[0040] An HDD unit refers to a hard disk drive (HDD). A HDD is a crucial component for storing data in computers and other devices. It primarily consists of a platter, a magnetic head, a motor, and control circuitry. The platter is the medium for storing data, with the magnetic head reading and writing data on the platter surface. The motor drives the platter's high-speed rotation, enabling rapid data access. In servers, desktop computers, laptops, and other devices, HDD units are often used for long-term storage of operating systems, applications, and user data (such as documents, images, and videos). As technology advances, HDD unit power requirements are increasing, necessitating a new solution to address HDD unit cooling requirements.

[0041] See Figure 1 and Figure 2 As shown, a heat dissipation system provided in one embodiment of the present application includes: a box body 100, in which a heat-generating component 200 is provided; a liquid cooling structure 300, which is used to circulate cooling liquid into the box body 100 to cool the heat-generating component 200; and an air cooling structure 400, which is arranged on one side of the box body 100 and forms an air flow for cooling the liquid cooling structure 300.

[0042] In this embodiment, a plurality of heat-generating components 200 are provided in the housing 100, specifically including an HDD unit, and a liquid cooling structure 300 is also provided. The liquid cooling structure 300 is connected to the housing 100 and is used to circulate cooling liquid into the housing 100, thereby enabling immersion heat dissipation to achieve better temperature consistency. The higher specific heat capacity and thermal conductivity of the immersion cooling liquid compared to air can also be utilized to provide better heat dissipation for the heat-generating components 200, thereby improving the heat dissipation efficiency of the heat-generating components 200. Moreover, in this embodiment, an air cooling structure 400 is also provided, and the air cooling structure 400 is used to dissipate heat for the liquid cooling structure 300. With this arrangement, the air cooling structure 400 can be used to cool the liquid cooling structure 300, thereby further improving the heat dissipation efficiency of the liquid cooling structure 300.

[0043] Specifically, the housing 100 includes: a first housing 110, in which some heat-generating components 200 are arranged; and a second housing 120, in which the first housing 110 and the second housing 120 are connected, in which some liquid cooling structures 300 are arranged, and in which some heat-generating components 200 are also arranged. In this embodiment, the housing 100 includes a first housing 110 and a second housing 120, and an HDD unit is arranged in the first housing 110. In servers, HDD units are usually arranged in a front-to-back array in the front-to-back direction of the chassis to achieve better performance. In this embodiment, the front-to-back array characteristics of the HDD unit can be utilized to allow the coolant to enter the first housing 110, thereby achieving a good cooling effect.

[0044] Devices containing HDD units are typically also equipped with electronic components such as network cards and HBAs. A network interface card (NIC), also known as a network adapter, is a crucial hardware device in computer networks, primarily used to facilitate data communication between computers and the network. An HBA (Host Bus Adapter) is a hardware component that provides connectivity between servers and storage devices, primarily used to connect servers to storage area networks. NICs and HBAs typically consume low power, ranging from a few watts to over ten watts. Compared to HDD units, these electronic components inherently have better heat dissipation performance and lack array characteristics. Therefore, a second housing 120 is provided to house the NIC and HBA. The air cooling structure 400 is disposed within the second housing 120, enabling the cooling of the NIC and HBA within the second housing 120.

[0045] Furthermore, the height of the first housing 110 is greater than that of the second housing 120. The first housing 110 is 4U tall, while the second housing 120 is 1U tall. In the server field, "U" is a unit representing the external dimensions of a server, and is the abbreviation of "Unit." A 1U is approximately 44.45 mm (1.75 inches), while a 4U is 177.8 mm. In this embodiment, the first housing 110 is used to accommodate HDD units. Therefore, a 4U height allows for the first housing 110 to accommodate both a network interface card (NIC) and an HBA. The 1U height, however, is shorter and has limited space, making it more suitable for accommodating NICs and HBAs. Furthermore, a 4U height allows for more space for the liquid cooling structure 300, providing better heat dissipation for the higher-power HDD units. In contrast, since the second housing 120 only requires the air cooling structure 400 to dissipate the lower-power NICs and HBAs, a 1U height is more suitable.

[0046] Furthermore, the second housing 120 is provided with an opening on one side away from the first housing 110. This arrangement facilitates air circulation, allowing outside air to enter the air-cooling structure 400 to dissipate heat from the liquid-cooling structure 300, thereby improving the heat dissipation effect of the liquid-cooling structure 300 on the heat-generating components 200. Furthermore, since the air-cooling structure 400, the network card, and the HBA are all provided on the second housing 120, the air-cooling structure 400 can be used to dissipate heat from the network card and the HBA, thereby meeting their heat dissipation requirements.

[0047] Specifically, a cooling liquid inlet 111 is provided at a first end of the first housing 110, and a cooling liquid outlet 112 is provided at a second end of the first housing 110. Cooling liquid flows through the cooling liquid inlet 111 and the cooling liquid outlet 112 to cool the heat-generating component 200. The cooling liquid inlet 111 and the cooling liquid outlet 112 are arranged on the same plane. In this embodiment, cooling liquid can enter through the cooling liquid inlet 111 and flow out through the cooling liquid outlet 112, thereby cooling the entire HDD unit.

