It can be different.
It that is to say, after compressor 101 stops working, air blower 104 can stop in advance after continuing to blow a short period
Only.Cooling blower 102 is out of service after can continuing again a short period after the stopping of air blower 104.It is laterally passed through due to being provided with
Wear the transverse opening 106 of compressor bin 100, either compressor 101 or the heat (hot-air) of the generation of bottom condenser 103
It is easier to outflow compressor bin 100.And then after compressor 101 is shut down, the thermal Finite generated in compressor bin 100 only leads to
The cooling blower 102 for crossing cross blowing promotes air flowing in compressor bin 100 that can meet cooling requirements, the air blown
Can outflow directly be distributed from laterally outlet.The air blower for laterally exporting and blowing outward is approximately perpendicular to without continuous service as a result,
104, the radiating requirements of compressor bin 100 at this time can be met.
Certainly, if the temperature of compressor bin 100 is not decreased obviously after the stopping of air blower 104.Air blower 104 can also root
It is again started up according to the difference of bottom condenser 103 and environment temperature, to accelerate to radiate.
