Specific implementation mode
In Fig. 1, the ground terminal of three core one-phase power source plugs 1 is passed through wire power connection outcase of refrigerator.Three core single-phase electricities
The other two terminal of source plug 1 is in parallel with the power input of refrigerator circuit 2 by conducting wire.Refrigerator circuit 2 is existing
All kinds of refrigerator circuits in technology（Type is controlled electronically in Mechanical course）, no longer describe.In refrigerator circuit 2
Two power supply circuits being connected with compressor operating winding on draw two conducting wires and come, as compressor operating winding exit
8.Compressor operating winding exit 8 is in parallel with the power input of cooling fan power supply 3 by conducting wire, this just may make cooling fan
Power supply 3 it is synchronous with the compressor of refrigerator it is electric or or power-off.The power output end of cooling fan power supply 3 and compressor cooling fan 5
It is in parallel.Compressor cooling fan 5 is mounted on beside compressor, can be installed in the medial surface of compressor installation site, so more
Be conducive to the quick discharge of heat.It is straight with a 12V to the compressor cooling fan 5 of its heat transmission due to compressor small volume
Flowing small electric fan can meet the requirements（That is that common heat emission fan with square frame of computer or electronic instrument）, and turn
Speed can reduce use, therefore be supplied power for DC10V or so voltages.
Cooling fan power supply 3 is most common lower pressure rectifier power supply in the prior art, in step-down transformer it is available
220/9V's, power 2W is just.The DC voltage of 11V or so can be obtained after bridge rectifier rectification and capacitor filtering.
Compressor cooling fan 5 is It is not necessary to continuously run, because compressor temperature is not high when the temperature of the surroundings is low, to it
Blowing heat dissipation has little significance to improving coefficient of refrigerating performance.Therefore, the power output end of cooling fan power supply 3 and compressor cooling fan 5 it
Between be also in series with compressor cooling automatic switch 4.Compressor cools down automatic switch 4, can use the temperature of bimetallic sheet structure certainly
