The heat exchange module is used in the cabinet that includes a cabinet body. The cabinet body has a first space and a second space. A temperature of the first space is higher than a temperature of the second space. The heat exchange module has a first air circulation system and a second air circulation system, and heat exchange may be performed between the first air circulation system and the second air circulation system. Both an air intake vent and an air exhaust vent of the first air circulation system are configured to be connected to the first space. An air exhaust vent of the second air circulation system is connected to an external space, and an air intake vent of the second air circulation system can be configured to be selectively connected to the external space and/or the second space.

Heat exchange module and cabinet

The heat dissipation cabinet includes a cabinet body, a cabinet door, and a baffle. The cabinet body includes a top wall and a bottom wall that are oppositely disposed, and a side wall connected between the top wall and the bottom wall. The cabinet door is installed at a position of the side wall in the cabinet body, and an air outlet passage is disposed in the cabinet body that is close to a position of the top wall. An air inlet component and an air outlet component are disposed in the cabinet door, and the air outlet component is located between the air inlet component and the top wall, and is located at one end of the air outlet passage. An electronic apparatus placement area is disposed in the cabinet body, and the baffle is disposed between the electronic apparatus placement area and the cabinet door.

Heat dissipation cabinet and communication device

A temperature control cabinet includes at least one cabinet unit. Each cabinet unit includes: a subrack, where there is a placement space for placing a device inside the subrack, and there is at least one opening at a periphery of the cabinet; and a cabinet door mounted on the subrack and configured to buckle the opening, where at least two temperature control components are disposed on the cabinet door, the temperature control components are arranged in a first direction, the first direction is a direction from the top to the bottom of the subrack, each temperature control component is provided with an air exhaust vent and an air return vent, the air return vent of each temperature control component communicates with a hot area at the top of the placement space, and the air exhaust vent of each temperature control component communicates with the placement space.

Temperature control cabinet and communications system

A heat exchanger includes a vapor collection pipe, a liquid collection pipe, and an exchange pipeline. The exchange pipeline includes a condensing section, an evaporation section, and a transition section. An upper end of the condensing section is connected to the vapor collection pipe. A lower end of the condensing section is connected to a first end of the transition section. An upper end of the evaporation section is connected to a second end of the transition section. A lower end of the evaporation section is connected to the liquid collection pipe. The evaporation section and the condensing section respectively extend in directions opposite to each other.
