[0028] like Figures 1-8As shown, the heat exchange component 1 according to an embodiment of the present invention includes a first part 11, a second part 12 and a third part 13. The first part 11 has a first interface 111 and a second interface 112. It can be understood that the first interface 111 can be set to multiple and the second interface 112 can also be set to multiple. In this embodiment, the first interface 111 is an inlet and the second interface 112 is an outlet. When the heat exchange component 1 is in working state, liquid refrigerant flows into the heat exchange component 1 from the inlet, and the electronic components connected to the heat exchange component 1 generate heat when powered on. The liquid refrigerant inside the evaporator absorbs the heat generated by the electronic components, evaporates into gaseous refrigerant, and is discharged from the second interface 112.
[0029] like Figures 1 to 8 The heat exchange assembly 1 shown, in some practical applications, is combined with a condenser as an important component of a radiator, and can be used to dissipate heat and cool electronic devices. There are many ways to install electronic devices. Usually, fasteners such as bolts are used to install the electronic device on one of the wide sides of the heat exchange assembly 1. The heat exchange assembly 1 is formed by a plurality of plates that are stacked and fixedly connected. The fixing processing method is not limited to welding. One of the first piece 11 and the second piece 12 serves as a base plate, and the other piece serves as a cover plate. The first interface 111 can be set on the first piece 11 or the second piece 12, and the second interface 112 can also be set on the first piece 11 or the second piece 12 according to the installation environment and requirements. In order to enable the liquid refrigerant to flow into the interior of the heat exchange assembly 1 and circulate inside, other plates are also provided in the first piece 11 and the second piece 12, and the other plates are mostly hollow structures.
[0030] The heat exchange assembly 1 includes a first piece 11, a second piece 12, a third piece 13 and a fourth piece 14. The first piece 11 is provided with a first interface 111 and a second interface 112. Figure 1 In the x direction shown in the figure, the first interface 111 is located below the second interface 112, and the third part 13 includes a plurality of flow channels, and the plurality of flow channels include a first flow channel 133 and a second flow channel 134. The first flow channel 133 is connected to the first interface 111, and the second flow channel 134 is connected to the second interface 112. It can be understood that the number of the first interface 111 and the second interface 112 is related to actual needs and is only for illustrative purposes and does not represent any limitation.
[0031] Specifically, if Figure 1The heat exchange component 1 shown in the figure has a third part 13 and a fourth part 14 between the first part 11 and the second part 12. The first part 11 and the second part 12 serve as the bottom plate and the cover plate of the heat exchange component 1. The first interface 111 and the second interface 112 are both provided on the first part 11. The electronic device (not shown in the figure) can be provided on the side of the second part 12. Usually, the interfaces are provided on the same fastener to facilitate production, processing and installation. There are two first interfaces 111 and two second interfaces 112. In the height direction of the heat exchange component, the first interface 111 is lower than the second interface 112. The first interface 111 serves as the inlet of the liquid refrigerant and the second interface 112 serves as the outlet of the gaseous refrigerant. The third part 13 includes The first sub-component 131 and the second sub-component 132, the first sub-component 131 has a first cavity 130, it can also be understood that the first sub-component 131 serves as a frame, the first sub-component 131 has multiple inner walls, the second sub-component 132 is located in the first cavity 130, the number of second sub-components 132 can be two or more, one end of the second sub-component 132 in the length direction is connected to an inner wall in the length direction of the first sub-component 131, the other end of the second sub-component 132 in the length direction is connected to another inner wall in the length direction of the first sub-component 131, there is a gap between one side of the second sub-component 132 in the width direction and the inner wall of the first sub-component 131, thereby forming a first flow channel 133 and a second flow channel 134.
[0032] The fourth component 14 includes a third sub-component 141 and multiple fourth sub-components 142. The third sub-component 141 has a second cavity 140. It can be understood that the third sub-component 141 serves as a frame, and the fourth sub-component 142 is located in the second cavity 140. Multiple fourth sub-components 142 are spaced apart in the length direction of the heat exchange component 1. The third sub-component 141 has a first wall and a second wall in the width direction of the third sub-component 141. The first wall and the second wall refer to the inner wall of the third component. There are multiple fourth sub-components 142. The fourth sub-component 142 includes a first end and a second end in the height direction of the heat exchange component. The first end of some fourth sub-components 142 is connected to the first wall, and the second end is a free end. There is a gap between the free end of the fourth sub-component 142 and the second wall.
