HEAT EXCHANGE APPARATUS I Filed Feb. 9, 1937 2 Sheets-Sheet 2 INVENTOR JOHN CRON I N HERSEV ATTORNEMS Patented Jan. 24, 1939 UNITED STATES PATENT OFFIQE HEAT EXCHANGE APPARATUS John-Cronin Hersey, Welwyn Garden City, England Claims.
This invention relates to heat-exchange apparatus of the type comprising a plurality of chambers nested one within the other and arranged to be inter-communicating at points alternately at 5 opposite ends of the chambers, heating means being located within the chambers so as to-lie in the path of fluid flowing through one chamber to the next and there being means for feeding and withdrawing fluid so that it may pass through some or all of the chambers successively. In this type of heat exchanger the nested chambers are formed by cylindrical partitions arranged so as to be substantially coaxial, whereby fluid introduced into the apparatus may follow a sinuous path travelling through one chamber constituted by the cylindrical space located between adjacent cylindrical partitions to the next chamber.
With heat exchange apparatus of this type it is found that difllculty is experienced in repairing the heating elements which are usually the parts of the apparatus liable to deterioration, such difiiculties arising through inaccessibility of the heating means. It is a primary object of the invention to overcome this difliculty.
In accordance with the invention there is provided a heat-exchange apparatus of the type referred to, wherein the heating'means is removably located in one or more casings, the (or each) such casing totally enclosing the associated heating means except for one end of the casing which forms the mouth of the same, and wherein the end wall of the apparatus on which'a casing is supported is formed in a plurality of parts which are united by being connected removably around the margins of the mouth of the casing (or mouths of the casings) as the case may be, whereby such end wall is effectively continuous and the heating element or elements may be readily withdrawn from the casing or casings, or the latter removed at will by disassembling the end wall.
In order that the said invention may be clearly understood and readily carried into effect, the same will now be described more fully with reference to the accompanying drawings, in which:
Figure 1 is a longitudinal section through a heat exchange apparatus in accordance with the invention;
Figure 2 is a sectional view of a detail of the apparatus shown in Figure 1;
Figure 3 is a plan view of the apparatus shown in Figure 1, and
Figure 4 is a sectional View on the line IV-IV of Figure l as seen in the direction indicated by the arrows.
The illustrated apparatus is intended more particularly for the heating of water. There is a base or end plate I, and a multi-part top plate 2. Both the plates are of circular shape, and are joined by a cylindrical connecting member 3. The member 3 is internally screw-threaded at both ends to co-operate with external screw-threading formed upon the plates l and 2. In order to afford a liquid-tight joint between the member 3 and the plates 1 and 2, washers 4 are interposed. The plate 3 has a antral aperture into which there is screwed a feed nozzle 5. A sectional view through the nozzle 5 is shown in Figure 2, and it will be seen that feed openings 6 are formed in the nozzle. As shown in Figure l, the openings 6 are inclined upwardly from the hollow centre of the feed nozale to the exterior thereof, and from Figure 2 it can be seen that the openings are set tangentially to the nozzle. The feed nozzle 5 is locked in posi tion on the plate I by means of a lock nut l and in interposed washer 8. The threaded lower portion 5A of the nozzle then serves as one part of a connecting union for a feed pipe.
Around the feed nozzle 5, there is carried by the plate I a cylindrical partition 9. The partition 9 is of such length that there is a small clearance between its upper end and the interior adjacent wall of the upper end plate 2. Aconcentric partition I0 is also carried by the plate I, there being further partitions of a like kind, II and 12. All the concentric partitions carried by the end plate I terminate short of the end plate 2. The end plate 2 also carries two cylindrical and concentrically positioned partitions l3 and IA. The end plate 2 is formed with a central aperture which is opened to a larger diameter at the exterior side of the plate. The portion of the aperture of larger diameter is internally screwthreaded as at IE, to receive an externally screw threaded sleeve H5. The sleeve I6 has grooves I! cut across its top face for the reception of a turn-key. A cylindrical shell or casing l8 formed with a flanged mouth [9, is held in the central aperture of the plate 2, there being a suitable packing piece located between the shoulder of the plate and the flanged mouth I9 of the casing H3. The lower end of the cylindrical casing I8 is closed, but at its upper end it is left free for the insertion of a heating element.
The vmulti-part upper end plate 2 is made in two distinct parts 2A and 2B. The part 213 is formed as an inverted T-section annulus, whilst the part made as a substantially 8-section annulus, the two parts being connected one to the other by means of a cylindrical hollow shell.2 I.
their top and bottom ends.
The shell 2| fits between the partitions l and I carried by the lower end plate I, and has a flanged mouth 22 seated upon packing washers 23. A nut member 24 of annular form is arranged to engage screw-threading upon the part 2A and to hold one side of the flanged mouth of the shell upon its seating in the member 2A. A further annular nut member 25 engages screw-threading upon the part 2B of the top end plate, and presses the other side of the flanged mouth of the shell 2| upon its seating. The upper surfaces of both the nut members 24 and 25 are formed with grooves 26 and 21 to allow a turn-key to be brought into operation on the nuts for the purpose of tightening or withdrawing them.
