To avoid the need for a pump, the reservoir has a cooling or heating heat exchanger that helically coils around the main reservoir, which cools from the top down or heats from the bottom up, forming a counter current. The reservoir is connected to at least two conduits, one near the cooler top of the reservoir and one near the relatively warmer bottom of the reservoir. The two conduits connect to one another at a distance from the reservoir forming a dispensing passage, thereby allowing fluid to constantly circulate through the dispensing passage due to difference in the specific gravity in the fluid caused by the temperature difference. The elimination of the pump device is especially desirable for weight sensitive environments such as an aircraft.

Abstract: The invention is a heat exchanger transferring heat from a small heat source to a moving fluid. The inherent limitation of such a system is that most of the heat transfer to the fluid occurs only in the immediate vicinity of the heat input even though a large surface area heat transfer structure such as fins or small fluid passages is used to enhance the heat transfer within the heat exchanger. The invention adds a heat pipe inside the heat exchanger enclosure and in contact with the heat transfer structure. The heat pipe spreads the incoming heat over a larger part of the surface area of the heat transfer structure and improves the heat transfer to the cooling fluid by furnishing multiple heat transfer locations without adding extra thermal resistance between the heat source and the fluid flow.