[0033] In the length direction of the heat exchange component 1, there is a third flow channel 143 between two adjacent fourth sub-components 142, and the first flow channel 133 is in the length direction of the heat exchange component 1 ( Figure 1As shown in the y direction, in the height direction of the heat exchange component 1, the first flow channel 133 is close to the bottom of the heat exchange component 1, and the liquid refrigerant flows in from the first interface 111 and into the first flow channel 133. A part of it flows into the gap formed by the end of the fourth sub-component 142 and the inner wall of the third sub-component 141, and another part flows along the extension direction of the first flow channel 133, diverting the liquid refrigerant to the remaining more third flow channels 143. From then on, the liquid refrigerant can cover the entire bottom of the heat exchange component 1 along the extension direction of the first flow channel 133.
[0034] The liquid refrigerant at the bottom absorbs the heat generated by the electronic devices and vaporizes, thereby reducing the temperature of the electronic devices. Furthermore, the vaporized refrigerant can be discharged from the flow channel at the top of the heat exchange component 1. Since part of the third sub-component 141 is connected to the second wall, the gaseous refrigerant at the top of this part is also discharged through the second flow channel 134.
[0035] In some embodiments, as Figure 1 As shown, multiple third sub-components 141 can be divided into two or more groups, wherein the fourth sub-components 142 of one group connect the same end in the height direction of the heat exchange component 1 to the first wall of the third sub-component 141, and the fourth sub-components 142 of the other group connect the same end in the height direction of the heat exchange component 1 to the second wall of the third sub-component 141. Therefore, it is possible to achieve that the third sub-component 141 has gaps on both sides in the height direction of the heat exchange component 1, so that the capacity of the liquid refrigerant can be adjusted locally at the preset position at the bottom of the heat exchange component 1, which is beneficial to adjust the heat exchange performance of different areas of the heat exchange component 1.
[0036] In some embodiments, as Figure 2 The heat exchange assembly 1 shown in FIG. 1 has a structure of the first piece 11, the second piece 12 and the third piece 13. Figure 1 The heat exchange assembly 1 shown in the embodiment has a similar structure, so it will not be repeated here. The focus is on the fourth element 14 which is different from the embodiment shown in FIG1. Figure 2The fourth component 14 shown in the embodiment includes a third sub-component 141, a fourth sub-component 142 and a fifth sub-component 144. The third sub-component 141 has a second cavity 140. It can be understood that the third sub-component 141 is like a frame. The third sub-component 141 has multiple inner walls and outer walls. In the height direction of the heat exchange component 1, the third sub-component 141 includes a first wall (not shown) and a second wall (not shown). The fourth sub-component 142 and the fifth sub-component 144 are in the second cavity 140. The fourth sub-component 142 is multiple. The fourth sub-component 142 includes a first end and a second end in the height direction of the heat exchange component 1. The width of the first end is greater than the width of the second end. The first wall and the second wall refer to the inner wall of the third sub-component. The fourth sub-component 142 One end is connected to the first wall, and the other end of the fourth sub-component 142 is the second end, and the second end is a free end. There is a gap between the free end and the second wall. Multiple fourth sub-components 142 are spaced apart in the length direction of the heat exchange component 1, and a third flow channel 143 is provided between two adjacent fourth sub-components 142. When the liquid refrigerant flows in from the first interface 111, a part of the refrigerant flows along the first flow channel 133 in the length direction of the heat exchange component 1, and another part of the refrigerant will flow into the third flow channel 143 through the first flow channel 133, so that the bottom of the heat exchange component 1 is covered with liquid refrigerant. The liquid refrigerant absorbs the heat generated by the electronic device and vaporizes, thereby taking away the heat generated by the electronic device and reducing the temperature of the electronic device.
