Further technical scheme, described ridge is the arc ridge outwards formed from inner pipe wall, between two adjacent arc ridges, is the depression of arc.
But described ridge is not limited to said structure, can, for the inverted U ridge outwards formed from inner pipe wall, between two adjacent inverted U ridges, be also U-shaped depression.
Described ridge can also be the heat exchanger fin outwards formed from inner pipe wall.
Above-mentioned water heater in central heating comprises two described heat exchanger tubes, and the outer tube of two described heat exchanger tubes utilizes a straight tube to be communicated with, and is respectively equipped with the first heat transferring medium entrance and the outlet of the first heat transferring medium on two described outer tubes;
The inner tube of two described heat exchanger tubes utilizes a U-shaped elbow to connect, and the opening end of two described inner tubes is respectively the second heat transferring medium entrance and the outlet of the second heat transferring medium.
Further technical scheme, described the second heat transferring medium entrance and the second heat transferring medium exit all are welded with union elbow.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. be located at the ridge top in the inner tube outside and the madial wall inscribe of outer tube in the utility model, many ridge is divided into a plurality of zonules that are not interconnected by the cavity between outer tube and inner tube, first heat transferring medium of flowing through in each zonule fully contacts with heat exchange surface, heat exchange is abundant, improves heat exchange efficiency.
