Heat exchange device and device for receiving heat generation body

Abstract

A heat exchanger of a heat exchange device includes stacked plate members, each including rectification walls that partition the surface into a lane shape. The rectification walls can include straight-line portions extending along a long side from a first end towards a second end and curved portions. The curve portions include arc-like portions bended from the straight-line portions toward the first long side, and first extending portions extending from the first arc-like portions to the first long side. A curved face being curved towards the first long side can be provided on the curved portions.

         5 . The heat exchange device of  claim 4 ,
 wherein the first sealing protrusions have such a shape that a diameter thereof decreases as each one of the protrusions extends from the first plate member towards the second plate member,   wherein the second sealing protrusions have such a shape that a diameter thereof decreases as each one of the protrusions extends from the second plate member towards the third plate member,   wherein the first recessed portions on the first plate member have such a shape that a diameter on the side of the first plate member is larger than that on the side of the second plate member, and   wherein the second recessed portions on the side of the second plate member have such a shape that a diameter on the side of the second plate member is larger than that on the side of the third plate member.   
     
     
         6 . The heat exchange device of  claim 1 ,
 wherein both sides of the second rectification walls of the second plate member coming in close contact with the first rectification walls of the first plate member have such a shape that both the sides are depressed towards the first plate member, and   wherein both sides of the third rectification walls of the third plate member coming in close contact with the second rectification walls of the second plate member have such a shape that both the sides are depressed towards the second plate member.
