Description

Technical Field

[0001] This application relates to the field of heat dissipation technology, and in particular to a heat sink and an energy storage converter. Background Technology

[0002] As the power density of electrical products increases and the number of heat sources increases, the internal layout design of radiators becomes more complex. This requires designing more complex heat dissipation circuits, which in turn requires multiple processing and connection of multiple heat dissipation pipes, resulting in difficult processing, long processing time, and high process costs. Utility Model Content

[0003] Therefore, it is necessary to provide a heat sink that simplifies manufacturing while still meeting the requirements for forming a complex heat dissipation circuit.

[0004] The radiator includes a flow channel structure, a flow splitting structure, a fluid inlet, and a fluid outlet. The flow channel structure has multiple spaced sub-flow channels along a first direction. The flow splitting structure includes two flow splitters, which are respectively assembled at both ends of the flow channel structure. Each flow splitter has a flow splitting cavity. The flow splitting structure also includes a separator, which is disposed in the flow splitting cavity to divide the flow splitting cavity into at least two sub-cavities. The sub-cavities are connected to the corresponding sub-flow channels. The separators in the two flow splitters are staggered along the first direction. The fluid inlet and the fluid outlet are disposed in the flow splitting structure and are connected to the flow splitting cavity. The fluid inlet, the sub-cavities, the sub-flow channels, and the fluid outlet are sequentially connected to form a reciprocating fluid loop.

[0005] Understandably, a flow divider, by incorporating a separator within the flow chamber, divides the chamber into at least two sub-cavities. The connection between these sub-cavities and sub-channels creates a reciprocating fluid loop, increasing the heat dissipation area and enhancing heat dissipation performance. Furthermore, this design simplifies radiator assembly; the flow divider can be directly installed by splicing it onto both sides of the flow channel structure. This streamlined operation eliminates the need for multiple connecting pipes to link multiple sub-channels, reducing assembly steps, simplifying assembly, saving time, and lowering production costs.

The first flow divider is located at the bottom end of the flow channel structure, and the second flow divider is located at the top end of the flow channel structure. The fluid inlet and the fluid outlet are arranged downwards.

[0008] In one embodiment, the first diverter further includes a drain chamber; the drain chamber is located below the corresponding diverter chamber and is spaced apart from the corresponding diverter chamber; the fluid inlet and the fluid outlet are respectively connected to the corresponding sub-cavity and the drain chamber; The radiator also includes a valve, which is installed on the first distributor; the valve has a first channel, a second channel and a third channel, the first channel and the second channel are respectively connected to the drain chamber, and the third channel is connected to the sub-cavity located in the middle of the two separators; the valve can switch open and close to switch the communication state between the drain chamber and the sub-cavity located in the middle of the two separators.

[0009] In one embodiment, the heat sink has two flow channel structures, which are spaced apart along the first direction.

[0010] In one embodiment, the first distributor is provided with a corresponding separator at the middle position of each of the flow channel structures along the first direction; In the second splitter, along the first direction, the separator is disposed between the two flow channel structures.

[0011] In one embodiment, each of the flow dividers is provided with a separator, and the fluid inlet and the fluid outlet are located on opposite sides of the radiator.

[0023] Please see Figures 1 to 5 This application provides a radiator 100, which includes a flow channel structure 10 and a flow splitting structure 20. The flow channel structure 10 has a plurality of spaced sub-flow channels 11 along a first direction, and the sub-flow channels 11 are independent of each other. The flow splitting structure 20 includes two flow splitters 21, which are respectively assembled at both ends of the flow channel structure 10. Each flow splitter 21 has a flow splitting cavity 2101. The flow splitting structure 20 also includes a separator 22, which is disposed in the flow splitting cavity 2101 and is used to divide the flow splitting cavity 2101 into at least two sub-cavities 21011. The sub-cavities 21011 are connected to the corresponding sub-flow channels 11. Furthermore, the separators 22 in the two flow splitters 21 are staggered along the first direction to form a staggered spatial arrangement at both ends of the flow channel structure 10, so that the sub-cavities 21011 of the two flow splitters 21 can be interconnected.

