Shown in Fig. 4, evaporation ends flow to the first line between the center of circle and the center of circle of evaporation ends 6 at 9 place of condensation end pipeline, adjacent gas
Form the first line, third line between 4 center of circle of body exit passageway and the center of circle of evaporation ends 6, the first line and the second line it
Between the first angle for being formed be equal to the second angle formed between the first line and third line.Similarly, 4 institute of Gas outlet channels
The center of circle and the center of circle of evaporation ends 6 between the 4th line, adjacent evaporation ends flow to 9 center of circle of condensation end pipeline and evaporation ends
The 5th line, the 6th line are formed between 6 center of circle, the third angle formed between the 4th line and the 5th line is equal to the 4th
The 4th angle formed between line and the 6th line.On namely in circumferential direction, evaporation ends flow to condensation end pipeline 9 and outlet
Channel 4 is uniformly distributed.
Pass through above-mentioned setting, it is ensured that evaporation ends flow to condensation end pipeline 9 and Gas outlet channels 4 to inlet gas into
Row absorbs heat uniform, avoids local heating uneven.Gas outlet channels 4 can continue to participate in heat exchange after absorbing heat, by heat
Evaporation ends are passed to by fin.
In numerical simulation and it was found that, Gas outlet channels 4 and evaporation ends flow to the caliber difference of condensation end pipeline 9
Cannot be too big, can not be too small, cause if too big Gas outlet channels 4 and evaporation ends flow to the distribution of condensation end pipeline 9 away from
Too far away, the gas converting heat between causing channel 4 and evaporation ends to flow to condensation end pipeline 9 is bad, causes overall heat exchange uneven,
Cause the distance that Gas outlet channels 4 and evaporation ends flow to the distribution of condensation end pipeline 9 too close if too small, causes close to inlet tube
The gas converting heat of the outer wall of the gas of 11 outer wall and/or close evaporation ends 6 is bad, and the gas in whole inlet tube 11 is caused to change
Heat is uneven；Same reason, the angle between adjacent fins 12 cannot be too big, and it is few to lead to be distributed fin if too big, changes
Thermal effect is excessively bad, also result in Gas outlet channels 4 and evaporation ends flow to the distribution of condensation end pipeline 9 quantity it is very little, cause
The uneven and heat transfer effect that exchanges heat is bad, and similarly, the angle between adjacent fins 12 cannot be too small, leads to fin if too small
Distribution is too close, and flow resistance increases, and Gas outlet channels 4 and evaporation ends flow to the caliber of condensation end pipeline 9 and are not much different,
But they differ greatly with the exchange capability of heat of homalographic, therefore it is uneven to exchange heat in such cases, causes heat transfer effect bad.
Therefore it needs to determine best size relationship by a large amount of numerical simulation and its experiment.
