[0038] Embodiments of the present invention are described in detail below, examples of which 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.

[0039] The outdoor unit 100 according to an embodiment of the present invention will be described below with reference to the drawings.

[0040] Reference Figure 1 The outdoor unit 100 according to the first embodiment of the present invention comprises an outdoor housing 10, an outdoor heat exchanger, an outdoor fan 11, a compressor assembly 12, an electric control module 20 and a water heat exchange assembly. The outdoor heat exchanger, the outdoor fan 11, the compressor assembly 12 and the electric control module 20 are all arranged in the outdoor housing 10. The water heat exchange assembly comprises a water heat exchanger 13, and the water heat exchanger 13 has a water flow channel and a refrigerant channel for mutual heat exchange. The outdoor unit 100 can work in a cooling or heating condition. Taking the heating condition as an example, the refrigerant is compressed into a high temperature and high pressure state in the compressor assembly 12 and enters the refrigerant channel of the water heat exchanger 13 to exchange heat with the refrigerant channel in the water heat exchanger 13. After the heat exchange is completed, the refrigerant flows out from the refrigerant channel and flows into the outdoor heat exchanger to realize the heat exchange function of the outdoor heat exchanger. Finally, it flows into the compressor assembly 12 from the outdoor heat exchanger to perform the next heat exchange cycle.

[0041] The water flow channel and the refrigerant channel in the water heat exchanger 13 can realize the heat exchange function of the water heat exchanger 13 by exchanging heat with each other. After the refrigerant in the refrigerant circulation system enters the refrigerant channel of the water heat exchanger 13, the water in the water flow channel exchanges heat with the refrigerant in the refrigerant channel. After the water in the water flow channel flows out of the water heat exchanger 13 after heat exchange, the temperature of the water can be changed. The water adjusted to the preset temperature can be introduced into the room to exchange heat with domestic water or introduced into the indoor heat exchanger of the indoor unit to adjust the indoor air temperature.

[0042] Optionally, the water channel heat exchanger 13 may be a plate heat exchanger.

[0043] The refrigerant circulation system of the outdoor unit 100 includes a cooling unit 42 for dissipating heat from the electric control module 20, the cooling unit 42 is thermally connected to the electric control module 20, and the cooling unit 42 is connected between the refrigerant channel of the water heat exchanger 13 and the outdoor heat exchanger. The water heat exchanger 13 has a first refrigerant inlet and outlet 40 and a second refrigerant inlet and outlet 41 both connected to the refrigerant channel, and the refrigerant flows into the refrigerant channel from one of the first refrigerant inlet and outlet 40 and flows out of the refrigerant channel from the other of the first refrigerant inlet and outlet 40 and the second refrigerant inlet and outlet 41. The outdoor heat exchanger has a first heat exchange inlet and outlet and a second heat exchange inlet and outlet, and the refrigerant flows into the outdoor heat exchanger from one of the first heat exchange inlet and outlet and flows out of the outdoor heat exchanger from the other of the first heat exchange inlet and outlet and the second heat exchange inlet and outlet. The cooling unit 42 is connected between the second refrigerant inlet and outlet 41 and the first heat exchange inlet and outlet.

[0044] For example, when the outdoor heat exchanger acts as an evaporator and the water heat exchanger 13 acts as a condenser, the refrigerant discharged from the compressor assembly 12 flows into the refrigerant channel of the water heat exchanger 13 through the first refrigerant inlet and outlet 40, and flows out from the second refrigerant inlet and outlet 41. Part of the refrigerant flowing out of the water heat exchanger 13 can flow through the cooling part 42 and take away the heat generated by the electronic control module 20. The refrigerant flowing out of the cooling part 42 flows into the outdoor heat exchanger from the first heat exchange inlet and outlet, and flows out of the outdoor heat exchanger from the second heat exchange inlet and outlet, and returns to the compressor to continue the compression cycle. After the refrigerant in the refrigerant circulation system enters the refrigerant channel of the water heat exchanger 13, the water in the water flow channel exchanges heat with the refrigerant in the refrigerant channel. After the heat exchange is completed, the refrigerant flows through the cooling part 42. At this time, the refrigerant flowing into the cooling part 42 has a lower temperature after heat exchange in the water heat exchanger 13, and the refrigerant flowing through the cooling part 42 can achieve the heat dissipation function of the electronic control module 20. Moreover, relative to the refrigerant temperature of the return air pipe in the refrigerant circulation system, the temperature of the refrigerant after passing through the water heat exchanger 13 and before flowing into the outdoor heat exchanger is higher than the refrigerant temperature of the return air pipe while satisfying the heat dissipation of the electric control module 20, which can reduce the risk of condensation caused by the use of refrigerant to dissipate heat from the electric control module 20. In addition, by using the refrigerant after passing through the water heat exchanger 13 to dissipate heat from the electric control module 20, the heat exchange performance of the water heat exchanger 13 can be prioritized to ensure that the indoor heat exchange demand is met.

[0045] When the outdoor heat exchanger acts as a condenser and the water heat exchanger 13 acts as an evaporator, the refrigerant discharged from the compressor assembly 12 flows into the outdoor heat exchanger through the second heat exchange inlet and outlet, and flows out from the first heat exchange inlet and outlet. Part of the refrigerant flowing out of the outdoor heat exchanger can flow through the cooling part 42 and take away the heat generated by the electronic control module 20. The refrigerant flowing out of the cooling part 42 flows into the water heat exchanger 13 from the second refrigerant inlet and outlet 41, and flows out of the water heat exchanger 13 from the first refrigerant inlet and outlet 40, and returns to the compressor to continue the compression cycle. The refrigerant in the refrigerant circulation system enters the outdoor heat exchanger for heat exchange. After the heat exchange is completed, the refrigerant flows through the cooling part 42. At this time, the temperature of the refrigerant flowing into the cooling part 42 is relatively low after heat exchange by the outdoor heat exchanger. The refrigerant flowing through the cooling part 42 can achieve the heat dissipation function of the electronic control module 20. Furthermore, relative to the refrigerant temperature of the return air pipe portion of the refrigerant circulation system, the refrigerant that flows through the outdoor heat exchanger and before flowing into the water heat exchanger 13 can achieve heat dissipation for the electronic control module 20 while having a temperature that is higher than the refrigerant temperature of the return air pipe portion, thereby reducing the risk of condensation caused by using the refrigerant to dissipate heat for the electronic control module 20.

