[0058] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0059] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0060] The present invention will be described in detail below in conjunction with exemplary embodiments with reference to the accompanying drawings.

[0061] Example 1

[0062] refer to Figures 1 to 6 The heating smoking device 60 mainly includes a heating element 20, a vacuum insulation tube 30, a bracket 40, a battery core and a shell 50. A design method for a heating smoking device based on gridless simulation of the present invention comprises the following steps:

[0063] Step A: obtaining a simulation model of the heating smoking device 60;

[0064] Specifically, the simulation model of the heating smoking device 60 can be pre-established; it can also be directly obtained through a local database or from a server stored in the cloud; or, according to the actual structure and working principle of the heating smoking device, appropriate simulation software, such as COMSOL, ANSYS, FLUENT and other software, can be selected to establish the simulation model of the heating smoking device by using the simulation software.

[0065] It can be understood that the specific process of establishing the simulation model is well known to those skilled in the art and will not be described in detail here.

[0066] The simulation model file is in an interactive format, such as .stp or .x_t, etc. By importing the circumferential heating smoking device model file in the interactive format of .stp or .x_t into the meshless simulation software, the heat transfer performance of the heating smoking device can be analyzed.

[0067] It can be understood that the present invention forms a gridless simulation method suitable for circumferential heating devices by establishing a standardized simulation process suitable for circumferential heating devices. The gridless simulation method can import the core component model of the device according to the heat transfer performance of the core component of the device, input the material properties and boundary conditions of the component, perform real-time simulation, and obtain the temperature cloud map and temperature value of the core component. The above steps can realize the real-time rapid simulation of the overall heating device, and obtain the visual simulation results such as the overall temperature field and local temperature value of the circumferential heating device.

[0068] Step B: analyzing the heat transfer performance of the heating smoking device according to the simulation model obtained in step A, and determining the heating core component of the heating smoking device;

[0069] Specifically, the step B specifically includes:

[0070] Simulate the heating device to be in working state, and analyze whether the temperature change of each core component of the heating device is greater than a preset threshold:

[0071] If yes, it is determined that the core component is the heat generating core component;

[0072] If not, it is determined that the core component is a non-heat-generating core component.

[0073] Step C: Based on the simulation model, using the physical parameters of the heating smoking device, performing temperature simulation calculation on the temperature data of the heating core component;

[0074] Exemplarily, the main components of the heating smoking device 60 (for example: the heating element 20, the vacuum insulation tube 30, the bracket 40, the battery cell, the shell 50, etc.) are analyzed. Considering that the influence of the battery cell on the overall heat transfer performance of the circumferential heating device is extremely weak, the heating element 20 of the device is heated to 250°C, the temperature of the shell 50 is usually 40-55°C, and the temperature of the battery cell is usually kept in the low temperature range (20-30°C). Therefore, the heat transfer simulation of the battery cell components can be ignored, and it is determined that the heating element 20 is the heating core component one, the vacuum insulation tube 30 is the heating core component two, the bracket 40 is the heating core component three, and the shell 50 is the heating core component four.

[0075] It should be noted that the meshless simulation software used in the embodiment of the present invention is ANSYS Discovery. ANSYS Discovery uses adaptive modeling technology and does not require pre-optimization of the mesh or definition of boundary conditions. After the engineer enters the simulation model and boundary conditions, the next two steps (creating or updating the mesh, selecting or starting the solver) can be automatically triggered. Compared with traditional finite element analysis, engineers no longer need to perform tedious mesh processing and solver selection. Adaptive modeling technology can automatically generate meshes for geometric shapes. Regardless of the size or complexity of the geometric shapes, the corresponding simulation results can be obtained through this technology. The minimum requirements for the simulation environment are as follows: 64-bit Intel or AMD system, running Windows 10, 8GB of memory, a dedicated graphics card with the latest driver and at least 1GB of video memory, and can support OpenGL 4.5 and DirectX 11 or higher.

[0076] It can be understood that due to the particularity of the structure of heated tobacco products, heat transfer simulation calculations can be performed with the help of a gridless fast simulation method, and the original two steps in the traditional simulation process (creating or modifying the geometric model, defining the structural load and boundary conditions) can be merged into one step, that is, simplifying or modifying the model while defining the model's operating environment; then the operation of meshing the model in the traditional simulation process is omitted. The quality of the meshing directly affects the reliability of the simulation results, and professional simulation engineers are required to analyze the model and set the corresponding mesh type and mesh unit size. The gridless simulation technology does not require manual operation, and the background automatically performs meshing according to the model. You only need to select the fidelity size (that is, the accuracy of the meshing); then you can click the solve button to perform calculations, which simplifies a series of highly professional manual operations in the traditional simulation process, such as selecting a heat transfer solution model, setting solver parameters, setting flow field initialization, and setting the number of iterations; the temperature cloud map of the model is presented in less than 1 minute.

