2results about How to "Realize the ventilation function" patented technology

This invention relates to the field of 2G / 3G / 4G / 5G base station air conditioning technology, and more particularly to a single-cabinet intelligent air conditioner for base stations. The single-cabinet intelligent air conditioner includes a refrigerant subsystem, ventilation components, electrical control components, and a metal cabinet. In the refrigerant subsystem, the exhaust port of the electric compressor is connected to the inlet end of the compressor exhaust pipe. The outlet end of the compressor exhaust pipe is connected to the inlet end of the condenser assembly. The outlet end of the condenser assembly is connected to the inlet end of the evaporation pipe. The outlet end of the evaporation pipe is connected to the inlet end of the expansion valve. The outlet end of the expansion valve is connected to the inlet end of the evaporator core. The outlet end of the evaporator core is connected to the inlet end of the compressor suction pipe. This invention, by setting up a refrigerant subsystem, ventilation components, electrical control components, and a metal cabinet, achieves the function of cooling or ventilating the base station cabinet, thereby reducing the air temperature inside the base station cabinet, cooling the hot air inside the base station cabinet, and ensuring that the communication or other electrical components inside the base station cabinet are at a suitable operating temperature.

This disclosure relates to the technical field of cable trays. One embodiment of this disclosure provides a cable tray that is easy to fix, comprising: a tray body and a fixing frame. The fixing frame is disposed on the top of the tray body, a hanging assembly is disposed between the fixing frame and the tray body, a sealing and venting assembly is disposed on the tray body, and connecting assemblies are disposed at both ends of the tray body. The hanging assembly includes a sleeve block, which is fixed inside the bottom surface of the tray body. A hanging rod is inserted into the sleeve block, and a fixing nut is screwed to the lower end of the hanging rod. A connecting frame is disposed at the upper end of the hanging rod, and a pair of hooks are rotatably connected to the connecting frame through a pin. This technical solution solves the technical problems in the prior art where it is inconvenient to install the cable tray during use, leading to reduced work efficiency, and the existing devices cannot dissipate heat from the cables.