[0046] The cooling part 42 is connected between the outdoor heat exchanger and the water heat exchanger 13. Since the refrigerant between the outdoor heat exchanger and the water heat exchanger 13 is used to dissipate the heat of the electronic control module 20, the temperature of the refrigerant flowing between the water heat exchanger 13 and the outdoor heat exchanger can meet the heat dissipation and cooling effect of the electronic control module 20. At the same time, since the refrigerant temperature of this part is higher than the temperature of the refrigerant in the return air pipe part, the condensation phenomenon caused by using the refrigerant to cool the electronic control module 20 can be reduced or avoided, thereby improving the safety of the whole machine.

[0047] According to the outdoor unit 100 of the embodiment of the present invention, the refrigerant between the outdoor heat exchanger and the water heat exchanger 13 can be used to dissipate heat from the electronic control module 20. At the same time, condensation caused by cooling the electronic control module 20 with the refrigerant can be reduced or avoided, thereby improving the safety of the entire machine.

[0048] Reference Figure 1 According to some embodiments of the present invention, the outdoor unit 100 includes a flow regulating device 45 connected to the refrigerant circulation system, and the flow regulating device 45 is connected between the refrigerant channel of the water heat exchanger 13 and the heat exchanger, and is used to control the refrigerant flowing through the cooling part 42. By providing the flow regulating device 45, the refrigerant flowing through the cooling part 42 can be individually controlled, so that the flow of the refrigerant in the cooling part 42 is within a suitable range, so that the refrigerant flow of the cooling part 42 matches the heat generated by the electric control module 20 during operation, and while ensuring the heat dissipation effect of the electric control module 20, the condensation phenomenon of the electric control module 20 caused by the excessive refrigerant flow through the cooling part 42 is reduced or avoided.

[0049] Reference Figure 1 In some embodiments of the present invention, the refrigerant circulation system includes a connecting pipe 43 and a cooling bypass 44 connected between the refrigerant channel of the water heat exchanger 13 and the heat exchanger. The cooling bypass 44 is connected in parallel with a portion of the connecting pipe 43, and a portion of the cooling bypass 44 constitutes a cooling part 42.

[0050] The refrigerant in the connecting pipe 43 of the refrigerant system is used to ensure the indoor heat exchange performance to achieve the temperature regulation function; the refrigerant in the cooling part 42 of the cooling bypass 44 is used to meet the temperature reduction requirements of the electric control module 20 to achieve the heat dissipation function of the electric control module 20. By arranging at least part of the outlet section of the main pipe in parallel with the cooling bypass 44 and arranging a flow regulating device 45 for controlling the refrigerant flowing through the cooling part 42, it is possible to achieve independent control of the refrigerant flowing through the cooling part 42. Through this arrangement, while completing the heat dissipation function of the electric control module 20, the performance of the outdoor unit 100 can be guaranteed.

[0051] Reference Figure 1 According to some embodiments of the present invention, the cooling bypass 44 is provided with a flow regulating device 45, which is used to control the cooling bypass 44, and the flow regulating device 45 is used to regulate the conduction and cutoff of the cooling bypass 44 and / or the opening of the flow regulating device 45 is adjustable.

[0052] The flow regulating device 45 can control the refrigerant in the cooling bypass 44 by connecting and disconnecting the cooling bypass 44. When the flow regulating device 45 disconnects the cooling bypass 44, the refrigerant with a lower temperature in the connecting pipe 43 cannot continue to enter the cooling bypass 44, thereby reducing the risk of condensation caused by using the refrigerant to dissipate heat from the electric control module 20. For example, when the electric control module 20 can complete the heat dissipation function by self-heating or the temperature of the electric control module 20 is reduced to a certain extent under the cooling effect of the refrigerant, the flow regulating device 45 can disconnect the cooling bypass 44; when the flow regulating device 45 connects the cooling bypass 44, the refrigerant with a lower temperature in the connecting pipe 43 enters the cooling bypass 44, thereby realizing the heat dissipation function of the electric control module 20. For example, when the temperature of the electric control module 20 is high, the flow regulating device 45 connects the cooling bypass 44, thereby improving the heat dissipation effect of the electric control module 20.

[0053] The flow regulating device 45 can control the flow of the refrigerant in the cooling bypass 44 by adjusting the opening. When the temperature of the electronic control module 20 rises during operation, the flow regulating device 45 increases its opening to increase the flow of the refrigerant in the cooling part 42 to ensure the heat dissipation effect; when the temperature of the electronic control module 20 drops to a certain level, the flow regulating device 45 reduces its opening to reduce the flow of the refrigerant in the cooling part 42, thereby reducing or avoiding the excessive refrigerant flow in the cooling part 42 and causing condensation in the electronic control module 20.

[0054] The flow regulating device 45 can also control the refrigerant in the cooling bypass 44 by connecting, disconnecting and adjusting the opening of the cooling bypass 44 to control the flow of the refrigerant. When the temperature of the electric control module 20 is high, the flow regulating device 45 connects the cooling bypass 44 and adjusts the opening according to the working state of the electric control module 20 to ensure the heat dissipation effect of the electric control module 20; when the temperature of the electric control module 20 gradually decreases to a certain range under the cooling effect of the refrigerant, the flow regulating device 45 adjusts the opening or directly disconnects the cooling bypass 44 to reduce or avoid excessive refrigerant flow in the cooling part 42, which may cause condensation in the electric control module 20.

