[0082] The flow guiding structure 184 and the flow guiding channel 1841 . DETAILED DESCRIPTION

[0083] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0084] The present application discloses a heat sink 18 .

[0085] Reference below Figure 1-Figure 22 The heat sink 18 according to the embodiment of the present application will be described.

[0086] In some embodiments, as Figures 1-6 As shown, the radiator 18 includes an evaporator 181 , a condenser 182 and a busbar 183 .

[0087] The evaporator 181 and the condenser 182 are interconnected through the busbar 183, and the evaporator 181, the condenser 182 and the busbar 183 are used to circulate the phase change medium; wherein, the flow direction of the phase change medium in the evaporator 181 is a first direction, and the flow direction of the phase change medium in the condenser 182 is a second direction, and the first direction and the second direction both intersect with the length direction of the busbar 183, and the busbar 183 includes a first section 1831 and a second section 1832 connected along the length direction, the evaporator 181 is connected to the first section 1831, and the condenser 182 is connected to the second section 1832.

[0088] Specifically, if Figures 1-6 、 Figure 10 、 Figure 14 and Figure 18 As shown, the first direction can be vertical or oblique at an acute angle to the vertical; the second direction can be vertical or oblique at an acute angle to the vertical. The length direction of the collector 183 can include a single direction, which can be horizontal or oblique at an acute angle to the horizontal. The length direction of the collector 183 can also include multiple directions, where "multiple" means two or more. For example, the length direction of the collector 183 can include horizontal, longitudinal, vertical, oblique at an acute angle to the horizontal, oblique at an acute angle to the longitudinal, or oblique at an acute angle to the vertical.

[0089] For example, in some embodiments, Figure 1 As shown, the flow channel direction of the evaporator 181 and the flow channel direction of the condenser 182 are both inclined at an acute angle to the vertical direction, and the length direction of the confluence piece 183 is inclined at an acute angle to the horizontal direction.

[0090] For example, in other embodiments, Figure 3As shown, the flow channel direction of the evaporator 181 and the flow channel direction of the condenser 182 are both oblique directions that form an acute angle with the vertical direction, and the length direction of the confluence piece 183 includes an oblique direction that forms an acute angle with the vertical direction and an oblique direction that forms an acute angle with the horizontal direction.

[0091] For example, in some other embodiments, Figure 5 、 Figure 7 and Figure 8 As shown, the flow channel direction of the evaporator 181 and the flow channel direction of the condenser 182 are both oblique at an acute angle to the vertical direction, and the length direction of the conduit 183 includes an oblique direction at an acute angle to the longitudinal direction and an oblique direction at an acute angle to the transverse direction.

[0092] For example, in some other embodiments, Figure 2 As shown, the flow channel directions of the evaporator 181 and the condenser 182 are both vertical, and the length direction of the confluence piece 183 is horizontal.

[0093] The vertical direction may be the direction of gravity, and the transverse and longitudinal directions may be horizontal directions, that is, the transverse and longitudinal directions are two directions that intersect vertically on a horizontal plane.

[0094] In actual implementation, Figures 1-6 As shown, the evaporator 181 of the radiator 18 absorbs the heat generated by the electrical components 12 in the electrical device 10 during operation through the phase change medium inside. The phase change medium vaporizes after absorbing heat. The vaporized phase change medium rises along the flow path in the evaporator 181 to the conduit 183, and then flows into the condenser 182 of the radiator 18. Under the cooling of the external environment, the gaseous phase change medium releases heat and becomes a liquid phase change medium. Then, under the influence of gravity, the liquid phase change medium returns to the conduit 183 along the flow path in the condenser 182, and finally falls back into the evaporator 181, completing a heat dissipation cycle. Repeat the above process to dissipate the heat of the electrical components 12 in the electrical device 10 to the external environment, thereby reducing the temperature of the chamber where the electrical components 12 are located.

[0095] In the related art, traditional electrical equipment uses an air-to-air heat exchanger as a heat dissipation device to cool the internal electrical components. However, the air-to-air heat exchanger as a whole needs to be placed in the cavity where the electrical components are located, and the internal air duct of the air-to-air heat exchanger needs to be connected to the external environment. As the power level of the electrical equipment increases, the volume of the air-to-air heat exchanger also needs to increase. In order to match the demand for a large-volume air-to-air heat exchanger, the chassis of the electrical equipment greatly increases the space occupied by the electrical equipment, which is not conducive to the overall spatial layout of the electrical equipment.

[0096] It can be understood that there needs to be a vertical position difference between the evaporator 181 and the condenser 182 when they are arranged, so that the liquid phase change medium can fall back with the help of gravity. On the one hand, since the evaporator 181 is connected to the first section 1831 and the condenser 182 is connected to the second section 1832, the evaporator 181 and the first section 1831 can be accommodated in the chamber where the electrical component 12 is located, and the condenser 182 and the second section 1832 can be arranged outside the chamber where the electrical component 12 is located, which helps to reduce the internal space occupied by the radiator 18 and helps to optimize the spatial layout of the electrical components 12 inside the electrical equipment 10, thereby improving the space utilization rate of the electrical equipment 10; on the other hand, in terms of spatial layout, there are fewer changes to the structural form of the existing electrical equipment 10. Specifically, the gas-gas in the original position can be directly moved. The heat exchanger replaces the radiator 18 of this application without the need to introduce other components or make major modifications to the structure of the electrical equipment 10. It has high adaptability and is conducive to promotion and use. On the other hand, since the radiator 18 of this application adopts a phase change heat exchanger, the heat exchange performance is greatly improved compared to the air-to-air heat exchanger, thereby significantly optimizing the heat dissipation and cooling effect. The radiator 18 has no reserved interface with the outside, which greatly reduces the risk of leakage. Even if leakage occurs, the phase change working fluid will evaporate rapidly and will not cause major damage to the electrical components 12, thereby increasing the practicality of the radiator 18 and reducing the maintenance cost of the electrical equipment 10. On the other hand, based on the shared junction 183 between the evaporator 181 and the condenser 182, compared with the common air pipe and liquid pipe solutions, it not only simplifies the assembly process but also achieves cost control.

