[0026] An annular space 51 is provided between the inner wall of the outer box body 5 and the annular partition 4, and an air hole group 43 is also provided on the annular partition 4. The annular space 51 is connected to the first chamber 41 and the second chamber 42 through the air hole group 43; it can be understood that the annular space 51 is arranged around the accommodating space, and the annular partition 4 can be covered with the air hole group 43.
[0027] The air inlet connector 2 is connected to the first chamber 41 and / or the second chamber 42 , and the air outlet connector 3 is connected to the annular space 51 .
[0028] In the present invention, the part to be heated can be placed in the first chamber 41 or the second chamber 42. When the heating baffle 1 heats the part to be heated, the heating baffle 1 can heat the part to be heated by heat conduction and heat radiation. In addition, the air inlet connector 2 inputs gas into the first chamber 41 and / or the second chamber 42. After the gas circulates in the first chamber 41 and / or the second chamber 42, it flows into the annular space 51 through the air hole group 43. The gas in the annular space 51 finally flows out through the air outlet connector 3. In the process of the gas flowing in the first chamber 41 and / or the second chamber 42, the gas is heated by the heating baffle 1. The hot gas can heat the part to be heated by heat convection. The multi-mode heating plate can heat the part to be heated by heat conduction, heat radiation and heat convection, which ensures the uniform temperature of the part to be heated after heating, and improves the heating efficiency and heating rate of the multi-mode heating plate for the part to be heated.
[0029] like Figure 3 As shown, the heating partition 1 includes a heating plate 11, a plurality of first heating plate groups 12 and a plurality of second heating plate groups (not shown in the figure); a plurality of the first heating plate groups 12 are installed on the first plate surface of the heating plate 11 along the width direction of the heating plate 11; a plurality of the second heating plate groups are installed on the second plate surface of the heating plate 11 along the width direction of the heating plate 11; it can be understood that the first plate surface and the second plate surface are the opposite surfaces of the heating plate 11 respectively; the first heating plate group 12 is located in the first cavity 41, and the second heating plate group is located in the second cavity 42; the number of the first heating plate group 12 and the second heating plate group can be set according to actual needs.
[0030] The first heating plate group 12 includes a plurality of first bent heating plates 121, and the plurality of first bent heating plates 121 are staggered and overlapped along the width direction of the heating disk; it can be understood that along the width direction of the heating disk, two adjacent first bent heating plates 121 have overlapping parts, and the front first bent heating plate 121 also has an exposed part; the first bent heating plate 121 has a structure similar to that of a tile, and the plurality of first bent heating plates 121 are staggered and overlapped in the form of tiles.
[0031] The second heating sheet group includes a plurality of second bent heating sheets, and the plurality of second bent heating sheets are staggered and stacked along the width direction of the heating disk. It can be understood that along the width direction of the heating disk, two adjacent second bent heating sheets have overlapping parts, and the front two first bent heating sheets 121 also have exposed parts; the second bent heating sheet has a structure similar to that of a tile, and the plurality of second bent heating sheets are staggered and stacked together in the form of tiles.
[0032] In this embodiment, the first bent heating plate 121 and the second bent heating plate are both similar to tile structures. Since heat diffuses outward in the form of thermal radiation (electromagnetic waves), the shape design of the first bent heating plate 121 and the second bent heating plate facilitates the transfer of heat thereon to the heated component in the form of thermal radiation, further improving the heating efficiency of the multi-mode heating plate.
[0033] like Figure 2 As shown, the outer box body 5 is a square box body; the annular partition plate 4 sequentially connects the first partition plate, the third partition plate, the second partition plate and the fourth partition plate, and the end of the first partition plate away from the second partition plate is connected to the end of the fourth partition plate away from the third partition plate; the first partition plate, the second partition plate, the third partition plate and the fourth partition plate are all provided with the pore group 43; the accommodating space is surrounded by the first partition plate, the second partition plate, the third partition plate and the fourth partition plate.
[0034] The first baffle, the second baffle, the third baffle and the fourth baffle are connected to the four sides of the heating baffle 1. In this embodiment, the annular baffle 4 and the outer box 5 have simple structures and low manufacturing costs.
[0035] like Figure 1 As shown, the air inlet connector 2 is provided with an air inlet hole extending along a first preset direction, and the angle between the first preset direction and the length direction of the outer box body 5 is an acute angle; it can be understood that the angle between the first preset direction and the length direction of the outer box body 5 can be set according to actual needs, for example, the angle is equal to 30 degrees, 40 degrees, etc.
[0036] The air outlet connector 3 is provided with an air outlet hole extending along a second preset direction, and the angle between the second preset direction and the length direction of the outer box body 5 is a right angle.
[0037] In this embodiment, the air inlet connector 2 blows gas obliquely into the accommodating space, and the gas can flow in the form of a spiral in the accommodating space. The gas in the annular space 51 can be directly output through the air outlet connector 3; the hot gas flows in the form of a spiral in the accommodating space, thereby forming turbulent gas in the accommodating space, and the turbulent gas further improves the heating efficiency and heating rate of the multi-mode heating plate for the heating element.
[0038] Another embodiment of the utility model further provides a heating device, comprising a heating machine and a plurality of the above-mentioned multi-mode heating trays; the heating machine is provided with a plurality of storage spaces distributed at intervals, and each of the storage spaces can be installed with a multi-mode heating tray.
