Description

Technical Field

[0001] This application relates to the field of thermal vacuum testing technology, and in particular to a thermal vacuum integrated device for rigid test cables. Background Technology

[0002] The thermal vacuum testing system consists of an oil bath unit, a thermal vacuum tank, a heat sink, a cold plate, a vacuum pump and valve, connecting pipes, and a sheet metal frame. During use, the customer needs to place the test product on the cold plate, with the test cable passing through the test hole. After the door is closed, the product is placed in a vacuum environment. The oil bath unit delivers heat transfer oil to the cold plate and heat sink through the connecting pipes, raising and lowering the product temperature through conduction and radiation to obtain the test data required by the customer.

[0003] A standard hot vacuum chamber has a side-opening door, with a cold plate installed inside and test holes located on the left and right sides. It is only suitable for testing standard products with relatively soft test leads. If the test leads of a customer's product are too stiff, it cannot meet the requirements. Utility Model Content

[0004] To address the issue that traditional thermal vacuum testing systems cannot use rigid test cables, this invention provides an integrated thermal vacuum device for rigid test cables, comprising: a fixed frame, a movable frame, a vacuum chamber, a cold plate, and an oil bath unit. The front end of the fixed frame extends horizontally to form an installation platform, and the front end of the installation platform is provided with a first track. The vacuum tank includes a tank body and a door. The tank body is a barrel-shaped structure with an open front end and a hollow interior. It is set on the mounting platform, and a second track is provided inside the tank body. The door matches the opening of the tank body. The cold plate is fixedly connected to the door body, and a guide support wheel is provided below the cold plate. The guide support wheel is slidably connected to the second track. The movable frame is equipped with wheels at its bottom, and the movable frame is slidably connected to the first track via the wheels. The movable frame is also fixedly connected to the door. The oil bath unit is connected to and communicates with the cold plate.

[0005] In one possible implementation, the active frame is a hollow structure with a platform at the top; A fixing frame is provided above the platform, and the fixing frame is perpendicular to the surface of the platform. The mounting frame has an "H" shaped structure, with its bottom fixedly connected to the platform and its sidewalls fixedly connected to the door.

[0006] In one possible implementation, the sliding direction of the first track and the second track is the same as the opening direction of the tank.

[0007] In one possible implementation, there are two first tracks, which are arranged in parallel. The walking wheels are provided in four positions, which are symmetrically arranged at the four corners of the bottom of the movable frame.

[0008] In one possible implementation, the bath oil unit is embedded at the tail end of the fixed frame.

[0009] One possible implementation also includes: cold plate bath oil piping; The cold plate is connected to and communicates with the oil bathing unit through the cold plate oil bathing pipeline, and a drag chain is provided on the outside of the cold plate oil bathing pipeline. The cold plate oil bath pipeline uses a flexible hose.

[0010] In one possible implementation, one end of the cable chain is fixed to the movable frame, and the other end is fixed to the fixed frame; The cold plate oil bath pipeline is embedded inside the cable chain.

[0011] One possible implementation also includes: a heat sink and a heat sink bath oil pipeline; The heat sink is disposed inside the tank body; The heat sink is connected to the bath oil unit through the heat sink bath oil pipeline.

[0012] In one possible implementation, the panel of the door is provided with test holes for leading out rigid test cables.

[0013] One possible implementation also includes: a connecting fixing plate; One end of the connecting fixing plate is rotatably disposed on the side wall of the first track; The other end of the connecting fixing plate is provided with a buckle. When the door and the tank are closed, the connecting fixing plate is connected to the movable frame by the buckle.

[0014] The advantages of the integrated thermal vacuum device for rigid test cables in this application embodiment are: it effectively avoids the situation where the test product cable cannot be tested due to its rigidity, and also avoids the problems of large workload, high cost, difficult maintenance, and inconvenient product loading and unloading. Specifically, when the door opens and closes, the cold plate moves synchronously with the door, and the rigid cable can be led out from the test hole of the door, avoiding cable bending or breakage. It adapts to the testing requirements of rigid cables. The fixed frame, movable frame, vacuum tank, and oil bath unit form an integrated structure. The equipment does not need to be disassembled at the factory and can be used with only external water, electricity, and gas. This solves the problems of cumbersome disassembly and assembly and high labor costs of existing split equipment. The cold plate cooperates with the second track through guide support wheels, and the movable frame cooperates with the first track through walking wheels. The dual track guidance ensures that the door and cold plate move synchronously and smoothly, avoiding jamming or structural interference and improving the stability of the testing process.

