An elongated tube for conveying liquid to be cooled is located in the second chamber and is arranged in a convolution. A port is connected to the first chamber for supplying coolant to that chamber, and a flow path extends between the first and second chambers for permitting fluid flow between the first and second chambers. The flow path is a space between the upper edge of the partition and the top end of the vessel, and the upper edge of the partition uniformly distributes coolant over the elongated tube. A port is located in the second chamber for evacuating coolant from the second chamber.Field of SearchMaterial introduced into and removed from body through passage in body inserted meansTreating material introduced into or removed from body orifice, or inserted or removed subcutaneously other than by diffusing through skin Having means for cooling or heating body, treating or collected material or device Helical or spiral coil Conduit coiled within casing Helical conduit means | |
