Disclosed herein are thermally conductive materials, including, for instance, thermally conductive tubing, thermally conductive devices and/or systems (e.g., apparel, backpacks, and the like), and applications thereof. In at least one embodiment, a thermally conductive material is disclosed that is made from one or more base polymers and one or more additives that increase the thermal conductivity of the thermally conductive material relative to the one or more base polymers. In additional embodiments, a cooling vest and a cooling backpack are disclosed, both of which are wearable by human users to keep their body temperature below a certain value. The vest and/or the backpack may include tubing through which coolant flows. The tubing is placed within the fabric and is arranged so that it contacts the user's skin.

The present disclosure discloses a precise temperature control device and method for a fluid circulation unit. The device includes a temperature controller, a cold source container, and a liquid cooling vest. The temperature controller includes a shell. a water tank, a first water pump, a second water pump, and a main control panel. The first water pump is connected to the cold source container and the water tank. The second water pump is connected to the water tank and the liquid cooling vest. The liquid cooling vest is connected to the cold source container and the water tank. The water tank is provided with a temperature sensor. The main control panel is electrically connected to an operation apparatus.

Multiple embodiments of a system are disclosed to draw heat away from the body through the palm, back of the hand, or forehead using a thermoelectric device. In doing so, the core body temperature may be lessened, allowing for quicker muscle recovery and better physical performance during exercise and/or during rest breaks between periods of exercise.

To provide a garment which can suppress stuffy feeling and heatful feeling in the garment to keep an environment in the garment comfortable and also has excellent wearing comfort and design so that it can be suitably used in a high temperature and/or high humidity environment and in various wearing scenes requiring comfort such as an office, a home and the like, it is provided that the garment made of a fabric having an air permeability of 50 to 500 cm.sup.3/cm.sup.2/s includes a blower fan unit and a path forming section for imparting directivity to wind in the garment inside the garment.

A portable body surface air cooling method and a device thereof are disclosed. A portable air compression and heat dissipation set at least composed of an air compression unit, an air heat dissipation passage set and a power unit. The device compresses air with normal temperature in an environment to form compressed air, transfers the compressed air through a transfer passage, dissipates the heat of the compressed air and lowers the temperature of the compressed air in the transfer process, making the compressed air with lowered temperature continuously self-expand to reduce the pressure and lower the temperature in the transfer passage, guiding the compressed air to a terminal expansion spraying/spreading position, The compressed air is directly sprayed to the body surface of the user to spread hot air layer and perform the processes of final expansion, heat absorption and temperature lowering. Accordingly, double cooling effects are achieved.

The garments described herein cool the human body and effectively reduce the working environment temperature. They can also reduce the temperature of the human body in time when exercising. The garments are provided with seals that improve fit and define a relatively closed space within the garments such that cold air is not easily emitted, which enhances the cooling effect.

A main garment body 1, which is formed using a cloth C that is gas-impermeable or is gas-permeable to the extent that the cloth can be inflated by the introduction of air by a fan 2 and which comprises a fan installation hole 13 for installing a fan 2, and an air discharge part 14 for discharging the air introduced by the fan 2, the main garment body having an outer surface space-maintaining means 17, a back body section inner surface space-maintaining means 18, and a front body section inner surface space-maintaining means 19 for maintaining a space between the cloth C and the wearer's body and/or between the cloth C and another garment worn over the main garment body 1. As a result thereof, it is possible to provide a main garment body of an air-conditioning garment and an air-conditioning garment for which the function is not easily reduced even when worn under another garment, etc.

The invention relates to a portable cooling vented apparatus, comprising: an array made of one or more thermoelectric cooler(s), each thermoelectric cooler having a cold side and a hot side, the cumulative cold sides and the cumulative hot sides of all the thermoelectric coolers define cold and hot sides of the array, respectively; one or more heatsinks at the hot side of the array; and at least one reservoir configured to supply liquid to the heatsink(s), by being adjoined to the heatsink(s) and/or with the aid of one or more liquid channels connected to said reservoir and installed in the interior of the cooling apparatus in proximity to, or within, said heatsink(s); wherein the apparatus is open to the surroundings.

A method of cooling using a thermoelectric cooler is also provided.

The invention relates to a composition comprising 50-99 wt. % of Na.sub.2SO.sub.4.10H.sub.2O and 0.1-5.0 wt. % of an alginic acid salt. Such composition may advantageously be used as a phase change material since the composition (and a pouch comprising the composition) remains flexible during the phase change. This was also the case when subjected to a high number of subsequent cycles of heating and cooling.

A cooling knee pad includes a housing having a base, a perimeter wall extending upwardly from the base, and an upper end defining an interior volume. A pad is affixed to the upper end of the housing. A power supply is operably connected to a cooling mechanism disposed within the interior volume of the housing. The cooling mechanism may include a Peltier cooling unit including a radiator, an electric fan, a water pump, and at least one buck converter. A pair of adjustable fasteners affixed to the housing is configured to secure the housing to a user such that the pad contacts a knee of the user. In this way, the user can kneel on the pad to comfortably support the knee and cool the knee with the cooling mechanism.
