Radio electronic equipment condensation cabinet // 2534508
FIELD: heating.SUBSTANCE: invention relates to systems for heat removal from computer equipment mounted inside server or mounting cabinets, and namely to a condensation cabinet. The condensation cabinet consisting of a protective casing; two and more injectors serving for spraying of a mixture into an inner cavity of the cabinet; highly heat-conducting plates with installed heat releasing equipment; thermoelectric batteries (TEB); heat bridges; a pin fin heat sink; a fan unit; a control unit (CU); a condensate flowing-down chute; a pump serving for the supply of condensate to injectors, and a temperature sensor involves an evaporation and condensation cooling principle. Liquid is injected through the injectors located on the cabinet ceiling into the inner cavity of the cabinet; after it is deposited on heat releasing elements, it is evaporated, and therefore, the heat releasing elements are cooled down. Liquid vapours are condensed on the ceiling (upper part of the cabinet) that is technically made with an inclination to a rear wall of the cabinet for directed condensate flowing-down. In order to strengthen condensation properties of the evaporated liquid, TEB having a close contact of cold junctions to the upper cover plate of the cabinet are used, and the mounted pin fin heat sink that is also in close contact to TEB junctions, but already on the hot side, performs the heat pick-up. The heat bridges are located between TEB (they alternate in a staggered order with TEB) and serve for cooling of the upper surface of the cover plate by means of the pin fin heat sink and the fan units without any activation of TEB to save electric energy. The fan unit consisting of four fans is controlled by the control unit (CU) that gives a possibility of their pair activation for the purpose of electric energy saving by blowing over a radiator. TEB is fed through CU. A condensed mixture on the upper cover plate flows down through the rear wall and penetrates onto a special chute located throughout the length of the rear wall. From there, it is supplied via the liquid channel to CU, in which a pump is installed. The mixture is supplied back to the injectors through the liquid channels under the action of the pump.EFFECT: providing efficient heat removal from the cabinet volume.1 dwg
