Abstract
The utility model discloses a spiral flat tube heat exchange tube bundle fixing structure which comprises spiral flat tubes. The spiral flat tube heat exchange tube bundle fixing structure is characterized in that a sleeve tube is arranged on the same positions of the outer wall of each spiral flat tube, and the spiral flat tubes are arranged in the same spiral line direction, and positions of crosspoints of each sleeve tube are fixed with each other so as to form a whole in a welded mode. According to the spiral flat tube heat exchange tube bundle fixing structure, tube bundle supporting between the spiral flat tubes can be guaranteed, the whole tube bundle is a whole, vibration and mutual abrasion between the tube bundles are eliminated, and service life of a heat exchanger is prolonged.
Description
Technical field
The utility model relates to a kind of fixed structure to the heat exchanger with oblate tube bank, mainly is that spiral flat tube integral body mode of tying up in heat exchanger is improved, and can more guarantee the stability of spiral flat tube tube bank.
Background technology
Heat exchanger with oblate is a kind of novel shell-and-tube heat exchanger.It has been one of maximum achievement that the various countries scientific and technical personnel obtain in field of heat exchangers since last century end.Heat exchanger with oblate has the following advantages than the shell-and-tube heat exchanger of traditional bellows tube, bellows, light pipe: pressure drop is little, and heat transfer efficiency is high, less scaling easy cleaning, and shockproof, cost is low etc., so the heat exchanger with oblate application prospect is very extensive.The characteristics of spiral flat tube, the cross section of pipe are oval, pipe vertically in the shape of a spiral, this characteristics of spiral flat tube are so that heat-exchanging tube bundle can't arrange deflection plate.The structure of no baffle plate in this heat exchanger for the manufacturing of heat exchanger with oblate, has been broken the manufacture method of traditional deflection plate fixed support tube bank.The present the most whole binding method of spiral flat tube.This technology utilizes the contact point on each warp surface of spiral flat tube to support between pipe, and the method for tying up at tube bank external application steel band fixes spiral flat tube.But there are a lot of problems in this method for large diameter heat exchanger.At first, rotate spiral flat tube finds the strong point between adjacent several spiral flat tubes relatively more difficult.Again, be not easy to tie up firmly in the tube bank situation how.Unstable at the strong point, tie up the heat exchanger that moves in the unstable situation, it is large vibration to occur, phase mutual friction between the pipe causes tube wall damaged, or the phenomenons such as weld bond cracking between heat exchanger tube such as the tube sheet.The spiral flat tube tube bank can not be changed heat exchanger tube easily through after tying up, so if heat exchanger tube damages, heat exchanger integral body is with regard to unrepairable so.If it is excessive to tie up strength again, can cause distortion for spiral flat tube, not only the contact of the point between the tube and tube is destroyed, also may be excessive because of the pulling-out force of tube bank, the welding of spiral flat tube and tube sheet is destroyed.
Summary of the invention
In view of above-mentioned present situation, the utility model is to tie up not firm defective in order to solve heat exchanger with oblate in tube bank is fixing, and provide a kind of spiral flat tube heat-exchanging tube bundle fixed structure, guaranteed the tube bundle support between the spiral flat tube, make whole restrain into as a whole, interbank vibration and mutually mutual friction have been eliminated, the service life of having improved heat exchanger.
Technical solution of the present utility model is: a kind of spiral flat tube heat-exchanging tube bundle fixed structure comprises spiral flat tube; Wherein, the same position on a plurality of spiral flat tube outer walls that described same hand of helix is arranged arranges sleeve pipe, is welded to one another and is fixed into an integral body at intersect each other a little position of each sleeve pipe.
In this was novel, the shape of described pipe box should be same shape with spiral flat tube, or oval or circular.
The beneficial effects of the utility model are:
1, under the prerequisite of the performance that does not affect spiral flat tube, improved greatly the stability of spiral flat tube tube bank.Make between its tube and tube not only by the rigid connection of tube sheet, also by spiral flat tube being added the rigid connection of the fixing means of pipe box, guarantee heat exchanger tube in running, can not occur again fixing insecure and shake excessive phenomenon.
2, when mounted, be same rotation direction because having guaranteed spiral flat tube and sleeve pipe, after like this sleeve pipe being welded and fixed, the one-piece auger effect of spiral flat tube is fixing, can not change again, has guaranteed the optimum service condition of spiral flat tube.
Description of drawings
Fig. 1 is this novel scheme of installation;
The spiral flat tube tube bank profile of Fig. 2 Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described further.
Spiral flat tube heat-exchanging tube bundle fixed structure as shown in Figure 1 adopts a plurality of spiral flat tubes 2, makes two ends and the welding of the pore on the tube sheet (not providing among the figure) of each spiral flat tube 2.In this is novel, must be by same hand of helix stringing for a plurality of spiral flat tubes 2 of arranging.Consider in the practical application, because the spiral flat tube 2 of installing of arranging has certain length, for avoiding heat exchanger under running status, the phase mutual friction that causes between each pipe appears vibrating, cause the breakage to tube wall, and the same position on each set spiral flat tube 2 outer wall arranges sleeve pipe 1, one by one behind the mounting sleeve 1, intersect each other a little at described each sleeve pipe 1 that 3 position is welded to one another, sleeve pipe 1 is fixed into an integral body forms mutual support.The shape of this novel described pipe box 1 should be same spiral-shaped for what have with spiral flat tube 2.Can guarantee like this coincideing of pipe box 1 and spiral flat tube 2, increase contact-making surface.Limited reliably the vibration of 2 of each spiral flat tubes, the phase mutual friction that produces.The magnitude setting of related sleeve pipe 1 can be decided according to the concrete length of spiral flat tube 2.
In the present embodiment, related pipe box 1 length is generally at 20-50 mm.Avoid the long heat transfer effect that affects.
Further, except shape and the spiral flat tube of above-mentioned mentioned pipe box 1 is the same shape, also adopt oval or circular.
This novel related heat exchanger tube can also be suitable for the heat exchanger tube of other shapes such as bellows tube, bellows, light pipe except selecting spiral flat tube.Utilize equally that pipe box 1 is also applicable to be fixed into an integral body to above-mentioned various heat exchanger tubes and to form mutual support.
Claims (2)
1. a spiral flat tube heat-exchanging tube bundle fixed structure comprises spiral flat tube; It is characterized in that: the same position on a plurality of spiral flat tubes (2) outer wall that described same hand of helix is arranged arranges sleeve pipe (1), is welded to one another and is fixed into an integral body at the intersect each other position of point (3) of each sleeve pipe (1).
2. spiral flat tube heat-exchanging tube bundle fixed structure according to claim 1 is characterized in that: the shape of described pipe box (1) should be same shape with spiral flat tube (2), or oval or circular.
