Abstract: A light-weight heat-reflective substructure for a hat can be comprised of a semi-rigid bottom loop, top loop, two or more angled supports, and heat-reflective panels. The bottom loop can have a diameter commensurate with the size of the hat. The top loop can have a diameter commensurate with the diameter of the hat's crown. Each angled support can be coupled to the bottom and top loops, creating a three-dimensional frame. The angle that each angled support is coupled can be a minimum of fifteen degrees from a horizontal plane. The heat-reflective panels can couple to the angled supports of the frame, covering space between angled supports. The heat-reflective substructure can reduce an amount of thermal radiation transferred to the user by five percent or more as compared to wearing the hat without the heat-reflective substructure. Angling of the panels can increase an amount of surface area available for reflection.

Abstract: An improved welding helmet encloses a welders head and a portion of the neck. The helmet contains a fan, filter and thermoelectric cooling module to provide clean, cool air that reduces welding fume levels below suggested maximums and provides cool air to the welders head and neck area making their body feel cooler. Air exhausted from the helmet is captured and further utilized to significantly improve system efficiency by causing it to be in contact with the hot side heat sink that is a part of the thermoelectric cooling module assembly. The use of an external power source, including readily available welding power, is suggested as one option for supplying system power. An optional configuration is presented where an external container strapped to the welders body is employed containing the fan, air filter and thermoelectric cooling module and is connected to the helmet by cool air intake and exhaust air hoses.

A radiant barrier attached to the inner surface of the heat shield assists in dissipating heat away from the helmet surface. The air gap also permits air to circulate through freely, thereby significantly reducing the heat transfer to the exterior surface and interior of the helmet. The heat shield may be manufactured as an integral part of the helmet.

Abstract: The lack of air flow under body armor, helmets, and thick garments can lead to excessive moisture build up and discomfort on the wearers body due to lack of heat removal and effective evaporation of sweat. By incorporating wick covered heat pipes or thermal conductors with air flow channels in the apparel contact area between the garments, helmets, and body armor the effectiveness air flow cooling and evaporation of sweat can be restored. Humidity or temperature auto-actuated bi-material valves are used to control this air-moisture-heat flow to achieve a controlled comfortable humidity-temperature environment and avoid excessive cooling. Supplementary air pumps, filters, dehydrators, fluid pumps, heating fluids, and cooling fluids may be incorporated to enhance the effectiveness. Biocides and hydrophilic materials are also incorporated on the wick coverings to avoid biological growth and maintain performance to achieve a healthy environment for the wearer.

Abstract: This invention defines a welding helmet that encloses a welders head on five sides and with an optional skirt covers their neck. The helmet contains a fan, filter and cooling module to provide clean cool air that reduces welding fume levels in the breathing zone below suggested maximums. By providing cool air to the welders head and neck area their whole body will feel cooler. It suggests the use of an external power source to provide the energy required to have a fan of sufficient capacity to draw air thorough a quality filter so potentially hazardous constituents of welding fumes are captured. This externally supplied power allows the required cooling capacity thermal electric cooling modules to be used to significantly lower the ambient air temperature. This helmet allows the welding operator to have sufficient cooling to improve their overall work environment for one of the most objectionable welding issues, excess heat.