[0055] Reference Figure 1 According to some embodiments of the present invention, the portion of the connecting pipeline 43 connected in parallel with the cooling bypass 44 is a parallel section 431, and the parallel section 431 is provided with a throttling component 46. The throttling component 46 plays a role in controlling the refrigerant flow of the connecting pipeline 43 to ensure the heat exchange effect of the outdoor heat exchanger; the flow regulating device 45 plays a role in controlling the refrigerant flow of the cooling unit 42 to ensure the heat dissipation effect of the electronic control module 20, and at the same time, avoids the condensation phenomenon of the electronic control module 20 caused by the excessive refrigerant flow through the cooling unit 42. In addition, by setting the throttling component 46 in the parallel section 431, it is possible to avoid the throttling component 46 affecting the flow of the refrigerant in the cooling bypass 44 when regulating the flow of the refrigerant in the connecting pipeline 43; and it is possible to greatly reduce the influence of the flow regulating device 45 on the flow of the refrigerant in the connecting pipeline 43 when regulating the flow of the refrigerant in the cooling bypass 44. Thereby, the adjustment of the flow regulating device 45 and the throttling component 46 is more accurate.

[0056] Reference Figure 1 According to some embodiments of the present invention, the outdoor unit 100 further includes a detection component, which is used to detect the temperature and / or dew point temperature of the electronic control module 20. The detection component is electrically connected to the flow regulating device 45 or the electronic control module 20, and the flow regulating device 45 is controlled according to the detection result of the detection component.

[0057] The detection component can detect the temperature of the electronic control module 20 and feed back the detection result to the flow regulating device 45 or the electronic control module 20 electrically connected to the detection component, thereby controlling the opening of the flow regulating device 45 or controlling the flow regulating device 45 to cut off or conduct the cooling bypass 44, so that the refrigerant flow of the cooling part 42 matches the working state and working environment of the electronic control module 20, while ensuring the heat dissipation effect of the electronic control module 20, reducing or avoiding condensation of the electronic control module 20 due to excessive refrigerant flow through the cooling part 42.

[0058] The detection component can detect the temperature and dew point temperature of the electric control module 20, and control the flow regulating device 45 according to the detection result. The detection component can be set with a preset temperature. When the temperature of the electric control module 20 is greater than the sum of the dew point temperature and the preset temperature, there is no risk of condensation in the electric control module 20. The flow regulating device 45 can increase the opening according to the electrical signal transmitted by the detection component, so that the flow of the refrigerant in the cooling part 42 increases to accelerate the heat dissipation process of the electric control module 20; when the temperature of the electric control module 20 is equal to the sum of the dew point temperature and the preset temperature, the risk of condensation in the electric control module 20 is low, and the flow regulating device 45 can maintain the opening according to the electrical signal transmitted by the detection component to ensure the heat dissipation effect; when the temperature of the electric control module 20 is lower than the sum of the dew point temperature and the preset temperature, the risk of condensation in the electric control module 20 is high, and the flow regulating device 45 can reduce the opening or cut off the cooling bypass 44 according to the electrical signal transmitted by the detection component to reduce the condensation risk caused by the use of refrigerant to dissipate heat from the electric control module 20.

[0059] Reference Figure 2-Figure 9 According to some embodiments of the present invention, the outdoor unit 100 further includes a heat dissipation component 30, which can be thermally connected to the electric control module 20 and the cooling unit 42, and includes at least one heat dissipation element 31, the heat dissipation element 31 includes a heat absorption section 33 and a heat dissipation section 34, and heat transfer can be performed between the heat absorption section 33 and the heat dissipation section 34, the heat absorption section 33 is thermally connected to the electric control module 20, and the heat dissipation section 34 is thermally connected to the cooling unit 42. The heat dissipation section 34 of the heat dissipation element 31 is thermally connected to the electric control component 21, and the heat generated by the electric control component 21 during operation can be transferred to the heat dissipation section 34 of the heat dissipation element 31, and then transferred to the heat absorption section 33 through the heat dissipation section 34, and heat exchange is performed with the refrigerant of the cooling unit 42, thereby realizing the heat dissipation function of the heat dissipation element 31.

[0060] The heat dissipation component 30 includes at least one heat dissipation element 31 , that is, the heat dissipation component 30 includes one or more heat dissipation elements 31 . Through this configuration, the heat dissipation efficiency of the heat dissipation component 30 to the electric control module 20 can be improved.

[0061] Optionally, the electric control module 20 includes an electric control component 21, the electric control component 21 includes an electric control board 22 and a plurality of components 23 disposed on the electric control board 22, the heat sink 31 includes a heat sink body 32, the heat sink body 32 is thermally connected to the electric control component 21, and the portion of the heat sink 31 thermally connected to the electric control component 21 constitutes the heat sink body 32. The heat generated by the electric control component 21 is transferred to the heat sink body 32, and the heat sink body 32 dissipates the heat, thereby dissipating the heat of the electric control module 20.

[0062] The heat dissipation component 30 includes at least one heat dissipation element 31. For example, the heat dissipation component 30 may include one heat dissipation element 31. The heat dissipation component 30 may include multiple heat dissipation elements 31. The number of heat dissipation elements 31 can be set as needed. In this way, more components 23 on the electric control board 22 can be connected to the heat dissipation element 31 through thermal conduction, so that there is a larger thermal conduction area between the heat dissipation component 30 and the electric control component 21, thereby improving the heat dissipation efficiency and heat dissipation effect of the entire electric control component 21.

[0063] The heat dissipation body 32 of at least one heat sink 31 is bent to be thermally connected to at least two components 23 of different heights. The heat dissipation body 32 of a single heat sink 31 that is bent can be thermally connected to at least two components 23 of different heights. The heat dissipation body 32 of the heat sink 31 is thermally connected to the electronic control component 21. The heat generated by the electronic control component 21 during operation can be transferred to the heat dissipation body 32 of the heat sink 31, which can reduce the temperature of the electronic control component 21 and control the temperature of the electronic control component 21 within the normal temperature, thereby realizing the heat dissipation function of the heat sink 31 to ensure the stability of the operation of the electronic control module 20.