[0037] In some embodiments, the third sub-component 141 is arranged away from the direction of the liquid refrigerant, and the width of the fourth sub-component 142 gradually decreases. This is because the liquid refrigerant at the bottom of the heat exchange component 1 gradually vaporizes as it absorbs heat from the electronic device. In some cases, even if the gas is not discharged in time, it will not cause the liquid refrigerant not to be replenished to the bottom of the heat exchange component due to the failure to discharge the gas in time, thereby affecting the heat exchange performance of the heat exchange component 1. Since the width of the fourth sub-component 142 is reduced, the third flow channel 143 between the two adjacent fourth sub-components 142 presents a wide top and narrow bottom structure from the top to the bottom, which is beneficial to improving the heat exchange performance of the heat exchange component 1.
[0038] In some embodiments, the fourth component 14 also includes a fifth sub-component 144, and the fifth sub-component 144 includes a third end and a fourth end in the height direction of the heat exchange component 1, and the width of the third end is greater than the width of the fourth end. The third end of the fifth sub-component 144 is connected to the second wall of the third sub-component 141, and the second end of the fifth sub-component 144 is a free end. The fifth sub-component 144 and the fourth sub-component 142 are staggered, so the two free ends of the fifth sub-component 144 and the fourth sub-component 142 will not contact, and will not block the passage of gaseous or gas-liquid two-phase refrigerant. On the one hand, the provision of the fifth sub-component 144 is beneficial to improving the connection reliability between the fourth component 14 and the third component 13 and the second component 12, and can also improve the pressure resistance of the heat exchange component 1.
[0039] In some embodiments, as Figure 3 In the heat exchange assembly 1 shown in FIG. 1 , the third component 13 and the fourth component 14 are located between the first component 11 and the second component 12. The first component 11 has a first interface 111 and a second interface 112. The fourth component 14 includes a third sub-component 141 and a plurality of fourth sub-components 142. The third sub-component 141 can be regarded as a frame. The third sub-component 141 has a first wall and a second wall opposite to each other in the height direction of the heat exchange assembly 1. The third component 13 has a second cavity 140. The plurality of fourth sub-components 142 are located in the second cavity 140. The fourth sub-components 142 The first end of the fourth sub-component 142 is connected to the first wall 1411 of the third sub-component 141, and the second end of the fourth sub-component 142 is connected to the second wall 1412 of the third sub-component 141. The surface of the fourth sub-component 142 is configured as a concave-convex structure, with multiple protrusions 1422 arranged in the extension direction of the fourth sub-component 142. A concave portion 1421 is provided between two adjacent protrusions 1422 in the extension direction of the fourth sub-component 1421. In the height direction (X direction) of the fourth component 14, the concave portions 1421 and the protrusions 1422 are alternately arranged. The third flow channel 143 between two adjacent fourth sub-components 142 has a generally wavy structure, which helps increase the heat exchange area within the fourth component 14 and improve the heat exchange performance of the heat exchange assembly 1.
[0040] In some embodiments, as Figure 4 In the heat exchange component 1 shown, the third component 13 and the fourth component 14 are between the first component 11 and the second component 12. The third component 13 includes a first sub-component 131 and a second sub-component 132. The third component 13 has a first cavity 130. The third component 13 can be regarded as a frame. The third component 13 has multiple inner walls, and the multiple inner walls include a third inner wall and a fourth inner wall in the length direction of the heat exchange component 1. There are multiple second sub-components 132. One end of the second sub-components 132 in the length direction is connected to the third wall of the third component 13, and the other end is not connected to other components. Another end of the second sub-components 132 in the length direction is connected to the fourth wall of the third component 13, and similarly, the other end is not connected to other components. Multiple second sub-components 132 are spaced apart in the height direction of the heat exchange component 1. The spaced arrangement means that a gap is provided between two adjacent second sub-components 132 in the length direction of adjacent heat exchange components 1. They are relatively arranged in the length direction of the heat exchange component 1, and a fourth flow channel 135 is provided between two adjacent second sub-components 132 in the length direction of the heat exchange component 1.
