Description

Technical Field

[0001] This utility model relates to the field of flexible heat sink technology, specifically a flexible heat sink structure. Background Technology

[0002] Flexible heat sinks are heat dissipation materials with good flexibility, capable of adapting to various complex shapes and surfaces, and effectively conducting heat away from the heat source. Common types include thermally conductive silicone pads, thermally conductive graphite sheets, flexible metal heat pipes, and thin metal heat dissipation films.

[0003] According to Chinese Utility Model Publication No. CN222485133U, a flexible heat sink structure is disclosed, including a heat sink. A magnetic surface is provided on the lower surface of the heat sink. Two limiting circular blocks are provided on the upper side of the heat sink. Connecting plates are installed on the outer sides of the two limiting circular blocks. Connecting holes corresponding to the limiting circular blocks are opened on the wall of the connecting plates. Adhesive pads are provided on the lower sides of both connecting plates. Limiting holes are provided between the connecting plates and the adhesive pads. A limiting ring that engages with the limiting circular blocks is installed on the upper side of the connecting plates. The magnetic surface at the bottom of the heat sink allows for easy fixation of its installation position. The cooperation of the limiting circular blocks, connecting plates, connecting holes, and adhesive pads enhances the limiting effect of the heat sink and improves its positional stability. This reduces the likelihood of accidental drop during use and maintains good heat dissipation.

[0004] The aforementioned method utilizes threads to connect flexible heat sinks. When multiple heat sinks need to be connected, multiple threaded limiting rings need to be screwed on in sequence, which is cumbersome and can easily cause hand fatigue for the user. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a flexible heat sink structure that is easy to connect, solving the problem that the connection between flexible heat sinks using a threaded structure in related technologies is cumbersome and can easily cause hand fatigue for users.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a flexible heat sink structure, comprising a main body component, wherein the main body component includes:

[0009] A heat sink with a connecting plate mounted on it;

[0010] A connection assembly is provided between the heat sink and the connecting plate, the connection assembly including:

[0011] A cavity is formed in the connecting plate;

[0012] One end of the spring is fixedly connected to the inner wall of the cavity;

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, the present invention provides a flexible heat sink structure, which has the following advantages:

[0024] This flexible heat sink offers the advantage of easy connection. The limiting rod at the bottom of the heat sink is directly inserted into the cavity. When the inclined surface at the bottom of the limiting rod contacts the crossbar, it pushes the crossbar towards the spring, compressing the spring and allowing the crossbar to continue downwards. When the groove on the limiting rod moves to the same horizontal line as the crossbar, the deformed spring pushes the crossbar into the groove. The crossbar then limits the limiting rod, thus connecting the heat sink to the connecting plate. Another heat sink can be installed on the connecting plate in the same way; simply insert it to connect the heat sinks. This method is convenient and quick. It solves the problem of related technologies using threaded structures to connect flexible heat sinks, which are cumbersome and can easily cause hand fatigue for users. Attached Figure Description

[0034] 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.

[0035] Example 1

[0036] See Figure 1-5A flexible heat sink structure includes a main component 1, which includes a heat sink 11 with a connecting plate 12 disposed thereon; a connecting component 2 is disposed on the heat sink 11 and the connecting plate 12, the connecting component 2 including: a cavity 21 formed on the connecting plate 12; a spring 22, one end of which is fixedly connected to the inner wall of the cavity 21; a crossbar 23 fixedly connected to the other end of the spring 22; a connecting rod 24 symmetrically and fixedly connected to the side of the crossbar 23 away from the spring 22, the end of the connecting rod 24 away from the crossbar 23 penetrating and extending to the outside of the connecting plate 12; a pressure plate 25 fixedly connected to the end of the connecting rod 24 located outside the connecting plate 12; and a limiting rod 26 fixedly connected to the bottom of the heat sink 11. Multiple sets of the connecting component 2 are symmetrically arranged, and at least two sets are provided. The inner wall of the cavity 21 is symmetrically provided with sliding grooves 231, and both ends of the crossbar 23 extend and slide within the sliding grooves 231.

