Description
Technical field
The utility model relates to freezer compressor heat radiation, particularly relates to a kind of device strengthening freezer compressor heat dispersion, under the operating conditions without the need to consuming additionaling power, reduce the operating temperature of freezer compressor, improve its heat dispersion, extend its working life, reach energy-saving and cost-reducing effect.
Background technique
Along with improving constantly of people's living standard, various appearance design is novel, pack complete refrigerator, refrigerator, food display cabinet, food show case, ice making machine are widely applied to family and commercial field, region is used progressively to expand to rural market from original urban market, exported product application region, except developed country, also expands to some undeveloped countries such as Africa.The critical component of these products is compressor, the rotating speed of compressor is by determining 2900 revs/min of frequency, the speed range developing into frequency-changeable compressor (high-grade goods) is 1600 ~ 4500 revs/min, the heat that compressor rotary speed height produces also increases, and needs heat radiation in time to keep normal temperature.And trendy refrigerator configuration design now, be mainly satisfied with the visual effect of people, namely increase visual sense of beauty.Substantially be adopt the condenser coil that is embedded in the refrigerator back side or side foaming box body by carrying out with the natural convection air of outside to the heat radiation of refrigerator.So the freezer compressor being in confined space to heat radiation, heat insulationly have important requirement.The working life that excellent heat radiation, heat-shielding performance significantly can reduce refrigerator power consumption, improve refrigerating efficiency, extend refrigerator.The all parts of appropriate design, optimization refrigerator has extremely important effect.And the condensate temperature that refrigerator produces in the course of the work is lower, has certain values; The temperature of waste heat that compressor sheds, also far above normal temperature, also has the value of utilization.
Compressor is one of core component of refrigerator, is the heart of refrigerator refrigeration system.At compressor in the process of low pressure refrigerant gas boil down to high pressure superheater gas, produce a large amount of heats, cause temperature cylinder in compressor at about 100 DEG C, to can reach 140 ~ 150 DEG C.These heat overwhelming majority are transported to condenser for refrigerator by refrigerant gas and dispel the heat.Refrigerator keeps for the space of compressor to be a narrow and small confined space, the non-constant of radiating effect, bring very large uncertainty to the applying working condition of compressor, cause the temperatures as high more than 90 DEG C of compressor case, and freezer compressor shell optimum temperature range 43 DEG C to 55 DEG C.Cause the rate of fault of compressor also higher thus, wherein more commonly the refrigeration cycle that causes of compressor head high temperature carbon deposit lost efficacy, and caused refrigerator can not normal refrigeration work.
The different parts temperature difference of compressor housing is large, and especially differ between inlet, outlet between larger and upper and lower two housings and differ comparatively remarkable, its temperature difference can reach 60 DEG C.General suction port spot temperature is relatively low, and compression chamber corresponding position is relatively high, and upper shell temperature is generally much larger than lower shell body temperature.This function not only bad for equipment uses, but also (optimum temperature of freezer compressor lubricant oil is 80 ~ 90 DEG C to produce adverse influence to regular maintenances such as compressor lubrications, easily lost efficacy at 100 DEG C and generated carbon distribution, the capillary channel of blocking refrigerator).Simultaneously compressor bulk temperature is too high, and temperature is uneven, increases compressor compresses running resistance, too increases wearing and tearing and energy consumption, reduces compressor working life.
