[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Please see Figures 1-5 A high and low temperature pulse vibration integrated test chamber includes a frame 1, a moving track and a vibration mechanism 2. The frame 1 is slidably connected to the moving track. A test chamber 3 is provided inside the frame 1. A temperature control mechanism 4 is provided inside the frame 1. The vibration mechanism 2 includes a base 21, a lifting unit 22 and a vibration unit 23. The lifting unit 22 is fixedly installed in the base 21 and the vibration unit 23 is fixedly installed at the output end of the lifting unit 22.

[0023] As an embodiment of the present invention, the moving track needs to be laid on the ground in advance, and the frame 1 and the moving slide rail can be connected by pulleys. Preferably, a lockable pulley can be selected to lock the frame 1.

[0024] Furthermore, the vibration mechanism 2 is set between the moving tracks, and the frame 1 can slide to move above the vibration mechanism 2. The vibration mechanism 2 includes a base 21, a lifting unit 22 and a vibration unit 23. The base 21 is fixedly set between the moving tracks, the lifting unit 22 is fixedly set inside the base 21, and the vibration unit 23 is fixedly set at the output end of the lifting unit 22. The lifting unit can drive the vibration unit 23 to move upward, and then it can pass through the square slot opened on the frame 1 to contact the cold plate, driving the cold plate to maintain vibration to simulate the driving environment.

[0025] It should be noted that cold plates typically vibrate at small amplitudes during operation. Therefore, small amplitude vibrations are simulated during testing. If large amplitude vibrations or mixed amplitude vibrations need to be tested, other equipment is required.

[0026] As a further embodiment provided by this utility model, such as Figure 3As shown, the vibration mechanism 2 also includes a mounting base 24, which is fixedly installed at the output end of the lifting unit 22. The vibration unit 23 is disposed inside the mounting base 24. Specifically, the mounting base 24 is a hollow structure, and the vibration unit 23 is fixedly installed inside the hollow structure of the mounting base 24. A locking unit 25 is fixedly installed on the mounting base 24, and the mounting base 24 is fixedly connected to the frame 1 through the locking unit 25.

[0027] As an embodiment provided by this utility model, such as Figure 4 As shown, the locking unit 25 includes a rotating plate 251, a limiting plate 252, and a locking ring 253. The rotating plate 251 is rotatably connected to the mounting base 24, the limiting plate 252 is slidably connected to one end of the rotating plate 251, and the locking ring 253 is threadedly connected to one end of the rotating plate 251. Specifically, as... Figure 4 As shown, a rotating rod 254 is fixedly mounted on the rotating plate 251. A through hole is provided on the outer wall of the mounting base 24. The rotating plate 251 is rotatably connected to the through hole via the rotating rod 254. A sliding groove is provided on the outer wall of the rotating rod 254. A limiting plate 252 is slidably connected to the rotating rod 254 via the sliding groove. A thread is provided at the end of the rotating rod 254 away from the rotating plate 251. A locking ring 253 is threadedly connected to the end of the rotating rod 254 away from the rotating plate 251. Figure 5 As shown, when vibration is required, the mounting base 24 is raised via the lifting unit 22. Rotating the rotating rod 254 causes the rotating plate 251 and the limiting plate 252 to rotate, positioning their ends on opposite sides of the frame 1. Then, the locking ring 253 is tightened to securely connect the mounting base 24 and the frame 1. When the frame 1 needs to be moved, simply rotate the locking ring 253 in the opposite direction to allow the limiting plate 252 to slide again within the groove. Then, rotating the rotating rod 254 causes the rotating plate 251 to rotate and the limiting plate 252 to rotate back into the mounting base 24, allowing the mounting base 24 to be raised or lowered. To reduce the impact of vibration from the mounting base 24 on the frame 1, cushioning rubber can be installed on the rotating plate 251 and the limiting plate 252.

[0028] As an embodiment provided by this utility model, such as Figure 2 As shown, the temperature control mechanism 4 includes a heating unit 41, a cooling unit 42, an air inlet 43, an air outlet 44, a first connecting pipe 45, a second connecting pipe 46, and a third connecting pipe 47. The air inlet 43 and the air outlet 44 are both located on the inner wall of one side of the test chamber 3. The heating unit 41 and the cooling unit 42 are both located within the frame 1. The first connecting pipe 45 is connected at both ends to the air inlet 43 and the heating unit 41, respectively. The second connecting pipe 46 is connected at both ends to the air outlet 44 and the cooling unit 42, respectively. The third connecting pipe 47 is connected at both ends to the heating unit 41 and the cooling unit 42, respectively. A temperature sensor is installed inside the test chamber 3 to detect the internal temperature of the test chamber 3.

[0029] As an embodiment of the present invention, the refrigeration unit 42 can be an evaporator, and the heating unit 41 can be a heating tube, used to refrigerate or heat the air.

[0030] Furthermore, an explosion-proof pressure relief door 5 is fixedly installed on the top of the frame 1 to prevent excessive pressure inside the test chamber 3 after the cold plate is damaged during the test.

[0031] As a further embodiment provided by this utility model, such as Figure 1 As shown, a liquid interface is provided on the frame 1, which can be connected to a pulse testing device. The liquid interface is then connected to a cold plate, allowing the test liquid to be input into the cold plate, and the pulse testing device to test the interior of the cold plate.

[0032] Specifically, vibration mechanism 2 is a vibration test bench.

[0033] In this invention, the frame 1 can move freely on a moving track. By moving the frame 1, it is convenient to place the cold plate to be tested inside the frame 1. After the cold plate is placed inside the test chamber 3 of the frame 1, the frame 1 is moved again above the vibration mechanism 2. The vibration mechanism 2 simulates the vibration of the cold plate. At the same time, the temperature control mechanism 4 controls the temperature inside the test chamber 3. The vibration mechanism 2 and the temperature control mechanism 4 can simulate the actual operating environment of the cold plate, thereby enabling efficient testing and improving testing efficiency.

[0034] Those skilled in the art will understand that other similar connection methods can also achieve this utility model. For example, welding, bonding, or screwing.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
