Description

The improvement structure of titanium coaxial sleeve heat exchanger
Technical field
The present invention relates to field of heat exchangers, particularly a kind of improvement structure of titanium coaxial sleeve heat exchanger.
Background technology
Heat exchanger is the equipment of cold fluid that the part heat of hot fluid is passed to, and is the common apparatus of chemical industry, oil, power, food and other many industrial departments, occupies aborning critical role.Because Titanium such as has at the bottom of high temperature resistant, corrosion resistance, light specific gravity, thermal conductivity factor at the characteristics, therefore titanium material and titanium alloy are applied to the heat exchanger production field widely, as existing coaxial sleeve conduit heat exchanger, inner tube is the titanium pipe, outer tube is non-titanium pipe, this titanium tube heat exchanger has good heat conductivity, the advantage such as corrosion-resistant, less scaling, but inner and outer pipes end interface place is comprised of syndeton and sealed filling material, complex structure, make cost high, and sealed filling material must regularly replace, otherwise be easy to leak.Therefore be necessary present technology is further improved.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, the improvement structure of a kind of titanium coaxial sleeve heat exchanger that a kind of structure arranges rationally, result of use is better, sealing property is more excellent is provided.
For achieving the above object, the present invention is by the following technical solutions:
The improvement structure of a kind of titanium coaxial sleeve heat exchanger of the present invention, comprise body and be used to supporting the support of body, described body comprises outer tube and is set in the coaxial threaded shape inner tube in outer tube, by non-titanium, prepared by described outer tube, by the titanium material, prepared by described inner tube, the end of described outer tube, inner tube connects by the titanium steel composite connecting pipe, and described titanium steel composite connecting pipe is provided with the refrigerant inlet/outlet pipe.
Further, described titanium steel composite connecting pipe is made through explosion cladding process by titanium material tube connector and non-titanium tube connector, and described titanium material tube connector is anterior to be welded and fixed with the inner tube end, and described non-titanium tube connector rear portion and outer tube end are welded and fixed.
Further, described two supports are symmetrically set in the body inboard.
Further, described body oval in shape is wound around or circular the winding.
Further, described refrigerant inlet/outlet pipe is located on non-titanium tube connector.
After adopting said structure, beneficial effect of the present invention is: the present invention adopts titanium steel composite connecting pipe front end titanium material part to weld with the titanium inner tube, the non-titanium part in rear end and non-titanium outer tube welding, adopt solder technology that the inner and outer pipes joint is sealed effectively, improved bonding strength, need not regularly replace packing material, and be difficult for occurring fluid leakage problems in body.