[0037] When a user needs to connect heat sink 11 to adapt to different heat dissipation scenarios, the user directly inserts the limiting rod 26 at the bottom of the heat sink 11 into the cavity 21. When the inclined surface at the bottom of the limiting rod 26 contacts the horizontal bar 23, the horizontal bar 23 is pushed towards the side closer to the spring 22. The spring 22 is compressed, making it easier for the horizontal bar 23 to continue to go deeper. When the groove on the limiting rod 26 moves to the same horizontal line as the horizontal bar 23, the spring 22, which generates elasticity after deformation, pushes the horizontal bar 23 into the groove. The horizontal bar 23 limits the limiting rod 26, thereby realizing the connection between the heat sink 11 and the connecting plate 12. Another heat sink 11 is installed on the connecting plate 12 in the same way, and the connection between the heat sinks 11 can be realized by insertion, which is relatively convenient and quick. When it is necessary to remove the heat sink 11, the user presses the pressure plate 25 towards the connecting plate 12. The pressure plate 25 drives the connecting rod 24 into the cavity 21. The connecting rod 24 pushes the crossbar 23 out of the groove of the limiting rod 26. At this time, the heat sink 11 can be pulled upward to remove it. The multiple sets of connecting components 2 connect the heat sink 11 and the connecting plate 12 through multiple limiting rods 26, increasing the firmness of the connection of the heat sink 11. When the crossbar 23 moves under the influence of the spring 22 or the connecting rod 24, both ends of the crossbar 23 slide in the slide groove 231. The slide groove 231 guides the movement of the crossbar 23, preventing the crossbar 23 from tilting during movement, thereby increasing the stability of the crossbar 23 during movement.

[0038] The heat sink 11 is attached to the part that needs heat dissipation using thermally conductive adhesive or suitable double-sided adhesive to facilitate the heat dissipation effect of the heat sink 11.

[0039] Example 2

[0040] An auxiliary function has been added based on Embodiment 1.

[0041] See Figure 1-5 The heat sink 11 has a shape memory alloy wire 3 inside. A second spring 271 is symmetrically and fixedly connected to the bottom of the cavity 21, and a plate 27 is fixedly connected to the top of the second spring 271, with the plate 27 located below the crossbar 23. A flexible element 4 is provided in the middle of the connecting plate 12.

[0042] The shape memory alloy wire 3 is a filament-like object made of an alloy material with a shape memory effect. The shape memory effect refers to the property of a material that, after being deformed under certain conditions, can recover its original shape when external conditions change. When the ambient temperature of the heat sink 11 rises, the shape memory alloy wire 3 changes shape due to heat, for example, changing from an initial straight state to a bent or coiled state, thereby altering the structure of the main component 1 and increasing the heat dissipation area. When the temperature decreases, the shape memory alloy wire 3 returns to its original shape, and the heat sink 11 returns to its initial state. This adaptive structural change can automatically adjust according to actual heat dissipation needs, improving the heat dissipation capacity of the heat sink 11 and increasing heat dissipation efficiency, especially suitable for situations where heat dissipation needs change with ambient temperature or equipment operating conditions.

[0043] When the user inserts the limiting rod 26 into the cavity 21 to install the heat sink 11, the bottom of the limiting rod 26 pushes the plate 27 downward, and the spring 271 is in a compressed state. When the user presses the connecting rod 24, the crossbar 23 releases the limiting rod 26, the spring 271 bounces the plate 27 upward, and the plate 27 ejects the limiting rod 26 out of the cavity 21, which facilitates the improvement of the efficiency of disassembling the cavity 21.

[0044] The flexible component 4 can specifically be a silicone sheet, which possesses excellent flexibility, high-temperature resistance, corrosion resistance, and biocompatibility. Positioning the silicone sheet as the flexible component 4 in the middle of the connecting plate 12 provides a high degree of freedom of movement between the two heat sinks 11. Because the silicone sheet can deform flexibly in all directions, the two heat sinks 11 can rotate relative to each other at any angle and with varying degrees of relative displacement according to actual needs. This allows the combined shape of the heat sinks 11 to freely change in three-dimensional space, better adapting to various complex installation environments and dynamic changes during equipment operation.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
