[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0024] Reference Figure 1-5 A heat dissipation device for an oil-cooled screening test fixture includes a fixed plate 1. The top outer wall of the fixed plate 1 is provided with stepped grooves 2 distributed at equal intervals. The fixed plate 1 is provided with a fixing structure 3 in the stepped grooves 2. A partition plate 6 is installed at the center of the inner wall of the fixed plate 1. A heat-conducting plate 4 is installed on the bottom outer wall of the fixed plate 1. The heat-conducting plate 4 is provided with heat dissipation structures 5 at each of the stepped grooves 2.

[0025] The heat dissipation structure 5 includes heat-conducting fins 7 evenly spaced on the bottom outer wall of the heat-conducting plate 4, a bracket 8 installed on the bottom outer wall of the heat-conducting plate 4 at the heat-conducting fins 7, a motor 9 installed at the center of the bottom outer wall of the bracket 8, and a fan blade 10 installed on the outer wall of the output shaft of the motor 9. When the motor 9 on the bracket 8 is started, it drives the fan blade 10 to rotate, so that the air inlet 14 in the airflow protection shell 13 enters and contacts the heat-conducting fins 7, carrying away the temperature of the oil and maintaining the temperature balance of the oil.

[0026] A protective shell 13 is installed on the bottom outer wall of the heat-conducting plate 4 at the heat-conducting fin 7, and an air inlet 14 is provided on the outer wall of the protective shell 13.

[0027] The top of the partition plate 6 and the top of the heat-conducting plate 4 are both inclined structures, and a return hole 20 is opened at the center of the stepped groove 2 on one end of the outer wall of the partition plate 6. The temperature generated by the test element body 17 during testing is transferred to the heat-conducting fin 2 19. The flowing oil carries away the temperature on the heat-conducting fin 2 19, that is, it cools down the test element body 17 and ensures the stability of the test.

[0028] A peristaltic pump 11 is installed on one side of the outer wall of the fixed plate 1 at the center of the stepped groove 2, and a circulation pipe 12 is provided in the peristaltic pump 11. The other end of the circulation pipe 12 is connected to the top of the partition plate 6 and the top of the heat-conducting plate 4 respectively. The inclination direction of the partition plate 6 and the heat-conducting plate 4 is as follows: Figure 5 The peristaltic pump 11, circulation pipe 12, and return hole 20 facilitate the circulation of oil and make it easy to use. Example

[0029] Reference Figure 4 The fixing structure 3 includes a mounting plate 15 installed on the outer wall of the stepped groove 12, a stepped groove 2 16 opened at the center of the mounting plate 15, a test element body 17 placed in the stepped groove 2 16, and a fixing frame 18 installed at the center of the top outer wall of the mounting plate 15. The fixing frame 18 is installed on the mounting plate 15 to fix the test element body 17 in the stepped groove 2 16 of the mounting plate 15, which facilitates the fixing of the element. The heat-conducting fins 2 19, together with the silicone grease, transfer the temperature of the test element body 17 to the heat-conducting fins 2 19, which is convenient for use and facilitates heat dissipation.

[0030] The bottom outer wall of the mounting bracket 18 contacts the outer wall of the test element body 17, and the bottom outer wall of the mounting plate 15 is equipped with heat-conducting fins 19 at the center of the stepped groove 16. The mounting bracket 18 is installed on the mounting plate 15 to fix the test element body 17 in the stepped groove 16. The mounting plate is flipped over to install the heat-conducting fins 19 on the outer wall of the mounting plate 15, which facilitates fixing the test element body 17.

[0031] The motor 9 and the peristaltic pump 11 are connected to a switch via wires, and the switch is connected to a power source via wires.

[0032] Working principle: In use, the test element body 17 to be tested is placed in the stepped groove 16. The fixing bracket 18 is installed on the mounting plate 15 to fix the test element body 17 in the stepped groove 16. The mounting plate is flipped over to install the heat-conducting fins 19 on the outer wall of the mounting plate 15. Silicone grease is applied between the heat-conducting fins 19 and the test element body 17 to increase thermal conductivity. The heat-conducting fins 19 are installed downwards in the stepped groove 2 on the mounting plate 15. A wiring harness is used to connect to the test element body 17 to perform high-temperature load testing. Oil is added to the top of the heat-conducting plate 4 in the mounting plate 15. After the peristaltic pump 11 is started, the oil on the top of the heat-conducting plate 4 is transported through the circulation pipe 12. At the top of the partition plate 6, the oil moves on the top of the partition plate 6 and returns to the top of the heat-conducting plate 4 through the return hole 20. During this process, the oil comes into contact with the second heat-conducting fin 19. The temperature generated by the test element body 17 during testing is transferred to the second heat-conducting fin 19. The flowing oil carries away the temperature on the second heat-conducting fin 19, that is, it cools down the test element body 17 and ensures the stability of the test. When the oil is in the heat-conducting plate 4, the oil is transferred to the first heat-conducting fin 7 through the heat-conducting plate 4. The motor 9 on the bracket 8 starts and drives the fan blade 10 to rotate, so that the air inlet 14 in the airflow protection shell 13 enters and comes into contact with the first heat-conducting fin 7, carrying away the temperature of the oil and maintaining the temperature balance of the oil.
