Description

Technical Field

[0001] The utility model relates to the technical field of heat sinks, in particular to a VC copper sheet heat sink. Background Art

[0002] At present, VC copper sheet heat sinks are usually vacuum chamber heat spreaders. In the early days, mobile phone heat dissipation generally used graphite as the main material, which can be called the first generation of heat dissipation. Then copper tube liquid cooling is the second generation of heat dissipation technology, and VC heat spreader is the latest third generation of heat dissipation technology. VC liquid cooling can be regarded as an upgraded technology of copper tube liquid cooling. Although both are based on the principle of gas-liquid phase change, the difference is that heat pipes only have a "linear" effective thermal conductivity in a single direction, while VC is equivalent to an upgrade from "line to surface", which can better take away heat from all directions.

[0003] The Chinese utility model patent with publication number CN215264695U in the prior art relates to a VC heat sink used on an integrated board, comprising a VC heat sink and a heat sink, wherein the VC heat sink contacts the heat source on the integrated board to absorb heat, and the heat sink is installed on the VC heat sink to dissipate heat; the VC heat sink has multiple contact plates for contacting the heat source located at different height planes; based on the existing heat sink, a structural improvement is made, and multiple contact plates are arranged on a VC heat sink to contact the heat source located at different height planes, the VC heat sink can dissipate heat for multiple heat sources at the same time, and the heat sources at different heights can be dissipated through the same heat sink, effectively improving the heat dissipation effect and reducing material and energy consumption; the heat sink is equipped with a heat dissipation fan, and the heat dissipation effect will not be bad in the case of multiple high-power heat sources.

[0004] However, during use, this type of radiator conducts heat to planar heat sources of different heights through multiple contact plates, but the CPU central processing unit in the computer requires a relatively large heat sink, so the radiator needs to dissipate heat from multiple heat sources at the same time, which will cause the power load of the radiator and uneven heat dissipation, affecting the heat dissipation effect. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a VC copper sheet heat sink to solve the problem that the radiator in the prior art conducts heat to planar heat sources of different heights through multiple contact plates during use, but the CPU central processing unit in the computer requires a relatively large heat sink, and the radiator needs to dissipate heat from multiple heat sources at the same time, which will cause the power load of the radiator and uneven heat dissipation effect, affecting the heat dissipation effect.

[0006] The purpose and effect of a VC copper sheet heat sink in the utility model are achieved by the following specific technical means: a VC copper sheet heat sink, comprising a shell, an installation cavity and a heat sink body, the installation cavity is opened inside the shell, the heat sink body is arranged in the installation cavity, a support point is fixedly connected to the top of the shell, a bottom cover located below the installation cavity is arranged at the bottom of the shell, and a mesh is fixedly installed in the middle of the heat sink body.

[0015] 1. The mesh is arranged in a multi-layer splicing shape, and partitions are fixedly connected between the meshes. The partitions are used to support the multi-layer meshes. The mesh is X-shaped and the middle is hollowed out. After the mesh absorbs the heat, the mesh dissipates the heat into the air more evenly, so that the power of the heat dissipation body is not prone to load problems, the heat dissipation effect is uniform, and the heat dissipation effect is improved.

[0016] 2. The bottom cover is detachably arranged at the bottom of the shell, and plug rods are fixedly connected on the inner wall of the installation cavity and the side wall of the bottom cover.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] As attached Figure 1 To Attachment Figure 4 As shown: a VC copper sheet heat sink, comprising a shell 1, an installation cavity 2 and a heat sink body 3, the installation cavity 2 is opened inside the shell 1, the heat sink body 3 is clamped in the installation cavity 2, after the heat sink body 3 is installed and limited inside the installation cavity 2, the entire heat spreader is docked on the top of the shell 1, so that the heat spreader and the heat source component are in contact to absorb heat, and thermal conductive silica gel is used at the contact point between the heat spreader and the heat source component, so that the heat spreader can absorb heat better, thereby improving the heat dissipation effect of the heat source component.

[0024] Among them, a support point 101 is fixedly connected to the top of the shell 1, and the heat balancing plate and other connecting parts are connected through the support point 101, so that the shell 1 is more convenient to install the heat dissipation body 3 and the stability of the heat dissipation body 3 is improved. The support point 101 can also be used for installation and connection with fans required for heat dissipation.

[0025] It should be understood that the above-mentioned fixed connection means that there can be no relative movement between the two. There are many ways of fixed connection. Here, an integrated way can be used for fixing so that the support point 101 and the heat balancing plate and other connecting parts are connected to achieve better flatness.

