Description
Technical Field
[0001] The present application relates to the technical field of electronic product testing, and in particular to an electronic product charging environment simulation box. Background Art
[0002] With the continuous development of science and technology, the performance of electronic products has been improved and the charging power has increased. The heating problem of electronic products during the charging process has become increasingly prominent. In order to ensure the quality and safety of electronic products during the design and manufacturing process, it is necessary to test the performance of electronic products during the charging process. In these tests, it is necessary to simulate an environment with constant temperature and relatively no wind for testing.
[0003] At present, although the existing simulation box equipment can provide a certain temperature control function, it often has problems such as large temperature fluctuations and inability to maintain a windless state, resulting in inaccurate test results. Specifically, the simulation box equipment on the market mainly adopts the method of placing heating tubes inside the box for heating. The temperature inside the box is monitored by installing a temperature sensor inside the box, and air convection is generated inside the box through a fan so that each position inside the box has a relatively uniform temperature. However, this heating method is easily affected by the heat generated by the operation of the equipment to be tested, resulting in the temperature in the box continuing to rise and unable to maintain the required temperature. It will also form turbulence inside the box, destroying the original need to simulate a relatively windless environment, resulting in deviations in the measurement results. This situation needs to be improved. Summary of the invention

This is especially important for equipment that requires frequent entry and exit or regular maintenance. If adjustments are required during the test, if the entire operating door is opened, it is easy to affect the temperature inside the box and damage the simulated environment inside the box. Therefore, an operating port is opened on the operating door. The user can fine-tune the test product from the operating port by opening the sealing plate.

[0032] The embodiment of the present application discloses an electronic product charging environment simulation box.
[0033] Reference Figure 1 and Figure 2, an electronic product charging environment simulation box includes a box body 1, a test table 2, a heating mechanism 3, a temperature detection mechanism 4 and an airflow control mechanism 5; the test table 2, the heating mechanism 3, the temperature detection mechanism 4 and the airflow control mechanism 5 are all installed in the inner cavity of the box body 1. The test table 2 is a platform for placing the electronic product or device to be tested, which is usually located at the headquarters position of the inner cavity of the box body 1 to ensure that the device to be tested can be fully affected and tested by the simulated environment. The heating mechanism 3 is used to generate heat to ensure that the temperature conditions of the electronic product to be tested during the charging process meet the expected or specific test requirements. The temperature detection mechanism 4 is used to monitor and record the temperature changes of various parts in the box body 1 and the electronic product to be tested in real time, wherein the airflow control mechanism 5 includes a first airflow control unit 6 and a second airflow control unit 7, which are used to control the air flow in the box body 1 to simulate the air flow during charging, so that the electronic product charging environment simulation box can effectively simulate the environmental conditions under various charging conditions, and provide the necessary environmental parameters and controls for the performance testing and reliability evaluation of electronic products.
[0034] Specifically, the first airflow control unit 6 is installed on the surrounding side of the test platform 2 to divide the inner cavity of the box 1 into a heating cavity 8 and a test cavity 9. It should be noted that, assuming that the test platform 2 is square, at least four first airflow control units 6 are installed, and the four first airflow control units 6 are distributed around the test platform 2. One side of the first airflow control unit 6 is fixedly connected to the test platform 2 and the other side is fixedly connected to the inside of the box 1, so that the gas in the heating cavity 8 can only enter the test cavity 9 through the first airflow control unit 6.
[0035] Next, a first air port 10 is provided on the side of the box body 1 close to the heating chamber 8, a first air flow control unit 6 is located on the side close to the first air port 10, a second air port 11 is provided on the top of the box body 1, and a second air flow control unit 7 is located on the side close to the second air port 11; a heating mechanism 3 is installed in the heating chamber 8, and the heating mechanism 3 heats the gas entering from the first air port 10. The density of the heated gas decreases, and the gas with a smaller density is subjected to an upward buoyancy force, which pushes the gas to move upward, so that the gas forms a laminar flow after passing through the first air flow control unit 6 and enters the test chamber 9, which helps to maintain the test chamber 9. The stability and uniformity of the airflow in the test cavity 9. After the air in the test cavity 9 passes through the second airflow control unit 7, it is discharged from the box 1 through the second air port 11, which helps to control and adjust the gas flow in the test cavity 9. The present application adjusts the airflow through the first airflow control unit 6 when the air enters the test cavity 9, and adjusts the air through the second airflow control unit 7 when the air is discharged from the test cavity 9. This helps to reduce the interference of external airflow on the inside of the simulation box, avoid the disturbance of airflow in the simulation box, create a relatively windless environment for the simulation environment, and ensure the stability and controllability of the simulation environment.
