[0033] First Embodiment

[0034] Please refer to the reference. Figures 1 to 4 This utility model provides an integrated heat dissipation device 100 for achieving heat dissipation. It can achieve integrated heat dissipation of multiple heat dissipation components, reducing the size of individual heat dissipation components while ensuring heat dissipation effect, improving reliability, and facilitating disassembly and maintenance, thereby reducing production, installation, and maintenance costs and improving economic efficiency.

[0035] The integrated heat dissipation device 100 includes a first heat sink 110, a second heat sink 120, a first connecting flange 130, a second connecting flange 140, and a flexible connecting pipe 150. The first connecting flange 130 is detachably connected to the first heat sink 110 to facilitate its assembly and disassembly; and / or, the second connecting flange 140 is detachably connected to the second heat sink 120 to facilitate its assembly and disassembly. The flexible connecting pipe 150 connects the first connecting flange 130 and the second connecting flange 140, connecting the first heat sink 110 and the second heat sink 120 and allowing the cooling medium to circulate within them, thus ensuring effective heat dissipation. In this way, the detachable connection between the first heat sink 110 and the second heat sink 120 enables integrated heat dissipation of at least two heat sinks. This reduces the size of a single heat sink while ensuring heat dissipation performance, improves reliability, and allows any heat sink to be removed independently for maintenance. This facilitates disassembly and maintenance, reduces production and installation costs as well as maintenance costs, and improves economic efficiency.

[0036] It should be noted that the flexible connecting pipe 150 has a certain degree of flexibility, capable of undergoing a certain amount of elastic deformation. During assembly and disassembly, it possesses a certain degree of mobility, compressibility, or extensibility in all directions, facilitating the assembly and disassembly of the first heat sink 110 or the second heat sink 120, thereby improving assembly, disassembly, and maintenance efficiency. Furthermore, the flexible connecting pipe 150, with its inherent flexibility, also acts as a shock absorber during the movement and transportation of the integrated heat dissipation device 100, enhancing safety.

[0037] Furthermore, there are multiple first heat sinks 110 and multiple second heat sinks 120. The first heat sink 110 is a radiator or a heat exchanger chamber, and the second heat sink 120 is a radiator. That is, the connection between the first heat sink 110 and the second heat sink 120 is a radiator-to-radiator connection or a heat exchanger chamber-to-radiator connection. Specifically, multiple first heat sinks 110 and multiple second heat sinks 120 together form an integrated heat dissipation device 100. The multiple heat sinks (including the first heat sink 110 and the second heat sink 120) work together to ensure heat dissipation effect and improve heat dissipation efficiency.

[0038] In this embodiment, the first heat sink 110 is a flow collector, and there are two flow collectors. The second heat sink 120 is a radiator, and there are six radiators. The six radiators are divided into three groups, with two radiators in each group interconnected. The three groups of radiators are arranged side-by-side, and two flow collectors are positioned opposite each other on both sides of the six radiators. One end of each of the three groups of radiators is connected to one flow collector, and the other end is connected to another flow collector, facilitating the flow of the cooling medium at any position within the two flow collectors and the six radiators, ensuring effective heat dissipation. However, this is not the only embodiment. In other embodiments, the first heat sink 110 can also be a radiator, and the number of second heat sinks 120 can also be eight. The type and number of the first heat sink 110 and the second heat sink 120 are not specifically limited.

[0039] In this embodiment, there are two first connecting flanges 130, two second connecting flanges 140, and two flexible connecting pipes 150 connected between the first heat sink 110 and the second heat sink 120. The two first connecting flanges 130 are spaced apart along a direction perpendicular to the axial direction of the flexible connecting pipe 150, and are both detachably connected to the first heat sink 110. The two second connecting flanges 140 are spaced apart along a direction perpendicular to the axial direction of the flexible connecting pipe 150, and are both detachably connected to the second heat sink 120. The two flexible connecting pipes 150 are arranged side-by-side, each flexible connecting pipe 150 connecting between one first connecting flange 130 and one second connecting flange 140, to increase the flow cross-sectional area of ​​the cooling medium, thereby ensuring the heat dissipation effect. However, this is not the only option. In other embodiments, the number of the first connecting flange 130, the second connecting flange 140, and the flexible connecting pipe 150 connected between the first heat sink 110 and the second heat sink 120 can be one or three. There is no specific limitation on the number of the first connecting flange 130, the second connecting flange 140, and the flexible connecting pipe 150 connected between the first heat sink 110 and the second heat sink 120.

