Abstract: The present application discloses a machine cabinet. In one embodiment, the machine cabinet comprises a housing, and an inner chamber, a liquid working medium accommodating area, a heat exchanger and a delivery passage disposed in the housing, wherein the inner chamber is in a vacuum state and configured to accommodate electronic devices to be cooled; the liquid working medium accommodating area is configured to accommodate a liquid working medium, the liquid working medium is converted into a gas working medium to enter the heat exchanger after cooling the electronic devices to be cooled; the heat exchanger is configured to liquefy the gas working medium into a liquid working medium and guide the liquid working medium obtained by liquefying the gas working medium into the delivery passage; and the delivery passage is connected with the heat exchanger and the liquid working medium accommodating area and is configured to guide the liquid working medium obtained by liquefying the gas working medium into the liquid working medium accommodating area. The embodiment eliminates the influence of the humidity, cleanness and the like to the electronic devices due to the air circulation, and thus lengthens the service life of the electronic devices.

Abstract: The present disclosure provides a heat-dissipating system and method of a whole cabinet server system. The system comprises: a whole cabinet server system, a water-cooling plate, a water-cooling coil pipe and a fan; the water-cooling plate is disposed on each designated heat-generating element in each server of the whole cabinet server system; the water-cooling plate is configured to use low-temperature water therein to take away heat generated by the designated heat-generating element; the fan is configured to produce low-temperature air stream which flows through the whole cabinet server system and the water-cooling coil pipe in turn; the water-cooling coil pipe is configured to cool air stream that have absorbed the heat of the whole cabinet server system as low-temperature air stream. The solutions of the present disclosure can be applied to improve the heat-dissipating efficiency and reduce the costs of implementation.
