A cooling and ventilation device (10), a cooling hat (20), a cooling shoe and a cooling backpack. The cooling and ventilation device (10) comprises: a housing (100), a ventilation assembly (200), a heat conduction frame (300) and a cooling assembly (400). Two ends of the housing (100) are respectively provided with an air inlet (110) and an air outlet (120). The ventilation assembly (200) is arranged at the position of the air inlet (110), and is used for bringing air into the housing (100). The heat conduction frame (300) is arranged within the housing (100). The cooling assembly (400) comprises semiconductor cooling plates (410) and heat conduction film layers (420), the semiconductor cooling plates (410) being arranged on the heat conduction frame (300), the heat conduction film layers (420) being attached to the side surfaces of the semiconductor cooling plates (410) away from the heat conduction frame (300). When the semiconductor cooling plates (410) are turned on, the sides of the semiconductor cooling plates (410) connected to the heat conduction film layers (420) are cooling ends, and heat in the air entering from the external environment can be absorbed by the heat conduction frame (300) in a rapid and timely manner. Thus, a cooling operation is performed on the air entering from the external environment in a rapid and timely manner, thereby ensuring that an airflow discharged from the air outlet (120) is a cold airflow.

Temperature control pouch attachment system, Frio, is a backpack (or other item) attachment with an insulated pouch, a gel ice pack, and heating pack. The device may be attached to a backpack or other item using various methods of attachment and it is removably coupled to, a backpack, car seat, suit jacket, police, military, and K9 vests. The pouch has 3 layers; the inside layer being waterproof; the second layer consists of an insulation material to keep the coolness or heat inside, and the outside layer is a polyester fabric material that will wick away any moisture created by the user wearer.

A solar adiabatic cooling vest. The cooling vest utilizes adiabatic evaporation to cool hot, dry air. Hot outside humid air is drawn by an exhaust fan through an air inlet over large particles of salt to lower the air humidity before passing through a wetted wick material. Heat in the air evaporates water in the wetted wick material, thus causing the air leaving the wick material to be saturated and at a lower temperature than the incoming air. The saturated air passes through a salt filter to lower the air's relative humidity. After exiting the salt filter, the cooled, drier air passes through an air filter to further lower its humidity and remove any salt particles from the air. The cooled air is then distributed through flexible outlet cooling tubes to a person's body, room, or enclosed space.

A cooling device includes an insulated cooler for holding cold fluid and ice. The device has a chamber, a cover, and a fill and drain valve. A tube connects the valve to a pump. The pump provides cold fluid to a bladder configured to fit a chair. The bladder can include a back portion, a seat portion and an internal manifold arranged in a closed loop for optimized cooling. The bladder can be reconfigured to cool a targeted portion of a user's body such as a leg, arm, neck, or torso.

Devices, systems, and methods for cooling and/or thermoregulation are disclosed, including thermoregulatory apparel. Such thermoregulatory apparel includes a cooling vest for human users to reduce their body temperature and/or to keep their body temperature below a certain value. The cooling vest may include a plurality of tubing arranged within the four-way stretch fabric used for the vest. Coolant flows through this tubing, which is arranged so that it contacts a user's skin while the user is wearing the vest. The composition and arrangement of the tubing can be matched with the type of fabric so that both the tubing and the fabric stretch in similar ways, ensuring that the tubing stays in contact with the user's skin. Also disclosed is a cartridge with a phase change material that is configured to refresh or recharge the cooling ability of the coolant when the coolant is passed through the phase change material.

Described herein is a perspiration evaporation device (PED) utilizing an evaporative column having an internal channel that can be secured to a garment or other accessory. As air passes over the top opening internal channel the internal air pressure within the evaporative column is reduced causing evaporated moisture from a user's skin to be drawn up the internal channel and away from the skin resulting in improved evaporation of moisture and a reduction in the core body temperature of a user.

A heat transfer system may include a heat transfer machine adapted to thermally couple to an heat transfer pack housed within an heat transfer device and transfer heat from the heat transfer pack using a power supply. The heat transfer device may include a housing and a heat transfer pack. The heat transfer pack may be adapted to thermally couple to the heat transfer machine, transfer heat to the heat transfer machine while thermally coupled to the heat transfer machine, and transfer heat from a mammal's skin when the heat transfer device is in contact with the mammal's skin and uncoupled from the heat transfer machine.

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.

A cooling device and methods of using the cooling device are described. The cooling device includes a flexible, elongated body member having a first end portion and a second end portion, or is adjustable with the first end portion and the second end portion attached, the elongated body member forming an elongated cavity extending substantially between the first end portion and the second end portion, the cavity having a first substance disposed within the cavity. The cooling device further includes at least one rupturable compartment contained within the cavity, the compartment having a second substance disposed within the compartment. The cooling device also includes fastening means disposed on at least one of the first end portion and the second end portion for detachably fastening the first end portion to the second end portion to secure the cooling device around a circumference of a body part.

An air circulating structure includes a housing having first, second and third sidewalls. The second and third sidewalls are positioned in a receiving space defined by the first sidewall and the second sidewall is positioned between the first and third sidewalls. The first sidewall has an opening and bending portions are formed at ends of the first sidewall and bending inward. Further, guiding elements are disposed on sides of the second sidewall facing the receiving space and positioned between the third sidewall and the bending portions. As such, air ducts are formed between the second sidewall and the first sidewall, the third sidewall, the guiding elements, the bending portions, respectively, and air vents are formed in junctions of the guiding elements with the bending portions and the third sidewall, thereby forming circulating air in the air ducts and vents to effectively improve the temperature regulating efficiency of an air-conditioning device.
