Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a crossflow fan radiator structure. Background Technology

[0002] With the rapid development of electronic devices, especially high-performance computers, servers, communication equipment, and high-power LED lighting, the integration and power density of electronic components are constantly increasing, leading to a sharp increase in the heat generated during operation. If this heat cannot be dissipated effectively and in a timely manner, the internal temperature of the equipment will rise rapidly, seriously affecting the operational stability, efficiency, and lifespan of electronic components, and may even cause equipment failure or damage. Therefore, efficient and reliable heat dissipation technology has become one of the key factors in ensuring the long-term stable operation of electronic equipment.

[0003] Currently, common heat dissipation methods mainly include natural convection, air cooling, liquid cooling, and heat pipe cooling. Among them, air cooling is widely used in medium- and high-power electronic devices due to its advantages such as simple structure, low cost, and convenient maintenance. However, most current air cooling solutions use cooling fans, but these fans are noisy, have low airflow, and their heat dissipation effect is not good. Utility Model Content

[0004] The present invention aims to at least solve the technical problems existing in the prior art. To this end, the present invention proposes a crossflow fan heat sink structure that optimizes the heat conduction path, achieves high heat dissipation efficiency, and has a reasonable airflow organization.

[0005] A crossflow fan radiator structure according to some embodiments of the present invention includes a housing, a crossflow fan, a first heat dissipation fin group, a second heat dissipation fin group, and a heat spreader. The first heat dissipation fin group, the second heat dissipation fin group, and the heat spreader are all disposed within the housing. The top of the heat spreader is provided with a plurality of first heat pipes and a plurality of second heat pipes. The heat spreader is located below the first heat dissipation fin group and the second heat dissipation fin group. The first heat pipes pass through the first heat dissipation fin group, and the second heat pipes pass through the second heat dissipation fin group. The crossflow fan is located outside the housing, and a connecting frame is provided around the outer periphery of the crossflow fan. The two sides of the connecting frame are respectively connected to the outer walls of the first heat dissipation fin group and the outer walls of the second heat dissipation fin group.

[0006] A crossflow fan radiator structure according to some embodiments of the present invention has at least the following beneficial effects:

[0007] This invention utilizes a heat spreader plate positioned below the heat source to rapidly absorb and diffuse concentrated heat over a large area, effectively reducing the temperature of local hot spots. Multiple first and second heat pipes then efficiently transfer the heat from the heat spreader plate to the first and second heat dissipation fin groups, forming a low-thermal-resistance heat transfer path. Combined with the lateral airflow generated by the crossflow fan, cooling air can fully flow across the dense fin surface, increasing the contact area and heat exchange time, thus significantly improving convective cooling capacity. Replacing traditional axial or centrifugal fans with a crossflow fan achieves a larger airflow and more uniform air pressure distribution at the same power, making it particularly suitable for narrow, elongated cooling spaces. Simultaneously, the crossflow fan operates smoothly with low noise, enhancing user comfort.

[0010] According to some embodiments of the present invention, a crossflow fan radiator structure is provided with a first clearance groove and a second clearance groove on the top two sides of the housing, and the first connecting plate and the second connecting plate extend into the first clearance groove and the second clearance groove, respectively.

[0011] According to some embodiments of the present invention, a crossflow fan heat sink structure is provided between the outer wall of the first heat sink fin group and the second heat sink fin group, and the first heat pipe and the second heat pipe extend into the clearance gap.

[0024] like Figures 1-3 As shown in the figure, this utility model embodiment provides a crossflow fan heat sink structure.

[0025] A crossflow fan radiator structure includes a housing 1, a crossflow fan 2, a first heat dissipation fin group 3, a second heat dissipation fin group 4, and a heat spreader 5. The first heat dissipation fin group 3, the second heat dissipation fin group 4, and the heat spreader 5 are all disposed within the housing 1. The top of the heat spreader 5 is provided with a plurality of first heat pipes 6 and a plurality of second heat pipes 7. The heat spreader 5 is located below the first heat dissipation fin group 3 and the second heat dissipation fin group 4. The first heat pipes 6 all pass through the first heat dissipation fin group 3, and the second heat pipes 7 all pass through the second heat dissipation fin group 4. The crossflow fan 2 is located outside the housing 1, and a connecting frame 8 is provided on the outer periphery of the crossflow fan 2. The two sides of the connecting frame 8 are respectively connected to the outer walls of the first heat dissipation fin group 3 and the second heat dissipation fin group 4.