[0041] Furthermore, the fourth component 14 also includes multiple third sub-components 141 and multiple fourth sub-components 142. The multiple fourth sub-components 142 are spaced apart in the length direction of the heat exchange component 1. The first end of the fourth sub-component 142 is connected to the first wall of the third sub-component 141, and the second end of the fourth sub-component 142 is connected to the second wall. A third flow channel 143 is provided between two adjacent fourth sub-components 142 in the length direction of the heat exchange component 1. Part of the liquid refrigerant flowing in from the first interface 111 flows into the first flow channel 133, and another part flows into the third flow channel 143. Because the first flow channel 133 extends along the length direction of the heat exchange component 1, the entire bottom of the heat exchange component 1 can be covered with liquid refrigerant. The liquid refrigerant absorbs heat from the electronic components and vaporizes to take away the heat. The vaporized refrigerant is discharged through the second flow channel 134.
[0042] In some embodiments, as Figure 5 The heat exchange component 1 shown in FIG. 1 includes a first component 11, a second component 12, a third component 13, a fourth component 14 and a fifth component 15. The third component 13, the fourth component 14 and the fifth component 15 are located between the first component 11 and the fifth component 15. The third component 13 includes a first flow channel 133 and a second flow channel 134. The first flow channel 133 is located at the bottom of the heat exchange component 1 in the height direction, and the second flow channel 134 is located at the top of the heat exchange component 1 in the height direction. The fourth component 14 includes a third sub-component 141 and a fourth sub-component 142. The length direction of the fourth sub-component 142 forms an angle with the length direction of the fourth component 14. Multiple fourth sub-components 142 are arranged at intervals in the length direction of the heat exchange component 1. Two adjacent fourth sub-components have a third flow channel 143. Since the fourth component is inclined, the heat exchange area of the heat exchange component 1 can be increased by the inclined setting. On the other hand, the flow path of the refrigerant can also be increased, which is beneficial to improving the heat exchange performance of the heat exchange component 1.
[0043] Furthermore, in order to improve the heat exchange performance of the heat exchange component 1, a fifth component 15 is provided for further turbulent flow of the refrigerant. The fifth component 15 has a sixth flow channel, and the extension direction of the sixth flow channel and the extension direction of the third flow channel 143 are arranged in a cross-flow manner, thereby enhancing the turbulent flow of the refrigerant, which is beneficial to improving the heat exchange performance of the heat exchange component 1.
[0044] In some embodiments, as Figure 6 The heat exchange assembly 1 shown includes a first piece 11, a second piece 12, and a third piece 13.
[0045] The fourth component 14 and the fifth component 15, the third component 13, the fourth component 14 and the fifth component 15 are located between the first component 11 and the second component 12, the third component 13 has a first flow channel 133 and a second flow channel 134, the first component 11 has a first interface 111 and a second interface 112, the first interface 111 and the first flow channel 133 are connected, the fourth component 14 includes a third sub-component 141 and a plurality of fourth sub-components 142, the third sub-component 141 has a second cavity 140, the fourth sub-component 142 is located in the second cavity 140, and the plurality of fourth sub-components 142 are spaced apart in the length direction of the heat exchange component 1. 2 is arranged at an angle to the height direction of the heat exchange component 1. It can be understood that the length direction of the fourth sub-component 142 can also be parallel to the height direction of the heat exchange component 1. The liquid refrigerant flows in from the first interface 111, part of the liquid refrigerant flows into the first flow channel 133, and part of the refrigerant flows into the third flow channel 143. There is a cross flow of refrigerant between the third flow channel 143 and the first flow channel 133. The first flow channel 133 extends in the length direction of the heat exchange component 1. Therefore, the liquid refrigerant can cover the bottom of the heat exchange component 1, and the liquid refrigerant absorbs the heat emitted by the electronic device and vaporizes.
[0046] Furthermore, in order to enhance the turbulent flow effect of the refrigerant in the heat exchange component 1, a fifth component 15 is provided. The fifth component 15 has a plurality of through holes 151, and the through holes 151 are connected to the third flow channel 143, thereby enhancing the turbulent flow effect of the refrigerant and thus improving the heat exchange performance of the heat exchange component.