[0036] The above describes the working process of the electronic product charging environment simulation box. The key to regulating the airflow is the first airflow control unit 6 and the second airflow control unit 7. For ease of understanding, the first airflow control unit 6 and the second airflow control unit 7 are explained below: First, reference Figure 2 and Figure 3 The first airflow control unit 6 includes a first laminar flow plate 12 and a first metal mesh 13. The first metal mesh 13 is located on the side of the first laminar flow plate 12 close to the heating chamber 8. The function of the first metal mesh 13 is to break up the gas flow entering from the inside of the heating chamber 8 so that it can be more evenly distributed in the entire flow channel before passing through the first laminar flow plate 12. The first laminar flow plate 12 is installed between the inner wall of the box 1 and the test table 2. The first laminar flow plate 12 helps to ensure that the airflow can form a laminar state when passing through, that is, the flow is very stable and orderly, preventing the airflow from generating turbulence in the test chamber 9, so that a relatively windless environment can be simulated in the test chamber 9; it should be noted that the first laminar flow plate 12 and the first metal mesh 13 are tilted to form a trapezoidal structure with the test table 2. The tilted setting can help optimize the distribution of the airflow around the test table 2. In this way, the airflow may be more evenly distributed in the test area when passing through the flow plate and the metal mesh, reducing unnecessary turbulence and instability.
[0037] Second, reference Figure 4 and Figure 5 The second airflow control unit 7 includes a second laminar flow plate 14, a second metal mesh 15 and an auxiliary fan 16. The second metal mesh 15 is installed on the side of the second laminar flow plate 14 close to the second air port 11, and the auxiliary fan 16 is installed in the second air port 11. The function of the auxiliary fan 16 is to guide and control the airflow to direct the airflow in the test cavity 9 to one side of the second laminar flow plate 14. At the same time, the auxiliary fan 16 is also responsible for discharging the airflow processed by the second laminar flow plate 14 and the second metal mesh 15 from the second air port 11. The gas passes through the second laminar flow plate 14 and the second metal mesh 15 once to achieve precise control and regulation of the airflow, thereby ensuring that the required airflow conditions are generated inside the test cavity 9.
[0038] It should be noted that, refer to Figure 6In addition to simulating an environment with a temperature higher than the ambient temperature, the present application can also simulate an environment with a temperature lower than the ambient temperature. A refrigeration component 17 is installed at the bottom of the inner cavity of the box body 1 to refrigerate the gas entering from the first air port 10. The refrigerated gas is firstly regulated in temperature by a heating tube, and then the gas is dispersed by a first metal mesh 13, and then passes through a first laminar flow plate 12. The first laminar flow plate 12 plays a role in controlling and stabilizing the airflow during the passage of the airflow. After passing through the first laminar flow plate 12, the refrigerated gas enters the test cavity 9. The refrigeration component 17 can be a compressor refrigeration or a semiconductor refrigeration plate refrigeration. Compression refrigeration uses a compressor to circulate the refrigerant, and achieves the cooling effect through the process of compression, condensation, expansion and evaporation. The throttling component can be a capillary, a thermal expansion valve or an electronic expansion valve; semiconductor refrigeration plate refrigeration achieves cooling or heating through the Peltier effect of the semiconductor.
[0039] Reference Figure 6 The heating mechanism 3 includes a heating seat 18 installed at the bottom of the box body 1 and a plurality of heating tubes 19 installed on the heating seat 18. The heating seat 18 is used to support and fix the heating tubes 19. The position and design of the heating seat 18 can ensure that the heating tubes 19 can be stably installed and operated. The function of the heating tubes 19 is to provide heat energy for heating the air in the heating cavity 8. The heating tubes 19 are usually heated by electric energy, and the temperature and heat output can be adjusted as needed so that the heating mechanism 3 can provide the required heating function inside the box body 1. In order to monitor the temperature of the heating tubes 19, the first temperature sensor 21 in the temperature detection mechanism 4 is installed on the side of the heating seat 18 close to the heating tubes 19.
