Description

Technical Field

[0001] The invention relates to the technical field of electric energy, in particular to a temperature difference power generation power cooker. Background Art

[0002] Temperature difference power generation, also known as thermoelectric power generation, is a green and environmentally friendly way of power generation. Its basic principle is the Seebeck effect. Temperature difference power generation technology is a technology that uses thermal energy to directly generate electricity. Compared with traditional power generation methods, it has a series of advantages such as simple structure, durability, no moving parts, no noise during operation, no waste emissions, long service life, and high reliability. It is an environmentally friendly way of power generation. Thermoelectric power generation technology can directly convert various low-grade thermal energy such as solar energy, geothermal energy, and industrial waste heat into electrical energy. It is precisely because of the above advantages of temperature difference power generation that it has been widely used in aviation, military and other fields.

[0003] Some existing thermoelectric power generation devices mainly use hot water added to the container to generate electricity using the temperature difference between the hot water and the external environment. For example, Xi Tianjing introduced a thermoelectric power generation cup in his patent "Thermoelectric Power Generation Cup". By pouring hot water into the cup and generating electricity using the temperature difference between the inside and outside of the cup, the process of converting thermal energy into electrical energy can be intuitively reflected. It is mainly used in teaching activities to enable students to have a better understanding of the conversion of thermal energy and electrical energy. Tian Haijin designed a thermoelectric power generation cup in "Hot Water Cup that Can Generate Electricity" that uses the low-grade dissipated thermal energy of drinking cups in daily life, with high power generation efficiency and stable performance, so that ordinary cups have the functions of drinking water, generating electricity, listening to music, lighting, etc., and are environmentally friendly, energy-saving, hygienic, and pollution-free. These two methods use water temperature to generate electricity, but because the temperature of hot water will not exceed 100°C, this power generation method cannot obtain a larger temperature difference, the power generation power is relatively small, and the power generation is insufficient in harsh environments such as the wild.

[0004] Therefore, in view of the problems existing in the prior art, it is particularly important to provide a temperature difference power generation device with simple structure, large power generation capacity, high heating efficiency, energy saving and environmental protection.

[0032] In order to make the purpose, technical solutions and advantages of the invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Example 1

[0035] The thermoelectric power cooker of the present invention can realize the direct conversion of heat generated by combustion or other external heat into electrical energy, can generate electricity while heating food, and can effectively store and transform the generated heat with the aid of voltage stabilization and energy storage devices; the use of multi-stage thermoelectric power generation modules 3 can improve efficiency, and at the same time can ensure that the temperature of the two hot ends of the thermopile is uniform; the power cooker has a simple structure, is easy to carry and use, and is energy-saving and environmentally friendly. The heat source of the power cooker can be photothermal power generation, or it can use the temperature difference in the environment to generate electricity. It is more universally applicable than solar photovoltaic power generation, has no carbon emissions, and is environmentally friendly.

[0036] Among them, the multi-stage cascade temperature difference power generation module 3 includes a third-stage thermoelectric sheet, a second flat plate heat pipe, a second-stage thermoelectric sheet, a first flat plate heat pipe, and a first-stage thermoelectric sheet stacked in sequence. The use of multi-layer cascades can improve efficiency. The heating or insulation part can include a temperature equalizer, the purpose of which is to make the temperature of the hot end 2 surfaces of the thermopile uniform. The temperature equalizer can adopt three structures: a flat plate heat pipe, a heat pipe cold plate, or a heat storage body. Compatible materials, under optimized working temperature conditions; a three-stage stacked thermoelectric pile, with a flat plate heat pipe arranged between every two stages. Assuming that the temperature of the hot end 2 is 700 degrees Celsius and the temperature difference of each thermoelectric sheet is 200 degrees Celsius, the first flat plate heat pipe and the second flat plate heat pipe need to work at 500 degrees Celsius and 300 degrees Celsius, respectively.

[0037] The pot body 8 is provided with an interlayer, and the interlayer is provided with a heat insulating filler 10. The heat insulating filler 10 ensures that the outside of the pot body 8 is not hot, and the heat inside the pot body 8 does not lose, which is safe and reliable. The thickness of the heat insulating filler 10 can be set to one inch thick according to the specific situation.

[0038] The power output interface 7 includes a USB interface, and multiple other interfaces can also be provided, which are specifically designed according to needs. A lighting lamp or other equipment that needs power supply can be installed on the power output interface 7, which is highly practical.

[0039] The voltage-stabilizing energy storage module in the electrical assembly box 6 is a supercapacitor battery. The supercapacitor battery is a new type of energy storage device, which has a short charging time, a long service life, good temperature characteristics, energy saving and green environmental protection.

The features not explained in this embodiment adopt the explanation of embodiment 1 and will not be repeated here. The difference between this embodiment and embodiment 1 is that: the heating surface of the hot end 2 is a curved spherical crown heating surface 1. Furthermore, the spherical crown heating surface 1 is coated with a nano heat-absorbing coating. Designing the heating surface as a curved spherical crown heating surface 1 can improve the efficiency of the hot end 2, and the nano heat-absorbing coating further improves the heating effect. This design ensures that the power pot has good heat collection performance.

Furthermore, the heat dissipation protrusions in the heat dissipation protrusion array 5 are needle-shaped and extend upward from the bottom wall of the pot body 8. The needle-shaped protrusions can fully increase the contact area of ​​the cold end 4, and the mixture of water and water vapor can be effectively cooled quickly, and the temperature balance is effective.

[0045] Furthermore, the water inlet is provided with a filter membrane 9 for filtering particles. The filter membrane 9 can filter particles, but can allow water and water vapor to pass through, which can ensure the cleanliness of the cold end 4 and improve the cooling efficiency of the cold end 4.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
