Technical Field

[0001] The present invention relates to the technical field of temperature difference power generation, and in particular to a temperature difference generator and a burner thereof. Background Art

[0002] The fields of Internet of Things and computers mostly involve the use of some low-power communication infrastructure. These devices are mostly powered by UPS power supplies and other different models and types of power supplies. However, these power supply devices mostly play the role of voltage stabilization and power level conversion. When there is a temporary abnormality in the city power or industrial power consumption and it is impossible to store power for the corresponding equipment and facilities in time, a backup power supply is required. The main power supply and the backup power supply jointly power the equipment and facilities, which occupies a large volume and has a high cost. Summary of the invention

[0008] Optionally, a supporting member is further included, and the supporting member is provided at the opening of the peripheral edge, and a fuel inlet is provided on the supporting member. The fuel inlet provided on the supporting member is convenient for docking the container loaded with fuel with the fuel inlet, and can stably and continuously introduce fuel into the cover body, and is also convenient for fixing the container loaded with fuel, so that the overall volume of the burner can be small and the space occupied can be small.

[0016] Optionally, the controller includes a plurality of voltage stabilizing modules arranged in parallel or in series, and the thermoelectric generator is connected to the voltage stabilizing modules. The voltage stabilizing modules are used to stably output the electric energy converted by the thermoelectric generator into electric energy of corresponding voltage level, so that they can be connected in parallel or in series, thereby outputting stable electric energy for use by electrical equipment.

[0017] Optionally, the radiator includes a heat dissipation base and a plurality of heat dissipation fins uniformly arranged on the heat dissipation base.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Example 1

[0033] Combined with Figure 1-5 A burner comprises two cover bodies 1 connected together, wherein a peripheral edge 107 is provided around the cover body 1; a fuel inlet 101 is provided on the peripheral edge 107, and an outlet is provided on the peripheral edge 107 away from the fuel inlet 101; on both sides of a first combustion chamber 1052 formed between the fuel inlet 101 and the outlet, a plurality of partition pieces 105 which are not in contact with the peripheral edge 107 are evenly provided on the cover body 1; a second combustion chamber 1051 is formed between adjacent partition pieces 105; and a third combustion chamber 1053 is formed between a plurality of partition pieces 105 and the peripheral edge 107.

[0034] Two connected cover bodies 1 are combined to form the burner. The fuel enters the first combustion chamber 1052, the second combustion chamber 1051 and the third combustion chamber 1053 in the cover body 1 from the fuel inlet 101 for stable combustion. The first combustion chamber 1052, the second combustion chamber 1051 and the third combustion chamber 1053 can, on the one hand, divert the fuel so that the fuel burns fully, and on the other hand, control the flame of the fuel to achieve a stable combustion effect. Continuous and stable combustion generates continuous and stable heat, providing a stable heat source for the temperature difference power generation sheet 2. There is no need to worry about abnormal situations such as power outages, and it takes up little space, does not need to be equipped with a backup power supply, and has low cost.

[0035] An optional implementation of this embodiment is that it further includes a supporting member 102, which is arranged at the opening of the surrounding edge 107, and a fuel inlet 101 is arranged on the supporting member 102. The fuel inlet 101 arranged on the supporting member 102, on the one hand, facilitates the docking of the container loaded with fuel with the fuel inlet 101, and can stably and continuously introduce fuel into the cover body 1, and on the other hand, it is also convenient to fix the container loaded with fuel; the overall volume of the burner can be small and the space occupied is small.

[0036] As one of the optional implementations of this embodiment, a metal mesh 108 is provided between the support member 102 and the surrounding edge 107. On the one hand, the metal mesh 108 plays a role of natural suction and provides sufficient air for fuel combustion; on the other hand, the metal mesh 108 is designed with a suitable aperture size to prevent backfire and ensure that the flame does not escape to the outside of the burner, so that the heat generated by the fuel combustion is fully absorbed and utilized, reducing heat loss. The aperture selection of the metal mesh 108 can be determined comprehensively by considering factors such as the total heat output value of the burner, the fuel supply, the size of the combustion chamber, the structural size of the cover body 1, etc. The specific aperture value can be determined according to actual needs.

