Semiconductor dehumidifying and heating device

Abstract

The invention discloses a semiconductor dehumidifying and heating device which comprises a semiconductor refrigerating sheet, a cold end heat radiator, a hot end heater and a heat insulation part, wherein the cold end heat radiator comprises a first fixing plate and a plurality of first fins; the first fixing plate is fixedly connected to the cold end of the semiconductor refrigerating sheet; thefirst fins are perpendicularly mounted on the surface of the first fixing plate, are arranged in a spacing manner, and extend along the wind direction in the cold end heat radiator; the hot end heatercomprises a second fixing plate and a plurality of second fins; the second fixing plate is fixedly connected to the hot end of the semiconductor refrigerating sheet; and the second fins are perpendicularly mounted on the surface of the second fixing plate, are arranged in a spacing manner, and extend along the wind direction in the hot end heat radiator. According to the semiconductor dehumidifying and heating device, the dehumidifying effect is achieved through the cold end heat radiator; meanwhile, air is heated through the hot end heater; and accordingly, the too low air temperature causedby the dehumidifying operation can be prevented.

Description

technical field [0001] The invention relates to a gas processing device, in particular to a semiconductor dehumidification heater. Background technique [0002] At present, it is necessary to maintain a suitable temperature and humidity in daily life, even in electrical appliances, experimental instruments, and storage of articles. Among them, the control of temperature and humidity by instruments needs to be more precise. Too high or too low temperature and humidity will seriously affect the power supply. The service life of the electrical components in the cabinet and the overall operation stability of the cabinet must rely on the cabinet heater and the dehumidifier in the cabinet to accurately control the environment of the cabinet. The dehumidification equipment on the market at this stage mainly adopts the cooling method of mechanical air compressor. However, such equipment has large volume, high energy consumption, and high price, and the refrigerant will destroy the ...

Problems solved by technology

However, such equipment has large volume, high energy consumption, and high price, and the refrigerant will destroy the ozone layer and cause environmental pollution.

In addition, liquid absorbents, solid adsorbents, etc. are used to dehumidify chemically, but this type of dehumidification is usually used for one-time use, which is likely to cause waste of resources and exhaust chemicals. , impact on the environment
