A fluid container includes at least one pulsating combustion unit which defines an elongate exhaust passageway between two substantially parallel plates, along with an elongate combustion chamber communicating with the exhaust passageways. Two end caps close the ends of the elongate passageway and the elongate chamber. Inlets are provided for admitting a combustible fuel mixture to the combustion chamber, and spark plugs provide ignition means to ignite the mixture. The unit is disposed in the container in such a way that a major part of each of the plates defining the exhaust passageway is in direct contact with the fluid. By initiating and sustaining pulsating combustion in the combustion chamber, a high-amplitude shockwave passes through the exhaust gases, which effectively “scrubs”away the gaseous, laminar surface film on the plates, thus enhancing heat transfer through the plates.

In combination: means defining a container for a fluid, and at least one pulsating combustion unit, said at least one unit having: (a) an elongate exhaust passageway defined between two substantially parallel plates made of a material and having a thickness which allows a rapid transfer of heat energy from one plate surface to the other, (b) an elongate combustion chamber communicating with said exhaust passageway, (c) end cap means closing the ends of the elongate passageway and the elongate chamber, (d) inlet means for admitting a combustible fuel mixture to the combustion chamber, and (e) ignition means for igniting the fuel mixture, said at least one unit being disposed in the container such that a major portion of each of the plates is in direct contact with the fluid, the combination further including collection means for removing exhaust gases from said exhaust passageway.
