[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] The technical solutions provided by the embodiments of this utility model are described below with reference to the accompanying drawings.

[0037] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6An embodiment of this utility model provides a stove with a heat convection device, including a stove body 100. A heat convection mechanism 200 is provided on the outer wall of the stove body 100. The heat convection mechanism 200 includes a radiator 210. One end of the radiator 210 is provided with a plurality of fins 220. Preferably, the fins 220 can be designed to be wavy or serrated to enhance the turbulence effect. The ends of the fins 220 abut against the outer wall of the stove body 100. The fins 220 absorb heat from the surface of the stove body 100 through heat conduction and heat radiation, which can realize heat conduction between the two. A gas flow groove 230 is provided between two adjacent fins 220.

[0038] Please see Figure 4 , Figure 5 , Figure 6 and Figure 7 Specifically, the fins 220 can be made of metal (such as iron, copper, or alloy steel) or high thermal conductivity composite materials (such as graphene-coated aluminum) to improve heat transfer efficiency. Multiple fins 220 are arranged in parallel with a fin spacing of ≤5mm to form a vertical through channel (i.e., gas flow channel 230). The natural convection effect is enhanced through the vertical channel, and the heat exchange area is increased through dense arrangement. In addition, the height of the fins 220 is set to be basically the same as the height of the furnace body. The fins 220 surround the surface of the furnace body, with the bottom connected to the furnace body for thermal conduction and the top extending to the upper part of the furnace body, so as to fully absorb the heat of the outer wall of the furnace body.

[0039] Low-temperature air around the furnace body 100 enters the gas flow channel 230 from the bottom of the radiator 210. The low-temperature air is heated by the heat radiation generated by the fins 220 and the furnace body 100 in the gas flow channel 230, and its temperature rises. The temperature rises and the density of the low-temperature air decreases. The air flows autonomously due to the difference in fluid density, and then flows upward along the gas flow channel 230. It does not require external force to drive it. The natural convection circulation does not require additional energy and has no mechanical moving parts, thus eliminating noise. Then it is discharged from the upper outlet of the gas flow channel 230, forming a self-sustaining circulation, which heats the air around the furnace body 100.

[0040] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The furnace body 100 and the heat convection mechanism 200 can be directly fixed together by welding. Preferably, the heat convection mechanism 200 is detachably fixed to the furnace body 100 by a connecting mechanism 300. Specifically, the connecting mechanism 300 includes a first connecting part 310, which is fixed to both sides of the radiator 210. A connecting bolt 320 is inserted into the first connecting part 310, and a second connecting part 330 is screwed to the end of the connecting bolt 320. The second connecting part 330 is fixed to the furnace body 100. When installing the heat convection mechanism 200, firstly, the heat convection mechanism 200 is brought close to the outer wall of the furnace body 100. Then, the first connecting parts 310 on both sides of the heat convection mechanism 200 and the second connecting parts 330 on the furnace body 100 are roughly aligned. Then, the connecting bolt 320 is passed through the first connecting part 310. A through hole is provided on the first connecting part 310, and the nut on the connecting bolt 320 is located on the outside of the first connecting part 310. Then the connecting bolt 320 and the threaded hole on the second connecting part 330 are screwed together. Rotating the connecting bolt 320 causes it to move inward along the threaded hole on the second connecting part 330. The nut on the connecting bolt 320 pushes the first connecting part 310 inward, and the first connecting part 310 drives the radiator 210 to move towards the outer wall of the furnace body 100 until the fins 220 on the radiator 210 and the outer wall of the furnace body 100 are tightly abutted. The radiator 210 stops moving. Then the connecting bolt 320 is locked to fix the heat convection mechanism 200. When disassembling, the heat convection mechanism 200 can be separated from the furnace body 100 by rotating the connecting bolt 320 in the opposite direction.

[0041] Please see Figure 8 and Figure 9 The connecting mechanism 300 can also be a buckle 340. The buckle 340 is detachable. Buckles 340 are provided on both sides of the radiator 210. After the radiator 210 abuts against the outer wall of the furnace body 100, the heat convection mechanism 200 can be fixed to the furnace body 100 by locking the buckles 340 on both sides. The heat convection mechanism 200 can be separated from the furnace body 100 by releasing the buckles 340. It should be noted that, in addition to the above structure, any structure that can realize the quick installation and separation of the heat convection mechanism 200 from the furnace body 100 is within the protection scope of this application.

[0042] Please see Figure 1 , Figure 4 and Figure 10In addition, the heat convection mechanism 200 is set on one, two, three or four sides of the furnace body 100. The specific installation position, quantity, specifications and model of the heat convection mechanism 200 are selected according to the structure of the furnace body 100. This is common knowledge to those skilled in the art and will not be described in detail here. The fins 220 cover the furnace body surface to avoid direct contact between the human body and the high temperature area, reducing the risk of burns and greatly improving safety. Moreover, the radiator 210 can adopt a modular design to adapt to various furnace body sizes, greatly improving mobility and flexibility.
