电热取暖器是电流通过电阻后,将电能转变成热能,热能再以一定的热交换面借助于空气、油、水、物等介质,以对流、辐射、传导热的方式,达到人们取暖的目的。一、按照电热取暖器具对人体传送热量形式不同,可分为间接取暖和直接取暖两大类型。 1、间接取暖。 An electric heater is a device that converts electric energy into heat energy after the electric current passes through the electric resistance. The heat energy then uses a medium such as air, oil, water, and matter on a certain heat exchange surface to achieve the purpose of heating by convection, radiation, and conduction heat. . First, in accordance with the different forms of heat transmitted by the electric heating device to the human body, it can be divided into two types: indirect heating and direct heating. 1, indirect heating.
