Description

Technical Field

[0001] The present invention belongs to the technical field of radiators, and more specifically, particularly relates to a fluid-solid coupled radiator and a heat dissipation method. Background Art

[0002] A fluid-solid coupled radiator is a radiator that works by coupling fluid and solid together, aiming to effectively transfer heat from the fluid to the solid and dissipate it. This kind of radiator is usually used in industrial and automotive fields, and can effectively control the temperature of equipment and engines to ensure their normal operation.

[0003] Chinese Patent Publication No.: CN202168317U, a fluid-solid coupled radiator. In this invention, the liquid level of the fluid under normal conditions is not lower than the middle position between the highest point and the lowest point in the cavity in the gravity direction; a heat dissipation component, and the heat dissipation component is arranged on the heat absorption component. This utility model has the advantages of high heat dissipation efficiency and convenient implementation, and can be used in the electronic field.

[0004] Existing fluid-solid coupled radiators have the following disadvantages:

[0005] 1. The fin spacing between existing coupled radiators cannot be adjusted. The design of fins with a fixed spacing may not maximize the heat dissipation surface area, thus limiting the heat transfer efficiency. It cannot be adjusted according to the actual heat dissipation requirements, resulting in certain limitations in its adaptability and being difficult to meet the heat dissipation requirements under different working conditions and operating conditions;

A fixed angle may limit the heat transfer efficiency, cause the fluid flow to be blocked, may reduce the fluid flow performance of the entire system, resulting in increased energy loss and pressure loss, and making the device use more singly.

The heat dissipation mechanism includes a C-shaped fixed frame 4 and heat dissipation fins 5. The adjustment mechanism includes a C-shaped bottom plate 2, a movable plate 3 and a movable block 6. A base 14 is fixedly installed at the lower end of the heat absorption component 1. The C-shaped bottom plate 2 is fixedly installed at the side end of the base 14. The movable plate 3 slides on the upper end of the C-shaped bottom plate 2. The number of C-shaped fixed frames 4 is multiple, and the number of heat dissipation fins 5 is multiple. Each heat dissipation fin 5 is located within the C-shaped fixed frame 4. A first rectangular chute 12 is opened at the upper end of the heat absorption component 1. The number of movable blocks 6 is multiple, and each movable block 6 is slidably installed on the inner side wall of the first rectangular chute 12. A heat source 15 is fixedly installed at the side end of the heat absorption component 1. A square groove 11 is opened at the side end of the heat absorption component 1. Second rectangular chutes 13 are also opened at both end portions of the inner side wall of the first rectangular chute 12. A third rectangular chute 21 is opened at the upper end of the C-shaped bottom plate 2. First circular grooves 22 are penetrated through both end portions of the inner side wall of the third rectangular chute 21. Two fourth rectangular chutes 23 are opened at the upper end of the C-shaped bottom plate 2. Two movable rods 31 are fixedly installed at the lower end of the movable plate 3, and the two movable rods 31 are respectively slidably installed on the inner side walls of the two fourth rectangular chutes 23. A plurality of inclined grooves 32 are penetrated through the upper end of the movable plate 3. A sliding rod 33 is fixedly installed at the lower end of the movable plate 3, and the sliding rod 33 is slidably installed on the inner side wall of the third rectangular chute 21. A first threaded groove 34 is penetrated through the side end of the sliding rod 33. The same first threaded rod 35 is rotatably installed on the inner side walls of the two first circular grooves 22, and the first threaded rod 35 is threadedly rotatably installed on the inner side wall of the first threaded groove 34. Each inclined groove 32 is inclined. A measuring scale 36 is fixedly installed at the side end of the movable plate 3. The user can adjust the distance between the heat dissipation fins 5 to make it adapt to the heat dissipation requirements. The user can rotate the first threaded rod 35 forward or backward. The rotation of the first threaded rod 35 drives the sliding rod 33 to slide in the third rectangular chute 21 through the first threaded groove 34. The sliding rod 33 also drives the movable plate 3 to move. The movement of the movable plate 3 drives the two movable rods 31 to slide in the fourth rectangular chutes 23. There are several inclined inclined grooves 32 on the movable plate 3. If the movable plate 3 slides towards the side close to the heat absorption component 1, the adjusting columns 43 located in each inclined groove 32 will approach each other;

[0035] A lower connecting rod 41 is fixedly installed at the lower end of each C-shaped fixing frame 4. Two second circular grooves 42 are formed through the side end of each lower connecting rod 41. Two cross bars 24 are fixedly installed on the inner side wall of the C-shaped bottom plate 2. Each lower connecting rod 41 is slidably installed on the two cross bars 24 through the second circular grooves 42. An adjusting column 43 is fixedly installed at the lower end of each lower connecting rod 41. Each adjusting column 43 is located on the inner side wall of the inclined groove 32. Third circular grooves 45 are formed through both side ends of each C-shaped fixing frame 4. If the movable plate 3 slides away from the heat absorbing component 1, the adjusting columns 43 located in each inclined groove 32 will move away from each other. The movement of the adjusting column 43 will drive the movement of each lower connecting rod 41. The movement of the lower connecting rod 41 will drive the movement of each C-shaped fixing frame 4. The movement of each C-shaped fixing frame 4 will drive the heat dissipation fins 5 to move closer to or away from each other, thereby realizing the change of the gap between the heat dissipation fins 5;

[0036] Expansion rods 51 are fixedly installed at both side ends of each heat dissipation fin 5. Each heat dissipation fin 5 is rotatably installed on the inner side wall of the third circular groove 45. The upper end of each expansion rod 51 is fixedly installed with a second threaded rod 52.

