[0019] With the continuous development of e-cigarette technology, the design of its internal structure and components has become increasingly sophisticated to meet users' high demands for performance, safety, and portability. The heating element inside an e-cigarette generates a significant amount of heat. If this heat cannot be dissipated in time, it can lead to overheating, affecting the user experience and potentially causing safety issues. The heat sink, as a crucial component of e-cigarettes, plays a vital role in ensuring that the heat generated during use is effectively managed, preventing overheating and thus guaranteeing both user experience and safety.
[0020] Traditional sleeve heat sinks are generally U-shaped and are placed over the heating element. However, U-shaped sleeve heat sinks have insufficient heat dissipation capacity, which can easily cause the local temperature of the e-cigarette to become too high, leading to the release of harmful substances due to the high temperature of the e-cigarette and affecting the user experience.
[0021] To solve the above problems, please refer to... Figures 1 to 4 This utility model proposes a heat sink structure 10, including a first heat sink 1 and a second heat sink 2, which are connected and arranged side by side. The first heat sink 1 encloses a first mounting cavity 1a with an opening, and the second heat sink 2 encloses a second mounting cavity 2a with an opening. The inner peripheral wall of the first heat sink 1 has a first heat dissipation surface, and the inner peripheral wall of the second heat sink 2 has a second heat dissipation surface. The first heat dissipation surface is used to contact the components disposed in the first mounting cavity 1a, and the second heat dissipation surface is used to contact the components disposed in the second mounting cavity 2a.
[0022] The technical solution of this utility model adopts a first heat sink 1 and a second heat sink 2 arranged side by side. These two independent heat sinks dissipate heat from different components, thereby achieving more efficient thermal management. Specifically, the side-by-side arrangement of the first heat sink 1 and the second heat sink 2 allows the heat sink structure 10 to simultaneously dissipate heat from multiple components within a limited space, improving heat dissipation efficiency. The mounting cavity formed by each heat sink can accommodate different components, such as the heating element 40, the motherboard 20, and the battery 30, while the heat dissipation surface directly contacts the components, ensuring rapid heat transfer to the heat sink. This design not only improves heat dissipation efficiency but also effectively reduces the temperature of the components, extending their service life. Furthermore, by designing the heat sinks to be arranged side by side, the overall volume of the heat sink can be reduced, making it more suitable for space-constrained applications, such as small electronic devices like electronic cigarettes 100. This heat sink structure 10 design offers high practicality and flexibility in practical applications, meeting the heat dissipation needs of different components while ensuring stable operation of the device.
[0023] In an alternative embodiment, please refer to Figure 1 and Figure 2The first heat sink 1 has openings connecting to the first mounting cavity 1a at both ends near and away from the second heat sink 2, and the second heat sink 2 has openings connecting to the second mounting cavity 2a at both ends near and away from the first heat sink 1. In actual design, the first heat sink 1 and the second heat sink 2 can be either a semi-enclosed, open structure or a circumferentially closed tubular structure. In this embodiment, the first heat sink 1 and the second heat sink 2 are respectively enclosed to form a circumferentially closed, tubular structure, forming a first sleeve and a second sleeve. This sleeve structure enables enveloping heat dissipation of the components, thereby improving the heat dissipation effect. The sleeve structure design allows the heat sink to fit tightly against the components, ensuring that heat can be quickly transferred to the heat sink. In addition, the closed sleeve structure is stronger than the open structure, making the heat sink structure 10 more stable and less prone to deformation. This provides a certain degree of mechanical protection, preventing the components located in the mounting cavity from being affected by external impacts or vibrations. Specifically, the first and second sleeves are used to house different components. In this embodiment, the heating element 40 is housed in the first sleeve, while the motherboard 20 and battery 30 are housed in the second sleeve. The sleeve's enveloping design ensures that the heat dissipation surface can fully contact the surface of the components, guaranteeing rapid heat transfer to the heat sink. This design not only improves heat dissipation efficiency but also effectively reduces the temperature of the components, extending their lifespan. Furthermore, the sleeve structure design reduces the overall volume of the heat sink, making it more suitable for space-constrained applications, such as small electronic devices like the electronic cigarette 100. This heat sink structure 10 design offers high practicality and flexibility in real-world applications, meeting the heat dissipation needs of different components while ensuring stable device operation.