[0097] The radiator 18 provided in the embodiment of the present application greatly improves the heat exchange performance per unit space within a certain volume through the structural design in which the evaporator 181 is connected to the first section 1831 and the condenser 182 is connected to the second section 1832, significantly optimizes the heat dissipation effect, reduces the risk of leakage, is beneficial to the long-term safe and stable operation of the electrical equipment 10, reduces the maintenance cost of the electrical equipment 10, and at the same time reduces the internal space occupied by the radiator 18, which helps to optimize the spatial layout of the electrical components 12 inside the electrical equipment 10, thereby improving space utilization, and does not require the introduction of other components or major modifications to the existing structure, which is beneficial to promotion and use. In addition, the design of the evaporator 181 and the condenser 182 sharing the manifold 183 simplifies the assembly process and achieves cost control of the radiator 18.

[0098] In some embodiments, as Figures 1-8 As shown, the flow path of the evaporator 181 extends in a straight line.

[0099] In the related art, some electrical equipment also uses phase change heat sinks as radiators to cool internal electrical components. However, traditional phase change heat sinks have great limitations in layout due to the need to rely on gravity. Specifically, in order to maximize the heat dissipation capacity, the phase change heat sink can usually only be arranged in the top area of ​​the electronic equipment, resulting in the height space occupied by the electronic equipment being too large. In order to be arranged in the side area of ​​the electronic equipment, some phase change heat sinks bend or fold the shape of the evaporator to achieve the purpose of isolating the condenser outside the cavity where the electrical components are located. Although this solution can increase the diversity of the layout of the phase change heat sink, in actual applications, the medium flow resistance of the evaporator is greatly increased, resulting in a slower circulation rate of the phase change medium and reduced heat dissipation efficiency.

[0100] It can be understood that, based on the above-mentioned evaporator 181 being connected to the first section 1831 and the condenser 182 being connected to the second section 1832, in other words, the evaporator 181 and the condenser 182 are staggered along the length direction of the manifold 183. In this way, when the radiator 18 needs to be set on the side of the electrical equipment 10, the evaporator 181 does not need to be deformed or twisted in any shape or structure, and the common structure of the evaporator 181 can be retained, that is, the flow channel of the evaporator 181 extends in a straight line. In this case, the phase change medium can flow in a straight line in the flow channel of the evaporator 181, effectively reducing the medium flow resistance of the evaporator 181, accelerating the circulation rate of the phase change medium, and helping to reduce heat accumulation inside the electrical equipment 10, thereby significantly improving the heat dissipation efficiency.

[0101] In some embodiments, as Figures 1-8 As shown, the flow path of the condenser 182 extends along a straight line.

[0102] In the related art, some electrical equipment also uses phase change heat sinks as radiators to cool internal electrical components. However, traditional phase change heat sinks have great limitations in layout due to the need to rely on gravity. Specifically, in order to maximize the heat dissipation capacity, the phase change heat sink can usually only be arranged in the top area of ​​the electronic equipment, resulting in the height space occupied by the electronic equipment being too large. In order to be arranged in the side area of ​​the electronic equipment, some phase change heat sinks bend or fold the shape of the condenser to achieve the purpose of isolating the condenser outside the cavity where the electrical components are located. Although this solution can increase the diversity of the layout of the phase change heat sink, in actual applications, the medium flow resistance of the condenser is greatly increased, resulting in a slower circulation rate of the phase change medium and reduced heat dissipation efficiency.

[0103] It can be understood that, based on the above-mentioned evaporator 181 being connected to the first section 1831 and the condenser 182 being connected to the second section 1832, in other words, the evaporator 181 and the condenser 182 are staggered along the length direction of the manifold 183. In this way, when the radiator 18 needs to be set on the side of the electrical equipment 10, the condenser 182 does not need to be deformed or twisted in any shape or structure, and the common structure of the condenser 182 can be retained, that is, the flow channel of the condenser 182 extends in a straight line. In this case, the phase change medium can flow in a straight line in the flow channel of the condenser 182, effectively reducing the medium flow resistance of the condenser 182, accelerating the circulation rate of the phase change medium, and helping to reduce heat accumulation inside the electrical equipment 10, thereby significantly improving the heat dissipation efficiency.

[0104] In some embodiments, as Figures 1-8 As shown, the evaporator 181 is connected to the side 18312 of the first section 1831 , and the condenser 182 is connected to the side 18322 of the second section 1832 .

[0105] By connecting the evaporator 181 and the condenser 182 to the side of the busbar 183, the communication area between the evaporator 181 and the condenser 182 and the busbar 183 is increased, while the assembly difficulty between the evaporator 181 and the condenser 182 and the busbar 183 is reduced.

[0106] In some embodiments, as Figure 1 and Figure 2 As shown, the first section 1831 and the second section 1832 both extend along a third direction, an end 18311 of the first section 1831 and an end 18321 of the second section 1832 are butt-jointed, and the third direction intersects with the first direction.

