Description

Technical Field

[0001] The utility model relates to the field of chassis structures, in particular to a plug-in box. Background Art

[0002] As a standard universal chassis, the plug-in box is widely used in power, communication, server and other facilities. Multiple slots can be set in the plug-in box, and multiple functional daughter boards can be inserted to achieve the desired functions.

[0003] At present, air cooling is usually used to dissipate heat in the plug-in box to absorb and discharge the heat generated by the functional sub-boards in the plug-in box. The air cooling component is usually arranged at the top of the plug-in box, and the air flow and the functional sub-board are heat exchanged by diversion. However, its spatial layout is unreasonable. After the heat exchange, the air flow is concentrated toward the air cooling component at the top of the plug-in box. The functional sub-boards located in the peripheral area of the plug-in box are more likely to generate heat than the functional sub-boards located in the middle facing the air cooling component, which is easy to affect the performance of the expected functions of the functional sub-boards. The heat dissipation effect inside the plug-in box is poor, which is not conducive to the implementation of temperature control. Utility Model Content
