Abstract
Description
Technical Field
[0001] This utility model belongs to the field of heat dissipation devices, specifically relating to an aluminum heat sink with cooling water channels. Background Technology
[0002] As a core component in the field of heat exchange, heat sinks are widely used in heat dissipation scenarios of electronic equipment, power machinery and industrial equipment. Traditional heat sinks usually adopt an integrated cooling water channel design, which realizes the synergistic effect of heat conduction and liquid cooling through the embedded circulation pipes in the metal substrate. Aluminum has become the mainstream material for heat sink manufacturing due to its excellent thermal conductivity, lightweight and cost advantages.
[0003] Traditional heat sinks with cooling channels typically employ a one-piece structure, such as aluminum extrusion or die-cast heat sinks. The cooling channels are directly machined onto the aluminum block. This structure offers high heat dissipation efficiency and structural stability. However, the one-piece cooling channels cannot be disassembled. After long-term use, scale buildup due to water impurities and oxidation can lead to reduced channel diameter, increased thermal resistance, and a significant decrease in heat dissipation efficiency. Cleaning requires chemical cleaning or high-pressure flushing equipment, which is complex and can easily damage the inner walls of the channels, affecting the lifespan of the heat sink. After long-term use, the one-piece cooling channels are prone to blockage or leakage due to scale buildup, corrosion, or mechanical damage. Since the channels are integrally formed with the heat sink body, maintenance requires replacing the entire heat sink, resulting in high maintenance costs and time-consuming processes. It also necessitates shutting down the entire cooling system for cleaning or replacement. Utility Model Content
[0004] To overcome the problem that aluminum heat sinks are difficult to clean and maintain during use, thus increasing maintenance costs and time, an aluminum heat sink with cooling channels is proposed.
[0005] The technical solution of this utility model is as follows: an aluminum heat sink with cooling channels, including a base and a heat sink plate. A first fin is fixedly connected to the upper end of the heat sink plate. A first groove is formed at the upper end of the first fin, with equal front-to-back spacing. A first partition is fixedly connected to the upper end of the first fin. The lower end of the first partition is attached to the upper end of the first fin and the inner wall of the first groove. A second fin is installed on the upper side of the first fin. A second groove is formed at the lower end of the second fin, with equal front-to-back spacing. The second groove corresponds one-to-one with the first groove. A second partition is fixedly connected to the lower end of the second fin. The upper end of the second partition is attached to the lower end of the second fin and the inner wall of the second groove. The upper end of the first partition is attached to the lower end of the second partition. A cooling pipe is provided between the first partition and the second partition, with equal front-to-back spacing. The outer wall of the cooling pipe is attached to the inner wall of the first partition and the second partition.
[0006] Furthermore, the heat sink is fixed to the inner wall of the base, and a fixing frame is provided on the upper side of the base, with a second fin fixed to the inner wall of the fixing frame.
[0007] Furthermore, slots are provided at the four corners of the upper end of the fixed frame, and the lower inner walls of the four slots are provided with first screw holes.
[0008] Furthermore, four support columns, distributed front to back and symmetrical left to right, are fixed to the upper end of the base, and a second screw hole is opened at the center of the upper end of each support column.
[0009] Furthermore, the lower end of the fixing frame is attached to the upper end of the support column, and the first screw hole and the second screw hole correspond one-to-one.
[0010] Furthermore, a screw is threaded into the first screw hole, and the screw passes through the first screw hole and is threaded into the second screw hole.
[0011] Furthermore, symmetrical mounting blocks are fixed to the left and right ends of the base, and mounting holes are provided through the upper end of the mounting blocks.
[0012] Furthermore, a circulating water pump is installed on the rear side of the base. The inlet and outlet of the circulating water pump are both fixedly connected to circulating pipes. The ends of the two circulating pipes are each equipped with a diverter head. Each diverter head is connected to the two ends of the corresponding cooling pipe through a detachable connector pipe to form a sealed connection.
[0013] The beneficial effects of this utility model are as follows: The heat from the heat sink can be dissipated by the first fin and transferred to the second fin. The first and second grooves at the upper and lower ends of the first and second fins provide installation space for the cooling pipe. The first and second partitions can be attached and clamped to hold and fix the cooling pipe, and can conduct the heat from the first and second fins to the outer wall of the cooling pipe, so that the coolant flowing in the cooling pipe can carry away the heat transferred by the heat sink. The cooling pipe can be disassembled by being clamped and fixed by the first and second partitions. Compared with the existing aluminum heat sink, the added cooling pipe structure can be clamped and fixed by the first and second partitions. When maintenance is required, the cooling pipe can be easily removed by disassembling the second fin, which facilitates the maintenance and replacement of the cooling pipe.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figures 1-5 This utility model provides an embodiment: an aluminum heat sink with cooling channels, including a base 1 and a heat sink 3. A first fin 6 is fixedly connected to the upper end of the heat sink 3. The upper end of the first fin 6 has a first groove 7 evenly distributed front and rear. A first partition 8 is fixedly connected to the upper end of the first fin 6. The lower end of the first partition 8 is attached to the upper end of the first fin 6 and the inner wall of the first groove 7. A second fin 9 is installed on the upper side of the first fin 6, and the lower end of the second fin 9 has a... A second tank 10 with equal front and rear spacing is provided, and the second tank 10 corresponds one-to-one with the first tank 7. The lower end of the second fin 9 is fixedly connected to a second partition 11, and the upper end of the second partition 11 is attached to the lower end of the second fin 9 and the inner wall of the second tank 10. The upper end of the first partition 8 is attached to the lower end of the second partition 11. A cooling pipe 2 with equal front and rear spacing is provided between the first partition 8 and the second partition 11, and the outer wall of the cooling pipe 2 is attached to the inner wall of the first partition 8 and the second partition 11.
