The thermosiphon is a system of pumping of the fluids (gas or liquid) based on the Dilatation and the Poussée of Archimedes

A thermosiphon is composed of a room of heating of the fluid, of a low entry and a vertical conduit (chimney) positioned in top of this room. The heated fluid rises and leaves the room by the chimney and then aspires the outgoing cold fluid of the low conduit.

In certain cases (minor), the thermosiphon functions contrary, where the room cools instead of heating, which causes to create the contrary effect. The diagram being then turned over, the chimney in bottom creating the aspiration with the descent of the fluid cools. The hot fluid is then aspired.

Can function in closed circuit (majority of the cases where the fluid is liquid being), if there is a loss of heat by the heated fluid. One finds this system in particular on the Insert S servants, of the Cyclomoteur S with liquid cooling…
