Abstract

A rotatable water-cooled heat transfer plate is provided which increase water cooling capacity by decreasing turbulence of flow and minimizing the resultant pressure drop. This is achieved by forming a spiral configuration wherein incoming fluid passes through alternate spiral channels while outgoing fluid passes through the intermediate channels.

Rotatable Water Cooled Heat Transfer Plate

A rotatable water-cooled heat transfer plate is provided which increase water cooling capacity by decreasing turbulence of flow and minimizing the resultant pressure drop. This is achieved by forming a spiral configuration wherein incoming fluid passes through alternate spiral channels while outgoing fluid passes through the intermediate channels.

As shown in Fig. 1, strip 1 spirals from the center of transfer plate 3 outwardly in double-walled fashion to outer wall 5 of the transfer plate. With the spiral configuration, it can be seen that fluid, such as water, admitted into the plate at the center via port 7 flows, according to the arrows, through alternate channels to outer wall 5, whereupon it is returned by turnabout 9 back through the intermediate channels to the center, whereupon the fluid exits at ports 11.

Fig. 2 shows a side view of the transfer plate. It can be seen that water leaving ports 11 passes through outer tube 15 which surrounds inner tube 19 by which the water is admitted to the system. As is evident, tubes 15 and 19 are positioned concentric to plate 3 to accommodate its rotation. Although the spiral configuration may be fabricated in any of a variety of ways, one simple technique involves employing metal strips fixed into position by angle clips 13 which may be spot welded to base 21. Cover 17 may then be employed to enclose the system.