[0024] In an optional embodiment, the first heat sink 1 and the second heat sink 2 are an integral structure. This integral structure improves the overall strength and stability of the radiator structure 10. The integrated design allows the first heat sink 1 and the second heat sink 2 to be manufactured as a single unit, thus preventing a decrease in heat dissipation due to loosening or detachment of the connecting parts 31. Specifically, the integral structure makes the radiator more stable during use, effectively resisting the effects of external impacts and vibrations. Furthermore, the integral structure reduces manufacturing costs and assembly time, improving production efficiency. In practical applications, the integral structure radiator can better adapt to various complex operating environments, ensuring stable equipment operation. This design not only improves the reliability and durability of the radiator but also effectively reduces production costs, offering high economic efficiency and practicality. Moreover, the integral structure simplifies the forming steps of the radiator structure 10. In this embodiment, the radiator structure 10 is made of aluminum alloy sheet, and the integral stamping and bending of the aluminum sheet simplifies the production process and reduces production costs.
[0025] In an alternative embodiment, please refer to Figure 1 and Figure 2 To further improve the heat dissipation effect of the second heat sink 2, a protruding structure 21 is formed on the peripheral wall of the second heat sink 2, which protrudes away from the second mounting cavity 2a and / or faces the second mounting cavity 2a. The protruding structure 21 helps to increase the surface area of the heat dissipation surface of the second heat sink 2, thereby improving the heat dissipation effect. The design of the protruding structure 21 allows the heat dissipation surface to form a better fit with the components in the second mounting cavity 2a, so that the components can conduct heat to the heat sink structure 10 through contact and dissipate it, achieving a better heat dissipation effect. In actual design, since the internal components of different types of electronic cigarettes 100 have different structural shapes, the protruding structure 21 on the second heat sink 2 can be a protruding structure 21 facing outward from the second mounting cavity 2a or a protruding structure 21 facing inward from the second mounting cavity 2a, which can be arranged according to the actual structure. Moreover, the protruding structure 21 can be formed in one stamping, reducing the process steps required for production. The design of the protruding structure 21 can effectively reduce the temperature of the components and extend their service life. This design not only improves the heat dissipation performance of the radiator, but also adapts to different heat dissipation needs, making it highly practical and flexible.
[0026] In an alternative embodiment, please refer to Figure 1 and Figure 2 To further facilitate the installation of internal components of the electronic cigarette 100, the first heat sink 1 includes a mounting portion 11 and a bending portion 12. The mounting portion 11 and the bending portion 12 are integrally arranged along the width direction of the heat sink structure 10. The bending portion 12 is bent inward to form a tubular structure, and the mounting portion 11 has a mounting surface. The main function of this design is to realize the installation and fixation of components through the structural design of the mounting portion 11 and the bending portion 12. The mounting portion 11 has a mounting surface, which can be used to install the sub-board 50 or other components, while the bending portion 12 forms a first sleeve for accommodating the heating tube 40. Its inner peripheral wall is in contact with the heating tube 40 to achieve rapid heat conduction, thereby improving the corresponding heat dissipation effect. Furthermore, the heating tube 40 and the sub-board 50 are separated by a certain distance through the first sleeve, which can also prevent the heat from the heating tube 40 from affecting the normal operation of the sub-board 50 and ensure the safety of the electronic cigarette 100. Furthermore, the mounting part 11 is formed with a clearance groove 111. The clearance groove 111 can also be adapted to the design of the components mounted on the mounting surface so that the mounting part 11 and the corresponding components can fit together better, thereby ensuring good heat dissipation.
