 in the vertical direction increases from the fan cavity 102 to the compressor cavity 101 and / or the height dimension of the second heat dissipation area 25 in the vertical direction increases from the compressor cavity 101 to the fan cavity 102.

[0055] For example, the height dimension of the first heat dissipation area 24 in the vertical direction increases in the direction from the fan chamber 102 to the compressor chamber 101. The airflow generated during the operation of the outdoor fan 13 in the fan chamber 102 can flow to the first heat dissipation area 24 of the radiator 20 more smoothly and fully contact and exchange heat with the first heat dissipation area 24, thereby improving the heat dissipation effect of the radiator 20. In addition, the height dimension of the first heat dissipation area 24 in the vertical direction increases in the direction from the fan chamber 102 to the compressor chamber 101, so that there is a certain safety distance between the outdoor fan 13 and the first heat dissipation area 24, while avoiding the interference between the left radiator 20 and the outdoor fan 13, the structure of the radiator 20 is optimized, so that the radiator 20 has a larger volume, so that the first heat dissipation area 24 of the radiator 20 has a larger contact area with the airflow, which can further improve the heat dissipation effect, and can make full use of the internal space of the outdoor unit 100, improve the space utilization rate of the internal space of the outdoor unit 100, and make the overall structure of the internal space of the outdoor unit 100 more compact.

[0056] For example, the height dimension of the second heat dissipation area 25 in the vertical direction increases in the direction from the compressor cavity 101 to the fan cavity 102. During the operation of the outdoor fan 13, a low-pressure area will be formed in the fan cavity 102, and the air in the compressor cavity 101 flows toward the right radiator 20 of the radiator 20 under the pressure difference between the compressor cavity 101 and the fan cavity 102. By increasing the height dimension of the second heat dissipation area 25 in the vertical direction from right to left, the airflow in the compressor cavity 101 can flow more smoothly to the second heat dissipation area 25 of the radiator 20 and fully contact and exchange heat with the second heat dissipation area 25, thereby improving the heat dissipation effect of the radiator 20. In addition, the height dimension of the second heat dissipation zone 25 in the up and down direction from the compressor chamber 101 to the fan chamber 102 is increased, and while avoiding interference between the left radiator 20 and other components in the outdoor unit 100, the structure of the radiator 20 is optimized, so that the radiator 20 has a larger volume, so that the second heat dissipation zone 25 of the radiator 20 has a larger contact area with the airflow, which can further enhance the heat dissipation effect, and can make full use of the internal space of the outdoor unit 100, thereby improving the space utilization rate of the internal space of the outdoor unit 100, and making the overall structure of the internal space of the outdoor unit 100 more compact.

[0057] For example, the height dimension of the first heat dissipation zone 24 in the vertical direction increases in the direction from the fan chamber 102 to the compressor chamber 101, and the height dimension of the second heat dissipation zone 25 in the vertical direction increases in the direction from the compressor chamber 101 to the fan chamber 102. The airflow generated during the operation of the outdoor fan 13 in the fan chamber 102 can flow more smoothly to the first heat dissipation zone 24 of the radiator 20 and fully contact and exchange heat with the first heat dissipation zone 24, thereby improving the heat dissipation effect of the radiator 20. At the same time, the airflow in the compressor chamber 101 can flow more smoothly to the second heat dissipation zone 25 of the radiator 20 and fully contact and exchange heat with the second heat dissipation zone 25, thereby improving the heat dissipation effect of the radiator 20. In addition, through this arrangement, a certain safety distance can be maintained between the outdoor fan 13 and the first heat dissipation zone 24, while avoiding interference between the first heat dissipation zone 24 and the outdoor fan 13, and avoiding interference between the second heat dissipation zone 25 and other components in the outdoor unit 100. At the same time, the structure of the radiator 20 is optimized, and the internal space of the outdoor unit 100 is fully utilized, so that the radiator 20 has a larger volume, thereby making the radiator 20 have a larger contact area with the airflow, which can further improve the heat dissipation effect of the radiator 20, and can fully utilize the internal space of the outdoor unit 100, improve the space utilization rate of the internal space of the outdoor unit 100, and make the overall structure of the internal space of the outdoor unit 100 more compact.

