According to a significant advantage of equipment of the present invention be, without limits for the permission temperature difference between main MEDIA FLOW and the secondary medium stream.
Be contained in this wall or be installed in coefficient heater on this wall by optional the use, the temperature of wall can be increased to the temperature of tube bank.
This equipment preferably should be configured to make the pipe of wall to have predetermined diameter and predetermined mutual edge distance mutually, and like this, in operating process, wall obtains the temperature of restraining basically.
An appropriate configuration according to present device, it is characterized in that, in its end, be installed in the wall or wall on pipe and the pipe of tube bank be placed in the tube sheet, these tube sheets are connected to inlet tube connector or the outlet connector that is used for main MEDIA FLOW, and housing has the inlet or the outlet of the secondary medium stream of being respectively applied in described end.This structure has more advantage, owing to adopt the tube bank shorter can realize needed available heat exchange surface than known device length, so the length of tube of tube bank can be effectively utilized more.
The advantage of just having mentioned especially can be achieved by such configuration device, the inlet or the outlet that promptly are used for secondary medium stream are disposed respectively as housing as inlet or delivery channel around tube bank, and on the approximate width of this inlet or delivery channel, around between the adjacent tubes of the wall of restraining, be provided for the inlet of secondary medium stream or the opening of outlet respectively.
Now, by the exemplary embodiments of configuration, and with reference to the accompanying drawings, under the condition of claim without limits, further set forth the present invention as the equipment of heat exchanger.
In the accompanying drawing:
Fig. 1 represents the generalized section according to heat exchanger of the present invention, and
Fig. 2 represents to cut schematic perspective view open according to the end of heat exchanger of the present invention.
Identical Reference numeral is represented identical parts among the figure.
At first with reference to figure 1, Reference numeral 1 expression is according to heat exchanger of the present invention.
Described heat exchanger 1 has housing 2, containing pipe 3 in this housing 2.The single pipe of tube bank 3 is not shown among the figure.Yet how very clear to those skilled in the art this tube bank 3 constructs, so needn't illustrate in the drawings.
Tube bank 3 has the first end of the jockey 4 that has the inlet that is used for main MEDIA FLOW 6 and has the second end of the jockey 5 of the outlet that is used for described main MEDIA FLOW 6.The entrance and exit of secondary medium stream 7 produces by described jockey 4 and 5 equally, and this appears in the adverse current with respect to main MEDIA FLOW 6 usually.Therefore, the jockey 5 that is provided with at the second end is as the inlet of secondary medium stream 7, and the jockey 4 that is provided with at first end is then as the outlet of secondary medium stream 7.
For this reason, wall 8 preferred disposition have the pipe 9 that is mounted in it or is installed on it, and a part of MEDIA FLOW that supplies to tube bank 3 is through this pipe 9.This can be clear that in the cutaway drawing of the end of heat exchanger shown in Figure 21.
In the structure of wall shown in Figure 28, pipe 9 is contained in the described wall 8.
Advantageously, the pipe 9 of wall 8 disposes predetermined diameter and predetermined mutual edge distance mutually, and like this, in operating process, wall 8 obtains the temperature of tube bank 3 basically.Obviously, pipe 9 diameter and partly definite by the resistance that the described pipe of the medium of the diameter of the pipe of tube bank 3 and the described pipe of flowing through causes to the distance of wall 8.
The end that Fig. 1 illustrates the pipe 9 of wall 8 and restrains 3 pipe is placed on the tube sheet 10,11, and is all the more so among Fig. 2.Described tube sheet is located at the both sides of heat exchanger 1, is connected to the inlet tube connector 12 or the outlet connector 13 that are used for main MEDIA FLOW 6.