[0024] like Figures 1 to 3The radiator 100 also includes a fluid inlet 101 and a fluid outlet 102, which are located in the flow distribution structure 20 and communicate with the flow distribution chamber 2101. Coolant flows from the fluid inlet 101 into a sub-chamber 21011 of a flow distributor 21, then through the sub-chamber 21011 into a number of sub-channels 11, and then through a number of sub-channels 11 into a sub-chamber 21011 of another flow distributor 21. Then, it returns through another number of sub-channels 11 to the flow distributor 21 with the fluid inlet 101, and so on, until finally flowing out of the flow distribution chamber 2101 from the fluid outlet 102. In other words, the fluid inlet 101, sub-cavity 21011, sub-flow channel 11, and fluid outlet 102 are sequentially connected to form a reciprocating fluid loop. The fluid can exchange heat with external energy-consuming equipment in the sub-flow channel 11, and then return to the distribution cavity 2101 through the sub-flow channel 11. The reciprocating fluid loop can ensure sufficient heat dissipation paths and improve the heat dissipation effect of the radiator 100. For example, the coolant can be water, fluorinated liquid, etc., and no specific limitation is made here.

[0025] In the aforementioned radiator 100, by cooperating with the flow channel structure 10 and the flow splitting structure 20, flow splitters 21 and corresponding separators 22 are respectively installed on both sides of the flow channel structure 10, a reciprocating fluid loop can be formed. The assembly is simple, and there is no need to set up multiple connecting pipes to connect each sub-flow channel 11, reducing processing steps, such as reducing CNC machining, brazing and other steps, shortening processing time, and thus reducing production costs.

[0026] like Figures 1 to 3 As shown, in an optional embodiment, one of the two flow dividers 21, which has a fluid inlet 101, has two partitions 22 that divide the flow chamber 2101 of the flow divider 21 into three sub-cavities 21011. The other flow divider 21 has one partition 22 that divides the flow chamber 2101 of the other flow divider 21 into two sub-cavities 21011. The fluid inlet 101 and the fluid outlet 102 are located in the same flow divider 21. For ease of explanation, the one with the fluid inlet 101 and the fluid outlet 102 is defined as the first flow divider 211, and the other is the second flow divider 212.

[0027] Thus, three sub-cavities 21011 are formed in the first distributor 211, and two sub-cavities 21011 are formed in the second distributor 212. If a sub-cavity 21011 located on the side of the first distributor 211 is provided with a fluid inlet 101, and another sub-cavity 21011 located on the side is provided with a fluid outlet 102; the coolant enters the sub-cavity 21011 located on the side of the first distributor 211 from the fluid inlet 101, and enters the opposite sub-cavity 21011 in the second distributor 212 through the sub-flow channel 11, and then enters the sub-cavity 21011 located in the middle of the first distributor 211 through the sub-flow channel 11, and then enters the other sub-cavity 21011 in the second distributor 212 through the sub-flow channel 11 again, and finally returns to the other sub-cavity 21011 located on the side of the first distributor 211 through the sub-flow channel 11, and is discharged from the fluid outlet 102 of the sub-cavity 21011. This configuration creates a reciprocating fluid loop with a longer heat dissipation path, which facilitates sufficient heat exchange of the coolant. Furthermore, the fluid outlet 102 and fluid inlet 101 are located on the same side, making it easier to connect the fluid inlet 101 and fluid outlet 102 to external pipes.

