Number, causes the integrated heat transfer coefficient of entire case tube heat exchanger relatively low.According to augmentation of heat transfer theory, entire shell-tube type heat exchange is improved
The integrated heat transfer coefficient of device, it is necessary to improve the coefficient of heat transfer of cooling water side in small that side i.e. single tube of the coefficient of heat transfer.Due to penetrating
Stream impact can break the flow boundary layer of cooling water side in ring single tube, improve its coefficient of heat transfer.It therefore, can be by shell-tube type vapour one
Its heat exchanger tube of water- to-water heat exchanger is improved, and tries every possible means to generate certain jet impingement heat transfer tube wall, and then improve cooling water side
The coefficient of heat transfer.Former single tube in one water- to-water heat exchanger of shell-tube type vapour is changed to sleeve-type heat exchanging pipe, casing inner tube four according to above-mentioned thinking
Zhou Buman small sircle holes, circular hole of the cooling water by surrounding under hydraulic pressure effect after sleeve pipe inner tube generate jet stream, impact sleeve
Pipe heat exchange internal face, improves the coefficient of heat transfer of cooling water side, and then promotes the comprehensive heat exchange of entire one water- to-water heat exchanger of shell-tube type vapour
Coefficient.The utility model generates a kind of new shell by the above method is improved traditional one water- to-water heat exchanger of shell-tube type vapour
One water- to-water heat exchanger of tubular type vapour.
Utility model content
The utility model is mainly to provide a kind of new shell-tube type vapor-water heat exchanger, which can carry
The coefficient of heat transfer of high entire heat exchanger.
Technical solution provided by the utility model is：
A kind of shell-tube type vapor-water heat exchanger, includes the heat exchanger cylinder with inlet and outlet, in heat exchanger cylinder

The sealing of baffle one is crossed, inner tube is communicated with the water inlet of heat exchanger cylinder；In the water outlet end of heat exchanger tube, said inner tube passes through baffle
Two seal, and the annular mouth between inner and outer tubes is communicated with the water outlet of heat exchanger cylinder；Said inner tube tube wall is equipped with several
The circular hole of a connection inner and outer tubes.
The utility model is connected between said inner tube and outer tube by ribs in the water outlet end of heat exchanger tube.
The utility model can also be equipped with heat exchange fin in the outer wall of the outer tube.
Heat exchanger tube in traditional one water- to-water heat exchanger of shell-tube type vapour is changed to double-tube heat exchanger by the utility model by single tube, is utilized
Small sircle hole in the inner tube of casing emits jet stream, and the outer tube wall of jet impulse casing destroys the flow boundary layer of outer tube wall,
Its thermal resistance is reduced, the coefficient of heat transfer of cooling water side is improved, to improve the comprehensive heat exchange system of entire one water- to-water heat exchanger of shell-tube type vapour
