Abstract

The utility model discloses a heat exchanging heater. The heat exchanging heater comprises a container, a tube bundle is arranged in the container, and the tube bundle is in a U shape. The entrance end and the exit end of the U-shaped tube bundle are both fixed on a tube plate, and the tube plate is located in the container and divides the container into a first cavity and a second cavity, wherein the tube bundle is placed in the second cavity. A transverse partition plate is arranged in the first cavity and divides the first cavity into an upper cavity and a lower cavity, wherein the upper cavity is communicated with the entrance end of the tube bundle, and the lower cavity is communicated with the exit end of the tube bundle. A heating medium inlet is arranged on the upper cavity, a heating medium outlet is arranged on the bottom of the lower cavity, and the second cavity is provided with a heated medium inlet and a heated medium outlet. The heat exchanging heater has the advantages of being long in service life.

Description

A kind of heat exchange heater

Technical field

The utility model relates to a kind of heater, relates in particular to a kind of heat exchange heater

Background technology

The heat exchange heater is the equipment with the part heat transferred cold fluid (heated medium) of hot fluid (heat medium).

A kind of heat exchange heater structure of the prior art is that long straight tube bundle is set in container, and the tube bank two ends are fixed in the container, and an end is as the heat medium import, and the other end exports as heat medium.This heat exchange heater structure is simple, the efficiency of heating surface is high.But the heat exchange heater often is in the different temperature condition, and this just causes tube bank to expand with heat and contract with cold, and because the tube bank two ends all are fixed in the container, tube bank can not freely be stretched, thereby makes when tube bank has the temperature difference, produces thermal stress.Therefore, existing this heat exchange heater often uses and damages easily, and service life is shorter.

The utility model content

For this reason, the utility model technical problem to be solved provides a kind of tube bank and when difference variation, can freely stretch, and can not produce the heat exchange heater of thermal stress, with service life of improving the heat exchange heater, overcome the defective that prior art exists.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of heat exchange heater; Comprise container, be provided with tube bank in the said container, it is characterized in that: said tube bank is the tube bank of U type; This U type tube bank entrance point and the port of export all are fixed on the tube sheet; Said tube sheet is arranged in container said container is separated into second cavity of first cavity and ccontaining tube bank, said first cavity with have diaphragm plate with first cavity be divided into restrain epicoele that entrance point is communicated with and with restrain the cavity of resorption that the port of export is communicated with, have the heat medium import on the said epicoele; Have the heat medium outlet under the said cavity of resorption, have the outlet of heated medium import and heated medium on said second cavity.

In the utility model specific embodiment, said tube sheet is positioned at 1/5 place of container, and the length of said tube bank accounts for 4/5 of container.

The outlet of said heated medium import and heated medium lays respectively at the two ends of second cavity, said by very hot medium import be positioned at the top, the heated medium outlet is positioned at the below.

Adopt technique scheme, because the tube bank of U type is adopted in the tube bank of the utility model, the entrance point and the port of export all are fixed on the tube sheet of a direction; Just form free end at U type tube bank crooked position so; Like this, even tube bank has difference variation to cause expanding with heat and contract with cold, free end also can freely stretch; Thereby can eliminate thermal stress, avoid the damage of heat exchange heater.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated:

Fig. 1 is the structural representation of utility model;

Among the figure:

The 100-container, 101-first cavity, 102-second cavity, the import of 103-heated medium; The outlet of 104-heated medium, 200-tube bank, 201-entrance point, the 202-port of export; The 300-tube sheet, 400-lagging, 501-epicoele, 502-cavity of resorption; The import of 503-heat medium, the outlet of 504-heat medium, 600-saddle.

The specific embodiment

As shown in Figure 1, the heat exchange heater of the utility model comprises container 100, tube bank 200 and tube sheet 300.

Wherein, container 100 is oval drum-type container.The bottom of container 100 has two saddles 600.Tube sheet 300 is arranged on 1/5 place in the container 100, container is divided into first cavity 101 and second cavity 102 that is positioned at the right side that is positioned at the left side.Tube bank 200 is the tube bank of U type, and its length is 4/5 of container length, is positioned at second cavity 102, and its entrance point 201 all is fixed on the tube sheet 300 with the port of export 202.

In first cavity 101, also be provided with lagging 400 first cavity 101 is divided into epicoele 501 and cavity of resorption 502.Epicoele 501 is communicated with the entrance point 201 of tube bank 200, has heat medium import 503 on the epicoele 501; Cavity of resorption 502 is communicated with the port of export 202 of tube bank 200, has heat medium outlet 504 on the cavity of resorption 502.

Right ends at second cavity 102 has heated medium import 103 and heated medium outlet 104 respectively, and heated medium import 103 is positioned at the top, and heated medium outlet 104 is positioned at the below.

More than be exactly the heat exchange heater of the utility model, its working method is following:

Heated medium gets into first cavity 102 from heated medium import 103, and finally flows out from heated medium outlet 104; In this process; Heat medium gets into epicoele 501 from heat medium import 503; Entrance point 201 through tube bank 200 gets into the tube bank of U type then; By U type tube bank the heated medium in second cavity 102 is heated, heat medium gets into cavity of resorptions 502 from restraining 200 the port of export 202 more then, finally flows out from heat medium outlet 504.

In the utility model, because the tube bank of U type is adopted in tube bank, the entrance point and the port of export all are fixed on the tube sheet of a direction; Just form free end at U type tube bank crooked position so; Like this, even tube bank has difference variation to cause expanding with heat and contract with cold, free end also can freely stretch; Thereby can eliminate thermal stress, avoid the damage of heat exchange heater.Therefore, the utlity model has the advantage of long service life.

But; Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model, as long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
