Thermal control covers
View Patent ↗A heat transfer cover mitigates temperature changes of an object. A cover body is configured to receive the object. A plurality of heat transfer channels are defined in an interior of the cover body. The channels are arranged to transport a heat transfer fluid in thermal communication with the object. An inlet port is configured to connect the plurality of channels with a source of the heat transfer fluid. An interior surface of the cover body may substantially conform to a shape of an exterior of the object. A plurality of lands may be defined in the interior of the cover body. The lands are arranged to engage the exterior of the object. The heat transfer channels may be defined between adjacent lands. At least a first end of the cover body may define an opening. The at least first end and the object are substantially sealed at the opening.

10. The cover of claim 1 , wherein the gaseous heat transfer fluid includes ambient air.
11. The cover of claim 1 , wherein the gaseous heat transfer fluid includes at least one of:
air having a temperature less than ambient when a temperature of the object is higher than an original temperature of the object; and
air having a temperature greater than ambient when a temperature of the object is lower than an original temperature of the object.
12. A heat transfer cover for mitigating temperature changes of an object, the cover comprising:
a cover body configured to receive therein at least a portion of an object, an interior of the cover body substantially conforming to a shape of an exterior of an object received therein, the interior of the cover body defining a plurality of lands that are arranged to engage the exterior of the object, the interior of the cover body further arranged to cooperate with an exterior of an object received therein to define a plurality of heat transfer channels that are arranged to flow a gaseous heat transfer fluid therethrouah and over the exterior of the object;
an inlet port configured to connect to a source of the gaseous heat transfer fluid; and
a plenum arranged to distribute the gaseous heat transfer fluid from the inlet port to the plurality of heat transfer channels.
13. The cover of claim 12 , wherein the cover body includes at least a first end that defines an opening.
14. The cover of claim 13 , wherein the at least first end of the cover body and the object are substantially sealed at the opening.
15. The cover of claim 12 , wherein the cover body includes first arid second cover body members.
16. The cover of claim 15 , wherein the first and second cover body members are hingedly attachable to each other.
17. The cover of claim 12 , wherein the gaseous heat transfer fluid includes ambient air.
18. The cover of claim 12 , wherein the gaseous heat transfer fluid includes at least one of:
air having a temperature less than ambient when a temperature of the object is higher than an original temperature of the object; and
air having a temperature greater than ambient when a temperature of the object is lower than an original temperature of the object.
19. A method of mitigating temperature changes in an object, the method comprising:
receiving at least a portion of an object in a cover body;
causing temperature of the object to change; and
flowing a gaseous heat transfer fluid through a plurality of heat transfer channels defined by an interior of the cover body and an exterior of an object received therein such that the gaseous heat transfer fluid flows over an exterior of the object.
20. The method of claim 19 , wherein the gaseous heat transfer fluid includes ambient air.
21. The method of claim 19 , wherein:
causing temperature of the object to change raises temperature of the object; and
flowing the gaseous heat transfer fluid causes heat to be transferred from the object to the gaseous heat transfer fluid.
22. The method of claim 21 , wherein causing temperature of the object to change includes raising pressure of the object.
23. The method of claim 21 , wherein the gaseous heat transfer fluid includes air having a temperature less than ambient.
24. The method of claim 19 , wherein:
causing temperature of the object to change lowers temperature of the object; and
flowing the gaseous heat transfer fluid causes heat to be transferred from the gaseous heat transfer fluid to the object.
25. The method of claim 24 , wherein causing temperature of the object to change includes lowering pressure of the object.
26. The method of claim 24 , wherein the gaseous heat transfer fluid includes air having a temperature greater than ambient.