[0077] Specifically, if the heating core component is a heating element 20, the step C includes:

[0078] Step C1: Determine the inner diameter, thickness and material of the heating element;

[0079] Step C2: Based on the inner diameter, thickness and material of the heating element, a temperature simulation calculation is performed on the heating element to obtain a temperature cloud map of the heating element.

[0080] For example, the design structure and heat transfer characteristics of the heating core component 1 (heating element 20) can be combined to perform gridless simulation. According to the imported heating core component 1 model, the heating element 20 is a cylinder with an inner diameter of 3mm and a thickness of 0.2mm, and a vacuum insulation tube 30 is spaced a certain distance outside; as a small electric heating device, the gap between the heating element 20 and the vacuum insulation tube 30 has a greater impact on the overall heat transfer performance. Combined with the study of narrow spaces, the gap between the heating element 20 and the vacuum insulation tube 30 is greater than 1mm. The simulation is based on fluid heat transfer, and the heat transfer coefficient is 12W / (m 2 ·℃); Material properties: The heating element 20 is made of stainless steel 304, and the vacuum insulation tube 30 is made of aluminum; Boundary conditions: The heating element 20 is set to solid heat transfer, the temperature is 250℃, the environment is set to air fluid, convection heat transfer, the temperature is 25℃, and the heat transfer coefficient is 12W / (m 2 ℃). Then select a suitable fidelity and press the solve button. Wait for less than 30 seconds to obtain the temperature cloud map of the heating element 20, such as Figure 2 shown.

[0081] Specifically, if the heating core component is a vacuum insulation tube 30, the step C includes:

[0082] Step C3: determining the vacuum degree, thickness and material of the vacuum insulation tube;

[0083] Step C4: Based on the vacuum degree, thickness and material of the vacuum insulation tube, temperature simulation calculation is performed on the vacuum insulation tube to obtain a temperature cloud map of the vacuum insulation tube.

[0084] For example, the gridless simulation is applied to the core heating component 2 (vacuum insulation tube 30) in combination with its design structure and heat transfer characteristics. According to the imported core heating component 2 model, the vacuum insulation tube 30 is a certain distance away from the heating element 20. The vacuum insulation tube 30 is a double-layer stainless steel cylinder with an internal vacuum degree of 0.5Pa and a thickness of 0.05mm. As a small electric heating device, the gap between the heating element 20 and the vacuum insulation tube 30 has a great influence on the overall heat transfer performance. Combined with the study of narrow spaces, the gap between the heating element 20 and the vacuum insulation tube 30 is greater than 1mm. The simulation is based on fluid heat transfer, and the heat transfer coefficient is 12W / (m2 ·℃); Material properties: The heating element 20 is made of aluminum, and the vacuum insulation tube 30 is made of stainless steel 304; Boundary conditions: The heating element 20 is set to solid heat transfer, the temperature is 250℃, the environment is set to air fluid, convection heat transfer, the temperature is 25℃, and the heat transfer coefficient is 12W / (m 2 ℃). Then select a moderate fidelity and press the solve button. Wait for less than 30 seconds to obtain the temperature cloud map of the vacuum insulation pipe 30, such as Figure 3 shown.

[0085] Specifically, if the heating core component is the bracket 40, the step C includes:

[0086] Step C5: determining the thermal conductivity and material of the bracket;

[0087] Step C6: Based on the thermal conductivity and material of the bracket, a temperature simulation calculation is performed on the vacuum insulation pipe to obtain a temperature cloud map of the vacuum insulation pipe.

