Description

Technical Field

[0001] The utility model relates to the technical field of electronic component heat sinks, in particular to a retractable fin heat sink that is easy to clean. Background Art

[0002] When electronic components are working, some of the electrical energy will be converted into heat energy. If electronic components work in a high-temperature environment and there is no good heat dissipation, the efficiency of the electronic components will be reduced and the service life will be shortened. At present, the heat dissipation of electronic products mainly relies on heat sinks, among which fin heat sinks are the main form of heat sinks. Its working principle is to increase the heat dissipation area through fins and increase the heat conduction rate by setting ventilation channels.

[0003] The existing heat sink has no cleaning device and cannot be ventilated, which affects the heat dissipation efficiency and cannot meet people's requirements for fin heat sinks;

[0004] The existing patent (publication number: CN213152714U) discloses a power heat sink with stacked fins. Through a slide groove, a connecting column, a rotating shaft, a second shaft wheel and a cleaning brush, a cleaning brush is provided at the bottom of the load-bearing plate. The first shaft wheel slides inside the slide groove, thereby driving the support column to move back and forth, so that the cleaning brush cleans the fins to prevent dust accumulation on the fins from causing a decrease in the heat dissipation effect. Second shaft wheels are provided on both sides of the connecting column. The second shaft wheels can slide on the top of the slide groove as the first shaft wheel moves, thereby reducing the resistance encountered by the support column during movement, improving the practicality of the heat sink, and facilitating people's use.

[0005] In response to the above problems, existing patents have provided solutions, but they are not convenient for adjusting the fin height. In actual use, the heat dissipation area cannot be increased according to specific needs, which limits the heat dissipation efficiency of electronic components. When the electronic components are under high load operation and the heat dissipation demand is large, since the device cannot effectively adjust the fin height to increase the heat dissipation area, it is easy to cause the temperature of the electronic components to be too high, affecting the normal use of the electronic components and reducing the practicality of the device.

[0006] Therefore, a retractable fin heat sink that is easy to clean is proposed. Utility Model Content

[0007] The purpose of the present utility model is to provide a retractable fin heat sink that is easy to clean, which can solve the problem that the existing retractable fin heat sink that is easy to clean is not convenient to adjust the fin height. In actual use, the heat dissipation area cannot be increased according to specific needs, which limits the heat dissipation efficiency of electronic components. When the electronic components are under high load operation and the heat dissipation demand is large, since the device cannot effectively adjust the fin height to increase the heat dissipation area, it is easy to cause the temperature of the electronic components to be too high, affecting the normal use of the electronic components and reducing the practicality of the device.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a retractable fin heat sink that is easy to clean, comprising an electronic component, wherein both sides of the electronic component are fixedly connected to a blowing assembly, and a side of the blowing assembly away from the electronic component is fixedly connected to a plurality of adjustment assemblies, wherein the blowing assembly includes two spray plates, and the front sides of the two spray plates are fixedly connected to an air supply pipe, and the two spray plates are respectively located on both sides of the electronic component;

[0009] The adjustment assembly includes two fixed blocks, and a heat dissipation fin is movably connected between the opposite sides of the two fixed blocks, and bolts are threadedly connected to the opposite sides of the two fixed blocks. A movable block is movably connected inside the heat dissipation fin, and a heat dissipation sub-fin is fixedly connected to the side of the movable block away from the electronic component, a handle is fixedly connected to the side of the bolt away from the fixed block, and a pressing block is rotatably connected to the side of the bolt away from the handle, and the pressing block is in contact with the heat dissipation fin.

[0010] Preferably, the two air supply pipes are fixedly connected to a main pipe on one side away from the injection plate, and the main pipe is fixedly connected to a fan on one side away from the air supply pipe.

