Abstract
A selected endothermic agent having a heat of reaction is embedded within an absorbent supporting open cell network matrix. The matrix is capable of being shaped into a form retaining body for the controlled transfer of heat by radiation, convection, and conduction.
Claims20
A device for maintaining the temperature of a heated body at an elevated level, comprising a rigid shape retaining shell having an open celled fibrous matrix uniformly filling the interior of said shell, said matrix having a selected polymeric endothermic agent dispersed throughout and retained within said matrix, said endothermic agent having a latent heat of fusion of at least 50 cal/gm at a selected heat of reaction and being capable of the controlled sustained absorption of heat when said device is subjected to a temperature above said heat of reaction and the controlled sustained radiation, conduction and convection of heat out of said device when the device is no longer subjected to a temperature above said heat of reaction and the device is in close proximity to the body whose heat is to be maintained, thereby maintaining the temperature of the body whose heat is to be maintained at an elevated level.
A device for maintaining the temperature of heated material at an elevated level, comprising a housing for the storage and transportation of the heated material, said housing having at least one wall formed as a rigid shape retaining shell in which is uniformly dispersed an open celled network matrix, said wall and matrix being formed of a substance having a temperature reaction above 500.degree. F., a selected endothermic agent dispersed uniformly within and throughout said matrix and having a temperature of reaction below 500.degree. F. and a latent heat of fusion of at least 80 cal/gm so that heat absorption and radiation, conduction and convection to and from said matrix is effected at temperatures at or below said temperature reaction of said endothermic agent without affecting the structure of said housing.
