Heat absorbing temperature control devices and method

Abstract

The increase of temperature of heat sensitive devices during heat generating conditions is prevented through the absorption of heat, by providing an organic acid, such as formic acid, acetic acid, propionic acid, butyric acid and mixtures thereof, in an amount sufficient to effect the required heat absorption. Where the heat generating conditions are generated by a heat generator, separate and distinct from the heat sensitive device, the organic acid may be supported in a position between the heat sensitive device and the heat generator. Where the heat sensitive device is itself the heat generator, the organic acid is in contact with the heat sensitive device, either directly or indirectly.

What is claimed is:  
     
         1 . An article of manufacture for the prevention of the increase of temperature in heat sensitive devices through the absorption of heat during heat generating conditions comprising 
 bicarbonate salt in an amount sufficient to effect the required heat absorption; and    means for supporting said bicarbonate salt, the physical characteristics of said means for supporting said sodium bicarbonate being defined by the heat absorbing application.    
     
     
         2 . The article of manufacture according to  claim 1 , wherein the bicarbonate salt is selected from the group consisting of Lithium Bicarbonate, Sodium Bicarbonate, Potassium Bicarbonate, Magnesium Bicarbonate, Calcium Bicarbonate, Berylium Bicarbonate, Aluminum Bicarbonate, Ammonium Bicarbonate and the mixtures thereof.  
     
     
         3 . The article of manufacture according to  claim 1 , wherein the means for supporting said bicarbonate salt further comprises a retaining matrix, packaging, encapsulation, microencapsulation, enclosure or structure to form a heat absorbing surface, device or structure.  
     
     
         4 . The article of manufacture according to  claim 1 , wherein the heat sensitive device is embedded within the bicarbonate salt.  
     
     
         5 . The article of manufacture according to  claim 1 , wherein the heat sensitive device is surrounded by the bicarbonate salt.  
     
     
         6 . The article of manufacture according to  claim 1 , wherein the means for supporting said bicarbonate salt is a closed container, within which said bicarbonate salt is located.  
     
     
         7 . The article of manufacture according to  claim 6 , wherein said bicarbonate salt lines the inner wall of the closed container.  
     
     
         8 . The article of manufacture according to  claim 7 , wherein said heat sensitive device is located within and spaced from said bicarbonate salt.  
     
     
         9 . The article of manufacture according to  claim 1 , wherein said bicarbonate salt is adhered to a flexible substrate, said substrate being adaptable to the size and shape of said heat sensitive device.  
     
     
         10 . The article of manufacture according to  claim 1 , wherein the means for supporting said bicarbonate salt is the bicarbonate salt itself.
