Description

Technical Field

[0001] This utility model relates to the field of server heat dissipation, specifically to a backplate heat exchange assembly. Background Technology

[0002] The backplane heat exchange assembly is installed at the rear door of the server rack, directly cooling the high-temperature air coming out of the server. It features the shortest supply and return air distance and high return air temperature, thus achieving a high energy efficiency ratio and reducing the total power consumption of the data center. However, since the backplane is installed at the rear door of the server rack, maintenance of the server rack requires frequent opening and closing of the door, which places strict requirements on the external installation of the backplane piping and the opening and closing angle of the backplane.

[0003] Chinese utility model patent CN222692162U discloses a back panel air conditioner, an integrated cabinet, and an air conditioning system. The system includes a back panel hinged to a cabinet for opening and closing the cabinet.

The flat mounting plate is positioned near the hinge point between the back panel and the cabinet. The inclined mounting plate slopes towards the inner side panel of the back panel. The connecting plate is connected to the inner side panel of the back panel. A heat exchange assembly is mounted on the flat mounting plate for heat dissipation inside the cabinet. An observation window is mounted on the inclined mounting plate. An observation hole is located on the inner side panel of the back panel corresponding to the observation window, allowing observation of the cabinet's interior. The heat exchange assembly includes a heat exchanger mounted on the inner side panel of the flat mounting plate, containing refrigerant and a fan. A fan is mounted on the outer side panel of the flat mounting plate to increase the airflow near the heat exchanger.

[0004] The aforementioned technologies have the following drawbacks: the heat exchanger and fan are integrated on the back plate, resulting in a heavy back plate that is difficult to open and close. Moreover, both the heat exchanger and the fan require the back plate to be opened for maintenance, making the operation cumbersome. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0030] This utility model provides a backplate heat exchange assembly, the structure of which is as follows: Figure 1 - Figure 4 As shown, it includes an external door 1, a heat exchanger 2, an internal door 3, and a fan 4.

[0031] The external door 1 is rotatably connected to the cabinet, and the external door 1 has a connection end for connecting to external equipment.

[0032] The heat exchanger 2 is installed on the outer door 1.

[0033] The embedded door 3 is rotatably connected to the outer door 1 on the side away from the connection end.

[0034] The fan 4 is installed on the embedded door 3, with the air inlet of the fan 4 facing the heat exchanger 2 and the air outlet of the fan 4 facing outward.

[0035] During operation, fan 4 drives airflow, and hot air flows out of the cabinet, passing through heat exchanger 2 mounted on the external door 1. The refrigerant or coolant inside heat exchanger 2 exchanges heat with the hot air, absorbing heat and cooling the air. The cooled air then returns to the cabinet, completing the air circulation and heat exchange. External door 1 and internal door 3 serve as support and mounting carriers, while also ensuring a rational airflow layout, allowing air to flow smoothly through heat exchanger 2 for efficient heat dissipation.

[0036] In this invention, the heat exchanger 2 and the fan 4 are respectively installed on the external door 1 and the internal door 3, which distributes the weight. During maintenance, it is only necessary to open the external door 1 to inspect the heat exchanger 2 and open the internal door 3 to inspect the fan 4, which reduces the labor intensity of the operators and improves the maintenance efficiency.

[0037] To provide an installation base for external door 1, please refer to... Figure 1 In a preferred embodiment, the heat exchange assembly further includes an outer frame 5, which is connected to the cabinet, and the external door 1 is rotatably connected to the outer frame 5.

[0038] During use, the outer frame 5 is connected to the cabinet, providing a stable foundation support structure for the entire heat exchange assembly. At the same time, the outer frame 5 also extends the length of the cabinet, ensuring that the installation and layout of the heat exchange assembly do not affect the internal structure of the cabinet.

[0039] To improve the smoothness of the appearance, please refer to... Figure 1 In a preferred embodiment, when the external door 1 is closed, the external door 1 is embedded in the outer frame 5.

[0040] When in use, the outer door 1, after being embedded in the outer frame 5, has a smoother and more aesthetically pleasing appearance, enhancing the overall visual effect of the equipment. At the same time, the outer frame 5 protects the edges of the outer door 1, preventing damage from collisions and scratches, and extending the service life of the outer door 1.

[0041] To further improve the smoothness of the appearance, please refer to... Figure 1 In a preferred embodiment, when the embedded door 3 is closed, the embedded door 3 is embedded inside the outer door 1.

[0042] When in use, the recessed door 3, after being embedded into the outer door 1, has a smoother and more aesthetically pleasing appearance, enhancing the overall visual effect of the equipment. At the same time, the outer door 1 protects the edges of the recessed door 3, preventing damage from collisions and scratches, and extending the service life of the recessed door 3.

[0043] To achieve heat exchange between the hot air and coolant inside the cabinet, please refer to... Figure 2 In a preferred embodiment, the heat exchanger 2 includes an inlet pipe 21, a drain pipe 22, a collecting pipe 23, and fins 24. The inlet pipe 21 is connected to the bottom of the outer door 1, the drain pipe 22 is connected to the top of the outer door 1, the outlet of the inlet pipe 21 is connected to the inlet of the collecting pipe 23, the outlet of the collecting pipe 23 is connected to the inlet of the drain pipe 22, and the fins 24 are connected to the collecting pipe 23.

