Abstract
A motorcycle helmet defines a cavity in a hard fiber shell. A thermo-electric heat pump is mounted in the cavity, and a light metal rediator is bonded to both shell and pump. One way conductors energize the heat pump from a motorcycle battery source to pump heat from the hard fiber shell to the radiator. A flexible blatter filled with heat transfer liquid is mounted in the hard fiber shell and below the heat pump and in thermal contact with a wearer's head and the heat pump, for conducting head heat to the pump to electrically pump to the radiator for radiation to the atmosphere.
Claims8
Thermo-electric cooled headgear comprising:
- (a) a hard shell having a cavity defined in and through said hard shell;
- (b) thermo-electric heat pump means mounted in said cavity;
- (c) thermal radiation means closing said cavity and extending along a portion of the exterior of said shell, said thermal radiation means being connected to said heat pump means whereby heat is transferred by said heat pump means through said cavity and from said heat pump means for heat radiation from said radiation means;
- (d) insulated electrical conduction means operationally connected to said heat pump means and connectable to an electrical power source for energizing said heat pump to electrically pump heat to said radiation means, and;
- (e) liquid heat transfer means mounted in said headgear for transfering heat between a wearer's head and said heat pump, said liquid heat transfer means comprising bladder means conformable in shape to the contour of a wearer's head, said bladder means being fillable with a heat transfer liquid whereby heat transfer liquid convection currents transfer heat from the wearer's head, around said contour, and to said heat pump means.
Thermo-electric cooled headgear comprising:
- (a) a hard shell having a cavity defined in and through said hard shell;
- (b) thermo-electric heat pump means mounted in said cavity in such a manner that said heat pump means does not significantly protrude into the head-accommodating space defined by said hard shell;
- (c) thermal radiation means closing said cavity and extending along a portion of the exterior of said shell, said thermal radiation means being connected to said heat pump means whereby heat is transferred by said heat pump means through said cavity and from said heat pump means for heat radiation from said radiation means;
- (d) insulated electrical conduction means operationally connected to said heat pump means and connectable to an electrical power source for energizing said heat pump to electrically pump heat to said radiation means;
- and,
- (e) liquid heat transfer means mounted in said headgear for transfering heat between a wearer's head and said heat pump, said liquid heat transfer means comprising bladder means conformable in shape to the contour of a wearer's head, said bladder means being fillable with a heat transfer liquid whereby heat transfer liquid convection currents transfer heat from the wearer's head, around said contour, and to said heat pump means.
