An apparatus is disclosed. The apparatus has a cooling fluid passage, a gaseous fluid blower disposed at an upstream portion or a downstream portion of the cooling fluid passage, and a liquid droplet sprayer disposed at the upstream portion of the cooling fluid passage. A surface portion of the cooling fluid passage is hydrophobic.

An electronic heating/cooling garment includes: a neck part, a collar (neckband), or an underarm part where a Peltier device (31) is placed; and a front body or a back body where a heating medium circulation path (35) and a battery (35) are placed, the battery (35) being configured to supply electric power to a pump (341) and the Peltier device (31). The heating medium circulation path (35) is composed of a flexible thermally conductive material having a tubular shape and holds a heating medium therein in an airtight manner. The heating medium circulation path has a first electrode and a second electrode on its outer surface. The first and second electrodes are configured to supply the electric power from the battery (35) to the Peltier device (31) and the pump (341).

An outerwear garment includes a jacket, at least one thermoelectric module, a thermal spreading pad and a mesh cover. The jacket has a flexible garment layer conforming to all or part of the human torso. The thermoelectric module (TEM) is coupled to the garment layer and has first and second sides. The TEM provides a temperature change between the first side and the second side responsive to applied electrical operating power. The thermal spreading pad has a surface thermally coupled and substantially conforming to at least a portion of the human torso, and exchanges heat with the first side of the TEM. The flexible mesh cover is coupled to the garment layer and disposed over the TEM. The jacket also supports an electrical power source that provides electrical operating power to the TEM.

A nursing cover having an integrated cooling neck fan in which the integrated cooling neck fan is bladeless, removable, and bendable over a range of angles. The inside top area of the nursing cover includes at least one hook and loop strip that extends in a horizontal direction. Additional hook and loop strips are on a top surface of the cooling neck fan such that the cooling neck fan is removably attachable to the inside top area of the nursing cover. A user grabs the two ends of the neck fan to bring the nursing cover closer or further away and adjust distance of air vents on the neck fan from a nursing child covered by the nursing cover while held by the mother. The nursing cover includes a neck strap and a long fabric portion that thoroughly covers the mother and nursing child.

A cooling system of an upper garment wherein the cooling pad is formed from a coil of conduit disposed over the chest/heart-region of the user beneath the upper garment. The hear-region disposition of the low-profile coiled cooling pad facilitates the cooling effect to be circulated by way of the user's circulatory system. The cooling pad is fluidly connected to a reservoir and pump for urging coolant flow between the three elements. The power supply, reservoir and fans for cooling the latter two elements are disposed external to the upper garment, so that heat they may generate can dissipate away from the user.

A fully adjustable hybrid personal cooling and heating system is configured to remove or supply heat from/to a human user. The system is specifically designed to provide up to 8-hours of high efficiency adjustable cooling or heating when worn and operated by a user. The personal cooling and heating system use non-toxic room-temperature liquid metal as primary coolant and phase-change material as secondary coolant. The primary coolant is pumped using an active powered pump which absorbs heat from the user's body, and passively release the heat to the secondary coolant making the invention a hybrid cooling/heating system. Passive heat release is facilitated by extreme high thermal conductivity of the primary coolant. Also, the secondary coolant is thermally insulated from the environment allowing on-demand heat absorption only from the primary coolant.

To pump-condition a garment that covers at least a portion of an individual, at least one fluid-circulating vent panel circulates a fluid adjacent the garment in an effort to condition the individual. A pump provides a motive force to circulate the circulating fluid through each vent panel, and a conduit is routed within the garment and couples the pump and each vent panel. A controller controls the pump to provide the motive force, and a power source provides power to operate the pump and the controller. The pump may be an ultrasonic piezoelectric pump.

The present disclosure provides an intelligent refrigerating garment. The intelligent refrigerating garment includes a garment body and a water circulation refrigerating device. Water storage layers are disposed on an inner side of the garment body. A water outlet of the water circulation refrigerating device is communicated with a water inlet of the water storage layers. A water inlet of the water circulation refrigerating device is communicated with a water outlet of the water storage layers.

Disclosed are cooling materials for clothing and other body gear that may use a discontinuous pattern of highly absorbent polymers coupled to a base fabric that has a low resistance to moisture spread (e.g., a high wicking rate) and lower absorption properties compared to the highly absorbent polymer elements, to manage moisture (e.g., sweat) and body heat. The absorbance of the highly absorbent polymers is greater than that of the base fabric, such as at least two times greater, and the highly absorbent polymer elements may be non-endothermic.

A body cooling apparatus is configured for wear under an outer garment such as those worn by welders. The apparatus is constructed of cloth-covered air tubing which distributes a supply of received compressed air. The user wears the tubing harness much like a vest. When the harness is connected to a compressed air source, the compressed air is vented through the cloth-covered tubing to assist in cooling the user's body.
