[0037] See also Figures 1 to 3 , an embodiment of the present application provides a heat exchange structure 100 and an aerosol generating device having the heat exchange structure 100 .
[0038] Please also see Figure 4 The heat exchange structure 100 includes: an atomizing shell 10 having an atomizing chamber 11 and a heat exchange shell 20 connected to the atomizing shell 10 and capable of being heated by a heat source. It can be understood that the atomizing chamber 11 is used to accommodate the atomizing matrix, and the heat exchange shell 20 is provided with a heat exchange channel connected to the atomizing chamber 11. The heat exchange channel includes a plurality of heat exchange grooves 23, each of which extends along the circumference of the heat exchange shell. The plurality of heat exchange grooves 23 are arranged in sequence along a predetermined direction, and two adjacent heat exchange grooves 23 are connected. The external heat source heats the heat exchange shell 20, so that the air heated by the heat source in the heat exchange shell 20 flows through each heat exchange groove 23 in sequence, and finally flows into the atomizing chamber 11 to heat the atomizing matrix in the atomizing chamber 11.
[0039] Wherein, atomization substrate can be solid atomization substrate.Solid-state substrate can comprise solid component and liquid component.Atomization substrate can comprise tobacco-containing material, and tobacco material contains volatile tobacco flavor compounds released from substrate when heated.Atomization substrate can comprise non-tobacco material.In addition, atomization substrate can also comprise one or more aerosol forming agents adsorbed in tobacco material, and when volatilizing, aerosol forming agent can transmit other volatile compounds such as nicotine and flavoring agents released from aerosol generation substrate when heated in aerosol.
[0040] The heat source may be an electric heating element, such as a resistance heating element, electromagnetic heating, laser heating, infrared heating, etc., which converts electrical energy into thermal energy to heat the heat exchange shell 20; the heat source may also be a flame heating element, which generates a high-temperature burning flame by burning a flammable liquid, solid or gas, and then heats the heat exchange shell 20 by the burning flame; the heat source may also be a chemical heating element, which generates an exothermic reaction by pre-set chemicals to heat the heat exchange shell 20. In the embodiment of the present application, the heat source is a flame heating element, which directly heats the heat exchange shell 20, thereby heating the gas in the heat exchange tank 23. Other embodiments may be selected according to actual conditions, and are not limited here.
[0041] It can be understood that the air flows inward from the outermost heat exchange groove 23 and flows through each heat exchange groove 23 in turn, which extends the heating path of the air, enables the air to obtain sufficient heat from the heat source, and improves the heating efficiency, so that the air entering the atomization chamber 11 reaches a predetermined temperature, which is the heating temperature of the atomization matrix, thereby improving the taste of subsequent inhalation. The air is heated by the heat exchange shell 20 and then flows into the atomization chamber 11, which can avoid the heat source from directly heating the atomization matrix in the atomization chamber 11, prevent the temperature of the atomization matrix in the atomization chamber 11 from being too high, thereby avoiding the atomization matrix from generating burnt smell or other odors.
[0042] See also Figure 1 and Figure 2 In one embodiment of the present application, the shape of the extension path of the heat exchange groove 23 can be circular, elliptical or polygonal, so that the shape of the heat exchange groove 23 can also be arranged in a circular, elliptical or polygonal shape accordingly. In this embodiment, the shape of the heat exchange groove 23 is arranged in a circular ring, and multiple heat exchange grooves 23 are arranged in an array along the center of the ring pointing to the outside of the ring, and any two adjacent heat exchange grooves 23 are connected. The heat source is used to heat the heat exchange shell 20, so that the air in the heat exchange shell 20 is heated and flows through each heat exchange groove 23 in sequence and flows into the atomization chamber 11.
[0043] Optionally, in other embodiments, the shape of the extension path of the heat exchange groove 23 may be an ellipse or a polygon, which is selected according to actual conditions and is not limited here.
[0044] Please continue reading Figure 2 In some embodiments, the heat exchange shell 20 is provided with a accommodating cavity 27, and the heat exchange structure 100 further includes a partition plate 21 located in the accommodating cavity 27, the partition plate extends along the circumference of the heat exchange shell 20, the partition plates 21 are connected to the cavity bottom of the accommodating cavity 27 and multiple partition plates 21 are arranged at intervals, any two adjacent partition plates 21 and the cavity bottom of the accommodating cavity 27 jointly define a heat exchange groove 23, and a connecting notch 24 connecting two adjacent heat exchange grooves 23 is provided on the partition plate 21.
