Description

TECHNICAL FIELD

[0001] The utility model relates to the field of conductive sponge, especially relates to a heat dissipation conductive sponge. BACKGROUND

[0002] Conductive sponge is a medium material produced by high polymer composite foaming technology, which has a series of unique properties and applications. Conductive sponge has uniform foaming pore size, softness and elasticity, and no desquamation. Its conductive performance is uniformly distributed, which can protect the device pin and has corrosion resistance, and is an ideal medium material for long-term storage of devices. In addition, the conductive sponge has a long conductive effective period and is not affected by temperature and humidity, and the surface resistance value can be customized according to actual use. The base material of the conductive sponge usually uses a polymer with good elasticity and flexibility, such as polyurethane sponge. The conductive filler is the key ingredient to give the sponge conductivity, and the commonly used conductive fillers include carbon-based materials (such as carbon black, carbon nanotubes, graphene, etc.) and metal-based materials (such as silver, copper, etc.). These materials need to be uniformly dispersed in the matrix to ensure the conductivity of the sponge. The preparation methods include soaking method, spraying method, in-situ growth method and mixing method, etc.

[0003] In actual application, the design of side wall heat dissipation may cause the conduction path of heat in the sponge to be longer, increasing the resistance of heat transfer. Because the sponge material itself has a certain heat insulation performance, the conduction speed of heat in the sponge is relatively slow, so the design of side wall heat dissipation will further exacerbate the low heat dissipation efficiency.

[0004] The design of side wall heat dissipation may limit the effective use of heat dissipation area. The heat dissipation channel is opened in the side wall, which means that the heat dissipation area is relatively small and cannot fully dissipate heat. This will cause the heat to accumulate in the sponge, which will affect the overall heat dissipation effect of the equipment. The conductive sponge may also deform under high temperature environment, further affecting the heat dissipation efficiency. The deformed sponge may cause the heat dissipation channel to be blocked or deformed, making heat transfer more difficult. UTILITY MODEL CONTENTS

[0005] The main purpose of the utility model is to provide a heat dissipation conductive sponge, which can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the technical scheme adopted by the utility model is:

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, purposes and effects achieved by the utility model easy to understand, the following further describes the utility model in combination with specific implementation manners.

[0026] As Figure 1 - Figure 5 shown, a heat dissipation conductive sponge mainly includes a sponge main body 1. A series of structural components are arranged in order from the upper end to the lower end of the sponge column body 1, including a first anti-static sleeve 15, a first heat-conducting silica gel 16, a conductive sponge body 17, a second heat-conducting silica gel 18, and a second anti-static sleeve 19. The orderly arrangement of these components provides excellent heat dissipation performance for the heat dissipation conductive sponge.

[0027] To further enhance the heat dissipation effect, the surface of the sponge body 1 is carefully designed with multiple vertical holes 12, horizontal holes 13 and longitudinal waist holes 14. These holes not only communicate with each other, but also form a heat dissipation channel for the conductive sponge. This design enables the conductive sponge to effectively dissipate heat, ensuring temperature control during device operation.

[0028] The cross section of the longitudinal waist hole 14 is designed as an ellipse, which not only increases the heat dissipation area, but also makes the longitudinal waist hole 14, vertical hole 12 and horizontal hole 13 perpendicular to each other. This perpendicular intersection design further optimizes the heat dissipation path and improves the heat dissipation efficiency.

[0029] The heat dissipation mechanism 2 includes a telescopic heat conduction pipe 21 and an insertion hole 22. The telescopic heat conduction pipe 21 is inserted into the channel of the longitudinal waist hole 14. The side wall of the telescopic heat conduction pipe 21 is provided with multiple insertion holes 22, which are equally distributed on the telescopic heat conduction pipe 21 and correspond to the vertical holes 12. This design enables the telescopic heat conduction pipe 21 to perfectly match the heat dissipation channel of the sponge column 1, further enhancing the heat dissipation effect.

