Abstract: 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.
