Description

Technical Field

[0001] This utility model relates to a data management device, specifically a data management device with a heat dissipation structure and modular storage management, belonging to the field of data equipment technology. Background Technology

[0002] With the rapid development of data management systems, the density of data management system hardware, namely data center servers and storage devices, is constantly increasing, which puts forward higher requirements for the heat dissipation, storage scalability, maintenance convenience and stability of data management devices.

[0003] Traditional data management devices often face the following problems in high-density computing environments: First, hard drive installation and maintenance are inconvenient. Replacing a hard drive in a traditional rack usually requires shutting down the system and disassembling multiple components, which is complicated and increases the risk of system downtime. Second, the heat dissipation structure is unreasonable. Especially when the equipment is running at full load, hot spots can easily form inside the rack, causing the equipment to overheat and affecting system stability and equipment lifespan.

[0004] Therefore, there is an urgent need for a data management device with an optimized heat dissipation structure and a convenient modular storage management solution to meet the demands of modern data centers for high performance, high reliability, and high efficiency. Utility Model Content

[0005] Based on the above background, the purpose of this utility model is to provide a data management device that solves the problems of unreasonable heat dissipation structure and inconvenient hard drive installation and maintenance mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A data management device includes an outer cabinet and an inner cabinet. The outer cabinet has an openable and closable front door, an exhaust fan assembly on its top, and intake fans on its lower sides. The inner cabinet is embedded inside the outer cabinet and has a frame structure. The inner cabinet is fixedly connected to the outer cabinet. Multiple drawer-type hard drive trays are located on the front of the inner cabinet facing the front door. Each drawer-type hard drive tray is individually slidably connected to the inner cabinet. The drawer-type hard drive trays are linearly arranged from the top to the bottom of the inner cabinet. The bottom of the inner cabinet is an open structure and is connected to the intake fans. The top of the inner cabinet is connected to the exhaust fan assembly. Each drawer-type hard drive tray has a shock-absorbing foam pad inside, and the surface of the shock-absorbing foam pad has multiple ventilation holes arranged in an array. Guide rails are located on both sides of each drawer-type hard drive tray, and the drawer-type hard drive tray is slidably connected to the inner cabinet via these guide rails.

[0008] Preferably, the outer cabinet also includes a front frame, a top plate, a bottom plate, a left side plate, a right side plate, and a rear plate. The front door is hinged to the front frame, the exhaust fan assembly is fixed to the top plate, and the intake fans are respectively fixed to the lower parts of the left side plate and the lower parts of the right side plate.

[0009] Preferably, the intake fan is surrounded by an auxiliary air intake hole array, which includes multiple circular holes with a diameter of 6-30 mm, arranged around the central axis of the intake fan. The auxiliary air intake holes around the intake fan can form secondary airflow channels, reducing airflow bottlenecks and dead zones. Furthermore, since the intake fan generates a certain pressure difference during operation, the auxiliary air intake holes around the fan can partially balance this pressure difference, reducing overall wind resistance and enabling the intake fan to generate a greater effective airflow with the same power consumption.

[0010] Preferably, the circular holes in the auxiliary air intake array have a gradually varying density distribution, with the diameter of the circular holes closer to the intake fan being smaller than that of the circular holes farther from the intake fan, and the density of the circular holes closer to the intake fan being greater than that of the circular holes farther from the intake fan. This arrangement of the auxiliary air intake array has a certain airflow guiding effect, reducing the generation of eddies.

[0011] Preferably, the exhaust fan assembly includes a main exhaust fan and at least four auxiliary exhaust fans. The main exhaust fan is located in the middle area of ​​the top of the outer cabinet, and the auxiliary exhaust fans are located in the outer peripheral area of ​​the top of the outer cabinet. The auxiliary exhaust fans are symmetrically arranged with the main exhaust fan as the center.

[0012] Preferably, the shock-absorbing foam pad is made of polyurethane material, the thickness of the shock-absorbing foam pad is 8-12mm, the cross-section of the vent hole is rectangular, the width of the vent hole is 3-5mm, and the spacing between the vent holes is 10-15mm.

[0013] Preferably, the drawer-type hard disk tray is provided with elastic clamping members on both sides inside, and the elastic clamping members have an arc-shaped spring structure.

[0014] Preferably, the inner cabinet also includes a motherboard compartment and a power supply compartment, both of which are located on the side of multiple drawer-type hard drive trays, with the motherboard compartment located above the power supply compartment.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This utility model discloses a data management device that achieves efficient heat dissipation through an inner and outer dual-cabinet structure and optimized airflow path design. The intake fans on both sides of the outer cabinet and the exhaust fan assembly on the top form a three-dimensional heat dissipation path of "bottom in, top out." The raised bottom design of the inner cabinet allows cool air to be evenly distributed before flowing through the hard drive area. The linear arrangement of the drawer-type hard drive trays along the airflow direction ensures that all hard drives are cooled. The array of vents on the shock-absorbing foam pads improves heat dissipation efficiency while maintaining shock absorption. This utility model uses independent drawer-type hard drive trays, allowing maintenance personnel to quickly and conveniently replace hard drives without disassembling other parts of the cabinet. This utility model solves the technical problems of uneven heat dissipation and inconvenient hard drive maintenance in traditional data management devices through structural optimization.

In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0025] like Figure 1 As shown, an embodiment of this utility model discloses a data management device, including an outer cabinet 1 and an inner cabinet 2.

