Application December 12, 1941, Serial No. 791,408
6 Claims. 1
This invention relates to heat exchangers and more particularly to heat exchangers which are suitable for use as radiators for internal combustion engines.
One object of the invention is to provide a. heat exchanger which is simple and inexpensive to manufacture and assemble and which has a high heat transfer capacity.
Another object of the invention is to provide a sectional header construction which gives increased strength and which allows the tubes, fins, and headers to be readily assembled and held in place for the weld ng operation.
Another object of the invention is to provide a fin construction which gives increased strength to the unit and also a higher rate of heat transfer.
Further objects of the invention will become apparent from the following detailed description taken in connection with the drawings which form a part of this application, and in which Fig. 1 is a front elevation of my improved radiator partly in section taken on lines I-l of Fig. 2.
Fig. 2 is a top plan view partly in section.
Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2 with the fin sheet removed.
Fig. 4 is a perspective view of a tube and its header channels showing one step in the assembly of the radiator.
Fig. 5 is a sectional view showing a modification of my invention.
Fig. 6 is a sectional view showing another modification of my invention.
Fig. 7 is a sectional view showing still another modification of my invention.
Fig. 8 is a view looking at the side of the fin sheet.
Fig. 9 is a sectional view of the fin sheet taken on the line 39 of Fig. 8.
Referring to the drawings, the radiator of my invention has an upper tank I 0 and a lower tank 12. Each tank has a header which consists of a plurality of channels 14 which in the finished.
radiator are welded or brazed together along the outside surfaces of their flanges It. The tanks are welded to the ends of the headers by having the ends of the tanks overlap the outside flange of the end channels. The sides of the tanks are through tubes 2. The tubes are formed of sheet material with an overlapping seam 24. The tubes 22 have two longitudinal corrugations 26 which are deep enough so that the material of the two sides may be in contact for welding along the corrugation. It should be understood that one corrugation or a number exceeding two could be used if desired. The tubes each have transverse outwardly extending beads 28 a, short distance from each of their ends, and they have outwardly flared ends 29.
Figs. 5, 6, and 'I show three modifications of the preferred embodiment of my invention which is shown in Figs. 1-4. In the form of Fig.5 the channels 34 correspond .to the channels ll of Figs. 1-4, but in this form the flanges 33 of the tube receiving hole extend in the same direction as the flanges 35 of the channel. Fig. 6 shows the channels 36 of the header with the flanges 31 of the channel and the flange 39 of the hole extending in the same direction and away from the header.
Fig. 7 shows the channels 38 of the header with the flanges 4| of the channels extending away from the header and the flange of the holes 43 extending the opposite direction.
Fin sheets 30 extend between the tubes and they are preferably welded or brazed to the tubes. Fin sheets 32 are welded to the outside surface of the tubes at each end of the radiator.
The thickness of the material of the fin sheets has been exaggerated in Fig. 1 for purpose of illustration, but in actual practice the thickness would be approximately between four and thirty thousandths of an inch, but preferably about six thousandths of an inch. The fins may be straight in the direction of air flow, however I prefer to use a fin which is corrugated in the direction of air flow as is shown in Figs. 8 and 9.
The actual dimensions for the fin sheet will be given in order to show the relative size and shape of the fin, but it shouldbe understood that these dimensions can be varied considerably without departing from the spirit and scope of my infastened to the headers by means of channels l8.
Each of the channels I has a flanged, round ended slot 20 struck from the web. In the preferred embodiment shown in Figs. 1-3 the flanges 2| of the slot 20 extend in the opposite direction from the flanges 16 of the channel. Heat exchange medium fiows from tank I0 to tank I2 vention. The height "11. of the corrugations which extend generally in the direction .of air fiow is approximately .421 inch, but this dimension can be varied considerably according to the particular application. My preferred spacing of the fins is such that there are approximately twelve fins to the inch, but as few as six per inch or as many as 14 per inch would be practical for .some applications. The shape of the peaks of these corrugations is such that n is about .040 inch and r: is .017 inch. Thefln has a fiat porlion making an angle or, of 45", because if this were not done the material would have a tendency to tear at this point because it would have a sharp convex curvature in two planes at right angles to each other. The corrugations which extend transversely to the direction of air flow have a shape such that the distance 1) between the troughs and the peaks is .1375 inch. The angle a is then made 24--21'-26.2" in order that the points!!! may be opposite the points 42.
The radius 1' should be small in order to create turbulence in the air to increase the rate of heat transfer. I prefer that the radius 1' should be about .020 inch. It should be understood that the radius 1' could be increased slightly without seriously reducing the heat transfer capacity. The dimension n and the angle a could also be varied, but I prefer that they should be such that the points 40 are opposite the points 62. The portions of the fins between the troughs and peaks are substantially straight. as shown except where they are joined on radius 1'. It should be understood that clearance between the dies is necessary and that the dimensions of the finished fin sheet may vary slightly from those specified above.
In assembly of the heat exchanger, a channelll is slipped on each end of a tube 22 with the end of the tube extending through the slot 20 in the channel and with the edge of the flange of the slot 20 resting against the head 28 on the tube. The ends of the tubes are then flanged outwardly to lock the channels on the tube. In this way the beads 28 accurately determine the spacing of the channels Id of the headers. The fin sheet 30 may then be placed on the tube be tween the channels i4, and another tube and channel assembly added. Fin sheets and tube and channels assemblies are then added to the stack in the above described manner until the desired size of heat exchanger has been assembled.
Pressure is then applied to the top and bottom of the stack so that the peaks of the longitudinal corrugations of the fins are deformed slightly into good contact with the tubes, and the flanges of the channels are pressed against each other for welding.
My preferred method of welding the parts into an integral whole is to use, for the parts, material which has a thin coating of lower melting ma terial on its surface so that when the assembly is heated to the melting point of the surface material, the parts are welded together without melting the base material of the parts. The
welding coating may be on only one surface of.
the two surfaces which are to be welded.
While I have described the foregoing preferred embodiments of my invention, I contemplate that many changes may be made without departing from the scope or spirit of my invention, and I desire to be limited only by the claims.
