Abstract
The present invention uses high thermal-conductivity materials to act as heat pipes around or through a soft body armor vest to transfer heat away from the body of the wearer. A moisture wicking layer is also incorporated and used to pull moisture from the body of the wearer and disperse the moisture to the outer surface where it can evaporate. An evaporative cooling effect, which is a one-way phase change process that is similar to that of the human body, removes thermal energy from the high thermal-conductivity materials at the outside surface of the vest dissipating the heat into the environment.