[0064] The electronic control assembly 21 includes multiple components 23. Different components 23 have different types and sizes, and different sizes in the height direction. The heat dissipation body 32 can be thermally connected to the components 23 at different heights through a bending setting according to the different sizes of different components 23 in the height direction, thereby ensuring that multiple components 23 at different heights can fit well with the heat sink 31, while improving the heat dissipation efficiency of the components 23 and ensuring the heat dissipation effect of the components 23, thereby improving the heat dissipation effect of the entire electronic control module 20.

[0065] It should be explained that the height of the component 23 refers to the protruding height of the component 23 relative to the electric control board 22 .

[0066] The heat dissipation body 32 of at least one heat dissipation element 31 is bent, that is, one of the heat dissipation elements 31 in the heat dissipation component 30 may be bent, multiple heat dissipation elements 31 may be bent, or each heat dissipation element 31 in the heat dissipation component 30 may be bent.

[0067] At least two components 23 of different heights refer to two or more components 23 of different heights. By bending at least one heat sink 31, the heat sink 31 can be thermally connected to components 23 of different heights, thereby ensuring that each component 23 can be thermally connected to the heat sink 31, thereby improving the heat dissipation efficiency of each component 23.

[0068] By setting the heat dissipation component 30, the heat dissipation body 32 of the heat dissipation element 31 is connected to the electric control component 21 by thermal conductivity, so as to achieve heat dissipation of the electric control module 20; and the heat dissipation body 32 is set by bending, so that the same heat dissipation body 32 can be connected to the components 23 of different heights by thermal conductivity, so that the heat dissipation body 32 with a bent setting can adapt to the components 23 of different heights, so that the heat dissipation body 32 can be well fitted with the components 23 of different heights, thereby improving the heat dissipation effect of the components 23 of different heights, thereby improving the heat dissipation effect of the entire electric control module 20. In addition, the bending setting can reduce the space occupied by the heat dissipation body 32, ensuring the compact structure of the entire electric control module 20.

[0069] It should be noted that the “plurality” mentioned in the present invention refers to two or more than two.

[0070] Optionally, the end face of the component 23 in the height direction is the device end face 231. Different components 23 have different sizes in the height direction, and the heat dissipation body 32 is thermally connected to the device end face 231. Different components 23 have different sizes in the height direction, and the height positions of the device end faces 231 of components 23 of different heights are different. The heat dissipation body 32 of the heat sink 31 is arranged by bending, so that the heat dissipation body 32 of the heat sink 31 can be thermally connected to the device end faces 231 of components 23 of different heights, so that the heat dissipation body 32 of the heat sink 31 can be well fitted with the device end faces 231 of components 23 of different heights, which can ensure the heat dissipation effect of components 23 of different heights. At the same time, through this arrangement, the arrangement of the heat sink 31 inside the electric control module 20 can be facilitated, and the arrangement difficulty can be reduced. In addition, the heat sink 31 can ensure that there is a large heat conduction area between the component 23 and the heat dissipation body 32 by thermally connecting with the device end face 231, thereby ensuring the heat dissipation effect of the heat sink 31 on the component 23.

[0071] Optionally, the bent heat dissipation body 32 includes a plurality of straight sections 321 and a connecting section 322 connected between adjacent straight sections 321, an angle is formed between the straight section 321 and the connecting section 322, the angle formed between the straight section 321 and the connecting section 322 is an angle greater than zero, the straight section 321 is thermally connected to the device end face 231, and the heights of the components 23 corresponding to the plurality of straight sections 321 of the same heat dissipation body 32 are different. The straight section 321 of the heat dissipation body 32 is thermally connected to the device end face 231, so that the straight section 321 of the heat dissipation body 32 and the device end face 231 of the component 23 can be matched, so that the straight section 321 of the heat dissipation body 32 and the device end face 231 of the component 23 are well fitted, so that the heat conduction area between the heat dissipation body 32 and the device end face 231 of the component 23 is larger, and the heat dissipation efficiency of the component 23 can be improved.

[0072] The connecting section 322 of the heat dissipation body 32 is used to connect two adjacent straight sections 321. The two adjacent straight sections 321 can be connected to the components 23 at different heights by thermal conduction, so that the bending structure of the heat dissipation body 32 is relatively simple and easy to process and shape. Different straight sections 321 of the same heat dissipation body 32 correspond to components 23 at different heights, so the connecting section 322 connected between two adjacent straight sections 321 has an angle with the two adjacent straight sections 321. Through this setting, the heat dissipation body 32 can be connected to the components 23 at different heights by thermal conduction, and the heat dissipation body 32 has a simple structure and is convenient for production and processing.

[0073] For example, refer to Figure 2 and Figure 4 The heat dissipation component 30 includes two heat dissipation members 31, namely a first heat dissipation member 31a and a second heat dissipation member 31b. The heat dissipation body 32 of the first heat dissipation member 31a includes two straight sections 321 and a connecting section 322 connected between the two straight sections 321. The two straight sections 321 correspond to components 23 of two different heights.

[0074] For example, refer to Figure 8-Figure 9 The heat dissipation component 30 includes two heat dissipation members 31, namely a third heat dissipation member 31c and a fourth heat dissipation member 31d. The heat dissipation body 32 of the third heat dissipation member 31c includes three straight sections 321 and two connecting sections 322 connected between adjacent straight sections 321. The three straight sections 321 correspond to components 23 of three different heights respectively.