Second threaded grooves 62 are formed through the upper end of each movable block 6. Each second threaded rod 52 is threadedly rotated and installed on the inner side wall of the second threaded groove 62. When the user uses heat dissipation, the angle of each heat dissipation fin 5 can be adjusted. The user can rotate the second threaded rod 52. When the second threaded rod 52 rotates in the second threaded groove 62, it will move up and down. The movement of the second threaded rod 52 will drive the expansion rod 51 to extend or be compressed. When the second threaded rod 52 rotates, it will drive the heat dissipation fin 5 to rotate through the expansion rod 51, thereby realizing the angle adjustment of the heat dissipation fin 5.

[0037] Working principle:

[0038] First step, when the user uses the heat dissipation fins 5 for heat dissipation, the spacing size of the heat dissipation fins 5 has an important impact on the heat dissipation effect. The smaller the spacing between the heat dissipation fins 5, usually means a larger surface area and a denser heat transfer surface, which can improve the heat transfer efficiency. However, when the spacing between the heat dissipation fins 5 is too small, it may cause blockage of the fluid channel or an increase in the flow resistance, affecting the heat transfer effect. Therefore, in actual heat dissipation use, the size of the spacing between the heat dissipation fins 5 is comprehensively considered;

[0039] In the second step, the user can adjust the spacing between the heat dissipation fins 5 to make it adapt to the heat dissipation requirements. The user can rotate the first threaded rod 35 forward or backward. When the first threaded rod 35 rotates, it drives the sliding rod 33 to slide in the third rectangular chute 21 through the first thread groove 34. The sliding rod 33 also drives the movable plate 3 to move. The movement of the movable plate 3 drives the two movable rods 31 to slide in the fourth rectangular chute 23. There are several inclined slots 32 on the movable plate 3. If the movable plate 3 slides towards the heat absorption component 1, the adjusting columns 43 located in each inclined slot 32 will approach each other. If the movable plate 3 slides away from the heat absorption component 1, the adjusting columns 43 located in each inclined slot 32 will move away from each other. The movement of the adjusting columns 43 drives the movement of each lower connecting rod 41. The movement of the lower connecting rod 41 drives the movement of each C-shaped fixing frame 4. The movement of each C-shaped fixing frame 4 drives the heat dissipation fins 5 to move closer or farther away from each other, thereby realizing the change of the gap between the heat dissipation fins 5;

[0040] By setting the heat dissipation fins 5 with adjustable spacing, the device can change the gap between the heat dissipation fins 5 according to the actual heat dissipation requirements, change the heat transfer efficiency of the heat dissipation fins 5, and change the flow resistance between the heat dissipation fins 5, so that it can adapt to various heat dissipation requirements and improve the adaptability of the device;

[0041] By setting the measuring scale 36, when each C-shaped fixing frame 4 drives the heat dissipation fins 5 to move, the user can directly observe the gap between each heat dissipation fin 5 during the movement by reading the value on the measuring scale 36, so as to facilitate the user to adjust the gap between each heat dissipation fin 5 to the appropriate position requirement and achieve a better heat dissipation effect;

[0042] By setting the cooperation of the first threaded rod 35, the movable plate 3 and the inclined slot 32, rotating the first threaded rod 35 can synchronously adjust each heat dissipation fin 5 under the cooperation of the inclined slot 32, ensuring the consistency and convenience of the adjustment. Moreover, after the adjustment, the position of the heat dissipation fins 5 can be ensured to be stable, preventing misalignment or deformation between the heat dissipation fins 5. This helps to avoid uneven thermal resistance and ensure that heat can be evenly transferred to the entire radiator surface, improving the overall heat dissipation effect;

[0043] In the third step, when the user is using heat dissipation, the user can adjust the angle of each heat dissipation fin 5. The user can rotate the second threaded rod 52. When the second threaded rod 52 rotates in the second thread groove 62, it will move up and down. The movement of the second threaded rod 52 drives the telescopic rod 51 to extend or be compressed. When the second threaded rod 52 rotates, it drives the heat dissipation fin 5 to rotate through the telescopic rod 51, thereby realizing the adjustment of the angle of the heat dissipation fin 5;

[0044] This device is provided with heat dissipation fins 5 that can be adjusted in angle, so that the heat dissipation fins 5 can be selected to dissipate heat in a right-angle state or an oblique-angle state according to actual heat dissipation requirements, thereby achieving the best heat dissipation requirements, and the adjustment is convenient, which can be achieved by rotating the second threaded rod 52, facilitating use;

[0045] This device is provided with a movable block 6 that can slide, so that the movable block 6 can slide while making gap adjustments following each heat dissipation fin 5, adapting to the position of the heat dissipation fin 5, and further ensuring that it can adapt to the heat dissipation fin 5 for angle adjustment, making the coordination between device adjustments more coordinated.

[0046] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
