Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and in particular to a heat dissipation structure for a radiator and a liquid cooling system. Background Technology

[0002] With technological advancements, such as the development of AI, various complex applications like deep learning and big data processing are constantly emerging, demanding faster processing speeds and stronger computing power from electronic products' chips. Similarly, computer processors need to unleash powerful performance when running complex programs like professional graphics rendering and AI training, as well as high-definition games. This performance release inevitably leads to heat generation. With the support of existing water-cooling technology, water-cooled radiators can effectively address the cooling requirements of components, ensuring that critical hardware such as processors and graphics cards maintain low temperatures even during high-performance operation, guaranteeing stable performance output and meeting the high-performance requirements of technological development for electronic products.

[0003] Currently, water cooling primarily relies on radiators to lower the liquid temperature, and the radiator's heat dissipation structure significantly impacts the overall efficiency of the water cooling system. For example... Figure 6 As shown, most existing radiators use a structure primarily consisting of corrugated fins 610 and flat tubes 620, employing a design where the corrugated fins 610 are stacked in two layers of flat tubes 620. Because the corrugated fins 610 and flat tubes 620 are only in near-line contact, the efficiency of heat transfer from the coolant inside the flat tubes 620 to the corrugated fins 610 is severely limited, thus affecting the overall cooling effect of the water cooling system and failing to meet the increasing heat dissipation demands of high-performance electronic devices. Furthermore, the flat tubes 620 are mostly arranged in parallel, easily causing uneven heat dissipation in certain areas, leading to heat accumulation that cannot be dissipated in time. This can result in the risk of performance degradation or even damage to electronic components during operation due to localized overheating, making it difficult to ensure stable operation of electronic components within a suitable temperature range. This can easily lead to equipment crashes, restarts, and other malfunctions, affecting normal equipment use and business continuity. Therefore, developing a radiator heat dissipation structure that can effectively improve heat dissipation efficiency is particularly important. Utility Model Content

[0029] like Figure 1 and Figure 2 As shown in the figure, this application provides a radiator heat dissipation structure, including a fin assembly 100 and a radiator tube 200. The fin assembly 100 is formed by stacking multiple spaced fins 110 one after the other. Each fin 110 has a through hole 111, and a wrapping ring 112 is provided between two adjacent fins 110. The front and rear ends of the wrapping ring 112 are respectively connected to the two adjacent through holes 111, thus forming a tightly connected contact heat exchange channel. Simultaneously, the radiator tube 200 passes through the contact heat exchange channel formed by the through holes 111 and the wrapping ring 112 of the fin assembly 100. The outer wall of the radiator tube 200 contacts the inner walls of the through holes 111 and the wrapping ring 112, allowing the liquid inside the radiator tube 200 to transfer heat to the fin assembly 100, thereby achieving heat dissipation.

[0030] The advantage of the radiator heat dissipation structure in this application embodiment is that it adopts a unique fin group 100 design, and uses the wrapping ring 112 between the fins 110 to be tightly connected with the through holes 111 at the front and rear ends. The wrapping ring 112 increases the contact area between the fins 110 and the radiator tube 200, so that the heat of the radiator tube 200 can be transferred to the fins 110 through the wrapping ring 112, thereby greatly improving the heat transfer efficiency and enhancing the overall heat dissipation effect.

[0031] As an example, see Figure 2The fin 110 includes a planar side 101 and a raised side 102. The raised side 102 protrudes outward to form a wrapping ring 112 surrounding the through hole 111. The wrapping ring 112 is integrally formed by stamping the fin 110. The wrapping ring 112 of the raised side 102 of one fin 110 is connected to the through hole 111 of the planar side 101 of another fin 110. In this embodiment, the fin 110 is made of metal sheet, such as aluminum alloy sheet. Through a stamping process, the fin 110 with the through hole 111 and the outwardly protruding wrapping ring 112 on one side is stamped on the sheet, so that the fin 110 is divided into a planar side 101 and a raised side 102 with the wrapping ring 112. The manufacturing process is simple and efficient, which helps to reduce costs. The stamped fins 110 are then stacked with their planar sides 101 and raised sides 102 facing each other, so that the wrapping ring 112 of the raised side 102 of one fin 110 is tightly abutted with the through hole 111 of the planar side 101 of the adjacent fin 110, thereby forming a fin assembly 100. During the stacking process, appropriate tight-fitting fixing methods, such as welding or riveting, can be used to ensure the stability of the fin assembly 100.

[0032] As an example, see Figure 1 and Figure 2 Both the through hole 111 and the radiator tube 200 have circular cross-sections. The outer diameter of the radiator tube 200 matches the diameter of the through hole 111 of the fin 110. Compared with the flat tube structure, the circular tube structure has a better water flow speed under the same power water pump drive, which can improve the flow efficiency and heat exchange effect of the coolant.

[0033] As an example, a heat-absorbing layer 210 is provided on the inner wall of the radiator pipe 200 to further improve heat dissipation efficiency and optimize heat dissipation effect. See also Figure 3 The heat-absorbing layer 210 can be configured as a grooved structure to increase the contact area between the coolant and the inner wall of the radiator pipe 200, thereby improving heat exchange efficiency. In another embodiment, see... Figure 4 The heat-absorbing layer 210 can also be formed by sintering copper powder with the inner wall of the cooling tube 200 to form a structure with fine gaps, which increases the heat-absorbing area and improves the heat absorption capacity, enabling it to absorb and transfer heat from the liquid more quickly.

[0034] Based on the same inventive concept as the aforementioned radiator heat dissipation structure, this application also provides a liquid cooling heat dissipation system, see [link to relevant documentation]. Figure 5The system includes a fan 300, a cold block 400, water pipes 500, and the radiator cooling structure described above. The cold block 400 is connected to the radiator pipes 200 in the radiator cooling structure via the water pipes 500 to form a liquid cooling circuit. The fan 300 drives airflow to exchange heat with the radiator cooling structure. The fan 300 is installed on one side of the radiator cooling structure, and its position and angle should be adjusted according to actual cooling requirements to ensure that the air blown by the fan 300 can fully exchange heat with the radiator cooling structure. The liquid cooling system of this application achieves efficient heat dissipation circulation by using the fan 300 to drive air to exchange heat with the radiator cooling structure, combined with the liquid cooling circuit, ensuring that the equipment maintains a low temperature under various operating conditions. It is suitable for high-performance computers, servers, game consoles, and other equipment requiring efficient heat dissipation.

[0035] The working principle of the liquid cooling system is as follows: When the electronic equipment generates heat, the coolant absorbs heat in the cold head 400, causing its temperature to rise. Then, the high-temperature coolant flows through the water pipe 500 into the radiator tubes 200 of the radiator cooling structure, and transfers heat to the fin assembly 100 through the radiator tubes 200. Because the fins 110 of the fin assembly 100 are in close contact with the radiator tubes 200, heat can be quickly transferred to the fins 110. Simultaneously, the fan 300 drives airflow; as the air flows past the fin assembly 100, it carries away the heat from the fins 110, achieving heat dissipation. The cooled coolant then flows back to the cold head 400 through the water pipe 500 to continue absorbing heat generated by the electronic equipment, thus completing the cycle and ensuring the stable operation of the electronic equipment.

[0036] It should also be noted that, without conflict, the embodiments of this utility model and the features therein can be combined with each other to obtain new embodiments.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. The scope of protection of the present utility model should be determined by the scope of the claims. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