[0023] like Figures 1-4 As shown, the thermal vacuum integrated device for rigid test cables in this application embodiment includes: a fixed frame 1, a movable frame 8, a vacuum tank, a cold plate 6, and an oil bath unit 2. The front end of the fixed frame 1 extends horizontally to form an installation platform. The front end of the installation platform is provided with a first track 5. The vacuum tank includes a tank body 3 and a door 4. The tank body 3 is a barrel-shaped structure with an open front end and a hollow interior. It is set on the installation platform, and the interior of the tank body 3 is provided with a second track 16. The door 4 matches the opening of the tank body 3. The cold plate 6 is fixedly connected to the door 4, and a guide support wheel is provided below the cold plate 6. The guide support wheel is slidably connected to the second track 16. The bottom of the movable frame 8 is provided with a traveling wheel. The movable frame 8 is slidably connected to the first track 5 through the traveling wheel. The movable frame 8 is fixedly connected to the door 4. The oil bath unit 2 is connected and communicates with the cold plate 6.

[0024] In this specific embodiment, the inability to test products with stiff cables is effectively avoided, while also avoiding the problems of large disassembly and assembly workload, high cost, difficult maintenance, and inconvenient product loading and unloading. Specifically, when the door 4 opens and closes, the cold plate 6 moves synchronously with the door 4. The stiff cable can be led out from the test hole of the door 4, avoiding cable bending or breakage, and adapting to the testing requirements of stiff cables. The fixed frame 1, movable frame 8, vacuum tank and oil bath unit 2 form an integrated structure. The equipment does not need to be disassembled at the factory and can be used with only external water, electricity and gas. This solves the problems of cumbersome disassembly and assembly and high labor costs of existing split equipment. The cold plate 6 cooperates with the second track 16 through guide support wheels, and the movable frame 8 cooperates with the first track 5 through walking wheels. The dual track guidance ensures that the door 4 and the cold plate 6 move synchronously and smoothly, avoiding jamming or structural interference and improving the stability of the testing process.

[0025] Furthermore, the front end of the fixed frame 1 extends horizontally to form a rigid mounting platform. A vacuum tank 3 is mounted on top of the platform. A first track 5 is fixedly installed on the upper surface of the mounting platform, near the vacuum tank, to guide the sliding of the movable frame 8. The vacuum tank includes a tank body 3 and a door 4. The tank body 3 is a hollow, barrel-shaped structure with an open front end, horizontally fixed to the mounting platform. A second track 16 is provided on the bottom surface of the tank body 3, parallel to the opening direction. The door 4 is a circular / square sealing plate that matches the front opening of the tank body 3, used to achieve a vacuum seal. The cold plate 6 is a horizontally positioned metal plate, one side of which is rigidly fixed to the inner wall of the door 4 by bolts. Guide support wheels are symmetrically welded to the lower surface of the cold plate 6. These guide support wheels slide in conjunction with the second track 16 inside the tank body 3, guiding the cold plate 6 to move synchronously with the door 4. Four wheels are installed at the four corners of the bottom of the movable frame 8, slidingly connected to the first track 5 of the mounting platform of the fixed frame 1 via the wheels. The outer wall of the movable frame 8 is fixedly connected to the outer wall of the door 4 by bolts. The oil bath unit 2 is a heat source or cold source supply component of the thermal vacuum system. It is connected to the cold plate 6 through pipelines and is used to deliver heat transfer oil to the cold plate 6 to realize the temperature control of the test product.

[0026] In one specific embodiment, a cold plate mounting bracket is also included. The cold plate mounting bracket has a plate-shaped hollow structure. The lower side is provided with a guide support wheel that is slidably connected to the second track 16, and the upper side is provided with a cold plate 6. The cold plate mounting bracket supports the cold plate 6, prevents the cold plate 6 from being damaged when it slides relative to the second track 16, and provides support for the cold plate 6.

[0027] In one specific embodiment, the movable frame 8 has a hollow structure, with a platform 158 at the top and a fixing frame 14 above the platform 158. The fixing frame 14 is perpendicular to the surface of the platform 158 and has an "H" shaped structure. The bottom of the fixing frame 14 is fixedly connected to the platform 158, and the side wall is fixedly connected to the door 4.