[0107] In this embodiment, if Figure 1 and Figure 2 As shown, the first section 1831 and the second section 1832 can be integrally formed, and the first section 1831 and the second section 1832 are both straight sections. The first end of the first section 1831 along the third direction is directly connected to the second end of the second section 1832 along the third direction to form a continuous pipeline. The entire conduit 183 is in a straight line shape. In this case, the length direction of the conduit 183 is the third direction.

[0108] In addition to being straight segments, the first segment 1831 and the second segment 1832 can also be designed into other shapes, such as arc segments, wave segments, or sawtooth segments, etc., which are not limited here.

[0109] For example, Figure 1 As shown, the first direction and the second direction intersect, the first direction is an oblique direction forming an acute angle with the vertical direction, the second direction is an oblique direction forming an acute angle with the vertical direction, and the third direction is an oblique direction forming an acute angle with the horizontal direction.

[0110] For example, Figure 2 As shown, the first direction and the second direction are parallel, the first direction and the second direction are both vertical, and the third direction is horizontal.

[0111] The heat sink 18 provided in the embodiment of the present application has a structural design in which the first section 1831 and the second section 1832 extend along the third direction and the ends are butt-connected, so that the busbar 183 extends along the third direction as a whole, which is conducive to arrangement in a limited space and improves space utilization. At the same time, the overall structure is simple, which reduces the flow resistance of the phase change medium in the busbar 183 and facilitates rapid heat exchange.

[0112] In some embodiments, as Figure 3 and Figure 4 As shown, the first section 1831 extends along the fourth direction, the second section 1832 extends along the fifth direction intersecting the fourth direction, the end 18311 of the first section 1831 and the end 18321 of the second section 1832 are bent and connected, and the fourth direction intersects with the first direction.

[0113] In this embodiment, if Figure 3 and Figure 4 As shown, the first section 1831 and the second section 1832 can be integrally formed, and the first section 1831 and the second section 1832 are both straight sections. One end of the first section 1831 along the fourth direction is connected to one end of the second section 1832 along the fifth direction at a 90° bend to form a continuous pipe, and the entire conduit 183 is L-shaped. In this case, the length direction of the conduit 183 includes the fourth direction and the fifth direction.

[0114] The bending angle between the first section 1831 and the second section 1832 may be other angles besides the aforementioned 90°, such as 60°, 85° or 120°, etc., which is not limited here.

[0115] For example, Figure 3 As shown, the first direction, the second direction and the fifth direction are parallel to each other, the first direction, the second direction and the fifth direction are all oblique directions that form an acute angle with the vertical direction, and the fourth direction is oblique directions that form an acute angle with the horizontal direction.

[0116] For example, Figure 4 As shown, the first direction, the second direction and the fifth direction are parallel to each other, the first direction, the second direction and the fifth direction are vertical, and the fourth direction is horizontal.

[0117] The heat sink 18 provided in this embodiment of the present application, with the first section 1831 and the second section 1832 extending in different directions and connected by a bent end, can more flexibly adapt to the spatial layout within the electrical device 10, especially in situations where the space is limited or irregular. Furthermore, the bent portion can disperse and absorb forces generated by thermal expansion or mechanical vibration, providing additional structural strength.

[0118] In some embodiments, as Figure 3 and Figure 4 As shown, the condenser 182 is connected to the surface of the second section 1832 on the side facing away from the first section 1831 .

[0119] In actual implementation, Figure 3 and Figure 4 As shown, when the radiator 18 is installed, at least a portion of the condenser 182 is higher than the evaporator 181 in the direction of gravity to maintain the smooth flow of the phase change medium. Specifically, after the radiator 18 is placed, the condenser 182 as a whole can be completely located above the evaporator 181 in the direction of gravity to minimize the flow resistance of the phase change medium. The condenser 182 can be installed on the side 18322 of the second section 1832 and located on the side of the second section 1832 along the fourth direction and away from the first section 1831 and the evaporator 181. In this case, the first section 1831 and the evaporator 181 have less interference with the condenser 182, and the air duct of the condenser 182 will not be largely blocked by the first section 1831 and the evaporator 181, thereby improving the heat exchange efficiency of the condenser 182.

[0120] The radiator 18 provided in the embodiment of the present application reduces the interference of the first section 1831 and the evaporator 181 on the condenser 182 through the layout design in which the condenser 182 is connected to the surface of the second section 1832 facing away from the first section 1831, thereby improving the heat exchange efficiency of the condenser 182.

[0121] In some embodiments, as Figure 3 and Figure 4 As shown, the conduit 183 has multiple plate surfaces, the evaporator 181 includes multiple first heat exchange plates 1811, and the condenser 182 includes multiple second heat exchange plates 1821. One end of the first heat exchange plate 1811 is connected to the plate surface on one side of the conduit 183, and one end of the second heat exchange plate 1821 is connected to the plate surface on one side of the conduit 183.

[0122] The first heat exchange plate 1811 is arranged in a direction parallel to the first direction, and the second heat exchange plate 1821 is arranged in a direction parallel to the second direction.

[0123] It is understandable that if Figure 3 and Figure 4As shown, the cross section of the flow converging piece 183 is flat, i.e. the height of the flow converging piece 183 is much smaller than the width and length of the flow converging piece 183, so that the flow converging piece 183 appears to be a flat tube in appearance, and the plate surface is the large surface of the flat tube-shaped flow converging piece 183. The first heat exchange plate 1811 and the second heat exchange plate 1821 can be connected to the plate surface on the same side of the flow converging piece 183 or on different sides of the flow converging piece 183. By connecting the plate surface to the first heat exchange plate 1811 and the second heat exchange plate 1821, the contact area between the flow converging piece 183 and the evaporator 181 and the condenser 182 is increased, so as to further improve the heat exchange efficiency and optimize the heat exchange effect.

