[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0021] Hereinafter, with reference to the accompanying drawings, a heat exchange component 1 according to an embodiment of the present invention will be described.

[0022] like Figures 1-6 As shown, the heat exchange component 1 according to the embodiment of the present utility model includes a heat exchanger 11 and a cooling plate 14. The heat exchanger 11 includes a plurality of heat exchange plates 117 stacked together, and the plurality of heat exchange plates 117 form heat exchange channels 118. The cooling plate 14 is disposed on the heat exchanger 11 and forms a refrigerant channel. The refrigerant channel communicates with the heat exchange channel 118. The cooling plate 14 is used for heat exchange connection with electronic components.

[0023] In the above embodiment, by setting a cooling plate 14, the cooling plate 14 forms a refrigerant channel and the refrigerant channel is connected to the heat exchange channel 118, so that the refrigerant in the heat exchange channel 118 can enter the refrigerant channel to remove the heat transferred from the electronic components to the cooling plate 14, thereby achieving the purpose of cooling the electronic components.

[0024] Meanwhile, in this embodiment, the cooling plate 14 is integrated into the heat exchanger 11, eliminating the need for additional refrigerant pipes to connect the cooling plate 14 and the heat exchanger 11. This reduces the space occupied by the heat exchange component 1, making its installation more convenient, and also reduces the probability of refrigerant leakage, thereby improving the reliability of the heat exchange component 1.

[0025] Specifically, the cooling plate 14 is disposed on the heat exchanger 11. For example, the cooling plate 14 can be welded to the heat exchange fins 117 or connected by fasteners.

[0026] like Figures 5-6As shown, the heat exchange component 1 includes a heat exchanger 11. The heat exchanger 11 has at least two independent and mutually heat-exchanging first flow channels 111 and second flow channels 112. Refrigerant flows through the first flow channels 111 and second flow channels 112 respectively. The refrigerant in different flow channels can exchange heat, but they do not flow into each other to achieve independence. For example, along the stacking direction F1, at least a portion of the first flow channel 111 is defined by a gap between the first and second heat exchange plates, and at least a portion of the second flow channel 112 is defined by a gap between the second and third heat exchange plates.

[0027] The refrigerant channel is connected to the heat exchange channel 118. For example, the refrigerant channel can be connected to the first channel 111, or the refrigerant channel can be connected to the second channel 112. As long as the temperature of the refrigerant entering the heat exchange plate 117 is low, heat exchange with the electronic components can be achieved to cool the electronic components. By directly supplying refrigerant to the cooling plate 14 to exchange heat with the electronic components, the energy transfer path is short and the heat exchange efficiency is high.

[0028] The cooling plate 14 may include a first opening 142 and a second opening 143, both of which are connected to a refrigerant channel. The heat exchange plate 117 is formed with a third opening and a fourth opening, the third opening being connected to the first opening 142 and the fourth opening being connected to the second opening 143.

[0029] Alternatively, the cooling plate 14 is formed with an opening, and the heat exchange fins 117 adjacent to the cooling plate 14 are covered by the opening. The heat exchange fins 117 are formed with a third opening and a fourth opening, both of which are opposite to the opening, so that the refrigerant in the heat exchange fins 117 can enter the cooling plate 14.

[0030] Alternatively, the heat exchange fin 117 closest to the cooling plate 14 may have a third opening, which serves as the flow port of the heat exchange channel. One of the first opening 142 and the second opening 143 may be connected to the third opening, and the other of the first opening 142 and the second opening 143 may be used to discharge refrigerant to the outside of the heat exchange component 1 or to inject refrigerant into the heat exchange component 1.

[0031] In some embodiments of this utility model, reference can be made to Figure 4 The cooling plate 14 has a cooling cavity 141 that communicates with the refrigerant channel. The cooling cavity 141 is connected to the heat exchange channel 118 through the refrigerant channel. The volume of the cooling cavity 141 is larger than the volume of the space between two adjacent heat exchange plates 117. Along the stacking direction F1, that is, the stacking direction F1 of the heat exchange plates 117, the size H2 of the cooling cavity 141 is larger than the size H1 of the space between the two heat exchange plates 117.

[0032] The volume of the cooling chamber 141 is larger than the volume of the space between two adjacent heat exchange plates 117, so that the cooling chamber 141 can hold enough refrigerant to meet the large heat exchange demand and achieve a better cooling effect for electronic components.

[0033] For example, along the stacking direction F1, the size of the cooling cavity 141 can be 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20 times the size of the space between the two heat exchange fins 117, etc., without specific limitations.

