TEMPERATURE-EXOHANGING APPARATUS.

Specification of Letters Patent.

Patented April 14, I908.

Application filed December 31, 1904. Serial No. 239,063.

Apparatus, of which the following is a specii fication.

One object of the present invention is toprovide a simple, reliable and eflicient apparatus for causing two streams of fluid to exchange their temperatures, or in other words, to extract heat from one and impartit to the other.

Another object of the invention is to insure complete separation of the two streams of fluid under all conditions including such slight leakage as might occur at points where it is necessary to provide the apparatus with parts made detachable for the purpose of cleaning its interior.

Another object of the invention is to eflect close caloric contact as well as complete separation of the two circulating fluids whose temperatures are to be exchanged in such manner as to insure a continually changing relation of position between the circulating fluid streams.

Another object of the invention is to provide for convenient and thorough cleansing of the apparatus.

Another object of the invention is to provide a compact mechanical structure such that its parts can be readily and economically assembled. I

The nature, characteristic features, and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof and in which Figure 1, is a top or plan view with parts broken away illustrating apparatus embodying features of the invention. Fig. 2, is an 'elevational view of the apparatus in Fig. 1,

showin the apparatus with some of the cover plates removed. Fi 3, is a top or plan view of the apparatus Wit the top plate removed. Fig. 4, is a sectional view taken on the line 4-4, of Fig. 3, looking in the direction of the arrows and with the intermediate parts of the apparatus except the part 17 b omitted. Figs. 5 and 6, are sectional views drawn to a reduced scale and taken on the lines 55 and 66 of Fig. 4. Fig. 7 ,isaview drawn to a reduced scale and illustrating in plan a detail, and Fig. 8, is a sectional view illustrating a-modification.

As illustrated in the drawings the enerally rectangular structure is made up 0% a series of adjacent chambers 1, 2, 3, 4, 5, 6, 7, etc. Each chamber has one pair of its opposite examp e, in Fig. 5 the chamber 2, has its sides 8 and 9, normally open, and its sides 10 and 11, closed. The cover plates 12, 13, 14, 15 are removable, and it is of course obvious that when they are removed, certain of the opposite sides of the chambers are open and others are closed, the purpose being to remove these plates when it is desired to clean the ap aratus and to have them in place when t 1e apparatus is in operation.

The construction of the chamber shown in Fig. 6, is substantially the same as that shown in Fig. 5. The pair of op osite sides that are open are in Fig. 6, mar ed 10 and 11, and those that are closed are marked 8 and 9. The chambers shown in Figs. 5 and 6, may be taken to be successive chambers as 2 and 3, of the series, so that the successive chambers are arranged cross-wise in respect to each other with their open ends accessible. For instance, the chambers of even number in the series would have their 'open ends accessible from the sides 10 and 11, of the structure, while the chambers of odd number in the series would have their open 'ends accessible from the sides 8 and 9, of the structure as shown in Fig. 5.

At all sides of the structure there are ports a and b, of which those that are disposed at one pair of the opposite sides of the structure connect alternate chambers. .For example, the chambers 1 and 3, are connected by the port a, shown at the left in Fig. 4, and the chambers 3 and 5, are connected at the right by the port I), and so on throughout the series. ssummg that m Fig. 4, the ports (I and I), are located at the opposite sides, A and B, of the structure, there are exactly similar ports at the other pair of opposite sides C and D, of the structure and they connect the chambers 2, 4, 6, etc. This will be readily understood by reference to Fig.2, which shows at the side A, arrows that 1ndicate the ports which connect the chambers of odd number as 1, 3, etc, and which ports sides 0 en and the other pair closed. For' are shown in Fig. 4.'- In Fig. 2, at the side C,

are arrows which show the ports that con which are fitted with inlet and outlet connections'16 and 16", and 17 and 17 to be presently described in detail, One stream of fluid, for example cold water, enters at 16", reaches the chamber 2, in a manner to be presently described, passes from chamber 2, to chamber 4, at the side C, of the structure. It then passes from chamber4, to chamber 6, at the side I) of the structure. It then passes from the chamber 6, to the eighth chamber in the series and so on throughout all the chambers of even number of the series until finally it arrives at the connection 17. From here it may go, for example, to a sterilizer or to any other suitable piece of apparatus which performs the function of altering its temperature. If it should happen to have gone to a sterilizer, it will return by way of the connection 17 and will circulate through the chambers of odd number in the series in a direction indicated by A-B, in Fig. 4, finally escaping by the connection 16. Thus there are two streams of liquid flowing through separate and distinct channels, one channel extending backwards and forwards through the chambers of odd number in the series in the direction A-B, and the other extending backwards and forwards through the chambers of even number in the series and in the direction C I). In other words, these streams [low cross-wise of each other in adjacent chambers and effect between themselves an exchange of temperature. Each of these streams of course flows along its appropriate chambers and through the ports which connect these chambers, so that the fluid of each stream is constantly disturbed. When the cover plates 12, 13, 14 and 15, are removed, it is obvious that the various channels are accessible, those of even number from both sides C & I), and those ,of

odd number from both sides A and B. The cover plates may be held to place by bolting or otherwise securing them to thestructure and may be fitted on their inner faces with suitable gaskets or packings but if they should leak a little no harm would be done.

- 1f fluid should leak at the righthand end in direction C-D,- and the contrary of this is true.

The structure can be conveniently made in the following manner: 19, Fig. 7, are plates each notched on its adjacent sides as at 20, for the purpose ofproviding the ports which have been referred to. Instead of notching the plates 19, to form the ports, the lattermay comprise recesses 1) formed in the inte rior faces of the cover plates 12, 13, 14 and 15 as is shown in Fig. 8. The plates 19, may be exceedingly thin and constructed from sheet metal and they may be erforated at the corners for the passage of tlie bolts 21, which afford convenient means for assembling the parts of the structure as well as for supportmg them.-

22 and 23, are strips of which one 23, is notched as at 24, to provide the orts already described. T he stri s are s own as provided with openings for t e passage of the- )olts 21. The strips are interposed in pairs between the plates 19 so as to form the chambers which have been described and the pairs of strips are arranged in the respective chainbers in cross-wise relation to the preceding and succeeding pairs so as to leaveopposite sides of the chambers open. The strips are substantially (so-extensive in length with the edges of the plates to which they are adjacent. The strips are soldered to the adj acent plates or aproper joint is otherwise provided. At the top and bottom of the structure one of the strips 25, Fig. 3, is made somewhat wide and is provided with an opening as shown in said figure. This opening is alined with and made a continuation of the opening 16*, in the cover plate so that the opening 16", communicates through the opening in the strip 25, with the chamber 2, whereas the opening 16, communicates with the chamber 1. At the bottom of the structure there is the same arrangement of com aratively wide strip and openings so'that a eseription of the bottom is unnecessary.

. It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details Without departing from the spirit thereof, hence the invention is not limited further than the prior state of the art may require, but

Having thus described the-nature and objects of-my invention, what I claim as new and desire to secure by Letters Patent is:

1. A temperature exchanging device eonsisting of a self-sustaining structure having a tinuous circuitous channels, and means for detachably clam ing the covers to the structure, substantially as described.