[0040] Furthermore, the first heat sink 110 has a first through hole (not shown), and the first connecting flange 130 has a first connecting hole 131, with the first through hole communicating with the first connecting hole 131. The second heat sink 120 has a second through hole (not shown), and the second connecting flange 140 has a second connecting hole 141, with the second through hole communicating with the second connecting hole 141. A flexible connecting pipe 150 is simultaneously disposed between the first connecting hole 131 and the second connecting hole 141, with the first through hole communicating with the second through hole through the flexible connecting pipe 150. Specifically, both the first connecting hole 131 and the second connecting hole 141 are used to allow space for the flexible connecting pipe 150, ensuring that the flexible connecting pipe 150 can communicate with the first through hole and the second through hole. This allows the cooling medium in the first heat sink 110 to sequentially enter the second heat sink 120 through the first through hole, the flexible connecting pipe 150, and the second through hole, improving the stability of the cooling medium flow and preventing cooling medium leakage.

[0041] Preferably, the first connecting flange 130 has an annular groove 132 on the side near the first heat sink 110, and the annular groove 132 communicates with the first connecting hole 131. The end of the flexible connecting pipe 150 is provided with an annular flange 151, which is disposed in the annular groove 132. The first connecting flange 130 can limit the flexible connecting pipe 150 through the cooperation of the annular flange 151 and the annular groove 132, so as to fix the relative position of the flexible connecting pipe 150 and the first connecting flange 130 and prevent the flexible connecting pipe 150 from detaching from the first connecting flange 130.

[0042] Furthermore, the integrated heat dissipation device 100 also includes a sealing ring 160. The sealing ring 160 is disposed in the annular groove 132 and sandwiched between the annular flange 151 and the first heat dissipation component 110. The sealing ring 160 is used to seal the gap between the annular flange 151 and the first heat dissipation component 110 to improve the sealing effect and further prevent the leakage of cooling medium.

[0043] In this embodiment, the sealing ring 160 and the annular flange 151 are integrally formed to facilitate manufacturing and processing, save assembly steps, and reduce processing costs. However, this is not the only option. In other embodiments, the sealing ring 160 and the annular flange 151 can be separately provided, with the annular flange 151 pressing the sealing ring 160 onto the first heat sink 110. The connection method between the sealing ring 160 and the annular flange 151 is not specifically limited.

[0044] It should be noted that there is a preset gap 170 between the annular flange 151 and the first heat sink 110. The preset gap 170 is used to fill the gap when the sealing ring 160 undergoes elastic deformation under clamping pressure, so as to realize the function of giving way to the compressed sealing ring 160 and ensuring the reliability of assembly. Specifically, before the first connecting flange 130 is connected to the first heat sink 110, the flexible connecting pipe 150 passes through the first connecting hole 131, and the annular flange 151 is disposed in the annular groove 132 and fits against the bottom wall of the annular groove 132. At this time, the sealing ring 160 protrudes from the annular groove 132, that is, the sealing ring 160 protrudes from the surface of the first connecting flange 130. When the first connecting flange 130 is connected to the first heat sink 110, the surface of the first connecting flange 130 fits against the surface of the first heat sink 110, and the surface of the first heat sink 110 applies pressure to the sealing ring 160, so that the sealing ring 160 undergoes elastic deformation and extends within the preset gap 170. In this way, the sealing ring 160 fills the preset gap 170, which can further improve the sealing effect and prevent the leakage of cooling medium.

[0045] Preferably, the sealing ring 160 is V-shaped and includes a first supporting portion 161, a connecting portion 162, and a second supporting portion 163. The first supporting portion 161 and the second supporting portion 163 are arranged at a preset included angle and are both connected to the connecting portion 162 and abut against the first heat sink 110. The connecting portion 162 is integrally formed with the annular flange 151. When the first connecting flange 130 is connected to the first heat sink 110, the surface of the first heat sink 110 simultaneously applies pressure to the first supporting portion 161 and the second supporting portion 163 to press them downwards simultaneously. During this process, the first supporting portion 161 and the second supporting portion 163 extend in opposite directions within the preset gap 170. In this way, the first supporting portion 161 and the second supporting portion 163 simultaneously fill the preset gap 170 to improve the sealing effect.

[0046] In this embodiment, the first support portion 161, the connecting portion 162, and the second support portion 163 are integrally formed to improve the connection strength.

[0047] In this embodiment, the connection structure between the flexible connecting pipe 150 and the second connecting flange 140 is the same as the connection structure between the flexible connecting pipe 150 and the first connecting flange 130, and will not be described again here.