[0030] To ensure the uniformity of the heat dissipation effect, multiple vertical holes 12, horizontal holes 13 and longitudinal waist holes 14 are equally distributed on the surface of the sponge body 1. The diameters of the vertical holes 12 and the horizontal holes 13 are the same, and the diameter of the horizontal holes 13 is consistent with the width of the longitudinal waist hole 14. This consistency design ensures the uniformity of the heat dissipation channel, making the heat dissipation effect of the entire sponge body more balanced.

[0031] The telescopic heat conduction pipe 21 is also ingeniously designed, which is divided into large diameter heat conduction hose and small diameter heat conduction hose, and the two kinds of heat conduction hose are staggered. The large diameter heat conduction hose and the small diameter heat conduction hose are connected to the sponge column 1 by adhesive, and the inside of the telescopic heat conduction pipe 21 forms a heat conduction channel. This design not only increases the heat conduction area, but also improves the heat conduction efficiency.

[0032] To further enhance the heat dissipation capacity, the end of the telescopic heat conduction pipe 21 in the same row is provided with a heat dissipation fin 3. The heat dissipation fin 3 is connected with the telescopic heat conduction pipe 21 by adhesive, ensuring the stability of the structure. The heat dissipation fin 3 is composed of a heat conduction soft strip and a heat dissipation block, and multiple heat dissipation blocks are equally distributed on the heat conduction soft strip. This design maximizes the heat dissipation area, effectively improving the heat dissipation efficiency.

[0033] To ensure the smooth passage of the heat dissipation channel, a through hole 4 is provided on the heat dissipation fin 3, which is in communication with the heat conduction channel of the telescopic heat conduction pipe 21. In addition, the width of the heat dissipation fin 3 is consistent with the width of the sponge main body 1. Such design not only ensures the perfect fit of the heat dissipation fin 3 and the sponge main body 1, but also maximizes the heat dissipation area, thereby further improving the heat dissipation effect.

[0034] Use process: Place the heat dissipation conductive sponge above or around the electronic equipment or components that need to be cooled. Ensure that the surface of the heat dissipation conductive sponge is in good contact with the equipment to effectively conduct heat. If the equipment has specific cooling requirements, adjust the position of the heat dissipation conductive sponge to ensure that the heat dissipation holes are aligned with the heat source of the equipment. If the telescopic heat conduction pipe 21 is used, ensure that its insertion hole 22 is aligned with the heat dissipation channel of the sponge column 1 to enhance the heat dissipation effect. Install the heat dissipation fin 3 at the end of the same row of telescopic heat conduction pipes 21 to ensure that the heat dissipation fin 3 is in communication with the heat conduction channel of the heat conduction pipe. Ensure that the through hole 4 on the heat dissipation fin 3 is in communication with the heat conduction channel of the heat conduction pipe to ensure the smooth passage of the heat dissipation channel. During equipment operation, the heat dissipation conductive sponge will conduct heat from the equipment to the heat dissipation fin 3 through its internal heat conduction channel, thereby achieving heat dissipation.

[0035] The heat generated during equipment operation is first conducted to the surface of the heat dissipation conductive sponge. The heat is conducted through the heat dissipation channels of the vertical holes 12, horizontal holes 13 and longitudinal waist holes 14 of the sponge main body 1. The heat flows in the heat conduction channel inside the sponge main body 1, and due to the interconnectivity of the holes, the heat distribution is more uniform. The heat is further conducted to the inside of the telescopic heat conduction pipe 21 through the insertion hole 22 of the telescopic heat conduction pipe 21. The heat conduction channel inside the telescopic heat conduction pipe 21 conducts heat from the large-diameter heat conduction hose to the small-diameter heat conduction hose, improving the heat conduction area and efficiency. The heat is finally conducted to the heat dissipation fin 3, and the multiple heat dissipation blocks on the heat dissipation fin 3 dissipate heat to the surrounding environment. The through hole 4 on the heat dissipation fin 3 ensures that heat can be smoothly transferred from the heat conduction pipe to the fin, further improving the heat dissipation efficiency. Throughout the process, the heat conduction channel design of the heat dissipation conductive sponge optimizes the heat dissipation path, improves the heat dissipation efficiency, and ensures that the temperature of the equipment during operation is controlled within a safe range.
