“ Le cose "che si usano da decenni nei pc" non fanno uso di liquidi, è metallo raffreddato ad aria con una ventola „
I dissipatori degli anni 90 forse. Tutti i moderni dissipatori ad heat pipes contengono del liquido dentro, non sono dei "tubetti conduttori di solo metallo" ma sono dei tubetti con dentro del liquido:
“ The most commonly used envelope (and wick)/fluid pairs include:
Copper envelope with water working fluid for electronics cooling. This is by far the most common type of heat pipe.
Copper or steel envelope with refrigerant R134a working fluid for energy recovery in HVAC systems.
Aluminium envelope with ammonia working fluid for spacecraft thermal control.
Superalloy envelope with alkali metal (cesium, potassium, sodium) working fluid for high temperature heat pipes, most commonly used for calibrating primary temperature measurement devices.
Other pairs include stainless steel envelopes with nitrogen, oxygen, neon, hydrogen, or helium working fluids at temperatures below 100 K, copper/methanol heat pipes for electronics cooling when the heat pipe must operate below the water range, aluminium/ethane heat pipes for spacecraft thermal control in environments when ammonia can freeze, and refractory metal envelope/lithium working fluid for high temperature (above 1,050 °C (1,920 °F)) applications „
