[0002] Integration testing, also called assembly testing or joint testing, is based on unit testing. All modules are assembled into a subsystem or system according to design requirements (such as according to the structure diagram) for integration testing. The comprehensive integrated unit is usually tested through a test chassis.

[0003] At present, when the test chassis is testing the integrated unit, the test equipment in the test chassis will generate a lot of heat during the power-on process, and it needs to be dissipated to avoid affecting the normal progress of the test. At present, heat dissipation holes are usually opened on the side walls of the test chassis to dissipate heat inside it, but when the test chassis is ventilated with the outside world, dust and impurities in the outside environment can easily enter the test chassis through the heat dissipation holes. Dust adheres to the test equipment and affects the service life of the test equipment.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 , a heat dissipation structure of a comprehensive integrated unit test chassis, including a test chassis body 1, in which a test device is installed to test the comprehensive integrated unit. This is a prior art and will not be described in detail herein. Heat dissipation openings 2 are provided through the side walls at both ends of the test chassis body 1, and first dustproof nets 3 are installed in the two heat dissipation openings 2. The first dustproof nets 3 can filter the air entering the test chassis body 1 to reduce the dust from entering the test chassis body 1. U-shaped covers 4 are installed on the side walls at both ends of the test chassis body 1, and the two U-shaped covers 4 are respectively opposite to the two heat dissipation openings 2. Flanges 5 are provided on the upper and lower side walls of the U-shaped cover 4, and the two flanges 5 are connected to the side walls of the test chassis body 1 by first screws. The U-shaped cover 4 can be stably installed on the outside of the test chassis body 1 by the cooperation of the first screws and the flanges 5;

[0022] The front and rear side walls of the two U-shaped cover shells 4 are detachably connected with dustproof components, and the dustproof components include two stoppers 6 fixedly connected to the inner side walls at the upper and lower ends of the U-shaped cover shell 4, and an annular frame 7 that abuts against the two stoppers 6 is slidably connected inside the U-shaped cover shell 4, and the stopper 6 can block the annular frame 7, so that the annular frame 7 cannot continue to move into the U-shaped cover shell 4, and a second dustproof net 15 is installed in the annular frame 7, and the second dustproof net 15 can filter and block dust, thereby reducing dust from entering the U-shaped cover shell 4, and the upper and lower side walls of the U-shaped cover shell 4 are rotatably connected with baffles 8, and the two baffles 8 abut against the side walls of the annular frame 7, and the setting of the baffles 8 can fix the annular frame 7 to prevent the annular frame 7 from falling from the front side of the U-shaped cover shell 4;

[0023] A blowing assembly is installed in one of the U-shaped covers 4, and the blowing assembly includes a driving motor 9 installed on the inner side wall of one of the U-shaped covers 4, and a blowing fan blade 10 opposite to the heat dissipation opening 2 is installed at the end of the output shaft of the driving motor 9. The driving motor 9 drives the blowing fan blade 10 to rotate, which can accelerate the air circulation in the test chassis body 1 through the two heat dissipation openings 2, thereby dissipating the heat inside the test chassis body 1;

[0024] The rear side wall of the test chassis body 1 is installed with an auxiliary heat dissipation component, which includes a heat conducting plate 11 connected to the rear side wall of the test chassis body 1 by a second screw, and a plurality of heat dissipation fins 12 are installed on the side wall of the heat conducting plate 11. The heat conducting plate 11 is in contact with the rear side wall of the test chassis body 1, and can work together with the heat dissipation fins 12 to take away the heat in the test chassis body 1, and the heat dissipation fins 12 extend horizontally, so that the spacing between the adjacent heat dissipation fins on both sides can form a channel for air circulation, which is beneficial for the heat dissipation fins 12 to dissipate heat and take away the heat in the test chassis body 1. The rear side wall of the test chassis body 1 is connected with a U-shaped protective plate 13 covering the outside of the plurality of heat dissipation fins 12. The U-shaped protective plate 13 can protect the heat dissipation fins 12 and reduce the safety hazards of the heat dissipation fins 12. The side wall of the U-shaped protective plate 13 is fixedly connected with a plurality of connection blocks 14, and the plurality of connection blocks 14 are connected to the rear side wall of the test chassis body 1 by a third screw, so as to facilitate the installation and disassembly of the U-shaped protective plate 13.

[0025] The functional principle of the utility model can be explained through the following operation modes:

[0026] In the utility model, when the heat dissipation structure of the comprehensive integrated unit test chassis is working, the test equipment installed inside the test chassis body 1 tests the comprehensive integrated unit, and the two heat dissipation ports 2 on both sides of the test chassis body 1 form a channel for air circulation to dissipate heat inside the test chassis body 1. Starting the drive motor 9 drives the fan blades 10 to rotate, which can accelerate the air circulation inside the test chassis body 1 and dissipate heat inside the test chassis body 1. The second dustproof net 15 can preliminarily filter the air entering the test chassis body 1 to reduce most of the dust in the air from entering the test chassis body 1. The first dustproof net 3 can further reduce the dust in the air from entering the test chassis body 1. The heat conducting plate 11 and the heat dissipating fins 12 can further take away the heat in the test chassis body 1 and effectively dissipate heat inside the test chassis body 1.

[0027] Since the second dustproof net 15 performs preliminary filtering, more dust will adhere to it. The baffle plate 8 is rotated so that it no longer blocks the annular frame 7, and the annular frame 7 can be taken outward, which facilitates the cleaning or replacement of the second dustproof net 15. After cleaning, the annular frame 7 is placed in the U-shaped cover 4 and abutted against the two blocks 6. The baffle plate 8 is rotated so that it abuts against the front side wall of the annular frame 7. The baffle plate 8 and the block 6 work together to fix the annular frame 7 in the U-shaped cover 4, completing the installation work. The U-shaped cover 4 is removed by removing the first screw, and the first dustproof net 3 can be cleaned or replaced.
