When installed, a thermally conductive seat 2 is arranged on the bottom surface of the soft substrate body, and a thermally conductive top plate 3 is arranged on the top surface of the soft substrate. In actual application, the thermally conductive seat and the thermally conductive top plate are both metal material structures. In addition, a plurality of vertical through holes 4 are arranged on the soft substrate body. In order to improve the thermal conductivity and the convenience of installation, a thermally conductive protruding column 5 matching the position of the vertical through hole is arranged on the top surface of the thermally conductive seat. A heat dissipation fin 6 is integrally formed on the bottom surface of the thermally conductive seat. The thermally conductive and heat dissipation performance can be improved by matching the heat dissipation fin with the thermally conductive protruding column.
[0028] Moreover, in this embodiment, the heat-conducting top plate is provided with heat dissipation slots 7, and the bottom surface of the heat-conducting top plate is adhered with a heat-conducting silicone layer 8 for contacting the soft substrate body; the heat-conducting silicone layer can protect the electronic components, and at the same time, effective thermal conductivity can be guaranteed, and in order to facilitate disassembly and connection, the bottom surface of the heat-conducting top plate is provided with a connecting column 9 that matches the position of the heat-conducting boss; the end surfaces of the heat-conducting boss and the connecting column are inlaid with magnetic sheets 10; the heat-conducting boss and the connecting column are magnetically positioned by the magnetic sheet. During the installation process, the heat-conducting boss and the connecting column are both in the vertical through hole, and then magnetically positioned by the magnetic sheet. In this embodiment, the diameters of the heat-conducting boss and the connecting column match the inner diameter of the vertical through hole. The convenience of connection can be improved, and the thermal conductivity can also be effectively achieved.
[0029] In actual application, a protective frame 11 is snapped onto the edge of the soft substrate body; the thermally conductive seat and the thermally conductive top plate are respectively attached to the bottom and top surfaces of the protective frame. In this embodiment, the protective frame can be a silicone frame, an insulating rubber frame, or a frame made of other insulating materials, which is mainly used to protect the soft substrate body to prevent the thermally conductive seat and the thermally conductive top plate from damaging the soft substrate body or electronic components during installation.
[0030] In order to improve the heat dissipation performance, a cooling fin 12 is provided on the bottom surface of the heat-conducting seat, and the inner cavity of the cooling fin is filled with coolant; the cooling fin is attached to the surface of the heat dissipation fin and fixed by screws, so that the heat of the heat-conducting seat can be quickly dissipated to improve the heat dissipation effect.

[0032] At the same time, it is provided with a protective frame edge, which will not cause damage to the soft substrate body and the electronic components thereon when the thermal seat and the thermal top plate are connected. At the same time, the cooling plate filled with coolant can improve the thermal conductivity and heat dissipation performance of the thermal seat, which is conducive to improving the stability and reliability of use.
[0033] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