[0124] In some embodiments, as shown in Figure 5-Figure 8 , the first section 1831 extends along a sixth direction, and the second section 1832 extends along a seventh direction intersecting the sixth direction. The end 18311 of the first section 1831 and the side 18322 or end 18321 of the second section 1832 are connected.

[0125] In this embodiment, as shown in Figure 5 and Figure 6 , the first section 1831 and the second section 1832 can be integrally formed. The first section 1831 and the second section 1832 are both straight sections. One end of the first section 1831 along the sixth direction is connected to the middle region of the side 18322 of the second section 1832 at an angle of 90°, forming a continuous pipeline. The entire flow converging piece 183 is T-shaped. In this case, the length direction of the flow converging piece 183 includes the sixth direction and the seventh direction.

[0126] In other embodiments, as shown in Figure 7 and Figure 8 , the first section 1831 and the second section 1832 can be integrally formed. The first section 1831 and the second section 1832 are both straight sections. One end of the first section 1831 along the sixth direction is connected to one end of the second section 1832 along the seventh direction at an angle of 90°, forming a continuous pipeline. The entire flow converging piece 183 is L-shaped. In this case, the length direction of the flow converging piece 183 includes the sixth direction and the seventh direction.

[0127] The bending angle between the first section 1831 and the second section 1832 can be other angles besides the above-mentioned 90°, such as 75°, 88.6°, 100°, or 150°, etc., which is not limited here.

[0128] Exemplarily, as shown in Figure 5 , Figure 7 and Figure 8As shown, the first direction and the second direction are parallel, and both the first direction and the second direction are oblique at an acute angle to the vertical direction. The sixth direction is oblique at an acute angle to the horizontal direction, and the seventh direction is oblique at an acute angle to the longitudinal direction.

[0129] For example, Figure 6 As shown, the first direction is parallel to the second direction, the first direction and the second direction are both vertical, the sixth direction is horizontal, and the seventh direction is longitudinal.

[0130] The radiator 18 provided in the embodiment of the present application can more effectively utilize space and reduce the volume occupied by the radiator 18 through the structural design in which the first section 1831 and the second section 1832 extend in different directions and the end 18311 of the first section 1831 is connected to the side 18322 or the end 18321 of the second section 1832. At the same time, it provides more structural flexibility, allowing the busbar 183 to be arranged in different directions to adapt to the specific spatial layout and structural requirements inside the electrical equipment 10.

[0131] It should be noted that, in addition to the four aforementioned embodiments, the current busbar 183 of the present application can also be designed in various other configurations, such as a cross-connection of the first section 1831 and the second section 1832, etc., without limitation herein. In actual design, a suitable configuration can be selected based on the space conditions and heat dissipation requirements of the electrical device 10.

[0132] In some embodiments, as Figure 2 、 Figure 4 and Figure 9 As shown, the radiator 18 further includes a flow guiding structure 184 .

[0133] The flow guiding structure 184 is disposed in the flow confluence piece 183 , and the flow guiding structure 184 forms a flow guiding channel 1841 for promoting the phase change medium to flow toward the end portion of the flow confluence piece 183 .

[0134] The flow guiding structure 184 may include but is not limited to a guide plate, a fin, a guide tube or other forms of diversion devices, which are not limited here.

[0135] For example, in some embodiments, Figure 2 、 Figure 4 and Figure 9 As shown, the flow guiding structure 184 includes a flow guide plate.

[0136] In some embodiments, as Figure 2As shown, the flow guide passage 1841 formed by the flow guide structure 184 is obliquely shaped, specifically, one end of the flow guide passage 1841 can be directed to the distal end of the evaporator 181 along the third direction, and the other end of the flow guide passage 1841 can be directed to the distal end of the condenser 182 along the third direction. Such a design enables the phase change medium to be more guided to the distal ends of the evaporator 181 and the condenser 182, reducing the local dense accumulation of the phase change medium.

[0137] In some embodiments, as shown in Figure 4 , and Figure 9 , the flow guide structure 184 forms a plurality of flow guide passages 1841, and the design principle of the flow area of the plurality of flow guide passages 1841 can be “far large and near small”, specifically, the flow area of the flow guide passage 1841 close to the distal end of the evaporator 181 can be larger than the flow area of the flow guide passage 1841 close to the middle of the evaporator 181, and the flow area of the flow guide passage 1841 close to the middle of the evaporator 181 can be larger than the flow area of the flow guide passage 1841 close to the proximal end of the evaporator 181. Such a design helps to make the flow distribution of the phase change medium in the evaporator 181 and the condenser 182 more uniform, reducing local temperature fluctuations.

[0138] The heat sink 18 provided by the embodiments of the present application realizes the orderly flow of the phase change medium in the flow collector 183 through the design of the flow guide structure 184, so that the phase change medium can enter the evaporator 181 and the condenser 182 uniformly and efficiently, which helps to improve the overall heat dissipation efficiency of the heat sink 18. At the same time, the flow guide structure 184 can realize the flow distribution of the phase change medium at the distal end and the proximal end by adjusting the distribution and flow area of the flow guide passage 1841, thereby reducing local temperature fluctuations and maintaining the stable operation of the electrical equipment 10.

[0139] In some embodiments, as shown in Figure 1 , Figure 2 , and Figure 5-Figure 8 , the flow collector 183 is a circular tube type.

[0140] In this embodiment, as shown in Figure 1 , Figure 2 , and Figure 5-Figure 8 , the first section 1831 and the second section 1832 are both cylindrical tubes, and the ports along the length direction of the first section 1831 are all circular, and the ports along the length direction of the second section 1832 are all circular.

