[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a high and low temperature test chamber with cascade cooling, including a test chamber body 1, a control box 2 installed on the side of the test chamber body 1, a cover 3 movably connected to one side of the surface of the control box 2, a heat dissipation mechanism 4 provided on one side of the inner surface of the control box 2, and a fixing mechanism 5 provided on one side of the surface of the control box 2.

[0023] The heat dissipation mechanism 4 includes a temperature sensor 401. A ventilation slot 402 is provided on one side of the surface of the control box 2. A support plate 403 is fixedly connected to one side of the inner surface of the control box 2. A ventilation hole 404 is provided on one side of the surface of the box cover 3. A protective frame 405 is fixedly connected inside the ventilation slot 402. A protective net 406 is installed inside the protective frame 405. A drive motor 407 is installed on one side of the surface of the support plate 403. One end of the drive motor 407 is connected to a cooling fan 408. Through the arrangement of the temperature sensor 401, ventilation slot 402, support plate 403, ventilation hole 404, protective frame 405, protective net 406, drive motor 407, and cooling fan 408, during use, the drive motor 407, when energized, drives the cooling fan 408 to rotate. The cooling fan 408 expels hot air from inside the control box 2 through the ventilation slot 402. At this time, the air pressure inside the control box 2 decreases, and the air pressure outside the control box 2... Air flows into the control box 2 through the ventilation hole 404. As the drive motor 407 continuously drives the cooling fan 408 to rotate, the air inside the control box 2 circulates, thereby reducing the temperature inside the control box 2. The protective frame 405, which is equipped with a protective net 406, is fixed inside the ventilation slot 402, which can prevent users from touching the cooling fan 408 and getting injured when it is rotating. The temperature sensor 401 is electrically connected to the drive motor 407. The temperature sensor 401 senses the temperature inside the control box 2 and adjusts the speed of the drive motor 407 accordingly. When the temperature sensor 401 senses that the temperature inside the control box 2 is high, the drive motor 407 drives the cooling fan 408 to rotate quickly. When the temperature sensor 401 senses that the temperature inside the control box 2 is low, the drive motor 407 slows down the speed of the cooling fan 408, thereby reducing the energy consumption of the drive motor 407.

[0024] Furthermore, a temperature sensor 401 is installed on one side of the inner surface of the control box 2. The temperature sensor 401 is electrically connected to the drive motor 407. By setting the temperature sensor 401, during use, the temperature sensor 401 is electrically connected to the drive motor 407. The temperature sensor 401 can adjust the speed of the drive motor 407 by sensing the temperature inside the control box 2, thereby adjusting the speed of the cooling fan 408. By adjusting the drive motor 407, the energy consumption of the drive motor 407 is reduced.

[0025] Furthermore, the cooling fan 408 is aligned with the ventilation slot 402.

[0026] Furthermore, the fixing mechanism 5 includes a dovetail groove 501, a limiting hole 502 is formed on one side of the surface of the control box 2, a limiting groove 503 is formed inside the control box 2, a slider 504 is fixedly connected to one side of the surface of the box cover 3, a first magnet 505 is embedded inside the limiting groove 503, a second magnet 506 is fixedly connected to one end of the slider 504, a movable groove 507 is formed on one side of the surface of the slider 504, a return spring 508 is set inside the movable groove 507, and a locking block 509 is welded to one end of the return spring 508. Through the arrangement of the dovetail groove 501, the limiting hole 502, the limiting groove 503, the slider 504, the first magnet 505, the second magnet 506, the movable groove 507, the return spring 508, and the locking block 509, when in use, when it is necessary to open the box cover... When the cover 3 is fixed on the control box 2, the slider 504 with the cover 3 fixed on it is fitted into the dovetail groove 501. Then, the cover 3 is pushed to the other end of the dovetail groove 501. Then, the locking block 509 is pressed. At this time, the return spring 508 is compressed. When the locking block 509 is fitted into the movable groove 507, the cover 3 is pushed. At this time, the second magnet 506 connected to one end of the slider 504 is magnetically connected to the first magnet 505 fitted into the limiting groove 503. At the same time, the movable groove 507 is aligned with the limiting hole 502 opened on one side of the surface of the control box 2. At this time, the return spring 508 rebounds based on its characteristics, driving the locking block 509 to return to its original position. At this time, the locking block 509 is fitted into the limiting hole 502, thus the locking block 509 connects the control box 2 and the cover 3.

[0027] Furthermore, the dovetail groove 501 matches the size of the slider 504. By setting the dovetail groove 501, the dovetail groove 501 matches the size of the slider 504, so that the slider 504 can be easily fitted into the inside of the dovetail groove 501.

[0028] Furthermore, one end of the return spring 508 is welded to the slider 504 inside the movable groove 507. With the setting of the return spring 508, when in use, the return spring 508 will be compressed and deformed under pressure. When the pressure is removed, the return spring 508 will be spring-back deformed, so that the return spring 508 can drive the locking block 509 to move. When the movable groove 507 is aligned with the position of the limiting hole 502, the return spring 508 can drive the locking block 509 to return to its original position, thereby causing the locking block 509 to be fitted inside the limiting hole 502.

[0029] Furthermore, the size of the card block 509 matches that of the limiting hole 502.

[0030] Working principle: First, the slider 504, fixedly connected to one side of the cover 3, is fitted into the dovetail groove 501. Then, the cover 3 is pushed to make the slider 504 slide inside the dovetail groove 501. Then, the locking block 509 is pressed to fit into the movable groove 507. The cover 3 is pushed further. When the slider 504 slides to the other end of the dovetail groove 501, the first magnet 505 and the second magnet 506 are magnetically connected. At the same time, the movable groove 507 and the limiting hole 502 are aligned. At this time, the return spring 508 rebounds based on its characteristics, thereby driving the locking block 509 back to its original position, so that the locking block 509 fits into the limiting hole 502, thus fixing the cover 3 to one side of the control box 2. When overlapping... When the high and low temperature test chamber with refrigeration is in operation, the working components inside the control box 2 will generate heat. The drive motor 407 drives the cooling fan 408 to rotate. The cooling fan 408 exhausts the hot air inside the control box 2 through the ventilation slot 402. At this time, the low temperature air outside the control box 2 flows into the control box 2 through the ventilation hole 404. The continuous rotation of the drive motor 407 and the cooling fan 408 can circulate the air inside the control box 2, thereby reducing the temperature inside the control box 2. The temperature sensor 401 will adjust the speed of the drive motor 407 according to the temperature inside the control box 2, thereby adjusting the speed of the cooling fan 408. This can achieve energy-saving control on the basis of heat dissipation and reduce the energy consumption of the drive motor 407.
