[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0028] The following is a reference to the appendix. Figure 1 To be continued Figure 7 This invention describes a novel testing device.

[0029] Existing testing equipment, due to its highly integrated modules, suffers from poor ventilation and heat dissipation, which leads to a decline in the performance of the testing equipment, a reduction in operating speed, and in severe cases, functional abnormalities or malfunctions.

[0030] Therefore, this utility model provides a novel testing device, such as... Figures 1-3As shown, the structure includes a first structural layer 1, a heat dissipation layer 2 fixedly connected to the bottom of the first structural layer 1, and a second structural layer 3 fixedly connected to the end of the heat dissipation layer 2 away from the first structural layer 1. The heat dissipation layer 2 has a horizontally penetrating air duct 100, and a fan assembly 4 is provided on the air duct 100 to dissipate the heat transferred from the first structural layer 1 and the second structural layer 3 to the heat dissipation layer 2. Specifically, the structure is divided into three layers: upper, middle and lower, with the heat dissipation layer 2 located in the middle. After the heat from the first structural layer 1 and the second structural layer 3 is transferred to the heat dissipation layer 2, the heat dissipation layer 2 dissipates heat through the air duct 100, thereby solving the problem of poor ventilation and heat dissipation after the module is highly integrated.

[0031] Preferably, the air duct 100 includes an air inlet end and an air outlet end, and the fan assembly 4 includes a first fan group 401 and a second fan group 402. The first fan group 401 is installed at the air inlet end, and the second fan group 402 is installed at the air outlet end. The air blowing direction of the first fan group 401 is the same as that of the second fan group 402. Specifically, the fan adopts the method of "blowing air at the air outlet end and drawing air at the air inlet end" to generate airflow in a specific direction, accelerate the airflow speed in the air duct 100, and uniformly cool the first structural layer 1 and the second structural layer 3, thereby improving the heat dissipation efficiency.

[0032] Preferably, the heat dissipation layer 2 includes an upper heat dissipation plate 201 and a lower heat dissipation plate 202. The opposite ends of the upper heat dissipation plate 201 and the lower heat dissipation plate 202 are fixedly connected by a sealing plate 203, thereby forming a through air duct 100 with the upper heat dissipation plate 201, the lower heat dissipation plate 202 and the sealing plate 203. A connecting post 204 is provided at both opposite ends of the air duct 100. The first fan group 401 is fixedly connected to the connecting post 204 at the air inlet end by means of a thread, and the second fan group 402 is fixedly connected to the connecting post 204 at the air outlet end by means of a thread.

[0033] Preferably, an upper heat dissipation fin 2011 is fixedly connected to the lower end face of the upper heat dissipation plate 201, and a lower heat dissipation fin 2021 is fixedly connected to the lower end face of the lower heat dissipation plate 202. Specifically, adding fin structures to the upper heat dissipation plate 201 and the lower heat dissipation plate 202 further improves the heat dissipation efficiency of the heat dissipation layer 2, thereby ensuring that the temperature of the first structural layer 1 and the second structural layer 3 is not too high.

[0034] As a preferred option, such as Figure 4 As shown, the first structural layer 1 includes a first main module 101, and a top cover plate 102 is sealed and installed on the top of the first main module 101. The first main module 101 is used to install multiple functional modules 200, and the first main module 101 is fixedly connected to the heat dissipation layer 2.

[0035] As a preferred option, such as Figure 5As shown, the first main module 101 has a sealing strip groove 1011 on its structural edge. A double-peak shielding strip 103 is provided in the sealing strip groove 1011. The upper cover plate 102 presses the double-peak shielding strip 103 against the first main module 101 and fixes it in place, so that the first structural layer 1 forms a double seal for air and electromagnetic fields, thereby meeting the usage requirements of harsh environments and complex electromagnetic environments.

[0036] Preferably, the main module and the upper cover plate 102 of the first structural layer 1 are made of aluminum. Specifically, the aluminum structure includes aluminum alloys, etc., to ensure good shielding of the structure and effectively prevent microwave leakage.

[0037] As a preferred option, such as Figure 6 As shown, the first structural layer 1 also includes a metal shielding box 300. The functional module 200 is installed inside the metal shielding box 300. The metal shielding box 300 is fixedly connected to the first main body module 101, so that each functional module 200 is shielded internally first to ensure electromagnetic sealing. Optionally, in some application scenarios where electromagnetic sealing is more stringent, in order to further improve electromagnetic sealing, multiple layers of metal shielding boxes 300 can be stacked and packaged with the functional module 200 and then fixedly connected to the first main body module 101. For example, a functional module 200 is installed inside the first metal shielding box 300, and then the first metal shielding box 300 is installed inside a second metal shielding box 300 with a larger size to achieve a more stringent electromagnetic sealing effect.

[0038] As a preferred option, such as Figure 7 As shown, the second structural layer 3 includes a second main module 301. A base plate 302 is sealed and installed at the bottom of the second main module 301. The second main module 301 is used to install multiple functional modules 200. The second main module 301 is fixedly connected to the heat dissipation layer 2. Lifting handles 303 are fixedly connected to the opposite sides of the second main module 301 to facilitate lifting by the operator.

[0039] The sealing structure of the second structural layer 3 is the same as that of the first structural layer 2, and will not be described again here.

[0040] Preferably, the first structural layer 1 is equipped with a lighter functional module 200, and the second structural layer 3 is equipped with a heavier functional module 200, thereby lowering the center of gravity of the equipment and making the overall equipment less prone to slippage.

[0041] Preferably, the novel testing equipment of this utility model embodiment is fixed by screws, thereby increasing the natural frequency of the whole machine and making the natural frequency outside the excitation frequency range.

[0042] Preferably, the bottom surface of the base plate 302 is provided with anti-slip texture and anti-slip pad, thereby further ensuring that the equipment is not prone to slipping.

[0043] This utility model adopts an integrated design, dividing the structure into three layers: upper, middle and lower. Functional modules 200 with similar functions are integrated into one layer, and each functional module 200 and component is easy to disassemble and maintain. This not only solves the problem of poor ventilation and heat dissipation after the modules are highly integrated, but also solves the problems of electromagnetic compatibility and environmental adaptability. It greatly improves the "three-in-one" degree of the equipment, effectively reduces the size and weight of the equipment, and enables single-person handling and follow-up support.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
