Abstract
The utility model discloses a core of a shell-and-tube heat exchanger. A flanging is added on a tube sheet hole on the basis of the original structure in the design. Due to the design scheme, the soldering joint area with a tube is enlarged, and the strength of the welding seam is enhanced, so that the soldering seam is not easy to fracture. By adopting a composite tube sheet form, the strength at the root of the tube is reinforced, and the stress at the connecting position of the tube and the tube sheet is reduced, so that the tube can better bear the mechanical stress and the thermal stress of the using environment, and further the tube is not easy to fracture; in a word, due to the technical scheme, the defects of the original scheme are solved, and the core can better adapt to the requirement of using reliability.
Description
Technical field
The utility model relates to the connecting mode of a kind of shell-and-tube exchanger tube sheet and pipe, the design of the core body of the heat exchanger of suitable various longer sizes.
Background technology
Existing shell-and-tube exchanger structurally mainly comprises housing and core body two parts.
Core body by two ends tube sheet, cooling tube bundle, middle gusset piece, and fixedly connect and overlap or parts such as flange assemble integral braze-welded forming.
The connecting mode of original tube sheet and pipe is the tube sheet punching, and pipe interts, is matched with in the tubesheet holes, and it is whole that soldering becomes.
There are 2 deficiencies in dependability aspect in the connecting mode of aforementioned tube shell-type exchangers tube sheet and pipe: one, the vibration factor during use often cause the cooling tube fracture, and this fracture is to occur in the tube-to-tube sheet connection junction mostly.Its two, comprehensive functions such as vibrating machine stress during use and thermal stress damage the solder joint of tube sheet and pipe, make the solder joint cracking.
This shows the connecting mode of existing this shell-and-tube exchanger tube sheet and pipe, the requirement of incompatibility dependability.
Summary of the invention
To be solved in the utility model is prior art scheme above shortcomings, aims to provide a kind of core body of more rational shell-and-tube exchanger.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of shell-and-tube exchanger core body, comprise bottom tube sheet, cooling tube bundle, fixedly connect and overlap and gusset piece, described tube sheet is provided with through hole, it is characterized in that part or all of through hole is provided with flange, described cooling tube bundle one end is plugged in the flange through hole, and the other end is connected and fixed and connects cover; Described cooling tube bundle main part is provided with one or more gusset pieces.
Described tube sheet comprises the tube sheet substrate and covers the compound plate that is posted on the substrate, all offers corresponding through hole on described substrate and the compound plate, and the through hole on the compound plate has flange.
The utility model also will provide another kind of shell-and-tube exchanger core body, comprise bottom tube sheet, cooling tube bundle, fixedly connect and overlap and gusset piece, described tube sheet is provided with through hole, it is characterized in that being provided with lining in the part or all of through hole, described cooling tube bundle one end is plugged in the lining, and the other end is connected and fixed and connects cover; Described cooling tube bundle main part is provided with one or more gusset pieces.
Core body of the present invention has increased the flange on the tubesheet holes on the basis of original structure.This design has increased the soldered joint area with pipe, has increased weld strength, makes solder joint not easy to crack.Adopt the clad tubesheet form, strengthened the intensity of pipe root, reduced the stress of tube-to-tube sheet connection connection place, make pipe more can tolerate the mechanical stress and the thermal stress of environment for use, make not easy fracture of pipe; Comprehensively above-mentioned, this technical scheme has effectively solved the deficiency of former scheme, more adapts to the dependability requirement.

The specific embodiment
With reference to Fig. 1, the connecting mode of prior art tube sheet and pipe, its defective front has been described, and does not repeat them here.
With reference to Fig. 2, the connecting mode of tube sheet of the present utility model and pipe carries out: according to the following steps at tube sheet 5 upper punch circular holes; On part or all of tubesheet holes, directly form flange 1; Cooling tube bundle 2 interts, is matched with in the flange hole 8; It is whole that soldering becomes.
With reference to Fig. 3, the another kind of embodiment of the connecting mode of tube sheet of the present utility model and pipe, be that with Fig. 2 embodiment difference described flange 1 forms by the following method: tube sheet 5 comprises substrate 9 and compound plate 7, behind substrate 9 pore-formings, after using compound plate 7 pore-formings again, the hole wall of pore-forming turned up forms flange 1, and is attached to again on the tube sheet 5 in the compound plate mode, and the hole on the described compound plate 7 is corresponding with the hole on the tube sheet 5.
With reference to Fig. 4, another embodiment of the connecting mode of tube sheet of the present utility model and pipe carries out: pore-forming on tube sheet 5 according to the following steps; Lining 6 is set in part or all of punching; Cooling tube bundle 2 interts, is matched with in the lining 6; It is whole that soldering becomes.
Tubesheet holes flange of the present utility model can be at whole pipes as shown in Figure 5 to the protection of pipe, also can be at the protection of local pipe as shown in Figure 6.
The utility model causes hole flanging internal face wrinkling for avoiding the material extruding when the tubesheet holes flange, can be washed into irregularly-shaped hole, and as the zigzag hole, flange as shown in Figure 7 again.
With reference to Fig. 8, shell-and-tube exchanger core body of the present utility model, comprise bottom tube sheet 5, cooling tube bundle 2, fixedly connect and overlap 3 and gusset piece 4, described tube sheet 5 is provided with through hole 8, partly or entirely through hole 8 is provided with flange 1, described cooling tube bundle 2 one ends are plugged in the flange through hole 8, and the other end is connected and fixed and connects cover 3; Described cooling tube bundle 2 main parts are provided with one or more gusset pieces 4.
