[0001] The utility model relates to the technical field of conductive foam, in particular to a spliced ​​conductive foam which is convenient for heat dissipation. Background Art

[0002] Conductive foam refers to a flame retardant sponge wrapped with conductive cloth. After a series of treatments, it has good surface conductivity and can be easily fixed on the device to be shielded with adhesive tape. Conductive foam can be divided into ordinary conductive foam, nickel-plated copper conductive foam, gold-plated conductive foam, carbon-plated conductive foam, tin-plated conductive foam, conductive aluminum foil foam, conductive copper foil foam, all-round conductive foam, SMT conductive foam, I / O conductive foam gaskets, etc. It is widely used in electronic chassis, housings, indoor chassis, industrial equipment, laptops, mobile communication equipment, etc.

[0003] The existing conductive foam uses foam as the core, and the foam core has poor thermal conductivity. During use, the heat generated inside the conductive foam cannot be released quickly, which will cause the internal temperature of the conductive foam to rise rapidly. The high temperature will affect the use of the conductive foam and reduce the use effect of the conductive foam. At the same time, the conductive foam cannot be better spliced ​​and connected, and cannot be used in combination. Therefore, a spliced ​​conductive foam that is easy to dissipate heat is proposed to solve the above-mentioned problems. Utility Model Content

[0010] Preferably, the plug hole is adapted to the size of the conductive foam body, and the four connecting ports are adapted to the size of the plug block.

The presence of the thermal conductive filler enables the heat to be more evenly distributed and conducted inside the foam; and at the same time, through the cooperation between the ultra-thin heat pipe and the heat dissipation hole, the heat can be quickly transferred from one end to the other end, which greatly increases the diffusion and discharge speed of heat and improves the heat dissipation effect.

[0022] See also Figure 1-5 In this embodiment, a spliced ​​conductive foam that is easy to dissipate heat includes a conductive foam body 1, a connecting component 2 is fixedly installed on the outer surface of the conductive foam body 1, and a heat dissipation component 3 is installed inside the conductive foam body 1.

[0023] It should be noted that the conductive foam body 1 refers to a flame retardant sponge wrapped with a conductive cloth, which has good surface conductivity after a series of treatments and can be easily fixed on the device to be shielded with adhesive tape.

[0024] The conductive foam body 1 includes a protective layer 101 installed inside the conductive foam body 1 , a foam layer 102 is installed at the bottom of the protective layer 101 , a conductive layer 103 is installed at the bottom of the foam layer 102 , an adhesive layer 104 is installed at the bottom of the conductive layer 103 , and a wear-resistant coating 105 is installed at the bottom of the adhesive layer 104 .

[0025] Specifically, the protective layer 101 is provided mainly to provide additional protection for the conductive foam body 1 to prevent the external environment from causing damage to the internal structure; the foam layer 102 provides good buffering performance, can absorb external impact and pressure, and protect the conductive layer 103 and the overall structure inside the conductive foam body 1; the outermost wear-resistant coating 105 protects the conductive foam body 1 from mechanical wear and extends its service life.

[0026] The connecting component 2 includes a connecting piece 201 fixedly installed on the right side of the conductive foam body 1, a socket 202 is opened inside the connecting piece 201, and connecting holes 203 are opened inside the connecting piece 201 and at the four corners of the inner wall of the socket 202. Four movable grooves 204 are opened inside the left side of the conductive foam body 1, and two L-shaped fixed plates 205 are fixedly installed on the inner walls of the four movable grooves 204. L-shaped movable plates 206 are slidably installed on the outer surfaces of the two groups of L-shaped fixed plates 205, and an insert block 207 is fixedly installed between one end of each two L-shaped movable plates 206. Reset springs 208 are fixedly installed on the inner walls of the four movable grooves 204.

[0027] Specifically, by setting up the connecting component 2, the four plug blocks 207 can be pressed during splicing, and the four plug blocks 207 are respectively retracted into the interior of the movable groove 204, and then one end of the conductive foam body 1 is inserted into the socket 202, and the elastic force of the reset spring 208 is used to make the plug block 207 snap into the connecting port 203, thereby realizing the splicing of the conductive foam body 1.

[0028] The heat dissipation component 3 includes a heat-conducting layer 301 fixedly installed at the center position inside the conductive foam body 1, two ultra-thin heat pipes 302 are inserted inside the conductive foam body 1, the internal gap of the conductive foam body 1 is filled with a heat-conducting filler 303, and two heat dissipation holes 304 are provided on the outer surfaces of the top and bottom of the conductive foam body 1.

[0029] Specifically, by providing the heat dissipation component 3, the conductive foam body 1 can quickly dissipate heat, and the heat can be quickly transferred from one end to the other end, which greatly increases the diffusion and discharge speed of heat and improves the heat dissipation effect.

[0030] The thermal conductive filler 303 is made of metal particles, and one end of each two heat dissipation holes 304 is connected to the ultra-thin heat pipe 302 .

[0031] Specifically, metal particles are used as thermally conductive fillers 303, which greatly improve the thermal conductivity of the material. Metals usually have a higher thermal conductivity, so that heat can be transferred more quickly within the material. The ultra-thin heat pipe 302 uses the working fluid inside it to efficiently transfer heat during evaporation and condensation, and can quickly transfer a large amount of heat from one end to the other in a very short time, so that the conductive foam body 1 can still maintain good heat dissipation performance in a high temperature environment.

[0032] To sum up, the splicing conductive foam that is easy to dissipate heat is configured by setting a connecting component 2, pressing four plug blocks 207, and the four plug blocks 207 are respectively retracted into the interior of the movable groove 204, and then one end of the conductive foam body 1 is inserted into the socket 202, and the elastic force of the reset spring 208 is used to make the plug block 207 snap into the connecting port 203 to achieve the splicing of the conductive foam body 1. By adopting the connecting component 2, the conductive foam body 1 can be quickly spliced ​​and disassembled, simplifying the installation process.

[0033] Furthermore, by providing a heat dissipation component 3 and providing a heat-conducting layer 301 in the middle layer of the conductive foam body 1, a heat conduction channel can be formed to quickly conduct heat away from the heat source; and the heat-conducting filler 303 can improve its thermal conductivity, and can enhance the heat path inside the foam layer 102, and transfer heat more effectively. The presence of the heat-conducting filler 303 enables the heat to be more evenly distributed and conducted inside the foam; and at the same time, through the cooperation between the ultra-thin heat pipe 302 and the heat dissipation hole 304, heat can be quickly transferred from one end to the other end, which greatly increases the diffusion and discharge speed of heat and improves the heat dissipation effect.
