A therapeutic cooling system used to remove trapped heat from between a person and an object pressed against the person. Such objects would include: beds, chairs and protective clothing such as body armor. A thin bladder encapsulating a liquid placed between the person and heat trapping object absorbs heat produced by the person. Increased heat transferred to the liquid causes it to expand, become less dense and thus more buoyant than the cooler liquid in the bladder. Convection moves heated liquid upwards towards a thermoelectrically driven cooling unit. When the warmed liquid reaches the cooling unit thermoelectric devices pull heat from the liquid and push it in to a heat sink where is it can expelled from the system. The cooled liquid, now denser, flows back down the bladder by gravity.
