One end of the traction core shaft is provided with a pull ring; the housing is connected with an opening part at the part of the outside of one end of the cooling pipe. The shell-and-tube cooler not only has high heat exchange efficiency but also has the advantages of convenient maintenance and cleanness of heat exchange elements, high operating reliability, small size, simple structure and material saving.
Description
Technical field
The utility model relates to heat-exchange apparatus or device technique field, is provided with the heat-exchanger rig of cooling tube in especially a kind of.
Background technology
In be provided with cooling tube shell and tube cooler be widely used in all kinds of gas compressor units, in order to satisfy the requirement of compressor, improve its cooling performance, normally reach desirable heat exchange effect, therefore make cooler become parts the hugest in the Compressor Group by increasing heat exchange area.How to improve heat exchange efficiency to greatest extent, make that the volume and weight of the cooler minimum that becomes is the lightest, be one of hot subject of gas compressor area research always.
In the prior art, have a kind of the applicant of being to produce, it is to adopt the heat exchanger tube rectangular member formula structure of large stretch of fin in addition in cooler core, than the normal optical heat exchange of heat pipe, has improved heat exchange efficiency, has reduced volume and weight.But in application, find several problems:
(1) maintenance is difficult: because inter fin space is from very little (3mm), the dirt of formation such as easy lubricated oil in service and coking product thereof, condensed water, metal (or nonmetal) wear particle, air-borne dust stops up, and is difficult to cleaning after the obstruction.
(2) poor reliability: the easy corrosion in the junction surface between heat exchanger tube and fin, operation are loosening easily, poor reliability.
(3) complex structure: rectangular member formula fuse is laterally to put into cooler casing, and it is unreliable that its end adopts the big felt pan of compressibility to make seal operation.
(4) do not meet the design of pressure vessels standard: for fuse is installed, must offer rectangular opening opening greatly on cooler casing, this does not meet the existing design of pressure vessels code requirement of China.
Nineteen ninety-five has been tested a kind of petal type wing shape pipe (being called for short the PF pipe) cooler on the applicant D-100/8-e type air compressor machine.The PF pipe is to process the petal type fin in appearance at copper pipe to form, and can improve 44% than the total heat exchange efficiency of light pipe, has also overcome the drawback of component type fuse simultaneously, and cooling effect has reached designing requirement, and the weight of cooling fuse has reduced 5% than component type.But in process on probation, still find the drawback that the PF pipe is difficult to overcome:
(1) the pipe appearance is dug out the petal type fin, and making originally, tube wall strength weakens greatly.
(2) make the petal type fin and need special equipment, complex process, cost height.
(3) appearance very easily cause expand tube loosening in the work, thereby tube wall and pipe network gouging abrasion is accidents caused both for the petal fin of perk makes that pipe can not be effectively fixing.
Summary of the invention
The utility model provides a kind of shell and tube cooler, and the problem one that it mainly solves is the maintenance clean that makes things convenient for heat exchange element, to guarantee having high heat exchange efficiency in its work; The 2nd, guarantee the bonding strength of cooling tube, thereby improve the reliability of its work.
For achieving the above object, the technical solution adopted in the utility model is: it includes cooling fuse cased, that be made of cooling tube and tube sheet, turbolator is housed in the described cooling tube versatilely, this turbolator by the heat conduction solenoid in the shape of a spiral shape be coiled in the traction mandrel on, one end of this traction mandrel is provided with draw ring, and described shell is externally connected with open portion at an end of described cooling tube at least.
Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:
1, the maintenance clean of heat exchange element is convenient, can prevent and in time solve the blockage problem of heat exchange element, guarantees that it reliably and efficiently works.
2, reliability height: the cooling tube outer surface is a light pipe, can make things convenient for, be connected with tube sheet reliably, is difficult for taking place loosening phenomenon, and structure is firm, is that other three kinds of structures are incomparable.
3, volume is little, in light weight, consumptive material is few: with D-100/8 type air compressor machine charge air cooler is example, and cooling fuse tube bank appearance and size is φ 600 * 540 only, and all littler than the cooling fuse of any same use so far, its contrast situation is listed in the table below:
| Item types | Tube bank appearance and size mm | Number of tubes and specification | Pipe heat exchange area m 2 | Fuse/pipe weight kg | Remarks |
| Common shell and tube | φ600×2500 | 528-φ16×1.5×2500 | 64.7 | 862/792 | Copper pipe |
| Component type | 2-710×400× 400 | 624-φ13×1.5×400 | 9.3 | 622/106 | Steel pipe |
| The PF tubular type | φ460×2506 | 220-φ16×1.5× 2506 | 26.7 | 588/335 | Copper pipe |
| The utility model | φ600×540 | 433-φ19×1.5×540 | 12.9 | 280/204 | Copper pipe contains turbolator |
More than the cooler of several patterns all can reach the required cooling effect of compressor.Can find out from contrast: (1) this patent heat exchanger tube area is 20% of a common shell and tube, is 48% of PF pipe, though component type heat exchanger tube area is also littler, that is because the more result of large tracts of land fin is arranged; (2) this patent fuse gross weight is 32% of a common shell and tube, is 45% of component type, is 48% of PF tubular type; (3) this patent consumption copper material (comprising turbolator) is 61% of PF pipe for 26% of common shell and tube, though component type consumption tubing still less its fin partly more recuperation is many, its processing technology is more complex; (4) relatively being known by tube bank appearance and size, the cylindrical shell volume this patent minimum of tube bank is installed, is 22% of common shell and tube only, for 60% of component type (also being φ 600 cylindrical shells), is 37% of PF tubular type.Little in light weight just because of volume, easy to process, thus promptly used its manufacturing cost of erosion-resisting copper pipe still low than the component type cooler that adopts steel pipe, say nothing of with other two kinds compared.
3, simple in structure.Its structure is to add movable turbolator to constitute in common tubular heat exchanger basically, so structure is simpler, and the turbolator manufacturing does not need special equipment, is easy to make.
4, installation and maintenance are convenient: because simple in structure, volume is little, in light weight, installation and maintenance are convenient many, especially aftercooler is all the more so.
