Abstract A personal cooling device having a cabinet containing cooling means, the cabinet having a forwardly projecting port member and a base extending beneath the port member. An elongated flexible tube composed of air permeable resin coated textile material is connected to the port member and is of sufficient length to receive a person lying on a bed or the like. The tube forms conduit means for conducting cool air from the cooling means when the cabinet is at the foot of the bed.
