The invention provides a refrigerant device, comprising semiconductor refrigerant component, which comprises hot end and coo end. On the said hot end heat radiator is set and said heat radiator comprises fluid storage box bonded with the hot end of semiconductor refrigerant component. Said fluid storage box is connected with heat radiator and cooling medium is filled between them. The partial wall, which is jointed with the hot end, is concave towards to the inner of fluid storage box and said fluid storage box is partially trapezoid. The small end of trapezoid part of said fluid storage box is jointed with the hot end of semiconductor refrigerant component and the end relative to the small end is concave towards to inner of fluid storage box. Box part, extruding to fluid storage box, is set back-up of fluid storage box. Said heat radiator is multiple and is connected with said fluid storage box separately. There is rational structure for gravitational thermal pipe radiator, high heat radiator efficiency for radiator, high refrigerant efficiency for refrigerant device.
Description
technical field [0001] The invention relates to a refrigeration device, in particular to a refrigeration device provided with a gravity heat pipe type radiator. Background technique [0002] Semiconductor refrigeration technology has the characteristics of small size, no pollution, no noise, and simple structure, so it can be applied to many occasions. The principle of semiconductor refrigeration technology is to generate heat absorption and heat release through the potential energy changes of electrons and holes in the energized circuit. The semiconductor refrigeration components generate cold ends and hot ends, and then realize the functions of cooling and heating. When the semiconductor refrigeration element is in thermal balance, to improve the cooling capacity of the cooling end, the main link is to improve the heat dissipation efficiency of the hot end, reduce the heat accumulation at the hot end, and minimize the temperature difference between the two ends to obtain m...