[0028] In other embodiments, the middle sub-cavity 21011 of the first diverter 211 can be configured to communicate with the fluid inlet 101, and the two side sub-cavities 21011 can be configured to communicate with the fluid outlet 102. This forms a U-shaped fluid loop starting from the middle sub-cavity 21011 of the first diverter 211, passing through the corresponding sub-channel 11, the sub-cavity 21011 of the second diverter 212, another part of the sub-channel 11 corresponding to the sub-cavity 21011 of the second diverter 212, and finally ending at the side sub-cavity 21011 of the first diverter 211. Two such U-shaped fluid loops can be formed on both sides of the middle sub-cavity 21011 of the first diverter 211. Of course, the sub-cavity 21011 in the middle of the first diverter 211 can be configured to communicate with the fluid outlet 102, and the two sub-cavities 21011 on the sides can be configured to communicate with the fluid inlet 101, thus forming a U-shaped fluid loop. In addition, by increasing the number of baffles, multiple reciprocating fluid loops can be formed based on the U-shaped fluid loop, which is not specifically limited here.

[0029] For ease of explanation, this application will take as an example a sub-cavity 21011 located on the side of the first diverter 211 with a fluid inlet 101 and another sub-cavity 21011 located on the side with a fluid outlet 102.

[0030] like Figure 1 and Figure 2As shown, in an optional embodiment, the first distributor 211 is located at the bottom end of the flow channel structure 10, and the second distributor 212 is located at the top end of the flow channel structure 10; the fluid inlet 101 and the fluid outlet 102 are arranged downwards. This allows the coolant in the radiator 100 to be discharged from the fluid inlet 101 and the fluid outlet 102 after heat dissipation is completed, facilitating maintenance and repair of the radiator 100.

[0031] like Figure 1 and Figure 2 As shown, in an optional embodiment, the first distributor 211 is further provided with a drain chamber 2111; the drain chamber 2111 is located below the corresponding distributor chamber 2101 and is spaced apart from the corresponding distributor chamber 2101. The fluid inlet 101 and the fluid outlet 102 are respectively connected to the corresponding sub-cavity 21011 and the drain chamber 2111. In the first distributor 211, the sub-cavity 21011 located on the side can directly discharge coolant through the fluid inlet 101 or the fluid outlet 102.

[0032] like Figures 1 to 5 As shown, the radiator 100 also includes a valve 40, which is installed on the first distributor 211. The valve 40 has a first channel, a second channel, and a third channel. The first and second channels are respectively connected to the drain chamber 2111, and the third channel is connected to the sub-cavity 21011 located in the middle of the two separators 22. The valve 40 can switch between opening and closing to switch the communication state between the drain chamber 2111 and the sub-cavity 21011 located in the middle of the two separators 22. When the valve 40 is closed, the drain chamber 2111 is disconnected from the sub-cavity 21011 located in the middle of the two separators 22, and a reciprocating fluid loop is formed in the radiator 100 for heat dissipation. When valve 40 is opened, the coolant in the sub-cavity 21011 located in the middle of the two separators 22 can enter valve 40 through the third channel and be divided into two parts. One part enters the drain chamber 2111 through the first channel, and the other part enters the drain chamber 2111 through the second channel. The coolant in the drain chamber 2111 can be discharged from the fluid inlet 101 and the fluid outlet 102 respectively. With this configuration, the coolant in the sub-cavity 21011 located in the middle of the first distributor 211 and the corresponding sub-channel 11 can enter the drain chamber 2111 through the opening of valve 40, and after being divided by the drain chamber 2111, it flows out from the fluid inlet 101 and the fluid outlet 102. This allows the coolant in the radiator 100 to be fully discharged after heat dissipation, reducing residue and facilitating subsequent inspection and maintenance of the radiator 100.

[0033] like Figures 1 to 5As shown, in a specific embodiment, the radiator 100 is provided with two flow channel structures 10. Along the first direction, the two flow channel structures 10 are spaced apart and connected to the corresponding first flow divider 211 and second flow divider 212. This facilitates assembly and forms a gap between the two flow channel structures 10, which helps to reduce the weight of the entire radiator 100 and lower costs while ensuring the formation of a fluid loop.