[0075] Optionally, the angle between the straight section 321 and the connecting section 322 is 90° to 170°. For example, the angle between the straight section 321 and the connecting section 322 may be 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc. By setting the angle between the straight section 321 and the connecting section 322 to 90°~170°, there is a larger angle between the straight section 321 and the connecting section 322, so that the bending degree of the heat dissipation body 32 is small, which is convenient for processing and manufacturing; in addition, when a heat dissipation channel 35 for the flow of heat dissipation medium is formed in the heat dissipation element 31, when the heat dissipation medium flows through the part between the straight section 321 and the connecting section 322, if the angle between the straight section 321 and the connecting section 322 is too small, it will cause greater resistance to the flow of the heat dissipation medium. By setting the angle between the straight section 321 and the connecting section 322 to 90°~170°, the resistance of the heat dissipation medium when flowing through the part between the straight section 321 and the connecting section 322 can be reduced, and the guiding effect of the connecting section 322 can be ensured, thereby ensuring that the heat dissipation medium in the heat dissipation element 31 can flow smoothly, ensuring the heat dissipation effect of the heat dissipation element 31 on the components 23, and avoiding the occurrence of poor flow of the heat dissipation medium due to the large bending degree of the heat dissipation body 32.

[0076] Optionally, the number of connecting segments 322 is 1 to 4, for example, the number of connecting segments 322 can be 1, 2, 3 or 4. The connecting segment 322 is used to connect two adjacent straight segments 321, and the two adjacent straight segments 321 can be thermally connected to components 23 of different heights, thereby reducing the number of heat sinks 31 in the heat dissipation component 30, and reducing costs to a certain extent. The number of connecting segments 322 is 1 to 4, so that the number of bending times of the heat dissipation body 32 during the processing is small, which is convenient for processing and manufacturing, and reduces the difficulty of processing and molding; and when a heat dissipation channel 35 for the flow of heat dissipation medium is formed in the heat dissipation element 31, it can ensure that the heat dissipation medium in the heat dissipation element 31 can flow smoothly, avoiding the situation where the flow path of the heat dissipation body 32 is more complicated due to too many bending times, resulting in poor flow of the heat dissipation medium, and ensuring the heat dissipation effect of the heat dissipation element 31 on the components 23.

[0077] Optionally, the height difference of the components 23 corresponding to the adjacent straight sections 321 is greater than 8mm. The heights of the multiple components 23 arranged on the electric control board 22 of the electric control module 20 are usually different. For example, the height difference of adjacent components 23 can be 1mm, 3mm, 5mm, 7mm, 9mm, 12mm, 15mm, 20mm, 30mm, etc. There are also different situations for the height difference between adjacent components 23. The height difference of some adjacent components 23 is large, and the height difference of some adjacent components 23 is small. If there is a height difference between adjacent components 23, the heat dissipation body 32 is bent to adapt to the height difference between adjacent components 23. In this way, there will be too many bending positions of the heat dissipation body 32, and the length of the connecting section 322 is too small, resulting in a large resistance to the flow of the heat dissipation medium in the heat dissipation body 32, which will significantly affect the heat dissipation effect and increase the difficulty of processing and forming the heat dissipation body 32.

[0078] Based on this, the present invention bends the heat dissipation body 32 to correspond to components 23 of different heights, while taking into account the influence of bending on the flow of the heat dissipation medium and the processing difficulty. When the height difference between adjacent components 23 is greater than 8 mm, the corresponding part of the heat dissipation body 32 is bent. This can reduce the number of bending positions of a single heat dissipation body 32, so that the length of the connecting section 322 will not be too short, which can reduce the flow resistance of the heat dissipation medium in the heat dissipation body 32, and can make the heat dissipation body 32 and the components 23 fit better. Overall, it can have a better heat dissipation effect, and the processing difficulty of the heat sink 31 is relatively low.

[0079] By making the height difference of the components 23 corresponding to adjacent straight sections 321 greater than 8 mm, the connecting section 322 between the adjacent straight sections 321 can be made to have a certain length, thereby avoiding the connection section 322 being too short, which would make the angle between the connection section 322 and the straight section 321 difficult to process, thereby reducing the difficulty of processing the heat sink 31; and when a heat dissipation channel 35 for the heat dissipation medium to flow is formed in the heat sink 31, the guiding effect of the connecting section 322 can be ensured, thereby avoiding the situation where the heat dissipation medium does not flow smoothly due to the too short connection section 322, thereby ensuring the heat dissipation effect of the heat sink 31 on the components 23.

[0080] In some embodiments of the present invention, the same straight section 321 may correspond to one component 23 , and the same straight section 321 may also correspond to at least two components 23 .

[0081] Optionally, the same straight section 321 corresponds to at least two components 23, and the height difference of the components 23 corresponding to the same straight section 321 is less than 5mm. The heights of the multiple components 23 arranged on the electric control board 22 of the electric control module 20 are usually different. For example, the height difference of adjacent components 23 can be 1mm, 3mm, 5mm, 7mm, 9mm, 12mm, 15mm, 20mm, 30mm, etc. There are also different situations for the height difference between adjacent components 23. The height difference of some adjacent components 23 is large, and the height difference of some adjacent components 23 is small. If there is a height difference between adjacent components 23, the heat dissipation body 32 is bent to adapt to the height difference between adjacent components 23. In this way, there will be too many bending positions of the heat dissipation body 32, and the length of the connecting section 322 is too small, resulting in a large resistance to the flow of the heat dissipation medium in the heat dissipation body 32, which will significantly affect the heat dissipation effect and increase the difficulty of processing and forming the heat dissipation body.

[0082] Based on this, the present invention bends the heat dissipation body 32 to correspond to components 23 of different heights, and at the same time considers the influence of bending on the flow of the heat dissipation medium and the processing difficulty. When the height difference between adjacent components 23 is less than 5 mm, the corresponding part of the heat dissipation body 32 is no longer bent, and the same straight section 321 is used to correspond to adjacent components 23 with a height difference of less than 5 mm. In this way, the number of bending positions of a single heat dissipation body 32 can be reduced, the flow resistance of the heat dissipation medium in the heat dissipation body 32 can be reduced, and the heat dissipation body 32 and the components 23 can be better fitted. Overall, it can have a better heat dissipation effect, and the processing difficulty of the heat sink 31 is relatively low.