[0026] This invention utilizes a heat spreader 5 positioned below the heat source to quickly absorb and diffuse concentrated heat from the heat source over a large area, effectively reducing the temperature of local hot spots. Multiple first heat pipes 6 and second heat pipes 7 efficiently transfer the heat from the heat spreader 5 to the first and second heat dissipation fin groups 3 and 4, respectively, forming a low-thermal-resistance heat transfer path. Combined with the lateral airflow generated by the crossflow fan 2, the cooling air can fully flow across the dense fin surface, increasing the contact area and heat exchange time, thereby significantly improving convective heat dissipation. Replacing traditional axial or centrifugal fans with the crossflow fan 2 achieves a larger airflow and more uniform air pressure distribution at the same power, making it particularly suitable for narrow, elongated heat dissipation spaces. Simultaneously, the crossflow fan 2 operates smoothly with low noise, enhancing user comfort.

[0027] In this embodiment, a crossflow fan radiator structure is described. The connecting frame 8 has a first connecting block 9 and a second connecting block 10 on each side. The first connecting block 9 and the second connecting block 10 are detachably connected to the outer walls of the first heat dissipation fin group 3 and the second heat dissipation fin group 4, respectively. Specifically, the detachable first connecting block 9 and the second connecting block 10 facilitate the installation and removal of the crossflow fan 2 from the first heat dissipation fin group 3 and the second heat dissipation fin group 4, improving the maintainability and assembly flexibility of the radiator and facilitating later cleaning, replacement, or repair of the crossflow fan 2.

[0028] This embodiment describes a crossflow fan radiator structure in which a first connecting plate 11 and a second connecting plate 12 are respectively provided on both sides of the connecting frame 8. The first connecting block 9 and the second connecting block 10 are respectively located on the inner side of the first connecting plate 11 and the inner side of the second connecting plate 12. Specifically, by providing the first connecting plate 11 and the second connecting plate 12 on the connecting frame 8, and placing the first connecting block 9 and the second connecting block 10 on their inner sides, the stability and alignment of the connection structure are enhanced, the connection force distribution is made more uniform, stress concentration is effectively reduced, the mechanical strength and vibration resistance of the overall structure are improved, and the external dimensions are reduced, resulting in a more compact structural design.

[0029] In this embodiment, a crossflow fan radiator structure is described. The top two sides of the housing 1 are respectively provided with a first clearance groove 13 and a second clearance groove 14. The first connecting plate 11 and the second connecting plate 12 extend into the first clearance groove 13 and the second clearance groove 14, respectively. Specifically, by providing the first clearance groove 13 and the second clearance groove 14 on the top of the housing 1, the first connecting plate 11 and the second connecting plate 12 can be embedded inside the housing 1, achieving precise positioning and limiting fit between the connecting frame 8 and the housing 1. This improves the assembly accuracy and stability of the overall structure, enhances the neatness of the appearance, and strengthens the integration of the structure.

Specifically, the clearance gap 15 is provided to accommodate the ends or connection areas of the first heat pipe 6 and the second heat pipe 7, avoiding interference between the heat pipes and adjacent fin groups, ensuring sufficient installation space for the heat pipes, and improving assembly convenience; at the same time, this gap can also serve as an airflow guiding channel, helping to improve local air circulation and enhance heat dissipation uniformity.

[0031] In this embodiment, a crossflow fan radiator structure is described, wherein a first groove 16 is provided at the bottom of the first heat dissipation fin assembly 3, and the first groove 16 is located at the top of the heat spreader 5. Specifically, the first groove 16 is provided at the bottom of the first heat dissipation fin assembly 3 to form a tighter fit with the heat spreader 5 located below, which can be used to accommodate heat pipes, help shorten the heat conduction path, reduce contact thermal resistance, and improve heat transfer efficiency.

[0032] In this embodiment, a crossflow fan heat sink structure is described. The second heat sink fin group 4 has a second groove 17 for accommodating a connector. The second groove 17 is located on the outer side of the second heat sink fin group 4. Specifically, the second groove 17 on the outer side of the second heat sink fin group 4 can be used to accommodate the connector of the PCB board, avoiding interference between the connector and the heat dissipation structure. This protects the connector and improves the utilization efficiency of the internal space of the device, which is beneficial to the miniaturization and modular design of the whole machine.
