Description

Technical Field

[0001] This utility model belongs to the field of server technology, specifically a server rear window ventilation component. Background Technology

[0002] Servers provide computing or application services to other clients (such as PCs, smartphones, ATMs, and other terminal devices) on a network. Servers have high-speed CPU computing power, powerful I / O external data throughput capabilities, better scalability, and long reliable operating time.

[0003] In current common server designs, an intake fan is typically installed at the front of the chassis. This fan draws in cool external air through negative pressure. The cool air then flows past internal heat-generating components, heating up and becoming hot air before being exhausted from the rear of the chassis. However, the dense layout of internal components and complex airflow paths in servers result in significant overall air resistance. This causes the kinetic energy of the cool air to gradually decrease as it passes through the chassis, reducing exhaust efficiency. This can easily lead to airflow stagnation in the rear area, causing heat buildup, creating localized hotspots, affecting system stability, and potentially shortening the lifespan of components. Utility Model Content

[0004] The purpose of this invention is to provide a server rear window ventilation component to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A server rear window ventilation assembly includes a rear window body and a cooling fan. The rear window body has symmetrically arranged fixing plates on both sides. An extension plate is provided on the opposite side of each of the two fixing plates. Threaded rods are rotatably connected to each of the two extension plates. Handles are provided at the top ends of the two threaded rods, and lifting plates are threadedly connected to the bottom ends of the two threaded rods. Slide grooves are provided on the opposite sides of the two lifting plates and the two fixing plates. Two sliders slide within each of the four slide grooves. Slide rods are threadedly connected between two corresponding left and right sliders. At least two locking blocks are slidably connected to each slide rod. Connecting holes are provided at the four corners of both ends of the cooling fan. Locking holes aligned with the connecting holes are provided on several locking blocks, and the locking holes are fixedly connected to the connecting holes by bolts.

[0007] Furthermore, the lock block is provided with a positioning threaded hole, which is set perpendicular to the axis of the slide rod, and a positioning screw is threaded onto the positioning threaded hole.

[0008] Furthermore, two guide rods are fixedly installed at the bottom of the two extension plates respectively. The two guide rods are symmetrically arranged on both sides of the corresponding threaded rod. The two lifting plates are respectively provided with guide holes for the two guide rods to pass through.

[0009] Furthermore, the tops of several fixed plates and lifting plates are respectively provided with limiting holes, and the tops of several sliders are respectively threaded with limiting rods that slide in cooperation with the limiting holes.

[0010] Furthermore, each of the limiting rods has an outward protrusion above the limiting hole, and a rubber sleeve is fitted between the outward protrusion and the limiting hole, the size of which is larger than the size of the limiting hole.

[0011] Furthermore, each of the two extension plates has a downwardly extending support plate at the end away from the fixed plate, and each of the two support plates has an upwardly extending T-shaped groove at the bottom. The opening of the T-shaped groove faces the lifting plate side, and the lifting plate side has a T-shaped limiting part that slides with the T-shaped groove.

[0012] The beneficial effects of this utility model are:

[0013] This invention allows for three-way adjustment to accommodate the height, width, and thickness of the cooling fan to be installed. In the height direction, manually rotating the handles on both sides drives the threaded rods, causing the lifting plates to rise and fall vertically through threaded transmission. Adjusting the height of the two sets of lifting plates changes the distance between the upper and lower sliding rods, thus accommodating cooling fans of different heights. In the thickness direction, the front and rear sliders slide within grooves on the fixed and lifting plates. Adjusting the position of the sliders within the grooves changes the distance between the front and rear sliding rods, accommodating cooling fans of different thicknesses. In the width direction, each sliding rod... All the locking blocks on the rod can slide freely along the rod body. Adjust the distance between the locking blocks on the left and right sides according to the width of the cooling fan, so that they are aligned with the connection holes on the four corners of the fan. After completing the three-way adjustment, place the cooling fan between the front and rear sliding rods, so that the connection holes on the four corners of the fan correspond one by one with the locking holes on each locking block. Then, use bolts to pass through the locking holes of the locking blocks and the connection holes of the fan in sequence, and tighten them with nuts, thereby fixing the cooling fan on the support frame composed of sliding rods and locking blocks. When the internal temperature of the server casing rises during operation, the cooling fan can be activated to quickly exhaust the hot air accumulated inside through the rear window body, improving the heat dissipation efficiency.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please refer to Figure 1-3 ;