[0083] When the height difference of different components 23 corresponding to the same heat dissipation body 32 is less than 5mm, the same straight section 321 can be connected to components 23 of different heights by heat conduction, replacing the connection method of connecting components 23 of different heights with different straight sections 321, and the structure is relatively simple; and when a heat dissipation channel 35 for the flow of heat dissipation medium is formed in the heat dissipation element 31, this arrangement can make the flow path of the heat dissipation channel 35 smoother, thereby ensuring the smoothness of the flow of the heat dissipation medium. In addition, through this arrangement, the number of bends of the heat dissipation body 32 can be reduced, the structure of the heat dissipation body 32 can be made simpler, and the production and processing difficulty of the heat dissipation element 31 can be reduced.

[0084] Among them, when the same straight section 321 corresponds to adjacent components 23 with a height difference of less than 5 mm, a thermal conductive layer can be filled between the straight section 321 and the components 23 with a lower height to compensate for the height difference, thereby achieving heat dissipation of adjacent components 23 with a height difference of less than 5 mm by the same straight section 321.

[0085] Optionally, a heat-conducting layer is provided between the straight section 321 and the device end face 231 to ensure the connection and heat-conducting effect of the heat-conducting connection between the straight section 321 and the device end face 231, further ensure that the straight section 321 and the device end face 231 are well attached, reduce the interface thermal resistance between the device end face 231 and the straight section 321, and improve the heat-conducting efficiency between the two. In addition, by providing a heat-conducting layer, when the same straight section 321 corresponds to components 23 of different heights and the height difference between the different components 23 is small, the height difference between the components 23 of different heights can be compensated by filling the heat-conducting layer, so that the same heat dissipation body 32 can use the same straight section 321 to connect components 23 of different heights, so that the structure of the heat sink 31 is simpler and convenient for production and processing.

[0086] Optionally, there may be a gap between the connecting section 322 and the component 23, and the connecting section 322 and the component 23 may also be in direct contact or thermally connected. When the connecting section 322 and the component 23 are in contact or thermally connected, the heat generated by the component 23 is also transferred to the connecting section 322 for heat dissipation. When the connecting section 322 and the component 23 are thermally connected, a thermal conductive layer may be provided between the connecting section 322 and the component 23 to achieve thermal connection between the two.

[0087] Optionally, the heat-conducting layer may include one or more of heat-conducting glue, heat-conducting silicone grease, heat-conducting pad or heat-conducting metal to ensure the heat-conducting effect of the heat-conducting layer. For example, the heat-conducting layer may be heat-conducting glue, heat-conducting silicone grease, heat-conducting pad or heat-conducting metal; the heat-conducting layer may also include at least two of heat-conducting glue, heat-conducting silicone grease, heat-conducting pad and heat-conducting metal. When the heat-conducting layer includes at least two of heat-conducting glue, heat-conducting silicone grease, heat-conducting pad and heat-conducting metal, the two heat-conducting structures may be stacked along the thickness direction of the heat-conducting layer, and the two heat-conducting structures may also be mixed with each other to form a heat-conducting layer.

[0088] In some embodiments, when the height difference between adjacent components 23 is between 5 mm and 8 mm, a single component 23 can be cooled by a single heat dissipation body 32 .

[0089] Optionally, the electric control assembly 21 includes a component group 24 corresponding to each heat sink 31, and the heat dissipation body 32 of each heat sink 31 is thermally connected to the component 23 in the corresponding component group 24. By setting the component group 24, the spatial layout inside the electric control module 20 can be regionalized and rationalized. In addition, by setting the component group 24, the components 23 of different heights can be rationally classified to facilitate the arrangement of the heat sink 31.

[0090] The component group 24 includes a first component group 241, in which the height difference between at least some of two adjacent components 23 in the first component group 241 is greater than 8 mm, and the heat dissipation body 32 thermally connected to the first component group 241 is bent. The heat dissipation body 32 thermally connected to the first component group 241 is bent so that the heat dissipation body 32 and the device end faces 231 of the components 23 at different heights in the first component group 241 can be thermally connected, thereby ensuring the heat dissipation effect of the components 23 at different heights in the first component group 241. Through this arrangement, the connecting section 322 between adjacent straight sections 321 can have a certain length, avoiding the connection section 322 being too short, which would make the angle between the connecting section 322 and the straight section 321 difficult to process. This can reduce the difficulty of processing and forming the heat sink 31. Moreover, when a heat dissipation channel 35 for the heat dissipation medium to flow is formed in the heat sink 31, the guiding effect of the connecting section 322 can be ensured, avoiding the situation where the heat dissipation medium does not flow smoothly due to the connection section 322 being too short, thereby ensuring the heat dissipation effect of the heat sink 31 on the components 23.

[0091] The height difference between at least some adjacent two components 23 in the first component group 241 is greater than 8 mm, that is, the height difference between some adjacent two components 23 may be greater than 8 mm, or the height difference between any two adjacent components 23 in the first component group 241 may be greater than 8 mm. Through this setting, the division of the area of ​​the component group 24 can be facilitated.

[0092] For example, refer to Figure 2-Figure 5 The heat dissipation component 30 includes a first heat dissipation member 31a, the electronic control component 21 includes a first component group 241, the first component group 241 includes five components 23 of two different heights, and the heat dissipation body 32 of the first heat dissipation member 31a is bent and thermally connected to the five components 23 in the first component group 241, thereby ensuring the heat dissipation effect of the components 23 of different heights.

[0093] For example, refer to Figure 8-Figure 9 The heat dissipation component 30 includes a third heat dissipation member 31c, the electronic control assembly 21 includes a first component group 241, the first component group 241 includes six components 23 of three different heights, and the heat dissipation body 32 of the third heat dissipation member 31c is bent and thermally connected to the six components 23 in the first component group 241, thereby ensuring the heat dissipation effect of the components 23 of different heights.

