165/151 113/118 R 29/1574 A tube and header plate heat exchanger having a 51 Int. Cl. F28b 9/04 header and a header Plate tube Sheet with the [58 Field 61 Search 165/70, 76, 158-161, header having Sides with 8 extending therefrom 165/153 '154, g 149, 151, 285/158, 41 gaging the top and bottom surfaces of the header plate and holding it in position against movement either [56] R f s Cited from side to side or up and down preparatory to per- UNITED STATES PATENTS manently joining the plate and header. 2,168,549 8/1939 Young 165/151 51 Claims, 3 Drawing Figures HEAT EXCHANGER HEADER One of the features of this invention is to provide an improved tube and header heat exchanger wherein portions on the header function to engage the header plate, also identified as a tube sheet, for positioning the plate properly and thus the tubes held thereby with respect to the remainder of the header.
Other features and advantages of the invention will be apparent from the following description of one embodiment as illustrated in the accompanying drawings. Of the drawings:
FIG. 1 is a plan view of a tube and header heat exchanger embodying the invention with portions omitted for clarity of illustration.
FIG. 2 is a side elevational view taken substantially from the right-hand side of FIG. 1.
FIG. 3 is an enlarged fragmentary sectional view taken substantially along line 33 of FIG. 2.
In the embodiment illustrated in the drawings the heat exchanger comprises a header plate mounting in the form of a header 11 having a pair of spaced and parallel sides 12 extending from a flat base 13 at the sides thereof.
Each of the sides 12 has been provided, as illustrated in FIGS. 2 and 3, with lug portion means comprising two sets of lugs with one set including a pair of lugs 14 adjacent the ends of its side 12 as shown in FIG. 2 and the other set of lugs including a single lug 15 positioned about midway between the lugs 14 in the first set. As indicated in FIG. 3 the lugs 14 and 15 in the two sets are struck from the side 12 and extend inwardly of the header 11. These lugs 14 and 15 in the two sets are spaced apart a distance so as to snugly grasp the opposite flat sides of a header plate 16. This header plate retains the spaced tubes indicated at 17 that are adapted to contain one flowing fluid for heat exchange with another fluid surrounding the tubes all in the customary manner.
In the illustrated embodiment fluid flow paths including the tubes 17 are also defined by small header tanks 18, 19 and 20. These tanks are small or miniature tanks each enclosing a small number of the tube ends illustrated at 21 that extend above the base 13. Thus the small header tank 18 which is connected to an inlet pipe 22 encloses the ends of two adjacent tubes 17 for directing fluid from the pipe 22 into and down through the pair of tubes. The intermediate tank 19 encloses the ends of four of the tubes 17 because in this embodiment the fluid flowing in through the inlet pipe 22 is directed in two parallel paths. The end or outlet tank again encloses two of the tubes 17 ends and is itself connected to an outlet pipe 23 for flow of fluid from the heat exchanger. The opposite end (not shown) of the heat exchanger is provided with small header tanks similar to the tanks 18, 19 and 20 for completing the fluid circuit which as stated in the illustrated embodiment is in two parallel paths in which two sets of tubes 17 are connected in series by these tanks.
As can be seen from the above description the improved tube and header heat exchanger of this invention provides a simple, inexpensive yet secure means including the two sets of lugs 14 and 15 for positioning the header plate 16 properly with relation to the header 1 1 and thus the tubes 17 with relation to the header and to the miniature header tanks l8, l9 and 20 mounted on the outer surface of the heat exchanger base 13.
Having described my invention as related to the embodiment shown in the accompanying drawings, it is my intention that the invention be not limited by any of the details of description, unless otherwise specified, but rather be construed broadly within its spirit and scope as set out in the appended claims.
I claim:
1. A heat exchanger header plate and mounting structure comprising: a tube retainer header plate having opposite surfaces; a header plate mounting having a pair of spaced sides; and a plate securing means on said sides comprising cooperating inturned lugs with lugs of each side being widely spaced apart in a direction parallel to said surfaces and spaced apart perpendicularly to said surfaces a distance preselected to cause said lugs to snugly grasp said opposite surfaces of said header plate at preselected widely spaced positions for holding said header plate in said mounting.
2. The plate and mounting structure of claim 1 wherein said lugs are integral with said sides.
3. The plate and mounting structure of claim 1 wherein said header plate mounting comprises a base extending substantially parallel to said header plate, said sides extending from said base at opposite edges thereof.
4. The plate and mounting structure of claim 1 wherein said lugs on each said side are substantially symmetrically located with respect to said side.
5. The plate and mounting structure of claim 1 wherein two lugs on one side are located one each adjacent to the opposite ends of said side and one lug on said side is located substantially midway between said two lugs.
