Q&A of Professor Xie--About the Heat-storage Heating Garment
Model: GB-X1
I am a professor of physics (retired) and the inventor of this product and I'd like to communicate with you with regard to several questions.
I. What is Heat-storage Heating Garment
At present, there are only electric heating garment on the market, which takes lithium battery as the power supply and carbon fiber or heating wire as the heating unit to heat up the human body against coldness. Beijing Guangshunhe Technology Co., Ltd. has launched heat-storage heating garment recently after it had launched solar heating garment. It is another heating garment product first originated domestically. Heat-storage heating garment means to store heat with heat storage agent and to release heat for human body through heat conduction to heat up human body against coldness and make people feel warm.
II. The Structure of Heat-Storage Heating Garment
It is configured with a vest, 3 pockets back and forth the and a heat storage bag. The heat storage bag is a transparent nylon bag, with 280g heat storage agent in each bag. To keep the human body safe, there are 3 thermal insulation bags in stock to avoid burn.
III. Introduction to Heat Storage Agent and Technical Parameters
The heat storage agent is composed of organic polymer materials. It is white and solid particles with pearl luster. It is insoluble in water but soluble in ethyl alcohol, especially in hot ethyl alcohol. Its melting point is 62℃ and its enthalpy is 208.7J/g. It is a heat storage material with good performance and comes into existence through independent R&D of our Company. The working temperature of the heat storage bag (280g) is 50±2℃. The heating time is 4 hours (up to 38℃), the temperature of the heat storage bag is 38℃ after 4 hours' heating.
IV. The Heat Storage Bag Can Be Used repeatedly for Many Times
The heat storage bag should be charged with heat before use. You only need to heat the heat storage agent until it melts into liquid, then you need to put it into the water for steaming and boiling for about 20 ~ 30 minutes or put it into another heating source with the temperature of 80~100℃ to melt the agent. The microwave oven is not suitable for the heat charging of the heat storage bag and the heat storage bag can be used repeatedly for many times.
V. Notes:
This product is first originated in China and has just been launched on the market. There are still some deficiencies in it, so any criticism and opinion for improvement is welcome.
