Ventilated athletic cap

A hat or cap comprising an adjustable headband, a semi-rigid visor attached to said headband and extending along the front and both sides of the cap, and a canopy attached to the outer edges of said visor. The canopy is made of formed cloth or semi-rigid material so as to maintain its shape and keep a spaced relation between the cap and the head of the wearer. The canopy further contains air vents in the front and rear so as to permit the unrestricted flow of air about the head of the wearer.

The tube sheet of a heat exchanger supports a plurality of tubes made from a material such as titanium. A shield is provided for the tube sheet and is welded to the tubes. The shield is made from the same material as the tubes and is spaced from the tube sheet to define a fluid chamber containing fluid at a pressure in excess of the pressure of the liquid flowing through the tubes.
