Description

Technical Field

[0001] This utility model relates to the field of computer hardware heat dissipation technology, and more specifically, to a hard disk storage chassis. Background Technology

[0002] As the primary storage device in a computer, the hard drive carries vital information such as the operating system, applications, and user data. Its stability and security directly impact the reliability of the computer system. Traditional computer cases typically only provide hard drive mounting positions, requiring users to directly fix the hard drive to the side wall of the case or a simple bracket using screws. This installation method lacks effective shock absorption and heat dissipation measures, making the hard drive susceptible to vibrations inside the case, high temperatures, and electromagnetic interference from other devices. Prolonged use can easily lead to hard drive damage and data loss.

[0003] To address the aforementioned issues, existing technologies have proposed several hard drive installation devices, such as the "Computer Hard Drive Installation Device" disclosed in Chinese Patent CN217787709U. This device, through the arrangement of mounting brackets, movable mounting components, and heat dissipation components, achieves modular installation, vibration buffering, and active heat dissipation of hard drives, thereby improving the safety and lifespan of hard drives to a certain extent. However, there is still room for improvement in the coordination of its heat dissipation airflow with the overall airflow of the chassis, its dustproof performance, and its electromagnetic shielding capabilities. Furthermore, this device does not fully consider the spatial layout and heat dissipation efficiency issues when multiple hard drives are installed in parallel, making it difficult to meet the requirements of high-performance computers or servers for multiple hard drive installations and efficient heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide a hard drive storage chassis that solves the problems of hard drive overheating, shortened lifespan, and poor data stability caused by insufficient heat dissipation performance of existing chassis.

[0005] This utility model is achieved through the following technical solution:

[0006] A hard drive storage chassis includes: a chassis body, an operation panel, a heat dissipation assembly, and a hard drive rack. The operation panel is disposed on the surface of the chassis body. The chassis body has a storage space inside. The heat dissipation assembly and the hard drive rack are disposed within the storage space. The hard drive rack is disposed opposite to the heat dissipation assembly. The chassis body has a plurality of air vents, the two ends of which are respectively connected to the storage space and the external space of the chassis body.

[0007] Optionally, the plurality of air vents includes a first air vent located on the front top side of the chassis body, a second air vent located on the front bottom side of the chassis body, a third air vent located on the rear top side of the chassis body, and a fourth air vent located on the rear bottom side of the chassis body, wherein the first air vent, the second air vent, the third air vent, and the fourth air vent are all connected to the storage space.

[0008] Optionally, dust filter components are provided at the first air inlet, the second air inlet, the third air inlet, and the fourth air inlet; wherein, the dust filter components are used to prevent external dust from entering the storage space.

[0009] Optionally, the heat dissipation assembly includes at least one cooling fan, which is located inside the chassis body near the second air inlet or the fourth air inlet.

[0010] Optionally, ventilation channels are formed between both sides of the hard drive rack and the inner wall of the chassis body, and the ventilation channels are connected to the first air inlet, the second air inlet, the third air inlet and the fourth air inlet.

[0011] Optionally, the hard drive rack is provided with a plurality of hard drive mounting slots, and each hard drive mounting slot is provided with a limiting structure for fixing the hard drive.

[0012] Optionally, ventilation holes are provided on the wall of the hard disk mounting slot.

[0013] Optionally, a temperature sensor is provided in the storage space, and the temperature sensor is electrically connected to the operation panel and the heat dissipation component respectively; wherein, the temperature sensor is used to detect the temperature in the storage space and adjust the working state of the heat dissipation component according to the detected temperature.

[0014] Optionally, the operation panel is provided with a display screen and control buttons. The display screen is electrically connected to the temperature sensor and the hard drive on the hard drive rack, respectively, and the control buttons are electrically connected to the heat dissipation assembly. The display screen is used to display the temperature and hard drive operating status information in the storage space, and the control buttons are used to control the start / stop and speed adjustment of the heat dissipation assembly.

[0015] Optionally, the chassis body is made of metal, and a thermally conductive silicone layer is provided on the inner wall of the chassis body, the thermally conductive silicone layer being attached to the hard drive cage.

[0016] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0017] By aligning the heat dissipation components with the hard drive cage and incorporating several air vents on the chassis connecting the internal storage space to the external space, an efficient heat dissipation channel is created. This guides cool external air into the chassis, quickly removing the heat generated by the hard drive's operation, effectively solving the heat accumulation problem caused by inadequate ventilation design in existing chassis. This not only maintains the hard drive at a suitable operating temperature, significantly improving read / write speeds and data transfer stability, but also slows down the aging rate of internal components, extending the hard drive's lifespan and reducing the risk of serious failures such as data loss due to overheating.