[0048] Furthermore, both the first connecting flange 130 and the second connecting flange 140 are made of metal or non-metal materials; the flexible connecting pipe 150 is a rubber pipe, a plastic pipe, or a metal pipe with a flexible structure; the shape of the flexible connecting pipe 150 can be a concave pipe, a convex pipe, a straight pipe, or a concave-convex joint pipe.

[0049] In this embodiment, the first heat sink 110 is bolted to the first connecting flange 130, and the second heat sink 120 is bolted to the second connecting flange 140 to ensure connection stability. However, this is not the only embodiment. In other embodiments, the first heat sink 110 can be snapped onto the first connecting flange 130, and the second heat sink 120 can be snapped onto the second connecting flange 140. The connection method between the first heat sink 110 and the first connecting flange 130, and the connection method between the second heat sink 120 and the second connecting flange 140, are not specifically limited.

[0050] The integrated heat dissipation device 100 provided in this embodiment of the present invention has a first connecting flange 130 detachably connected to a first heat dissipation component 110, and / or a second connecting flange 140 detachably connected to a second heat dissipation component 120; a flexible connecting pipe 150 is connected between the first connecting flange 130 and the second connecting flange 140, and the flexible connecting pipe 150 is used to connect the first heat dissipation component 110 and the second heat dissipation component 120. Compared with the prior art, the integrated heat dissipation device 100 provided by the present invention, due to the use of the flexible connecting pipe 150 connected between the first connecting flange 130 and the second connecting flange 140, can realize integrated heat dissipation of multiple heat dissipation components, reduce the volume of a single heat dissipation component while ensuring heat dissipation effect, improve reliability, facilitate disassembly and maintenance, reduce production and installation costs and maintenance costs, and improve economic efficiency.

[0051] Second Embodiment

[0052] Please refer to Figure 5 This utility model embodiment provides an integrated heat dissipation device 100. Compared with the first embodiment, the difference of this embodiment is that the integrated heat dissipation device 100 also includes a limiting reinforcing ring 180.

[0053] In this embodiment, a limiting reinforcing ring 180 is sleeved outside the flexible connecting pipe 150. The axial direction of the limiting reinforcing ring 180 is the same as that of the flexible connecting pipe 150. The limiting reinforcing ring 180 is used to strengthen and limit the flexible connecting pipe 150, thereby extending its service life. Specifically, the cooling medium has pressure during its flow. As the cooling medium flows through the flexible connecting pipe 150, the pressure may cause the flexible connecting pipe 150 to expand or deform, shortening its lifespan. To limit the expansion or deformation of the flexible connecting pipe 150, a limiting reinforcing ring 180 is sleeved around it. This not only improves the strength of the flexible connecting pipe 150 but also limits its expansion or deformation, ensuring safety and reliability.

[0054] In this embodiment, the limiting reinforcing ring 180 and the flexible connecting pipe 150 are integrally formed, and the limiting reinforcing ring 180 is a reinforcing rib or a woven mesh.

[0055] The beneficial effects of the integrated heat dissipation device 100 provided in this embodiment are the same as those in the first embodiment, and will not be repeated here.

[0056] Third Embodiment

[0057] Please refer to Figure 6 This utility model embodiment provides an integrated heat dissipation device 100. Compared with the second embodiment, the difference in this embodiment lies in the different structure of the limiting reinforcing ring 180.

[0058] In this embodiment, the limiting reinforcing ring 180 and the flexible connecting pipe 150 are separately provided. The limiting reinforcing ring 180 is a clamp, which is sleeved on the outside of the flexible connecting pipe 150 to strengthen and limit the flexible connecting pipe 150.

[0059] The beneficial effects of the integrated heat dissipation device 100 provided in this embodiment are the same as those in the first embodiment, and will not be repeated here.

[0060] Fourth embodiment

[0061] Please refer to Figure 7 This utility model embodiment provides an integrated heat dissipation device 100. Compared with the second embodiment, the difference in this embodiment is that the number of limiting reinforcing rings 180 is different.

[0062] In this embodiment, there are multiple limiting reinforcing rings 180, which are arranged in parallel at intervals and are all sleeved on the outside of the flexible connecting tube 150. The multiple limiting reinforcing rings 180 work together to improve the strengthening and limiting effect on the flexible connecting tube 150.

[0063] The beneficial effects of the integrated heat dissipation device 100 provided in this embodiment are the same as those in the first embodiment, and will not be repeated here.

[0064] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
