Description

Technical Field

[0001] This utility model relates to the field of circulating water cooling technology, and in particular to a circulating water cooling system for a power controller. Background Technology

[0002] A power controller is a device used to manage, regulate, and optimize power supply and consumption. Its main function is to ensure the stability and efficiency of the power system. It is commonly used in various power systems, industrial equipment, and household appliances. In power controllers, circulating water cooling systems are often used for thermal management of the equipment, especially in high-power power equipment that operates under high load for extended periods.

[0003] Existing technologies commonly use air cooling and water cooling. Air cooling relies on airflow to remove heat from the device, usually achieved through a combination of a fan and a heat sink. Water cooling technology utilizes the high specific heat capacity and good thermal conductivity of water to absorb and remove the heat generated by the device, and is commonly found in high-power devices.

[0004] In the prior art, the heat dissipation system of power controllers usually uses air cooling or water cooling. Air cooling relies on air flow, and its heat dissipation efficiency is affected by factors such as ambient temperature and air flow rate. Especially in high-power equipment, it cannot effectively remove a large amount of heat. Traditional water cooling systems are prone to problems such as blockage and corrosion. Therefore, a circulating water cooling system for power controllers is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a circulating water cooling system for a power controller, which aims to improve the low fluidity and heat exchange efficiency of the coolant in the prior art, while also increasing the difficulty of system maintenance.

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

[0007] A circulating water cooling system for a power controller includes a cabinet. A support plate is fixedly connected to the inner wall of the cabinet. A power controller housing is fixedly connected to the top of the support plate. A water storage component is fixedly connected to the bottom inner wall of the cabinet. A U-shaped coil is fixedly connected to one end of the water storage component. A heat exchange coil is fixedly connected to the other end of the U-shaped coil. A nozzle is fixedly connected to the bottom of the heat exchange coil. A heat sink is fixedly connected to the top of the heat exchange coil. Two fans are fixedly connected to the top of the cabinet. A heat dissipation box is fixedly connected to the inner wall of the cabinet. An isolation plate is fixedly connected to the inner wall of the heat dissipation box. A packing block is fixedly connected to the inner wall of the heat dissipation box. A second heat sink is fixedly connected to the rear end of the power controller housing. The rear end of the second heat sink contacts one side of the U-shaped coil. A filter component is fixedly connected to the bottom of the heat dissipation box.

[0008] Furthermore, when the power controller is running, the heat generated is transferred to the coolant through heat sink 2. A pump draws coolant from the tank and delivers it to the heat exchange coil, which is in close contact with the power controller housing to absorb heat. The hot coolant flows into the heat exchange coil, where it exchanges heat with the cool air, causing the coolant temperature to drop. Nozzles at the bottom of the heat exchange coil evenly spray the coolant onto heat sink 1, further enhancing heat exchange efficiency, and the fan accelerates heat dissipation. The cooled coolant is guided by the packing blocks and isolation plates in the heat sink box, flowing orderly to the filter assembly to remove impurities before returning to the tank through water pipes, completing the circulation. The entire system effectively improves heat dissipation efficiency, keeps the coolant clean, and ensures stable operation of the equipment over a long period.

[0009] As a further description of the above technical solution:

[0010] The water storage assembly includes a water tank, the exterior of which is fixedly connected to the inner wall of the cabinet, and a pump is fixedly connected to the top of the water tank. The output end of the pump is fixedly connected to the end of the U-shaped coil away from the heat exchange coil.

[0011] Furthermore, the water tank in the water storage assembly stores coolant, and the extraction pump draws the coolant from the tank using negative pressure and delivers it to the loop coil. The coolant flows through the loop coil, absorbing heat generated by the power controller, and then flows to the heat exchange coil for further cooling. This circulation of coolant maintains system heat dissipation, ensuring stable operation of the power controller.

[0012] As a further description of the above technical solution:

[0013] The filter assembly includes a connecting pipe, the top of which is fixedly connected to the bottom of the heat sink, a filter box is fixedly connected to the bottom of the connecting pipe, a filter plate is slidably connected to the front end of the filter box, and a groove is provided on the top of the filter plate.

