Thermosiphon

The thermosiphon effect is based on the difference in density between a warm and a cold fluid . The effect is used to circulate the fluid, which often serves as a heat transport medium, so that energy is saved by eliminating the need for circulation pumps .

• In the thermosiphon system for heat recovery from solar energy, the heated heat transfer fluid circulates.
• With thermosiphon cooling in combustion engines, the cooling water circulates automatically.
• In liquid pumps with a mechanical seal, liquid circulates on the side facing away from the product in order to achieve both cooling of the seal and better "lubrication" between seal and shaft.
• In the heat pipe a fluid is circulated for heat transfer. The same applies to gravity heating .
• Thermosiphon convection brakes are used in heat accumulators in order to prevent undesired heat loss through the thermosiphon effect.
• In thermosiphon (steam boiler) is the heat exchanger elements of steam boilers , increase the de heating surface and improve water circulation in the boiler.