[0034] Along the stacking direction F1, the size of the cooling cavity 141 is larger than the size of the space between the two heat exchange plates 117, so that the volume of the cooling cavity 141 is larger than the volume of the space between the two adjacent heat exchange plates 117. This allows the cooling cavity 141 to hold a sufficient amount of refrigerant to meet the large heat exchange demand and achieve a better cooling effect for electronic components. At the same time, in the stacking direction F1 perpendicular to the heat exchange plates 117, the cooling plate 14 does not occupy too much space; the flow resistance of the refrigerant in the cooling cavity 141 is also small.

[0035] In some embodiments of this utility model, the cooling plate 14 has a cooling cavity 141 communicating with a refrigerant channel. The cooling cavity 141 is connected to the heat exchange channel 118 through the refrigerant channel. The volume of the cooling cavity 141 is larger than the volume of the space between two adjacent heat exchange plates 117. Along the direction perpendicular to the stacking direction F1, the size of the cooling plate 14 is not smaller than the size of the heat exchange plate 117. Here, refer to... Figure 1 and Figure 4 Along the direction perpendicular to the stacking direction F1, it can refer to either the length direction F2 of the heat exchanger 117 or the width direction F3 of the heat exchanger 117. For example, along the length direction F2 of the heat exchanger 117, the dimension L2 of the cooling plate 14 can be equal to or larger than the dimension L1 of the heat exchanger 117; see reference. Figure 1 and Figure 3 Along the width direction F3 of the heat exchange fin 117, the dimension D2 of the cooling plate 14 can be equal to or greater than the dimension D1 of the heat exchange fin 117. Furthermore, the dimensions of the cooling plate 14 can be the same or different at various points.

[0036] Along the direction perpendicular to the stacking direction F1, the size of the cooling plate 14 is not smaller than the size of the heat exchange plate 117. On the one hand, this ensures that the volume of the cooling cavity 141 is not less than the volume of the space between two adjacent heat exchange plates 117, thereby allowing the cooling cavity 141 to hold a sufficient amount of refrigerant to meet the large heat exchange demand and achieve a better cooling effect for the electronic components. On the other hand, it also allows the heat exchange area of ​​the cooling plate 14 to be large enough to contact and exchange heat with as many electronic components as possible or with multiple electronic components that are far apart. At the same time, it also provides a better support effect for the heat exchanger 11.

[0037] In some embodiments of this utility model, reference can be made to Figure 5 , Figure 6 as well as Figure 9 The heat exchange channel 118 includes a first channel 111 and a second channel 112 connected by heat exchange. The first channel 111 has a first channel opening 113 and a second channel opening 114, and the second channel 112 has a third channel opening 115 and a fourth channel opening 116. The first channel 111 and the second channel 112 are independent of each other but can exchange heat with each other. The spaces between multiple adjacent heat exchange plates 117 are interconnected to form the first channel 111, and the spaces between multiple adjacent heat exchange plates 117 are interconnected to form the second channel 112.

[0038] The cooling plate 14 has a first opening 142 and a second opening 143, both of which are connected to a refrigerant channel. One of the first flow channel 113 and the second flow channel 114 is connected to the first opening 142. The second opening 143 forms the first interface of the heat exchange component 1, wherein the refrigerant can enter the heat exchange component 1 from the first interface or flow out of the heat exchange component 1 from the first interface.

[0039] In other words, the refrigerant can first flow completely through the first flow channel 111, then enter the cooling chamber 141 of the cooling plate 14, and then flow out of the heat exchange component 1; or, the refrigerant can first enter the cooling chamber 141 of the cooling plate 14, and then flow completely through the first flow channel 111.

[0040] This allows the refrigerant to flow through the space between multiple heat exchange plates 117 as much as possible, reducing the possibility that the refrigerant will flow out after only passing directly through the cooling plate 14, so that the heat exchanger 11 has a better heat exchange effect.

[0041] In some embodiments of this utility model, reference can be made to Figures 2 to 4A mounting member 200 is provided on one side 145 of the cooling plate 14 facing away from the heat exchanger 11 along the stacking direction F1. The mounting member 200 is configured to install the heat exchange component 1. The side 144 of the cooling plate 14 perpendicular to the stacking direction F1 is used for heat exchange connection with electronic components. Therefore, the installation of the heat exchange component 1 will not affect the installation of the electronic components, and the clamping force between the heat exchange component 1 and the electronic components can be easily controlled, making it less likely to damage the electronic components.