[0014] Furthermore, the filter assembly guides the coolant to the filter box via connecting pipes. After the liquid flows in, the filter plates effectively intercept impurities, ensuring the coolant's cleanliness. The filter plates are connected to the filter box via sliding grooves for easy removal and cleaning. The cleaned coolant returns to the system through connecting pipes, completing the circulation, maintaining cooling efficiency, and preventing system blockage.

[0015] As a further description of the above technical solution:

[0016] A water pipe is fixedly connected to the left end of the filter box, and the other end of the water pipe is fixedly connected to one side of the water box. A one-way valve is installed on the top of the water pipe.

[0017] Furthermore, the left end of the filter box sends the filtered coolant back to the water tank through a water pipe. A one-way valve ensures that the coolant can only flow in one direction, preventing backflow and maintaining stable system operation. The filtered coolant flows back to the water tank through the water pipe, ready for the next cycle, ensuring that the coolant is clean and can continuously and efficiently dissipate heat.

[0018] As a further description of the above technical solution:

[0019] A rotating rod is rotatably connected to the inner wall of the filter box. A locking block is fixedly connected to the bottom of the rotating rod. A rotating plate is rotatably connected to the top of the rotating rod. A locking plate is fixedly connected to one side of the rotating plate. The outside of the locking plate engages with the top slot of the filter box.

[0020] Furthermore, the rotating rod on the inner wall of the filter box, through rotation, causes the rotating plate to move the locking block and locking plate, thereby loosening or fixing the filter plate. The locking plate engages with the slot at the top of the filter box to ensure the filter plate is securely fixed. When the filter plate needs cleaning, the user rotates the rotating rod to loosen the filter plate, making it easy to remove and clean, simplifying the maintenance process and ensuring the continuous and effective operation of the filtration system.

[0021] As a further description of the above technical solution:

[0022] The front end of the cabinet is rotatably connected to a cabinet door, and the bottom of the fan is fixedly connected to the top of the heat sink.

[0023] Furthermore, the cabinet is easily opened via the cabinet door, and the cooling effect is improved by using a fan.

[0024] As a further description of the above technical solution:

[0025] The filter box is externally fixedly connected to the bottom inner wall of the cabinet, and the locking block is externally movably connected to the inner wall of the slide groove;

[0026] Furthermore, by fixing the filter box to the cabinet, the clips can restrict the filter plates.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Reference Figures 2 to 3 This utility model provides an embodiment of a circulating water cooling system for a power controller, comprising a cabinet 1. The cabinet 1 provides protection for internal components and maintains the stability of the overall structure, thereby ensuring the long-term reliable operation of the equipment. A support plate 2 is fixedly connected to the inner wall of the cabinet 1; the support plate 2 provides a solid support foundation for the installation of the power controller housing 3, further improving the overall structural strength. The power controller housing 3 is fixedly connected to the top of the support plate 2; the power controller housing 3 protects the core components of the power controller from damage caused by external environmental factors. A water storage component is fixedly connected to the bottom inner wall of the cabinet 1, providing a storage base for coolant in the circulating water cooling system and serving as the starting point for the entire cooling process.

[0043] One end of the water storage assembly is fixedly connected to a loop coil 25. The loop coil 25 exchanges heat with the flowing coolant, effectively removing the heat generated during the operation of the power controller. The water storage assembly includes a water tank 4, which provides sufficient coolant capacity for the entire system, ensuring long-term continuous operation. The water tank 4 is externally fixedly connected to the inner wall of the cabinet 1. This design not only saves internal space but also makes the position of the water tank 4 more stable. A pump 5 is fixedly connected to the top of the water tank 4. The pump 5 generates negative pressure to transport the coolant in the water tank 4 to the far end of the loop coil 25, ensuring the flow of the coolant. The output end of the pump 5 is fixedly connected to the end of the loop coil 25 away from the heat exchange coil 6. Through this connection, the coolant can flow smoothly into the heat exchange coil 6 for further heat exchange. Both sides of the front end of the water tank 4 are fixedly connected to add and drain pipes for adding and draining coolant. The design of the add and drain pipes improves the convenience of operation and ensures the simplicity of system maintenance.

[0044] Specifically, the loop coil 25 directly contacts the high-temperature components of the power controller, rapidly removing heat through the flow of coolant. The cooled coolant, after absorbing heat, is then transported to the heat exchange coil 6 for further heat exchange, further reducing the liquid temperature. The addition and replacement pipes at the front end of the water tank 4 facilitate coolant addition and replacement, ensuring simple and quick maintenance while effectively improving the system's lifespan and operational stability. This system design enables continuous and efficient coolant circulation, effectively removing the heat generated during equipment operation through the heat exchange process of the loop coil 25 and the heat exchange coil 6, thus ensuring the power controller's heat dissipation performance and stable operation.

