COOLING DEVICE FOR FLUIDS Original Filed May 28, 1964 United States Patent G l 3,362,186 COOLING DEVICE FOR FLUIDS Albert S. Patterson, 504 W. 112th St., New York, NJK'.k 10025 Continuation of application Ser. No. 370,822, May 28, 1964. This application Mar. 10, 1966, Ser. No. 542,439 9 Claims. (Cl. 62--316) This is a continuation of application Ser. No. 370,822 tiled May 28, 1964, now abandoned.
My present invention relates to the broad held of refrigeration. The knowledge is common that much heat is absorbed in the evaporation of a liquid (approximately 1050 B.t.u. per pound in the case of water). Many have reduced this principle to practice in devious ways. Each instance has been accompanied by certain disadvantages or limitations, however, such as mechanical failure and chemical corrosion, and the capability of cooling only one type of fluid.
By taking increased advantage of the phenomenon of evaporation into air in an improved and unique manner, then, it is the object of this invention to provide cooling means not only less subject to the above hazards but which offers several distinct advantages. One of these is structural versatility and, through a number of variations and embodiments, its benefits of greater economy and eliiciency are extended to several devices, ranging from only a simple form to others more complex in situations of greater demand, each within the scope of its purpose. Specifically included in these operational beneits is the appreciable reduction in water and/or power requirements incidental to the operation of particular heat-extracting apparatuses. Still another advantage is relative ease of manufacture. These and other advantages will become apparent in the following speciiication, illustrated, in part, by the accompanying drawings, in which:
FIGURE 1 is a central vertical sectional view of a iirst embodiment.
FIGURE 2 is an elevational view partly in section of a modication of FIG. 1.
FIGURE 3 is a sectional view of a second embodiment.
FIGURE 3A is a fragmentary section at 3A-3A on FIGURE 3.
FIGURE 4 is a sectional view of a third embodiment.
FIGURE 4A is a fragmentary section at 4A--4A- on FIGURE 4.
FIGURE 5 is a sectional view of a fourth embodiment.
Turning now to FIGURE l, a simplilied illustration of a water-dispensing unit suitable for a drinking fountain in a restaurant, comprising a container 12 having an inlet 16 and an outlet 18, the outlet being controlled by a tap 24. The container 12 is provided with an absorbent layer 20 covering the entire surface of the wall 22. The absorbent material 20 is shaped in a manner to form a small basin 21 just below the outlet of the tap 24. Waste water 26a drawn from outlet 18 falls into basin 21 and spreads through the absorbent material 20 and is there evaporated, thereby absorbing heat from the container 12 and reducing the temperature of the container and later flowing water 26, the subject fluid to be cooled and consumed.
In this embodiment, the container 12 is preferably coneshaped to obtain several operational advantages. The interior decreases in capacity progressively toward the apex, and it is here that waste water 26a first contacts the absorbent layer 20 and will be most thoroughly supplied therewith for evaporation. The ow of contained water 26 is theerfore from a warmer to the colder section. Concomitantly, however, the conical shape assures uniformity of distribution of waste water 26a, with basin 21 at the apex encouraging quick permeation for maximum cooling;
The absorbent layer 20 is preferably comprised of an in- 3,362,186 Patented Jan. 9, 1968 ICC organic substance, such as mineral wool or open-cell plastic sponge, to permit ready evaporation and quick cooling. Functionally, it acts to break up the waste water into minute droplets, thereby further favoring evaporation, yet it holds the liquid in contiguity' with container 12 until evaporation occurs, thus offering maximum etticiency. This feature will assume greater importance in later igures. Moreover, during periods of disuse the absorbent layer 20 may become dry, at which times said layer will serve as a thermal insulator.
To avoid needless repetition, certain parts common to subsequent figures and performing essentially the same function will be given the same reference characters with prefixes coinciding with the ligure number.
In FIGURE 2 the modification differs from FIGURE l principally in that container 212 is elongated and helically convoluted. Layer 220 is held in place by supporting member 230, which may be a plastic screening or other suitable foraminous corrosion-resistant material. Conceived of as a consumer-operated drinking fountain, a customary louvered housing 238 supports a collector pan 228 usual with such units just under outlet 218. Unconsumed waste Water 226:1 falls through openings 229 therein and onto absorbent layer 220. In the event the supply of waste water becomes excessive, lower collector pan 234 carries away excess 226b through drain 236.
In FIGURE 3 the embodiment differs both in configuration and operation. Although container 312 is elongated, the convolution is serpentine. A hollow, arbitrarilyshaped central passage 341 is formed through which air may be forced by blower 340, actuated by driving means 342, since it is known that increasing air volume promotes evaporation. Pairings 350 enhance blower etiiciency. A penetrating evaporative liquid 326a, preferably water, is provided to absorbent layer 320 by mechanical means 346, which includes piping 358 and spray nozzles 329. As in FIGURE 2, the absorbent layer bridges the convolutions so that there is a continuous outer surface with no intervening gaps so that all the liquid 326a is captured and absorbed.
Conceived of as adaptable to such well known closedcircuit industrial services as cooling jacket water, lubricating oil, or the condensing coils of a sizable air conditioning system, means are further provided for automatically adjusting the fluctuations in demand. This may be accomplished in one instance by regulating the output of blower 340 through control means 344, which may include a heat-sensing element 352 disposed in or near inlet 316, and which acts as a speed control for the motor driving means 342 by varying the power input from energy supply 354 through circuit 356. Circuit 360 connects heat-sensing element 352 with motor-driving means 342. In a second instance, control means 348 may include a moisture-sensing element 362, a solenoid 364, a lever 366, a power source 368 and circuitry 363 and 370, whereby the degree of saturation of layer 320 may be regulated. Here, screening 330 may serve protectively.
FIGURE 4 illustrates an instance in which advantage may be taken of existing conditions favorable to the operation of another embodiment of the invention, such as a ventilation duct 438, within which an increased passage of air is normally assured. As shown, a multiplicity of air passages 441 are created by a plurality of longitudinally arranged and interconnected banks of serpentine coils 412, which may represent the condensing coils of an air conditioning unit, accommodated by fairings 450. The advantages of this arrangement, especially as applied to condensing coils, are not restricted to such an installation, however.
The means for providing the penetrating evaporative liquid (not shown) in this embodiment is seen to differ from the preceding in FIGURE 4A. Feeder tubes 458 branch off from means 446 into the spaces between `coil passes of convoluted container 412 and supply evaporative water to absorbent layers 420, which are conveniently rectangular in shape in this instance, through apertures 429.
In FIGURE the principal difference is that absorbent and porous layer or member 520 is transversely arranged in 4the duct 538, through which air is drawn. This can produce an air-washing effect.
Still other modifications and adaptations will occur to those skilled in the arts to which the invention relates. Hence, it should be understood that I do not wish to be limited to the exact details of construction shown and set forth in this specification.
