It also avoid different size of foreign material in gas simultaneously and block ground floor drainage screen, second layer drainage screen and the 3rd
Layer drainage screen causes damage, it is ensured that service life；And heat pipe and bridge piece use engagement thread
Connect, as heat pipe damages, when needing to change, change more convenient, decrease labour force, improve
Work efficiency；And the junction of some heat pipes Yu bridge piece is provided with sealing ring, effectively ensure
Some heat pipes are connected with bridge piece and more seal, it is to avoid the phenomenon that leaks air occurs；And heat-insulation layer
It is sheathed on the outer wall of heat pipe, serves the effect of insulation.
This utility model is further arranged to: some described heat pipes and bridge piece all use high temperature resistant,
Acidproof and wear-resisting material is made.
By using technique scheme, it is effectively guaranteed service life.