[0058] According to the radiator 20 of the embodiment of the utility model, the radiator 20 is arranged between the fan chamber 102 and the compressor chamber 101 of the outdoor unit 100 and includes a first heat dissipation area 24 and a second heat dissipation area 25, and the height dimension of the first heat dissipation area 24 in the vertical direction increases from left to right and / or the height dimension of the second heat dissipation area 25 in the vertical direction increases from right to left, so that the airflow of the fan chamber 102 and / or the airflow of the compressor chamber 101 can flow to the radiator 20 more smoothly and fully contact and exchange heat with the radiator 20, thereby improving the heat dissipation effect of the radiator 20. In addition, the height dimension of the first heat dissipation area 24 in the up-down direction increases from left to right and / or the height dimension of the second heat dissipation area 25 in the up-down direction increases from right to left, while avoiding interference between the radiator 20 and other components inside the outdoor unit 100. The structure of the radiator 20 is optimized, and the internal space of the outdoor unit 100 is fully utilized, so that the radiator 20 has a larger volume, thereby making the radiator 20 have a larger contact area with the airflow, which can further improve the heat dissipation effect of the radiator 20.

[0059] Reference Figure 8-Figure 11 According to some embodiments of the utility model, the radiator 20 includes a heat dissipation substrate 21 and a heat dissipation fin group 22. The heat dissipation fin group 22 is connected to the upper side or the lower side of the heat dissipation substrate 21. The heat dissipation substrate 21 is suitable for being thermally connected to the electric control box 10a. By providing the heat dissipation substrate 21 and the heat dissipation fin group 22, the heat generated by the components inside the electric control box 10a can be transferred to the heat dissipation substrate 21 that is thermally connected to the electric control box 10a, and then transferred to the heat dissipation fin group 22 connected to the heat dissipation substrate 21 through the heat dissipation substrate 21. The heat dissipation substrate 21 has good thermal conductivity, which can improve the heat dissipation efficiency of the radiator 20 to a certain extent.

[0060] The heat sink group 22 includes a plurality of heat sinks 30 arranged at intervals in the horizontal direction, and a heat dissipation channel 23 is defined between adjacent heat sinks 30. The heat sink group 22 includes a first heat dissipation area 24 and a second heat dissipation area 25. The heat sink group 22 includes a plurality of heat sinks 30, and the plurality of heat sinks 30 can ensure that the heat sink group 22 has a large contact area with the airflow, thereby ensuring the heat dissipation effect of the radiator 20. In addition, the plurality of heat sinks 30 are arranged at intervals, and two adjacent heat sinks 30 define a heat dissipation channel 23. The airflow can pass through the heat dissipation channel 23 between the two adjacent heat sinks 30 and contact the two heat sinks 30 and can take away the heat on the heat sinks 30, which can further ensure that the heat sink group 22 has a large contact area with the airflow, thereby ensuring the heat dissipation effect of the radiator 20. At the same time, the heat dissipation channel 23 is defined between two adjacent heat sinks 30, and there is no need to separately process and manufacture the heat dissipation channel 23 for the radiator 20, which can reduce the difficulty of processing and manufacturing to a certain extent.

[0061] Optionally, the plurality of heat sinks 30 of the heat sink group 22 may be arranged at equal intervals in the horizontal direction.

[0062] It should be noted that the “plurality” in the present invention refers to two or more than two.

[0063] Reference Figure 8-Figure 9 According to some embodiments of the present invention, the first heat dissipation area 24 includes a plurality of heat dissipation fins 30 arranged at intervals along the first direction, and the height dimensions of the plurality of heat dissipation fins 30 of the first heat dissipation area 24 in the vertical direction increase in sequence in the direction from the fan cavity 102 to the compressor cavity 101. The heat dissipation fins 30 of the first heat dissipation area 24 extend in the front-to-back direction and are arranged at intervals along the first direction, and the height dimensions of the plurality of heat dissipation fins 30 of the first heat dissipation area 24 in the vertical direction increase in sequence in the direction from the fan cavity 102 to the compressor cavity 101, while avoiding the interference between the first heat dissipation area 24 of the radiator 20 and other components inside the outdoor unit 100, the structure of the radiator 20 is optimized, so that a single heat dissipation fin 30 of the first heat dissipation area 24 can have a larger heat dissipation area, so that a single heat dissipation fin 30 has a larger contact area with the airflow, thereby improving the heat dissipation effect of a single heat dissipation fin 30, and further improving the heat dissipation effect of the first heat dissipation area 24 including a plurality of heat dissipation fins 30. In addition, in the direction from the fan cavity 102 to the compressor cavity 101, the height dimensions of the multiple heat sinks 30 in the first heat sink 24 in the vertical direction increase successively, so that the airflow of the fan cavity 102 and / or the airflow of the compressor cavity 101 can flow to the first heat sink 24 of the radiator 20 relatively smoothly, and fully contact and exchange heat with the heat sinks 30 on both sides of the heat sink 23 through the heat sink channel 23, thereby improving the heat dissipation effect of the radiator 20.
