Description

Technical Field

[0001] This utility model belongs to the field of fiber sheet technology, and specifically relates to a heat-resistant fiber sheet with a self-contained heat dissipation structure. Background Technology

[0002] Fiber sheets are thin, sheet-like structures made from natural or synthetic fiber materials, widely used in various fields. They possess advantages such as lightweight, high strength, and corrosion resistance, and can serve as a basic component for reinforcing materials, insulation materials, or functional composite materials. Fiber sheets are also used to cover the outside of roller assemblies. The combination of roller assemblies and fiber sheets generates significant heat. However, common fiber sheet designs lack dedicated heat dissipation structures, relying solely on a simple, single heat-conducting layer in the material stacking. This results in extremely low heat dissipation efficiency. Prolonged high-temperature operation can cause the polymers or composite materials within the fiber sheet to soften, deform, or even decompose, significantly reducing its mechanical strength and physical properties. Furthermore, sustained high temperatures accelerate the aging process, making the fiber sheet more prone to cracking and delamination, thus shortening its service life.

[0003] In summary, fiber sheets with poor heat dissipation performance present some problems during use. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content

The two sets of interlaced blocks are interlaced and the fitting blocks and fitting grooves fit into each other.

[0013] In a preferred embodiment, two sets of connecting brackets are fixedly connected to the front and rear ends of the inner side of the fiber sheet assembly.

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.

[0026] Please see Figures 1 to 5 The present invention provides a technical solution: a heat-resistant fiber sheet with a self-contained heat dissipation structure, comprising: a fiber sheet assembly 100, wherein the fiber sheet assembly 100 is provided with a fiber sheet outer layer 101 for improving high temperature resistance and mechanical strength;

[0027] A heat dissipation layer is fixedly connected to one end of the outer layer 101 of the fiber sheet near the center of the fiber sheet assembly 100. Several heat dissipation cavities 103 are opened on the inner side of the heat dissipation layer for the fiber sheet assembly 100 to generate heat dissipation airflow when it is squeezed by external force.

[0028] A pneumatic seat 104 for pressing and holding is fixedly connected to the inner side of the heat dissipation cavity 103. Three sets of heat dissipation holes 102 for communicating with the outside are opened on both the front and rear sides of the fiber sheet assembly 100. A connecting hole 105 for assisting heat conduction is opened between the two sets of heat dissipation cavities 103. An external connecting hole 106 is opened at the middle position of the connecting hole 105 towards the outside of the fiber sheet assembly 100.

[0029] The fiber sheet assembly 100 is also provided with annular heat dissipation holes 107 in the circumferential direction for circulating auxiliary heat conduction, and the annular heat dissipation holes 107 are interconnected with the connecting holes 105.

[0030] The connecting hole 105 is also connected to the external connecting hole 106. The front and rear heat dissipation cavities 103 are connected to the front and rear heat dissipation holes 102 respectively. When the fiber sheet assembly 100 is in use, the outer side is subjected to pressure, which causes the air pressure seat 104 in the heat dissipation cavity 103 to expand and contract, forming airflow and creating a guide channel when connected to the outside, so that the heat generated inside is directed to the outside.

[0031] The outer layer 101 of the fiber sheet is made of a composite laminate of the outermost ceramic fiber layer 101a, the middle glass fiber layer 101b and the inner thermal insulation cotton layer 101c. Several sets of longitudinally arranged thermally conductive carbon fibers 110 are fixedly connected to one end of the heat dissipation layer near the center of the fiber sheet assembly 100.

[0032] Several sets of thermally conductive carbon fibers 110 are filled with several sets of thermally conductive particles 109 near the center of the fiber sheet assembly 100. The thermally conductive particles 109 are made of graphene material.

The inner heat-conducting layer 108 is made of a flexible heat sink and graphene material. The inner layer of the fiber sheet 116 is fixedly connected to the inner heat-conducting layer 108 near the center of the fiber sheet assembly 100. The heat-conducting particles 109 made of graphene material conduct heat to the heat-conducting carbon fiber 110, thereby improving the heat conduction effect.

[0034] Please see Figures 1-5 As the first embodiment of this utility model: First, the user wraps the fiber sheet assembly 100 around the outside of the roller group. During use, the outer surface of the fiber sheet assembly 100 is subjected to extrusion pressure, and the air pressure seat 104 in the extrusion heat dissipation cavity 103 expands and contracts to generate airflow. This airflow forms a heat conduction channel through several interconnected sets of connecting holes 105 and heat dissipation holes 102 and external connecting holes 106 connected to the outside. The heat conduction can be improved through the annular heat dissipation holes 107, increasing the heat flow in the flow channel. Second, the heat-conducting particles 109 made of graphene material conduct heat to the heat-conducting carbon fiber 110, thereby improving the heat conduction effect. The generated heat is conducted to the heat dissipation layer. The outer layer 101 of the fiber sheet, which is composite laminated with ceramic fiber layer 101a, glass fiber layer 101b and heat insulation cotton layer 101c, improves the high temperature resistance and mechanical strength, thereby improving the heat dissipation effect.

[0035] A set of connecting brackets 111 is fixedly connected to the openings on both the front and rear sides of the fiber sheet assembly 100, and a set of interlocking blocks 112 is fixedly connected to the adjacent parts of the two sets of connecting brackets 111.

[0036] The left interlacing block 112 has a fitting groove on one side near the center of the fiber sheet assembly 100, and the right interlacing block 112 has a fitting block 113 fixedly connected on one side away from the center of the fiber sheet assembly 100. The two sets of interlacing blocks 112 are interlaced and connected so that the fitting block 113 and the fitting groove fit together.

[0037] Two sets of connecting brackets 114 are fixedly connected to the front and rear ends of the inner side of the fiber sheet assembly 100. The rear side of the connecting bracket 111 and the connecting bracket 214 are vertically penetrating to form a connecting threaded hole 115. The fiber sheet assembly 100 covers the outside of the roller group. The two sets of connecting brackets 111 at the end are staggered and connected so that the connecting bracket 111 and the connecting bracket 214 are fitted into the corresponding grooves of the roller group, and the bolts are screwed into the connecting threaded hole 115 to connect and fix the fiber sheet assembly 100.

[0038] Please see Figures 1-2As a second embodiment of this utility model: Based on the first embodiment above, the user can connect the fiber sheet assembly 100 to the roller group by interleaving the two sets of connecting card seats 111 at the end, and interleaving the interleaved blocks 112 so that the fitting block 113 fits into the fitting groove, and the connecting card seat 111 and the connecting card seat 2 114 fit into the corresponding groove of the roller group, and screw the bolt into the connecting thread hole 115 to connect and fix the fiber sheet assembly 100, thereby facilitating the positioning and disassembly of the fiber sheet assembly 100.