[0044] During operation, under pressure, coolant flows into heat exchanger 2 from inlet pipe 21. After entering collector pipe 23, the coolant flows within the pipe. Hot air inside the cabinet flows towards collector pipe 23 under the action of fan 4. The air contacts the outer wall of collector pipe 23, while low-temperature coolant flows inside. Due to the temperature difference, heat is transferred from the high-temperature air to the low-temperature coolant, achieving the first heat exchange. Fins 24 are connected to collector pipe 23, greatly increasing the contact area between collector pipe 23 and air. After the heat exchange, the heated coolant flows out from the outlet of collector pipe 23 and enters the inlet of drain pipe 22.

[0045] To improve the cleanliness of the server rack, please refer to... Figure 2 In a preferred embodiment, the heat exchange assembly further includes a filter 6 and a connecting component 7, wherein the filter 6 is detachably connected to the side of the outer door 1 near the connecting end via the connecting component 7.

[0046] During operation, the clean air filtered by filter 6 continues to flow, exchanging heat with the coolant in heat exchanger 2. The cooled air then returns to the cabinet to further cool the equipment. As the air circulates continuously, filter 6 continues to perform its filtering function, ensuring that the air inside the cabinet remains relatively clean, reducing damage to the equipment from impurities and extending its service life.

[0047] To ensure accurate installation of filter 6, please refer to... Figure 3 In a preferred embodiment, the connecting assembly 7 includes a first bolt 71, the filter screen 6 has a strip hole 72, the outer door 1 has a screw hole 73, the first bolt 71 passes through and is slidably connected in the strip hole 72, and the first bolt 71 is threadedly connected in the screw hole 73.

[0048] When using the filter screen 6, first roughly align the slotted hole 72 on the filter screen 6 with the screw hole 73 on the outer door 1. Pass the first bolt 71 through the slotted hole 72. At this point, the bolt is not yet tightened, and the filter screen 6 can be finely adjusted within the length of the slotted hole 72. By rotating the first bolt 71, it gradually threads into the screw hole 73 on the outer door 1. As the bolt tightens, the bolt head gradually presses against the filter screen 6, making the filter screen 6 fit tightly against the outer door 1.

[0049] To reduce the possibility of damage to filter 6, please refer to Figure 3 In a preferred embodiment, the connecting assembly 7 further includes a gasket 74, which is fitted onto the first bolt 71 and is located between the filter screen 6 and the nut of the first bolt 71.

[0050] During use, the gasket 74 can evenly distribute the tightening force of the first bolt 71 onto the filter screen 6. This prevents the filter screen 6 from being damaged due to excessive local stress, and ensures that the filter screen 6 is subjected to uniform pressure across the entire mounting surface, thus fitting more tightly and smoothly onto the outer door 1, improving the installation stability and filtration effect of the filter screen 6.

[0051] To secure fan 4 to the recessed door 3, please refer to... Figure 4 In a preferred embodiment, the recessed door 3 further includes a fixing component 8, which includes a screw 81 that passes through the fan 4 and is threaded onto the recessed door 3.

[0052] When installing the fan 4, first align the mounting holes on the fan 4 with the corresponding holes on the recessed door 3. Then, pass the screw 81 through the mounting holes on the fan 4, align the screw 81 through the fan 4 with the threaded hole on the recessed door 3, and rotate the screw 81 to gradually screw it into the threaded hole of the recessed door 3. As the screw 81 is screwed in, the threaded engagement between the screw 81 and the threaded hole generates a tightening force, which makes the fan 4 fit tightly against the recessed door 3.

[0053] To improve the stability of fan 4 during operation, please refer to... Figure 4 In a preferred embodiment, the fan 4 is provided in multiple ways, and the embedded door 3 further includes a reinforcing component 9. The reinforcing component 9 includes a guide rail 91, a pressure plate 92, and a second bolt 93. The guide rail 91 is connected to the embedded door 3 and is located between adjacent fans 4. The pressure plate 92 is slidably connected to the guide rail 91 and has a through hole. The guide rail 91 has threaded holes spaced apart along its length. The second bolt 93 passes through the through hole and is threaded into the threaded hole so that the pressure plate 92 abuts against the fan 4.

[0054] During use, since the guide rail 91 has threaded holes spaced along its length, and the pressure plate 92 has through holes, when it is necessary to fix fans 4 of different sizes or with slight positional deviations, the operator can slide the pressure plate 92 along the guide rail 91 according to the actual position of the fan 4, so that the through holes on the pressure plate 92 are aligned with the threaded holes in the appropriate positions. This adjustable design can adapt to the installation requirements of fans 4 of various specifications. After the pressure plate 92 is adjusted to the appropriate position, the second bolt 93 is passed through the through hole on the pressure plate 92 and threaded into the corresponding threaded hole on the guide rail 91. As the bolt is tightened, the friction between the pressure plate 92 and the fan 4 increases, ultimately fixing the fan 4 firmly to the embedded door 3. This ensures that the fan 4 will not loosen and guarantees the stable operation of the fan 4.

[0055] To better understand this utility model, the following is combined with... Figure 1 - Figure 4 The working principle of a backplate heat exchange assembly according to this utility model is described in detail: Fan 4 drives airflow, and hot air flows out of the cabinet and passes through heat exchanger 2 installed on the external door 1. The refrigerant or coolant in the heat exchanger 2 exchanges heat with the hot air, absorbing heat and cooling the air. The cool air then returns to the cabinet, completing the air circulation and heat exchange. The external door 1 and the embedded door 3 serve as support and mounting carriers, while ensuring a reasonable layout of the air duct, allowing air to flow smoothly through the heat exchanger 2 and achieving efficient heat dissipation.

[0056] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
