| abstract |
The invention discloses a semiconductor refrigeration and dehumidification device, which comprises a shell, wherein a cold cavity and a hot cavity which are separated by a semiconductor refrigeration sheet are arranged in the shell, a hot cavity air inlet communicated with the hot cavity, an air outlet communicated with the hot cavity and a cold cavity air inlet communicated with the cold cavity are arranged on the shell in a penetrating manner, a cold end heat absorption fin fixed on the semiconductor refrigeration sheet is arranged in the cold cavity, a hot end heat release fin fixed on the semiconductor refrigeration sheet is arranged in the hot cavity, an air blowing fan is arranged in the hot cavity, a cold and hot cavity communication hole communicated with the cold cavity and the hot cavity is arranged on the semiconductor refrigeration sheet, a control valve used for opening or sealing the cold and hot cavity communication hole is arranged on the cold and hot cavity communication hole, and the control valve. Through the setting of control flap and cold and hot chamber intercommunicating pore, cold chamber and hot chamber intercommunication can realize the dehumidification, and usable gaseous circulation is only in order effectively to heat in the hot chamber after cold chamber cuts off with hot chamber, makes semiconductor refrigeration dehydrating unit can switch between dehumidification and heating two kinds of functions. |
