Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation fins, and more specifically, particularly relates to a heat dissipation fin convenient for cleaning. Background Art

[0002] A heat dissipation fin, also known as a heat dissipation fin, simply called a heat sink, is classified as a "passive heat dissipation component" in the field of electronic engineering design. A metal with good thermal conductivity, light weight, and easy processing is attached to the heat generating surface to dissipate heat through a composite heat exchange mode. By arranging a plurality of heat dissipation fins, the contact surface between the heat dissipation component and the outside air can be increased, and the heat dissipation effect can be improved.

[0003] When the existing heat dissipation fins are in use, the fins are fixedly arranged on the base. After long-term use, a large amount of dust and impurities will adhere to the outside of the fins, affecting the heat dissipation efficiency of the heat dissipation fins. Therefore, it is necessary to remove these dust and impurities. Since the fins are fixedly arranged on the base and the gaps between the fins are extremely small, it is difficult and cumbersome to clean the sides of the fins. General cleaning tools (such as rags, etc.) are difficult to reach into the gaps between the fins to clean the sides of the fins, with poor flexibility and low practicality.

And when it is necessary to clean the heat dissipation fin, only need to toggle the heat dissipation fin to be cleaned to one side. After the heat dissipation fin is toggled, it can be tilted to one side, thereby increasing the space between the heat dissipation fins, facilitating the cleaning operation, being convenient and flexible to use, and having extremely strong flexibility and practicality.

[0022] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0023] As attached Figure 1 To Attachment Figure 6 As shown:

[0024] Embodiment 1: The utility model provides a heat dissipation fin that is easy to clean, including a connecting base 1, which is installed on the housing of a device that needs heat dissipation; it also includes a fin assembly 2, which includes a heat dissipation fin 201 and a positioning shaft 202. The heat dissipation fin 201 is rotatably connected to the top of the connecting base 1, the shaft body of the positioning shaft 202 is inserted into the interior of the heat dissipation fin 201, and the two ends of the positioning shaft 202 are inserted into the interior of the connecting base 1, and the axis of the positioning shaft 202 and the rotation axis of the heat dissipation fin 201 are on the same straight line.

[0025] In the disclosed embodiment, a plurality of fin assemblies 2 are provided, and the fin assemblies 2 are arranged in a straight line on the top of the connecting base 1. During use, the fin assembly 2 is in a reset state when not being moved by external force. At this time, under the action of the two middle top springs 2022, the control protrusion 2011 is located in the middle of the posture groove 2023, thereby realizing the positioning of the use state (posture) of the heat dissipating fin 201, so that the heat dissipating fin 201 can be maintained in a vertical state for use, and can stably realize the heat dissipation operation of the equipment, and is stable in use.

[0026] In the embodiment of the present disclosure, a positioning block 2021 is provided on the outside of the positioning shaft 202, and a positioning groove 101 is provided on the inside of the connecting base 1. The block body of the positioning block 2021 is designed as a regular polygon, and the positioning block 2021 is inserted into the inside of the positioning groove 101. This design enables the positioning shaft 202 to only move axially inside the connecting base 1, and is stable to use.

[0027] In the embodiment of the present disclosure, a middle-position top spring 2022 is provided inside the positioning shaft 202, and both ends of the middle-position top spring 2022 abut against the inside of the positioning shaft 202 and the inside of the connecting base 1 respectively. The number of middle-position top springs 2022 provided for each group of fin assemblies 2 is two, and the two middle-position top springs 2022 of the same group of fin assemblies 2 are symmetrically arranged on both sides of the positioning shaft 202. During use, when it is necessary to clean the heat dissipation fins 201, only the heat dissipation fins 201 to be cleaned need to be waved to one side. After the heat dissipation fins 201 are toggled, they can be tilted to one side, thereby increasing the space between the heat dissipation fins 201 and facilitating the cleaning operation of the heat dissipation fins 201. Moreover, after the heat dissipation fins 201 are toggled, the heat dissipation fins 201 in the tilting direction will also be abutted and squeezed to tilt and give way, and the device will not be stuck, and the operation is convenient.

[0028] In the embodiment of the present disclosure, a spiral attitude groove 2023 is provided on the outside of the positioning shaft 202, and a control protrusion 2011 is provided inside the heat dissipation fin 201. The control protrusion 2011 is inserted into the attitude groove 2023. When both middle-position top springs 2022 of the same group of fin assemblies 2 are not compressed, the control protrusion 2011 is located in the middle of the attitude groove 2023, and the heat dissipation fin 201 is in a vertical use state. During use, after the cleaning is completed, the heat dissipation fin 201 can automatically reset to the vertical use state. When the heat dissipation fin 201 is toggled, when the heat dissipation fin 201 rotates and tilts, the control protrusion 2011 can drive the positioning shaft 202 to move to one side through the attitude groove 2023 and compress the middle-position top spring 2022 on the corresponding side to store energy. Thus, after the heat dissipation fin 201 is cleaned later, when the heat dissipation fin 201 is released, under the action of the compressed middle-position top spring 2022, the positioning shaft 202 will automatically move back to its original position, and through the cooperation of the control protrusion 2011 and the attitude groove 2023, the heat dissipation fin 201 will be restored to the vertical state for use, and the operation is convenient and flexible.

[0029] The specific usage method and function of this embodiment:

[0030] In the present invention, the fin assembly 2 is in a reset state when not being moved by an external force. At this time, under the action of the two middle top springs 2022, the control protrusion 2011 is located in the middle of the posture groove 2023, thereby realizing the positioning of the use state (posture) of the heat dissipation fin 201, so that the heat dissipation fin 201 can be kept in a vertical state for use, and the heat dissipation operation of the equipment can be stably realized. When the heat dissipation fin 201 needs to be cleaned, it is only necessary to swing the heat dissipation fin 201 to one side. After the heat dissipation fin 201 is moved, it can be tilted to one side, thereby increasing the space between the heat dissipation fins 201, facilitating the cleaning operation of the heat dissipation fin 201, and after the heat dissipation fin 201 is moved, its tilting direction The heat dissipation fin 201 will also be resisted, squeezed and tilted to avoid it, and the device will not be stuck. After cleaning, the heat dissipation fin 201 can automatically reset and restore to the vertical use state. When the heat dissipation fin 201 is moved, the control protrusion 2011 of the heat dissipation fin 201 can drive the positioning shaft 202 to move to one side through the posture groove 2023 when the heat dissipation fin 201 is rotated and tilted, and compress the middle position top spring 2022 on the corresponding side to store energy. After the heat dissipation fin 201 is cleaned later, the heat dissipation fin 201 is released and under the action of the compressed middle position top spring 2022, the positioning shaft 202 will automatically move and reset, and the heat dissipation fin 201 is restored to the vertical state for use through the cooperation of the control protrusion 2011 and the posture groove 2023.
