Description
Technical field
The utility model is related to a kind of heat exchanger, specifically a kind of double tube plate heat exchanger.
Background technology
The cooler service life used on import complete set of equipments is very short, and import price of spare parts is expensive, and the delivery cycle is long, existing
There is each part of cooler to expand with heat and contract with cold Stress non-homogeneity, heat exchanger tube is strongly pullled cracking, reduces the service life of cooler.
The content of the invention
The purpose of this utility model is to overcome above-mentioned weak point, so as to provide a kind of double tube plate heat exchanger.This practicality
New is to solve above-mentioned technical problem by following technical proposals：A kind of double tube plate heat exchanger, including：Fixed plate 1, L-shaped side
Frame 2, tube sheet A3, tube sheet B4 and multiple heat exchanger tubes 5；Connected by L-shaped frame 2 between the fixed plate 1 and tube sheet A3；
Multiple pores, one end of the multiple heat exchanger tube 5 are correspondingly arranged on the fixed plate 1, tube sheet A3 and tube sheet B4
It is fixed in fixed plate 1, the other end of the multiple heat exchanger tube 5 is welded on tube sheet B4 through the multiple pores on tube sheet A3
In multiple pores；The tube sheet B4 is provided with oil return box 6 away from the side of tube sheet A3.
Preferably, one end of the L-shaped frame 2 is fixed by welding on four angles of tube sheet A3 sides.
Preferably, coordinated using gap between the multiple pores on the multiple heat exchanger tube 5 and tube sheet A3.
Preferably, the L-shaped frame 2 is angle bar.
Preferably, the multiple heat exchanger tube 5 is stainless steel tube.
The beneficial effects of the utility model：A kind of double tubesheet cooler of the utility model, due to L-shaped frame and heat exchanger tube
Thermal coefficient of expansion is inconsistent, is easily damaged, therefore the different big reinforcement thickness L-shaped frame of the stress that expands with heat and contract with cold is exchanged heat with multiple
Pipe is arranged on different tube sheets, has gap between exchanger tubes and tubesheets tube sheet A, can freely be unfolded, so that heat exchange
Pipe uniform force, solves problem of the prior art, also saves use cost, it is ensured that safety in production.

Fig. 3 is a kind of sectional view of the B-B of double tubesheet cooler of the utility model
In figure：1- fixed plates；2- L-shaped frames；3- tube sheets A；4- tube sheets B；Many heat exchanger tubes of 5-；6- oil return boxes.
Specific embodiment
The following is specific embodiment of the utility model and with reference to accompanying drawing, further is made to the technical solution of the utility model
Description, but the utility model is not limited to these examples.
As shown in Figure 1, Figure 2 and Figure 3, a kind of double tube plate heat exchanger, including：Fixed plate 1, L-shaped frame 2, tube sheet A3, tube sheet
B4 and multiple heat exchanger tubes 5；Connected by L-shaped frame 2 between the fixed plate 1 and tube sheet A3；L-shaped frame ensure that overall knot
The stability of structure, prevents its skew that shakes；
Multiple pores, one end of the multiple heat exchanger tube 5 are correspondingly arranged on the fixed plate 1, tube sheet A3 and tube sheet B4
It is fixed in fixed plate 1, the other end of the multiple heat exchanger tube 5 is welded on tube sheet B4 through the multiple pores on tube sheet A3
In multiple pores；The tube sheet B4 is provided with oil return box 6 away from the side of tube sheet A3；A kind of double tube plate heat exchanger is divided into upper and lower two
Part, upper part heat exchanger tube is oil-feed heat exchanger tube, and oil temperature now can be very high, and heat exchanger tube can expand；Lower part heat exchanger tube is
Oily heat exchanger tube, oil temperature now can very bottom, heat exchanger tube can shrink, by increasing tube sheet A3 on the basis of original so that heat exchange
Pipe uniform force, will not be by drawing crack.
In the present embodiment, it is preferred that one end of the L-shaped frame 2 is fixed by welding in four of tube sheet A3 sides
On angle.
In the present embodiment, it is preferred that matched somebody with somebody using gap between the multiple pores on the multiple heat exchanger tube 5 and tube sheet A3
Close.
In the present embodiment, it is preferred that the L-shaped frame 2 is angle bar.
In the present embodiment, it is preferred that the multiple heat exchanger tube 5 is stainless steel tube.
The foregoing is only preferred embodiment mode of the present utility model, it is impossible to the utility model protection is limited with this
Scope, the change and replacement of any unsubstantiality that those skilled in the art is done on the basis of the utility model are belonged to
The utility model scope required for protection.
