1. A body wrap for rapidly cooling a part of the body, comprising(a) a phase change material having a melting point of between about −10 and 6 degrees Centigrade;(b) a gel or viscous fluid carrier in which the phase change material is substantially evenly distributed;(c) a fluid-impermeable, conformable, sealed envelope surrounding the phase change material and the carrier;(d) at least one layer of insulation adjacent to a first side of the envelope;(e) a fastener means for removably fastening the body wrap around a part of the body; and(f) a heat tube layer adjacent to an opposite, second side of the envelope, the heat tube layer being comprised of a plurality of heat tubes connected to one another. 2. A body wrap according to claim 1, wherein the envelope is a urethane film. 3. A body wrap according to claim 2, wherein the fastener means is strips of hook and loop attached along one side of the body wrap. 4. A body wrap according to claim 2, wherein the phase change material is microencapsulated with a polymer coating, forming generally spherical PCM/polymer microcapsules which range in diameter between about one and about 100 microns. 5. A body wrap according to claim 2, wherein the carrier is a silicone fluid. 6. A body wrap according to claim 1, wherein the carrier is an oil. 7. A body wrap according to claim 1, wherein the carrier is urethane gel. 8. A body wrap according to claim 1 wherein the phase change material is a C12 to C14 alkane, or a combination thereof. 9.

A body wrap for rapidly inducing hypothermia, comprising(a) a fluid-impermeable, flexible, conformable envelope;(b) a mixture of from about 10 to about 75 weight % of alkanes having a carbon chain length of between 10 and 14 and from about 25 to about 90 weight % of a gel or viscous fluid carrier in which the alkanes are substantially evenly distributed, the mixture being sealed within the envelope;(c) at least one layer of insulation adjacent to a first side of the envelope;(d) a fastening means for fastening the body wrap around a part of the body; and(e) a heat tube layer adjacent to a second, opposite side of the envelope, the heat tube layer being comprised of a plurality of heat tubes connected to one another. 12. A body wrap according to claim 11, wherein the alkane is microencapsulated with a polymer coating, forming generally spherical microcapsules ranging in diameter between about one and about 100 microns. 13. A support surface according to claim 11, further comprising a net suspended within at least one of the heat tubes. 14. A body wrap according to claim 1, which does not comprise a power source or microprocessor. 15. A body wrap according to claim 11, wherein the envelope is a urethane film. 16. A body wrap according to claim 11, wherein the carrier is a mineral oil, a silicone fluid, or a urethane gel. 17. A body wrap according to claim 15, further comprising an outer protective layer adjacent to an outer side of the insulation layer, and an inner, conformable layer adjacent to an opposite side of the envelope. 18. A body wrap according to claim 11, wherein the alkane is dodecane, tridecane, tetradecane, or a mixture thereof. 19. A cooling body wrap for rapidly inducing hypothermia, comprising:(a) a fluid-impermeable, flexible, conformable envelope;(b) a mixture of from about 10 to about 75 weight % of alkanes having a carbon chain length of between 10 and 14 and from about 25 to about 90 weight % of a gel or viscous fluid carrier in which the alkanes are substantially evenly distributed, the mixture being sealed within the envelope;(c) at least one layer of insulation adjacent to a first side of the envelope;(d) a fastening means for fastening th e body wrap around a part of the body; and further comprising at least two adjacent heat tubes within the envelope, at least one of the heat tubes containing a refrigerant liquid. 20. A cooling body wrap for rapidly inducing hypothermia, comprising:(a) a fluid-impermeable, flexible, conformable envelope;(b) a mixture of from about 10 to about 75 weight % of alkanes having a carbon chain length of between 10 and 14 and from about 25 to about 90 weight % of a gel or viscous fluid carrier in which the alkanes are substantially evenly distributed, the mixture being sealed within the envelope;(c) at least one layer of insulation adjacent to a first side of the envelope;(d) a fastening means for fastening the body wrap around a part of the body; and further comprising a plurality of heat tubes within a second, gel or viscous fluid-filled envelope, at least one of the heat tubes containing a refrigerant liquid with a boiling point between about 0 and about 20 degrees Centigrade.
