Apparatus for heating or cooling fluids
First Claim
1. A flexible container means adapted to be received in a frame means having a cross member from which extends a pair of substantially parallel arm elements and in which a liquid may be stored or through which a liquid may be circulated, said container means comprising a pair of walls including two relatively thin, generally flexible sheets of a polymeric material, a top edge, a bottom edge, a centrally located compartment for containing said liquid, an elongated sleeve adjoining each side edge of said compartment, an inlet for introducing said liquid into said compartment and an outlet for withdrawing said liquid from said compartment, each of said sleeves having an inner edge and an outer edge, the straight-line distance between the outer edges of said sleeves being greater along the top edge of the container means than the straight-line distance between the outer edges of said sleeves along the bottom edge of said container means.

- 14. Container means having a top edge, a bottom edge, a pair of opposed side edges, a pair of walls including two relatively thin, generally flexible sheets of a polymeric material, an inlet for introducing a liquid into said container means, an outlet for withdrawing a liquid from said container means, said sheets of material being joined to each other along at least two relatively narrow, internally located lines of attachment to form within said container means at least three primary channels of substantially equal width, said sheets of material being further joined together along at least one additional line of attachment to subdivide at least one of said three primary channels into two secondary channels of reduced width, the number of secondary channels means never being more than the number of primary channels.
