Cooling Device

Abstract

A cooling device comprising a rotating part ( 1 ) provided with an internal space ( 3 ) intended for the transport of cooling liquid and provided with external fins ( 4 ) intended for the transport of gas along at least a section of the rotating part. The rotating part is symmetrical in rotation and revolves around an axis of rotation ( 2 ). The rotating part comprises a cooling liquid pump section ( 5 ), a fan section ( 6 ), and between these an intermediate section ( 7 ) arranged around the axis of rotation, where the fan section has a basic shape of a radially extended plate ( 15 ), wherein the flow of cooling liquid enters at the pump section from an object to be cooled, proceeds through the intermediate section and turns back in the vicinity of the periphery ( 17 ) of the fan section, in order to once again pass the intermediate section and then be pumped back to the object by means of the pump section.

       11 . A heat-exchanging device according to claim  1 , in which the plate has a corrugated shape. 
   
   
       12 . A heat-exchanging device according to claim  1 , wherein said blocks or circular section have/has an axially inclined shape in relation to the radial extension of the heat-exchanging device. 
   
   
       13 . A heat-exchanging device according to claim  1 , wherein liquid channels are formed in said blocks or circular section, such that at least a part of said liquid flow can run through the blocks or circular section. 
   
   
       14 . A heat-exchanging device according to claim  5 , wherein the liquid channels are formed as pipes or cavities in the air pervious material having a plurality of changes of direction for enhanced heat transmission. 
   
   
       15 . A heat-exchanging device according to claim  6 , wherein said pipes have a zigzag form extending radially along and transversally to said plate. 
   
   
       16 . A heat-exchanging device according to claim  1 , wherein air channels are arranged in the air pervious material with smooth changes of direction in order to allow any occurring particles of dust to pass.
