- Abstract: Objective:To design an electrically-heated dry diving suit with a portable power supply for divers to keep warm in a low temperature underwater environment.Methods:To synthesize the technological solutions of waterproofing, thermal insulation, and electrical heating, to design an electrically-heated dry diving suit with a waterproof layer, a heating and thermal insulation layer, and an underwater lithium battery pack.Results:The results of both unmanned and manned testing showed that the electrically-heated dry diving suit with water tight, thermal protection with CLO value of 3.155, and electrically heating could, ensure that divers maintain their core body temperature above 35.8℃ over 5 h in (10±2)℃ underwater environments.Conclusion:The electrically-heated dry diving suit can electrically generate heat and keep divers warm underwater, prevent hypothermia of divers and maintain their normal body temperature in a high pressure and cold environment, so as to improve their underwater operation capability.