[0094] Optionally, the component group 24 includes a second component group 242, the height difference between each two adjacent components 23 in the second component group 242 is less than 5 mm, and the heat dissipation body 32 thermally connected to the second component group 242 is a straight structure. Through this arrangement, the height difference between each two adjacent components 23 in the second component group 242 is less than 5 mm, and the heat dissipation body 32 thermally connected to the second component group 242 does not need to be bent, which can make the structure of the heat dissipation body 32 simpler and reduce the production and processing difficulty of the heat dissipation element 31; and when a heat dissipation channel 35 for the heat dissipation medium to flow is formed in the heat dissipation element 31, the heat dissipation body 32 with a straight structure has a better flow guiding effect, and the heat dissipation medium in the heat dissipation element 31 can flow more smoothly.

[0095] The height difference between at least some of the two adjacent components 23 in the first component group 241 is greater than 8 mm, and the height difference between every two adjacent components 23 in the second component group 242 is less than 5 mm. Through this arrangement, the division of the area of ​​the component group 24 can be facilitated, thereby facilitating the arrangement of the heat sink 31.

[0096] For example, refer to Figure 2-Figure 5 The heat dissipation component 30 includes a second heat dissipation member 31b, the electronic control assembly 21 includes a second component group 242, the second component group 242 includes three components 23 of the same height, and the heat dissipation body 32 of the second heat dissipation member 31b is a flat structure, which is thermally connected to the three components 23 in the second component group 242, thereby ensuring the heat dissipation effect of the components 23.

[0097] For example, refer to Figure 8-Figure 9The heat dissipation component 30 includes a fourth heat dissipation member 31d, the electronic control assembly 21 includes a second component group 242, the second component group 242 includes a component 23, and the heat dissipation body 32 of the fourth heat dissipation member 31d is a straight structure, which is thermally connected to the component 23 in the second component group 242, thereby ensuring the heat dissipation effect of this component 23.

[0098] Optionally, the electronic control assembly 21 includes component groups 24 corresponding to each heat sink 31, and at least two component groups 24 have different powers or different widths, and the widths of the heat sink bodies 32 corresponding to the component groups 24 with different powers or different widths are different. The widths of the heat sink bodies 32 corresponding to the component groups 24 with different powers or widths are different, and the widths of the heat sink bodies 32 corresponding to the component groups 24 with different powers or widths are different. Through this setting, it is possible to ensure that the components 23 with different powers or widths in the component group 24 have sufficient contact areas with the corresponding heat sink bodies 32, thereby ensuring that there is sufficient heat conduction area between different components 23 and the heat sink bodies 32, so as to improve the heat dissipation efficiency of the components 23.

[0099] Optionally, the width of the heat dissipation body 32 can be the same as the width of the corresponding component group 24, or the width of the heat dissipation body 32 can be slightly larger than the width of the corresponding component group 24, ensuring that there is sufficient heat conduction area between the component 23 and the heat dissipation body 32 while controlling the width of the heat dissipation body 32, thereby avoiding the situation where the cost of the heat sink 31 is higher due to the width of the heat dissipation body 32 being larger than the width of the component group 24.

[0100] For example, refer to Figure 2-Figure 5 as well as Figure 8-Figure 9 There are two heat sinks 31 in the heat dissipation component 30, and there are two component groups 24 in the electronic control assembly 21. The widths of the two component groups 24 are different, and the widths of the heat dissipation bodies 32 respectively thermally connected to the two component groups 24 are also different.

[0101] For example, the components 23 may include capacitors, common-mode inductors, fan control components for controlling the outdoor fan 11, compressor control components for controlling the compressor assembly 12, and PFC components. Among them, the fan control components, compressor control components, and PFC components have higher power than other components 23, and the temperature rises faster during operation. The heat dissipation body 32 connected thereto can be set to a larger width to increase the heat conduction area between the heat dissipation body 32 and the components 23, and improve the heat dissipation effect of the components 23. Compared with other components 23, capacitors and common-mode inductors have lower power, and the temperature rises relatively slowly during operation. The heat dissipation body 32 connected thereto can be set to a smaller width to reduce the cost of the heat sink 31.

[0102] Optionally, the heat dissipation body 32 is formed in a flat shape, and at least one side of the heat dissipation body 32 in the thickness direction is thermally connected to the component 23. At least one side of the heat dissipation body 32 in the thickness direction is thermally connected to the component 23, that is, one side of the heat dissipation body 32 in the thickness direction is thermally connected to the component 23, or both sides of the heat dissipation body 32 in the thickness direction are thermally connected to the component 23. The flat heat dissipation body 32 has a larger contact surface with the component 23, so that the heat conduction area between the component 23 and the heat dissipation body 32 can be greatly increased, thereby improving the heat dissipation effect of the component 23. In addition, the flat heat dissipation body 32 can greatly reduce the space occupancy of the heat sink 31.

[0103] Optionally, the heat dissipation body 32 is connected to the electric control board 22 via a first fastener 26. This connection method can ensure the connection effect between the heat dissipation body 32 and the electric control board 22, and at the same time, the connection process is simple, which can facilitate the assembly and disassembly of the heat dissipation body 32 and the electric control board 22. Among them, the first fastener 26 can be a threaded fastener, and the heat dissipation body 32 and the electric control board 22 are threadedly connected via the first fastener, which is reliable and convenient for assembly and disassembly.

[0104] Reference Figure 1 According to some embodiments of the present invention, the heat dissipation component 30 further includes a heat conductive member 38, and the heat dissipation section 34 and the cooling portion 42 are heat-conductively connected via the heat conductive member 38; the heat conductive member 38 includes a heat conductive substrate 381, and the heat dissipation section 34 and the cooling portion are located on opposite sides of the thickness direction of the heat conductive substrate 381. By providing the heat conductive member 38, the connection effect and heat conduction effect between the heat dissipation section 34 and the cooling portion 42 can be ensured, thereby improving the heat dissipation efficiency of the cooling portion 42 to the heat dissipation section 34. In addition, by providing the heat conductive substrate 381, the connection between the heat dissipation section 34 and the cooling portion 42 can be facilitated. At the same time, this arrangement can make the arrangement of the heat dissipation section 34, the cooling portion 42 and the heat conductive substrate 381 more compact, thereby improving the space utilization rate.