[0034] In other embodiments, a flow channel structure 10 can also be provided, which is connected to the first flow divider 211 and the second flow divider 212 respectively, thereby reducing the number of assembly steps. Of course, the number of flow channel structures 10 is not specifically limited in this application, as long as they can be connected to the first flow divider 211 and the second flow divider 212 to form a reciprocating fluid loop.

[0035] like Figures 1 to 3 As shown, in some specific embodiments, in the first distributor 211, along the first direction, at the middle position of each flow channel structure 10, the first distributor 211 is provided with a corresponding separator 22. This arrangement allows the two separators 22 to divide the distribution chamber 2101 of the first distributor 211 into two equally sized side sub-cavities 21011, and the space of the formed middle sub-cavity 21011 is greater than twice the space of one side sub-cavity 21011. This arrangement ensures that the flow rate at the fluid inlet 101 and the flow rate at the fluid outlet 102 remain consistent. Simultaneously, the larger space in the middle sub-cavity 21011 of the first distributor 211 facilitates sufficient buffering of the coolant within the middle sub-cavity 21011, slowing the flow velocity and reducing turning impact.

[0036] like Figures 1 to 3 As shown, in a specific embodiment, in the second diverter 212, along the first direction, the separator 22 is disposed between the two flow channel structures 10 to ensure that it is staggered with the separator 22 in the first diverter 211 to form a reciprocating fluid loop.

[0037] In a more specific embodiment, in the second diverter 212, along the first direction, the separator 22 is located at the middle position of the second diverter 212 to divide the diversion chamber 2101 of the second diverter 212 into two equal-spaced sub-cavities 21011, thereby promoting the consistency of fluid flow rate and velocity in the second diverter 212.

[0038] In other embodiments, each flow divider 2101 is provided with a separator 22, and the fluid inlet 101 and the fluid outlet 102 are located on opposite sides of the radiator 100. That is, the first flow divider 211 is provided with a separator 22, and the second flow divider 212 is also provided with a separator 22. The two separators 22 are staggered and can also form a reciprocating fluid loop.

[0039] In more embodiments, different reciprocating loops can be formed by setting the number of separators 22, and a corresponding number of valves 40 can be set. The fluid inlet 101 and the fluid outlet 102 are located on the same side of the radiator 100, so that the coolant in the middle loop can enter the drain chamber 2111 through the valve 40 to be discharged from the radiator 100.

[0040] like Figures 1 to 5 As shown, in a specific embodiment, the radiator 100 further includes an inlet connector 31 and an outlet connector 32. The inlet connector 31 is fitted to the fluid inlet 101 to facilitate connection to the input pipeline, and the outlet connector 32 is fitted to the fluid outlet 102 to facilitate connection to the output pipeline.

[0041] like Figures 1 to 3 As shown, in a specific embodiment, multiple sub-channels 11 are integrally formed without the need for assembly to form the channel structure 10, which helps to improve structural strength and enhance resistance to fluid impact. For example, the channel structure 10 also includes a heat sink 12, within which multiple spaced sub-channels 11 are formed.

[0042] This application also provides an energy storage converter, including the aforementioned radiator 100, to dissipate heat from the energy-consuming components in the energy storage converter and maintain its long-term operation. Simultaneously, the coordinated arrangement of the flow channel structure 10 and the flow splitting structure 20 in the radiator 100 reduces assembly complexity, saves production time, and helps to save more costs. Furthermore, by placing the fluid inlet 101 and fluid outlet 102 at the bottom of the radiator 100, and through the cooperation of the valve 40 and the drain chamber 2111, the coolant in the central sub-cavity 21011 of the first flow splitter 211 can be quickly and conveniently discharged from the drain chamber 2111 to the fluid outlet 102 and fluid inlet 101, and discharged from the radiator 100 together with the coolant in the side sub-cavities 21011, facilitating subsequent inspection and maintenance.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
