Title: FLAT PLATE HEAT PIPE, MICRO-CHANNEL HEAT DISSIPATION SYSTEM AND TERMINAL
Abstract:
Disclosed are a flat plate heat pipe (12), a micro-channel heat dissipation system and a terminal. In the flat plate heat pipe (12), an insulating material (42) is provided between a liquid absorption core (43) and an inner surface of a housing (44). The liquid absorption core (43) accesses to a first electric potential, the housing (44) accesses to a second electric potential, and an electric potential difference exists between the first electric potential and the second electric potential. In the micro-channel heat dissipation system, a top plate (611) and a bottom plate (612) are made of a metal material, and an insulating side plate (601) encircles the edge of the two. The top plate (611) accesses to a first electric potential, the bottom plate (612) accesses to a second electric potential, and an electric potential difference exists between the first electric potential and the second electric potential. Using the characteristics of electric field energy enhanced boiling and forced convection heat transfer, the liquid absorption core (43) and the housing (44) in the flat plate heat pipe (12) serving as electrodes, and the top plate (611) and a micro-channel heat transfer face (613) in the micro-channel heat dissipation system serving as electrodes, an electric field is introduced to enhance heat transfer, and by improving the heat exchange coefficient and critical heat flow density, the heat dissipation capacity is greater, thereby improving the heat reliability and heat experience of the flat plate heat pipe (12) and the micro-channel heat dissipation system.