[0045] It can be understood that two connecting gaps 24 are arranged at intervals on each heat exchange groove 23, and one of the connecting gaps 24 is for air to flow into the heat exchange groove 23. After the air is heated in the heat exchange groove 23 and is fully and evenly heated, it flows into the next heat exchange groove 23 from the other connecting gap 24, and finally the air flowing into the atomization chamber 11 reaches a predetermined temperature and improves the heating efficiency.
[0046] In some embodiments, the bottom of the accommodating cavity 27 is arranged in a plane, and the predetermined direction is parallel to the bottom of the accommodating cavity 27. Each heat exchange groove 23 is arranged in the same plane to form a maze structure. Forming multiple heat exchange grooves 23 into a maze structure can extend the air flow path and improve the heating efficiency.
[0047] See also Figure 2 and Figure 5 In some embodiments, each communication notch 24 is arranged in a circle and staggered around the center position of the bottom of the accommodating chamber 27. It can be understood that the positions of each communication notch 24 and the center position of the bottom of the accommodating chamber 27 are arranged linearly, and the two communication notches 24 located on the same heat exchange groove 23 are located on both sides of the center position, so that the air flowing into the heat exchange groove 23 from one of the communication notches 24 can flow in two directions, along both sides of the heat exchange groove 23, and then flow out of the heat exchange groove 23 from the other communication notch 24, thereby extending the air flow path and improving the heating efficiency.
[0048] See also Figure 3 In some other embodiments, the number of heat exchange grooves 23 can be one, and the extension path of the heat exchange grooves 23 is arranged in a spiral line. The atomization chamber 11 is connected to the heat exchange grooves 23 at the center of the spiral line. The air flows into the heat exchange grooves 23 from the outermost layer and flows toward the center along the spiral line, so that the air flowing into the atomization chamber 11 is fully heated, thereby improving the heating efficiency.
[0049] See also Figures 1 to 4Optionally, the heat exchange housing 20 is cylindrical, and the heat source is used to heat the bottom of the accommodating chamber 27, and the heat source is located at the center of the bottom of the accommodating chamber 27, so that the air near the center is heated quickly and has a high temperature, and the air in the area away from the center of the bottom of the accommodating chamber 27 is preheated and flows toward the center of the ring, and finally is heated to a predetermined temperature and flows into the atomizing chamber 11. Please refer to Figure 6 , Figure 8 , Fig. 9 , Fig.12 and Fig.14 In some embodiments, the bottom of the accommodating cavity 27 faces the atomizing shell and bulges inward to form a raised portion 201. The predetermined direction is along the raised direction of the raised portion 201. The partition plates 21 are arranged in sequence along the raised direction and are all jacketed on the raised portion 201. A heat exchange groove 23 is jointly defined between any two adjacent partition plates 21 and the side surfaces of the raised portion 201. When the heat exchange structure 100 is placed vertically, air flows through the heat exchange grooves 23 from bottom to top in sequence and flows into the atomizing cavity 11 after being heated.
[0050] See also Figure 6 , 8 12. In some embodiments, the raised portion 201 is a hollow structure and has a heating chamber 26 for accommodating a heat source. By arranging the heat source in the heating chamber 26, the flame burns in the heating chamber 26, thereby increasing the heating area of the heat exchange housing 20 and effectively improving the heating efficiency. After the gas is ignited, the flame heats the inner wall of the entire heating chamber 26, and the air in the heating chamber 26 heats up rapidly. When the atomized substrate in the atomizing chamber 11 is inhaled, the high-temperature air in the heat exchange groove 23 is inhaled into the atomizing chamber 11, so that the atomized substrate generates an aerosol for inhalation.
[0051] It can also be understood that the surface of the heat exchange housing 20 facing away from the bottom of the accommodating cavity 27 is recessed toward the accommodating cavity 27 to form a heating cavity 26 for accommodating the heat source.