[0018] The chassis integrates the control panel, heat dissipation components, and hard drive cages into one unit, with a compact overall structure and clear functional partitions. The hard drive cages provide a unified mounting platform for hard drives, facilitating the centralized placement and orderly arrangement of multiple hard drives, meeting the standardized requirements for hard drive storage. At the same time, the clear structural layout also reduces the difficulty of later maintenance and repair of hard drives and heat dissipation components, improving management efficiency.

[0019] The chassis provides reliable physical protection for the hard drive and avoids interference from external collisions, while achieving synergy between protection and heat dissipation through a scientific heat dissipation structure design; it is suitable for hard drive storage needs in various scenarios such as server rooms, data centers, industrial control, and personal computers, and has strong practicality and broad application prospects.

[0025] The following is a detailed description of the embodiments, in conjunction with the accompanying drawings.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4A hard drive storage chassis includes: a chassis body 1, an operation panel 2, a heat dissipation assembly 3, and a hard drive rack 4. The operation panel 2 is disposed on the surface of the chassis body 1. The chassis body 1 contains a storage space. The heat dissipation assembly 3 and the hard drive rack 4 are disposed within the storage space, with the hard drive rack 4 positioned opposite to the heat dissipation assembly 3. The chassis body 1 has several air vents, each connected at both ends to the storage space and the external space of the chassis body 1. The chassis body 1 can be die-cast from aluminum alloy, balancing structural stability and heat dissipation performance. The internal storage space of the chassis body 1 can be divided into a heat dissipation airflow area and a hard drive installation area by vertical partitions. The two areas are interconnected and unobstructed, ensuring smooth airflow. The chassis surface is anodized, which not only improves corrosion resistance but also enhances surface heat dissipation efficiency. The operation panel 2 can be embedded in the front face of the chassis body 1 and uses a combination of an LCD screen and physical buttons. The display screen shows the real-time internal temperature of the chassis, the operating status of each hard drive (such as read / write speed and health), and the operating parameters of the heat dissipation component 3. Physical buttons include a power switch, fan speed control button, hard drive indicator light switch, and emergency restart button. The operation panel 2 can be connected to the main control module inside the chassis via internal cables. The main control module can use an STM32F103 microcontroller to achieve centralized control and status feedback of each component. The heat dissipation component 3 is located in the heat dissipation airflow area inside the chassis body 1, and is arranged perpendicularly to the hard drive cage 4 (see reference). Figure 4 The hard drive cage 4 can adopt a pull-out modular structure and is connected to the inner side wall of the chassis body 1 via a slide rail. A hinged door panel is set on the back of the chassis body 1. After opening the door panel, the hard drive cage 4 can be completely pulled out of the chassis body 1 for hard drive installation and removal.

[0027] In some embodiments, the plurality of air vents include a first air vent 101 located on the top front side of the chassis body 1, a second air vent 102 located on the bottom front side of the chassis body 1, a third air vent 103 located on the top rear side of the chassis body 1, and a fourth air vent 104 located on the bottom rear side of the chassis body 1. All four air vents (101, 102, 103, and 104) are connected to the storage space. Based on the physical property of hot air rising, cool air enters the internal storage space of the chassis from the second air vent 102 on the bottom front side and the fourth air vent 104 on the bottom rear side. After absorbing the heat generated by the hard drive operation, the hot air is discharged from the first air vent 101 on the top front side and the third air vent 103 on the top rear side, forming a smooth "bottom-in, top-out" convection, significantly improving the airflow efficiency inside the chassis and accelerating heat dissipation. Four air vents are located at the front and back of the top and bottom of the chassis, respectively. Combined with the internal layout of "unobstructed heat dissipation airflow area and hard drive installation area", the airflow can flow evenly through all areas of the hard drive rack, avoiding local heat accumulation when multiple hard drives are working, and ensuring that each hard drive can be effectively cooled.

[0028] In some embodiments, dust filter components are provided at the first air inlet 101, the second air inlet 102, the third air inlet 103, and the fourth air inlet 104; wherein, the dust filter components are used to prevent external dust from entering the storage space. The dust filter components can adopt a "dual-stage interception" composite structure: the outer layer is a nylon mesh to intercept large particulate impurities such as hair and fibers; the inner layer is a thickened flame-retardant polyurethane sponge, which captures dust particles through a three-dimensional mesh structure. This combination ensures airflow efficiency and can meet the long-term dust protection requirements of multi-hard drive operating scenarios. For high-dust environments (such as industrial control scenarios), a labyrinthine secondary filter can be added inside the air inlet to form multiple layers of protection.

