Abstract

The utility model provides an energy-saving compressor for domestic refrigerators and other refrigerating systems, comprising a rotary compressor (1), a heat pipe evaporating end (2), a heat pipe condensing end (3), a fin (4) and an actuating medium (5). Because the casing of the compressor is the heat pipe evaporating end, the energy-saving compressor strengthens the heat radiation of a refrigerant under the state of the high temperature after the refrigerant is compressed so as to obviously reduce the temperature of the casing when the compressor is operated. The high-pressure low-temperature refrigerant directly outputted from an exhaust outlet raises the refrigerating performance of the compressor, and the utility model has the advantages of low power consumption and long service life and protects the motor of the compressor so as to provide an energy-saving compressor with low power consumption and high refrigerating performance for the domestic refrigerators and other refrigerating systems.

Description

Energy-saving compressor

The utility model relates to a kind of energy-saving compressor that is equipped with heat-pipe radiator that is used for household electric refrigerator and other refrigeration systems.

In recent years, refrigerator has entered huge numbers of families, reduces the power consumption of household electric refrigerator, the service life of prolongation compressor, has become the common thing of paying close attention to of manufacturing firm and user.United States Patent (USP) (patent No. 4008579) " refrigerating system thermal control device " provides the U type heat pipe that is used for the refrigerator heat radiation.The one end places in the case, and an end places outside the case.Because an end must pass casing, be not suitable for the transformation of the way to existing household electric refrigerator.The heat-pipe radiator that domestic patent (patent No. 87207010) provides be on the condenser of former compressor outlet heat pipe of clamping to increase the area of dissipation of former condenser, but there is thermal contact resistance, because contact area is little, heat-transfer effect is placed restrictions on, and is not remarkable to the direct cooling-down effect of compressor.

The energy-saving compressor that the utility model provides is made up of compressor and heat-pipe radiator.The evaporation ends of heat pipe is made in a compound outer ring on compressor case.Form the heat pipe condensation end by one or several garden pipe on the heat pipe evaporation ends.The pipe outer fin that is with in condensation end garden to increase area of dissipation, is strengthened Heat Transfer of Heat Pipe on Heat Pipe, thereby has been strengthened the direct high efficiency and heat radiation of compressor, has reduced the compressor power consumption, has improved the refrigeration performance of compressor, and compressor electric motor has also been played protective effect.Make it become the novel energy-conserving compressor that power consumption is low, efficient is high, the life-span is long.

The utility model is finished in the following way.

On the shell of Rotary Compressor, the heat pipe evaporation ends is made in outer ring that cavity is arranged of composite welding.One of welding or cluster have the garden pipe of fin on the heat pipe evaporation ends, form the heat pipe condensation end.During compressor operating, become high-temperature high-pressure refrigerant after will compressing from the low-temperature low-pressure refrigerant that air intake duct sucks.The high temperature of cold-producing medium makes the working medium heat absorption explosive evaporation in the heat pipe evaporation ends, and steam rises to the condensation end of heat pipe, discharges the latent heat of vaporization by radiating fin to environment, condenses subsequently.Condensation water utilizes the gravity effect to return evaporation ends, forms working medium heat absorption evaporation → steam to rise → condense → cyclic process that condensation water returns to the condensation end release latent heat of vaporization → steam.Externally, then be that the heat that cold-producing medium produces in compression process is shifted out rapidly, make exhaust outlet of compressor directly export high pressure, refrigerant of low temperature.Thereby improved the refrigeration performance of compressor.Reduce compressor power consumption and organism temperature, protected motor.Its macro-effect is to provide the novel energy-conserving compressor that a kind of power consumption is low, efficient is high, the life-span is long for household electric refrigerator and other refrigeration systems.

Fig. 1 is the structure chart of energy-saving compressor.

Rotary Compressor 1, heat pipe evaporation ends 2, condensation end garden pipe 3, fin 4, working medium 5.

With reference to Fig. 1, heat pipe evaporation ends 2 is made in outer ring of composite welding on the shell of Rotary Compressor 1.The garden of one of welding or cluster band fin 4 pipe 3 is made the heat pipe condensation end on evaporation ends 2.In heat pipe evaporation ends 2, fill with working medium 5.The high-temperature high-pressure refrigerant that produces during compressor 1 operation makes working medium 5 explosive evaporations in the heat pipe evaporation ends 2, steam rises to heat pipe condensation end 3, dispel the heat to environment by fin 4, condensation after the steam release latent heat of vaporization, condensation water returns evaporation ends 2 by the gravity effect.Thus, form a continuous heat transfer cycle.Externally, then be that the high temperature that cold-producing medium produces is after compression reduced to low temperature rapidly.Make exhaust outlet of compressor directly discharge the cold-producing medium of high pressure low temperature.Thereby, improved the refrigeration performance of compressor, reduced power consumption, protected motor, prolonged the service life of compressor.

Fig. 2 is another embodiment of energy-saving compressor.

Outside the casing of Rotary Compressor or piston reciprocating compressor 1, directly two special-shaped heat pipes 2 of clamping are formed an energy-saving compressor.Its advantage is can directly install and use on existing household electric refrigerator or the original compressor of other refrigeration systems.Make it to become the energy-saving compressor of low power consumption, high refrigeration performance, long service life.