[0022] The heat from the heat sink 3 can be dissipated and transferred to the second fin 9 through the first fin 6. The first groove 7 and the second groove 10 opened at the upper end of the first fin 6 and the lower end of the second fin 9 can provide installation space for the cooling pipe 2. The first partition 8 and the second partition 11 can be attached and clamped to hold and fix the cooling pipe 2, and can conduct the heat from the first fin 6 and the second fin 9 to the outer wall of the cooling pipe 2, so that the coolant flowing in the cooling pipe 2 can carry away the heat transferred by the heat sink 3. The cooling pipe 2 can be disassembled through the clamping and fixing by the first partition 8 and the second partition 11, so as to facilitate the replacement and maintenance of the cooling pipe 2 and reduce maintenance time and cost.
[0023] Please see Figures 2-4In this embodiment, the heat sink 3 is fixed to the inner wall of the base 1. The upper side of the base 1 is provided with a fixing frame 12. The inner wall of the fixing frame 12 is fixed with a second fin 9. In use, the heat sink 3 can be fixed by the base 1 to fix the heat sink 3 in the position where heat dissipation is required. The fixing frame 12 can be used to install the second fin 9. The upper four corner edges of the fixing frame 12 are provided with slots 13. The lower inner wall of each of the four slots 13 is provided with a first screw hole 14. In use, by providing the first screw hole 14 through the slot 13, the screw head of the screw 15 can be easily hidden, saving installation space.
[0024] Please see Figure 4 In this embodiment, four support columns 16, distributed front to back and symmetrical left to right, are fixed to the upper end of the base 1. A second screw hole 17 is provided at the center of the upper end of the support column 16. In use, the support column 16 can support the fixing frame 12, so that the first partition 8 is attached to the second partition 11 and the lower end of the fixing frame 12 is attached to the upper end of the support column 16. The first screw hole 14 and the second screw hole 17 correspond one-to-one. In use, the installation position of the fixing frame 12 can be easily positioned by the one-to-one correspondence of the first screw hole 14 and the second screw hole 17.
[0025] Please see Figures 2-5 In this embodiment, a screw 15 is threaded into the first screw hole 14. The screw 15 passes through the first screw hole 14 and is threaded into the second screw hole 17. During use, the screw 15 can limit and fix the fixing frame 12 to the base 1, thereby installing the second fin 9 on the first fin 6. This improves the stability of the second fin 9 during operation and facilitates the disassembly of the second fin 9, thus facilitating the replacement and maintenance of the cooling pipe 2. The left and right ends of the base 1 are fixed with symmetrical mounting blocks 18. The upper end of the mounting block 18 has a through mounting hole 19. During use, the mounting block 18 can be easily installed through the through mounting hole 19. The base 1 is fixedly installed in the position where heat dissipation is required to ensure the stability of the heat sink 3 during operation. A circulating water pump 4 is installed on the rear side of the base 1. The inlet and outlet of the circulating water pump 4 are both fixedly connected to the circulating pipes 20. The ends of the two circulating pipes 20 are each equipped with a diverter head 5. Each diverter head 5 is connected to the two ends of the corresponding cooling pipe 2 through a detachable connector pipe to form a sealed connection. In use, the circulating water pump 4 can drive the coolant in the circulating pipes 20 to circulate and move. The diverter head 5 can evenly distribute the liquid to all the cooling pipes 2, so that the coolant passes through the cooling pipes 2 evenly, thereby removing the heat from the first fin 6 and the second fin 9, achieving the effect of rapid heat dissipation.
[0026] During operation, the heat sink 3 can be attached to the heat-generating element and conduct heat to the first fin 6 and the second fin 9. The first fin 6 and the second fin 9 can dissipate heat and conduct heat evenly to the cooling pipe 2. The circulating water pump 4 drives the coolant to circulate in the circulating pipe 20. When the coolant passes through the cooling pipe 2, it can carry away the heat of the first fin 6 and the second fin 9, thereby achieving efficient heat dissipation.
[0027] During maintenance, first, loosen the four screws 15 by turning them. After removing the screws 15, pull upwards to remove the fixing frame 12. Next, turn off the circulating water pump 4 and the circulating pipe 20, and disconnect the connecting pipe between the cooling pipe 2 and the distributor head 5. Then, remove the cooling pipe 2 for maintenance or replacement. After maintenance, place the cooling pipe 2 in the groove of the first partition 8, adjust the position of the cooling pipe 2, press down the second fin 9, and align the first screw hole 14 with the second screw hole 17. Turn the screw 15 so that the screw 15 passes through the first screw hole 14 and is threaded into the second screw hole 17, thus completing the maintenance of the cooling pipe 2.
[0028] Through the above steps, the first fin 6 can dissipate heat from the heat sink 3 and transfer it to the second fin 9. The first groove 7 and the second groove 10 opened at the upper end of the first fin 6 and the lower end of the second fin 9 can provide installation space for the cooling pipe 2. The first partition 8 and the second partition 11 can be attached and clamped to hold and fix the cooling pipe 2, and can conduct the heat of the first fin 6 and the second fin 9 to the outer wall of the cooling pipe 2, so that the coolant flowing in the cooling pipe 2 can carry away the heat transferred by the heat sink 3. The cooling pipe 2 clamped and fixed by the first partition 8 and the second partition 11 can be disassembled, which solves the problem that the cooling water channel of aluminum heat sink is not easy to clean and maintain during use, thereby increasing the maintenance cost and time of the heat sink.
