Description

Technical Field

[0001] This utility model belongs to the field of data management technology, and more specifically, relates to a database management device. Background Technology

[0002] Databases, as the core container for storing data, possess enormous data carrying capacity, easily accommodating millions, tens of millions, or even hundreds of millions of data records. In practical applications, databases primarily rely on hard drives as the data storage medium; however, the storage capacity of a single hard drive has physical limitations. When processing massive amounts of data, a multi-hard drive collaborative storage solution must be adopted. This necessitates the deployment of a professional storage management rack system, which uses modular design to achieve centralized management and efficient storage of multiple hard drives.

[0003] However, with the increasing number of hard drives and the dense arrangement of hardware devices inside the storage management rack system, this setup generates a lot of heat during operation. Excessive temperature accelerates the wear and tear of internal mechanical components of the hard drives, reduces hard drive read and write performance, shortens hard drive lifespan, and increases the risk of data loss. Therefore, it is necessary to design a database management device to effectively solve the above-mentioned technical problems. Utility Model Content

[0004] In order to solve the problems existing in the prior art, this utility model aims to provide a database management device with good heat dissipation effect to ensure the stability of hard disk operation.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A database management device includes cabinet A and cabinet B, with each cabinet A and cabinet B having an openable door at its front end. Cabinet A has an internal mounting base for installing a hard drive, and water-cooled plates for cooling the interior of cabinet A are installed both inside cabinet A and on the inside of its respective cabinet door. The mounting base and the water-cooled plates inside cabinet A are both mounted within cabinet A via a support mechanism. Cabinet B has a cooling mechanism connected to the water-cooled plates via corresponding pipes.

[0007] Furthermore, four sets of the aforementioned support mechanisms are provided inside the cabinet A.

[0008] Furthermore, each set of the support mechanism includes a pair of support rods fixed inside the cabinet A, and multiple sets of mounting plates are arranged between the pair of support rods from top to bottom.

[0009] Furthermore, the mounting plate has through holes.

[0010] Furthermore, the through holes are elongated holes, and the through holes are evenly distributed on the mounting plate.

[0011] Furthermore, the water-cooled plate, located inside the cabinet door of cabinet A, is mounted on the cabinet door via a bracket.

[0012] Furthermore, a temperature sensor is installed inside cabinet A.

[0013] Furthermore, the cooling mechanism includes a plate-fin heat exchanger, a cooling fan, a circulating pump, and a coolant storage tank; the plate-fin heat exchanger, the circulating pump, and the coolant storage tank are connected in sequence through corresponding pipes, and the cooling fan is mounted on the plate-fin heat exchanger.

[0014] Furthermore, two sets of plate-fin heat exchangers are provided, and both sets of plate-fin heat exchangers are connected to the circulating pump through corresponding pipelines. A solenoid valve is connected in series in the corresponding pipeline connecting each set of plate-fin heat exchangers to the circulating pump. A cooling fan is provided on each set of plate-fin heat exchangers.

[0015] Furthermore, the back panel of cabinet B is provided with a ventilation opening that communicates with its interior.

[0016] The beneficial effects of this utility model are as follows: This utility model adopts a dual-cabinet design to separate data storage from the coolant cooling mechanism, effectively dissipating heat from the hard drive operating environment in the database management device. This reduces the risk of wear and tear on internal mechanical parts, decreased read and write performance, shortened service life, and data loss caused by high temperatures. At the same time, it effectively avoids the heat generated by the cooling mechanism from affecting the internal environment of the storage hard drive cabinet A, ensuring the stability of the hard drive operating environment.

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] See Figure 1-4 As shown, a database management device includes a pair of cabinets, A1 and B2. Each cabinet has an openable door 3 at its front end. Cabinet A1 contains a mounting base 4 for installing a hard drive, and water-cooled plates 5 for cooling the interior of cabinet A1 and on the inside of its respective door 3 are installed. The mounting base 4 and the water-cooled plates 5 are both mounted within cabinet A1 via a support mechanism 6. Cabinet B2 contains a cooling mechanism 7 connected to the water-cooled plates 5 via corresponding pipes. In use, the cooling mechanism 7 drives coolant to circulate between the cooling mechanism 7 and the water-cooled plates 5, allowing the coolant to absorb and heat the interior of cabinet A1 via the water-cooled plates 5, and then release heat back to the cooling mechanism 7 for cooling.

