[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0050] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the present invention provides a portable modular outdoor emergency power generation device, which mainly forms a heat convergence space 3 in the heat storage cabin 1, and combines the three-dimensional cabin structure characteristics of the heat storage cabin 1 to conduct heat out from different three-dimensional directions.

[0051] The three-dimensional cabin structure characteristics of the heat storage cabin 1 can not only improve the heat convergence effect, but also ensure the effective conduction and conversion of heat. The portable modular outdoor emergency power generation device provided by the present invention completes thermoelectric conversion from multiple three-dimensional directions of the heat collection position, with a high degree of heat collection, enhanced heat conduction effect, improved thermoelectric conversion efficiency, and at the same time solves the problem that it may be difficult to start a fire outdoors and no heat source can be provided.

[0052] The portable modular outdoor emergency power generation device provided by the present invention includes a heat storage cabin 1 with an opening, and a heat source module 2 is arranged in the direction directly facing the opening of the heat storage cabin 1, and the heat source module 2 transfers heat into the heat storage cabin 1.

[0053] A heat collection space is formed in the heat storage cabin 1, and heat conduction surfaces 4 are formed on different outer walls of the heat storage cabin 1, and a thermoelectric conversion structure 5 is installed on each heat conduction surface 4.

[0054] The thermoelectric conversion module is externally connected to a power supply device, and the power supply device can be a small storage battery. When the electrical equipment does not need power, the converted electrical energy can be directly stored in the storage battery, and when in use, the storage battery is used to supply power to the electrical equipment.

[0055] On two opposite surfaces of the thermoelectric conversion structure 5, a cold end 6 and a hot end 7 are respectively formed. The hot end 7 is docked with the outer wall of the heat storage cabin 1, and a heat dissipation module 8 is installed outside the cold end 6. The heat dissipation module 8 promotes the heat dissipation of the cold end 6, so as to generate a temperature difference between the cold end 6 and the hot end 7 of the thermoelectric conversion structure 5, and the thermoelectric conversion structure 5 generates electricity based on the temperature difference, converts heat energy into electrical energy, and then transmits the electrical energy to the power supply device.

[0056] In the present invention, not only is the heat conversion efficiency improved through three-dimensional multi-directional heat conduction and conversion at the hot end 7, but a heat dissipation module 8 is also installed at the cold end 6 to further increase the temperature difference and improve the heat conversion efficiency.

[0057] The heat source module 2 is used to supply heat to the heat storage chamber 1. The heat source module 2 can be a bonfire burning in the wild. Further, as Figure 4 shown, the heat source module 2 can be a heat supply structure that automatically burns to provide heat. Specifically, the heat source module 2 includes a gas tank 21 and a self-priming windproof burner 22 installed at the outlet of the gas tank 21. The inlet of the self-priming windproof burner 22 is docked with the outlet of the gas tank 21, and its outlet is directly opposite the opening of the heat storage chamber 1.

[0058] The gas tank 21 is filled with gas, and the gas is isobutane. As a hydrocarbon gas, isobutane has the characteristics of high energy density and low price, which can greatly reduce the cost of the entire device.

[0059] A gas valve is installed on the self-priming windproof burner 22, and the gas valve can be manually controlled to open and close. When the gas valve of the self-priming windproof burner 22 is opened, the gas sprays out from the gas tank 21 through the self-priming windproof burner 22. After ignition, a large amount of heat is generated by the combustion of isobutane, and the heat is sprayed onto the heat storage chamber 1 and converges in the heat convergence space 3 inside the heat storage chamber 1. The wall of the heat storage chamber 1 is made of a heat-conducting material, and the heat is conducted to different thermoelectric conversion structures 5 through different heat conduction surfaces 4 on the heat storage chamber 1.

[0060] Specifically, as Figure 7 shown, the self-priming windproof burner 22 includes a gas inlet pipe 221, an adjusting screw bolt 222, and a metal pipe 223;

[0061] The top of the gas inlet pipe 221 is connected to the metal pipe 223 and is in communication with the metal pipe 223. The top of the metal pipe 223 is directly opposite the opening of the heat storage chamber 1, and the gas inlet pipe 221 is docked with the outlet of the gas tank 21;

[0062] The adjusting screw bolt 222 is threadedly installed on the gas inlet pipe 221;

[0063] An air regulator is installed outside the metal pipe 223, and air enters the metal pipe 223 from the air regulator and mixes with the gas.

