LIQUID-COOLER.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed anuary 17 1907- Serial No. 352,730.

To all whom it may concern:

Be it known that I, Anon JENSEN, a citizen of the UnitedLStates, residing at Eureka, in the county of Humboldt and State of California, have invented new and useful Improvements in Liquid-Coolers, of which the'following is a specification.

This invention relates to an improved liquid cooler, especially adapted for cooling milk, cream, beer, or other liquids after having been subjected to pasteuri' zation or other heating process, although several of the novel features thereof render the device advantageous for cooling liquids in general.

In the accompanyingdrawing, Figure 1 is a broken side elevation of my improved cooler; Fig. 2 is a cross section thereof; Fig. 3 is an enlarged sectional view of the bottom of the feed troughs; Fig. 4 is an enlarged sectional view of one of the horizontal cooling pipes; Fig. 5 is an enlarged sectional view of aheader.

Referring to the drawing, 1 indicates posts upon which are supported the rogenerator 2 and the main cooler 3. Said main cooler consistsof the horizontal pipes 4 connected at their ends alternately to headers 5, which headers have therein transverse partitions 6, so that the compartments 42 of said headers form connections upon opposite sides alternately for the horizontal pipes 4. The brine or other cooling liquid enters by the inlet 8 at the end of the lowest horizontal pipe 4, and transverscs said horizontal pipes and the compartments of the headers 5, in a tortuous path, leaving the uppermost horizontal pipe by the outlet 9. The headers 5 are formed of two pieces of sheet metal, the inner piece 10 having a semi-cylindricalfront portion, and its rear edges being bent at right angles to form flanges l1, and around said flanges are bent the edges of a second fiat piece 12 of sheet metal, forming seams at said edges and rendering the same water tight. The cooler 3 is supported upon the posts] by {means of brackets 13 secured to the sheet metal backs 32 of the vertical pipes and having split sleeves 14, by means of which they can be clamped upon said posts adjust ably as to height.

The regcnerator comprises end plates 15 between which is secured a tortuous regenm'ator sheet 16. Upon the upper ends of the end plates are secured the castings 17 which support the trough 18. Said regenerator' is swiveled by means of sockets 21 upon pivot pins 20 extending from sleeves 19 sliding loosely upon the posts 1. It is supported by means of castings 22 secured on the bottom of the regenerator sheet 16, and hav ing recessed lower edges 23, which rest upon the top of the uppermost pipe 4 of; the cooler. With this construction the regencrator can'bc quickly removed by sliding it. upwards from the posts.

The trough 18 is divided into two troughs or compartments by a central partition 24. and the hot milk, cream, or other liquid which has been pasteurized is fed into the compartment 25, shown on the right in Figs. 2

sheet and by reason of the tenuity of the film adhering to the sheet on the underside thereof, and thus it traverses the whole extent of the sheet. In doing so it gives up a considerable part of its heat to the plate, and this heat is utilized to warm the liquid which it is desired to subject to the process of pasteurization or the like. This'cool liquid is supplied to the other compartment 28, that on the left in Fig. 3, and falls through similar apertures 26 at the bottom thereof on to the other side of the regenerating sheet 16, and traverses the whole of said other side in like manner as did the hot liquid, then passing into a trough 36 formed at the bottom of the regenerating sheet, and being discharged therefrom by an outlet 30. Bymeans of this device, not onlyisthe heat of the liquid that has been pasteurized or otherwise heated utilized to warm the liquid that is to be subjected to the same process and thus economizes heat in this way, but the cold liquid abstracts the heat from the already pasteurized liquid, and serves to partly cool the same. This partly cooled liquid, upon arriving at the bottom of the regcnerator, flows on to a lip 31 depending from the lowest surface thereof and drops therefrom on to the middle of the uppermost horizontal pipe, and flows down on both sides of said pipe on to the next horizontal pipe. The horizontal pipes are each formed with a depending lip 32 shown in detail in Fig. 4, said lip being formed by seaming one edge of the sheet metal around the other. This lip extends to close proximity to the top of the horizontal cooling pipe immediately below it, so that the liquid passes from the lip to said pipe without splashing. But for said lip, the particles of liquid would tend to collect in globules before dropping, which globules in dropping would splash, thus preventing the distribution of the liquid in the thin film which'is so necessary for the rapid cooling thereof. Moreover, these lips increase the extent of the cooling surface, and render the apparatus more efficient for its size. The cool liquid flows off by the pipe 33.

The main cooler is supported upon the posts adjustably because it is intended to be used in combination with a centrifugal pasteurizer, which receives the liquid at the bottom, and by centrifugal force causes it to be discharged at a point as high as the top of the cooler. It is therefore important to be able to adjust the height of the cooler sd that the liquid can be taken in the above the lower portion, the upper portion is also adjusted .secured to the posts and supported on the main cooler, said regenerator being constructed to receive hot and cold liquids and to conduct the partly cooled hot liquid to the main cooler, substantially as described.

2. In a liquid cooler, in combination with posts, a main cooler supported on said posts, and a regenerator slidably secured to the posts and supported on the main cooler, said regenerator comprising two compartments adapted to receive respectively hot and cold liquids, each compartment having at regular intervals in the bottom thereof apertures formed in the bottom of depressions and a tortuous regenerator sheet on to opposite sides of which the liquid falls and on which they travel, substantiallvas described.

3. In a liquid cooler, in combination with posts, a main cooler supported on said posts, and a regenerator slidahly' secured to the posts and supported on the main cooler, said regenerator comprisingtwo compartments adapted to receive respectively hot and cold li'quids, each compartment having at regular intervals in the bottom thereof apertures formed in the .bottom of depressions and a regenerating element having an extended area on to opposite sides of which said element hot and cold liquids pass, and constructed to deliver the hot liquid to the' main cooler, substantially as described.

4. In a liquid cooler; in combinationwith posts, a main cooler supportcd on said posts, and a regenerator slidahly secured to the posts and supported on the main cooler, said regenerator comprising two compartments adapted to receive respectively hot and cold liquids, each compartment having at regutar intervals in the bottom thereof apertures formed in the bottom of depressions and a-regenerati ng element having an extended area on to opposite sides of which said element hot and .cold liquids pass, and having a lip depending from the lowest portion thereof, and extending into close proximity with the main cooler to deliver the hot liquid thereto without splashing, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
