Description

A kind of heat pump heat pipe combined type dryer
Technical field
The present invention relates to dryer technical fields, and in particular to a kind of heat pump heat pipe combined type dryer.
Background technique
Heat pipe is a kind of novel heat transfer element, and cardinal principle is the phase condensed after the evaporation of hot end in cold end using medium Change process (utilizes the evaporation latent heat and the latent heat of condensation of liquid), conducts heat quickly, and the capacity of heat transmission is more than any known The capacity of heat transmission of metal.Loop circuit heat pipe is a kind of efficient phase change heat-transfer device, it is made of evaporator, condenser, passes through gas Liquid transfer conduit connects into circuit, transmits heat using the evaporation and condensation of working medium, can be the small temperature difference, long range the case where The lower a large amount of heat of transmitting.Loop circuit heat pipe has become the preferred heat transfer element of aviation thermal control system at present, sets in Ground Electronic Also increasingly important role is just being played in standby cooling system.
Dryer currently used in the market is mainly electrothermal dryer, it utilizes PTC heater element, passes through electric heating Mode improve air themperature, make stream of hot air through clothing surface under fan action, the water of clothing taken away by hot and humid area Point, realize the acceleration drying of clothing.Cheap because its structure is simple, electrothermal dryer accounts for exhausted most market share.But Since electrothermal dryer directly uses electric-heating-wire-heating air, a large amount of electric energy is consumed, and pass through the higher temperatures high humidity of clothing Air-flow be directly discharged into interior, hot wet soiling can be caused to interior.In order to solve the problem above of electrothermal dryer, expedite the emergence of Heat pump clothes dryer.
Heat pump clothes dryer is a kind of Novel clothes (or textile) drying equipment using heat pump techniques.In heat pump clothes dryer In system, there are heat pump cycle and two closed cycles of air circulation, two cycle through evaporator and condenser progress heat Exchange.In heat pump cycle, by compressor work, a small amount of electric energy is consumed, refrigerant circulation is driven, makes refrigerant in evaporator It is middle absorb exhaust waste heat and condensed water from drying bucket latent heat, within the condenser with higher temperature reject heat to by into Enter the air of drying bucket.In air circulation, under the promotion of blower, the damp-heat air being discharged from drying bucket is in evaporator Reduce temperature, and the moisture in condensation air;The air of the low water capacity of low temperature is heated up by condenser later, but water capacity Constant, relative humidity reduces, and air absorbs the very capable of moisture at this time;Finally, the air of high temperature low relative humidity blows over clothing Object surface, clothing carry out hot and humid area, release heat, take away moisture.Since system continually enters electric energy, to maintain circulation air Energy balance, system need to pass through setting auxiliary cooler, auxiliary condenser or supplement fresh air maintain system stablize.Heat pump clothes-drying Machine has many advantages, such as that energy consumption is low, small on indoor air quality influence, drying effect is good;Meanwhile the drying temperature of heat pump clothes dryer Lower than electrothermal dryer, the damage that air temperature is too high to clothing surface is avoided.
However, there are still a problems for existing heat pump clothes dryer technology: in order to keep effect on moisture extraction more preferable, evaporating temperature is general It is lower, and air first passes through evaporator cool-down dehumidification, is heated using condenser, and front and back is cold and hot to offset, and bringing need not The energy loss wanted.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide it is a kind of energy consumption less, drying when Between short heat pump heat pipe combined type dryer.

Present invention adds loop circuit heat pipes, reduce the unnecessary energy loss of system, realize air by loop circuit heat pipe By the pre-cooling and reheating before and after evaporator, reduces the cold and hot of front and back and offset, to further reduced the electricity of heat pump clothes dryer It can consume, shorten drying time.
The loop circuit heat pipe includes gravity drive hydrodynamic system loop circuit heat pipe or the driving loop circuit heat pipe of refrigerated medium pump.
Several closed cycles of gravity drive hydrodynamic system loop circuit heat pipe, each closed cycle include head and the tail connection and parallel A precool heat exchanger device coolant channel and a heat exchanger again coolant channel, the refrigeration of the heat exchanger again The height in agent channel is higher than the coolant channel of precool heat exchanger device, and the coolant channel of all heat exchangers again is located at same vertical On face, the coolant channel of all precool heat exchanger devices is located on same vertical plane, and the coolant channel of the evaporator is located at two Between a vertical plane.It, can be by precool heat exchanger device system since the high-temperature gas in drying cylinder initially enters precool heat exchanger device Refrigerant vapor in coolant channel ascends into again the coolant channel of heat exchanger by pipeline;The refrigerant of gasification exists It is condensed into drop in the coolant channel of heat exchanger again, is flowed back in precool heat exchanger device coolant channel by gravity, is successively followed Ring.
The driving loop circuit heat pipe of the refrigerated medium pump include a precool heat exchanger device coolant channel and one again The coolant channel of heat exchanger, the outlet of the coolant channel of the precool heat exchanger device and the coolant channel of heat exchanger again Import connection, the outlet of the coolant channel of the heat exchanger again is logical by the refrigerant of refrigerated medium pump and precool heat exchanger device The import in road connects, and the coolant channel of the evaporator is located at the coolant channel and the system of heat exchanger again of precool heat exchanger device Between coolant channel.
The precool heat exchanger device and again heat exchanger are refrigerant air heat exchangers, including finned tube exchanger, micro- logical One of road heat exchanger or plate heat exchanger.
The throttling set includes one of capillary, short tube or electric expansion valve.
Main working process of the invention are as follows: the high temperature dry air through condenser heating enters drying under fan action The air of cylinder, high temperature drying improves clothing temperature by hot and humid area, and takes away the moisture in clothing, becomes low temperature and high relative humidity sky Gas;Later, low temperature and high relative humidity air enters precool heat exchanger device, and the pre-cooling of air is realized in refrigerant heat absorption evaporation;Air after pre-cooling The further cool-down dehumidification in evaporator, becomes low temperature and low humidity air;Finally, low temperature and high relative humidity air enters heat exchanger again, system Cryogen exothermic condensation realizes the reheating of air;Air after reheating further heats in condenser, becomes high temperature drying sky Gas has stronger wettability power again.
Compared with prior art, the beneficial effects of the present invention are embodied in: loop circuit heat pipe is introduced heat pump clothes dryer by the present invention, Reduce unnecessary energy loss.It is combined by evaporator plus loop circuit heat pipe, the pre-cooling and reheating before and after Lai Shixian evaporator, from And the power consumption of heat pump clothes dryer is further decreased, while shortening drying time.
