Abstract
The utility model discloses a vibration absorption high efficient heat exchanger. The vibration absorption high efficient heat exchanger is characterized in that a wave node heat exchange tube is symmetrically connected with vibration absorption elements which are made of metallic materials or non-metallic materials at the connection point with a deflection plate on an axial direction; the distance of the wave node of the vibration absorption wave node heat exchange tube is 15 to 30 millimeters, and the wave height of the vibration absorption wave node heat exchange tube is 2 to 5 millimeters. The utility model has the advantages of high heat efficiency, good vibration absorption property, good noise reduction property, high durability, convenient manufacture, convenient installation, convenient maintenance and low cost.
Description
The utility model relates to a kind of heat-exchange device, specifically a kind of vibration damping high-performance heat exchanger.
Heat exchanger is a kind of indispensable heat-exchange device in the industrial production.Common tubular heat exchanger, shortcoming such as because heat exchanger tube is the light straight tube, and it is low to exist heat exchange efficiency, easily stops up, and floor space is big.The waved tube heat exchanger that developed recently gets up have heat exchange efficiency higher, do not stop up, advantage such as volume is little.Vibrate but in use exist between node heat exchanger tube and the deflection plate, cause the fatigue damage of node heat exchanger tube, adverse consequences such as wearing and tearing cracking or cut-out.Its reason is the pitch of the thickness of deflection plate less than the node heat exchanger tube.Solution is to increase deflection plate thickness greater than pitch, though played damping effect, but also correspondingly reduced heat transfer efficiency, tube bank weight strengthens, increased tube bank difficulty and expense in making installation and maintenance, particularly the problems referred to above seem more outstanding in floating head type or U pattern heat exchanger.
In view of existing problem in the above-mentioned prior art, the purpose of this utility model provide a kind of heat exchange efficiency height, vibration damping, durable, make and overhaul vibration damping high-performance heat exchanger easily.
Realize that the technical scheme that the vibration damping high-performance heat exchanger is adopted is: on the basis that does not change the heat exchanger basic principle, performance, structure, parameter to waved tube heat exchanger are further improved, optimize, improve, especially to producing vibration between node heat exchanger tube and the deflection plate, cause the structure of adverse consequences, and the wave pitch of node heat exchanger tube is from having carried out substantial improvement with wave height.Its technical essential is:
The vibration damping high-performance heat exchanger, it comprises front header, upward tube side adapter, upward shell side adapter, housing, deflection plate, rear header, tube side adapter down, following shell side adapter, it is characterized in that vibration damping node heat exchanger tube vertically with deflection plate connecting position place, be connected with vibration-damped component symmetrically, the wave pitch of vibration damping node heat exchanger tube is from being the 15-30 millimeter, and wave height is the 2-5 millimeter.
Vibration-damped component on the vibration damping node heat exchanger tube can be made into the round casing formula, its width greater than wave pitch from, fixed cover is connected on the node.
The also available distinct methods of vibration-damped component is made other various ways.
After above-mentioned technical essential enforcement, the utlity model has following advantage;
1, since the wave pitch of exchange heat pipe from, crest height, and other relevant parameter be optimized, heat exchange efficiency is further improved again, be 3 times of light straight tube.
2, be connected vibration-damped component on the heat exchanger tube node, effectively reduced the vibration of heat exchanger, reduced noise, need not to increase the thickness of deflection plate, solve the fatigue damage of heat exchanger tube, the problems such as cracking, cut-out of wearing and tearing, in the service life of having improved heat exchanger, reduced cost.
3, vibration damping node heat exchange tube structure is reasonable, is convenient to processing and manufacturing, makes heat exchanger integral installation and maintenance convenient.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Fig. 1 is a kind of embodiment general structure schematic diagram of the present utility model.
Fig. 2 is that A portion is the local structural representation that amplifies of vibration damping node heat exchanger tube among Fig. 1.
Referring to Fig. 1, cryogen takes over 2 by last tube side, enters vibration damping node heat exchanger tube 6 through the first half of front header 1.High temperature fluid is taken over 3 by last shell side and is entered housing 4, and along the flow passage that deflection plate 5 constitutes in housing 4, the heat that discharges is given cryogen through 6 conduction of vibration damping node heat exchanger tube.Fluid after the intensification flows into rear header 7, the Lower Half of getting back to front header 1 again through another part heat exchanger tube 6, and by tube side adapter 9 outflows down, high temperature fluid is taken over 8 by following shell side and is flowed out.Again referring to Fig. 2, heat exchanger tube 6 is the pipes that are processed into the protruding crest shape of axis symmetry along caliber successively, the height of crest projection is a wave height 6H2-5 millimeter, distance between two crests is that wave pitch is from 6L 15-30 millimeter, heat exchanger tube 6 vertically with deflection plate 5 connecting position places, be connected with the vibration-damped component 6B that makes symmetrically.Vibration-damped component 6B makes the round casing formula, and its width, is connected on the node with crest swelling method fixed cover from 6L 5-10 millimeter greater than wave pitch, and the distance of two vibration-damped component 6B equals deflection plate 5 spacings.
Vibration-damped component 6B also can be made into multiple version except that the round casing formula, make and be connected with corresponding technology.