[0047] In some embodiments, since the first interface 111 and the second interface 121 can be provided on different panels, it is necessary to make corresponding design changes to the middle piece located between the first piece 11 and the second piece 12. Specifically, Figures 7 to 9As shown, the first interface 111 is provided on the first component 11, the second interface 121 is provided on the second component 12, the third component 13 includes a first sub-component 131 and a second sub-component 132, the first sub-component 131 has a first cavity 130, and the second sub-component 132 is connected to the inner wall 1311 of the first sub-component at both ends in the length direction, and one end of the second sub-component 132 in the width direction is not connected to the inner wall of the first sub-component 131, thereby forming a first flow channel 133, the first flow channel 133 is close to one side in the height direction of the heat exchange component, and the first flow channel 133 extends in the length direction of the heat exchange component, the fourth component 14 includes a third sub-component 141 and a plurality of fourth components 14, the third sub-component 141 has a second cavity 140, and the plurality of fourth sub-components 142 are located in the second cavity 140, and one end of the fourth sub-component 142 is connected to the third The inner wall of the sub-component 141 is connected, and the other end of the third sub-component 141 is not connected to the inner wall of the fourth sub-component 142 to form a second flow channel 145. The second flow channel 145 extends in the length direction of the heat exchange component. The two adjacent third sub-components 141 have a third flow channel 143. The third flow channel 143 extends in the height direction of the heat exchange component. The first flow channel 133 and the second flow channel 145 are arranged on both sides of the height direction of the heat exchange component. That is to say, the first flow channel 133 is located at one end in the height direction, and the second flow channel 145 is located at the other end in the height direction. The first interface 111 is connected to the first flow channel 133, and the second interface 121 is connected to the second flow channel 145. One end of the third flow channel 143 is connected to the first flow channel 133, and the other end of the third flow channel 143 is connected to the second flow channel 145.
[0048] Furthermore, since the refrigerant liquid absorbs external heat and vaporizes inside the heat exchange component, when the first interface 111 is the liquid refrigerant inlet and the second interface 121 is the gas refrigerant outlet, the width of the third sub-component 141 in the extension direction of the third flow channel 143 gradually decreases, thereby facilitating the second flow channel 145 to have a larger internal volume as a gaseous area, which is beneficial to improving the reliability of the heat exchange component.
[0049] In some embodiments, as Figure 9 In order to improve the welding reliability of the heat exchange assembly shown, a fifth sub-component 144 is also provided in the second cavity 140. In the length direction of the heat exchange assembly, the fourth sub-component 142 and the fifth sub-component 144 are staggered in the length direction of the heat exchange assembly. On the one hand, it is beneficial to balance the thermal stress inside the heat exchange assembly, and on the other hand, it is beneficial to improve the pressure resistance performance of the heat exchange assembly.
[0050] In some embodiments, such as Figure 10In the heat exchange assembly shown, the fifth sub-component 144 and the fourth sub-component 142 can also be arranged relative to each other. It can be understood that the fourth sub-component 142 and the fifth sub-component 144 are fixedly connected together, or part of the fifth sub-component 144 is connected to the fourth sub-component 142, thereby increasing the welding area of the heat exchange assembly and improving the reliability of the heat exchange assembly. Further, the heat exchange assembly includes a first piece 11, a second piece 12, a third piece 13, a fourth piece 14 and a sixth piece. The first piece 11 and the second piece 12 serve as a base plate and a cover plate. The first piece 11 is provided with a first interface 111, and the second piece 12 is provided with a second interface 121. The third piece 13, the fourth piece 14 and the sixth piece 16 are located between the first piece 11 and the second piece 12, as shown in FIG. Figure 11 As shown, the third component 13 includes a first sub-component 131 and a second sub-component 132. The first sub-component 131 has a first cavity 130. The second sub-component 132 is located in the first cavity 130. Both ends of the second sub-component 132 in the length direction are connected to the inner wall of the first component 11, and one end of the second sub-component 132 in the width direction is not connected to the inner wall of the first sub-component 131 to form a first flow channel 133. The first flow channel 133 extends in the length direction of the heat exchange component, and the first interface 111 is connected to the first flow channel 133.