[0011] Preferably, an air suction plate is fixedly connected to a side of the fan away from the main pipe, and a filter is fixedly connected to the interior of the air suction plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The present application provides a blowing component that can spray air smoothly and quickly onto the surface of the heat sink fins. The airflow can directly remove the heat from the heat sink fins, thereby improving the heat dissipation efficiency. The continuous airflow can also prevent dust from accumulating on the heat sink, keeping the heat sink fins clean, thereby ensuring the heat dissipation effect and improving the convenience of using the device.

[0019] 2. The present application can adjust the height of the heat sink fins by setting an adjustment component.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 , this utility model provides a technical solution:

[0028] A retractable fin heat sink that is easy to clean includes an electronic component 1. A blowing assembly 2 is fixedly connected to both sides of the electronic component 1. A plurality of adjustment assemblies 3 are fixedly connected to the side of the blowing assembly 2 away from the electronic component 1. The blowing assembly 2 includes two ejection plates 201. An air delivery pipe 202 is fixedly connected to the front side of each ejection plate 201. The two ejection plates 201 are respectively located on both sides of the electronic component 1.

[0029] The adjustment assembly 3 includes two fixed blocks 301, and the heat dissipation fins 302 are movably connected between the opposite sides of the two fixed blocks 301, and the opposite sides of the two fixed blocks 301 are both threadedly connected with bolts 303, the internal movably connected with a movable block 304 of the heat dissipation fin 302, and the side of the movable block 304 away from the electronic component 1 is fixedly connected with a heat dissipation sub-fin 305, the side of the bolt 303 away from the fixed block 301 is fixedly connected with a handle 306, and the side of the bolt 303 away from the handle 306 is rotatably connected with a pressing block 307, and the pressing block 307 is in contact with the heat dissipation fin 302.

[0030] In this embodiment, by rotating the handle 306 to drive the bolt 303 to rotate, the pressing block 307 is driven to move smoothly, so that the pressing block 307 contacts the surface of the heat dissipation fin 302, which makes it easier to install and remove the heat dissipation fin 302, thereby making it easier to clean and repair it, thereby improving the convenience of using the adjustment component 3. Then, by moving the heat dissipation sub-piece 305, the moving block 304 is driven to move smoothly under the restriction of the moving groove 5, and the position of the heat dissipation sub-piece 305 can be adjusted according to actual conditions, thereby increasing the heat dissipation area, thereby achieving an increased heat dissipation effect, and improving the device. The practicality of the device is improved. Through the coordinated use of the air intake plate 205 and the filter 206, not only the air intake range is increased, but also impurities in the external air can be filtered, thus avoiding the pipe from being blocked by impurities and ensuring the normal use of the blowing component 2. At the same time, under the action of the fan 204, the air can flow smoothly into the interior of the injection plate 201, and can be smoothly sprayed on the surface of the heat dissipation fins 302, which can not only take away the heat on the heat dissipation fins 302, but also prevent dust from accumulating on the heat dissipation fins 302, thereby ensuring the heat dissipation effect of the heat dissipation fins 302 and improving the convenience of using the device.

[0031] Specifically, such as Figure 4 As shown, the two air supply pipes 202 are fixedly connected to the main pipe 203 on one side away from the injection plate 201 , and the main pipe 203 is fixedly connected to the fan 204 on one side away from the air supply pipe 202 .

[0032] Specifically, such as Figure 4 As shown, a suction plate 205 is fixedly connected to a side of the fan 204 away from the main pipe 203 , and a filter screen 206 is fixedly connected to the interior of the suction plate 205 .

[0033] Specifically, such as Figure 4 As shown, the front sides of the two injection plates 201 are each provided with a connecting hole 4 for use with the air delivery pipe 202 , and the surface of the air delivery pipe 202 is in contact with the inner wall of the connecting hole 4 .