[0042] In other words, the heat exchange component 1 can be mounted on the carrier component via the mounting component 200. For example, the heating and cooling regulating device 1000 includes a carrier component, which is plate-shaped and extends vertically. The carrier component is used to support the heat exchange component 1 to realize the installation of the heat exchange component 1.

[0043] For example, the mounting member 200 is a threaded post 201, and the carrier member has a through hole. The threaded post 201 passes through the through hole and is locked with a nut located on the side of the carrier member away from the heat exchanger 11.

[0044] In some embodiments of this invention, the side 145 of the cooling plate 14 facing away from the heat exchanger 11 along the stacking direction F1 is used for heat exchange with electronic components. In this way, the area of ​​the cooling plate 14 available for heat exchange is large, allowing it to be connected to a large number of electronic components for heat exchange, and also achieving better heat dissipation for multiple electronic components that are arranged far apart.

[0045] In some embodiments of this utility model, the heating and cooling regulating device 1000 includes a carrier component for supporting the heat exchange component 1 and a mounting frame. The mounting frame includes a frame body, a mounting part, and a snap-fit ​​part. Both the mounting part and the snap-fit ​​part are disposed on the frame body. The mounting part connects the frame body and the carrier component, and the snap-fit ​​part snaps into the heat exchange component 1. For example, the snap-fit ​​part can snap into the heat exchanger 11, or the snap-fit ​​part can snap into the cooling plate 14.

[0046] For example, in an embodiment where the cooling plate 14 is located on one side 145 away from the heat exchanger 11 along the stacking direction F1 for heat exchange with electronic components, the heat exchange component 1 can be mounted on the carrier component by a mounting bracket.

[0047] In some embodiments of this utility model, the heat exchange plate 117 and the cooling plate 14 are made of the same material.

[0048] For example, the heat exchange fins 117 and the cooling plate 14 are both made of stainless steel, or the heat exchange fins 117 and the cooling plate 14 are both made of copper.

[0049] The heat exchange fins 117 and the cooling plate 14 are made of the same material, which allows for better welding of the heat exchange fins 117 and the cooling plate 14, and also extends the service life of the heat exchange component 1 and makes it less prone to oxidation and corrosion.

[0050] In some embodiments of this utility model, such as Figures 1 to 4 The heat exchange component 1 also includes a valve island assembly, which is disposed on the heat exchanger 11 and includes a valve island body 13 and a throttling device 12. The valve island body 13 forms a first flow path, a second flow path, a first port 1321, a second port 1322 and a third port 1323. The first port 1321 and the third port 1323 are respectively formed at both ends of the first flow path, and the second port 1322 is formed at one end of the second flow path. The other end of the second flow path is connected to the first flow path. The first port 1321 is connected to the first flow channel 111, and the second port 1322 is connected to the second flow channel 112. The throttling device 12 is disposed on the valve island body 13 and located in the second flow path. The third port 1323 forms the second interface of the heat exchange component 1. The cooling plate 14 and the valve island assembly are respectively disposed on two opposite sides of the heat exchanger 11 along the stacking direction F1.

[0051] For example, the valve island assembly is disposed on the heat exchanger 11. The valve island assembly can be welded to the heat exchanger 11. The valve island assembly includes a valve island body 13 and a throttling device 12. The valve island body 13 is constructed in a tubular shape and has a first port 1321, a second port 1322 and a third port 1323.

[0052] You can refer to Figure 11 When the heating and cooling control device 1000 switches to cooling mode, the compressor 4 can send the compressed refrigerant into the outdoor heat exchanger 3. The compressed refrigerant releases heat in the outdoor heat exchanger 3, and the refrigerant after releasing heat can flow into the valve island body 13 through the third port 1323. Part of the refrigerant flowing into the valve island body 13 can flow into the first flow channel 111 through the first port 1321 and flow into the indoor heat exchanger 2 along the first flow channel 111. The refrigerant expands and absorbs heat in the indoor heat exchanger 2 to achieve cooling. The refrigerant after absorbing heat can flow back into the compressor 4. Another part of the refrigerant flowing into the valve island body 13 can flow into the second flow channel 112 through the throttling device 12, and expand and absorb heat in the second flow channel 112 to reduce the temperature of the refrigerant in the first flow channel 111, improve the cooling effect of the refrigerant in the indoor heat exchanger 2, and the refrigerant in the second flow channel 112 can flow back into the compressor 4 after absorbing heat.

