HEATING OR COOLING APPARATUS Specification of Letters Iatent. Application filed July 1, 1907. Serial No. 381,754.

T o all 'whom it may concern:

Be it known that l, JULES HEIZMANN, a subject of the German Emperor, and residing at Strassburg, Alsace, German Empire,

. have invented certain new and useful lmprovements in Heating or Cooling Apparatus, of which the following is a speci'lication.

My invention relates to improvements in devices for heating, drying, superheating,

condensing, cooling or the like.

The object of the invention is to provide a construction in which, for minimum bulk, there is a maximum effective heating or cooling surface presented, this object being secured by providing specially formed chambers for the passage of the fluid to be heated or cooled. Each apparatus may be used as a separate device, or in an assemblage, as in superheaters, coolers, or the like.

My invention is illustrated in the accompanying drawing, in which- Figure l is an elevation of one l'orm olI the apparatus. Fig. 2 is a sectional view, the upper part heilig a section on the line AMB :5 of Fig. l while the lower part shows a modiiication. Fig. 3 is a vertical section through a second modification. Fig. 4 is an elevation of an apparatus having adouble body.

Fig. 5 is a section on the line (l-D ol" Fig. 4l. Fig. 6 is an elevation and part section of a Jfurther modification. Fig. 7 is a section on the line E-F of Fig. 6. .Figs S-l2 illustrate various methods of assembling the apparatuses.

The body a of the apparatus may be cast,

welded, or riveted. ,lts side walls l) are sinuous and together with theV Vfront and back walls c inclose a chamber d having an inlet and an outlet @,f. The walls c are stayed by 'LO means of short pipes g or the like, cast with the body or secured in place in any suitable manner. They may, if desired, be conical (Fig. 2), and constitute passages through the These pipes g may body of the apparatus. be replaced by solid members, as shown in Fig. 3. A

The fluid passing through the body a contacts with the sinuous walls l) and also with the pipes g, so that it is constantly being separated into currents and thoroughly mixed. The direction of motion of the fluid may penetrate the chamber at any desired angle.

The body a is so set up that the heating or cooling medium surrounding it will contact very large.

with the side walls l) and the walls of the pipes g. In this manner the ell'ective heating or cooling surface presented is relatively The V[luid l'lowing through the chamber d is kept in constant motion, in order that all solid portions may be contacted with as often as possible.

Such a device may be placed in any desired position and any number of such devices may be assembled in any suitable manner, whether parallel with each other or in line, as shown for instance in Figs. S, 10 and 11. These ligures are diagrammatical and show respectively in Fig. S, a number of devices constructed as in Fig. l, set side by side 7e the Vlluid llowing alternately upward and downward through adjacent chambers until the end et the series is reached, in Fig. l0 two upper pairsv oll chambers constructed as in Fig. l and a lower chamber constructed as in Fig. +L, the lluid 'passing down through the right hand chambers ol the two pairs, then down and up through the lower chamber, and linally up through the lelt hand chambers of the two pairs and out; and in Fig. .ll Se three series o'lv chambers as in Fig. 1, each series comprising l'our chambers, and the three series beiiig arranged one series above the other, the [luid passing down through the right hand chambers o'l all the series, then up through the adjacent chambers of all the series, then down again through the next line ol chambers, and inally up through the left hand line of chambers of the three series, and out.

The device may have a double body a, such, for instance as shown in Fig. 4. The central partition 71. compels the lluid to flow through the entire apparatus. F 9 illustrates an assemblage ol such double devices, in which the [luid passes alternately up and down through the successive series. l

Figs. (3 and 7 show-another modification il: placed in vertical position and assembled in a row, the connected inlets and outlets e, j, would constitute lcet. The heat radiating or absorbing l'luid medium would contact with the outer walls l) and ass through the passages g and central eye i. The devices might be inclined to one another, such for instance as shown in Fig. 12. The medium would here flow through the angularly arranged spaces 7c and pass through the passages g, as indicated by the arrows.

ln Figs. S to l2 ol the drawing, which, as

hereinbefore stated, are diagrammatical, and which, as will be readily observed, are drawn to a very small scale, no attempt has been made to show the specific construction of each apparatus comprised inthe several arrangements, such gures being intended solely to illustrate the manner in which series of the devices may be arranged to cooperate with each other, and to show how the Huid passing through one body may be caused to pass through others arranged adjacent thereto.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is r` 1. A heating and cooling device comprising two parallel iiat plates, stays connecting them and maintaining them apart forming a space between them, edgeplates of corrugated form secured between the parallel plates and forming boundaries for the inclosed space, and an inlet and outlet for said inclosed space, said stays being arranged in parallelism with the corrugated edge plates and in such relation therewith and with each other as to cause the medium passing through the inclosed space to travel in sinuous paths and to contact with said stays and corrugated edge plates, substantially as and for the purpose specified.

2. A heating and cooling device comprising two parallel flat plates, tubular stays connecting them and maintaining them apart forming a space between them, edge plates of corrugated form secured between the parallel plates and forming boundaries for the inclosed space and an inlet and outlet for said inclosed space, said tubular stays being arranged in parallelism with the corrugated seais@ ledge plates and in such relation therewith and with each other as to cause the medium passing through the inclosed space to travel in sinuous paths and to contact with said stays and corrugated edge plates, substantially as and for the purpose specified.

3. A heating and coohng device comprising two parallel plates, stays connecting them and maintaining them alpart forming a space between them, edge p ates of corrugated orm secured between the pla-tes and forming boundaries for the inclosed space, inlet and outlet pipes side by side communicating with the inclosed space, and a partition between the inlet and outlet pipes secured between the parallel plates and proj ecting into the inclosed space, substantially as and for the purposes specified.

4. A heating and cooling device comprising two parallel plates substantially circular in form, tubular stays connecting them and maintaining them apart forming a space between them, corrugated plates secured between the peripheral edges of the parallel plates forming boundaries for the inclosed space, a radial partition extending into the inclosed space and terminating in the center of the inclosed space, and two substantially parallel passages on opposite sides of the radial partition forming inlet and outlet to the inclosed space, substantially as and for the purposes specified.

In testimony whereof l affix my signature, in presence of two subscribing witnesses.
