Abstract
Abstract This disclosure pertains to a blanket having a plurality of portions of flexible heat pipes sandwiched between the outermost layers thereof. The portions of the flexible heat pipes disposed about the blanket provide a uniform heating or cooling pattern therein. The ends of the flexible heat pipes that are free from the blanket are thermally coupled to a combination heating and cooling system. When utilizing the heating system, the flexible heat pipes provide elevated temperatures at the blanket surfaces. When utilizing the cooling system, the flexible heat pipes provide lower than ambient temperatures at the blanket surfaces.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
A heat transfer blanket comprising a plurality of flexible sheath heat pipes, a pair of juxtaposed fabriclike layers having the marginal edges of one of said pair substantially in intimate contact with the marginal edges of the other of said pair, a portion of the length of each of said heat pipes adjacent one end thereof fixedly secured to and between said fabric-like layers disposed in spaced apart relationship, said spaced apart relationship providing substantially uniform distances between adjacent heat pipes, the other end of said plurality of said heat pipes fixedly secured to a solid metallic rod, said rod in intimate thermal contact with a source of thermal energy.
Claim 2
Dependent Claim
110 words
A heat transfer blanket comprising a plurality of flexible sheath heat pipes, a pair of juxtaposed fabriclike layers having the marginal edges of one of said pair substantially in intimate contact with the marginal edges of the other of said pair, a portion of the length of each of said heat pipes adjacent one end thereof fixedly secured to and between said fabric-like layers disposed in spaced apart relationship, said spaced apart relationship providing substantially uniform distances between adjacent heat pipes, the other end of said plurality of said heat pipes fixedly secured to a solid metallic rod, said rod in intimate thermal contact with a source of thermal energy.
Claim 3
Dependent Claim
23 words
The heat transfer blanket as claimed in claim 1 further comprising a thermostatic switch controlling the temperature of said source of thermal energy.
Claim 4
Dependent Claim
24 words
