See Fig. 1, the refrigerator with heat preservation and dryness mechanism comprises freezing and refrigeration room 7 and refrigeration mechanism.Refrigeration mechanism comprises evaporimeter 17, capillary 16, compressor 14 and condenser 15, and evaporimeter 17 is positioned at freezing and refrigeration room 7, and capillary 16, compressor 14 and condenser 15 are all positioned at the outside of freezing and refrigeration room 7.Bottom outside freezing and refrigeration room 7 is provided with moist closet 8.Moist closet 8 inner bottom part is equipped with phase-change thermal storage block 5, and phase-change thermal storage block of material is shaping phase-change material, and the research of shaping phase-change material is comparatively ripe in the field of about 40 ~ 50 DEG C in phase transition temperature, has plurality of optional scheme.The result of study of Department of Science and Technology's 11th Five-Year national science and technology supporting plan project that China Science & Technology University bears, content is that building accumulation of energy insulation material and systematic research are developed and demonstrate, bullets is 2008BAJ12B04, the phase transition temperature of this solid shaping phase-change material is about 40 ~ 50 DEG C, substantially can meet the requirement of moist closet 8 pairs of temperature.The condensation segment of six roots of sensation gravity assisted heat pipe 6 is inserted in phase-change thermal storage block 5, and the evaporator section of six roots of sensation gravity assisted heat pipe 6 extends outside moist closet 8 and also inserts respectively in the condenser coil 1 of described condenser 15, sees Fig. 3.Be provided with ventilation tubule 11 in freezing and refrigeration room 7, the two ends of ventilation tubule 11 stretch in moist closet 8 respectively, and one end of ventilation tubule 11 is air inlet, and the other end is air outlet 9; Air inlet is provided with mini-fan 12; The ventilation tubule 11 being positioned at freezing and refrigeration room 7 is communicated with drainpipe 10 by three-way pipe, and it is outside that the discharge outlet of drainpipe 10 extends freezing and refrigeration room 7; The ventilation tubule 11 of air outlet 9 side is provided with valve 13.The height of the ventilation tubule 11 that the height of drainpipe 10 is communicated with lower than both sides; The ventilation tubule of air inlet side is horizontal L shape pipe, and bending place is higher than air inlet, and the ventilation tubule 11 of air outlet 9 side is inverted-loop tube.
Operation principle of the present invention is described as follows:
See Fig. 2, during refrigerator refrigeration system work, first the temperature that pipeline inner compressor 14 exports working medium is greater than the temperature of phase-change thermal storage block 5 in moist closet 8, in gravity assisted heat pipe 6 working medium absorption refrigeration working medium heat and evaporate, be condensed into liquid reflux by heat pipe adiabatic section 3 to heat pipe condenser section 4 and complete circulation, reject heat in phase change heat storage material simultaneously; When after refrigeration working medium flows a period of time in condenser coil 1, the temperature of phase-change thermal storage block 5 is greater than the temperature of refrigeration working medium in condenser coil 1, due to the one-way heat conduction effect of gravity assisted heat pipe 6, temperature in phase-change thermal storage block 5 can not back transfer in condenser coil 1, can ensure that in moist closet 8, phase change heat storage material can not cause heat loss by the reverse heat conduction of heat pipe.
When refrigerator refrigeration system quits work, compressor 14 and refrigeration working medium temperature reduce, and the one-way heat conduction effect of the gravity assisted heat pipe 6 on it can ensure that in moist closet 8, heat can not along gravity assisted heat pipe 6 reverse conduction; In moist closet 8, phase-change thermal storage block 5 is by the thermal release of storage in moist closet 8 simultaneously, and the temperature stabilization of guarantee moist closet 8 is constant, guarantees the heat insulation effect of moist closet 8.
See Fig. 3, condenser for refrigerator 15 condensing units mechanism.Gravity assisted heat pipe 6 closed at both ends, in front several condenser coils 1 of heat pipe evaporator section 2 embeddeding refrigerator condenser 15, heat pipe condenser section 4 is arranged in the phase-change thermal storage block 5 of moist closet 8, and the first five root condenser coil 1 of condenser 15 is positioned at below phase-change thermal storage block 5.The part that refrigeration working medium is positioned at condenser 15 leading portion is when the refrigerant system is operating in superheat state, and this mechanism can directly utilize this part heat-recoverable to heat phase change heat storage material, and the heat loss in the diabatic process of gravity assisted heat pipe 6 is more much smaller than common heat transfer.When temperature lower than refrigeration working medium of the temperature of phase-change thermal storage block 5, first the heat crossing hot working fluid conducts heat to gravity assisted heat pipe 6 evaporator section wall, when temperature higher than refrigeration working medium of the temperature of phase-change thermal storage block 5, then conducted heat to environment by condenser coil 1 outer wall, the operating efficiency of condenser for refrigerator 15 is had an impact hardly.
See Fig. 1, the drying sterilizing mechanism of moist closet 8 comprises mini-fan 12, ventilation tubule 11, drainpipe 10, valve 13, air outlet 9, when functions/drying is opened, the micro-air of moist closet 8 is blown in ventilation tubule 11 by mini-fan 12, after ventilation tubule 11 enters refrigerating chamber, its air temperature sharply declines, steam in air can condense into water, flows into drainpipe 10 by the ventilation tubule 11 tilted, and discharges refrigerator, air through super-dry enters in moist closet 8 again, forms circulation.The drying sterilizing function of moist closet 8 is ensured by the air cold cycling closed.
