Detailed description of the invention
To develop simultaneously embodiment below in conjunction with accompanying drawing, the utility model is described in detail.
The utility model provides a kind of thermo-electric generation kettle, comprise kettle inner bag 2, kettle outer wall 3, kettle base 11, thermo-electric generation sheet 12, thermal component 8, voltage stabilizing energy storage and control module 7 and USB interface 5, wherein, comprise the central authorities that kettle thermo-electric generation sheet 12 is placed on kettle base 11, between kettle base 11 and inner bag 2, kettle outer wall 3 is positioned at the outside of kettle inner bag 2, kettle base 11 is connected with kettle inner bag 2 by set bolt 9, thermo-electric generation kettle base 11 is connected with kettle outer wall 3 by set bolt 10, thermal component 8 is positioned at the bottom of kettle inner bag 2, voltage stabilizing energy storage and control module 7 are arranged on kettle inner bag 2, and be connected with thermo-electric generation sheet 12, USB interface 5 is arranged on kettle outer wall 5, and is connected with control module 7 with voltage stabilizing energy storage, and kettle outer wall is also provided with venthole 6.
Kettle base is for isolating thermal source and heat transfer.The fire that thermal source due to this thermo-electric generation kettle produces when being and using timber or fuel to heat up water, and the temperature of fire is very high, such as, the temperature of household gas cooker is about 300 DEG C, during alcolhol burner burning, the temperature of flame envelope can reach 600 DEG C, temperature during combustion of wood generally also can to 600 DEG C, and the maximum temperature that thermoelectric generator hot junction can be born generally is no more than 300 DEG C.Therefore, need higher ignition temperature and thermoelectric generator hot junction to isolate, and ensure that thermal conductivity is better.The utility model adopts the metal material with better thermal conductivity (more than 100W/mK), as aluminium alloy or copper etc., make the kettle base that has certain thickness (thickness of base should ensure can not burn out generating sheet), realize burning things which may cause a fire disaster and the isolation of thermo-electric generation sheet and effective conduction of heat.Because flare can wave with surrounding environment, therefore being heated of kettle base when heating up water can be caused to be uneven, it is random for can thinking that the heat of a certain moment kettle base distributes, and during the work of thermo-electric generation sheet, the distribution of its hot-side temperature should keep even as far as possible.Found by simulation analysis, the heat conductivility due to aluminum alloy materials will be much better than the heat conductivility of air, and heat can preferentially be conducted by aluminum alloy materials.Therefore adopt mode as shown in Figure 2 to carry out the design of kettle base, kettle base 11 is the middle disk with square projection, and one-body molded, wherein, intermediate raised portion is called thermo-electric generation base 13, and remainder is called bottom of water kettle 14.The thickness of kettle base is a very important factor, and the too thick meeting of base causes rate of heat transfer slow, and affect thermo-electric generation effect, base is too thin, and the sheet that can cause generating electricity burns out.By adopting Ansys thermal analyses and actual test to find, when the thickness of base is greater than 2 millimeters, just can the safe operation more than 15 minutes when alcolhol burner is thermal source, and water is boiled.Therefore, the thickness of thermoelectric generator base 13 and bottom of water kettle 14 is respectively 1.5 millimeters and 1 millimeter, and thermo-electric generation sheet 12 is placed on thermoelectric generator base 13.
Thermo-electric generation sheet is the core component of temperature difference electricity generation device, the Seebeck coefficient of its generated output and generating efficiency and material therefor is closely related, the mean value of the general thermocouple plug seebeck coefficient be made up of simple metal is about 20 μ V/K, the thermocouple be made up of alloy material, Seebeck coefficient mean value is about 50 μ V/K, and for semi-conducting material, Seebeck coefficient can reach 1000 μ V/K, and the thermo-electric generation sheet of the semi-conducting material that Seebeck coefficient is higher therefore should be selected as thermo-electric generation sheet of the present utility model.Found by inspection information, Bi

3the semiconductor generator part that material is made, the utility model selects commercial power generating device TEHP1-24156-1.2 as the thermo-electric generation sheet of temperature difference electricity generation device, and the performance parameter of TEHP1-24156-1.2 is as shown in table 1:
Table 1TEHP1-24156-1.2 performance parameter
Kettle inner bag is mainly used to deposit water, is connected, absorbs heat by water bottom it with the cold junction of thermo-electric generation sheet, reduces the cold junction temperature of generating sheet, keeps the temperature difference in two faces of thermoelectric generator.In order to the heat transfer effect obtained, the bottom of kettle inner bag should expand the contact area with water as far as possible, and for this reason, the utility model installs dentation thermal component 8 as shown in Figure 3 in the bottom of kettle inner bag 2, thermal component 8 material selection heat conductivility is better, the aluminum alloy materials that density is lighter simultaneously.Simultaneously in order to place voltage stabilizing energy storage and control module 7, cave inward in the middle part of kettle inner bag, reserved the space of a cuboid, for fixed placement voltage stabilizing energy storage and control module 7, there is bolt 9 bottom of kettle inner bag 2 for being connected with kettle base 11 by inner bag 2 simultaneously.
Kettle base, thermo-electric generation sheet and kettle inner bag are fixed up by kettle outer wall, make it into as a whole.Durable in order to ensure thermo-electric generation kettle, kettle outer wall adopts material such as the aluminum alloy materials with certain degree of hardness to make, fill with hard class heat-insulating heat-preserving material or soft class heat-insulating heat-preserving material such as reflecting heat insulation paint ZS-211 between kettle outer wall 3 and kettle inner bag 2 simultaneously, in order to avoid the heat that base 11 absorbs is directly passed to kettle inner bag 2, impact generating effect.
Kettle outer wall 3 can one-body moldedly directly be enclosed within kettle inner bag, or is made up of left and right two parts, and left-right parts is connected by fixed part 16, and kettle outer wall 3 is connected by set bolt 10 with kettle base 11.
Kettle outer wall 3 is provided with temperature indicator 4 and USB interface 5, and temperature indicator 4 is connected with control module with voltage stabilizing energy storage with USB interface 5, is used to refer to the temperature of water in kettle and exports the stable electric energy produced.
In addition, because kettle is when heating up water, the air in the gap between its kettle inner bag 2 and kettle outer wall 3 can be heated to very high temperature, and volume can significantly expand, and therefore, kettle outer wall 3 is provided with venthole 6, to avoid danger.
