Abstract: This application provides a cabinet. The cabinet includes a cabinet body. A first-stage temperature control component configured to control a temperature of the cabinet body is disposed on the cabinet body, and at least one temperature control capacity expansion interface that may be used to connect a second-stage temperature control component and the cabinet body is disposed on the cabinet body, so that the second-stage temperature control component is disposed on the cabinet body in an expandable manner. The cabinet provided in this application can avoid a waste of a temperature control component, expand a heat dissipation capability of the cabinet, and resolve an existing problem that the temperature control component is wasted and the heat dissipation capability of the cabinet cannot meet an upgrade requirement due to replacement of the temperature control component when the heat dissipation capability of the cabinet is insufficient.
