3,335,789 RESILIENT HEAT EXCHANGE DEVICE Walter Raskin, 922 Ave. R, Brooklyn, N.Y. 11223 Filed Oct. 21, 1965, Ser. No. 514,733 1 Claim. (Cl. 165-80) This is a continuation-in-part of application Serial No. 369,944, filed May 25, 1964, and now abandoned.

This invention relates to heat exchange devices and more particularly to a resilient, rigid heat exchange plate which is adapted to be tensioned about containers of various shapes and thus heat or cool the contents thereof.

Generally, the object of the invention is to provide a heat exchange plate of the character indicated, which can be slipped loosely over a drum or other container and then clamped solidly thereabout and locked in the clamped position by double-acting latching means, thus affording excellent conductive heat transfer. The latching means readily springs free of the drum for quick removal therefrom upon release of the latching means.

Another object is to provide a heat exchange device of the character indicated which can be used with steam, water, refrigerants and all the usual heating or cooling fluids, and which possesses suflicient structural strength to permit the device to be used for extreme cooling, such as of the order of --70 F., as well as for extreme heating, such as of the order of +350 F. This means that the device must be able to withstand a negative pressure of about 20 inches or less and a positive pressure of about 100 pounds.

In terms of general inclusion, the invention contemplates a resilient heat exchange plate composed of a pair of superimposed springy metal sheets, preferably made of low carbon steel, at least the outer one of said sheets being embossed to form a continuous flow channel for the heat exchange fluid which extends substantially over the entire area of the plate. The heat exchange plate is pre-shaped to conform generally to the contour of the container to which it is to be applied but with its ends spaced apart, and provided with clamping means effective to draw said ends towards one another and lock the plate in tensioned position about the container and to cause the ends to spread apart and the plate to spring free of the container upon unclamping.

In the accompanying drawing, wherein an illustrative embodiment of the invention is shown,

FIG. 1 is a top plan view of a heating or cooling ring or band constructed according to the invention;

FIG. 2 is an elevational view of the same;

FIG. 3 is an elevational view of the ring or band showing its application to a drum, and

FIG. 4 is a perspective view in section of a part of the ring or band.

Referring to the drawing, 1 generally indicates the heating or cooling panel. In the form shown, the same consists of a pair of superimposed, resilient, metal sheets, indicated respectively at 2 and 3-. The outer sheet 3 is embossed as shown at 4 and is welded to the inner plate 2 along the portions between the embossments. The embossments are arranged to form a continuous flow channel for the coolant or heating fluid. The flow channel extends substantially over the entire area of the plate and comprises a plurality of adjacent, substantially parallel ducts which are connected by transverse ducts. Preferably the transverse ducts constitute a header at each end of the plate which is common to and interconnects the parallel ducts. Nipples 5 and 6 constitute the inlet and outlet for the heat exchange fluid.

The heating or cooling plate, as shown in the drawings, is in the form of a strap, the ends of which are spaced apart as shown at 7, thus providing two separated ends 8 and 9.

The plate is placed in position around the outside of a drum or similar container 10 as shown in FIG. 3 and is tensioned around the same and clamped in solid contact with the outer surface thereof, by means of a toggle latch 11. In the form shown, the toggle includes a threaded stem 12, one end of which is adjustable in the screw threaded lug 13 mounted at one end of the strap. The other end of the stem is connected to one end of a pair of parallel links 14. The other end of the links are pivoted at 15 to an operating handle 16 which in turn is pivoted at 17 to a lug 18 which is mounted at the end of the strap opposite to the lug '13. This arrangement provides a double-acting latch so that by manipulating the handle 16, the ends 8 and 9 of the strap will be drawn towards one another and the strap will thus be tensioned around the drum or other form of container and the inner sheet 2 will be brought into solid contact with the outer surface of the drum. A pair of oppositely positioned handles 20 may be provided in order to facilitate the application of the band to the drum and its removal therefrom.

From the foregoing, the operation and advantages of the described construction will be apparent. The strap when clamped around the drum, is brought into solid contact with the drum, thus affording excellent conductive heat transfer. When fitted in position around the drum, the double-acting latch 11 quickly locks the band in position. When the latch is opened the band springs freely apart for quick removal.

While I have herein particularly described the strap as being applied to the outside of a container, it will be understood that it can also be applied to the inside thereof by expanding it therein to cause it to intimately contact the inner surface of the container. It should also be understood that the strap may be pre-shaped to conform substantially to the contour of various shapes of containers.

It should also be understood that the strap can be applied at any selected location of the container; also a number of these straps can be applied, one above the other on the drum.

Although the invention has been described as applied to one single embodiment, it should be understood that the inventive concept may be expressed in various modifications within the scope of the annexed claim.

Having thus described the invention, what is claimed A resilient heat exchange device adapted to be tensioned snugly about a container, said device comprising a pair of plates of stiff but springy metallic material superposed and connected in fluid tight relationship;

the inner of said plates being preshaped to conform substantially to the contour of the outer wall of the container and, when not under tension, to fit loosely about said container;

the outer of said plates being embossed and welded to the inner plate along the edges and the portions between the embossments to form a continuous flow channel means for the heat exchange fluid extending substantially over the entire area of said plates;

said plates having fluid inlet and outlet means opening into said channel means for supply and removal of said heat exchange fluid;

said plates having the opposed ends thereof spaced apart when said device is fitted loosely about said container; and

clamping means connecting said opposed ends and being effective when operated to draw the ends to- Ward one another, thereby reducing the dimensions of the device and causing it to be tightly contracted around the container With the inner plate in close,

4 i substantially planar, intimate heat exchange relationship With the surface of the container.
