Heat exchange is the high-temperature gas being just discharged from compressor 1 into 4 each sections of heat transferring medium of outer tube, therefore heat transferring medium and interior
Water temperature difference in pipe 3 is larger.And traditional heat exchange mode, along with heat during flowing in outer tube 4 due to heat transferring medium
Amount loss, therefore temperature is lower and lower, in the endpiece of outer tube 4, the temperature difference of heat transferring medium and water will greatly reduce.Due to heat transfer speed
The rate=driving force of heat transfer (temperature difference)/heat transfer resistance, temperature difference the high also faster with regard to rate of heat transfer.So the heat exchange side of the present invention
Formula is compared with traditional heat exchange mode, faster more efficient.The outer tube 4 can be divided into two sections, three sections, four sections it is even more, when
Right 4 hop count of outer tube more at most heat transfer rate is faster, and better effects can be reached by being divided into three sections under normal conditions.

Only heat conductivility is more preferable, and structural strength is more preferably.Specifically, since inner tube 3 needs pressure-bearing, and pure aluminum material intensity is not
Foot, cannot be directly applied in inner tube 3.If the aluminium content in 1070 aluminium and 1050 aluminium has all reached 99% or more, although its
Heat conductivility is all fine, but its intensity deficiency is so cannot apply on bearing pipe.Inner tube 3 belongs to bearing pipe, needs
The material for selecting intensity larger makes, although copper intensity and heat conductivity are fine, it is not only expensive, but also weight
Greatly.In conventional understanding, the heat conductivility of aluminium alloy is significantly less than fine aluminium, and the heat conductivility of aluminium alloy and wherein aluminium content
It is proportionate, and the aluminium alloy aluminium content in this programme only has 70% or so, but its heat conductivility but basically reaches fine aluminium
Level, and structural strength is much improved.Under the premise of not sacrificing its heat conductivility, reach such intensity greatly
