Flat Plate-Type Heat Pipe

Abstract

Provided is a flat plate-type heat pipe formed of a flat pipe having a predetermined through-hole formed therein and a plurality of grooves extending from an inner surface of the through-hole in a longitudinal direction so that, while the interior of the heat pipe is in a vacuum state, heat in the heat pipe is discharged to the exterior due to a phase change of between liquid and gaseous states of working fluid and the working fluid flows by a capillary force produced from the plurality of grooves, whereby it is possible to obtain a strong capillary force and an excellent cooling effect while it is manufactured through a simple process.

1 . A flat plate-type heat pipe including: a flat pipe having a predetermined through-hole formed therein; and a plurality of grooves extending from an inner surface of the through-hole in a longitudinal direction, wherein, while the interior of the heat pipe is in a vacuum state, heat in the heat pipe is discharged to the exterior due to a phase change of between liquid and gaseous states of working fluid, and the working fluid flows by a capillary force produced from the plurality of grooves. 
   
   
       2 . The flat plate-type heat pipe according to  claim 1 , further comprising a separation layer for forming a plurality of flow paths in the through-hole. 
   
   
       3 . The flat plate-type heat pipe according to  claim 1 , wherein each of the plurality of grooves has at least one corner from which the capillary force is produced.
