During operation, it can forcefully draw cold air into the interior of the test chamber 1, effectively cooling the heat-generating components inside the chamber and ensuring stable operation of the equipment. Screws 203 are threadedly connected to the four corners of the rear side of the two fans 202. With the fastening effect of the screws 203, the fans 202 are firmly fixed to the rear side of the test chamber 1. Multiple ventilation holes 204 are opened on the bottom of the left and right sides of the test chamber 1. Air can flow in from the bottom ventilation holes 204, forming good convection with the cold air introduced by the fans 202, which greatly increases the ventilation. Multiple heat dissipation fins 205 are also fixedly connected to the top of the left and right sides of the test chamber 1, increasing the heat dissipation area and further enhancing the heat dissipation effect, ensuring the heat dissipation performance of the test chamber 1 in all aspects.
[0035] Reference Figure 1 and Figure 2 The test box 1 has fixed posts 14 at the four corners of the top, and pull rings 15 are fixedly connected to the top of each of the fixed posts 14. This allows for quick loading, unloading and transportation of the entire machine in conjunction with a crane. A mouse 16 is magnetically connected to the top right side of the test box 1. The mouse 16 is electrically connected to the monitor 4 and is used to control the monitor 4. A control panel 17 is fixedly connected to the top right side of the test box 1. Multiple buttons 18 are fixedly connected to the top of the control panel 17 for controlling the device.
[0036] Specifically, fixed posts 14 are fixedly connected to the four corners of the top of the test box 1. Each fixed post 14 is connected to a pull ring 15 at the top. The pull ring 15 can be used with a crane to enable quick loading and unloading of the whole machine during transportation, which greatly improves the handling efficiency. On the top right side of the test box 1, a mouse 16 is installed by magnetic connection. The mouse 16 is electrically connected to the monitor 4, which makes it convenient for the operator to accurately control the monitor 4. A control panel 17 is also fixed on the top right side of the test box 1. The top of the control panel 17 is equipped with multiple buttons 18. These buttons 18 are used to control the device and make it convenient for users to operate the equipment.
[0037] Reference Figure 2 and Figure 3 A handle 19 is fixedly connected to the front left side of the cabinet door 6. The handle 19 has a smooth design to facilitate opening the cabinet door 6. Fixing brackets 20 are fixedly connected to the four corners of the bottom of the test box 1. Wheels 21 are rotatably connected to the inner side of the multiple fixing brackets 20 to facilitate the movement of the test box 1. Two fixing blocks 22 are fixedly connected to the top front side of the test box 1. The same pull rod 23 is fixedly connected to the front side of the two fixing blocks 22 to facilitate pulling the test box 1 to move.
[0038] Specifically, a handle 19 is fixedly connected to the front left side of the cabinet door 6. It adopts a smooth design to provide users with a comfortable and convenient gripping experience, so as to easily open the cabinet door 6. Fixing brackets 20 are fixedly connected to the four corners at the bottom of the test box 1. The inner side of these fixing brackets 20 is equipped with flexibly rotating wheels 21. The presence of wheels 21 allows the test box 1 to move easily. Two fixing blocks 22 are fixed on the top front side of the test box 1, which are connected to a pull rod 23, making it easier and less strenuous to pull the test box 1.
[0039] Working principle: The operator adjusts the display 4 to a suitable angle using the rotatable bracket 3 on the top rear side to clearly view various test data and information. The cabinet door 6 is opened smoothly with the help of hinge 5. Inside the test box 1, the operator takes out the tools or equipment required for testing from the drawer 9. The slow-closing function of the drawer 9 protects the items inside. The power distribution automation equipment to be tested is connected to the test node of the PXIe board in the cabinet through the test interface 12 on the bottom left side of the cabinet door 6 to achieve electrical connection. If the equipment needs to be tested for network communication, a network connection can be established through the Ethernet port 11, which is treated with anti-oxidation and clearly marked. If data transmission or power supply is required, the USB interface 13 on the top rear left side can be used for wiring. The test data is fed back to the display 4 in real time.
[0040] Furthermore, the two air inlets 201 on the rear side of the test chamber 1 serve as entrances for cold air from the outside. The outer walls of the two fans 202 are fixed inside the air inlets 201. When the fans 202 operate, their powerful suction creates a negative pressure zone. Under the influence of this pressure difference, cold air from the outside is forcefully drawn into the test chamber 1 through the air inlets 201, directly cooling the heating elements. Multiple ventilation openings 204 on the left and right sides of the bottom of the test chamber 1 allow the cold air introduced by the fans 202 to exchange heat with the heating elements inside the chamber, increasing its temperature. The lower density of the hot air causes it to rise. The presence of the bottom ventilation openings 204 ensures a continuous supply of cold air from the bottom, creating natural convection with the rising hot air, thus increasing the air circulation speed within the test chamber 1 and allowing more cold air to enter. The heat dissipation fins 205, which are fixedly connected to the top of the left and right sides of the test chamber 1, are made of high thermal conductivity material. After the heat exchange between the air inside the chamber and the heat-generating element, part of the heat is transferred to the metal shell of the test chamber 1 through thermal conduction, and then to the heat dissipation fins 205. The heat dissipation fins 205 have a large surface area, and the better the heat dissipation effect, the better the heat dissipation effect. In the natural environment, there is a temperature difference between the heat dissipation fins 205 and the surrounding air. The heat will be continuously conducted to the air through thermal radiation and convection, which can remove the heat on the heat dissipation fins 205 more quickly, thereby further enhancing the heat dissipation performance of the entire test chamber 1 and ensuring the stable operation of the equipment inside the test chamber 1 in a suitable temperature environment.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
