Description

Technical Field

[0001] This utility model relates to the field of radiator testing technology, specifically a radiator testing device integrating dynamic fluid simulation technology. Background Technology

[0002] As we all know, with the increasing miniaturization and high performance of electronic devices, heat dissipation has become one of the key factors restricting device performance and lifespan. To ensure the stable operation of electronic devices under high load conditions, efficient heat sinks must be used to manage heat. However, traditional testing methods often struggle to accurately simulate the complex fluid dynamics in real-world applications, especially the impact of turbulence on heat dissipation efficiency. This leads to significant discrepancies between data obtained in laboratory environments and actual conditions, affecting the optimization of heat sink design. Previous testing devices typically required repeated disassembly and reassembly of the heat sink to adjust its angle or position for turbulence testing from different directions. This approach is not only time-consuming and labor-intensive but also increases the possibility of experimental errors. In some application scenarios, it is insufficient to focus solely on the overall heat dissipation performance of the heat sink; it is also necessary to understand the heat dissipation effect of its local areas. However, traditional testing methods struggle to effectively and accurately heat and test different parts of the heat sink. Therefore, it is necessary to propose solutions to this technical problem.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model is a radiator testing device integrating dynamic fluid simulation technology, including a sealed chamber 1. An assembly platform 2 and a temperature detector 3 are provided inside the sealed chamber 1. A rotation mechanism is provided between the assembly platform 2 and the sealed chamber 1. A controller 4, an exhaust mechanism, and a turbulence mechanism are provided on the sealed chamber 1. A heating mechanism is provided in the sealed chamber 1, including a first heating plate 5 and a second heating plate 6. A lifting mechanism 7 is provided between the first heating plate 5 and the top of the sealed chamber 1. A heating component is provided at the bottom of the second heating plate 6, and a metal flexible hose 8 is provided between the second heating plate 6 and the controller 4. The bottom of the heating plate 6 is provided with an adsorption groove, and the top of the adsorption groove is provided with a sealing groove. A threaded hole is provided between the top of the sealing groove and the top of the second heating plate 6. A threaded post 9 is provided on the threaded hole, and a sealing plug 10 is provided between the bottom of the threaded post 9 and the sealing groove. In this embodiment, the heat sink to be tested is assembled using the assembly table 2, and then the first heating plate 5 is pressed against the heat sink using the lifting mechanism 7. Then, the first heating plate 5 is heated, and then a turbulence test is performed using a turbulence mechanism. The temperature of the first heating plate 5 is detected by a temperature detector 3, thereby realizing the detection of different turbulence conditions. To assess the heat dissipation efficiency of the radiator on the first heating plate 5 under normal conditions, when testing localized heat dissipation, the second heating plate 6 can be placed against the radiator by bending the metal flexible hose 8. The bottom end of the second heating plate 6 is then placed against the radiator surface via an adsorption groove. Rotating the threaded column 9 within the threaded hole causes the sealing plug 10 to move upwards within the sealing groove, creating an air pressure difference between the adsorption groove and the outside air. This allows the second heating plate 6 to be flexibly and securely placed on the radiator. Finally, activating the heating assembly locally heats the radiator, thus achieving efficient heat dissipation. In the local heat dissipation test of the radiator, when the turbulence mechanism is in use, the gas in the sealed chamber 1 is discharged through the exhaust mechanism, which facilitates the turbulence test. When it is necessary to adjust the radiator for turbulence testing at different angles, the lifting mechanism 7 is moved upward to make the first heating plate 5 leave the radiator, and the threaded column 9 is rotated to make the sealing plug 10 move downward, thereby releasing the second heating plate 6 from the radiator. Then, the angle of the radiator can be flexibly rotated by using the rotating mechanism, without the tedious steps of disassembling the radiator, readjusting the position and angle and then reassembling it. This allows for quick adjustment of the radiator angle, which is convenient for turbulence testing of radiators at different angles.

[0024] The aforementioned rotating mechanism can be any type of rotating device. To provide rotational stability for the assembly table 2, in this design, the rotating mechanism includes a drive motor 11 and a mounting slot. The mounting slot is located at the bottom of the inner wall of the sealing chamber 1, and a bearing seat 12 is provided on the mounting slot. A heat insulation plate 13 is provided between the bearing seat 12 and the assembly table 2. The drive motor 11 is installed at the bottom of the sealing chamber 1, and the output end of the drive motor 11 passes through the mounting slot and is connected to the heat insulation plate 13. By controlling the output end of the drive motor 11 to rotate the heat insulation plate 13, the heat insulation plate 13 stably drives the assembly table 2 to rotate at an angle through the bearing seat 12, thereby flexibly adjusting the angle of the radiator on the assembly table 2. The heat insulation plate 13 can block heat transfer to the drive motor 11, ensuring that the drive motor 11 operates within the normal temperature range.

[0025] The above-mentioned exhaust mechanism can be any type of exhaust device. In order to facilitate the exhaust of air from the sealed chamber 1, in this solution, the exhaust mechanism includes an exhaust pipe 14. The exhaust pipe 14 is installed on the rear side of the sealed chamber 1. The exhaust pipe 14 on the rear side of the sealed chamber 1 can facilitate the exhaust of air from the sealed chamber 1 and facilitate air circulation.

[0026] The aforementioned turbulence mechanism can be any type of exhaust device. To facilitate turbulence testing, in this design, the turbulence mechanism includes an installation pipe 15 and a turbulence generator 16. The installation pipe 15 is installed on one side of the sealed chamber 1 and connects to the interior of the sealed chamber 1. An electric valve 17 is provided on the installation pipe 15. The turbulence generator 16 is installed on the installation pipe 15 and located inside the sealed chamber 1. It communicates with the outside world through the installation pipe 15. By opening the electric valve 17, the turbulence generator 16 can deliver outside air into the sealed chamber 1 for turbulence operation, which facilitates testing the heat dissipation efficiency of the radiator under different turbulence conditions.

[0027] To further improve the turbulence testing effect, in this solution, there are two symmetrically arranged turbulence mechanisms, which facilitate turbulence testing of the radiator in different directions.

[0028] In order to prevent the stable conduction of heat from the first heating plate 5 to the lifting mechanism 7, in this solution, a heat insulation plate 18 is provided between the output end of the lifting mechanism 7 and the first heating plate 5. The heat insulation plate 18 can prevent the stable conduction of heat from the first heating plate 5 to the lifting mechanism 7, thereby improving the stability of the lifting mechanism 7 during use by keeping it within the normal temperature range.

[0029] In order to test the local heat dissipation effect of the radiator, in this solution, there are two second heating plates 6 arranged symmetrically. The two symmetrically arranged second heating plates 6 can simultaneously heat two positions of the radiator locally, which facilitates further testing of the local heat dissipation effect of the radiator.

[0030] To improve the tightness of the second heating plate 6 adsorbed onto the radiator, in this design, a high-temperature resistant rubber sealing ring 19 is provided around the adsorption groove. The high-temperature resistant rubber sealing ring 19 can improve the tightness of the second heating plate 6 adsorbed onto the radiator. The high-temperature resistant rubber sealing ring 19 can function normally in high-temperature environments to ensure sealing performance and stability.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
