Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for new energy controllers, and in particular to an integrated heat dissipation water channel for new energy controllers. Background Technology

[0002] The integrated controller of new energy vehicles contains a large number of modules, which will accumulate a lot of heat when it is working. If this heat is not dissipated in time, it will affect the normal operation of the modules.

[0003] A search revealed Chinese utility model patent CN213586786U, which discloses a heat dissipation channel structure for a motor controller. The structure includes a substrate with an inlet pipe and an outlet pipe welded to both ends. The inlet and outlet pipes extend along the width of the substrate and connect to an external cooling system. Two layers of heat dissipation pipe assemblies are arranged on the top of the substrate, between the inlet and outlet pipes. Each heat dissipation pipe assembly includes multiple capillary tubes arranged at equal intervals, with both ends of the capillary tubes welded to and connected to the inlet and outlet pipes, respectively. Multiple mounting holes are formed on the substrate on both sides of the heat dissipation pipe assembly.

[0004] Based on existing technologies, the aforementioned patent has the following shortcomings: when the capillary tubes installed on the outer wall of the controller dissipate heat, the water temperature in the capillary tubes near the inlet pipe is much lower than that in the capillary tubes near the outlet pipe, resulting in uneven cooling of the entire controller. Therefore, there is an urgent need for an integrated cooling water channel for new energy controllers to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated cooling water channel for new energy controllers. Its advantages include: the ability to exchange heat with the controller body, thereby cooling the controller body and ensuring it remains in a suitable working environment for extended periods; and the serpentine distribution of the circulation pipes on the outer wall of the controller body effectively extends the length of the cooling water circulation pipes on the controller body surface, thus prolonging the cooling time of the controller body by the cooling water in the circulation pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated cooling water channel for a new energy controller includes a circulation pipe, which is fixedly connected to the outer wall of the controller body. An inlet pipe and an outlet pipe are fixedly connected to both ends of the circulation pipe, and both the inlet pipe and the outlet pipe are connected to the circulation pipe.

[0008] Through the above technical solution: cooling water is delivered to the inside of the circulation pipe through the inlet pipe. At the same time, the circulation pipe is fixedly connected to the outer wall of the controller body. During the process of cooling water flowing through the circulation pipe, it can exchange heat with the controller body, thereby achieving the cooling of the controller body and ensuring that the controller body can be in a suitable working environment for a long time.

[0009] The present invention is further configured such that the circulation tube is distributed in a serpentine pattern on the outer wall of the controller body.

[0010] The above technical solution effectively extends the length of the cooling water circulation pipe on the surface of the controller body, thereby extending the cooling time of the controller body by the cooling water in the circulation pipe.

[0011] The present invention is further configured such that the inner diameter of the inlet pipe is smaller than the inner diameter of the outlet pipe.

[0012] The above technical solutions can effectively prevent pipe bursts caused by excessive water pressure in the circulation pipe.

[0013] The present invention is further configured such that a thickening plate is provided inside the circulation tube, so that the circulation tube is filled with a thickening plate.

[0014] The above technical solutions enable the circulation pipe to cool the controller body relatively evenly.

[0015] The present invention is further configured such that the thickness of the thickening plate gradually increases in the direction away from the water inlet pipe.

[0016] The above technical solution ensures that the flow rate of cooling water in the circulation pipe near the inlet pipe is greater than that in the direction away from the inlet pipe, effectively preventing the cooling water in the circulation pipe from heating up too quickly.

[0017] The present invention is further configured such that a heat sink is fixedly connected to the top outer wall of the circulation pipe.

[0018] The above technical solutions can effectively improve the heat dissipation efficiency of the circulation tube, and further enhance the heat dissipation effect of the circulation tube on the controller body.

[0019] The present invention is further configured such that the width of the heat sink gradually increases along the direction close to the water outlet pipe.

[0020] The above technical solution involves gradually increasing the width of the heat sink along the direction closer to the water outlet pipe, thereby ensuring that the circulation pipe closer to the water outlet pipe cools down faster.

[0021] The present invention is further configured such that a baffle is provided inside the circulation pipe near the outlet pipe, and the baffle is inclined inside the circulation pipe.

[0022] The above technical solutions extend the flow path of cooling water in the downstream section of the circulation pipe.

[0023] The present invention is further configured such that the baffles are fixed at equal intervals on the inner walls of both sides of the circulation pipe, and the baffles on the inner walls of both sides of the circulation pipe are staggered.

[0024] The above technical solutions increase the heat exchange time between the cooling water and the controller body.

[0025] The beneficial effects of this utility model are as follows:

[0026] 1. In this utility model, during the process of cooling water flowing through the circulation pipe, heat exchange can be carried out with the controller body, thereby achieving the cooling of the controller body and ensuring that the controller body can be in a suitable working environment for a long time. At the same time, the circulation pipe is distributed in a serpentine pattern on the outer wall of the controller body, which effectively extends the length of the cooling water circulation pipe on the surface of the controller body, thereby extending the cooling time of the controller body by the cooling water in the circulation pipe.

[0027] 2. In this utility model, the thickness of the thickening plate in the circulation pipe gradually increases along the direction away from the water inlet pipe, so that the flow rate of cooling water in the circulation pipe near the water inlet pipe is greater than that in the direction away from the water inlet pipe. This effectively avoids the cooling water in the circulation pipe from heating up too quickly, which would result in poor cooling effect of the cooling water in the circulation pipe away from the water inlet pipe on the controller body. This allows the circulation pipe to cool the controller body relatively evenly.

