The working principle of the thermal insulation Cup

There are a lot of insulation products on the market, such as insulation Cup, thermos flask, thermos bottle, insulation boxes etc.. So, these products, how to play the role of heat insulation of? Viewed from the outside, they and other utensils and not much difference! Want to know how is the effect of heat preservation, first you must understand how heat is transmitted. The heat transmission in three ways, namely, convection, radiation transfer. Radiation is energy in some form, out. When the body temperature is high, the energy is relatively large, naturally a lot out, therefore the hot stuff quickly cooling. Convection, which is simply the energy flow between objects. High temperature of the object, the energy is relatively large, the heat will flow to the body temperature is low, in order to achieve the balance of energy. When the energy balance, heat things of course will get cold. Transfer, energy through a medium, spread to other objects. Heat energy can be spread in the vast majority of objects, whether it is a gas, liquid or solid. The principle of the thermal insulation Cup, is from the three aspects, effectively preventing the heat transmission, thus plays the role of insulation. First of all, the internal insulation product is silver material, heat reflection can speak the radiated back, it can't give. In addition, the most important, insulation products generally have two layers of material composition, decimating air, forming a vacuum state. Vacuum, heat can not be with the outside air convection, nor is there any substance to transfer out, that is to say, insulation products into a "Chamber of secrets", the heat "imprisoned", so as to achieve the effect of heat preservation.