[0045] refer to Figure 3 The other end of the U-shaped coil 25 is fixedly connected to a heat exchange coil 6. The heat exchange coil 6 exchanges heat with the circulating coolant, effectively reducing the coolant temperature and ensuring subsequent heat dissipation. A nozzle 7 is fixedly connected to the bottom of the heat exchange coil 6, which can evenly spray coolant onto the top of the heat sink 8, thereby improving heat dissipation. The top of the heat exchange coil 6 is fixedly connected to the heat sink 8; the heat sink 8, with its large surface area, further accelerates heat diffusion, improving overall heat dissipation efficiency. Two fans 9 are fixedly connected to the top of the cabinet 1; the fans 9 remove heat from the heat sink 8 through forced convection, thereby improving the speed and effect of heat dissipation. A heat sink 10 is fixedly connected to the inner wall of the cabinet 1; the heat sink 10 improves the utilization efficiency of the cooling air provided by the fans 9 by limiting the airflow path. An isolation plate 12 is fixedly connected to the inner wall of the heat sink 10; the isolation plate 12 restricts the water flow in the air duct, making the coolant flow more orderly and reducing heat accumulation. A packing block 11 is fixedly connected to the inner wall of the heat sink 10. The packing block 11 improves the water cooling efficiency by increasing the contact time between the coolant and the air. A second heat sink 13 is fixedly connected to the rear end of the power controller housing 3. The second heat sink 13 transfers heat from inside the housing to the coolant by directly contacting one side of the U-shaped coil 25. The rear end of the second heat sink 13 contacts one side of the U-shaped coil 25. In this way, heat can be quickly conducted to the coolant, thereby effectively reducing the system temperature.

[0046] Specifically, after absorbing heat from the coil 25, the coolant enters the heat exchange coil 6, where further heat exchange effectively reduces the coolant temperature, laying the foundation for subsequent heat dissipation. A nozzle 7 is connected to the bottom of the heat exchange coil 6, which evenly sprays the coolant onto the top of the heat sink 8. The large surface area of ​​the heat sink 8 allows for rapid heat dissipation, and the top fan 9 provides forced convection, significantly improving heat dissipation speed and efficiency. The operation of the fan 9 causes cool air to pass over the surface of the heat sink 8, quickly removing heat from the fins through forced convection, while maximizing the heat dissipation effect in the sprayed area. The heat sink 10 optimizes the airflow provided by the fan 9 using an internally defined airflow path, improving heat dissipation efficiency. Furthermore, the baffle 12 inside the heat sink 10 diverts and restricts the coolant flow, ensuring orderly flow and preventing heat accumulation in localized areas. The packing block 11 inside the heat sink 10 further optimizes the heat dissipation effect. By increasing the contact time between the coolant and air, the packing block 11 significantly improves the efficiency of water cooling. Meanwhile, a second heat sink 13 is installed at the rear end of the power controller housing 3. The second heat sink 13 directly contacts one side of the U-shaped coil 25, quickly transferring the heat inside the power controller housing 3 to the flowing coolant. Through the close contact between the second heat sink 13 and the U-shaped coil 25, the heat can be quickly absorbed and carried away by the coolant, further reducing the system temperature.

[0047] refer to Figure 1 , Figure 4 and Figure 5 A filter assembly is fixedly connected to the bottom of the heat sink 10. The filter assembly ensures the cleanliness of the coolant during circulation, thereby preventing system blockage. The filter assembly includes a connecting pipe 14, which guides the coolant from the bottom of the heat sink 10 into the filter box 15, providing a channel for subsequent filtration. The filter box 15 is fixedly connected to the bottom of the connecting pipe 14; the filter box 15 is the core component of the entire system for treating coolant impurities, ensuring the purity of the coolant. A filter plate 18 is slidably connected to the front end of the filter box 15; the filter plate 18 can effectively intercept impurities in the coolant, improving the quality of the coolant. A groove 19 is provided on the top of the filter plate 18; the groove 19 facilitates the removal and installation of the filter plate 18, thereby simplifying maintenance operations. A cabinet door 24 is rotatably connected to the front end of the cabinet 1.