[0064] In the above embodiments, the gas enters the metal pipe 223 from the gas inlet pipe 221 and sprays out. Inside the metal pipe 223, the gas mixes with air. The adjusting screw bolt 222 can spiral horizontally on the gas inlet pipe 221. Here, the adjusting screw bolt 222 is equivalent to the gas valve for controlling the gas spraying process described above. The end of the adjusting screw bolt 222 can seal the gas inlet pipe 221 and can also adjust the cross-section of the gas passing through the gas inlet pipe 221 under movement, thereby controlling the output gas volume;

[0065] The air conditioner can also be designed as an air valve, which allows air to enter and controls the amount of air entering the metal pipe 223. The amounts of both the fuel gas and air can be controlled. Therefore, by controlling the amount of fuel gas and the control amount, the gas ratio can be adjusted, thereby further controlling the size of the flame.

[0066] Among them, as Figure 4 shown, an installation cabin 14 for accommodating the gas tank 21 is arranged in the direction directly facing the opening of the heat storage cabin 1. The installation cabin 14 has an upward opening and allows the self-priming windproof burner 22 to pass through. A hollow support frame 15 for installing the self-priming windproof burner 22 is installed on the installation cabin 14, and the heat storage cabin 1 is installed on the support frame 15.

[0067] The support frame 15 is the main body for supporting the heat storage cabin 1 and the heat dissipation module 8. The gas tank 21 is accommodated in the installation cabin 14. If the fuel gas in the gas tank 21 is exhausted, it can also be taken out and ignited with an open flame to provide heat for the heat storage cabin 1.

[0068] As a preferred implementation of the present invention, the heat storage cabin 1 can be a cuboid structure. Heat conduction surfaces 4 are formed on four side surfaces of the cuboid structure, and thermoelectric conversion structures 5 are installed on the four heat conduction surfaces 4. The heat storage cabin 1 can also be other polyhedron structures, and the area of the heat conduction surfaces 4 of the polyhedron structure preferably fits the hot ends 7 of the thermoelectric conversion structures 5. That is to say, under the condition that the hot ends 7 of the thermoelectric conversion structures 5 are in full contact with the heat conduction surfaces 4 of the polyhedron structure, the number of surfaces of the polyhedron structure is as large as possible, so as to improve the heat utilization rate.

[0069] In addition, it is also necessary to consider whether there is interference between the installation areas of the heat dissipation modules 8, and based on this, determine the number and corresponding shapes of the heat conduction surfaces 4 of the polyhedron structure.

[0070] To improve the heat conduction rate between the heat conduction surface and the thermoelectric conversion structure 5, it is necessary to make: a layer fitting the heat conduction surface 4 is formed on the side of the second heat conduction layer 53 away from the conductive layer 52, that is to say, the hot end 7 fits the heat conduction surface 4.

[0071] Among them, the thermoelectric conversion structures 5 are installed on different heat conduction surfaces 4. As Figure 5 shown, the thermoelectric conversion structure 5 includes a first heat conduction layer 51, a conductive layer 52, and a second heat conduction layer 53 arranged in sequence. The cold end 6 is arranged on the side of the first heat conduction layer 51 away from the conductive layer 52, and the hot end 7 is arranged on the side of the second heat conduction layer 53 away from the conductive layer 52.

[0072] Both the first heat-conducting layer 51 and the second heat-conducting layer 53 are made of heat-conducting materials. The first heat-conducting layer 51 and the second heat-conducting layer 53 can be ceramic laminates made of alumina. The conductive layer 52 is composed of a conductive material and can be a conductive layer 52 plate made of bismuth telluride.

[0073] Among them, the thickness of the first heat-conducting layer 51 and the second heat-conducting layer 53 on both sides is 1 mm, and the thermal conductivity is 30 W / (m·K). The thickness of the middle conductive layer 52 is 2 mm, and the thermal conductivity is 1.6 W / (m·K). The cross-sectional area of a single particle is 1*1 mm 2 .

[0074] The conductive layer 52 is externally connected with a wire 16 and is externally connected with a power supply device through the wire 16. The conductive layer 52 can transmit electric energy through the wire 16.

[0075] The first heat-conducting layer 51 and the second heat-conducting layer 53 completely cover the conductive layer 52 to ensure that the temperature is conducted to all areas of the conductive layer 52.

[0076] The conductive layer 52 includes a p-type semiconductor 521 and an n-type semiconductor 522. A conductive sheet 523 is provided between the two ends of each pair of the p-type semiconductor 521 and the n-type semiconductor 522. The p-type semiconductor 521 and the n-type semiconductor 522 are connected through the conductive sheet 523. The conductive sheet 523 is arranged inside the first heat-conducting layer 51 and the second heat-conducting layer 53, and the wire 16 is connected to the conductive sheet 523.