[0037] Optional implementation methods during specific implementation, combined with Figure 1 , 3, 4 and 5, the metal mesh 108 is symmetrically arranged on both sides of the support member 102, between the support member 102 and the surrounding edge 107, and the support member 102 and the surrounding edge 107 are both provided with a snap-fit ​​position 1081 for fixing the metal mesh 108, so that the metal mesh 108 is arranged between the support member 102 and the surrounding edge 107, which plays a role in natural air suction and preventing backfire. An optional implementation is that the snap-fit ​​position 1081 can be a strip groove that can be inserted into the side of the metal mesh 108, or can be a fixing hole provided on the support member 102 and the surrounding edge 107, and the side of the metal mesh 108 is fixed to the support member 102 and the surrounding edge 107 by screws and other fixing parts through the fixing holes on the support member 102 and the surrounding edge 107. As an optional implementation of this embodiment, if a single-layer metal mesh 108 cannot achieve a good effect of preventing tempering, the metal mesh 108 can be arranged in multiple layers.

[0038] As an optional implementation of this embodiment, a fuel inlet 101 is provided on the surrounding edge 107, and an outlet is provided on the surrounding edge 107 away from the fuel inlet 101. To ensure sufficient combustion of the fuel, it is necessary to provide sufficient combustion space for the combustion of the fuel, such as Figure 1 , 3 -5, if the structure of the cover body 1 is square, when the fuel inlet 101 is located at one diagonal position of the square cover body 1, the outlet is located at another diagonal position, so as to ensure that there is enough space on the cover body 1 to form a space for the fuel to be fully burned, that is, the first combustion chamber 1052, the second combustion chamber 1051 and the third combustion chamber 1053. In this way, the fuel is fully burned and more heat is generated for the thermoelectric generator to generate electricity.

[0039] An optional implementation of this embodiment is that a plurality of fixing members 106 are provided outside the surrounding edge 107. The fixing members 106 are used to fix the burner at a specified position, and a plurality of fixing holes 1061 are provided on the fixing members 106 to facilitate connection of similar connecting members such as screws, bolts or bolts with the burner.

[0040] Example 2

[0041] Combined with Figure 1-5Compared with the technical solution of Example 1, a burner of this embodiment further includes a first stopper 103, which is located at the support member 102 and directly faces the fuel inlet 101. The first stopper 103 divides the fuel entering through the fuel inlet 101 into two streams located on both sides of the first stopper 103, and flows to the third combustion chamber 1053 located on both sides of the first stopper 103 respectively; the fuel after diversion by the first stopper 103 merges in the first combustion chamber 1052, and flows to a plurality of second combustion chambers 1051 located on both sides of the first combustion chamber 1052 respectively through the first combustion chamber 1052; the exhaust gas after combustion converges to the outlet through the third combustion chamber 1053. Through the first stopper 103 and the first combustion chamber 1052, the second combustion chamber 1051 and the third combustion chamber 1053, the effects of diversion, stable combustion and full combustion are achieved.

[0042] An optional implementation of this embodiment is to further include a second stopper 104 disposed at the outlet. The second stopper 104 plays a buffering role. Due to the temperature difference between the inside and outside of the burner, the exhaust gas after combustion has a certain impact force and potential energy. After the exhaust gas after combustion is blocked by the second stopper 104, the impact potential energy of the exhaust gas itself is reduced, and the exhaust gas can be discharged to the outside of the burner at a relatively gentle speed to eliminate the potential safety hazards of the burner itself.

[0043] An optional implementation of this embodiment is that the adjacent partitions 105 located on the same side of the first combustion chamber 1052 stand in parallel to form a second combustion chamber 1051 with a relatively regular shape, so as to achieve the effects of stable combustion, diversion and full combustion of the fuel.

[0044] Example 3

[0045] Combined with Figure 1-5 , a burner of this embodiment, compared with the technical solution of embodiment 1 or 2, the end of the partition 105 away from the surrounding edge 107 is provided with an inclined end surface 1054 to form the first combustion chamber 1052 of the strip-shaped channel. The first combustion chamber 1052 of the strip-shaped channel can reduce the resistance of the fuel during the flow process, and facilitate the unimpeded flow, combustion, diversion and full combustion of the fuel in the set first combustion chamber 1052, the second combustion chamber 1051 and the third combustion chamber 1053.

[0046] An optional embodiment is that the outer shape of the cover body 1 can be a quadrilateral, a triangle, a polygon, etc. Figure 1-5As shown in , as one of the optional implementations of this embodiment, the outer shape of the cover body 1 is a square, the surrounding edge 107 is arranged on the cover body 1, the support member 102 and the outlet are respectively located at the diagonal positions of the square cover body 1, and the first combustion chamber 1052 is arranged along the diagonal line connecting the support member 102 and the diagonal position of the outlet. The reason why the first combustion chamber 1052 is arranged at the diagonal position is to maximize the length of the first combustion chamber 1052, as well as the space occupied by the second combustion chamber 1051 and the third combustion chamber 1053, and also to achieve stable combustion, diversion and full combustion.