[0053] When the heating / cooling control device 1000 switches to heating mode, the compressor 4 can send the compressed refrigerant into the indoor heat exchanger 2. The compressed refrigerant releases heat in the indoor heat exchanger 2 to achieve the heating function. The refrigerant after releasing heat flows into the valve island body 13 along the first flow channel 111. Part of the refrigerant flowing into the valve island body 13 can flow into the outdoor heat exchanger 3 through the third port 1323 and expand to absorb heat, so as to flow back into the compressor 4 after absorbing heat. The other part of the refrigerant flowing into the valve island body 13 can flow into the second flow channel 112 through the throttling device 12 and expand to absorb heat in the second flow channel 112 to reduce the temperature of the refrigerant in the first flow channel 111, improve the heat absorption efficiency of the refrigerant in the outdoor heat exchanger 3, and the refrigerant flowing into the second flow channel 112 can flow back into the compressor 4 after absorbing heat.

[0054] Understandably, by mounting the valve island assembly directly onto the heat exchanger 11, there is no need to install additional refrigerant pipes to connect the valve island assembly and the heat exchanger 11. This allows for an integrated design, reduces the space occupied by the heat exchange component 1, lowers processing costs, and simplifies the installation process of the heat exchange component 1 due to the reduced number of parts. It also reduces the probability of refrigerant leakage.

[0055] The cooling plate 14 and the valve island assembly are respectively located on opposite sides of the heat exchanger 11 along the stacking direction F1. That is to say, both the cooling plate 14 and the valve island assembly are integrated into the heat exchanger 11, further increasing the integration of the refrigerant circulation system 100, reducing the space occupied by the heat exchange components 1, and reducing the installation complexity of the heat exchange components 1. At the same time, the cooling plate 14 has a simple structure and is easy to process and shape.

[0056] In some embodiments of this utility model, the cooling plate 14 is connected between the first port 1321 and the first flow channel opening 113 of the first flow channel 111.

[0057] For example, you can refer to Figure 5 In cooling mode, the refrigerant sequentially enters the cooling chamber 141 of the cooling plate 14 through the third port 1323, the first port 1321, and the first opening 142, then flows into the first flow channel 111 through the first flow channel opening 113, and finally flows out of the first flow channel 111 from the second flow channel opening 114. (See reference...) Figure 6 In heating mode, the refrigerant discharged from the indoor heat exchanger 2 flows into the first channel 111 through the second channel port 114, then flows out from the first channel port 113 of the first channel 111, then flows into the cooling chamber 141 of the cooling plate 14 through the first opening 142, and finally flows out from the second opening 143.

[0058] In this way, the refrigerant temperature in the cooling cavity 141 of the cooling plate 14 is relatively low, which can achieve a better heat dissipation effect for electronic components.

[0059] In some embodiments, the side of the cooling plate 14 used for heat exchange with electronic components is a first side, and the side with the second opening 143 is a second side. The first side and the second side are different sides of the cooling plate 14.

[0060] In some embodiments of this utility model, reference can be made to Figures 5 to 8 The throttling device 12 includes a capillary sprue element 121 and an electronic expansion valve 122 arranged sequentially along the direction from the second port 1322 to the second flow channel 112. That is, the throttling device 12 includes a capillary sprue element 121 and an electronic expansion valve 122, which are arranged sequentially along the direction from the second port 1322 to the second flow channel 112.

[0061] Specifically, the second port 1322, the capillary sprue element 121, the electronic expansion valve 122, and the second flow channel 112 can be connected sequentially; or, the second port 1322, the electronic expansion valve 122, the capillary sprue element 121, and the second flow channel 112 can be connected sequentially, and this utility model does not impose any limitations on this. Thus, the refrigerant flowing to the second flow channel 112 can be doubly throttled, ensuring the throttling effect of the throttling device 12.

[0062] The second aspect of this utility model also proposes a heating and cooling regulation device 1000.

[0063] You can refer to Figures 10 to 12 As shown, the heating and cooling regulating device 1000 according to an embodiment of the present invention includes a refrigerant circulation system 100 and electronic components. The refrigerant circulation system 100 includes a heat exchange component 1 according to any of the above embodiments. It should be noted that the heating and cooling regulating device 1000 can be an air conditioner, a water heater, or other devices equipped with a refrigerant circulation system 100, and the present invention does not limit this.

