The height H and the length L of described projection are respectively: H
Outward=(0.002-0.005) m, H
In=(0.001-0.002) m; L
Outward=(0.005-0.008) m, L
In=(0.003-0.008) m.
The mobile heat exchanging fluid that has separately in described outer heat exchanger tube (3) and the interior heat exchanger tube (4), two kinds of heat exchanging fluids can adverse current or following current.
Be respectively equipped with inlet tube and outlet on described exchange flow pipe and the interior collecting pipe.
The utility model has the advantages of as follows:
1, owing to adopts inside and outside sleeve structure, so can realize heat exchange mutually between the two media, and two kinds of heat transferring mediums, can adopt the adverse current form, at this moment the outlet temperature of heated medium can be higher than the inlet temperature of heat medium, thereby can obtain higher heat exchange efficiency or heat recovery rate, thereby improved the available energy quality of heated medium outlet, two kinds of heat transferring mediums of the present utility model also can adopt the following current form, thereby can reduce the condition of high temperature of heat exchanger tube faster, and can improve the cold end corrosion protection capability of heated medium.And be the condition that adverse current or following current are decided by the user, so convenience and flexibility have been improved.
2, because the hull outside of double wave pipe joint heat exchanger is provided with heat insulation layer, institute is so that its loss of outwards dispelling the heat is reduced to very little.
3, because the external diameter tube wall of inside and outside heat exchanger tube is provided with projection, thus can augmentation of heat transfer, improving the thermal efficiency, heat transfer coefficient can reach 4000-5000W/m
2℃.
4, the utility model is simple in structure, and volume is little, and pressured state is good, and is safe and reliable, and have do not leak, stifled and less scaling characteristics, can realize liquid and liquid, gas and liquid and the high pressure therapeutic method to keep the adverse qi flowing downward and gas heat exchange, have wide range of applications.