[0040] Further, refer to Figure 6 In order to ensure that the temperature distribution of the heating tube 19 is more uniform during operation and avoid local overheating or uneven temperature, a ceramic gasket 20 is installed between the heating seat 18 and the heating tube 19. The ceramic gasket 20 usually has good thermal isolation performance. The ceramic gasket 20 can reduce the heat conduction between the heating seat 18 and the heating tube 19. The ceramic gasket 20 can protect the heating tube 19 from damage or thermal stress caused by direct contact.
[0041] Reference Figure 5 and Figure 6The temperature detection mechanism 4 is used to detect the temperature of the heating cavity 8 and the test cavity 9. Specifically, the temperature testing mechanism includes a first temperature sensor 21 and a second temperature sensor 22. The first temperature sensor 21 is installed on the side of the heating seat 18 close to the heating tube 19, and is mainly used to monitor and measure the temperature of the heating tube 19. The second temperature sensor 22 is installed on the side wall of the box body 1, and is used to monitor and measure the temperature in the test cavity 9. The first temperature sensor 21 and the second temperature sensor 22 can be used to fully monitor and control the heating process and the detection environment temperature. The first temperature sensor 21 ensures that the heating tube 19 operates stably within the required temperature range, and the second temperature sensor 22 provides data on the overall temperature inside the test cavity 9 to help adjust the heating process or verify whether the temperature conditions of the experimental environment meet the requirements.
[0042] Reference Figure 1 An operating door 23 is installed on the side wall of the box 1. The operating door 23 allows the user to easily open and close the box 1, which is convenient for internal operation, maintenance or adjustment of the equipment. This is especially important for equipment that requires frequent entry and exit or regular maintenance. If adjustment is required during the test, if the entire operating door 23 is opened, it is easy to affect the temperature inside the box 1 and damage the simulated environment in the box 1. Therefore, an operating port 24 is opened on the operating door 23. The user can fine-tune the test product from the operating port 24 by opening the sealing plate 25. The sealing plate 25 is used to ensure that the operating port 24 is not used. Maintaining the sealing of the box 1 during use helps prevent unnecessary gas or liquid leakage and maintain the stability and safety of the internal environment of the box 1; further, in order to allow the user to directly observe and monitor the operation and experimental process inside the box 1, the box 1, the operating door 23 and the sealing plate 25 are all made of transparent materials. The transparent material allows the operator to visually inspect the layout, assembly and connection inside the box 1, thereby facilitating adjustment, maintenance or inspection work, which saves the time of opening and closing the operating door 23 and reduces the possible introduction of pollution or temperature fluctuations.
[0043] The metal mesh can effectively disperse the gas over a larger surface area by utilizing the size, density and surface characteristics of its mesh holes, thereby increasing the contact area between the gas and the mesh, evenly distributing the hot air flow to each pore and then discharging it, thereby improving the uniformity of heating.
[0044] The laminar plate generates a certain airflow through the fan, so that the air flows in the air duct and forms a stable laminar flow under the action of the laminar plate, ensuring the stability and uniformity of the air flow, thereby avoiding the generation of vortices.
[0045] The implementation principle of an electronic product charging environment simulation box in the embodiment of the present application is as follows: the box body 1 is the main structure of the entire simulation environment, the interior of the box body 1 is divided into a heating cavity 8 and a test cavity 9, the test table 2 is located in the box body 1, and is used to place the electronic product to be tested, the heating mechanism 3 is installed in the heating cavity 8 and is responsible for heating the air entering from the first air port 10, the temperature detection mechanism 4 is used to monitor the temperature changes inside the heating cavity 8 and the test cavity 9 to ensure that the ambient temperature meets the set simulation conditions, and the airflow control mechanism 5 includes a first airflow control unit 6 and a second airflow control unit 7, which are respectively located in the box body 1. The first airflow control unit 6 is installed on the side of the test platform 2 to control the direction and properties of the airflow. The heated gas forms a laminar flow through the first airflow control unit 6 and enters the test cavity 9, which helps to maintain the stability and uniformity of the airflow in the test cavity 9. The second airflow control unit 7 is installed on the top of the box 1 near the second air port 11. After passing through the second airflow control unit 7, the air in the test cavity 9 is discharged from the box 1 through the second air port 11, which helps to control and regulate the gas flow in the test cavity 9, reduce the interference of external airflow on the inside of the simulation box, and ensure the stability and controllability of the simulation environment.
