Abstract: A heat transfer device is presented and more particularly a beverage cooling assembly comprising: one or more container holders with each having a first and a second wall with a chamber therebetween, the chamber having an inlet and an outlet and otherwise sealed, through which a circulating fluid is pumped from a reservoir, such as an ice chest; a reservoir adapter attached to the drain outlet of the ice chest and to a supply line, or a pump that is attached to the supply line that is attached to the inlet of the one or more containers, the first wall and a second wall forming a double-walled cylinder with a pocket for a beverage container. The circulating fluid is returned from the outlet of one or more container holders through a return line to the reservoir adapter and then connected to a long line placed through the reservoir adapter and then through the drain outlet of the ice chest, returning the circulating fluid to the reservoir away from the drain outlet.