[0028] In this specific embodiment, the symmetrical structure of the H-shaped fixing frame 14 ensures that the connection between the door 4 and the movable frame 8 is subjected to uniform force, while the top platform 158 of the movable frame 8 can temporarily place testing tools, reducing the time for personnel to go back and forth to retrieve parts, and can also serve as an auxiliary support when loading and unloading products, thereby improving operational efficiency.

[0029] In one specific embodiment, the sliding direction of the first track 5 and the second track 16 is the same as the opening direction of the tank body 3.

[0030] In this specific embodiment, the sliding direction of the first track 5 and the second track 16 is consistent with the opening direction of the tank body 3, ensuring that when the door 4 is opened or closed, the cold plate 6 moves along the axis of the tank body 3 without colliding with the inner wall or heat sink of the tank body 3. The first track 5 and the second track 16 are aligned, so only the parallelism of one track needs to be calibrated during installation to ensure overall synchronization, reducing the workload and difficulty of installation and debugging.

[0031] In one specific embodiment, there are two first tracks 5, which are arranged in parallel. There are four walking wheels, which are symmetrically arranged at the four corners of the bottom of the movable frame 8. The two parallel first tracks 5 and the four corner walking wheels form a "four-point support" structure to avoid tilting caused by uneven force when the movable frame 8 slides.

[0032] In one specific embodiment, the oil bath unit 2 is embedded at the tail end of the fixed frame 1, avoiding the space occupied by existing horizontal units under the tank, reducing the overall footprint of the equipment, and making it suitable for use in small spaces such as laboratories. Specifically, the tail end of the fixed frame 1 has a pre-reserved mounting cavity that matches the size of the oil bath unit 2. After the oil bath unit 2 is embedded in the mounting cavity, its outer side wall is flush with the side wall of the fixed frame 1, and the unit is fixed to the fixed frame 1 by bolts.

[0033] In one specific embodiment, it further includes: a cold plate oil bath pipeline 12, the cold plate 6 is connected and communicated with the oil bath unit 2 through the cold plate oil bath pipeline 12, a drag chain 7 is provided on the outside of the cold plate oil bath pipeline 12, and the cold plate oil bath pipeline 12 is a flexible hose.

[0034] In this specific embodiment, the drag chain 7 can effectively prevent the pipeline from rubbing or getting tangled with other components when it moves with the movable frame 8, and the cold plate bath oil pipeline 12 is adapted to the movement of the movable frame 8 to avoid the sealing failure of the rigid pipeline due to bending.

[0035] In one specific embodiment, one end of the cable chain 7 is fixed to the movable frame 8, and the other end is fixed to the fixed frame 1, with the cold plate bath oil pipeline 12 embedded inside the cable chain 7.

[0036] In this specific embodiment, the cable chain 7 is fixed at both ends to the movable frame 8 and the fixed frame 1, ensuring that the cable chain 7 extends and retracts synchronously as the movable frame 8 moves, preventing the cable chain 7 from jamming or falling off. The pipeline is completely embedded within the cable chain 7, avoiding the pipeline occupying extra space, reducing the risk of interference with other components, and improving the compactness of the internal structure of the equipment. In addition, the embedded design avoids accidental contact or burns caused by exposed pipelines, improving operational safety. Specifically, the cold plate bath oil pipeline 12 is completely embedded in the internal cavity of the cable chain 7. Each segment of the cable chain 7 can rotate flexibly, ensuring that the cable chain 7 extends and retracts synchronously when the movable frame 8 moves, and the pipeline is always within the protection range of the cable chain 7, without interfering with other components.

[0037] In one specific embodiment, it also includes: a heat sink and a heat sink bath oil pipeline 13, the heat sink being disposed inside the tank body 3, and the heat sink being connected to the bath oil unit 2 through the heat sink bath oil pipeline 13.

[0038] In one specific embodiment, the plate surface of the door body 4 is provided with test holes, which are suitable for leading out rigid test wires 10.

[0039] In one specific embodiment, it further includes: a connecting fixing plate 17, one end of which is rotatably disposed on the side wall of the first track, and the other end of which is provided with a buckle. When the door 4 and the tank 3 are closed, the connecting fixing plate 17 is buckled to the movable frame 8.

[0040] In this specific embodiment, the function of the connecting fixing plate 17 is to fix the movable frame 8 and the first track 5 in the vertical direction, so as to prevent displacement in the vertical direction during transportation.

[0041] In one specific embodiment, limit blocks 11 are provided at both ends of the first track 5.

[0042] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
