| Cooling is achieved by a patented, non-cycling free-piston Stirling engine coupled to an isothermal thermosiphon which operates without moving parts. |
| If the piping of a thermosiphon resists flow, or excessive heat is applied, the liquid may boil. |
| They depended on forward movement of the car and fans to move enough air through the radiator to provide the temperature differential that caused the thermosiphon circulation. |
| During step 2, the thermosiphon starts to operate and defrosts the air evaporator. |
| This article presents a heat pump for simultaneous heating and cooling in which a thermosiphon forms to defrost the air evaporator. |
| In some cases a thermosiphon may also be less bulky than a normal heat sink and fan. |
