Preferably, as shown in Figure 1, including two heat pipes, the horizontal component 102 of described two heat pipes in the system It is respectively facing opposite direction and extends by two symmetrical heat pipes of setting, can absorb heat in different directions, meet heat exchange Demand.

Preferably, communicating pipe is arranged between the vertical pipe 103 of adjacent heat pipe.Such as two heat pipes adjacent to each other Communicating pipe 107 is set between vertical pipe 103., can be even to avoid uneven heating between heat pipe evaporation ends by the way that communicating pipe is arranged, it is real Pressure between existing heat pipe is balanced, defect caused by avoiding the uneven heating between different heat pipes even.

Preferably, constantly subtracting the distance between adjacent communicating pipe 107 from 103 lower part of vertical pipe to 103 top of vertical pipe It is small.This purpose is in order to which more communicating pipes are arranged, because of flowing up with fluid, fluid is constantly heated, with stream Body is constantly heated, heated more and more uneven in different heat pipes, therefore by above-mentioned setting, can guarantee to flow in fluid Reach pressure equilibrium as soon as possible in the process.

Preferably, constantly subtracting the distance between adjacent communicating pipe 107 from 103 lower part of vertical pipe to 103 top of vertical pipe Small amplitude is increasing.It is found through experiments that, above-mentioned setting, can guarantee more excellent in process fluid flow to reach faster Pressure is balanced.This is also the optimal mode of communicating got and largely studying pressure changes in distribution rule.

Preferably, from 103 lower part of vertical pipe to 103 top of vertical pipe, the diameter of communicating pipe 107 is continuously increased.This mesh Be to be arranged and guarantee bigger connection area, because of flowing up with fluid, fluid is constantly heated, with fluid It is continuous heated, it is heated more and more uneven in different heat pipes, therefore by above-mentioned setting, it can guarantee to flow in fluid Reach pressure equilibrium in journey 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 107 It is increasing.It is found through experiments that, above-mentioned setting, can guarantee that more excellent in process fluid flow to reach pressure equal faster Weighing apparatus.This is also the optimal mode of communicating got and largely studying pressure changes in distribution rule.

Although the utility model has been disclosed in the preferred embodiments as above, the utility model is not limited to this.Any Field technical staff can make various changes or modifications without departing from the spirit and scope of the utility model, therefore this is practical Novel protection scope should be defined by the scope defined by the claims..
