Claims
- 1. A personal cooling device, comprising
- a sealed garment containing a working fluid in an evaporator section which fluid is adapted to be vaporized by heat generated from a person wearing the garment;
- a bed consisting of one of an adsorbent, an absorbent and other known desiccants; and
- a pressure-regulating valve operatively communicating the garment and the bed for maintaining a desired pressure in the evaporator section transport of the working fluid vapor.
- 2. The personal cooling device according to claim 1, wherein the evaporator sector is parallel multi-passage heat exchangers oriented so as to be one of vertically disposed and inclined slightly from the vertical.
- 3. The personal cooling device according to claim 1, wherein the garment contains a lower section containing the working fluid as a saturated liquid and an upper section containing the working fluid as saturated vapor.
- 4. The personal cooling device according to claim 1, wherein means is operatively arranged between the evaporator section and the bed for preventing liquid from entering the bed during tilting.
- 5. The personal cooling device according to claim 1, wherein means is provided for recharging the device upon saturation of the bed.
- 6. The personal cooling device according to claim 2, wherein the garment contains a lower section containing the working fluid as a saturated liquid and an upper section containing the working fluid as saturated vapor.
- 7. The personal cooling device according to claim 6, wherein means is operatively arranged between the evaporator section and the bed for preventing liquid from entering the bed during transient tilting.
- 8. The personal cooling device according to claim 7, wherein means is provided for recharging the device upon saturation of the bed.
