Preferably, from 103 lower part of vertical pipe to 103 top of vertical pipe, the diameter of communicating pipe is continuously increased.This purpose is
Guarantee bigger connection area to be arranged, because of flowing up with fluid, fluid is constantly heated, as fluid is continuous
It is heated, it is heated more and more uneven in different heat pipes, therefore by above-mentioned setting, can guarantee in process fluid flow
Reach pressure equilibrium as soon as possible.
Preferably, from 103 lower part of vertical pipe to 103 top of vertical pipe, the ever-increasing amplitude of the diameter of communicating pipe is got over
Come bigger.Be found through experiments that, above-mentioned setting, can guarantee in process fluid flow it is more excellent faster reach pressure equilibrium.
This is also the optimal mode of communicating got and largely studying pressure changes in distribution rule.
Although the present invention has been disclosed in the preferred embodiments as above, present invention is not limited to this.Any art technology
Personnel can make various changes or modifications, therefore protection scope of the present invention is answered without departing from the spirit and scope of the present invention
When being defined by the scope defined by the claims..