[0052] See also Figure 5 and Figure 8 In some embodiments, each heat exchange groove 23 is arranged around the same central axis, that is, the central axis passes through the bottom of the accommodating cavity 27. When the bottom of the accommodating cavity 27 is arranged in a plane, the central axis is perpendicular to the bottom of the accommodating cavity 27, and the predetermined direction is perpendicular to the axial direction of the central axis. When the bottom of the accommodating cavity 27 bulges inward, the axial direction of the central axis is arranged along the bulging direction.
[0053] See also Figure 2 In some embodiments, the groove width of the heat exchange groove 23 is arranged with equal width from one connecting notch along the circumference of the heat exchange shell to the other connecting notch, that is, the groove width at each position of the heat exchange groove 23 is equal, so that the air can flow in the heat exchange groove 23 and fully absorb heat.
[0054] In some embodiments, the groove width of the heat exchange groove 23 is gradually reduced from one of the connecting gaps 24 along the circumference of the heat exchange shell to the other connecting gap, that is, the groove width of the heat exchange groove 23 is different at at least two positions. For example, the groove width of the heat exchange groove 23 is widest at one of the connecting gaps 24 and narrowest at the other connecting gap. The groove width of the heat exchange groove 23 gradually narrows, which increases the air flow speed and causes turbulence, so that the air in the heat exchange groove 23 is fully heated and the temperature uniformity is improved.
[0055] See also Fig.10 Optionally, only one heat exchange groove 23 may be provided, that is, each partition plate 21 is disconnected and connected end to end in sequence, and the whole is arranged in a spiral, and the extension path of the heat exchange groove 23 is arranged in a spiral line around the circumference of the raised portion 201, and the air flows into the heat exchange groove 23 from the lower end of the spiral line, and flows into the atomization chamber 11 from the upper end of the spiral line.
[0056] See also Fig.11 In some embodiments, the heat exchange shell 20 is provided with an exhaust hole 282, and the exhaust hole 282 is connected to the heating chamber 26 and the external space.
[0057] Optionally, the exhaust hole 282 is arranged close to the atomization chamber 11, and the high-temperature exhaust gas after combustion can be discharged from the exhaust hole 282 at the top of the heat exchange chamber. As the hot air flow reduces the pressure in the heating chamber 26, fresh air can continue to flow in from the bottom of the heating chamber 26 to provide the oxygen required for gas combustion and keep the flame in a burning state.
[0058] Please continue reading Fig.11 Optionally, the heat exchange structure 100 also includes an air guide sleeve 281, the two ends of which are respectively connected to the heat exchange shell 20 and the atomization shell 10, and the inner cavity of the air guide sleeve 281 is connected to the heating chamber 26, and the exhaust hole 282 is opened on the side wall of the air guide sleeve 281, so that the exhaust gas in the heating chamber 26 can be discharged to the external space through the air guide sleeve 281, and the exhaust gas is prevented from entering the atomization chamber 11.
[0059] See also Figure 8 and Fig.13 In some embodiments, the heat exchange structure 100 is further provided with an air inlet channel 30, and the two ends of the air inlet channel 30 are respectively connected to the atomization chamber 11 and the heat exchange groove 23. It can be understood that the air inlet channel 30 is connected to the innermost heat exchange groove 23, or the air inlet channel 30 is connected to one end of the spiral heat exchange groove 23, so that the heated air in the heat exchange groove 23 can flow into the atomization chamber 11 through the air inlet channel 30.
[0060] See also Fig.13 and Fig.14 In some embodiments, the heat exchange shell 20 is further provided with an air inlet 22 , and the air inlet 22 is connected to one of the heat exchange slots 23 .

[0063] Optionally, the heat-conducting column 29 is located on the surface of the heat-exchange housing 20 facing away from the bottom of the accommodating cavity 27. By providing a plurality of heat-conducting columns 29, the heating area of the heat-exchange housing 20 can be increased, and the heat energy generated by the flame combustion can be fully absorbed to transfer the heat to the heat exchange groove 23. When the flame heats the bottom of the accommodating cavity 27, the heat-conducting column 29 at the bottom is also heated, which increases the heating area of the bottom, improves the energy conversion efficiency, and improves the heating efficiency.
[0064] Optionally, the material of the heat-conducting column 29 can be a metal material with good thermal conductivity, such as copper, which is not limited here and can be selected according to actual conditions.