[0141] In some other embodiments, the flow collector 183 is an elliptical tube type, that is, the first section 1831 and the second section 1832 are both elliptical cylindrical tubes, and the ports along the length direction of the first section 1831 are all elliptical, and the ports along the length direction of the second section 1832 are all elliptical.

[0142] The radiator 18 provided in the embodiment of the present application designs the conduit 183 as a circular tube structure. The conduit 183 provides a smooth inner wall, which helps to reduce the friction resistance of the phase change medium during flow, and helps the phase change medium to flow more smoothly between the evaporator 181 and the condenser 182, thereby improving the flow efficiency of the phase change medium. At the same time, the manufacturing process of the circular tube conduit 183 is relatively mature, and it can be produced through various forming techniques (such as stretching, bending, etc.), which helps to reduce manufacturing costs and improve production efficiency. In addition, the circular tube structure exhibits good stability when subjected to internal pressure, which helps to improve the reliability and durability of the entire radiator 18.

[0143] In some embodiments, as Figure 3 and Figure 4 As shown, the manifold 183 is a flat tube type.

[0144] In this embodiment, if Figure 3 and Figure 4 As shown, the first section 1831 and the second section 1832 are both long flat tubes, and the ports of the first section 1831 along the length direction are both rectangular, and the ports of the second section 1832 along the length direction are both rectangular.

[0145] The radiator 18 provided in the embodiment of the present application can provide a larger surface area to volume ratio by designing the manifold 183 as a flat tube structure, increase the contact area between the phase change medium and the tube wall, and thus help improve the heat exchange efficiency. At the same time, the flat tube manifold 183 can more easily adapt to the layout requirements inside the electrical equipment 10, especially when space is limited or a specific direction is required.

[0146] In some embodiments, as Figures 1-6 - Figure 8 As shown, the evaporator 181 includes a first heat exchange plate 1811 and a first heat dissipation fin 1812 .

[0147] The first heat exchange plate 1811 is used for circulating the phase change medium; the first heat dissipation fins 1812 are installed on the first heat exchange plate 1811.

[0148] In this embodiment, the first heat exchange plate 1811 can adopt a microchannel design, that is, a large number of tiny flow channels are processed inside the first heat exchange plate 1811 for circulating the phase change medium, and the first heat dissipating fins 1812 are tightly attached to the surface of these microchannels.

[0149] The connection method between the first heat exchange plate 1811 and the first heat dissipating fin 1812 may include but is not limited to welding, riveting or pressing, etc., which is not limited here.

[0150] For example, in some embodiments, the first heat exchange plate 1811 and the first heat dissipating fins 1812 are connected by welding.

[0151] The first heat dissipating fins 1812 can be designed to be straight, zigzag, needle-shaped, or wavy, etc., which is not limited here.

[0152] For example, in some embodiments, Figures 1-6 - Figure 8 As shown, the first heat dissipating fins 1812 are designed to be sawtooth-shaped.

[0153] The radiator 18 provided in the embodiment of the present application increases the surface area of ​​the evaporator 181 through the arrangement of the above-mentioned first heat exchange plate 1811 and the first heat dissipation fins 1812, which helps to increase the contact area between the evaporator 181 and the surrounding air, promotes the transfer of heat within the evaporator 181, and thus improves the heat exchange efficiency of the evaporator 181.

[0154] In some embodiments, as Figures 1-6 - Figure 8 As shown, the condenser 182 includes: a second heat exchange plate 1821 and a second heat dissipation fin 1822 .

[0155] The second heat exchange plate 1821 is used for circulating the phase change medium; the second heat dissipation fins 1822 are installed on the second heat exchange plate 1821.

[0156] In this embodiment, the second heat exchange plate 1821 can adopt a microchannel design, that is, a large number of tiny flow channels are processed inside the second heat exchange plate 1821 for circulating the phase change medium, and the second heat dissipating fins 1822 are closely attached to the surface of these microchannels.

[0157] The connection method between the second heat exchange plate 1821 and the second heat dissipating fin 1822 may include but is not limited to welding, riveting or crimping, etc., which is not limited here.

[0158] For example, in some embodiments, the second heat exchange plate 1821 and the second heat dissipating fins 1822 are connected by crimping.

[0159] The second heat dissipation fins 1822 can be designed to be straight, zigzag, needle-shaped, or wavy, etc., which is not limited here.

[0160] For example, in some embodiments, Figures 1-6 - Figure 8 As shown, the second heat dissipation fins 1822 are designed to be sawtooth-shaped.

[0161] In other embodiments, a heat pipe is embedded in the second heat exchange plate 1821 , one end of the heat pipe contacts the phase change medium, and the other end is connected to the second heat dissipation fin 1822 . The heat pipe utilizes the phase change process of the internal working medium to efficiently transfer heat.

[0162] The radiator 18 provided in the embodiment of the present application increases the surface area of ​​the condenser 182 through the arrangement of the above-mentioned second heat exchange plate 1821 and the second heat dissipation fins 1822, helps to increase the contact area between the condenser 182 and the surrounding air, promotes the transfer of heat within the condenser 182, and thus improves the heat exchange efficiency of the condenser 182.

[0163] In some embodiments, as Figure 1 、 Figure 2 and Figure 5-Figure 8 As shown, the end of the first heat exchange plate 1811 is connected to the side 18312 of the first section 1831, and the first heat dissipation fin 1812 is installed on the side of the first heat exchange plate 1811; the end of the second heat exchange plate 1821 is connected to the side 18322 of the second section 1832, and the second heat dissipation fin 1822 is installed on the side of the second heat exchange plate 1821.

