The present invention provides a portable system for cooling that is integrated into a wearable garment or carrying device. The device includes a Peltier thermoelectric cooler coupled to the garment. The thermoelectric cooler comprises a cold side plate and a hot side plate. The cold side plate is oriented proximate to the body of the wearer. The cooling device further comprises a thermal shield. The thermal shield comprises a thermally reflective surface that faces the wearer side of the garment. The device comprises a thermal conduction sheet coupled to the cold side of the thermoelectric cooler. The device further comprises a cold pack thermally coupled to a side of the thermal conduction sheet. The device comprises a blower configured to blow air across the hot side of the thermoelectric cooler and away from the garment.

A cooling fabric including a moisture-permeable inner surface layer, a spacer fabric and an outer surface layer, wherein the outer surface layer has an air permeability of at most 250 l/dm2/min at 500 Pa measured according to ISO 9237 and wherein the spacer fabric comprises monofilaments extending across the spacer fabric, wherein the monofilaments have a linear density of at least 250 dtex and wherein the monofilaments are present at a density of at most 800 monofilaments per square-inch.

An article is provided which includes a flexible body configured to cover part of a user's body, at least one humidity sensor coupled to the flexible body and configured to measure a humidity of the user's skin or an internal microclimate; at least one temperature sensor coupled to the flexible body and configured to measure a temperature of the user's skin or an internal microclimate; at least one microclimate control element coupled to the flexible body; a controller functionally coupled to the at least one humidity sensor and the at least one temperature sensor to receive measured humidity and temperature signals as an input and functionally coupled to the at least one microclimate control element, the controller being preprogrammed to maintain the internal microclimate under a discomfort threshold value; a user interface functionally coupled to the controller; a power supply; and a switch.

The present invention relates to a functional fabric. More specifically, the present invention relates to a functional fabric, which causes no skin irritation, has excellent washing durability and antibacterial and deodorizing properties, quickly discharges moisture generated from the human body, such as sweat or breath, and quickly diffuses heat.

A bionic air-conditioning garment, includes an air-conditioning garment body, a smart watch, and wireless temperature and humidity sensing sensors. A cooling water conveying system is disposed in each of seven block areas. The smart watch is connected to the controller through a wireless communication device. When a water pump works, liquid in a backpack water bag is transported to an outer layer of the air-conditioning garment body through labyrinth drip irrigation belts, and dispersed to the outer layer of the air-conditioning garment body. The outer layer of the air-conditioning garment body is hydrophilic to quickly expand water, so that the liquid expands to form a moisture permeable layer on the air-conditioning garment body. Under irradiation of external natural wind and sun, the bionic air-conditioning garment absorbs heat through gasification and evaporation of the liquid, which energy efficiency ratio is large and heat dissipation and cooling effects are better.

A garment has excellent contact cold sensation and gives persistent contact cold sensation but also can reduce heatful feeling and is suitably wearable in wearing scenes such as offices and homes. The garment includes one or plural fans for taking external air into a space between the garment and the body. A fabric of the garment has a contact cold/warm sensation value Q-max of 0.30 W/cm.sup.2 or larger and a basis weight of 250 g/m.sup.2 or less.

A ventilation apparatus includes a motor, a fan, a housing, and a ring. A projection protrudes from one of an outer peripheral surface of a peripheral wall part of the housing and an inner peripheral surface of the ring, whereas an engagement wall and a guide wall are provided on the other of the outer peripheral surface of the peripheral wall part of the housing and the inner peripheral surface of the ring. The guide wall has a guide surface configured to guide the ring rearward relative to the housing and to guide the projection to an engagement position at which the projection is abuttable on an engagement surface of the engagement wall. In a direction in which the projection moves away from the guide surface in a front-rear direction, an open space extends from the guide surface to an area that corresponds to an end of the second surface.

A head-mounted heat dissipation device includes a fan assembly and a wearing assembly. The wearing assembly is connected to the fan assembly to fix the fan assembly onto a head of a user. The fan assembly includes a casing and fans arranged in the casing. Air inlets and air outlets are defined in the casing. The air outlets are located on an inner side of the bottom surface of the casing, so that the air from the air outlets can be blown to the user's face. In addition, air guide strips are arranged side by side on a side of the air outlet within the casing for concealing the operation of the fans.

Personal wearable comfort device that distributes fresh air around the users waist and core to help cool via convective and evaporative cooling. The system includes an air distribution belt which houses a fan assembly source for generating air movement and a breathable channel with a relatively air impermeable wrap for directing air movement. The fan assembly source for generating air movement is removable from the belt and consists of a small impeller blower, rechargeable battery, printed circuit board to drive user interface with power on/off and level selections. The breathable channel for air distribution is built using a highly breathable material that is wrapped with one or more materials designed to maintain airflow throughout the interior of the belt and deliver a level of comfort to the user. There are holes/pores introduced to this wrap material to direct the airflow out of the belt and across the ideal regions of the user's body for optimized distribution and thermal cooling performance. This breathable channel for air distribution is adjustable, washable, and customizable to the user.

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.