[0029] Among them, see Figure 4As shown, in this embodiment, four sets of support mechanisms 6 are provided inside the cabinet A1. Each set of support mechanisms 6 includes a pair of support rods 61 fixed inside the cabinet A1. Six sets of mounting plates 62 are arranged from top to bottom between the pair of support rods 61, but not limited to six sets; other numbers can be provided as long as the usage requirements are met. Counting inward from the cabinet opening, the mounting plates 62 on the first and second sets of support mechanisms 6 are at the same installation height, while the mounting plates 62 on the third and fourth sets of support mechanisms 6 are at the same installation height, and the mounting plates 62 on the first and second sets are staggered with those on the third and fourth sets. During installation, the mounting base 4 is placed on the mounting plates 62 on the first and third sets of support mechanisms 6, while the water-cooling plate 5 is placed on the mounting plates 62 on the second and fourth sets of support mechanisms 6.

[0030] Further details can be found by referring to [link / reference]. Figure 4 As shown, in this embodiment, the mounting plate 62 is provided with through holes 621. The through holes 621 are elongated holes and are evenly distributed on the mounting plate 62. The through holes 621 improve the heat flow efficiency between the mounting plates 62, thereby enabling the coolant in the water-cooled plate 5 to absorb heat more quickly, thus improving the heat dissipation efficiency of the cabinet A1.

[0031] Further, see Figure 3-4 As shown, in this embodiment, the water-cooled plate 5, which is located inside the cabinet door 3 of the cabinet body A1, is mounted on the cabinet door 3 by a bracket 8, and the bracket 8 maintains a certain distance between the water-cooled plate 5 and the cabinet door 3.

[0032] Furthermore, in this embodiment, a temperature sensor (not shown in the figure) is installed inside the cabinet A1. The temperature sensor is used to monitor the internal temperature of the cabinet A1 in real time, thereby controlling the start and stop of the cooling mechanism 7.

[0033] Further, see Figure 5-6As shown, in this embodiment, the cooling mechanism 7 includes a plate-fin heat exchanger 71, a cooling fan 72, a circulating pump 73, a coolant storage tank 74, and a solenoid valve 75. Two sets of the plate-fin heat exchanger 71, the cooling fan 72, and the solenoid valve 75 are provided. During installation, a cooling fan 72 is provided on each set of plate-fin heat exchangers 71. The inlets of both sets of plate-fin heat exchangers 71 are connected to the outlet of the circulating pump 73 via corresponding pipes. The inlet of the circulating pump 73 is connected to the outlet of the coolant storage tank 74 via a corresponding pipe. The outlet of the plate-fin heat exchanger 71 is connected to the inlet of the water-cooled plate 5 via a corresponding pipe, and the outlet of the water-cooled plate 5 is connected to the inlet of the coolant storage tank 74 via a corresponding pipe. A solenoid valve 75 is connected in series in the corresponding pipes connecting the plate-fin heat exchanger 71 and the circulating pump 73.

[0034] In use, when the temperature monitored by the temperature sensor reaches a first set threshold, the circulation pump 73 starts, and simultaneously, one set of solenoid valves 75 opens. At this time, under the action of the circulation pump 73, the coolant flows from the coolant storage tank 74 through the pipeline into the finned heat exchanger 71 connected to the opened solenoid valves 75 for cooling. After cooling, it is transported into the water-cooled plate 5 to absorb heat from the cabinet A1. Then, it is discharged through the outlet of the water-cooled plate 5 and flows back to the coolant storage tank 74 through the pipeline, forming a circulation. This continuously absorbs heat from the cabinet A1, thereby achieving continuous cooling of the interior of the cabinet A1. However, when the valve is opened... With one set of solenoid valves 75 in operation, if the temperature of cabinet A1 continues to rise and reaches the second set threshold of the temperature sensor, another set of solenoid valves 75 will open, allowing both sets of plate-fin heat exchangers 71 to simultaneously cool the coolant. This keeps the coolant entering the water-cooled plate 5 at a lower temperature, thereby more efficiently absorbing heat from cabinet A1 and ensuring that the internal temperature of cabinet A1 can be stably controlled within a safe range. To prevent the coolant from the outlet of one fin heat exchanger 71 from entering the other fin heat exchanger 71 while one set of fin heat exchangers 71 is running, a one-way valve 76 is provided at the outlet of each fin heat exchanger 71.

[0035] In this embodiment, the back panel of the cabinet B2 is provided with a ventilation opening 21 that communicates with its interior, and the ventilation opening 21 is directly opposite the cooling fan 72.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
