The outer wall of said inner tube is provided with radiating fin, and the inwall of inner tube is smooth arc inwall, and inner tube is placed in heat exchanging chamber, inner tube two
Outer tube is extended at end and both ends difference formed inner tube entrance and inner tube outlet, the part between outer wall of inner tube and outer tube wall are changed
Hot chamber forms heat transferring medium flowing region.Such coaxial sleeve heat exchanger, because inner tube wall is smooth arc tube wall, water flows into
Exchanged heat in inner tube, because inner tube wall is smooth arc tube wall, water is difficult to form incrustation scale in interior Bottomhole pressure, compared to tradition
Inner tube wall is threaded interior walls, and water easily forms incrustation scale in the threaded interior walls of inner tube, and incrustation scale reduces changing for coaxial sleeve heat exchanger
The thermal efficiency, coaxial sleeve heat exchanger of the present utility model is because inner tube wall is smooth, coaxial sleeve heat exchanger usage time length
Be not in incrustation scale, ensure the heat exchange efficiency and effect of coaxial sleeve heat exchanger, improve the practicality of coaxial sleeve heat exchanger.
The utility model can also use following technical measures to solve：
Further, a heat conduction protective layer is additionally provided with the smooth arc inwall of said inner tube.By being provided with heat conduction
Protective layer, water are difficult to be bonded in heat conduction protective layer in heat transfer process, incrustation scale or impurity, improve the heat exchange effect of coaxial sleeve heat exchanger
Rate.
Further, the inner tube inlet of said inner tube and inner tube outlet each extend over out the front-end and back-end of outer tube.
Further, the male-pipe that the outer tube distorts for ease of outer tube.By being provided with external screw thread outer tube, outer tube can
Easily to be distorted according to use environment, space, the adaptability of coaxial sleeve heat exchanger is improved.
Further, the radiating fin in a spiral manner winding on the outer wall of inner tube.
Further, the radiating fin is to be welded to connect with inner tube.
Further, the radiating fin is Integratively formed with inner tube.
Further, the pipe thickness of said inner tube is less than the height of radiating fin.
The beneficial effects of the utility model are as follows：
（1）Coaxial sleeve heat exchanger of the present utility model, because inner tube wall is smooth arc tube wall, water flows into inner tube
Inside exchanged heat, because inner tube wall is smooth arc tube wall, water is difficult to form incrustation scale in interior Bottomhole pressure, compared to traditional inner tube
Inwall is threaded interior walls, and water easily forms incrustation scale in the threaded interior walls of inner tube, and incrustation scale reduces the heat exchange effect of coaxial sleeve heat exchanger
Rate, coaxial sleeve heat exchanger usage time length of the present utility model is also not in incrustation scale, ensures changing for coaxial sleeve heat exchanger
The thermal efficiency and effect, the practicality of coaxial sleeve heat exchanger is improved, be especially suitable for art of heat pumps and use.
