Abstract
A head cooling device includes a central portion that has a predetermined volume of space and is seated on a top portion of the user's head; and a plurality of wing portions radially connected to the central portion and extending in a fan shape, wherein each of the wing portions includes a plurality of chambers each having a predetermined volume of space in which a phase change material is charged, and a plurality of bridges configured to partition and connect each of the plurality of chambers. The central portion and each of the plurality of chambers further incudes a cushioning member to protect the user's head and improve safety by absorbing and alleviating an impact applied from outside.
Claims19
A head cooling device, which is charged with a phase change material (PCM) and performs a cooling function by seating on a user's head, the head cooling device comprising:
- a central portion that has a predetermined volume of space, has a flange extending from an outer circumference thereof, and is seated on a top portion of the user's head when in use;
- and
- a plurality of wing portions radially connected to the central portion via the flange and extending in a fan shape,
- wherein each of the wing portions includes a plurality of chambers each having a predetermined volume of space in which the PCM is charged, and a plurality of bridges configured to partition and connect each of the plurality of chambers,
- wherein each of the plurality of bridges is configured to partition and separate the plurality of chambers from each other, and to define each of the plurality of chambers as a closed space that does not allow the PCM to flow to an adjacent chamber across each bridge, and
- wherein each of the plurality of bridges is configured to serve as a hinge that allows each of the plurality of chambers of the plurality of wing portions to be sequentially bent downward from the top portion of the user's head along an outer circumference surface thereof so as to be in close contact with the user's head when in use, thereby improving a cooling effect.
A head cooling device, which is charged with a phase change material (PCM) and performs a cooling function by seating on a user's head, the head cooling device comprising:
- a central portion that has a predetermined volume of space and is seated on a top portion of the user's head when in use;
- a plurality of wing portions radially connected to the central portion and extending in a fan shape,
- wherein each of the wing portions includes a plurality of chambers having a predetermined volume of space in which the PCM is charged, and a plurality of bridges configured to partition and connect each of the plurality of chambers, and
- wherein each of the plurality of chambers includes a cushioning member that absorbs and alleviates an external impact,
- wherein the plurality of wing portions includes a first sheet that is pre-formed with a portion of the space of each chamber, and a second sheet that is pre-formed with a residual portion of the space larger than that of the first sheet and is joined to the first sheet.
A head cooling device, which is charged with a phase change material (PCM) and performs a cooling function by seating on a user's head, the head cooling device comprising:
- a central portion that has a predetermined volume of space and is seated on a top portion of the user's head when in use;
- and
- a plurality of wing portions radially connected to the central portion where each of the wing portions includes first, second and third chambers each having a predetermined volume of space in which the PCM is charged and connected through first and second bridges configured to partition and connect the first to third chambers, respectively,
- wherein the central portion and each of the first, second and third chambers have a convex outer surface and include a cushioning member that absorbs and alleviates an external impact, and
- wherein the plurality of wing portions includes a first flat sheet, a second sheet that is pre-formed with a space of the central portion and each space of the first to third chambers, respectively and is joined to the first sheet, and a third sheet that is pre-formed with a space to accommodate the cushioning member and is joined to the third sheet.
A head cooling device, which is charged with a phase change material (PCM) and performs a cooling function by seating on a user's head, the head cooling device comprising:
- a central portion that has a predetermined volume of space and is seated on a top portion of the user's head when in use;
- and
- a plurality of wing portions radially connected to the central portion and extending in a fan shape,
- wherein each of the wing portions includes a plurality of chambers having a predetermined volume of space in which the PCM is charged and a plurality of bridges configured to partition and connect each of the plurality of chambers,
- wherein each chamber includes a cushioning member that absorbs and alleviates an external impact,
- wherein an inner space of the central portion is divided into two spaces with a semicircular cross-section through a partition wall, each filled with the PCM and including a cushioning member, and
- wherein the plurality of wing portions is radially connected from the central portion in an even number, so that the head cooling device is foldable in half.
