DETAILED DESCRIPTION

[0019] The first embodiment of the present application is:

[0020] See also Figure 1 , Figure 1 It is a structural schematic diagram of the present invention, including a cabinet body 101, a control main board 102 and a heat dissipation component 103, wherein the heat dissipation component 103 includes a heat absorbing plate 104, a heat dissipation column 105, an exhaust fan 106 and a dust cover 107; the heat absorbing plate 104 includes a thermally conductive silicone pad 108 and a thermally conductive plate 109, and the dust cover 107 includes a mounting frame 110 and a dust net 111. The above-mentioned scheme solves the problem that the existing display cabinets use heat dissipation holes for heat dissipation, have poor heat dissipation efficiency, and are easily affected by the use of the display cabinets. It can be understood that the above-mentioned scheme can be used in the scene where the display cabinets are working and dissipating heat.

[0021] For this specific implementation, the control main board 102 is fixedly connected to the cabinet 101 and is located inside the cabinet 101. The cabinet 101 is used to pass the installation conditions of the control main board 102 and protect the control main board 102. The control main board 102 is used to provide power for the cabinet and precision air conditioner and is used in the cold channel.

[0022] The heat absorbing plate 104 is fixedly connected to the control mainboard 102 and is located on one side of the control mainboard 102. The heat dissipating column 105 is fixedly connected to the heat absorbing plate 104 and passes through the cabinet 101. The exhaust fan 106 is arranged on one side of the cabinet 101. The dust cover 107 is detachably connected to the cabinet 101 and is located on the side of the cabinet 101 close to the exhaust fan 106. The heat dissipating component 103 is used to dissipate heat from the control mainboard 102. When the heat dissipating component 103 is used, the heat generated by the operation of the control mainboard 102 is firstly absorbed by the heat absorbing plate 104. The heat absorbing plate 104 then transfers the absorbed heat to the heat dissipating column 105. The heat dissipating column 105 then exchanges air with the air outside the cabinet 101. Heat is dissipated, thereby achieving the purpose of heat dissipation of the control mainboard 102. When the temperature sensor inside the cabinet 101 detects that the internal temperature of the cabinet 101 reaches a preset value, the control mainboard 102 controls the exhaust fan 106 to operate. The exhaust fan 106 operates to exhaust the hot air in the cabinet 101, and the external air flows into the cabinet 101 through the heat dissipation holes, thereby accelerating the air flow in the cabinet 101, and further accelerating the heat dissipation of the control mainboard 102. The heat dissipation component 103 has a faster heat dissipation speed and a better heat dissipation effect than the traditional heat dissipation hole convection heat dissipation of the traditional display cabinet, thereby avoiding the phenomenon of untimely heat dissipation of the display cabinet, and solving the problem that the existing display cabinet adopts heat dissipation holes for heat dissipation, the heat dissipation efficiency is poor, and it is easy to affect the use of the display cabinet.

[0023] Secondly, the thermally conductive silicone pad 108 is fixedly connected to the control main board 102 and is located on one side of the control main board 102. The thermally conductive plate 109 is fixedly connected to the thermally conductive silicone pad 108 and is located on the side of the thermally conductive silicone pad 108 away from the control main board 102. The thermally conductive plate 109 is used to absorb the heat generated by the control main board 102 and transfer the absorbed heat to the heat dissipation column 105 for heat exchange with the outer shell air. The thermally conductive plate 109 is made of metal material. The setting of the thermally conductive silicone pad 108 is used to increase the contact area between the thermally conductive plate 109 and the control main board 102, thereby improving the thermal conductivity effect of the thermally conductive plate 109.

[0024] At the same time, the mounting frame 110 is detachably connected to the cabinet 101 and is located on the side of the cabinet 101 close to the exhaust fan 106.

The mounting frame 110 is configured to install and fix the dustproof net 111 on one side of the exhaust fan 106. The dustproof net 111 is configured to provide dustproof protection for the control mainboard 102 in the cabinet 101 to prevent dust from entering the cabinet 101 from the exhaust fan 106 when the exhaust fan 106 is not in operation, thereby causing dust accumulation on the control mainboard 102 and accelerating aging.

[0025] When the heat dissipation component 103 is in use, the heat generated by the operation of the control mainboard 102 is first absorbed by the heat conducting plate 109, and the heat conducting plate 109 then transfers the absorbed heat to the heat dissipation column 105, and the heat dissipation column 105 then exchanges heat with the air outside the cabinet 101, thereby achieving the purpose of dissipating heat from the control mainboard 102. When the temperature sensor inside the cabinet 101 detects that the internal temperature of the cabinet 101 reaches a preset value, the control mainboard 102 controls the exhaust fan 106 to operate, and the exhaust fan 106 operates to exhaust the hot air in the cabinet 101, and the external air flows into the cabinet 101 through the heat dissipation holes.

[0029] Among them, the drying plate 202 is slidably connected to the mounting frame 110 and is located on the side of the mounting frame 110 close to the dustproof net 111. The drying box 203 is detachably connected to the cabinet 101 and is located inside the cabinet 101. The drying plate 202 is a common technology on the market and is used to dry the air entering the cabinet 101 when the exhaust fan 106 is not in use. It is inevitable that humid air will enter when the cabinet 101 is turned on and off. The setting of the drying box 203 is used to dry the air inside the cabinet 101 to avoid water vapor affecting the use of the control motherboard 102.

[0030] Secondly, the adsorption block 204 is detachably connected to the cabinet 101 and is located inside the cabinet 101. The box body 205 is fixedly connected to the adsorption block 204 and is located on the side of the adsorption block 204 away from the cabinet 101. The drying layer 206 is arranged in the box body 205. The adsorption block 204 is a magnet, which is used to adsorb and fix the box body 205 inside the cabinet 101, so that workers can remove the box body 205 to replace the drying layer 206 therein. The box body 205 has a plurality of through holes. The drying layer 206 is used to absorb moisture in the air in the cabinet 101 to prevent water vapor from affecting the use of the control main board 102. The drying layer 206 is made of quicklime.

[0031] When the moisture-proof component 201 is in use, the air entering from the exhaust fan 106 is dried by the drying plate 202 , and the air inside the cabinet 101 is dried by the drying layer 206 .