[0048] Furthermore, since the coolant inlet 111 and coolant outlet 112 are positioned on the same plane, the HDD unit can be fully immersed, achieving the best cooling effect. By rationally designing the inlet and outlet positions on the same plane and the internal flow-guiding structure, the coolant can be more evenly distributed across the surface of the cooling object, improving heat exchange efficiency and, in turn, the cooling effect, ensuring stable operation of the device.

[0049] Specifically, the liquid cooling structure 300 includes: a connecting pipe 310, one end of which is connected to the coolant inlet 111 and the other end of which is connected to the coolant outlet 112; a drive assembly 320, which is disposed on the connecting pipe 310 and is used to drive the coolant to flow in the connecting pipe 310; and a heat exchange assembly 330, which is also disposed on the connecting pipe 310 and is connected to the drive assembly 320. The coolant enters the heat exchanger through the drive assembly 320 and is used to dissipate heat. In this embodiment, a closed liquid cooling circulation loop is formed by the coolant inlet 111, the connecting pipe 310, the drive assembly 320, the heat exchange assembly 330, and the coolant outlet 112. The coolant enters the coolant inlet 111, cools the heat-generating component 200 in the first housing 110, and then flows out of the coolant outlet 112 through the connecting pipe 310 driven by the drive assembly 320. The coolant then flows through the heat exchange assembly 330, where the heated coolant exchanges heat with the air. The cooled coolant then flows through the connecting pipe 310 again into the coolant inlet 111, thus forming a complete heat dissipation cycle. With the above arrangement, heat can be dissipated from the heat-generating component 200 through the connecting pipe 310, the drive assembly 320, and the heat exchange assembly 330.

[0050] Furthermore, the drive assembly 320 is a pump body. It includes a pump inlet and a pump outlet. The pump inlet is connected to the coolant outlet 112 via a connecting pipe 310, and the pump outlet is connected to the heat exchange assembly 330 via a connecting pipe 310. The pump body in this embodiment is used to provide power for the circulation of the coolant throughout the entire circulation loop. The pump body pumps the coolant, after cooling it in the first housing 110, into the heat exchange assembly 330, providing driving force for the coolant flow within the heat exchange assembly 330. This allows the coolant to continuously circulate within the circulation loop formed by the first housing 110, the pump body, and the radiator, achieving uninterrupted cooling and heat dissipation of the HDD unit. Furthermore, the pump body's speed can be adjusted to match the server's cooling and heat dissipation requirements. Specifically, the pump body's speed can be increased when the server's cooling demand increases, while the pump body's speed can be reduced when the server's cooling demand decreases. This allows the pump body's power consumption to be adjusted in real time based on demand, thereby reducing energy consumption.

[0051] Specifically, heat exchange assembly 330 is a tube-and-belt heat exchanger. Heat exchange assembly 330 includes a heat exchange inlet and a heat exchange outlet. The heat exchange inlet is connected to the pump outlet via a connecting pipe 310, and the heat exchange outlet is connected to the coolant inlet 111 via a connecting pipe 310. A tube-and-belt radiator is a common type of heat exchange equipment, primarily consisting of two parts: tubes and belts. The "tubes" are typically thin tubes made of metal materials (such as copper, aluminum, etc.). These tubes serve as channels for fluid flow, and the coolant flows within the tubes. The "belts" refer to finned belts, which are typically wavy or have other special shapes and fit tightly around the outside of the tubes. The finned belts increase the surface area of the heat exchanger, enhancing the heat transfer effect and enabling more efficient heat exchange between the fluid in the tubes and the external environment or another fluid. Based on the working principles of heat conduction and heat convection, when the coolant flows in the tube, the cold air contacts the fins outside the tube. The heat of the coolant is conducted to the fins through the tube wall, and then the heat is transferred to the cold air through convection heat exchange between the fins and the cold air, realizing heat exchange between the cold air and the coolant.

[0052] In this embodiment, the air-cooling structure 400 is a fan, located at the first end of the housing 100, and is used to dissipate heat from the heat exchanger. The fan has an air inlet and an air outlet. Air enters through the air inlet, and the movement of the blades causes the air to gain velocity and pressure, before being accelerated and blown out of the fan's air outlet. The heat exchange assembly 330 is located at the fan's air outlet, thereby rapidly pushing air to dissipate heat from the heat exchange assembly 330. In other embodiments, heat dissipation from the heat exchange assembly 330 can also be achieved by providing an air deflector. The air deflector, with its specific design, can guide air along a predetermined path, allowing air to flow more efficiently through the heat exchange assembly 330.

[0053] The present disclosure also provides a server including the above-mentioned heat dissipation system. Through the combined arrangement of the liquid cooling structure 300 and the air cooling structure 400, the heat dissipation effect of the heat-generating component 200 can be maximized, solving the problem that the existing technology cannot meet the heat dissipation requirements of the heat-generating component 200.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
