Gravity loop heat pipe heat sink, condenser, and production methods thereof

A method for producing a gravity loop heat pipe heat sink, wherein the heat sink comprises a condenser and an evaporator connected to each other, and the method comprises a method for producing the condenser comprising:

• squeezing a base material of a condenser to form a condenser substrate and longitudinal channels of the condenser, wherein the longitudinal channels are parallel to and thread through the condenser substrate and configured to condense vapor;
• drilling holes at the two ends of the condenser substrate to form transverse channels of the condenser that are connected to the longitudinal channels, wherein the transverse channels at the two ends respectively support circulation of vapor and liquid that is formed after vapor is condensed;
• and
• sealing ends of the longitudinal channels and ends of the transverse channels according to determined holes on the condenser that are connected to the outside.