[0164] Therein, a plurality of first heat dissipating fins 1812 may be provided, and the plurality of first heat dissipating fins 1812 are distributed at intervals, and a plurality means two or more.

[0165] For example, in some embodiments, twelve first heat dissipating fins 1812 may be provided.

[0166] For example, Figure 1 、 Figure 2 and Figure 5-Figure 8 As shown, a plurality of first heat dissipating fins 1812 are distributed at intervals in the horizontal direction or in an oblique direction forming an acute angle with the horizontal direction, and the first heat dissipating fins 1812 may extend in the vertical direction or in an oblique direction forming an acute angle with the vertical direction.

[0167] Therein, a plurality of second heat dissipating fins 1822 may be provided, and the plurality of second heat dissipating fins 1822 are spaced apart and distributed, and a plurality means two or more.

[0168] For example, in some embodiments, ten second heat dissipating fins 1822 may be provided.

[0169] For example, Figure 1 、 Figure 2 and Figure 5-Figure 8 As shown, a plurality of second heat dissipating fins 1822 are spaced apart and distributed in the horizontal direction, the vertical direction, the oblique direction at an acute angle to the horizontal direction, or the oblique direction at an acute angle to the vertical direction. The second heat dissipating fins 1822 can extend in the vertical direction or the oblique direction at an acute angle to the vertical direction.

[0170] like Figure 1 、 Figure 2 and Figure 5-Figure 8 As shown, the first heat exchange plate 1811 is designed as a hollow structure and is interconnected with the first section 1831. The first heat exchange plate 1811 can be connected to the first section 1831 by welding, riveting, crimping or threading. The second heat exchange plate 1821 is designed as a hollow structure and is interconnected with the second section 1832. The second heat exchange plate 1821 can be connected to the second section 1832 by welding, riveting, crimping or threading.

[0171] The radiator 18 provided in the embodiment of the present application can maximize the heat exchange area through the design of the assembly form between the above-mentioned first heat exchange plate 1811, the first section 1831 and the first heat dissipating fin 1812, and the assembly form between the second heat exchange plate 1821, the second section 1832 and the second heat dissipating fin 1822. More heat can be transferred from the phase change medium to the environment in the same time, thereby improving the heat exchange efficiency and making more effective use of space. Especially in occasions where space is limited, it can reduce the occupancy of the evaporator 181 in the length or width direction, leaving more space for other components, and avoiding obstacles or space limitations that may be encountered when installing at the top or bottom, making the overall layout more compact and reasonable.

[0172] In some embodiments, as Figure 1 、 Figure 2 and Figure 5-Figure 8 As shown, the evaporator 181 further includes a first manifold 1813 .

[0173] The first manifold 1813 is connected to one end of the first heat exchange plate 1811 away from the first section 1831 .

[0174] In this embodiment, if Figure 1 、 Figure 2 and Figure 5-Figure 8 As shown, the first manifold 1813 can be designed as a circular tube type, the first end of the first heat exchange plate 1811 along the first direction can be connected to the first section 1831, and the second end of the first heat exchange plate 1811 along the first direction can be connected to the side of the first manifold 1813. A large amount of liquid phase change medium can gradually leave the condenser 182 and flow to the manifold 183, and finally fall back and gather in the first manifold 1813.

[0175] The connection method between the first manifold 1813 and the first heat exchange plate 1811 may include but is not limited to welding, riveting or crimping, etc., which is not limited here.

[0176] For example, in some embodiments, the first manifold 1813 and the first heat exchange plate 1811 are connected by welding.

[0177] The radiator 18 provided in the embodiment of the present application, through the arrangement of the above-mentioned first manifold 1813, helps to evenly distribute the liquid phase change medium, so that the heat exchange efficiency of each part of the first heat exchange plate 1811 is kept as consistent as possible, and at the same time more effectively controls the flow of the phase change medium in the evaporator 181, reduces dead zones and eddies, and thus improves the heat exchange performance of the evaporator 181.

[0178] In some embodiments, as Figure 1 、 Figure 2 and Figure 5-Figure 8 As shown, the condenser 182 further includes a second manifold 1823 .

[0179] The second manifold 1823 is connected to one end of the second heat exchange plate 1821 away from the second section 1832 .

[0180] In this embodiment, if Figure 1 、 Figure 2 and Figure 5-Figure 8 As shown, the second manifold 1823 can be designed as a circular tube type, the first end of the second heat exchange plate 1821 along the second direction can be connected to the side of the second manifold 1823, and the second end of the first heat exchange plate 1811 along the second direction can be connected to the second section 1832. A large amount of gaseous phase change medium can gradually leave the evaporator 181 and flow to the manifold 183, and finally rise and converge into the second manifold 1823.

[0181] The connection method between the second manifold 1823 and the second heat exchange plate 1821 may include but is not limited to welding, riveting or crimping, etc., which is not limited here.

[0182] For example, in some embodiments, the second manifold 1823 and the second heat exchange plate 1821 are connected by welding.

[0183] The radiator 18 provided in the embodiment of the present application, through the arrangement of the above-mentioned second manifold 1823, helps to evenly distribute the gaseous phase change medium, so that the heat exchange efficiency of each part of the second heat exchange plate 1821 is kept as consistent as possible, and at the same time more effectively controls the flow of the phase change medium in the condenser 182, reduces dead zones and eddies, and thus improves the heat exchange performance of the condenser 182.

[0184] In some embodiments, as Figure 3 and Figure 4As shown, the first heat exchange plate 1811 includes a plurality of spaced-apart plates, the sides of the plurality of first heat exchange plates 1811 are connected to the sides 18312 of the first section 1831, and the first heat dissipating fins 1812 are installed between two adjacent first heat exchange plates 1811; the second heat exchange plate 1821 includes a plurality of spaced-apart plates, the sides of the plurality of second heat exchange plates 1821 are connected to the sides 18322 of the second section 1832, and the second heat dissipating fins 1822 are installed between two adjacent second heat exchange plates 1821.

