Description
Technical field
The utility model relates to a kind of heat exchanger.Specifically, be the coil exchanger composed in parallel by two independent coil pipes.Be applicable to lower the temperature to the class I liquid I of the flushing liquor in Mechanical Seal Auxiliary System.
Background technology
At present, the class I liquid I of the flushing liquor in Mechanical Seal Auxiliary System is carried out to coil exchanger mainly individual pen coil exchanger and the inside-outside integrated double-coil heat-exchanging device of lowering the temperature.Individual pen coil exchanger wherein due to the length of its coil pipe shorter, the cooled liquid medium passed through in the unit interval is less, makes heat exchange efficiency not high.And inside-outside integrated double-coil heat-exchanging device, the cooled liquid medium passed through within the unit interval is more, can improve heat exchange efficiency, but due to two circle coil pipe be coiled to form with same pipe, pipeline is long, makes outlet pressure compare inlet pressure loss larger.Crushing is crossed conference and is caused system operation cost to rise, the problems such as pressure system element loss is too fast.
Utility model content
Problem to be solved in the utility model is to provide a kind of coil exchanger.Adopt this coil exchanger, can heat exchange efficiency be improved, reduce pressure loss in piping.
The problems referred to above to be solved in the utility model are realized by following technical scheme:
Coil exchanger of the present utility model comprises cylindrical shell, all there is cover at cylindrical shell two ends, and coordinate in sealing shape between cylindrical shell two ends with corresponding cover, two covers all there is pipe joint, two covers there are cooling liquid inlet and cooling liquid outlet respectively, have heat exchanger tube in cylindrical shell, the pipe joint that heat exchanger tube two ends cover with respective barrel is respectively communicated with.Be characterized in there is inner core in cylindrical shell, inner core one end is connected on the medial surface of a corresponding cover, has sleeve between inner core and cylindrical shell.Described heat exchanger tube comprises the first heat exchanger tube and the second heat exchanger tube, and the first heat exchanger tube is positioned between inner core and sleeve, and is coiled in the shape of a spiral on inner core.Second heat exchanger tube is positioned between sleeve and cylindrical shell, and is coiled in the shape of a spiral on sleeve.Described pipe joint comprises the first inlet attack, the first outlet connection, the second inlet attack and the second outlet connection, and first and second inlet attack described is all positioned on a cover, and first and second outlet connection described is all positioned on another cover.Same one end of first and second heat exchanger tube is connected with first and second inlet attack respectively through after corresponding cover, and the other end of first and second heat exchanger tube is connected with first and second outlet connection respectively through after another corresponding cover.
Two covers all have two through holes, first and second inlet attack described is fixed in two through holes on a cover in sealing shape respectively, and first and second outlet connection described is fixed in two through holes on another cover in sealing shape respectively.
As can be seen from the above scheme, owing to having inner core in cylindrical shell, inner core one end is connected on the medial surface of a corresponding cover, has sleeve between inner core and cylindrical shell.Described heat exchanger tube comprises the first heat exchanger tube and the second heat exchanger tube, and the first heat exchanger tube is positioned between inner core and sleeve, and is coiled in the shape of a spiral on inner core.Second heat exchanger tube is positioned between sleeve and cylindrical shell, and is coiled in the shape of a spiral on sleeve.Two heat exchanger tubes are set in a cylindrical shell, and adopt compared with individual pen heat exchanger tube in background technology, extend the time of contact of cooled medium and tube wall, thus substantially increase heat exchange efficiency.
Again because described pipe joint comprises the first inlet attack, the first outlet connection, the second inlet attack and the second outlet connection, first and second inlet attack described is all positioned on a cover, same one end that first and second outlet connection described is all positioned at first and second heat exchanger tube on another cover is connected with first and second inlet attack respectively through after corresponding cover, and the other end of first and second heat exchanger tube is connected with first and second outlet connection respectively through after another corresponding cover.Two heat exchanger tubes are not connected mutually, separate, make the pipeline of single heat exchanger shorter, compared with background technology, thus decrease the loss that outlet pressure compares inlet pressure.