[0021] A server rear window ventilation assembly includes a rear window body 1 fixedly connected to the server housing (not shown) and a cooling fan 2. The rear window body 1 has symmetrically arranged rearward-extending fixed plates 3 on both sides. Each of the two fixed plates 3 has an extension plate 4 on its opposite side. Threaded rods 31 are rotatably connected to each of the two extension plates 4. Handles 311 for manual rotation of the threaded rods 31 are fixedly installed at the top of each threaded rod 31. Lifting plates 32 are threadedly connected to the bottom of each threaded rod 31. Rotating the handles 311 rotates the threaded rods 31, allowing the lifting plates 32 to move up and down. Slide grooves 33 are provided on the opposite sides of the two lifting plates 32 and the two fixed plates 3. Two sliders 34 slide within each of the four slide grooves 33. A sliding rod 35 is provided between two corresponding sliders 34. The two ends of the sliding rod 35 are threadedly connected to the corresponding sliders 34, ensuring a stable connection between the sliding rod 35 and the two sliders 34. At least two locking blocks 36 are slidably connected to each slide rod 35. The locking blocks 36 can slide along the slide rod 35 to adjust the spacing between them. Connecting holes 21 are provided at the four corners of the front and rear ends of the cooling fan 2. Each locking block 36 has a locking hole 361 that matches the corresponding connecting hole 21 on the cooling fan 2. When the locking block 36 moves to the position where the locking hole 361 aligns with the connecting hole 21, bolts 364 can be used to pass through the locking hole 361 and the connecting hole 21 in sequence and tighten them to connect the cooling fan 2 to each locking block 36. This fixes the cooling fan 2 behind the rear window body 1. When the internal temperature of the server casing rises during operation, activating the cooling fan 2 can quickly expel the accumulated hot air from the rear window body 1, improving heat dissipation efficiency. It should be noted that the number of cooling fans 2 can be increased by increasing the number of locking blocks 36 on each slide rod 35, thereby improving the heat dissipation effect.

[0022] Specifically, based on the dimensions of the cooling fan 2 to be installed, three-way adjustments are made to adapt to its height, width, and thickness. In the height direction, by manually rotating the handles 311 on both sides, the threaded rod 31 is driven to rotate, and the lifting plate 32 achieves vertical lifting under the action of threaded transmission. By adjusting the height of the two sets of lifting plates 32, the distance between the upper and lower sliding rods 35 can be changed, thereby adapting to cooling fans 2 of different heights. In the thickness direction, the front and rear sliders 34 can slide within the grooves 33 on the fixed plate 3 and the lifting plate 32. By adjusting the front and rear positions of the sliders 34 in the grooves 33, the distance between the front and rear sliding rods 35 can be changed, thereby adapting to cooling fans 2 of different thicknesses. In the width direction, each sliding rod 35 has a lock. All blocks 36 can slide freely along the rod. Adjust the distance between the left and right locking blocks 36 according to the width of the cooling fan 2, so that they are aligned with the connection holes 21 on the four corners of the fan. After completing the three-way adjustment, place the cooling fan 2 between the front and rear sliding rods 35, so that the connection holes 21 on the four corners of the fan correspond one-to-one with the locking holes 361 on each locking block 36. Then, use bolts 364 to pass through the locking holes 361 of the locking blocks 36 and the connection holes 21 of the fan in sequence, and tighten them with nuts, thereby fixing the cooling fan 2 on the support frame composed of the sliding rods 35 and locking blocks 36. When the internal temperature of the server casing rises during operation, the cooling fan 2 can be activated to quickly exhaust the hot air accumulated inside from the rear window body 1, thereby improving the heat dissipation efficiency.

