Abstract

A heat pipe heat sink. The heat pipe heat sink has at least one meandering channel for guiding a cooling medium, with at least two components which delimit the cross-section of the at least one channel. At least the first component is manufactured using a primary shaping process and may have fins arranged parallel to one another for laterally delimiting the cross-section of the at least one channel.

Claims

exact text as granted — not AI-modified
1 - 10 . (canceled) 
     
     
         11 . A heat pipe heat sink, comprising:
 at least one meandering channel configured to guide a cooling medium;   at least two components which delimit a cross-section of the at least one channel, wherein a first component of the at least two components is manufactured using a primary shaping process and has fins arranged parallel to one another for laterally delimiting the cross-section of the at least one channel, and wherein a second component of the at least two components covers the first component at least in a region of the at least one channel as a cover or base.   
     
     
         12 . The heat pipe heat sink according to  claim 11 , wherein the fins have different widths at least over a subportion of their longitudinal extent. 
     
     
         13 . The heat pipe heat sink according to  claim 11 , wherein the fins are rectangular in cross-section and/or trapezoidal in cross-section. 
     
     
         14 . The heat pipe heat sink according to  claim 11 , wherein, at least in some areas, the first component and/or the second component has regions raised in a direction running in a height direction of the fins. 
     
     
         15 . The heat pipe heat sink according to  claim 14 , wherein the fins have different heights. 
     
     
         16 . The heat pipe heat sink according to  claim 11 , wherein the first component and/or the second component has at least one raised portion of increased wall thickness on an outer side facing away from the at least one channel. 
     
     
         17 . The heat pipe heat sink according to  claim 11 , wherein the second component is manufactured using the primary shaping process, and some of the fins are formed on the second component. 
     
     
         18 . The heat pipe heat sink according to  claim 11 , wherein the fins engage in recesses of the first component and/or the second component. 
     
     
         19 . The heat pipe heat sink according to  claim 11 , further comprising a third component configured to deflect a flow of the cooling medium between the fins. 
     
     
         20 . The heat pipe heat sink according to  claim 11 , wherein at least the first component and the second component are connected to one another in a media-tight manner by a material bond at least in edge portions.