[0026] The outer cabinet 1 is equipped with a front door 101 that can be opened and closed, an exhaust fan assembly is provided on the top of the outer cabinet 1, and air intake fans 104 are provided on the lower sides of the outer cabinet 1 respectively.

[0027] The inner cabinet 2 is embedded inside the outer cabinet 1. The inner cabinet 2 has a frame structure and is fixedly connected to the outer cabinet 1. The front of the inner cabinet 2 facing the front door 101 is provided with multiple drawer-type hard disk trays 201. Each drawer-type hard disk tray 201 is individually slidably connected to the inner cabinet 2. The drawer-type hard disk trays 201 are arranged linearly from the top to the bottom of the inner cabinet 2. The bottom of the inner cabinet 2 is an open structure and is connected to the intake fan 104. The top of the inner cabinet 2 is connected to the exhaust fan assembly.

[0028] like Figure 2 As shown, the drawer-type hard drive tray 201 has a shock-absorbing foam pad 202 inside. The surface of the shock-absorbing foam pad 202 has multiple ventilation holes 203 arranged in an array. The drawer-type hard drive tray 201 has guide rails 204 on both sides. The drawer-type hard drive tray 201 is slidably connected to the inner cabinet 2 through the guide rails 204.

[0029] Specifically, the outer cabinet 1 also includes a front frame 105, a top plate 106, a bottom plate 107, a left side plate 108, a right side plate 109, and a rear plate 110. The front door 101 is hinged to the front frame 105. The exhaust fan assembly is fixed to the top plate 106, and the intake fan 104 is fixed to the lower part of the left side plate 108 and the lower part of the right side plate 109, respectively.

[0030] Specifically, an auxiliary air intake array 111 is provided around the intake fan 104. The auxiliary air intake array 111 includes multiple circular holes with a diameter of 6-30mm, and surrounds the intake fan 104 with the central axis as the center. The auxiliary air intake holes around the intake fan 104 can form a secondary airflow channel, reducing airflow bottlenecks and dead zones. Furthermore, the intake fan 104 generates a certain pressure difference during operation, and the auxiliary air intake holes around the intake fan 104 can partially balance this pressure difference, reduce overall wind resistance, and enable the intake fan 104 to generate a greater effective airflow under the same power consumption.

[0031] Specifically, the circular holes in the auxiliary air intake array 111 have a gradually varying density distribution. The diameter of the circular holes closer to the intake fan 104 is smaller than that of the circular holes farther away from the intake fan 104, and the density of the circular holes closer to the intake fan 104 is greater than that of the circular holes farther away from the intake fan 104. This arrangement of the auxiliary air intake array 111 has a certain airflow guiding effect, reducing turbulence generation.

[0032] Specifically, the exhaust fan assembly includes a main exhaust fan 102 and at least four auxiliary exhaust fans 103. The main exhaust fan 102 is located in the middle area of ​​the top of the outer cabinet 1, and the auxiliary exhaust fans 103 are located in the outer peripheral area of ​​the top of the outer cabinet 1. The auxiliary exhaust fans 103 are symmetrically arranged with the main exhaust fan 102 as the center.

[0033] Specifically, the shock-absorbing foam pad 202 is made of polyurethane material, the thickness of the shock-absorbing foam pad 202 is 8-12mm, the cross-section of the vent 203 is rectangular, the width of the vent 203 is 3-5mm, and the spacing between the vent 203 is 10-15mm.

[0034] Specifically, the drawer-type hard drive tray 201 is also provided with elastic clamping members 205 on both sides inside. The elastic clamping members 205 have an arc-shaped spring structure and are used to limit the hard drive.

[0035] Specifically, such as Figure 3 As shown, the inner cabinet 2 also has a motherboard compartment 206 and a power supply compartment 207. Both the motherboard compartment 206 and the power supply compartment 207 are located on the side of multiple drawer-type hard drive trays 201, with the motherboard compartment 206 located above the power supply compartment 207.

[0036] In addition, the inner cabinet 2 is provided with a back panel assembly at the rear of the multiple drawer-type hard drive trays 201. The back panel assembly integrates a multi-channel data transmission interface and a power distribution terminal for electrically connecting the hard drives loaded in the drawer-type hard drive trays 201.

[0037] This data management device features a three-dimensional heat dissipation path with air intake from the bottom on both sides and exhaust from the top, forming a complete bottom-in, top-out airflow circulation system. The inner cabinet 2 and outer cabinet 1 form a double-layer structure. The inner cabinet 2 has a frame structure with an open bottom, allowing cool air to first enter the space between the outer cabinet 1 and the inner cabinet 2, and then enter the interior of the inner cabinet 2 through the open bottom. Drawer-type hard drive trays 201 are arranged linearly from the top to the bottom of the inner cabinet 2, following the bottom-in, top-out airflow direction to ensure each hard drive is adequately cooled. The surface of the shock-absorbing foam pad 202 inside the drawer-type hard drive tray 201 is designed with multiple arrayed ventilation holes 203. This microporous array structure allows airflow to directly contact the hard drive surface, while the foam material provides thermal insulation and cushioning, achieving both heat dissipation and shock absorption.

[0038] Each drawer-type hard drive tray 201 can be pulled out and pushed in individually, without affecting the normal operation of other hard drives when replacing one. The outer cabinet 1 is equipped with a front door 101 that can be opened and closed. Combined with the design of the drawer-type hard drive trays 201 facing the front door 101, maintenance personnel can directly access and operate the hard drives from the front without disassembling the cabinet side panels or touching other components inside the cabinet.

[0039] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
