Claim:
A temperature regulating system comprising: a tank comprising: a bottom wall; a side wall comprising a first end opposite a second end, the first end extending from the bottom wall; a top wall extending from the second end of the side wall; and flexible material secured over and spaced from the side wall establishing an empty space region substantially surrounding the side wall; and a baffle system positioned in the empty space region and dividing the empty space region into a fluid pathway that is configured to direct a fluid around the tank in a first direction and around the tank in a second direction opposite to the first direction; and wherein the baffle system comprises a planar, elongated structure having opposite first and second side edges, an entirety of the length of the first side edge contacting an inner surface of the flexible material and an entirety of the length of the second side edge contacting the side wall of the tank, the baffle system extending helically along the height of the tank to allow a fluid to contact substantially an entirety of the side wall of the tank, a vertical cross-section of the baffle system has the baffle system curving downwardly as the planar, elongated structure of the baffle system extends from the flexible material to the tank.
