Cooling Device for Combat Vehicle Crew Drinking Water. Phase 1.

Abstract

The objective of this SBIR A87-156 Phase I Project was to evaluate the feasibility of a Drinking Water Cooling System for combat vehicle crews that can maintain a water temperature of 75 F, when the exterior temperature is as high as 120 F and under the all-buttoned-up condition the vehicle internal temperature can be as high as 150 F. The crew's water canteen is affected by that high temperature and it is very difficult to encourage the crew to drink a sufficient quantity of water to maintain their body electrolyte balance. The concept incorporated a compound system consisting of a Thermal Electric Cooler (TEC) in series with a Water Evaporative Cooler (WEC). A WEC system alone cannot cool the air from 150 F to 70 F, while the TEC system alone cannot operate effectively at heat rejection temperature higher than 160 F, but the two in series will make the system work well. This study is aimed at the proof of the working principle and the collection of data to make the novel system compact and requiring very little energy. Two breakthroughs were introduced during the study, 1) the use of a super saturated water mist in air created by an ultrasonic cooler and 2) the use of a heat pipe to extract the heat from the water.
