Thermoelectric heat pipe combined clothes dryer

Abstract

The invention relates to a thermoelectric heat pipe combined clothes dryer which comprises a thermoelectric refrigerator, a precooling heat exchanger, a reheating heat exchanger, a draught fan and a clothes drying cylinder. The thermoelectric refrigerator comprises a thermoelectric refrigerator cold end and a thermoelectric refrigerator hot end. Thermoelectric refrigerator cold end heat absorptionpieces are arranged at the thermoelectric refrigerator cold end, thermoelectric refrigerator hot end cooling fins are arranged at the thermoelectric refrigerator hot end. A refrigerant channel of theprecooling heat exchanger and a refrigerant channel of the reheating heat exchanger form a refrigerant internal circulation loop heat pipe through a refrigerant connecting pipe. An air channel of thereheating heat exchanger, air channels of the thermoelectric refrigerator hot end cooling fins, the draught fan, the clothes drying cylinder, an air channel of the precooling heat exchanger and air channels of the thermoelectric refrigerator cold end heat absorption pieces are connected through air ducts end to end to form an air circulating circuit. Compared with the prior art, the clothes dryeris free of noise, vibration and abrasion during operating, the size of the clothes dryer is reduced, unnecessary energy loss is reduced, and meanwhile the clothes drying time is shortened.

Description

technical field [0001] The invention relates to a clothes dryer, in particular to a thermoelectric heat pipe composite clothes dryer using a thermoelectric refrigerator and a loop heat pipe. Background technique [0002] Thermoelectric refrigeration, also known as semiconductor refrigeration, is the application of thermoelectric effect (mainly Peltier effect) in refrigeration technology. The Peltier effect refers to the connection of a P-type semiconductor element and an N-type semiconductor element into a thermocouple. When the current direction flows from the hole semiconductor to the electronic semiconductor (P→N), the temperature at the joint rises and releases Heat (hot end); on the contrary (N→P), the temperature at the joint decreases and absorbs heat from the outside (cold end). A thermoelectric refrigerator is an electrical appliance that does not use refrigerant, has no moving parts, is suitable for miniaturization, works with direct current, and is easy to contro...

Problems solved by technology

[0006] However, there are still problems in the existing heat pump dryer technology: (1) there are moving parts in the working process of the compressor, which will generate large noise and vibration, which will affect the normal living environment of the user; (2) due to the relatively large volume of the heat pump device (3) In order to make the dehumidification effect better, the evaporating temperature is generally low, and the air is first cooled and dehumidified by the evaporator, and then heated by the condenser.
