Heat sink

Abstract

A heat sink includes a base, a first fin provided on the base and including a first cutout portion, a first heat pipe including a first linear portion and a first curved portion, the first curved portion being provided in the first cutout portion, and a second heat pipe including a second linear portion connected to the first fin with an adhesive having a heat conductivity.

1 . A heat sink comprising:
 a base;   a first fin provided on the base and including a first cutout portion;   a first heat pipe including a first linear portion and a first curved portion, the first curved portion being provided in the first cutout portion; and   a second heat pipe including a second linear portion connected to the first fin with an adhesive having a heat conductivity.   
     
     
         2 . The heat sink according to  claim 1 , wherein the adhesive is made of a solder member. 
     
     
         3 . The heat sink according to  claim 1 , wherein the first curved portion is curved with respect to the first fin. 
     
     
         4 . The heat sink according to  claim 1 , further comprising:
 a second fin provided on the base and including a second cutout portion, wherein   the second heat pipe further includes a second curved portion provided in the second cutout portion, and the first linear portion is connected to the second fin with an adhesive having a heat conductivity.   
     
     
         5 . The heat sink according to  claim 4 , wherein the second curved portion is curved with respect to the second fin. 
     
     
         6 . The heat sink according to  claim 1 , wherein the first fin includes a hole portion in which the second linear portion is inserted. 
     
     
         7 . The heat sink according to  claim 4 , wherein the first linear portion extends from the first curved portion toward the second fin, the second linear portion extends from the second curved portion toward the first fin, and the first curved portion faces the second curved portion. 
     
     
         8 . The heat sink according to  claim 1 , wherein the first cutout portion is inclined with respect to the base. 
     
     
         9 . The heat sink according to  claim 4 , wherein the second cutout portion is inclined with respect to the base. 
     
     
         10 . A heat sink comprising:
 a base;   a plurality of fins provided on the base and including a first fin and a second fin, the first fin including a first cutout portion, the second fin including a second cutout portion;   a first heat pipe including a first curved portion and a first linear portion extending from the first curved portion, the first curved portion being provided in the first cutout portion, the first linear portion being connected to the second fin, and   a second heat pipe including a second curved portion and a second linear portion extending from the second curved portion, the second curved portion being provided in the second cutout portion, the second linear portion being connected to the first fin.