[0088] Exemplarily, a gridless simulation application is performed on the third core heating component (bracket 40) in combination with its design structure and heat transfer characteristics. According to the imported core heating component 3 model, the bracket 40 mainly supports the battery core and the heating component (the heating component includes the heating element 20, the vacuum insulation tube 30, the heating element shell 50, and the insulation material layer), and blocks the heat transfer of the heating component as much as possible. Therefore, the bracket 40 adopts polyetheretherketone (PEEK) material with low thermal conductivity and high heat resistance; considering the influence of the contact area during the heat conduction process of the bracket 40, the heat transfer contact is reduced as much as possible. Therefore, the contact between the bracket 40 and the heating component, and the bracket 40 and the connector are designed to be point contacts. Combined with the simplified calculation of the contact thermal resistance, the contact thermal resistance value can be calculated. In the simulation operation, the thermal conductivity of the point contact between the corresponding component and the bracket 40 is specified (the thermal conductivity is is the reciprocal of thermal resistance); at the same time, as a small electric heating product, the existence of internal gaps has a great influence on the overall heat transfer performance. Combined with the study of narrow space, the gap between the bracket 40 and the heating element 20 is less than 0.1mm. At this time, the nature of non-fluid heat transfer can be simplified to contact thermal resistance. In the simulation operation, the thermal conductivity of the contact between the bracket 40 and the heating component shell 50 is specified (thermal conductivity is the reciprocal of thermal resistance); material properties: PEEK material is selected for the bracket 40, and stainless steel 304 material is selected for the heating component; boundary conditions: the heating component is set to solid heat transfer, temperature 100℃, the environment is set to air fluid, convection heat transfer, temperature 25℃, and the thermal conductivity of the contact between the heating component and the bracket 40 is set to 2e3 W / (m 2 ·℃), the thermal conductivity of the contact point is set to 2e3 W / (m 2 ℃). Then select a moderate fidelity and press the solve button. Wait for less than 30 seconds to obtain the temperature cloud map of the bracket 40, such as Figure 4 shown.

[0089] Specifically, if the heat generating core component is the housing 50, the step C includes:

[0090] Step C7: Determine the material, thermal conductivity and specific heat capacity of the shell;

[0091] Step C8: Based on the material, thermal conductivity and specific heat capacity of the shell, a temperature simulation calculation is performed on the shell to obtain a temperature cloud map of the shell.

[0092] For example, the design structure and heat transfer characteristics of the core heating component 4 (housing 50) are combined to perform gridless simulation. According to the imported core heating component 4 model, the housing 50 is the main component that contacts the human body, and uniform heat and suitable temperature are important design objectives of the housing 50. Therefore, polyetheretherketone (PEEK) material with low thermal conductivity and high heat resistance is used; there is a certain gap between the housing 50 and the internal components. The existence of the internal gap of the small electric heating device has a great influence on the overall heat transfer performance. Combined with the study of the narrow space, the gap between the housing 50 and the internal components is in the range of 0.1-1mm, and the convective heat transfer is extremely low, which can be simplified into solid heat transfer. Therefore, in the simulation operation, the heat transfer between the shell 50 and the internal components is simplified to solid heat transfer, with a thermal conductivity of 2W / (m·K) and a specific heat of 1.8kj / (kg·℃); the natural cooling process between the shell 50 and the external environment is a complex heat transfer process, in which the comprehensive heat transfer coefficient is an important parameter for the natural cooling of the shell 50, which is mainly affected by natural convection and radiation heat transfer. Since the actual shell 50 temperature of the circumferential heating device is not high and the use environment is mild, the range of the comprehensive heat transfer coefficient is narrow, and the accuracy of the simplified comprehensive heat transfer calculation fully meets the requirements of the heat transfer simulation design. According to the simplified equation of the comprehensive heat transfer coefficient, the ambient temperature T0 is taken between 20 and 25℃, and the wall temperature T w Between 30 and 40°C, the comprehensive heat transfer coefficient α is calculated T 9~11W / (m 2 ·℃). Therefore, in the simulation operation, the heat transfer of the housing 50 is simplified to a comprehensive heat transfer coefficient of 10W / (m 2 ·℃); Material properties: PEEK material is selected for the shell 50, and PEEK material is selected for the internal parts; Boundary conditions: The internal parts are set to solid heat transfer, the temperature is 85℃, the heat transfer between the shell 50 and the internal parts is set to solid heat transfer, the thermal conductivity is 2W / (m·K), the specific heat is 1.8kj / (kg·℃), the environment is set to air, convection heat transfer, the temperature is 25℃, and the thermal conductivity of the shell 50 is 10W / (m 2 ℃). Then select a suitable fidelity and press the solve button. Wait for less than 30 seconds to obtain the temperature cloud map of the shell 50, such as Figure 5 shown.

[0093] Step D: The temperature data of the core component is simulated and presented through a visualization system.

[0094] By performing gridless simulation on the heating device 60 (circumferential heating device) through the above steps, the overall heat transfer result of the device can be quickly obtained, that is, the overall temperature cloud diagram of the heating device 60, such as Figure 6 The local temperature value of the device can also be obtained, among which the maximum temperature of the device wall is 50.7℃.

[0095] It is understandable that the meshless fast simulation method can flexibly adapt to any changes in the simulation input, such as processing the geometry or reselecting materials or further modifying the simulation boundary condition input. Click Solve and the simulation results will be automatically updated. In this case, we choose to further adjust the fidelity (i.e. the accuracy of the calculation results) and wait for about 30 seconds. The adjusted simulation results are immediately displayed on the screen in the form of a temperature cloud map. The entire process of meshless simulation runs completely automatically without much operation.