[0034] In this embodiment: through the coordinated use of the air intake plate 205 and the filter 206, not only the air intake range is increased, but also impurities in the external air can be filtered, thus avoiding the pipeline from being clogged by impurities, ensuring the normal use of the injection assembly, and improving the convenience of using the blowing assembly 2. Moreover, through the coordinated use of the air supply pipe 202 and the connecting hole 4, the air supply pipe 202 is connected more firmly, and the air can flow smoothly into the interior of the injection plate 201 under the action of the fan 204, and can be smoothly sprayed on the surface of the heat dissipation fins 302, which can not only take away the heat on the heat dissipation fins 302, but also prevent dust from accumulating on the heat dissipation fins 302, thereby ensuring the heat dissipation effect of the heat dissipation fins 302 and improving the convenience of using the device.

[0035] Specifically, such as Figure 5 As shown, a movable groove 5 is provided inside the heat dissipation fin 302 for use with the movable block 304, and the surface of the movable block 304 is in contact with the inner wall of the movable groove 5. A movable hole 6 is provided on the side of the heat dissipation fin 302 away from the electronic component 1 for use with the heat dissipation sub-fin 305, and the movable hole 6 is connected to the movable groove 5.

[0036] Specifically, such as Figure 1 、 Figure 2 As shown, the number of the heat dissipation fins 302 is six, and the six heat dissipation fins 302 are stacked and fixedly connected to a side of the injection plate 201 away from the electronic component 1 .

[0037] In this embodiment: through the coordinated use of a plurality of heat dissipation fins 302, the contact area between the heat dissipation fins 302 and the air can be increased, and the electronic component 1 can be cooled stably. Moreover, the movable groove 5 is connected with the movable hole 6, so that the heat dissipation sub-fin 305 can drive the movable block 304 to move smoothly under the restriction of the movable hole 6. The position of the heat dissipation sub-fin 305 can be adjusted, and the heat dissipation area can be increased, thereby achieving the effect of increasing heat dissipation and improving the practicality of the device.

[0038] Specifically, such as Figure 1 、 Figure 3 As shown, a heat dissipation fan 7 is fixedly connected to the top of the electronic component 1 .

[0039] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the bottoms of the front and rear sides of the electronic component 1 are fixedly connected with connecting plates 8 , and the internal threads of the connecting plates 8 are connected with screws 9 .

[0040] In this embodiment: by using the connecting plate 8 in conjunction with the screws 9, the screws 9 penetrate the connecting plate 8 and connect to other components, so that the electronic component 1 is connected more firmly, and the stability of the device is improved. Then, under the action of the cooling fan 7, the air flow around the electronic component 1 can be accelerated, the air convection cooling effect is enhanced, and the heat dissipation effect of the device is improved.

[0041] Working principle: When the electronic component 1 is to be cooled, the bolt 303 is first rotated by turning the handle 306, which drives the pressing block 307 to move smoothly, so that the pressing block 307 contacts the surface of the heat dissipation fin 302, which makes it easier to install and remove the heat dissipation fin 302, thereby making it easier to clean and repair it. Then, by moving the heat dissipation sub-piece 305, the moving block 304 is driven to move smoothly under the restriction of the moving groove 5. The position of the heat dissipation sub-piece 305 can be adjusted according to actual conditions, thereby increasing the heat dissipation area and achieving the effect of increasing heat dissipation. Then, under the action of the heat dissipation fan 7, the air flow around the electronic component 1 can be accelerated, thereby enhancing the air convection heat dissipation effect. The use of the filter 206 and the air filter 206 not only increases the air intake range, but also filters impurities in the outside air, preventing the pipe from being blocked by impurities, and ensuring the normal use of the injection assembly. At the same time, under the action of the fan 204, the air can flow smoothly into the interior of the injection plate 201 and can be smoothly injected onto the surface of the heat dissipation fins 302, which can not only take away the heat on the heat dissipation fins 302 but also prevent dust from accumulating on the heat dissipation fins 302, thereby ensuring the heat dissipation effect of the heat dissipation fins 302. Then, by using the connecting plate 8 and the screws 9 together, the screws 9 pass through the connecting plate 8 and connect to other components, making the connection of the electronic component 1 more secure, thereby ensuring the stability of the electronic component 1.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
