Abstract

A chassis suitable for complex environments, including a box body, an evaporator arranged in the box body, and a double-layer shielding device arranged at the front end of the box body; the double-layer shielding device includes a box fixed to the box body The connected door inner sealing plate, the door panel arranged at the front end of the door inner sealing plate, and the sealing buckle mechanism arranged between the door panel and the box body; wherein, the sealing buckling mechanism includes the The U-shaped fastening groove around the front end of the box, the U-shaped sheet metal parts and the fastening lock arranged around the door panel; A sealing strip and a beryllium copper reed are arranged between the U-shaped sheet metal part and the U-shaped fastening groove. The chassis adopts multi-layer shielding design, which can meet electromagnetic shielding; high IP level, can meet the normal work in harsh environment (high temperature and high humidity); good heat dissipation effect, can effectively ensure the temperature in the chassis, and prolong the working life of the device.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a cabinet suitable for complex environments. Background technique [0002] As the chassis is used more and more frequently in the fields of electronic communication, testing, and industrial sites, the field environment of the chassis is becoming more and more complex, so the design of the chassis is also put forward higher and higher requirements. In the electromagnetic environment, electronic equipment or systems are required to meet the requirements of EMC standards, and can work normally in the expected electromagnetic environment without performance degradation or failure, which requires the chassis to meet the requirements of electromagnetic compatibility. For low-frequency magnetic fields, The requirements for the chassis are even higher; in the high and low temperature humid heat environment, it is required that the electronic equipment or system can operate for a...
