Hold constant.
Preferably, along the flow direction of fluid in thermal-collecting tube 1, the distributed quantity of intercommunicating pore 8 is more and more, further excellent
Choosing, the amplitude that the connection hole number constantly increases are continuously increased.
It is identical by the Distribution Principle of above-mentioned quantity and area reduction principle, compared with connection hole number is identical, lead to
Cross distributed number to reduce circulation area.
Find in actual experiment, the area of intercommunicating pore 8 can not be too small, it is too small if can cause the increase of flow resistance,
So as to the decrease for causing to exchange heat, the area of intercommunicating pore 8 can not be excessive, and area is excessive, can cause the reduction of heat exchange area, so as to drop
Low heat transfer effect.Equally, the cross-sectional area of thermal-collecting tube 1 can not be excessive, excessive to cause what is be distributed in tube plate structure unit length to change
Heat pipe is very few, again results in heat transfer effect variation, and thermal-collecting tube flow area can not be too small, too small that flow resistance can be caused to increase
Plus, so as to cause heat transfer effect to be deteriorated.Therefore between intercommunicating pore 8 and thermal-collecting tube cross-sectional area and its adjacent intercommunicating pore 8 away from
From must being fulfilled for certain requirement.
Therefore, the present invention is the thousands of numerical simulations by multiple various sizes of heat collectors and test data,
In the case of meeting industrial requirements pressure-bearing（Below 10MPa）, in the case where maximum heat exchange amount is realized, the optimal thermal-arrest for summing up
The dimensionally-optimised relation of device.
