It is responsible for accurately controlling the read and write operations of the disc, ensuring that data can be transmitted between the disc and the host system at high speed and stability, and is the core component of the entire storage system to ensure smooth operation. With the rapid development of science and technology, electronic devices such as notebook computers, tablet computers, and ultra-thin servers are constantly moving towards miniaturization and lightweight, which requires internal components to be as small as possible. Therefore, the ultra-thin disc controller has emerged as the times require.

[0029] ​The technical scheme in the utility model will be described clearly and completely in combination with the drawings of the utility model.

[0030] Embodiment one: the embodiment constructs a kind of ultra-thin disk controller, and its core component includes controller main body 100, metal heat sink 110, heat-conducting copper pipe 112 and shell 113.

[0031] Firstly, controller main body 100 is the core operation and control unit of the whole controller, and is fixed closely with metal heat sink 110 at bottom by special bonding process, to ensure that high-efficiency heat transfer can be realized between the two.Metal heat sink 110 adopts carefully designed structure, and multiple heat dissipation fins 111 are evenly and vertically distributed at the bottom end of the metal heat sink, which are reasonably spaced from each other to maximize the heat dissipation area, so that heat can be quickly dissipated from the metal heat sink 110 to the surrounding environment, effectively reducing the temperature of the controller main body 100.

[0032] Secondly, heat-conducting copper pipe 112 plays a key role in the heat dissipation system, and one end of the heat-conducting copper pipe is accurately connected to the main chip or power amplifier on the controller main body 100, which are key parts of heat sources prone to high heat. During operation, the main chip needs to continuously perform complex data operation and instruction processing, resulting in large power consumption and thus a large amount of heat. When the power amplifier amplifies the signal, heat is also generated due to energy conversion. The heat-conducting copper pipe 112 quickly conducts the heat generated by the heat sources to the other end by virtue of the excellent heat conduction performance of the copper pipe inside. The other end of the heat-conducting copper pipe 112 is seamlessly connected to the heat dissipation fins 111, forming a smooth and unobstructed heat conduction channel to ensure that heat can be smoothly transferred from the heat source to the heat dissipation fins and then dissipated to the outside.

[0033] Furthermore, the shell 113 is made of plastic material with high thermal conductivity, which has good heat conduction characteristics while ensuring a certain structural strength, and can assist in dissipating heat from the inside. The outer surface of the shell 113 is regularly arranged with micro heat dissipation holes 114, and the diameter, spacing and arrangement of these heat dissipation holes are precisely calculated to maintain the ultra-thin structure of the entire controller while effectively ensuring the efficient exchange rate of heat and outside air, so as to ensure that the internal heat can be discharged in time.

[0034] Embodiment two:

[0035] Based on embodiment one, embodiment two makes further optimization and improvement.

[0036] In one aspect, the shell 113 is manufactured using an advanced one-piece molding process. During the molding process, the shell 113 is effectively ensured to be stable in structure and able to withstand a certain degree of external force impact and vibration, and the sealing performance is greatly improved, effectively preventing the intrusion of external dust, moisture and other impurities into the internal precision components, thereby providing a relatively clean and stable operating environment for the internal electronic components.

[0037] On the other hand, considering the convenience of later maintenance and repair of the device, the shell 113 can also be designed as a split innovative structure, specifically composed of a base 115 and an upper cover 116. The two are combined together through a convenient detachable connection method, such as a buckle connection or screw fixation, etc. When it is necessary to perform routine maintenance, quick repair and timely replacement of parts, the operator can easily detach the upper cover 116 and conveniently access the internal controller main body 100, heat dissipation components and other key components, thereby greatly improving the work efficiency.

[0038] Meanwhile, a mounting groove 117 is cleverly provided at the bottom end of the shell 113, and a small heat dissipation fan 118 is precisely fitted inside the mounting groove 117. The small heat dissipation fan 118 is driven by a low-noise, high-speed brushless DC motor, and the noise generated during operation is controlled below the industry standard, while having energy-saving characteristics. Under high temperature working conditions, when the internal temperature of the controller reaches a certain threshold, the small heat dissipation fan 118 can be automatically started to realize forced air cooling auxiliary heat dissipation function, which cooperates with the heat dissipation fins 111 and the metal heat dissipation plate 110 to provide strong heat dissipation protection for the device, ensuring stable operation of the controller in high temperature environment.

[0039] In addition, the pore size of the micro heat dissipation hole 114 is strictly limited and precisely controlled within a specific range of 0.1-0.25 mm. Such a fine design not only ensures smooth air flow for efficient heat dissipation, but also effectively blocks the invasion of dust particles, thereby maintaining a clean internal operating environment and reducing problems such as poor heat dissipation or electronic component short circuit caused by dust accumulation.

[0040] Furthermore, the metal heat dissipation plate 110 is explicitly limited to use high-quality aluminum alloy material, and its thickness is strictly controlled within a narrow range of 0.5-1 mm through a precise process. The aluminum alloy material itself has excellent heat conduction performance and can quickly conduct heat away, and the strictly controlled thickness not only fully meets the high-strength heat dissipation requirement, but also perfectly adapts to the strict space constraints brought by the ultra-thin design, so that the entire controller realizes ultra-thin design while ensuring heat dissipation performance.

[0041] In addition, in order to further enhance the sealing performance of the split structure of the shell, the connecting part of the base 115 and the upper cover 116 is subjected to secondary sealing treatment by using a sealing rubber strip. On the basis of being detachable, the sealing rubber strip effectively fills the small gap of the connecting part, further enhances the sealing performance of the whole shell, effectively resists external invasion in a humid environment or a scene with more dust, and ensures the reliability and stability of the internal electronic components.

[0042] Finally, the surface of the heat dissipation fin 111 is coated with a nano coating. The nano coating has super heat dissipation performance and hydrophobicity, which can accelerate the dissipation of heat from the surface of the heat dissipation fin to the air, improve the heat dissipation efficiency, and on the other hand, the hydrophobicity can effectively prevent water vapor from condensing on the surface of the fin, avoid affecting the heat dissipation efficiency due to water vapor accumulation, and ensure that the controller can still operate stably in a complex environment, such as a high humidity environment.

[0043] Through the above two embodiments, the structural characteristics, heat dissipation principle and optimization scheme under different design requirements of the ultra-thin disc controller are comprehensively displayed, so that it can meet the diversified application scenarios and performance requirements.

[0044] Finally, it should be pointed out that: first, in the description of the present application, it should be pointed out that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, which can be mechanical connection or electrical connection, or the communication between two elements, or direct connection, "up", "down", "left", "right" and the like are only used to indicate the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;

[0045] Secondly: the utility model discloses the embodiment of the drawings, only relate to the structure involved in the embodiment of the present disclosure, other structures can refer to the usual design, in the case where there is no conflict, the same embodiment and different embodiments of the utility model can be combined with each other;

[0046] Finally: the above is only the preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