[0185] Here, multiple means two or more.

[0186] For example, in some embodiments, eight first heat exchange plates 1811 may be provided, and correspondingly, seven first heat dissipating fins 1812 may be provided.

[0187] For example, Figure 3 and Figure 4 As shown, the plurality of first heat exchange plates 1811 are spaced apart and distributed in the horizontal direction or in an oblique direction forming an acute angle with the horizontal direction. The first heat exchange plates 1811 may extend in the vertical direction or in an oblique direction forming an acute angle with the vertical direction.

[0188] For example, in some embodiments, fifteen second heat exchange plates 1821 may be provided, and correspondingly, fourteen second heat dissipating fins 1822 may be provided.

[0189] For example, Figure 3 and Figure 4 As shown, the plurality of second heat exchange plates 1821 are spaced apart and distributed in the longitudinal direction or in an oblique direction forming an acute angle with the longitudinal direction. The second heat exchange plates 1821 may extend in the vertical direction or in an oblique direction forming an acute angle with the vertical direction.

[0190] In actual implementation, multiple first heat exchange plates 1811 can be spaced apart and distributed along the length of first section 1831, with the sides of multiple first heat exchange plates 1811 tightly connected to the sides 18312 of first section 1831 to form a stable support structure. Multiple first heat exchange plates 1811 can be arranged in parallel or in other layouts suitable for the flow of phase change medium. Multiple second heat exchange plates 1821 can be spaced apart and distributed along the length of second section 1832, with the sides of multiple second heat exchange plates 1821 tightly connected to the sides 18322 of second section 1832 to form a stable support structure. Multiple second heat exchange plates 1821 can be arranged in parallel or in other layouts suitable for the flow of phase change medium. A first heat dissipation fin 1812 is installed between each two adjacent first heat exchange plates 1811. The first heat dissipation fin 1812 can be perpendicular or inclined to the surface of the first heat exchange plate 1811 to increase the heat exchange area and promote air flow, thereby improving the heat exchange efficiency; a second heat dissipation fin 1822 is installed between each two adjacent second heat exchange plates 1821. The second heat dissipation fin 1822 can be perpendicular or inclined to the surface of the second heat exchange plate 1821 to increase the heat exchange area and promote air flow, thereby improving the heat exchange efficiency.

[0191] The radiator 18 provided in the embodiment of the present application can make the temperature distribution in the evaporator 181 and the condenser 182 more uniform by spacing out and distributing the first heat exchange plates 1811 and installing the first heat dissipation fins 1812, and spacing out and distributing the second heat exchange plates 1821 and installing the second heat dissipation fins 1822, thereby helping to reduce the occurrence of local overheating and overcooling and improving the stability and reliability of the radiator 18.

[0192] The present application also discloses an electrical device 10 .

[0193] In some embodiments, as Figure 10-Figure 22 As shown, the electrical device 10 includes: a chassis 11, electrical components 12 and a heat sink 18 as any one of the above-mentioned ones.

[0194] The chassis 11 defines a first accommodating cavity 111 ; the electrical component 12 is installed in the first accommodating cavity 111 ; the evaporator 181 of the radiator 18 is located in the first accommodating cavity 111 , and the condenser 182 of the radiator 18 is located outside the chassis 11 .

[0195] It should be noted that the electrical equipment 10 may include but is not limited to an inverter, a converter or a combiner box, etc., which is not limited here.

[0196] The electrical device 10 may further include a protective cover 13 , which is mounted on the chassis 11 and defines a second accommodating cavity 131 . The condenser 182 is located in the second accommodating cavity 131 .

[0197] like Figure 10 、 Figure 14 and Figure 18 As shown, the chassis 11 can be a hollow structure with one side open, and is subsequently fixedly connected to other components (such as a cover plate, etc.) to form a closed first accommodating cavity 111. The protective cover 13 can be a hollow structure with one side open, and the non-open side of the chassis 11 can be connected to the open side of the protective cover 13 to form a second accommodating cavity 131.

[0198] like Figure 11-13 、 Figure 15-17 、 Figures 19-22 As shown, the evaporator 181 and the first section 1831 are arranged in the first accommodating cavity 111. The evaporator 181 is used to dissipate heat for the electrical component 12 in the first accommodating cavity 111. The electrical component 12 includes a PCB board 121 (Printed Circuit Board) and an electronic device 122 electrically connected to the PCB board 121. The condenser 182 and the second section 1832 are arranged in the second accommodating cavity 131. The condenser 182 is used to exchange heat with the external environment.

[0199] The electrical device 10 provided in the embodiment of the present application reduces the internal space occupied by the radiator 18 through the arrangement of the above-mentioned radiator 18, which helps to optimize the spatial layout of the electrical components 12 in the first accommodating cavity 111, thereby improving space utilization. The evaporator 181 and the condenser 182 are arranged in separate cavities, which helps to more effectively exchange heat and manage heat, improve the heat dissipation efficiency of the condenser 182, reduce the thermal impact on the evaporator 181, and at the same time greatly improve the heat exchange performance, significantly optimize the heat dissipation effect, reduce the risk of leakage, and are beneficial to the long-term safe and stable operation of the electrical device 10, and reduce the maintenance cost of the electrical device 10. In addition, the design of the evaporator 181 and the condenser 182 sharing the manifold 183 simplifies the assembly process and realizes cost control of the radiator 18.