[0051] Further, such as Figure 12 As shown, the fourth component 14 also includes a third sub-component 141, a fourth sub-component 142 and a fifth sub-component 144, the third sub-component 141 includes a first cavity 130, a plurality of fourth sub-components 142 are located in the first cavity 130, one end of the fourth sub-component 142 is connected to the first wall 1411 of the third sub-component, a plurality of fourth sub-components 142 are spaced apart in the length direction of the heat exchange component, a plurality of fifth sub-components 144 are located in the first cavity 130, a plurality of fifth sub-components 144 are spaced apart in the length direction of the heat exchange component, one end of the fifth sub-component 144 is connected to the second wall 1412 of the third sub-component, the other end of the fifth sub-component 144 is connected to the other end of the fourth sub-component 142, the fourth component 14 includes a third flow channel 143, the third flow channel 143 is located between adjacent fourth sub-components 142, and the third flow channel 143 extends in the height direction of the heat exchange component.
[0052] The sixth component is provided with a second flow channel 161, which extends in the length direction of the heat exchange component. The fifth sub-component 144 and the second flow channel 161 are on the same side in the height direction of the heat exchange component, and the first flow channel 133 and the second flow channel 161 are on different sides in the height direction of the heat exchange component. Therefore, when the heat exchange component is in working state, the liquid refrigerant flowing in from the first interface 111 is distributed all over the bottom of the heat exchange component along the extension direction of the first flow channel 133. Furthermore, the liquid refrigerant is transported to each third flow channel 143 through the first flow channel 133. The refrigerant circulates along the extension direction of the third flow channel 143, and is vaporized into gaseous refrigerant by absorbing the heat generated by the electronic devices (not shown in the figure) on the heat exchange component. Then the gaseous refrigerant flows from the gap between the two adjacent fifth sub-components 144 to the second flow channel 161, and is finally discharged from the second interface 121.
[0053] On the other hand, the present application also provides a radiator 100 having a heat exchange component 1, such as Figure 13 In the radiator 100 shown in the embodiment of the present application, the heat exchange component 1 is used as an evaporator. The liquid refrigerant inside the heat exchange component 1 absorbs the electronic devices and evaporates into a gaseous state, while the condenser condenses the gaseous refrigerant into a liquid refrigerant, which is beneficial to the circulation of the refrigerant. Specifically, the condenser includes a first tube 21, a second tube 22 and a heat exchange tube 24. One end of the heat exchange tube 24 is connected to the first tube 21, and the other end of the heat exchange tube 24 is connected to the second tube 22. There are multiple heat exchange tubes 24, and the multiple heat exchange tubes 24 are spaced apart in the thickness direction of the heat exchange tube 24. The heat exchange tube 24 connects the first tube 21 and the second tube 22. In order to improve the heat exchange performance of the condensing component, the condensing component also includes fins 23. The corrugations can also be horizontally inserted fins 23. The heat exchange tubes 24 are fixed by inserting the notches of the fins 23. It can be understood that the fins 23 can also be microchannel corrugated fins 23. The heat exchange tubes 24 and the fins 23 are spaced apart, and the fins 23 are arranged between two adjacent heat exchange tubes 24.
[0054] It should be noted that, in order to clearly display the schematic diagram, the condenser assembly only illustrates a portion of the heat exchange tubes 24 and fins 23.
[0055] In order to connect the interior of the heat exchange component 1 and the condensing component, the radiator 100 also includes a first connecting pipe 31 and a second connecting pipe 32, the first connecting pipe 31 is connected to the first interface 111, the first pipe 21 has a third interface 211, and the second pipe 22 has a fourth interface 221. The radiator 100 also includes a first connecting pipe 31 and a second connecting pipe 32, the first connecting pipe 31 has a first channel 311, and the second connecting pipe 21 has a second channel 321. The first channel 311 connects the first interface 111 and the third interface 211, and the second channel 321 connects the second interface 112 and the fourth interface 221, and is used to input liquid refrigerant into the heat exchange component 1. The second connecting pipe 32 is connected to the second inlet, and is used to input gaseous refrigerant into the condensing component.
[0056] Generally, in order to improve the heat exchange performance of the radiator 100, in some embodiments, the heat exchange tube 24 of the condensing component is tilted relative to the horizontal plane, that is, the length direction of the heat exchange tube 24 and the height direction of the heat exchange component 1 are set at an angle of α, 60°≤α<90°. Within this angle range, it is beneficial to increase the potential energy of the liquid refrigerant, to increase the reflux speed of the liquid refrigerant, and to improve the heat exchange performance of the heat exchange component.