[0029] In some embodiments, the heat dissipation assembly 3 includes at least one cooling fan, which is located inside the chassis body 1 near the second air inlet 102 or the fourth air inlet 104. The second air inlet 102 and the fourth air inlet 104 are the cold air inlets of the chassis. By placing the cooling fan near these locations, the cooling fan can upgrade from "passive air intake" to "active air intake", significantly increasing the intake air speed and volume, and avoiding slow air intake caused by insufficient natural convection.

[0030] In some embodiments, ventilation channels are formed between the two sides of the hard drive cage 4 and the inner wall of the chassis body 1. The ventilation channels are connected to the first air inlet 101, the second air inlet 102, the third air inlet 103, and the fourth air inlet 104. The cool air drawn in by the cooling fan will first fill the ventilation channels on both sides (the channels are not blocked by hard drives, so the air resistance is smaller), and then be distributed to the entire hard drive cage through the channels. This is equivalent to providing a "fast delivery pipeline" for cool air, avoiding the airflow from the fan being reduced in speed due to "direct obstruction by hard drives".

[0031] In some embodiments, the hard drive cage 4 is provided with several hard drive mounting slots, each equipped with a limiting structure for securing the hard drive. The limiting structure consists of symmetrically arranged inverted V-shaped elastic buckles on both sides of the mounting slot's inner wall. These buckles are made of spring steel sheets, and in their free state, the inner spacing is smaller than the width of the hard drive. The engaging surfaces are provided with anti-slip serrations. The base of the buckle is integrally injection molded to the hard drive cage, and the front end extends to the front face of the hard drive cage to form a press-to-unlock part. When the hard drive is fully inserted, the buckle automatically engages with the heat dissipation holes on both sides of the hard drive, forming a bidirectional lock with the silicone positioning block at the rear of the mounting slot. During disassembly, pressing the front unlock part causes the buckle to open synchronously, releasing the locked state.

[0032] In some embodiments, ventilation holes are provided on the wall of the hard drive mounting slot. After ventilation holes are provided on the slot wall, the airflow inside the chassis body 1 can directly penetrate the slot wall and enter the interior of the mounting slot, making full contact with the "non-exposed heat dissipation surfaces" such as the side and bottom of the hard drive, quickly removing the heat trapped in the slot, upgrading the heat dissipation from "passive heat dissipation of the exposed surface of the hard drive" to "active convection heat dissipation of the entire surface", significantly reducing the core temperature of the hard drive.

[0033] In some embodiments, a temperature sensor is installed within the storage space, electrically connected to both the operation panel 2 and the heat dissipation component 3. The temperature sensor detects the temperature within the storage space and adjusts the operating state of the heat dissipation component 3 based on the detected temperature. The temperature sensor can monitor the ambient temperature in the hard drive mounting area and airflow channels in real time and accurately, feeding the data back to the main control module. The main control module can automatically adjust the fan speed (e.g., via PWM speed control) based on preset temperature thresholds (e.g., setting low, medium, and high temperature levels). The fan speed is reduced at low temperatures to decrease noise and energy consumption, and increased at high temperatures to enhance cooling performance. This closed-loop control system avoids the drawbacks of traditional chassis cooling systems that operate continuously at full speed or rely on manual adjustment, achieving dynamic matching of cooling capacity, ensuring high efficiency and reliability of heat dissipation, and effectively coping with sudden temperature increases during high-load operation of multiple hard drives.

[0034] In some embodiments, the operation panel 2 is equipped with a display screen and control buttons. The display screen is electrically connected to the temperature sensor and the hard drives on the hard drive rack 4, respectively, and the control buttons are electrically connected to the heat dissipation assembly 3. The display screen displays the temperature and hard drive operating status information within the storage space; the control buttons control the start / stop and speed adjustment of the heat dissipation assembly 3. By integrating the display screen, the operator can read the internal ambient temperature of the chassis and the operating status of each hard drive (such as read / write speed and health) in real time and intuitively. This allows the administrator to grasp the system's operating status immediately, providing early warnings and interventions for potential overheating risks or hard drive failures. This effectively avoids data loss or hardware damage caused by overheating, greatly improving the security and reliability of data storage, while reducing the workload of maintenance personnel who frequently open the chassis for inspection.

[0035] In some embodiments, the chassis body 1 is made of metal, and a thermally conductive silicone layer is provided on the inner wall of the chassis body 1, which is in contact with the hard drive cage 4. The metal chassis body (such as aluminum alloy) is itself an excellent thermal conductor. The heat generated by the hard drive during operation is transferred through the hard drive cage to the thermally conductive silicone layer that is in close contact with it. The thermally conductive silicone has a high thermal conductivity and good flexibility, which can effectively fill the microscopic gaps between the hard drive cage and the inner wall of the chassis, reduce the contact thermal resistance, and thus efficiently and quickly conduct the heat generated by the hard drive to the entire metal chassis shell.
