ALAN G. BUTT ATTORNEYS United States Patent HEAT EXCHANGER Alan G. Butt, La Crosse, Wis., assignor to The Trane Company, La Crosse, Wis., a corporation of Wisconsin Application March 11, 1957, Serial No. 645,070
Claims. (Cl. 257-445) This invention relates to heat exchangers and particularly to heat exchangers having spaced metallic plates forming passages for the flow of fluids.
Such heat exchangers have had various boundary means for closing the spaces between plates along the edges of the plates to form envelopes for the passage of fluids. It has been a problem with heat exchangers of this type to braze or weld a header to the heat exchanger core.
It has been customary in the prior art to attach the headers to a completed core. With such a procedure it is diflicult to provide a' good seal between the header and the core, and there is danger of heating the core to the extent'that welded or brazed joints in the core are weak ened or even destroyed.
When heat exchangers are put in operation forces are transmitted from the headers to the core. These forces may be due to expansion and contraction, or to the suspension of the heat exchanger. In some cases the heat exchanger is suspended from its headers. When the exterior walls of the core of the heat exchanger are of thin material, they are incapable of withstanding the forces transmitted from the headers.
It is an object of this invention to provide a heat exchanger in which structural members of the core extend outwardly from the walls of the core and are brazed or welded to the headers to provide a header to core joint of high strength and rigidity.
; It is another object of the invention to provide means on the core of the heat exchanger for locating and holding the header on the core during the brazing or welding operation.
It is still another object of the invention to provide interlocking means between the header and the core of a heat exchanger to improve the seal therebetween.
Other objects and advantages of the invention will appear as the specification proceeds to describe the invention with reference to the accompanying drawings in which:
"ice
tangular parting sheets 14 have upwardly extending flanges 16 along their edges except at the headers 10 and 11. A plurality of envelope components in the form of rectangular parting sheets 18 have downwardly extending flanges 20 along their edges except at the headers 10 and 11. The parting sheets 14 and 18 are arranged alternately one above the other in pairs having their flanges 16 and 20 extending toward each other to form envelopes 21. In the envelopes 21, between parting sheets 14 and 18, are longitudinal corrugated fin plates 22 and transverse corrugated fin plates 24. These fin plates 22 and 24, and the parting sheets 14 and 18 form passageways for conducting the fluid in a circuitous path from header 10 to header 11 as shown by the arrows in Fig. 4.
The envelopes 21 are held in spaced relationship by a plurality of spacers in the form of channels 26 which serve to space the parting sheets 14 and 18 which they contact. It should be understood that these channels 26 may be more closely spaced if it should be desired to increase the heat transfer surface area in these passageways and that these spacers 26 may be in the form of corrugated fin plates similar in cross section to fin plates 22.
The envelopes 21 have strips 28 extending between the fin plates 22'and the flanges 16 and 20. The strips 28 also extend between the fin plates 24 and the flanges 16 and 20. As shown in Fig. 4, one strip 28 extends from theheader clip 38 along the side of the core adjacent the discharge header 13, thence along the end of the core and outwardly into header clip 30. Another strip 28 extends from header clip along the side of the core ad jacent to header 12, thence along the end of the core and outwardly into header clip 32. The strip 28 is held against the flanges 16 and 20 by the fin plates 22 and 24.
- Referring to Figures 5 and 6, a plurality of bars 34 extend between the envelopes 21 at the ends of the core of the heat exchanger. One series of bars 34 extend from within header clip 36 along the end of the core and Fig. 1 is a perspective view of the complete heat exchanger of this invention;
Fig. 2 is an end elevational view of the heat exchanger; Fig. 3 is a side elevational view of the heat exchanger; Fig. 4 is a sectional view taken on line 4-4 of Fig. 2; Fig. 5 is a sectional view taken on line 5-5 of Fig. 2; Fig. 6 is an enlarged sectional view taken on line 6-6 of Fig. 4 showing the parts prior to brazing;
Fig. '7 is an enlarged partial view taken on line 7-7 ofkFig. 5 showing the parts prior to brazing.
And Fig. 8 is an enlarged sectional view similar to Fig. 6 showing another modification of this invention prior to brazing.
Referring to the drawings the heat exchanger has a supply header 10 and a discharge header 11 extending from opposite ends of the core of the heat exchanger for conducting a first fluid. A supply header 12 and a discharge header 13 extend from opposite sides of the core of the heat exchanger for conducting a second fluid.
A plurality of envelope components in the form of recinto header clip 38. A second series of bars 34 extend from within header clip 40 along the end of the core and into header clip 42.
A top outside sheet 44 is superimposed on the uppermost parting sheet 18. This top outside sheet 44 has upwardly extending flanges 46 and 48 forming part of headers 10 and 11 respectively and upwardly extending flanges 50 and 52 forming part of headers 12 and 13 respectively.
A bottom sheet 54 is superimposed on the outside of the lowermost parting sheet 14. This bottom sheet 54 has downwardly extending flanges 56 and 58 'forming part of headers 10 and 11 respectively and downwardly extending flanges 60 and 62 forming part of the headers 12 and 13 respectively.
In the modification shown in Fig. 8 channels 64 ex tend along the sides of the heat exchanger in place of the bars 34 of the first form of the invention disclosed in Figs. 1-7. ,In other respects the heat exchanger of the modification of Fig. 8 is constructed the same as the first form of the invention shown in Figures 1-7.
The manner in which the heat exchanger is produced will now be described. The parts are all placed in their proper positions with brazing 'foil or powdered brazing material between the surfaces to be joined. The brazing foil or brazing powder melts at a temperature lower than the melting point of the elements of the heat exchanger. I prefer to use a brazing foil. A sheet of brazing foil is placed between each parting sheet 18 and the fin plates 22 and 24. A second sheet of brazing foil is placed between each parting sheet 14 and the fin plates 22 and 24. These sheets of brazing foil extend along the inside surfaces of the flanges 16 and 20 and outwardly through the gap therebetween. Small spots of adhesive may be used between the sheets of brazing foil and the parting sheets 14 and 18 to prevent movement prior to brazing. Braz- 3. ing foil is also wrapped around the bars Maud the contacting surfaces of the channels 26. A suitable adhesive may be used to hold the foil in place prior to brazing. It should be understood that this adhesive evaporates completely during, the brazing operation. The top and bottom outside sheets 44 and 54 contact the header clips 30, 32, 36, 38, 40, and 42. Adjacent these points of contact additional brazing material is used.
The assembled elements of the heat exchanger are held in place by a jig. The jig and the elements therein arethen placed in a furnace having a reducing atmosphere such as hydrogen. The assembly is heated in the furnace to a temperature suflicient to melt the brazing foil thus joining all the elements of the heat exchanger into a unitary structure.
Although specific embodiments are shown and described itshould be understood that certain changes may be made without departing from the spirit of the invention and I desire to be limited only by the claims.
