Description : note:cup not included. Product Description A: Specifications Two electrodes made of aluminum heat plate size is 7.4 * 3.8 * 15cm motor 1.5V-6V multiturn motor, a small fan diameter of 4.2cm, the center hole 2mm can switch control between your feet equipped with a thermoelectric effect chip. 2: Principles 1, using the temperature difference between the battery as a driver. 2, the temperature difference between the battery is the use of temperature differences, the Seebeck effect through the cell, so that the heat energy is directly converted into electrical energy. The temperature difference between the battery materials are generally two kinds of metals and semiconductors, the product is made using a semiconductor. 3, made with a semiconductor thermoelectric cell Seebeck effect is stronger, the higher efficiency of heat into electricity, and therefore, may be composed of a plurality of such batteries thermopile as a small power supply. Its working principle is that one end of the two different types of thermoelectric conversion material of N-type and P-type semiconductor, and placed in the high temperature state, and the other end open and give a low temperature, since the high-temperature side of the thermal excitation stronger effect, the hole and electron concentration higher than the lower temperature side, holes and electrons in such carrier concentration gradient driving diffusion to the low temperature end, thereby forming an electrical potential difference in the open end of low temperature; if the number of P-type and N-type thermoelectric conversion material connected together to form a module, can be obtained to a sufficiently high voltage, to form a thermoelectric generator Third: Operation 1, power generation: Remove the instrument with two cups were loaded into the hot water (45-60 degrees) and cold water, two feet were placed in a glass of water (a hot cup also available), after 15 seconds to open the instrument switch current , driven fan rotation. 2, refrigeration: 6V power supply Chiang positive and negative reverse into the power jack, the instrument can feel the cold phenomenon appears more than 30 seconds. Four: save Dry after two feet of water, put in the box, placed in dry occasions to avoid rusting aluminum plate. Country Approx.
