Abstract:
1. A heat transfer apparatus in combination with a portable hydration system, wherein said heat transfer apparatus and said portable hydration system combination are operationally secured to a user who is engaging in body movement, wherein said heat transfer apparatus and said portable hydration system combination including the user are located within an environment having freezing weather conditions, said heat transfer apparatus and said portable hydration system combination comprising: (a) a reservoir containing a fluid; (b) a first check valve in fluid communication with said reservoir, wherein said first check valve is oriented such that only flow from said reservoir is facilitated; (c) a pump having an inlet port and an outlet port, wherein said inlet port is in fluid communication with said first check valve; (d) a second check valve in communication with said outlet port, wherein said second check valve is oriented such that only flow from said pump is facilitated; (e) a first fluid communication line including a proximal end portion and a distal end portion having a first fluid communication line length and first longitudinal axis therebetween, wherein said proximal end portion is in fluid communication with said second check valve; (f) a second fluid communication line including an inlet end portion and an outlet end portion having a second fluid communication line length and second longitudinal axis therebetween, wherein said first fluid communication line length and said second fluid communication line length are continuously adjacent in position to one another, wherein said distal end portion and said inlet end portion are in fluid communication with one another and said outlet end portion is in fluid communication with said reservoir; and (g) a bleed valve in fluid communication with said distal end portion, wherein said bleed valve discharges a selectable intermittent fluid flowrate to the user for fluid consumption and said pump outputs a primary intermittent fluid flowrate that is greater than said intermittent fluid flowrate, wherein operationally said heat transfer apparatus acts to further help equalize said reservoir and said bleed valve temperatures through substantial continuous fluid circulation.
