具体实施方式detailed description
如图1-3所示，一种温差发电柴火灶，设该柴火灶为方体，最上面为台面1，下部为灶体2，灶体2采用金属外壳，起机械固定、机械支撑和电气安全接地作用。灶体内为上下两层，中间用金属过滤网4隔开，上层由传热金属板11及温差发电阵列12围成的炉膛或灶膛，在其合适位置分别设置炉灶门3，方便添加燃料；下层为储灰室5，用于出渣，同时具备进气功能，使燃烧更充分。As shown in Figure 1-3, a firewood stove with temperature difference power generation is assumed to be a cube, the uppermost part is a table top 1, and the lower part is a stove body 2. The stove body 2 is made of a metal shell, which plays the role of mechanical fixation, mechanical support and electrical support. Safety grounding function. The stove body consists of upper and lower layers, separated by a metal filter screen 4 in the middle. The upper layer is a hearth or hearth surrounded by a heat transfer metal plate 11 and a thermoelectric power generation array 12. A stove door 3 is respectively arranged at its appropriate position to facilitate fuel addition; the lower layer It is the ash storage chamber 5, which is used for slag removal, and has the function of air intake to make the combustion more complete.
温差发电片环形紧贴于传热金属板11的内层，温差发电片之间的间隙填充绝热材料10。根据不同输出电压，如3.6、5、12V和24V的直流电能的需要，由若干个发电片通过级联、串联和并联的形式电气上连在一起，形成温差发电阵列12，通过导线将温差发电阵列12与金属外壳2上的第一直流电源插座6、 第二直流电源插座7及内置的蓄电池8连在一起。The thermoelectric generation sheets are annularly attached to the inner layer of the heat transfer metal plate 11 , and the gaps between the thermoelectric generation sheets are filled with the heat insulating material 10 . According to the needs of DC power of different output voltages, such as 3.6, 5, 12V and 24V, several power generation chips are electrically connected together in the form of cascading, series and parallel to form a thermoelectric power generation array 12, and the temperature difference power is generated through wires. The array 12 is connected with the first DC power socket 6 on the metal casing 2 , the second DC power socket 7 and the built-in storage battery 8 .
根据不同的需要，温差发电阵列12和炉灶金属外壳2之间，可以设置冷却层9，用冷却材料如冷却水管等来强制拉低冷端，即外壳温度，这样就可以提供家用热水，并进一步提高发电效率和热量利用率。According to different needs, between the thermoelectric power generation array 12 and the stove metal casing 2, a cooling layer 9 can be set, and cooling materials such as cooling water pipes, etc. can be used to forcibly lower the cold end, that is, the temperature of the casing, so that domestic hot water can be provided, and Further improve power generation efficiency and heat utilization.
发电原理是：多个温差发电片通过级联、串联和并联的形式组成温差发电阵列；发电阵列的热端配有传热金属板，冷端紧贴炉灶的金属外壳。当炉膛、灶膛内有燃料燃烧时，炉灶内外的温差作用在发电阵列上，由于温差发电片的赛贝克效应将高温端与低温端温差产生的热能转化为直流电能输出。The principle of power generation is: multiple thermoelectric power generation sheets are connected in cascade, series and parallel to form a thermoelectric power generation array; the hot end of the power generation array is equipped with a heat transfer metal plate, and the cold end is close to the metal shell of the stove. When there is fuel burning in the furnace and the furnace, the temperature difference between the inside and outside of the furnace acts on the power generation array. Due to the Seebeck effect of the thermoelectric power generation sheet, the heat energy generated by the temperature difference between the high temperature end and the low temperature end is converted into DC power output.