[0026] A bottom cover 201 is installed at the bottom of the shell 1, and the heat dissipation body 3 is enclosed in the installation cavity 2 through the bottom cover 201 to prevent the heat dissipation body 3 from loosening and other problems, making it more convenient to disassemble and maintain the heat dissipation body 3 in the later stage, and removing the remaining ash and slag on the surface of the heat dissipation body 3 is more efficient.

[0027] A mesh 4 is fixedly installed in the middle of the heat dissipation body 3, so that after the heat spreader and the heat dissipation body 3 are connected, for a heat source on an integrated board, after the entire heat spreader contacts and absorbs heat, the heat will be transferred to the mesh 4 in the heat dissipation body 3, and after the mesh 4 absorbs the heat, a corresponding fan will be installed below or above the mesh 4, so that the fan can be started to blow away the heat absorbed above the mesh 4, and the heat absorbed by the mesh 4 can be quickly removed, the heat absorption effect of the mesh 4 is better, and the heat dissipation effect of the heat dissipation body 3 is improved. Example

[0028] As attached Figure 1 To Attachment Figure 4 As shown: the bottom cover 201 is arranged above the housing 1, and the bottom cover 201 is detachably arranged at the bottom of the housing 1, so that the bottom cover 201 can be removed from the bottom of the housing 1, making it more convenient to disassemble and maintain the heat dissipation body 3 from the housing 1.

[0029] The bottom of the bottom cover 201 is threadedly connected with a fixing screw 202 extending into the housing 1 , thereby making the bottom cover 201 more stably connected to the bottom of the housing 1 .

[0030] As attached Figure 1 To Attachment Figure 4 As shown: an insertion rod 302 is fixedly connected to the inner wall of the installation cavity 2 and the side wall of the bottom cover 201, and the insertion rod 302 is located at the upper and lower sides of the installation cavity 2. A limiting hole 301 corresponding to the insertion rod 302 is opened on the side wall of the heat dissipation body 3, and the insertion rod 302 is clamped in the limiting hole 301, so that when the heat dissipation body 3 is installed in the installation cavity 2, the positioning effect of the heat dissipation body 3 is better, and there will be no problems such as offset, thereby improving the heat dissipation effect of the heat dissipation body 3.

[0031] The limiting holes 301 are located at the edges of the heat dissipation body 3 , which improves the fixing effect while the mesh 4 in the middle of the heat dissipation body 3 is not affected, thereby improving the absorption effect of the mesh 4 on the heat source.

[0032] As attached Figure 1 To Attachment Figure 4 As shown: the mesh 4 is arranged in a multi-layer splicing shape, and partitions 401 are fixedly connected between the meshes 4. The partitions 401 are used to support the multi-layer meshes 4, thereby improving the fixing effect between the meshes 4. The multi-layer mesh 4 can absorb the heat source evenly, thereby making the mesh 4 dissipate heat more evenly.

[0033] Among them, the mesh 4 is X-shaped and hollowed out in the middle, so that after the mesh 4 absorbs the heat, the mesh 4 dissipates the heat into the air more evenly, so that the power of the heat dissipation body 3 is not prone to load problems, the heat dissipation effect is uniform, and the heat dissipation effect is improved.

[0034] Working principle: when the heat dissipation body 3 is installed in the installation cavity 2, the limiting hole 301 above the heat dissipation body 3 will be stuck in the insertion rod 302 above the installation cavity 2 for fixing, so that when the bottom cover 201 is covered on the bottom of the installation cavity 2, the insertion rod 302 above the bottom cover 201 will be stuck in the limiting hole 301 at the bottom of the heat dissipation body 3 for support, so that the stability of the heat dissipation body 3 in the installation cavity 3 is better. By installing the fixing screw 202 at the bottom of the bottom cover 201, the bottom cover 201 is fixed to the bottom of the shell 1 to enclose the heat dissipation body 3 in the installation cavity 2, and the heat balancing plate and other connecting parts are connected through the supporting point 101. After the entire heat balancing plate contacts the heat source on the integrated board and absorbs heat, the heat will be transmitted to the mesh 4 in the heat dissipation body 3 through the heat balancing plate. After the mesh 4 absorbs heat, a corresponding fan is installed below or above the mesh 4, so that the heat absorbed by the mesh 4 can be quickly removed, thereby improving the heat dissipation effect of the heat dissipation body 3.