[0047] The partition pieces 105 located on both sides of the first combustion chamber 1052 run along the first combustion chamber 1052 and stand parallel to the surrounding edge 107 to form a plurality of second combustion chambers 1051 and a third combustion chamber 1053 between the partition pieces 105 and the surrounding edge 107 .

[0048] Example 4

[0049] Combined with Figure 1-5 A thermoelectric generator of this embodiment includes a burner described in any one of the technical solutions of embodiments 1-3 and a combination thereof without any contradiction. A thermoelectric power generation sheet 2 and a heat sink 3 are provided on the outer side of the cover body 1 in sequence, and the thermoelectric power generation sheet 2 is electrically connected to the controller.

[0050] The thermoelectric generator sheet 2 is closely arranged on the outside of the cover body 1, and can fully absorb the heat of the cover body 1. The thermoelectric generator sheet 2 is used to absorb the heat conducted on the cover body 1 and convert it into electrical energy, and then transmit it to the controller; the radiator 3 is used to dissipate heat for the thermoelectric generator sheet 2; an optional implementation method of this embodiment is that the radiator 3 is a liquid cooling module. By controlling the electrical connection mode between a plurality of thermoelectric generator sheets 2 and the controller, a plurality of thermoelectric generator sheets 2 can be connected in parallel or in series, so that the power level of the controller output electrical energy can be different. The thermoelectric generator sheet 2 is in contact with the cover body 1 over a large area to ensure uniform temperature; the fixing member 106 facilitates fixing the thermoelectric generator at the desired position.

[0051] An optional implementation of this embodiment is that the controller includes a plurality of voltage stabilizing modules arranged in parallel or in series, and the thermoelectric power generation sheet 2 is connected to the voltage stabilizing modules. The voltage stabilizing modules are used to stably output the electric energy converted by the thermoelectric power generation sheet 2 into electric energy of corresponding voltage level, so that they can be connected in parallel or in series, thereby outputting stable electric energy for use by electrical equipment.

[0052] An optional implementation is that the controller further includes a protection circuit for protecting the voltage stabilizing module. By setting up a protection circuit, damage to the voltage stabilizing module caused by abnormal changes in electric potential energy generated by the burner, the thermoelectric power generation sheet 2 or the heat sink 3 can be prevented, so as to protect the voltage stabilizing module, thereby ensuring the safety of the structural equipment at the rear end of the thermoelectric power generation sheet 2 and playing a timely and effective protection role.

[0053] An optional implementation of this embodiment is that the radiator 3 includes a heat dissipation base 301 and a plurality of heat dissipation fins 302 uniformly arranged on the heat dissipation base 301. The heat dissipation base 301 is arranged on the temperature difference power generation sheet 2, and adjacent heat dissipation fins 302 form a heat dissipation channel 303 to achieve heat dissipation.

The outer sides of the two cover bodies 1 are sequentially affixed with the thermoelectric power generation sheet 2 and the radiator 3 that match the shape of the cover body 1. That is: the two cover bodies 1 are covered together, and the thermoelectric power generation sheet 2 is installed outside the cover body 1, and the radiator 3 is installed outside the thermoelectric power generation sheet 2 for natural heat dissipation. The overall size of the thermoelectric generator is very small, with a thickness of only 2-3 cm. A fuel nozzle is installed at the fuel inlet 101, or it is docked with a container filled with fuel. The several cavities formed by the partition 105 inside the cover body 1 are responsible for stable combustion.

[0055] In an optional embodiment, when the cover 1 is a square, in order to adapt to the shape of the cover 1, the thermoelectric power generation sheet 2 and the heat sink 3 are both squares that match the shape of the cover 1. This embodiment can realize a micro thermoelectric generator with the following technical features, including but not limited to: (1) The burner formed by the leaf-shaped combustion cavity structure acts as a burner and a heat collector at the same time. (2) The heat sink 3 is used for natural convection heat dissipation, and it can generate electricity without any energy consumption. (3) The battery life is long, and a bottle of fuel weighing 450 grams can run continuously for a week. (4) The burner is self-breathing, and the micro-combustion process is self-breathing, and no energy is required to provide air. The thermoelectric generator described in the technical solution of this embodiment is used in the field of the Internet of Things, providing a little electricity for infrastructure such as various types of sensors; a can of fuel (10kg) can continuously supply power for more than 140 days, and unattended throughout the process.