[0027] Optionally, the end of the mounting portion 11 away from the bending portion 12 is bent along the side facing the first mounting cavity 1a to form a retaining edge. The retaining edge prevents components such as the sub-plate 50 mounted on the mounting portion 11 from easily slipping out, ensuring stable mounting of the components and preventing them from loosening or falling off due to vibration or other external forces during use. The retaining edge also increases the contact area between the mounting portion 11 and the components, improving the fixing effect. Furthermore, the inner wall of the retaining edge can also contact the components, improving the efficiency of heat conduction and thus enhancing the heat dissipation effect on the components. In practical applications, the retaining edge design effectively improves the reliability and stability of the heat sink structure 10, allowing it to adapt to different operating environments and improving the practicality and flexibility of the heat sink structure 10.
[0028] In an optional embodiment, to facilitate the forming of the radiator structure 10, the first heat sink 1 and the second heat sink 2 have a first bent edge and a second bent edge at their circumferential ends, respectively, and the first bent edge and the second bent edge are riveted together. This riveting method allows the first heat sink 1 and the second heat sink 2 to connect as a whole after bending, ensuring the strength of the radiator structure 10 while improving its heat dissipation effect. This ensures greater stability of the radiator during use and effectively resists the effects of external impacts and vibrations. Furthermore, the riveting method reduces the manufacturing cost and assembly time of the radiator, improving production efficiency. In practical applications, the riveting design better adapts to various complex operating environments, ensuring the stable operation of the radiator structure 10; it not only improves the reliability and durability of the radiator but also effectively reduces production costs, exhibiting high economic efficiency and practicality.
[0029] Optional, please refer to Figure 2 and Figure 3Both the first heat sink 1 and the second heat sink 2 are equipped with connecting components 3. The connecting components 3 include connecting portions 31 and connecting holes 32 arranged on both sides along the width direction of the heat sink structure 10. The connecting portions 31 have a tubular structure, and the connecting holes 32 have a straight section and a tapered section along the axial direction. The first heat sink 1 and the second heat sink 2 are bent so that the connecting portions 31 are inserted into the connecting holes 32 and circumferentially outwards to hook with the tapered sections. The connecting components 3 enable rapid assembly and fixation of the heat sink structure 10. The design of the connecting components 3 makes the assembly of the heat sink structure 10 more convenient and faster, reducing assembly time. Specifically, the connecting component 3 is fixed by cold riveting. The connecting part 31 is a tubular structure integrally set on one side of the first heat sink 1 / second heat sink 2. A connecting hole 32 is opened on the other side corresponding to the connecting part 31. During forming, the aluminum plate after stamping is bent to form the first sleeve and the second sleeve, so that the connecting part 31 is inserted into the connecting hole 32. A tool is inserted into the middle hole of the connecting part 31 to make it turn outward along the circumference to press the tapered section of the connecting hole 32, thereby achieving the effect of hooking the connecting part 31 and the connecting hole 32, realizing the bending and fixing of the first heat sink 1 and the second heat sink 2. This not only ensures the strength of the connection, but also simplifies the processing process.
[0030] This utility model also proposes an electronic cigarette 100, which includes a heat sink structure 10, a motherboard 20, a battery 30, and a heating element 40. The specific structure of the heat sink structure 10 is as described in the above embodiments. Since this electronic cigarette 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. Please refer to... Figure 1 , 3 4. The heating element 40 is located in the first mounting cavity 1a and abuts against the inner wall of the first heat sink 1. The main board 20 and battery 30 are located in the second mounting cavity 2a and abut against the inner wall of the second heat sink 2. Specifically, by setting a bracket in the heat sink structure 10, the main board 20 and battery 30 are mounted on both sides of the bracket, so that the main board 20 and the bracket can abut against the two inner side walls of the second connector, thereby achieving a powerful heat dissipation effect. In addition, a sub-board 50 or other components can be set at the mounting part 11, which can be selected according to actual needs. The heat sink structure 10 in this solution can effectively dissipate heat from components such as the heating element 40, main board 20, sub-board 50 and battery 30, preventing equipment failure or safety hazards caused by overheating. In addition, the reasonable design and utilization of the internal space of the heat sink structure 10 can also reduce the overall size of the electronic cigarette 100, making it more suitable for portable use. In practical applications, this design can effectively improve the safety and reliability of the electronic cigarette 100 and extend its service life. It not only improves the heat dissipation performance of the electronic cigarette 100, but also adapts to different usage environments, making it highly practical and flexible.
