In the Winter Olympic Games, athletes compete for gold and silver; off the field, keeping out of the cold is a common challenge of previous Winter Olympic Games. At the Pyeongchang Winter Olympics, the U.S. ski team was equipped with a high-tech jacket jacket. The jacket comes with automatic heating and the athletes are like draped in a stylish electric blanket. This smart and hot coat was quickly sold out as soon as it was listed, causing a sensation in the industry.
Four years later, smart heating products have almost become "standard", covering all aspects of the Beijing Winter Olympics. "Many of the staff at the Winter Olympics are equipped with graphene flexible heating materials. In addition to the Winter Olympic clothing, graphene heating technology also provides a guarantee for many Winter Olympic licensed goods, heated seats, carpets, and professional equipment on the field. Chen Lijun, head of the special project of China Hangfa Graphene Materials Winter Olympics and chairman of Beijing Innovation Aishangjia Technology Co., Ltd., said.
Graphene heating clothing.
Graphene is currently the material with the highest thermal conductivity, in the case of electricity, by the carbon molecules between each other friction, collision to produce thermal energy, thermal energy through the far infrared in a plane manner evenly radiated out. Textile flexible heating materials made of graphene resemble a piece of "cloth" that can be energized and heated. This "cloth" also offers the advantages of washability, softness, thinness, comfort and durability. Repeated washing, rubbing and cutting will not affect its efficacy.
"I used to wear a graphene warm down jacket to Zhangjiakou for testing. When it snows, the snow turns into water and seeps into clothes and shoes, and it feels very cold. Turn on the heat switch and soon the clothes are hot. Chen Lijun said. In addition to down jackets, they have also developed different products such as graphene heated scarves, graphene heated vests, graphene heated gloves, socks, etc., to meet the different needs of various venues and types of work.
Graphene hand warmer.
Ice pier hand warmers are also empowered by graphene technology. With two temperature adjustments of 45°C and 55°C, this hand warmer is the first application of graphene technology in the licensed product of the Winter Olympic Games.
The cloud broadcast backpack of this Winter Olympic Games also uses graphene heating material. Due to the extremely low ambient temperature of the Winter Olympic venues and the competition site, the design of the cloud broadcast backpack has added a graphene heating layer and an insulation layer. This makes the backpack both easy to carry and can instantly generate a temperature rise of 50 ° C to ensure the normal operation of the equipment in a low temperature environment.
Chen Lijun said that graphene heating technology not only serves the Beijing Winter Olympics, but also plays a role in the fields of automotive thermal management systems, low-temperature environment special heating clothing and clothing, medical and health equipment, etc., and makes full use of the results of the Winter Olympics.
