There are multiple heat sinks hanging from the heat-conducting bracket. A heat-conducting beam is extended from the heat-conducting bracket to contact the heat dissipation device. The heat sinks are parallel to each other and perpendicular to the side panels. The advantages of the above utility model are. A Chinese patent discloses an upper isolation solid cabinet (authorization announcement number CN215579703U). The patent technology discloses an upper isolation solid cabinet, including a cabinet and a controller. The cabinet side wall is provided with a through hole, and a partition net is provided on the side of the cabinet. The partition net is provided on the outside of the through hole.

The partition net can reduce the dust and impurities from entering the instrument room. In addition, under the action of the first protective sleeve and the second protective sleeve, it can provide a certain protection effect on the inserted cable, and enhance the sealing effect of the cable penetration. Under the action of the set temperature sensor, when the temperature sensor detects that the temperature in the instrument room is higher than the set value, the flow of the internal gas is accelerated by the action of the set fan, the heat dissipation effect is improved, and the high temperature affects the working state of the instrument. This patented technology has a safe and reliable cabinet structure, making daily use more convenient, a more compact cabinet structure, good heat dissipation effect, ensuring that the components can work normally, and improving the overall cost performance and competitiveness of the product.
