Heat Spreader With Thermal Conductivity Inversely Proportional To Increasing Heat

Abstract

A heat spreading apparatus has a body defining a void. A fluid positioned within the void distributes heat via a complete thermodynamic cycle. A disruption of the complete thermodynamic cycle is inversely proportional to the magnitude of dynamic body forces, thereby diminishing heat spreading activity by the heat spreading apparatus.

1 . A heat spreading apparatus, comprising:
 a body defining a void; and   a fluid positioned within the void for distributing heat via a complete thermodynamic cycle;   wherein a disruption of the complete thermodynamic cycle is inversely proportional to the magnitude of dynamic body forces, thereby diminishing heat spreading activity by the heat spreading apparatus.   
     
     
         2 . The heat spreading apparatus of  claim 1  wherein the body defines a void with a fluid transport retarding surface geometry to disrupt the thermodynamic cycle, thereby diminishing heat spreading activity by the heat spreading apparatus. 
     
     
         3 . The heat spreading apparatus of  claim 1  wherein the fluid has a figure of merit that diminishes heat transport capacity, thereby diminishing heat spreading activity by the heat spreading apparatus. 
     
     
         4 . The heat spreading apparatus of  claim 1  wherein the body defines a void with a counter-current fluid flow surface geometry to disrupt the thermodynamic cycle of returning condensed fluid, thereby diminishing heat spreading activity by the heat spreading apparatus. 
     
     
         5 . The heat spreading apparatus of  claim 1  wherein the amount of fluid is in excess of the amount of fluid necessary for optimal heat transfer activity, such that excess fluid in an evaporator region of the void improves heat spreading activity and access fluid in a condenser region of the void reduces heat spreading activity. 
     
     
         6 . A heat spreading apparatus, comprising:
 a body defining a void; and   a fluid positioned within the void for distributing heat via a complete thermodynamic cycle;   wherein body forces disrupt the complete thermodynamic cycle, while a component of these body forces provides a disruption threshold, thereby providing minimum heat spreading activity by the heat spreading apparatus.   
     
     
         7 . The heat spreading apparatus of  claim 6  wherein the body defines a void with a fluid transport retarding surface geometry to disrupt the thermodynamic cycle, thereby diminishing heat spreading activity by the heat spreading apparatus. 
     
     
         8 . The heat spreading apparatus of  claim 6  wherein the fluid has a figure of merit that diminishes heat transport capacity, thereby diminishing heat spreading activity by the heat spreading apparatus. 
     
     
         9 . The heat spreading apparatus of  claim 6  wherein the body defines a void with a counter-current fluid flow surface geometry to disrupt the thermodynamic cycle of returning condensed fluid, thereby diminishing heat spreading activity by the heat spreading apparatus. 
     
     
         10 . The heat spreading apparatus of  claim 6  wherein the amount of fluid is in excess of the amount of fluid necessary for optimal heat transfer activity, such that excess fluid in an evaporator region of the void improves heat spreading activity and access fluid in a condenser region of the void reduces heat spreading activity.