As may be seen from Figure 4 of the drawings, the external connecting wall 3 is formed at one point with a portion of increased thickness, such portion having an axial bore 28. The bore 28 is shouldered back near its outer end and is internally screw-threaded to receive part of a connecting union 29. The bore 28 opens into the chamber formed between the outer wall 3 and the partition |2.
When the apparatus is in use for the purpose of heating water, electric or other heating means are disposed within the cylindrical casing l8 and the shell 2|. The shell 2| may, for example, receive an electrical heating element made in two semi-cylindrical parts, whilst the casing |8 may receive a rod type heating element. The water inlet pipe is connected at 5A and water issues through the apertures 6, the arrangement and formation of the apertures as described, being such that the water swirls around in the space between the partition 9 and the cylindrical casing I8. The water rises in such space whilst being in contact with the heating surface of the casing i8. At the top of the partition 9 the water escapes downwardly through the space between the partition 9 and the partition l3, and then rises through the space between the partition I3 and the partition I0 to begin a downflow movement in the space between said partition Ill and the interior wall of the shell 2|. The wall of the shell2| is heated so that the water rises in temperature in flowing past this surface; The water flows be,- neath the shell 2| at its lower end, and then rises between the outside wall of the shell and the partition H. The water finally escapes by rising over the top of the partition ll, travelling down the space between said partition I and the .next partition l4, rising upwardly between the partition l4 and the partition I2 and lastly, travelling downwardly between the partition l2 and the exterior wall 3 to the outlet channel 28. It will thus be understood that the partitions 9|4 and the shell 2| form chambers nested one within the other and intercommunicating alternately at The water in flowing from one chamber to the next thus has to follow a sinuous path and to flow past the heating means. It is important that the water should follow the sinuous path indicated even when not directly in contact with the shell 2| or the casing I8. This is true for the reason that with the design of the apparatus described, a high tempera ture will normally be reached at the centre of the apparatus. It is, as far as possible, desirable that there should be a fairly even fall in temperature from the centre of the apparatus toward the outside cylindrical walls thereof in order that no considerable amount of heat shall be lost in radiation and, as far as possible, all heat absorbed by the water flowing through the apparatus. The
partitions 9, |3 and I0 become, to a certain extent, heated due to conduction through the end walls of the apparatus and, therefore, the sinuous path that has to be followed by the water in flowing between such partitions results in a gain in thermal efllciency, due to the taking up of that heat which escapes by conduction from the centre of the apparatus towards the peripheral walls thereof. The partitions I, I4 and I2, perform a similar function and again tend 'to increase thermal eiflciency.
In order to effect a maximum heat transfer, the external and internal surfaces of the casing l8 and the shell 2|, are preferably mat and blackanodized when such casing and shell are made from aluminium or its alloys. Furthermore all the surfaces of the partitions are preferably mat and anodized, although not necessarily black-anodized, if such partitions are also 'of aluminium or its alloys.
7 It will be clear that the apparatus described above may be used for the heating of all fluids whether gaseous or liquid, and that if desired the apparatus may be used for the cooling of fluids, merely by the substitution of cooling media in place of the heating elements in the casing l8 and. the cylindrical shell 2|. For this reason the expression heat-exchanging means has been used in the appended claims to include both heating and cooling means. The apparatus described above also lends itself to an arrangement for vaporizing or atomizing liquids, or for the carburation of liquid fuels. Thus air might be introduced at the inlet side of the apparatus, such air passing the casing I8 which in this instance has a heating element arranged within it. The heated air passing through the intermediate passages before contact with the shell 2| may be arranged to encounter a flow of petrol orlike vaporizable fuel,
the mixture thus formed being further heated by contact with the shell2| which in this instance would also contain a heating element or elements. The outlet from the apparatus then supplies the mixture to an internal combustion engme.
The invention will also be found of value in the pre-heating of fuel for Diesel engines.
The apparatus described above may be modified in its constructional form in order to comply with the requirementsof its use, and furthermore the exterior wall may be lagged to increase the efliciency. The thickness of the partitions may be increased or decreased towards the exterior of the apparatus, and also the spacing between the partitions maybe decreased or increased towards the exterior.
The concentric and cylindrical arrangement 01 the partitions and outer wall may be varied without departing from the spirit of the invention. Furthermore, the multipart end plate may be formed in more than two parts and a correspondingly increased number of cylindrical shells employed. Inlet and outlet openings may be disposed at various points in the apparatus, and may be more numerous than indicated in the drawings. In particular it may be desirable to utilize the central aperture having the feed nozzle 5, as the outlet and the bore 28 as the inlet, a swirling inflow being still obtained by virtue of the tangential setting of the bore 28. Any number of heating elements or sources of heat may be employed in casings or shells such as 2| or l8, and the central casing I8 dispensed with if desirable.
It is noteworthy that with the apparatus described above, the heating elements are not directly immersed in the liquid to be treated. The elements may in fact be removed from their protective casings without disturbing the passage of liquid through the apparatus. Further, the protective casings may be removed by disassembling the multi-part end wall of the apparatus.
The term chamber as used herein and in the claims that follow is to be read as meaning the space that is bounded by a partition and an adjacent partition, or a partition and the adjacent exterior walls of the apparatus.
