Abstract

A head cooling apparatus is provided for cooling a head of a user. The head cooling apparatus includes a portable pump assembly having a foldable heat exchanger formed into a pocket to substantially receive a replaceable cooling source, the foldable heat exchanger including a first exchanger half including a channel, a center portion connected to the first exchanger half, and a second exchanger half connected to the center portion. The head cooling apparatus also includes a headgear assembly in fluid communication with the portable pump assembly, the headgear assembly configured to be worn adjacent a user's head, the headgear assembly including a conformable pouch configured to be positioned adjacent a user's head. The first exchanger half and second exchanger half are foldable along the center portion such that a replaceable cooling source is substantially sandwiched between the first exchanger half and second exchanger half.

Dependent claims

A head cooling apparatus comprising:

a portable pump assembly including
a replaceable cooling block,
a first foldable heat exchanger located adjacent to the replaceable cooling source including:
a flexible first exchanger half including a channel, an inlet port, and an outlet port;
a center portion connected to the first exchanger half;
and
a flexible second exchanger half connected to the center portion, the second exchanger half including a channel, an inlet port, and an outlet port;
wherein the first exchanger half and second exchanger half are foldable along the center portion such that the replaceable cooling block is sandwiched in a pocket formed between the flexible first exchanger half and flexible second exchanger half, and
a pump in fluid communication with the first heat exchanger,
a pack containing the portable pump assembly and worn by a user;
a headgear assembly worn adjacent the user's head, the headgear assembly comprising a second heat exchanger positioned adjacent a user's head, a headgear assembly inlet port and a headgear assembly outlet port;
a first flexible fluid transfer conduit connected to the outlet port of the portable pump assembly and the headgear assembly inlet port;
a second flexible fluid transfer conduit connected to the inlet port of the pump assembly and the headgear assembly outlet port;
wherein the portable pump assembly, headgear assembly, first flexible fluid transfer conduit and second fluid transfer conduit form a loop that is sealed such that no gas is present in the loop so that the portable pump assembly circulates a fluid within the loop regardless of an orientation of a user.
