CONDENSATION THERMOELECTRIC CABINET Russian patent published in 2014 - IPC G12B15/04 H05K7/20 G06F1/20 H02B1/56 

FIELD: machine building.

SUBSTANCE: in a device consisting of a tightly packed sealed housing, two and more injectors serving for injection of a mixture to an internal cavity of the cabinet; a highly heat-conducting plate with an installed heat-emitting equipment; a thermoelectric unit; a pin fin heat sink; a fan unit; a control unit (CU); a condensate flowdown chute; a pump serving for supply of condensate to injectors; a temperature sensor; a protective casing, it is proposed to use an evaporation and condensation cooling principle. The temperature sensor supplies a signal to CU that includes a pump for liquid supply to injectors located on the cabinet ceiling. The mixture is injected to the internal cavity of the cabinet and deposited on heat-emitting elements; its evaporation process takes place, therefore, cooling of heat-emitting elements is achieved. When vapours of the mixture go upwards, they are condensed on the ceiling (upper part of the cabinet) that is technically inclined to the rear part of the cabinet for directed condensate flowdown onto a special chute located throughout the length of the rear wall. Then it enters CU, in which the pump is installed. The mixture is supplied again to the injections through liquid channels under action of the pump. In order to amplify condensation properties of the evaporated liquid, the thermoelectric units are used, the cold junctions of which are in close contact with the upper cover of the cabinet, and the installed pin fin heat sink that is in the same close contact with the junctions of the thermoelectric units, but is on the hot side, performs heat removal. The fan unit consisting of four fans is controlled by the control unit (CU) that provides the possibility of their paired actuation for the purpose of electric energy saving.

EFFECT: preventing failure of an expensive equipment by maintaining optimum temperature.
