Cooling element

Abstract

The present invention relates to a cooling element ( 1 ) comprising a frame part provided with at least one cooling channel ( 2 ) for supplying a medium that cools down the cooling element through the cooling element. To provide a more efficient cooling element, the frame part comprises a first curved surface ( 3 ) and the frame part is provided with a bending point ( 5 ), at which the frame part may be bent to change the curvature of said first curved surface ( 3 ).

1 . A cooling element comprising
 a frame part provided with at least one cooling channel for supplying a medium that cools down the cooling element through the cooling element, the frame part being manufactured from aluminum by extrusion, whereby at the extrusion stage the frame part is provided with   a first curved surface,   said at least one cooling channel, and   a bending point, at which the frame part may be bent to change the curvature of said first curved surface, whereby said bending point comprises a groove, which extends along the entire length of the frame part and at which the thickness of the frame part is smaller than elsewhere.   
   
   
       2 . A cooling element as claimed in  claim 1 , wherein
 said first curved surface is convex, and   the cooling element is a cooling element of a coil, and said coil is wound around at least the frame part and arranged to come into contact with at least said first convex surface.   
   
   
       3 . A cooling element as claimed in  claim 2 , wherein
 the frame part comprises a second curved surface, which is convex, and   the cooling element is arranged between the different layers of the coil, and said coil comes into contact with both the convex surface and the concave surface.   
   
   
       4 . A cooling element as claimed in  claim 1 , wherein said cooling element is a cooling element of a choke coil. 
   
   
       5 . A cooling element as claimed in  claim 1 , wherein
 said first curved surface is concave, and   the cooling element is a cooling element of a cylindrical object, and the first concave surface of the frame part is arranged against the cylindrical surface of the cylindrical object.   
   
   
       6 . A cooling element as claimed in  claim 5 , wherein said cooling element is a cooling element of a capacitor.
