The efficient radiating type compressor housing is characterized in that the upper cover is formed by punching aluminum alloy material. By adopting the efficient radiating type compressor housing, the heat distribution in a compressor is improved, and the heat in the compressor housing can be timely and quickly radiated to the outside, so that reflowing refrigerant gas can be greatly prevented from heating due to excessively high temperature in the compressor, and as a result, the refrigerating efficiency of the compressor is improved.
Description
(i) technical field: the utility model relates to totally-enclosed reciprocating piston type refrigerating compressor for refrigerator and manufactures field, especially a kind of high-efficient heat-dissipating compressor housing.
(ii) background technique: along with the reinforcement of the world and Environmental Protection in China consciousness, the environmental protection and energy saving product is subject to the favor of every profession and trade, develops energy saving and environment friendly product, has formed a kind of trend.As the refrigerating compressor for refrigerator industry, the product of exploitation is floride-free product at present, as the R600a product, be energy-conserving and environment-protective especially, the pure nature product be easy to get, requirement according to the International Environmental Protection tissue, forbidden the product of production and selling to pollution of atmosphere, the disposal of pollutants of minimizing to atmosphere, freezer compressor is also more and more higher to the requirement of environmental protection, performance to compressor is also more and more higher, along with the enforcement of national energy-saving subsidy and the upgrading of Europe energy consumption, exploitation energy-saving, environment-friendly and high-efficiency compressor has cheaply become primary task at present.As freezer compressor, a lot of go-beyond technologies have started to be widely used, as direct air-breathing technology, the high efficiency motor technology, reduce the friction horsepower technology, at present in order to improve the performance of compressor, people are in the heating that reduces compressor, and the aspects such as minimizing suction superheat conduct in-depth research.Research shows when compressor operating, the high temperature produced while mainly being compressor compresses, the fricative high temperature of mechanical motion pair, also have machine operation to send out high temperature thermogenetic, the high temperature that these factors produce is transmitted by refrigeration agent and lubricant oil, after the compressor temperature raises gradually, heat exchange along with refrigeration agent and oil, case temperature also reaches higher temperature, surface of shell needs fast outwards radiations heat energy, only have after the enclosure interior temperature descends, the refrigerant gas returned from compressor return air pipe just can reduce the higher heat of absorption, not so, after the enclosure interior temperature raises, compressor internal refrigeration storage agent gas will expand, gas specific volume increases, the density of refrigerant gas diminishes, the mass flow rate be drawn in cylinder will reduce, thereby reduced the refrigeration of compressor.Yet up to now, in order to improve the refrigeration of compressor, people's research direction is focused on all the time aspect the heating value that reduces the compressor inner body, and adopted many technology to reduce the operating temperature of compressor, many technology have reached the stage of best, therefore by reducing the internal work temperature of compressor, the refrigeration that improves compressor is very difficult.On the other hand for a long time, in traditional design, the material of the upper cover of compressor housing and lower casing is to adopt the materials such as 08AL cold punching steel plate or hot rolling acid-cleaning plate, because cold punching steel plate and acid-cleaning plate material are steel, and the thermal conductivity of steel is 16 watts/meter. degree, its heat-transfer effect is lower, can not make the heat of compressor inside outwards distribute in time, the raising of compressor cooling effect is restricted.
(iii) summary of the invention: the purpose of this utility model is exactly will solve the compressor cooling effect to be difficult to the problem further improved, and a kind of high-efficient heat-dissipating compressor housing is provided.
Mentality of designing of the present utility model is: avoid reducing the problem that the compressor heating value is very difficult, set about reducing compressor internal work temperature from the heat radiation aspect.For compressor housing, it is unallowed that the perforate on housing of conventional way is dispelled the heat, and selects the high material of thermal conductivity to make compressor housing, the heat that makes compressor inside in time outwards conduction to distribute be effective method.Research shows, compressor in the course of the work, various heatings are collected, heat upwards transmits, working as warm refrigerant gas and upper cover, when lower casing carries out heat exchange, because the refrigerant gas returned from muffler only has degree more than 30, when the warm refrigerant that the colder refrigerant gas returned is interior with housing and oil contact, heat exchange occurs rapidly, the temperature of the refrigerant gas returned like this raises, because the proportion of refrigeration agent is heavier than oil, after so refrigeration agent returns, a part is molten in oil, a part is evaporated, the hot steam refrigeration agent reaches and oily aerosol and upper cover generation heat exchange, the temperature of upper cover raises, by test, show, the temperature of upper cover is than the high 10 degree left and right of lower casing temperature, therefore, preferentially upper cover is used to the material of good heat conductivity, can effectively accelerate the heat transfer rate of compressor internal heat gas, internal refrigeration storage agent gas temperature is reduced.
Specific design scheme of the present utility model is: for existing compressor housing, improved, it has upper cover and the lower casing docking forms, and it is characterized in that: upper cover is to adopt the aluminum alloy material punching to form.
The docking periphery punching of lower casing described in the utility model has the flange of horizontal arrangement, the docking periphery punching of upper cover has " U " type crimping, " U " type crimping level is horizontally-arranged, and inwardly, the flange of lower casing is inlaid in " U " type groove of " U " type crimping of upper cover and forms seal structure opening.
The upper cover of the utility model middle shell has adopted aluminum alloy material to make, because the coefficient of the ratio of heat transfer coefficient Steel material of aluminum alloy material wants large, so that the heat spread out of in unit time and unit area is wanted is high a lot.By data, can find, the thermal conductivity of general aluminum alloy is 200 watts/meter. the degree left and right, and the thermal conductivity of steel is 16 watts/meter. the degree left and right, by contrast, the heat-conducting effect of aluminum alloy is more than 10 times of steel, after the housing of visible use aluminum alloy, the heat-transfer effect of compressor can be greatly improved, and test shows, after the upper cover 6 that uses aluminum alloy, the temperature of the compressor inside 15-25 degree that can descend, the COP of compressor improves approximately 4%.Very ripe today in Compressor Technology, the every raising 1% of COP is all very difficult.Its reason is the high temperature produced when compressor compresses, the fricative high temperature of mechanical motion pair, also have machine operation to send out high temperature thermogenetic, the high temperature that these factors produce is transmitted by refrigeration agent and lubricant oil, after the enclosure interior temperature raises gradually, heat exchange along with refrigeration agent and oil, case temperature also reaches higher temperature, after the enclosure interior temperature raises, as radiating and cooling not in time, compressor internal refrigeration storage agent gas will expand, gas specific volume increases, the density of refrigerant gas diminishes, the mass flow rate be drawn in cylinder will reduce, certainly will reduce the refrigeration of compressor.The utility model is due to the aluminum alloy upper cover that has adopted high thermal conductivity coefficient, there is splendid heat-transfer effect, greatly improved the thermal diffusivity of housing, the temperature of enclosure interior is outwards distributed fast in time, thereby the temperature that has reduced enclosure interior has reached the purpose of mentioning compressor performance.
Lower casing in the utility model still adopts punching of the steel plate, to guarantee its installation strength needs.Upper cover lower casing in the utility model has changed original welding structure, adopts " U " type crimping and flange to press the embedding structure, the distortion of having avoided being welded, and beautiful shape, particularly facilitated the connection processing of two kinds of different materials.
