Shell-and-tube heat exchanger is a kind of conventional heat-exchange apparatus, and heat exchanger tube therein uses polytetrafluoroethylmaterial material system
The shell-and-tube heat exchanger made, has the advantages such as acid and alkali-resistance deep-etching, high-low temperature resistant, high, lightweight, the life-span length of intensity, chemical industry,
The industry such as machinery, medicine, electronics is used widely.But typically use polytetrafluoroethylmaterial material to make heat exchanger tube, in work
In running status, because being affected by expanding with heat and contract with cold, result in the phenomenon that the connection between exchanger tubes and tubesheets falls off,
And work operation time, vibrate the biggest.
Utility model content
For drawbacks described above present in prior art, the purpose of this utility model is to provide one and has corrugated heat exchange
The shell-and-tube heat exchanger of pipe, it is to avoid heat exchanger tube is caused because expanding with heat and contract with cold falling off phenomenon with tube sheet, and plays damping
Effect.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of shell-and-tube heat exchanger with corrugated heat exchanger tube, including housing and the pipe being connected to housing upper/lower terminal
Plate, housing is provided with the inlet and outlet of heat transferring medium, two pieces of tube sheets is sequentially connected with pressing plate and closure member, on closure member respectively
It is respectively equipped with the inlet and outlet of product medium, is provided with some heat exchanger tubes between two pieces of tube sheets, tube sheet further respectively has use
With the perforate of fixing tube end, described heat exchanger tube includes straight tube and is located at the straight tube end corrugated tube in order to damping, and
It is connected molding by hot sealing between straight tube with corrugated tube.
Described straight tube one end connects corrugated tube, and is fixed with its homonymy tube sheet by corrugated tube, the straight tube other end
Directly fix with its homonymy tube sheet.
Described straight tube two ends are connected to corrugated tube, and are fixed with corresponding side pipe plate by corrugated tube respectively.
Described corrugated tube includes a bellows piece and a coupled straight length, bellows piece be connected to straight length and
Between straight tube, straight length one end fixes with tube sheet.
Described heat exchanger tube uses polytetrafluoroethylmaterial material to make.
The a length of 2m to 20m of described heat exchanger tube, described Bellows Length is 100mm to 800mm.
Not only connect simple and reliable between exchanger tubes and tubesheets of the present utility model, also there is acid and alkali-resistance deep-etching, resistance to height
Low temperature, intensity is high, lightweight and the feature of life-span length.