[0077] The thermoelectric power generation sheet is composed of the first heat-conducting layer 51, the conductive layer 52, and the second heat-conducting layer 53. The thermoelectric conductive sheet 523 utilizes the Seebeck effect. When there is a temperature difference between the two ends of the thermoelectric power generation sheet, the carriers inside it move from the hot end 7 to the cold end 6 and accumulate at the cold end 6 to form an electric potential difference. When the charge flow of the thermal motion and the internal electric field reach dynamic equilibrium, a stable thermoelectric electromotive force is formed at both ends of the thermoelectric power generation sheet, thereby converting thermal energy into electric energy. The thermoelectric power generation sheet is connected to the power supply device through the wire 16 and can stably provide voltage. The greater the temperature difference between the cold end 6 and the hot end 7 of the thermoelectric power generation sheet, the more electric energy it can provide.

[0078] The above describes the structure of the hot end 7 of the thermoelectric conductive sheet 523 and the structure and principle of the thermoelectric conductive sheet 523 itself. At the cold end 6 of the thermoelectric conductive sheet 523, the corresponding temperature is achieved through the heat dissipation module 8. Specifically, such as Figure 1 、 Figure 2 and Figure 4 、 Figure 6As shown in the figure, the heat dissipation module 8 includes a heat dissipation base 81, a heat pipe 82 passing through the heat dissipation base 81, and a plurality of heat sinks 83 mounted on the heat pipe 82. The heat pipe 82 is filled with liquid. Both ends of the heat pipe 82 extend out of the heat dissipation base 81 and are symmetrically arranged on both sides of the heat dissipation base 81. The thermoelectric conversion structure 5 is arranged in the heat dissipation base 81, and the pipe section of the heat pipe 82 located in the heat dissipation base 81 abuts against the outer wall of the cold end 6;

[0079] A heat dissipation fan is installed outside the heat sink 83. The air outlet of the heat dissipation fan faces the heat sink 83, and the direction of the heat sink 83 is set along the air outlet direction of the heat dissipation fan.

[0080] Assume that there are two sections of the heat pipe 82, namely a central pipe section and an end pipe section. The end pipe section is arranged at the end of the central pipe section. The central pipe section is arranged in the heat dissipation base 81, and the central pipe section abuts against the outer wall of the cold end 6.

[0081] The heat dissipation fan can reduce the surrounding environmental temperature to a certain extent through forced convection on the basis of natural air convection. It is heated at the central pipe section, and the liquid in the central pipe section vaporizes. When the vapor drifts to the end pipe section area, it is cooled by the heat sink 83 and the heat dissipation fan and then condenses back into liquid and flows back. The cooling medium in the heat pipe 82 evaporates at the central pipe section and condenses at the end pipe section through capillary action or gravity, and circulates repeatedly, which can better achieve the heat dissipation effect and keep the temperature of the cold end 6 facing the central pipe section at a lower level.

[0082] When the heat source is certain, the greater the temperature difference, the greater the heat dissipation power required for the heat dissipation module 8. For example, a heat dissipation power of 390 watts is required to generate a temperature difference of 170 degrees. Therefore, the quality of the heat dissipation module 8 determines the level of the output voltage.

[0083] As a preferred embodiment of the present invention, assume that the heat storage chamber 1 is a cuboid structure, the central pipe section is arranged vertically, the end pipe section is arranged horizontally, and the number of symmetrically arranged heat sinks 83 is the same and corresponds one by one, which makes the gaps between the heat sinks 83 align one by one. In this way, the heat dissipation fan can blow air along the gaps between the heat sinks 83 to cool the heat pipe 82 at the same time.

[0084] The heat dissipation base 81 needs to be installed on the outer wall of the heat storage chamber 1, that is, on the heat conduction surface 4. Specifically, as Figure 1 and Figure 3 shown, symmetric clamping strips 10 are provided on the outer wall of the heat storage chamber 1. The heat dissipation base 81 is installed between the clamping strips 10, and a bending portion 11 is formed on the clamping strips 10. The bending portion 11 limits the heat dissipation base 81 between the clamping strips 10.

[0085] A support platform 12 facing the heat sink 83 is provided on the outer wall of the heat storage chamber 1. A support plate 13 is arranged on the support platform 12 along the direction of the heat sink 83. The support plate 13 passes through the heat pipes 82 at adjacent positions and sequentially connects the heat sinks 83 at symmetric positions. The support plate 13 is fixedly connected to the heat sink 83 and the support platform 12 without interfering with the heat pipes 82.

[0086] The support plate 13 can support the heat sink 83, thereby installing and fixing the heat pipe 82. The overall installation and positioning of the heat dissipation module 8 are realized through the support platform 12 and the support plate 13.

[0087] To improve the heat conductivity between the heat dissipation module 8 and the thermoelectric conversion module, and between the heat storage chamber 1 and the thermoelectric conversion module, thermal conductive silicone grease can be evenly applied between the heat storage chamber 1 and the hot end 7 of the thermoelectric power generation chip, and between the heat pipe 82 of the heat dissipation module 8 and the cold end 6 of the thermoelectric power generation chip, so as to minimize heat loss and improve the heat conductivity.

[0088] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