[0048] refer to Figures 4 to 6A water pipe 16 is fixedly connected to the left end of the filter box 15. The water pipe 16 is used to return the filtered coolant to the water tank 4, completing the coolant circulation. The other end of the water pipe 16 is fixedly connected to one side of the water tank 4; this connection method ensures that the coolant can smoothly return to the water tank 4, preparing for the next circulation. A one-way valve 17 is installed at the top of the water pipe 16. The one-way valve 17 ensures the stable operation of the cooling circulation system by preventing the backflow of coolant. A rotating rod 20 is rotatably connected to the inner wall of the filter box 15. The rotating rod 20, through its rotatable design, makes it easy for the user to adjust the position of the filter assembly. A locking block 21 is fixedly connected to the bottom of the rotating rod 20. The locking block 21, through its cooperation with the slide groove 19, securely fixes the filter plate 18 in the filter box 15. A rotating plate 22 is rotatably connected to the top of the rotating rod 20; the rotating plate 22 allows the user to easily operate the rotating rod 20 for maintenance of the filter assembly. A clamping plate 23 is fixedly connected to one side of the rotating plate 22; the clamping plate 23 ensures the stability of the filter assembly by engaging with the slot at the top of the filter box 15.

[0049] Specifically, the left end of the filter box 15 is connected to the water tank 4 via a water pipe 16. The filtered coolant returns to the water tank 4 through the water pipe 16, completing the coolant circulation process. The connection method of the water pipe 16 ensures that the coolant can smoothly flow back to the water tank 4 for the next cycle. A one-way valve 17 is installed at the top of the water pipe 16. The function of the one-way valve 17 is to prevent backflow of coolant, ensuring that the flow direction of coolant is always correct, avoiding coolant backflow in the system, and ensuring stable system operation. For easy maintenance and operation, a rotating rod 20 is rotatably connected to the inner wall of the filter box 15. The rotating rod 20 allows the position of the filter assembly to be adjusted as needed. A locking block 21 is fixedly connected to the bottom of the rotating rod 20. The cooperation between the locking block 21 and the sliding groove 19 ensures that the filter plate 18 is firmly fixed in the filter box 15, preventing it from loosening or shifting. A rotating plate 22 is connected to the top of the rotating rod 20. The user can easily adjust the rotating rod 20 through the rotating plate 22, thereby loosening the filter plate 18 for easy removal and cleaning. A retaining plate 23 is fixedly connected to one side of the rotating plate 22. The retaining plate 23 engages with the slot at the top of the filter box 15, making the installation of the filter assembly more stable and preventing it from loosening during use.

[0050] Working principle: When the equipment generates heat during operation, the pump 5 draws coolant from the water tank 4 and delivers it to the coil 25. The coil 25 is in close contact with the heat sink 13 inside the power controller housing 3. When the coolant flows through it, it can quickly absorb the heat conducted by the surface of the heat sink 13. The coolant, after absorbing heat, flows further into the heat exchange coil 6. The top of the heat exchange coil 6 is equipped with a heat sink 8, which works in conjunction with the fan 9 to rapidly diffuse the heat into the air using forced convection.

[0051] After being sprayed, the coolant drips down to the bottom of the heat sink 10. The baffle plate 12 installed inside the heat sink 10 can guide the liquid to flow in an orderly manner, avoid coolant accumulation, and improve the consistency of heat dissipation. At the same time, the filler block 11 slows down the flow rate of the coolant and increases its contact time with the cold air, thereby further improving the cooling effect. After the coolant accumulates at the bottom of the heat sink 10, it flows into the filter assembly through the connecting pipe 14.

[0052] In the filtration assembly, coolant enters the filter box 15, where a slidingly installed filter plate 18 effectively intercepts impurities in the liquid, ensuring that the coolant in the system remains clean and preventing blockages in the cooling circuit. The filtered coolant returns to the water tank 4 via the water pipe 16, completing a full cycle. In addition, a rotating rod 20 and a rotating plate 22 are installed inside the filter box 15. Users can loosen the filter plate 18 by rotating the rotating plate 22, making it easy to remove the filter plate 18 for cleaning and ensuring the continuity of the filtration effect.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
