Kind can effectively be radiated using coolant liquid, and radiating efficiency is high, avoided the excessively high damper cylinder barrel of local air temperature and used
Finish rolling seamless steel pipe.
Technical solution adopted by the utility model to solve its technical problems is：A kind of damper cylinder barrel finish rolling seamless steel
Pipe, including steel pipe body, the steel pipe body include inner and outer tubes, said inner tube is structure as a whole with outer tube bottom surface, interior
Pipe inner sleeve is in outer tube, and inner tube and outer concentric tube；The outer tube upper end is provided with inlet, lower end is provided with liquid outlet, described
Inlet and liquid outlet be connected separately with inlet pipe and outlet tube road；The inner tube outer surface is around inner tube periphery mask
Have a helical teeth, the helical teeth and inner tube be an integral molding structure and around inner tube outer peripheral surface be distributed in inlet with
Interior pipe surface between liquid outlet；The outer tube outer surface has at least one cyclic annular anchor ear along outer tube circumferencial direction.
In actual use, the inlet of seamless steel pipe connects inlet pipe, and by identical with inlet pipe pipeline
The pump housing is pumped into coolant liquid into the cavity between inner tube and outer tube, and coolant liquid is by cavity then from liquid outlet via outlet tube road
Discharge.In the process, coolant liquid carries out heat exchange, the heat that inner tube is generated when damper is buffered with inner tube in cavity
It can be carried out cooling heat by coolant liquid, improve radiating efficiency.
Further, in order to improve the surface area of helical teeth, heat exchange area, the outer end face of helical teeth are improved
With at least one indent groove portion.
Further, outside evagination is distinguished at the inlet and liquid outlet of outer tube has circular extension, the extension
Portion outer end is integrally formed with annular flange, the flange, extension and outer tube integral structure.Flange and extension can be convenient for outer
It manages and to be sealedly connected and fixed with inlet pipe and outlet tube road.
Further, in order to improve the load capacity of outer tube, outer tube outer surface is evenly spaced on that there are three cyclic annular anchor ears.
Cyclic annular anchor ear can correspond to seamless steel pipe for when producing cylinder barrel, effective cylinder drum outer wall load capacity to reduce detonation risk.
The utility model has the beneficial effects that damper cylinder barrel finish rolling seamless steel pipe provided by the utility model, design
Inner tube and the dual pipeline of outer tube, can introduce coolant liquid in pipeline and cool down to inner tube, radiate relative to traditional air, dissipate
The thermal efficiency is higher, and can effectively avoid that local air temperature is excessively high, extends the service life of damper.
Detailed description of the invention
