Heat exchanger system
First Claim
1. A heat-exchanger system for heat-exchange between a gas and a liquid comprising:
- (a) a base plate;
(b) a plurality of plastic tube coil units tightly packed and mounted on said base plate, each of said coil units comprising a length of plastic tubing wound to form said coil, the windings of said coil units being slightly spaced, said coil units having open ends and a hollow interior and wound to present a frusto-conical profile, said frusto-conical coil unit having a larger base and a smaller base, said base plate having an opening therein aligned with and corresponding to the size and shape of the open end of said larger base of said coil unit adjacent thereto;
(c) closure means covering the open end of said smaller base of said coil unit opposite to that on the base plate;
(d) means in said closure means for causing gas to flow through the interior of said coil unit windings in a direction generally perpendicular to the conical surface of said coil unit; and
(e) separate delivery and return means connected to the ends of said tubes for delivering and withdrawing liquid, respectively, from said coils.

Abstract
There is provided a heat-exchanger system for heat-exchange between a gas such as air and a liquid such as water, comprising at least one heat exchanger unit which unit comprises at least one tube which is wound to form a hollow coil and which is arranged to conduct said liquid, characterized thereby, that said coil is closed or covered at one end; in that the other end of said coil which is open, is placed against a base plate having an opening which is aligned with the coil opening and has a size and shape corresponding to those of the coil opening; and in that the turns of the coil are slightly separated in order to permit the gas to flow perpendicularly across the tube during the passage through the wall of the coil.
