Abstract
The present invention relates to a kind of phase change cooling method for condenser of refrigerator and device thereof, can be used for the domestic refrigerator refrigeration system of intermitten service.
Phase change cooling method is when utilizing the material phase transformation, under phase transition temperature, can absorb or emit the characteristic of latent heat of phase change, and be the heat transfer type of its cooling with the heat conduction of phase change material, this has just changed the type of cooling that traditional condenser for refrigerator adopts natural convection air, thereby the heat transfer coefficient of condenser is improved greatly, condenser structure compactness, volume-diminished, with low cost.And the domestic refrigerator energy consumption is descended, and coefficient of refrigerating performance improves, and running rate reduces, and freezer temperature descends, and the refrigerator floor space reduces.
Description
The present invention relates to a kind of phase change cooling method for condenser of refrigerator and device thereof, be adapted to the domestic refrigerator refrigeration system of intermitten service.
Over past ten years, abroad for the phase transformation thermal control, phase change energy storage technology has carried out basic research widely and some engineerings are used.In space technology, be used for the thermal control of lunar rover signal operation device; In energy technology, phase change device is used for the storage of solar energy daytime, then is used for night to the solar house heat supply; And in Refrigeration Technique, be used for the refrigerator cold insulation after refrigerator cuts off the power supply.But up to now, in numerous at home and abroad refrigerators, do not seen and adopted phase change cooling method and design the condenser for refrigerator example of manufacturing and relevant technical literature.
Traditional domestic refrigerator condenser, no matter be venetian blind type, wire type, case back of the body formula, built-in be its air-circulation features all with the free convection of air.The natural convection air heat exchange, in many heat exchange modes, the coefficient of heat transfer is minimum, causes the condenser heat-transfer surface excessive, and consumptive material is many, and volume is big, the cost height, radiating effect is poor.
The invention provides a kind of effective cooling means, fundamentally change traditional type of cooling of domestic refrigerator.According to the condenser that this method manufactures and designs, efficient, compact, cheap.Be used for the domestic refrigerator refrigeration system, energy consumption of refrigerator is descended, running rate reduces, and coefficient of refrigerating performance improves, and freezer temperature descends, and the refrigerator floor space reduces, and star improves.
The cooling procedure of phase change cooling method for condenser of refrigerator is finished like this.
The refrigeration system of general domestic refrigerator is intermitten service, when refrigeration system is worked, using the phase transformation condenser of phase change cooling method design also starts working simultaneously, the phase transformation condenser is in the atmosphere distribute heat, place the phase change material in the condenser, under phase transition temperature, absorb latent heat of fusion, by the solid-state liquid state that becomes, the cold-producing medium in the refrigeration system is then emitted heat and condensation.When refrigeration system quit work, the phase change material in the condenser under phase transition temperature, discharged crystallization latent heat to atmosphere, multiple become by liquid state solid-state, until the refrigerator refrigeration system beginning of working for the second time.The phase transformation condenser goes round and begins again like this, periodic duty.
Utilize the material phase transformation to cool off, its heat transfer type is the heat conduction of phase change material, this just changes the traditional natural convection air type of cooling of condenser for refrigerator, thereby the condenser heat transfer coefficient is improved greatly, radiating effect improves, condenser structure compactness, volume-diminished, and be convenient in refrigerator, be provided with.
Fig. 1 is the embodiment of phase change cooling method for condenser of refrigerator, flat phase transformation condenser.
Fig. 2 is second embodiment of phase change cooling method for condenser of refrigerator, cartridge type classification phase transformation condenser.
Fig. 3 is the 3rd embodiment of phase change cooling method for condenser of refrigerator, flat classification phase transformation condenser.
Condenser coil 1, shell 2, phase change material 3, spiracle 4.
With reference to Fig. 1, Fig. 2, Fig. 3, condenser coil 1 is close to shell 2, or soldering becomes an integral body.Phase change material 3 places in the shell 2, and the upper end of condenser casing 2 is provided with a spiracle 4.
With reference to Fig. 1, Fig. 2, Fig. 3, further specify the course of work of phase change cooling method for condenser of refrigerator.
When refrigerator refrigeration system was started working, the A of the cold-producing medium autocondensation coil pipe 1 that temperature is higher end entered in the pipe, because condenser coil is close to shell 2, a part of cold-producing medium heat is dispersed to atmosphere by shell 2; Another part heat is then by placing condenser coil 1 outer phase change material 3 to transmit heat in the mode of heat conduction, cold-producing medium is condensation after emitting heat, and autocondensation coil pipe 1B holds discharge, after 3 of phase change materials absorb the latent heat of fusion, under phase transition temperature, by the solid-state liquid state that becomes.
When refrigerator refrigeration system quit work, phase change material 3 continued to the atmosphere release heat by shell 2, under phase transition temperature, emit crystallization latent heat after, become solid-stately by liquid state again, finish a cyclic process.
Fig. 2 and Fig. 3 illustrate the cold level system of classification, and the classification cooling can be secondary cooling or multistage cooling, in fractional condenser, places the phase change material 3 of different phase transition temperatures.
The present invention is selected: paraffin wax class, fatty acid and derivative thereof, the hydrate of inorganic salts are the phase change material of phase change cooling method for condenser of refrigerator, and these phase change materials can be one-components, two components, or many components.
The phase transition temperature that the present invention selectes is 35 ℃ to 80 ℃ Celsius.
