Abstract
The invention relates to a slurry-cooled helmet and to a head-cooling system. The helmet includes a hollow shell within which is positioned a plurality of tubes connected between an inlet and a discharge manifold. The manifolds are respectively connected to inlet and outlet means in the helmet shell.
Claims21
A frozen packed helmet comprising:
- a hollow shell including an inner wall contoured generally to be mounted on the head of a person;
- a plurality of tubes, positioned within said shell so as to extend substantially parallel to each other through a substantial portion thereof;
- an inlet manifold positioned within said shell connected to one end of each of said tubes;
- a discharge manifold positioned within said shell connected to the other end of each of said tubes;
- inlet and outlet means carried by said shell connected respectively with said inlet and discharge manifolds for selectively admitting a coolant slurry comprising frozen solids and a liquid carrier to said helmet and for withdrawing liquid therefrom;
- filter means provided adjacent the connection between each of said tubes and said discharge manifold for preventing the discharge of frozen solids together with liquid whereby said tubes may be filled with said frozen solids initially void of the liquid carrier, and means for closing said inlet and outlet means to trap said frozen solids therein.

A head-cooling system comprising:
- a helmet having a hollow shell and including an inner wall contoured generally to be mounted on the head of a person;
- a plurality of tubes positioned within said shell so as to extend substantially parallel to each other through a substantial portion thereof;
- an inlet manifold positioned within said shell connected to one end of each of said tubes;
- a discharge manifold positioned within said shell connected to the other end of each of said tubes;
- inlet and outlet means carried by said shell connected respectively with said inlet and discharge manifolds;
- means for producing a slurry of frozen solids and means for transporting said slurry to the inlet means of said helmet shell and for withdrawing liquid substantially free of frozen solids from the outlet means of said helmet shell and for returning said liquid to said slurry-producing means;
- and,
- filter means provided adjacent the connection between each of said tubes and said discharge manifold for preventing the discharge of frozen solids together with liquid.
