Description
Technical field
The present invention relates to heat exchange equipment, relate in particular to a kind of high-pressure aluminum plate-fin heat exchanger.
Background technology
Along with China's rapid development of economy, the demand of mesohigh plate fin type radiator is increasing, and range of application is increasingly extensive.Yet at present the bearing capacity of plate fin type radiator can not satisfy under the working condition of high pressure mostly and moves, and the situations such as distortion, leakage that usually have take place, and have all greatly limited popularizing and utilization of aluminum plate-fin heat exchanger.Such as, in existing patent documentation, application number is 200610039927.1, April 26 2006 applying date, notification number is CN1844827, the day for announcing to be the non-seal stainless steel plate-fin heat exchanger invention for Nanjing University of Technology of on October 11st, 2006, patentee, what the present invention relates to is a kind of non-seal stainless steel plate-fin heat exchanger, be widely used in the fields such as petrochemical industry, dynamic power machine, this heat exchanger structure comprises cover plate, dividing plate, fin, stifled circle, takes over; Dividing plate four limits are provided with flanging, and there is the hole, angle at the two ends of dividing plate, and the hole, angle is arranged on the fin, place, hole, angle on fin seals with stifled circle, several dividing plates interconnect and are sealed and fin has constituted heat exchange core body, and the cover plate for sealing of both sides up and down of heat exchange core body is taken over setting on the cover board.This invention is a kind of heat exchanger of high-efficiency compact, and advantages such as good seal performance are compared with traditional fine-type stainless steel plate heat exchanger, and simple in structure, cost significantly descends.But this invents still, and regular meeting has situations such as distortion, leakage to take place, and can not satisfy under the working condition of high pressure and move.
Summary of the invention
The bearing capacity that the present invention is directed to the plate fin type radiator that prior art exists can not satisfy under the working condition of high pressure operation and usually have the problem of distortion, leakage phenomenon generation, provide a kind of simple in structure, radiating efficiency is high, the high-pressure aluminum plate-fin heat exchanger of the dependable performance that can under high pressure use.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of high-pressure aluminum plate-fin heat exchanger, comprise high pressure plate-fin heat radiation fuse, be welded on the end socket cavity on the high pressure plate-fin heat radiation fuse, closure plate and be welded on suction flange and outlet(discharge) flange on the end socket cavity, high pressure plate-fin heat radiation fuse is by dividing plate, inboard fin, outer seal, outside fin, the side plate on inboard strip of paper used for sealing and both sides is formed, the inboard fin of placing between dividing plate and dividing plate, inboard strip of paper used for sealing is formed internal channel, outside fin of placing between dividing plate and dividing plate and outer seal are formed outer tunnel, described internal channel and external passage layered intersection are placed, the thickness of described dividing plate is 1-1.4mm, the thickness of inboard strip of paper used for sealing is 8-12mm, the thickness of described inboard fin is 0.2-0.3mm, the thickness of outside fin is 0.2-0.4mm, described inboard fin is highdensity porous type fin, outside fin is a rippled fin, and the pitch of rippled fin is 2-4mm.Because for the hardboard fin radiator, because pressure-bearing is higher, use specification, shape for dividing plate, fin and strip of paper used for sealing have also proposed requirements at the higher level, suitably increase fin thickness, also can improve the rigidity of whole plate-fin heat radiation fuse, thereby more help increasing the bearing capacity of hardboard fin radiator; Inboard fin is that highdensity porous type fin can increase its heat transfer area, and increase its heat transfer factor as far as possible, and improve heat transfer efficiency, adopt the rippled fin of the suitable amplification of pitch for the outside fin of outer tunnel, can improve the rigidity of whole plate-fin heat radiation fuse, improve the success rate of soldering.The thickness of described dividing plate is 1.2mm, and the thickness of inboard strip of paper used for sealing is 10mm, and the thickness of described inboard fin is 0.25mm, and the thickness of outside fin is 0.3mm, and the pitch of the rippled fin of outside fin is 3mm.This structure more helps increasing the bearing capacity of hardboard fin radiator.Described end socket cavity inner chamber be shaped as semicircle, be provided with porous shape gusset in the end socket cavity.This structure can improve the bearing capacity of end socket greatly, avoided causing the situation of leakage effectively because of the high pressure dilatancy, in addition because high-pressure fluid general flow velocity in radiator is slower, fluid bias current problem is serious, adopts the porous type gusset can alleviate the bias current problem of high-pressure fluid effectively.
As preferably, described end socket cavity inner chamber be shaped as the semicircle arch.This structure can effectively improve the intensity of whole end socket, the defective of effectively having avoided end socket to leak because of compressive deformation;
As preferably, set up 1-2 root outer seal in the middle of the described outer passage, the outer seal thickening 2-4mm that high pressure plate-fin heat radiation fuse is four jiaos.This structure reduces the distortion of high pressure plate-fin heat radiation fuse effectively, disperse the suffered local stress of weld seam between high pressure plate-fin heat radiation fuse bight dividing plate, strip of paper used for sealing and dividing plate, effectively overcome the excessive and defective that drawn back easily by drawing crack, weld seam easily of bight dividing plate stress.
Preferred as the best, set up 1 strip of paper used for sealing in the middle of the described outer passage, the outer seal thickening 3mm that high pressure plate-fin fuse is four jiaos, this structure reduces the distortion of high pressure plate-fin fuse most effectively, disperse the suffered local stress of weld seam between high pressure plate-fin fuse bight dividing plate, strip of paper used for sealing and dividing plate, effectively overcome the excessive and defective that drawn back easily by drawing crack, weld seam easily of bight dividing plate stress.
According to technical scheme of the present invention; provide a kind of simple in structure, radiating efficiency is high, the plate-fin heat exchanger of the dependable performance that can under high pressure use, thereby the bearing capacity that has effectively solved present plate fin type radiator can not satisfy under the working condition of high pressure operation and usually have the difficult problem of situations generations such as distortion, leakage.