[0200] In some embodiments, as Figure 12 、 Figure 16 and Figure 20 As shown, the busbar 183 of the heat sink 18 passes through the chassis 11 along the length direction.

[0201] It can be understood that since the busbar 183 of the radiator 18 passes through the chassis 11 in the length direction, it is only necessary to process a through hole on the chassis 11 that matches the end face of the busbar 183. The chassis 11 does not need to have a large-area opening. While not seriously affecting the structural strength of the chassis 11 itself, it also reduces the area required for sealing after processing the through hole, reduces the difficulty of the sealing operation, and thus helps to optimize the protection performance of the chassis 11.

[0202] In other embodiments, the busbar 183 of the heat sink 18 passes through the chassis 11 along the width direction.

[0203] In some other embodiments, the busbar 183 of the heat sink 18 passes through the chassis 11 along the height direction.

[0204] In some embodiments, as Figure 10 、 Figure 14 and Figure 18 As shown, the protective cover 13 has a first air outlet 132 and a second air outlet 133 that are separately arranged. The first air outlet 132 and the second air outlet 133 are respectively located on two adjacent walls of the protective cover 13 .

[0205] In this embodiment, if Figure 10 、 Figure 14 and Figure 18 As shown, the first air outlet 132 can be located on the wall of the protective cover 13 along the horizontal direction and opposite to the opening, and the first air outlet 132 can be provided with a wire mesh structure to achieve filtering protection; the second air outlet 133 can be located on the vertical wall and the longitudinal wall of the protective cover 13. Specifically, the second air outlet 133 can be located on the top wall of the protective cover 13 and a longitudinal wall, and the second air outlet 133 can be provided with a wire mesh structure to achieve filtering protection.

[0206] It is understandable that in the related art, in electrical equipment using an air-to-air heat exchanger as a radiator, after the air is sucked in from the external environment, the flow path needs to make four 90° turns before the heat-exchanged air can be returned to the external environment, resulting in a relatively large flow resistance. Figure 9 、 Figure 13 and Figure 17 As shown, since the present application adopts the aforementioned radiator 18, the flow path only needs to make one turn to send the heat-exchanged air back to the environment, and the resistance of the entire air path is greatly reduced, thereby effectively improving the heat exchange efficiency.

[0207] The electrical device 10 provided in the embodiment of the present application, through the arrangement of the first air outlet 132 and the second air outlet 133 distributed adjacent to each other on the protective cover 13, greatly reduces the flow resistance of the entire circulating air path compared to the solution using an air-to-air heat exchanger, thereby effectively improving the heat exchange efficiency.

The second fan 15 can be installed in the second accommodating chamber 131, and the second fan 15 can be arranged at the first air outlet 132, and can be connected to the protective cover 13 by means of threaded connection, riveting, or clamping.

[0211] There may be one or more first fans 14 and one or more second fans 15, where "more" means two or more.

[0212] For example, in some embodiments, Figure 11 、 Figure 13 、 Figure 15 、 Figure 17 、 Figure 19 、 Figure 21 and Figure 22 As shown, one first fan 14 is provided and four second fans 15 are provided.

[0213] The electrical equipment 10 provided in the embodiment of the present application realizes forced air flow in the first accommodating chamber 111 and the second accommodating chamber 131 through the arrangement of the above-mentioned first fan 14 and the second fan 15, which can effectively improve the heat dissipation efficiency, and can more accurately and independently control the airflow distribution in the first accommodating chamber 111 and the second accommodating chamber 131. It can adjust the speed and wind direction of the first fan 14 and the second fan 15 accordingly according to the heat source distribution and heat dissipation requirements of the first accommodating chamber 111 and the second accommodating chamber 131 to achieve the best heat dissipation effect.

[0214] In some embodiments, as Figure 11 、 Figure 15 、 Figure 19 and Figure 22 As shown, the electrical device 10 further includes a magnetic device 16 and a heat dissipation component 17 .

[0215] The magnetic device 16 is installed in the second accommodating cavity 131; the heat dissipation component 17 is installed in the second accommodating cavity 131, and the heat dissipation component 17 is separated from the heat sink 18 and the magnetic device 16.

[0216] In this embodiment, as shown in Figure 11 、 Figure 15 and Figure 19 and Figure 22 , the magnetic device 16 includes a plurality of magnetic devices 16 distributed at intervals, and a part of the plurality of magnetic devices 16 can be arranged above the heat sink 18 component in the longitudinal direction, and another part of the plurality of magnetic devices 16 can be arranged below the heat sink 18 component in the longitudinal direction, and the condenser 182 can be located on one side of the magnetic device 16 and the heat dissipation component 17 in the longitudinal direction, and specifically, the heat dissipation component 17 can define a vertical air duct, so as to orderly guide the airflow in the second accommodating cavity 131 to the magnetic device 16, and further cool the magnetic device 16.

[0217] wherein the plurality indicates two or more, for example, in some embodiments, as shown in Figure 12 and Figure 16 , the magnetic device 16 includes five magnetic devices 16 distributed at intervals, and three of the five magnetic devices 16 can be arranged above the heat sink 18 component in the longitudinal direction, and two of the five magnetic devices 16 can be arranged below the heat sink 18 component in the longitudinal direction.

[0218] The electrical equipment 10 provided by the embodiment of the present application can promote the airflow in the second accommodating cavity 131 to flow orderly to the magnetic device 16 through the arrangement of the magnetic device 16 and the heat dissipation component 17, so as to realize the heat dissipation and cooling of the magnetic device 16 and the condenser 182 by the second fan 15, so that the magnetic device 16 can work at an appropriate temperature to maintain the normal operation of the magnetic device 16.