[0064] According to the embodiment of the present invention, the heating and cooling regulating device 1000 includes a cooling plate 14 with a refrigerant channel that communicates with a heat exchange channel 118. This allows the refrigerant in the heat exchange channel 118 to enter the refrigerant channel, carrying away the heat transferred from the electronic components to the cooling plate 14, thus cooling the electronic components. Furthermore, this embodiment integrates the cooling plate 14 into the heat exchanger 11, eliminating the need for additional refrigerant pipes connecting the cooling plate 14 and the heat exchanger 11. This reduces the space occupied by the heat exchange component 1, making its installation more convenient, lowering the probability of refrigerant leakage, and improving the reliability of the heat exchange component 1.

[0065] In some embodiments of this utility model, the heat exchange component 1 includes a first interface, a second interface, and a third interface. For example, a second flow channel 114 is formed as the first interface of the heat exchange component 1, a valve island body 13 defines the second interface of the heat exchange component 1, and a fourth flow channel 116 is formed as the third interface of the heat exchange component 1.

[0066] You can refer to Figure 11 and Figure 12 The refrigerant circulation system 100 also includes a reversing valve 5, a compressor 4, an indoor heat exchanger 2, and an outdoor heat exchanger 3. The reversing valve 5 includes a D valve port, an E valve port, an S valve port, and a C valve port. The discharge port of the compressor 4 is connected to the D valve port, and the suction port of the compressor 4 is connected to the S valve port. One end of the indoor heat exchanger 2 is connected to the E valve port, and the other end of the indoor heat exchanger 2 is connected to the first interface. One end of the outdoor heat exchanger 3 is connected to the C valve port, and the other end of the outdoor heat exchanger 3 is connected to the second interface. The suction port of the compressor 4 is connected to the third interface. The reversing valve 5 switches one of the E valve port and the C valve port to be connected to the D valve port and the other to be connected to the S valve port.

[0067] Specifically, such as Figure 11 As shown, when the heating and cooling control device 1000 switches to cooling mode, valve ports C and D are connected, and valve ports E and S are connected. The discharge port of compressor 4 can send the compressed refrigerant into the outdoor heat exchanger 3 through the reversing valve 5. The compressed refrigerant releases heat in the outdoor heat exchanger 3, and the refrigerant after releasing heat flows through the throttling device 6 into the valve island body 13. Part of the refrigerant flowing into the valve island body 13 flows into the cooling chamber 141 of the cooling plate 14 through the second opening 143, then flows into the first flow channel 111 through the first port 1321, and finally is discharged into the indoor heat exchanger 2 through the second flow channel opening 114. The refrigerant flowing into the indoor heat exchanger 2 absorbs heat and expands to achieve cooling. After absorbing heat, the refrigerant can flow to the suction port of the compressor 4 through the reversing valve 5. Another part of the refrigerant flowing into the valve island body 13 can flow through the second port 1322, the capillary flow element 121, the electronic expansion valve 122, and the third flow channel opening 115 to flow into the second flow channel 112, and expand and absorb heat in the second flow channel 112 to cool down the refrigerant in the first flow channel 111, thereby improving the cooling effect of the refrigerant in the indoor heat exchanger 2. The refrigerant in the second flow channel 112 can flow to the suction port of the compressor 4 after absorbing heat.

[0068] like Figure 12As shown, when the heating / cooling regulating device 1000 switches to heating mode, valve ports C and S are connected, and valve ports E and D are connected. The compressor 4 can send the compressed refrigerant into the indoor heat exchanger 2 via the reversing valve 5. The compressed refrigerant releases heat in the indoor heat exchanger 2 to achieve heating. The refrigerant after heat release can enter the first flow channel 111 of the heat exchanger 11 through the second flow channel port 114, then flow into the cooling chamber 141 of the cooling plate 14 through the first opening 142, and after flowing out of the cooling plate 14, it flows into the outdoor heat exchanger 3. The refrigerant flowing into the outdoor heat exchanger 3 expands and absorbs heat. The refrigerant after absorbing heat flows through the reversing valve 5 to... The compressor 4's suction inlet; another portion of the refrigerant flowing out of the cooling plate 14 can flow through the second port 1322, capillary flow element 121, electronic expansion valve 122, and third flow channel port 115 to flow into the second flow channel 112, where it expands and absorbs heat to cool the refrigerant in the first flow channel 111, thereby improving the heat absorption efficiency of the refrigerant in the outdoor heat exchanger 3. The refrigerant in the second flow channel 112 can also flow to the compressor 4's suction inlet through the reversing valve 5 after absorbing heat.

[0069] Understandably, the refrigerant circulation system 100 has a high degree of integration, occupies little space, is easy to arrange, has few components, is easy to assemble, and is highly practical, thus improving the practicality of the cooling and heating regulation device 1000.
