It is divided into reversed return type and off course formula in the similarities and differences for recycling distance in water conduit tube and return water main pipe by heating agent by system. In the application of the fluid heating snow-melting system cloth form of tubes and actual items at home and abroad studied, system is mostly direct return system.

The characteristics of off course formula is that return water main pipe pipeline trip is shorter, saves initial cost, is easy to construct.However this system is also It is to have certain limitation, each loop resistance of system is uneven, and Yi Fasheng " off-leveling " causes away from heat source proximal end pipeline flow Greatly, remote traffic is small, i.e., good away from heat source proximal end road face snow melt effect, face snow melt effect in distal end road is poor, that is, on entire road Snow melt is uneven.

Road pipe laying mode is mostly rectangular-ambulatory-plane stringing, but this easy gas collection of cloth form of tubes pipe content, and the following pipeline in road surface It can not be exhausted, therefore gas in pipelines can be cumulative, increase system resistance, be unfavorable for the flowing of water, weaken heat exchange effect Fruit cannot reach optimal snow melt effect.

Summary of the invention

Reversed return system is used when inventive pipeline is laid, the on-way resistance of each loop consumption is essentially identical, every snow melt The flow of pipeline is also identical, snow melt uniform in effect, is not in the snow melt pipeline heat close from heat source, the snow melt pipeline remote from heat source Not hot phenomenon realizes the purpose of the comprehensive snow melt of road.

Through-type piping mode is used when the stringing of road surface, elbow is not present in the following pipeline in road surface, therefore will not go out in pipeline Existing gas collection phenomenon, reduces system resistance, is conducive to the flowing of water, enhances heat transfer effect, improves snow melt effect.

To achieve the above object, the invention adopts the following technical scheme:

According to an aspect of the present invention, a kind of through-type heating road snow-melting system of same journey is provided, the system comprises heat Source, at least one first heat exchange station being arranged on the left of road and at least one second heat exchange station being arranged on the right side of road, Being basically parallel to for connecting with the first heat exchange station road extending direction is arranged on the left of road first is changed for water conduit tube, with first Heat stations connection is basically parallel to the first return water main pipe and be basically perpendicular to road that road extending direction is arranged on the right side of road Road extending direction and cross road surface and be arranged in road surface connection described first below for the more of water conduit tube and the first return water main pipe A first straight pipe, the second water supply for being basically parallel to road extending direction and being arranged on the right side of road being connect with the second heat exchange station Main pipe, being basically parallel to of being connect with the second heat exchange station the second return water main pipe that road extending direction is arranged on the left of road and Road surface is crossed basically perpendicular to road extending direction and is arranged in road surface connection below described second for water conduit tube and second Multiple second straight pipes of return water main pipe,
