Description

Door-heat exchanger integrated multilayer door and equipment with multilayer door
Technical Field
The invention relates to the technical field of operation environment adjustment of electric power and communication equipment, in particular to a door-heat exchanger integrated multilayer door with higher sealing performance and capable of realizing a heat exchange function and a cabinet or prefabricated cabin with the multilayer door.
Background
A heat exchanger is a common thermal management device and can be used for heat exchange and transfer. In the industries of electric power, communication and the like, a large number of devices are protected by cabinets or prefabricated cabins and suitable operating environments are provided, and with the development of electric power construction, the heat exchanger is widely applied to electric power cabinets or boxes needing heat dissipation, and has the advantages of isolation of internal air from external air and good sealing property. However, the existing heat exchange application mode is basically to install the equipment on the cabinet door. In the outdoor environment of a windy and sandy area or the environment with large indoor dust, a plurality of electric cabinets adopt a double-layer door structure, at the moment, the heat exchanger is structurally a complete fixed component and is positioned at the junction between the inside and the outside of the cabinet or a prefabricated cabin, and the double-layer door is completely sealed, so the heat exchanger cannot be arranged on the door. If the solar heat collector is arranged at the top of the cabinet, the requirement on the strength of the top is increased, the height of the cabinet is increased more, the solar radiation on the top is strong, and the heat exchange efficiency is lower. If the heat exchanger is arranged on the side surface of the cabinet, the heat exchanger is deviated to one side of the equipment, so that uniform heat dissipation is difficult to realize, and the center of gravity of the cabinet is offset, so that the difficulty is increased for manufacturing, installing and operating the cabinet. In practical engineering, the top or side mounting mode has no implementation significance and value.
In addition, in many prefabricated cabin integrated electrical equipment, due to the high density of equipment inside the cabin, it is also necessary to mount a heat exchanger on the cabin door. When the prefabricated cabin adopts a double-layer door structure, the heat exchanger is also required to be arranged on the cabin wall or the cabin top. If the density of equipment in the cabin is high, the cabin wall may not have enough space for installing the heat exchanger, and if installed on the roof, the total height of the cabin is increased, which affects kilometer transportation. Therefore, in actual engineering, it is sometimes difficult to install.
