Abstract

A cooling device attachable to a hard hat to deliver a cooling airflow to a crush space between a head of a wearer and a shell of the hard hat with a brim generally includes a housing having a fan assembly that draws the cooling airflow in through an intake opening in the housing and out of an outlet. The intake opening is disposed on an exterior of the hard hat and the outlet is positioned under the brim of the hard hat. An air tube extends from the outlet under the brim and into the crush space. A surface of the air tube is opposed from a surface of the housing to be operable to hold a portion of the brim between the surface of the air tube opposed from the surface of the housing. A fastening assembly releasably connects the housing to the hard hat.
