Heat dissipating assembly

Abstract

A heat dissipating assembly includes a substrate configured to support at least one heat producing component and a thermally conductive cooling fin extending from the substrate, wherein heat is conducted away from the heat producing component.

         1 . A heat dissipating assembly, comprising:
 a substrate configured to support at least one heat producing component;   a thermally conductive cooling fin extending from the substrate; and   a thermally conductive heat pipe conductively coupled to the heat producing component, extending within at least a portion of the cooling fin, and defining a fluid reservoir containing a phase change fluid;   wherein the phase change fluid changes between a liquid and a gas in response to heat conducted from the heat producing component to the heat pipe.   
     
     
         2 . The heat dissipating assembly of  claim 1  further comprising a plurality of cooling fins and a plurality of heat pipes, wherein each heat pipe extends within at least a portion of a respective cooling fin. 
     
     
         3 . The heat dissipating assembly of  claim 2  wherein the plurality of cooling fins are arranged in an array. 
     
     
         4 . The heat dissipating assembly of  claim 1  wherein at least one of the heat pipe or cooling fin is located proximate to the at least one heat producing component. 
     
     
         5 . The heat dissipating assembly of  claim 1  wherein the heat pipe further comprises mechanical fastener configured to couple with the cooling fin. 
     
     
         6 . The heat dissipating assembly of  claim 1  wherein the heat pipe further comprises a screw having a threaded exterior surface, wherein the screw is threaded into the cooling fin and the heat pipe is located within the screw. 
     
     
         7 . The heat dissipating assembly of  claim 6  wherein the screw further comprises an elongated shape having a first end proximate to the substrate and an opposing second end being distal from the substrate. 
     
     
         8 . The heat dissipating assembly of  claim 7  further comprising a thermally conductive material between the threaded exterior surface of the screw and the cooling fin. 
     
     
         9 . The heat dissipating assembly of  claim 1  wherein the heat pipe further comprises an elongated shape having a first end proximate to the substrate and an opposing second end being distal from the substrate. 
     
     
         10 . The heat dissipating assembly of  claim 9  wherein the heat pipe further comprises an inner surface defining the fluid reservoir, wherein the inner surface is configured to provide for capillary action along the elongated shape. 
     
     
         11 . The heat dissipating assembly of  claim 9  wherein the elongated shape of the heat pipe further comprises a cross section configured to negate gravitational effects on the phase change fluid so that the heat pipe operates in any orientation. 
     
     
         12 . The heat dissipating assembly of  claim 1  wherein the cooling fin is configured to remove heat from at least one of the heat pipe or substrate by convection. 
     
     
         13 . The heat dissipating assembly of  claim 12  wherein the cooling fin is exposed to a fluid. 
     
     
         14 . The heat dissipating assembly of  claim 1  wherein the cooling fin further comprises a coating configured to remove heat from at least one of the heat pipe or substrate by radiation. 
     
     
         15 . The heat dissipating assembly of  claim 1  wherein the substrate comprises an alloy configured to match the coefficient of thermal expansion of the at least one heat producing component.