[0028] 3. In this utility model, the heat sink at the top of the circulation pipe effectively improves the heat dissipation efficiency of the circulation pipe during the heat dissipation process of the controller body. This further enhances the heat dissipation effect of the circulation pipe on the controller body. At the same time, the width of the heat sink gradually increases along the direction closer to the outlet pipe, thereby ensuring that the circulation pipe cools down faster towards the outlet pipe and avoiding the occurrence of high cooling water temperature in the circulation pipe near the outlet pipe.

[0039] Example 1

[0040] Reference Figures 1-2An integrated cooling water channel for a new energy controller includes a circulation pipe 2, which is fixedly connected to the outer wall of the controller body 1. The two ends of the circulation pipe 2 are respectively fixedly connected to an inlet pipe 3 and an outlet pipe 4. Both the inlet pipe 3 and the outlet pipe 4 are connected to the circulation pipe 2. Cooling water is transported to the inside of the circulation pipe 2 through the inlet pipe 3. At the same time, the circulation pipe 2 is fixedly connected to the outer wall of the controller body 1. During the process of the cooling water flowing through the circulation pipe 2, it can exchange heat with the controller body 1, thereby achieving the cooling of the controller body 1 and ensuring that the controller body 1 can be in a suitable working environment for a long time.

[0041] To further improve the heat dissipation effect of the circulation pipe 2 on the controller body 1, refer to Figures 1-2 The circulation pipe 2 is distributed in a serpentine pattern on the outer wall of the controller body 1, which effectively extends the length of the cooling water circulation pipe 2 on the surface of the controller body 1, thereby extending the cooling time of the cooling water in the circulation pipe 2 on the controller body 1.

[0042] To prevent excessive water pressure in circulation pipe 2 from causing a pipe burst, refer to... Figure 1 The inner diameter of the inlet pipe 3 is smaller than the inner diameter of the outlet pipe 4.

[0043] Example 2

[0044] Reference Figure 3 An integrated cooling water channel for a new energy controller, compared to embodiment 1, further includes a thickening plate 5 inside the circulation pipe 2. The thickness of the thickening plate 5 gradually increases in the direction away from the water inlet pipe 3. This makes the cooling water flow rate in the circulation pipe 2 closer to the water inlet pipe 3 greater than the flow rate away from the water inlet pipe 3, effectively preventing the cooling water in the circulation pipe 2 from heating up too quickly, which would result in poor cooling effect of the cooling water in the circulation pipe 2 away from the water inlet pipe 3 on the controller body 1. This allows the circulation pipe 2 to cool the controller body 1 relatively evenly.

[0045] Example 3

[0046] Reference Figure 4 An integrated heat dissipation channel for a new energy controller is provided. Compared with embodiments 1-2, this embodiment further includes a heat sink 6 fixedly connected to the top outer wall of the circulation pipe 2, which can effectively improve the heat dissipation efficiency of the circulation pipe 2 and further improve the heat dissipation effect of the circulation pipe 2 on the controller body 1.

[0047] To avoid the occurrence of high cooling water temperature in the circulation pipe 2 near the outlet pipe 4, refer to Figure 4The width of the heat sink 6 gradually increases along the direction close to the water outlet pipe 4, thereby ensuring that the circulation pipe 2 near the water outlet pipe 4 cools down faster.

[0048] Example 4

[0049] Reference Figure 5 An integrated heat dissipation water channel for a new energy controller, compared with embodiments 1-3, this embodiment also includes a baffle 7 installed inside the circulation pipe 2 near the outlet pipe 4, and the baffle 7 is installed at an inclination inside the circulation pipe 2.

[0050] To extend the flow path of cooling water in the downstream section of circulation pipe 2, refer to Figure 5 The baffles 7 are fixed at equal intervals on the inner walls of both sides of the circulation pipe 2. The baffles 7 on the inner walls of both sides of the circulation pipe 2 are staggered. The staggered baffles 7 can extend the flow path of the cooling water in the circulation pipe 2, thereby increasing the heat exchange time between the cooling water and the controller body 1.

[0051] Working principle: When in use, the inlet pipe 3 and outlet pipe 4 of the circulation pipe 2 are connected to the external water pipe. At this time, the cooling water is transported to the inside of the circulation pipe 2 through the inlet pipe 3. Meanwhile, the circulation pipe 2 is fixedly connected to the outer wall of the controller body 1. During the process of the cooling water flowing through the circulation pipe 2, it can exchange heat with the controller body 1, thereby achieving the cooling of the controller body 1 and ensuring that the controller body 1 can be in a suitable working environment for a long time. At the same time, the circulation pipe 2 is distributed in a serpentine shape on the outer wall of the controller body 1, which effectively extends the length of the circulation pipe 2 on the surface of the controller body 1, thereby extending the cooling time of the controller body 1 by the cooling water in the circulation pipe 2.

[0052] Meanwhile, the thickness of the thickening plate 5 in the circulation pipe 2 gradually increases in the direction away from the water inlet pipe 3, so that the flow rate of cooling water in the circulation pipe 2 in the direction close to the water inlet pipe 3 is greater than the flow rate in the direction away from the water inlet pipe 3. This effectively avoids the cooling water in the circulation pipe 2 from heating up too quickly, which would result in poor cooling effect of the cooling water in the circulation pipe 2 in the direction away from the water inlet pipe 3 on the controller body 1. This allows the circulation pipe 2 to cool the controller body 1 relatively evenly.

[0053] During the process of cooling the controller body 1 through the circulation pipe 2, the heat sink 6 set on the top of the circulation pipe 2 can effectively improve the heat dissipation efficiency of the circulation pipe 2 and further improve the heat dissipation effect of the circulation pipe 2 on the controller body 1. At the same time, the width of the heat sink 6 gradually increases along the direction close to the outlet pipe 4, thereby ensuring that the circulation pipe 2 close to the outlet pipe 4 cools down faster and avoids the occurrence of high cooling water temperature in the circulation pipe 2 close to the outlet pipe 4.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
