Cooling jacket and electronic device having the same

Abstract

A cooling jacket includes: first and second pipe portions through which a coolant flows; and a main portion connected with side surfaces of the first and second pipe portions, defining, with a single member, a flow path through which the coolant flows, and cooling an object to be cooled.

What is claimed is: 
     
         1 . A cooling jacket, comprising:
 first and second pipe portions through which a coolant flows; and   a main portion connected with side surfaces of the first and second pipe portions, defining, with a single member, a flow path through which the coolant flows, and cooling an object to be cooled,   wherein the main portion comprises
 a first main portion defining, with a single part, a first flow path through which the coolant flows; and 
 a second main portion defining, with a single part, a second flow path through which the coolant flows. 
   
     
     
         2 . The cooling jacket of  claim 1 ,
 wherein the first pipe portion comprises:
 a supplying portion allowing the coolant to flow into the first main portion; and 
 a collecting portion into which the coolant flows from the second main portion, the first main portion is connected with the supplying portion and the second pipe portion, and 
   wherein the second main portion is connected with the second pipe portion and the collecting portion.   
     
     
         3 . The cooling jacket of  claim 1 , wherein the first and second main portions are connected with the first and second pipe portions, and are stacked to each other in a vertical direction.