[0023] In this embodiment, the locking block 36 is provided with a positioning threaded hole 362, which is perpendicular to the axis of the slide rod 35. A positioning screw 363 is threaded onto the positioning threaded hole 362. After the cooling fan 2 is installed, the positioning screw 363 is screwed into the positioning threaded hole 362 of the locking block 36. As the positioning screw 363 is tightened, its end gradually approaches and finally comes into close contact with the surface of the slide rod 35, thereby generating sufficient friction to prevent the locking block 36 from sliding on the slide rod 35. The positioning screw 363 axially locks the locking block 36, fixing the relative position of the locking block 36 on the slide rod 35. This avoids displacement of the locking block 36 due to vibration or mechanical shaking during operation, thereby ensuring the stability of the cooling fan 2 during operation.

[0024] In this embodiment, two guide rods 37 are fixedly installed at the bottom of the two extension plates 4 respectively. The two guide rods 37 are symmetrically arranged on both sides of the corresponding threaded rods 31. The two lifting plates 32 are respectively provided with guide holes for the two guide rods 37 to pass through. Through the cooperation of the guide rods 37 and the guide holes 322, the lifting plate 32 is guided to move up and down. When the rotating handle 311 drives the threaded rod 31 to rotate, the lifting plate 32 moves up and down axially under the action of thread transmission. The guide rods 37 on both sides restrict the rotation tendency of the lifting plate 32, prevent it from rotating with the threaded rod 31, and ensure that the lifting process is smooth and without deviation.

[0025] In this embodiment, the tops of several fixed plates 3 and lifting plates 32 are respectively provided with limiting holes 38, and the tops of several sliders 34 are respectively threadedly connected with limiting rods 341 that slide in cooperation with the limiting holes 38. Preferably, the bottom of the limiting rod 341 is a threaded part that is threadedly connected to the slider 34, and the top of the threaded part is a smooth part that slides in cooperation with the limiting holes 38. Through the cooperation between the limiting rods 341 and the limiting holes 38, the sliding process of the sliders 34 is guided and limited. When the front and rear positions of the sliders 34 in the slide groove 33 are adjusted to accommodate cooling fans 2 of different thicknesses, the limiting rods 341 move synchronously within the limiting holes 38 to prevent the sliders 34 from deviating during the sliding process and causing them to disengage from the slide groove 33.

[0026] In this embodiment, several limiting rods 341 are provided with protrusions 342 above the limiting holes 38. A rubber sleeve 343 is fitted between the protrusions 342 and the limiting holes 38. The size of the rubber sleeve 343 is larger than the size of the limiting holes 38. When it is necessary to adjust the position of the slider 34 to accommodate cooling fans 2 of different thicknesses, the limiting rods 341 can be rotated upward to loosen them, allowing the slider 34 to slide back and forth along the slide groove 33 to the desired position. After the slider 34 is adjusted to the desired position, the limiting rods 341 are rotated downward to gradually press down the protrusions 342 until their bottom tightly presses against the rubber sleeve 343. At this time, the rubber sleeve 343 is compressed, and its lower end tightly abuts against the top surface of the lifting plate 32 or the fixed plate 3, thereby generating greater frictional resistance, fixing the slider 34 in the current position and preventing it from sliding in the slide groove 33.

[0027] In this embodiment, the ends of the two extension plates 4 away from the fixed plate 3 are respectively provided with downwardly extending support plates 41. The bottom of the two support plates 41 is respectively provided with upwardly extending T-shaped grooves 42. The openings of the T-shaped grooves 42 face the lifting plate 32. The lifting plate 32 is provided with a T-shaped limiting part 321 that slides with the T-shaped groove 42. Through the sliding cooperation between the T-shaped limiting part 321 and the T-shaped groove 42, auxiliary guidance and lateral limiting functions are provided for the vertical movement of the lifting plate 32. When the rotating handle 311 drives the threaded rod 31 to rotate, driving the lifting plate 32 to rise and fall in the vertical direction, the T-shaped limiting part 321 slides synchronously in the T-shaped groove 42, limiting the displacement of the lifting plate 32 in the lateral and front-back directions, preventing it from swaying during movement, and further improving the rigidity and operational stability of the lifting mechanism.
