Abstract

A cabinet is provided. The cabinet includes a housing, a heat generation device and a heat exchanger that are located in the housing and arranged along a first direction. The heat generation device has a device cavity, and the heat exchanger has a heat exchanger cavity. Along a second direction, an air-in cavity and an air-out cavity are respectively provided between two ends of the heat generation device and the housing. Along a third direction, a first cavity and a second cavity are respectively provided between two ends of the heat generation device and the housing. A third cavity and a fourth cavity are respectively provided between two ends of the heat exchanger and the housing. Airflow can flow through the device cavity, the air-out cavity, the first cavity, the third cavity, the heat exchanger cavity, and the fourth cavity, and enter the air-in cavity from the fourth cavity.