[0105] Optionally, the heat dissipation section 34 is formed in a flat shape, and the heat dissipation section 34 and the heat conductive substrate 381 are overlapped in the thickness direction of the heat conductive substrate 381. Through this arrangement, the flat heat dissipation section 34 can greatly increase the contact area between the heat dissipation section 34 and the heat conductive substrate 381, thereby increasing the heat conduction area between the heat dissipation section 34 and the heat conductive substrate 381, and improving the heat dissipation efficiency of the cooling unit 42 to the heat dissipation section 34. At the same time, this arrangement can make full use of the internal space of the outdoor unit 100 and improve the space utilization rate.

[0106] Optionally, the heat dissipation section 34 is connected to the heat conductor 38 by welding or by a second fastener, which can ensure the connection effect between the heat dissipation section 34 and the heat conductor 38 and avoid the heat dissipation section 34 and the heat conductor 38 being separated due to vibration during the operation of the outdoor unit 100.

[0107] Optionally, the cooling part 42 is connected to the heat conductor 38 by welding, which can ensure the connection effect between the cooling part 42 and the heat conductor 38 and avoid the cooling part 42 and the heat conductor 38 being separated due to vibration during the operation of the outdoor unit 100.

[0108] Optionally, the cooling portion 42 may be disposed on one side of the heat conducting member 38 in the thickness direction and arranged in an “S” shape, so as to increase the contact area between the cooling portion 42 and the heat conducting member 38 , thereby improving the heat transfer effect.

[0109] Reference Figure 8-Figure 9 According to some embodiments of the present invention, the outdoor unit 100 further includes a heat dissipation component 30, the heat dissipation component 30 includes at least one heat dissipation element 31, the electric control module 20 includes an electric control component 21, the heat dissipation element 31 is thermally connected to the electric control component 21, a heat dissipation channel 35 for the flow of heat dissipation medium is formed in the heat dissipation element 31, and at least part of the cooling part 42 constitutes the heat dissipation component 30. The heat dissipation medium can absorb the heat generated by the components 23 during operation by flowing in the heat dissipation channel 35, thereby realizing the heat dissipation function of the heat dissipation component 30 and achieving a better heat dissipation effect.

[0110] The heat dissipation component 30 includes at least one heat dissipation element 31 , that is, the heat dissipation component 30 includes one or more heat dissipation elements 31 . Through this configuration, the heat dissipation efficiency of the heat dissipation component 30 to the electric control module 20 can be improved.

[0111] At least a portion of the cooling portion 42 constitutes the heat dissipation component 30 , that is, a portion of the cooling portion 42 may constitute the heat dissipation component 30 , or the entire cooling portion 42 may constitute the heat dissipation component 30 .

[0112] Optionally, the heat sink 31 is a phase change heat sink element and includes a heat absorbing section 33 and a heat dissipating section 34. The heat dissipating medium in the heat sink 31 is suitable for circulating between the heat absorbing section 33 and the heat dissipating section 34. The heat absorbing section 33 includes a heat dissipating body 32. The heat absorbing section 33 of the heat sink 31 is used to absorb the heat generated by the components 23 during operation to achieve the heat dissipation function of the components 23. The heat dissipating section 34 of the heat sink 31 is used to dissipate the heat of the heat dissipating medium, so that the heat dissipating medium can flow to the heat dissipating section 34 again to absorb heat after the heat dissipation is completed, thereby achieving the circulation of the heat dissipating medium between the heat absorbing section 33 and the heat dissipating section 34.

[0113] During the operation of the heat sink 31, the heat dissipation medium located in the heat absorption section 33 is in a liquid state. After the liquid heat dissipation medium absorbs the heat generated during the operation of the component 23, it will be converted from liquid to gas and flow to the heat dissipation section 34 through the heat dissipation channel 35. The gaseous heat dissipation medium condenses in the heat dissipation section 34, and is converted from a high-temperature gas to a low-temperature liquid again. Finally, it flows to the heat absorption section 33 through the heat dissipation channel 35, and absorbs the heat generated during the operation of the component 23 again, and performs the next heat dissipation cycle.

In addition, the plurality of heat sinks 31 arranged in parallel can dissipate heat more evenly for the components 23, thereby further improving the heat dissipation effect.

The heat dissipation medium enters the heat dissipation channel 35 of the third heat dissipation component 31c and the fourth heat dissipation component 31d from the medium inlet pipe 36, and absorbs the heat generated by the components 23 that are respectively thermally connected to the heat dissipation bodies 32 of the third heat dissipation component 31c and the fourth heat dissipation component 31d during the working process.

In addition, the heat dissipation section 34 is arranged outside the electric control box body 25, so that the heat of the heat dissipation medium located in the heat dissipation section 34 can be dissipated in time, thereby ensuring the heat dissipation effect of the next heat dissipation cycle.

At the same time, the condensation phenomenon caused by cooling the electronic control module 20 with the refrigerant can be reduced or avoided, thereby improving the safety of the entire machine.

[0125] Refer to the following Figure 1-Figure 7 The outdoor unit 100 according to some embodiments of the present invention is described.

[0126] Reference Figure 1-Figure 7 In this embodiment, the outdoor unit 100 is an air-conditioning outdoor unit 100, and the air-conditioning outdoor unit 100 includes an outdoor housing 10, an outdoor heat exchanger, an outdoor fan 11, a compressor assembly 12, an electronic control module 20, a heat exchange component, a refrigerant circulation system, a throttling component 46, a flow regulating device 45, and a water-path heat exchange component.
