Description
Technical Field
[0001] The invention relates to a buffer structure and a working method for an immersion type server slide rail, and belongs to the field of server slide rails. Background Art
[0002] Due to the increasing use of content streaming, cloud computing, and industrial automation, the demand for data has never been greater. This increase in data means higher energy usage and the need to efficiently address heat issues. Immersion cooling solutions can easily accommodate the increasing heat loads of the latest processors while achieving ultra-low power consumption, thereby fulfilling energy conservation and sustainability goals. The global data center liquid cooling market is estimated to reach $6 billion by 2026. This rapid market growth is expected to be driven by the growing demand for green and energy-efficient alternatives. Immersed servers help conserve valuable data center floor space and simplify deployment without sacrificing reliability, availability, or maintainability. As a key accessory, immersible server rails are expected to continue to grow in demand. Unlike traditional air-cooled server rails, liquid-cooled servers are often mounted vertically on the ground. In this scenario, the server can easily impact the mounting point due to operator error after installation, causing internal and external damage. Summary of the Invention

[0019] Step 1: When the server slide rail opens, the first movable rail moves outward on the fixed rail via the ball bearings on the sliding frame. The elastic member loses pressure, pushing the guide post and the buffer block outward. The server coolant enters the buffer cavity through the small hole at the rear of the buffer box and fills the cavity. When the buffer block hits the first limit stop, the second movable rail also moves outward on the first movable rail via the ball bearings on the sliding frame, thus completing the slide rail opening.
[0020] Step 2. When the server slide rail is closed, the second movable rail is pushed inward, and the second movable rail moves outward on the first movable rail through the ball bearings on the sliding frame. When the second movable rail returns to its position, the first movable rail moves inward on the fixed rail through the ball bearings on the sliding frame. When the tail of the first movable rail moves to the buffer block and contacts it, it continues to move inward. The inward thrust compresses the buffer block, guide column and elastic part, and the guide column pushes the server coolant in the buffer cavity to flow out from the small hole, thereby forming a buffer.
[0021] Beneficial effect: The present invention relates to a buffer structure and working method for an immersion server slide rail, belonging to the field of server slide rails. The present invention is composed of a fixed rail, a first movable rail and a second movable rail; a buffer mechanism is provided at the end of the fixed rail, and the buffer mechanism is composed of a buffer box, a buffer cavity is provided at the head of the buffer box, a small hole is provided at the tail of the buffer box, the small hole is connected to the buffer cavity, and a guide column and an elastic member and a buffer block are arranged in the buffer cavity. When the slide rail is opened, the elastic member has no compression force, pushing the guide column and the buffer block to move outward, and the server cools down. The coolant enters the buffer cavity through the small hole at the rear of the buffer box and fills the cavity, and the buffer block stops moving when it abuts the first limit block. When the slide rail is closed, the rear end of the first movable rail abuts the buffer block to generate an inward thrust, pushing the buffer block and the guide column to move inward, and the guide column squeezes the elastic part and the coolant in the buffer cavity, thereby forming a buffer. Therefore, the present invention has a compact and reasonable structure, is easy to operate, and realizes automatic buffering, so that during operation, it can prevent collision damage caused by excessive impact, thereby reducing accidental damage to the server due to poor operation and increasing the service life of the server.

[0042] In one embodiment, a sliding frame 12 is provided on the inner side of the fixed rail 1 and the inner side of the first movable rail 2, and a ball 13 is provided on the sliding frame 12. The ball 13 of the sliding frame 12 on the fixed rail 1 is simultaneously connected to the slide groove of the fixed rail 1 and the slide groove surface of the first movable rail 2, and the ball 13 of the sliding frame 12 on the first movable rail 2 is simultaneously connected to the slide groove of the first movable rail 2 and the slide groove surface of the second movable rail 8.
[0043] In one embodiment, the head of the fixed rail 1 and the head of the first movable rail 2 are both provided with a stopper 14 , which contacts the head of the sliding frame 12 .

[0051] A method for operating a buffer structure for an immersion server slide rail includes two methods: slide rail opening buffering and slide rail closing buffering. The specific steps are as follows:
[0052] Step 1: When the server slide rail opens, the first movable rail 2 moves outward on the fixed rail 1 via the ball bearings 13 on the sliding frame 12. The elastic member 9 loses pressure, pushing the guide post 7 and the buffer block 11 outward. The server coolant enters the buffer chamber 5 through the small hole 6 at the rear of the buffer tank 4 and fills the chamber. When the buffer block 11 abuts against the first limit stop 17, the second movable rail 8 also moves outward on the first movable rail 2 via the ball bearings 13 on the sliding frame 12, thereby completing the slide rail opening operation.
[0053] Step 2. When the server slide rail is closed, the second movable rail 8 is pushed inward, and the second movable rail 8 moves outward on the first movable rail 2 through the ball 13 on the sliding frame 12. When the second movable rail 8 returns to its position, the first movable rail 2 moves inward on the fixed rail 1 through the ball 13 on the sliding frame 12. When the tail of the first movable rail 2 moves to the buffer block 11 and contacts it, it continues to move inward. The inward thrust pushes the buffer block 11, the guide column 7 and the elastic member 9 to compress, and the guide column 7 pushes the server coolant in the buffer chamber 5 to flow out from the small hole 6, thereby forming a buffer.
[0054] Working principle: When the present invention is working, first, when the slide rail is opened, the first movable rail 2 and the second movable rail 8 move outward in sequence, and then the first movable rail 2 moves the sliding frame 12 in the fixed rail 1 through the ball 13, and the second movable rail 8 moves the sliding frame 12 in the first movable rail 2 through the ball 13. At the same time, the buffer mechanism 3 also works, the elastic member 9 loses pressure, and pushes the guide column 7 and the buffer block 11 to move outward. The server coolant enters the buffer cavity 5 through the small hole 6 at the tail of the buffer box 4 and fills the cavity. When the buffer block 11 presses against the first limit block 17, the second movable rail 8 also moves outward on the first movable rail 2 through the ball 13 on the sliding frame 12, thereby completing the opening of the slide rail;
[0055] When the slide rail is closed, the first movable rail 2 and the second movable rail 8 move inward in turn, and then the first movable rail 2 moves the sliding frame 12 in the fixed rail 1 through the ball 13, and the second movable rail 8 moves the sliding frame 12 in the first movable rail 2 through the ball 13. When the second limit block 18 at the head of the second movable rail 8 contacts the stop portion 14 of the first movable rail 2, the second movable rail 8 returns to its original position; at this time, the first movable rail 2 moves inward on the fixed rail 1 through the ball 13 on the sliding frame 12, and when the tail of the first movable rail 2 moves to the buffer block 11 and contacts it, it continues to move inward, and the inward thrust pushes the buffer block 11, the guide column 7 and the elastic member 9 to compress, and the guide column 7 pushes the server coolant in the buffer chamber 5 to flow out from the small hole 6, thereby forming a buffer, and when the second limit block 18 at the head of the first movable rail 2 contacts the stop portion 14 of the fixed rail 1, the first movable rail 2 returns to its original position.
[0056] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the scope of protection of the present invention.
