If you want to learn to design a heating line or develop products related to heat; you must master the calculation formula of the heating line, in order to smoothly develop the heating effect of the new product you want! For details, please refer to one. One customer wants to buy a hot seat cushion. The input voltage is 12V. The electric seat cushion specification: 35cm*35cm, and the heating temperature is 40 degrees. How to design this electric heating pad? Analysis: For example, the preferred power is 40 degrees according to experience, about 5w per W power, 35*35cm cushion area, and the length of the heating wire is about 2M, then the total power of the heating cushion is 10W. Detailed explanation 1: The current of the electric heating cushion is: 10W/12V=0.83A The total resistance of the heating wire: 12/0.83A=14.4 ohms per meter resistance value: 14.4 ohms/2M=7.2 ohms/M Detailed solution 2: The heating plate voltage: 12V Square/10W=14.4 ohm electric sheet current: 12/14.4 ohm=0.83A Meter resistance calculation: 14.4 ohms/2M=7.2 ohms II. The above formula is the heating line; welcome to buy Dongguan Xingguan Electric Heating Products Co., Ltd. ! Sincere, careful, careful, patient service, quality first!
