Abstract
The invention discloses a pipe shell heat exchanger connection structure which comprises a shell body, an end plate, a cover end and heat exchange pipes. The end plate is an outer end plate body and an inner end plate body. The outer edge of the inner end plate body and the outer edge of the outer end plate body are bent disc-shaped plates. The bent body of the inner end plate body and the bent body of the outer end plate body form an annular groove matched with the shell. The step hole wall of the outer end plate body is matched with the step hole wall of the end cover. The portions, on the outer side of the inner end plate body and the outer side of the outer end plate body, of the heat exchange pipes are sleeved with inner reinforcing rings and outer reinforcing rings respectively. The pipe shell heat exchanger connection structure has the remarkable advantages of being firm and reliable to connect and long in service life.
Description
Technical field:
The present invention relates to a kind of heat transfer technology, particularly a kind of syndeton of shell-and-tube heat exchanger.
Background technology:
Shell-and-tube heat exchanger is widely used at machinery and vehicular field, because pipe is thin-walled parts, pipe and end plate, housing and adopt soldering connecting structure between end plate and end cap, especially during vehicle travels on severe road surface, under long pitch, weld produces crack, causing medium string chamber heat exchanger failure, is the defect that this heat exchanger is given prominence to.
Summary of the invention:
The object of the invention is to provide a kind of syndeton of a kind of shell-and-tube heat exchanger of the long service life that is connected firmly.
Realizing technical scheme of the present invention is, a kind of syndeton of shell-and-tube heat exchanger, comprise housing, end plate, end cap and heat exchanger tube, it is characterized in that: described end plate is outer end plate and inner end plate, the outer rim of this inside and outside end plate is the dished plate of bending, the bending body of this inside and outside end plate forms the cannelure matched with housing, and the step hole wall of outer end plate and end cap matches, the sheathed inside and outside reinforcing ring of difference on the heat exchanger tube outside inside and outside end plate.
The present invention has the remarkable advantage of firm and reliable connection and long service life compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
With the following Examples the present invention is elaborated, in order to solve the unstable defect of weld seam, adopt both-end plate, i.e. outer end plate 3 and inner end plate 2, and this inside and outside end plate being become from flat board the bumped head that outer rim has bending, the cannelure that the bending formation of inside and outside end plate and housing 1 match, the step hole wall of outer end plate and end cap 4 matches, this inside and outside tip plate configurations increases welds contact area between housing with inside and outside end plate, and welds contact area between outer end plate with end cap.In order to increase the sheathed inside and outside reinforcing ring 6,5 of difference on the outside heat exchanger tube of inside and outside end plate of the bonding area between heat exchanger tube 7 and inside and outside end plate further.Owing to adopting above-mentioned syndeton, be significantly improved through its anti-vibration ability of vibration test.
Claims (1)
1. the syndeton of a shell-and-tube heat exchanger, comprise housing, end plate, end cap and heat exchanger tube, it is characterized in that: described end plate is outer end plate and inner end plate, the outer rim of this inside and outside end plate is the dished plate of bending, the bending body of this inside and outside end plate forms the cannelure matched with housing, the step hole wall of outer end plate and end cap matches, the sheathed inside and outside reinforcing ring of difference on the heat exchanger tube outside inside and outside end plate.
