Envicool 3D-TVC zero-power phase change liquid cooling solution adopts the latest generation of three-dimensional thermodynamic circulation technology, uses the principle of thermosiphon, replaces the capillary structure of the VC plate with a vacuum chamber, and uses gravity to complete the phase change cycle of the working medium, minimizing heat loss. resistance to achieve efficient heat conduction. The integrated three-dimensional aluminum vacuum structure eliminates the traditional copper die-cast heat sink, strengthens natural convection to achieve efficient heat dissipation, and takes into account the goals of strong heat dissipation, small size, and light weight.
