Incompatibility (both mutually meet and get along well and chemically reacted, and produce the incoagulable gas such as H2, destroy vacuum, this does not allow),
Before making, all structural materials must be all chemically treated, and form the intracavitary material surface contacted with working medium water
Passivating film, hinders further to chemically react between Fe and water.But, the weld seam formed in welding process can not be handled, together
When after a period of operation, because sealing, passivating film such as damage at the reason, the intracavitary of work medium for heat pipe still has a certain amount of
Incoagulable gas is produced so that vacuum is reduced, and the heat transfer property of heat pipe also decreases.
Meanwhile, radial heat pipe is due in structure, and such as hot gas is the acid production with sulphur process gas of high corrosion, to shell
The seal request of body is higher, and leakage is not allowed, therefore, is generally radially examined simultaneously using welding between heat pipe and the side plate of housing
Having considered some improves the expansion factor as caused by thermal stress (such as installing expansion joint additional).Therefore radial heat pipe can not typically stop in equipment
Depart from housing during car, this just brings the difficulty that properties of hot pipe regenerates.
For the longer radial heat pipe of size especially length, after being mounted as in housing, due to deadweight, axis runout
Horizontal line, and the point of case partition connection is that center section can be bent downwardly as fulcrum, end can be upward.

The heat pipe is provided with the first incoagulable gas row at 2 exhaust structures, end socket in the structure of radial heat pipe
The second incoagulable gas air bleeding valve that air valve is used to make on heat pipe, outer tube can be used for the quality rebuilding of radial heat pipe.
Second incoagulable gas air bleeding valve is used in working condition, and it must be positioned at circumferencial direction when heat pipe is installed
Most upper top position；During working condition, peripheral air-flow and internal liquid are circulating, and the media operation in heat pipe is in some temperature
Degree, now, because the incoagulable gas produced in outer tube is gas, density is small, accumulates in the top of intracavitary, as the opening row
After air valve, the saturated vapor pressure of work medium for heat pipe formation can be caught up with these incoagulable gas from working chamber by the air bleeding valve.
After incoagulable gas is caught up with only, the air bleeding valve is closed, radial heat pipe is returned normally, and heat transfer property is recovered.Work as performance
When declining again, this operation is repeated.
Because when discharging incoagulable gas, a small amount of working media in heat pipe can be carried over surely, meanwhile, air bleeding valve is present
