Description

Technical Field

[0001] This utility model relates to the field of fuel cell stack heat dissipation, and in particular to an air-cooled heat sink. Background Technology

[0002] In current fuel cell reactor processes, the generated high-temperature gases must be cooled to ensure they do not adversely affect subsequent processes. However, currently widely used heat sinks primarily rely on finned fans for heat dissipation, which is not ideal for fuel cell reactor environments. Attempting to improve heat dissipation efficiency by increasing the area of ​​the heat exchange fins and using more powerful fans inevitably leads to a significant increase in the size of the heat dissipation equipment, thus affecting its miniaturization design. Therefore, there is an urgent need to develop a new type of heat sink with high heat exchange efficiency and a smaller footprint to meet the heat dissipation requirements of fuel cell reactor environments. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an air-cooled radiator that solves the problems of low heat dissipation efficiency and large space occupation.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A wind-cooled heat sink includes a fan, a first cavity structure, a second cavity structure, and multiple capillary square tubes. The multiple square tubes are arranged in parallel from top to bottom. One end of each square tube is connected to the first cavity structure, and the other end of each square tube is connected to the second cavity structure. The first cavity structure and the second cavity structure are detachably connected by a threaded rod. The fan is fixedly installed on the first cavity structure and the second cavity structure corresponding to the position of the square tubes. Heat sinks are provided between adjacent square tubes. The heat sinks are arranged perpendicular to the plane where the fan is located. An air inlet and an air outlet are provided on the first cavity structure.

[0005] Furthermore, the heat sink is an aluminum corrugated heat dissipation strip.

[0006] Furthermore, the square tube and the heat sink are bonded together with thermally conductive gel.

[0007] Furthermore, the heat sink at odd-numbered positions of the first cavity structure is provided with a partition, and the heat sink at even-numbered positions of the second cavity structure is provided with a partition.

[0008] Furthermore, the fan is mounted on the first cavity structure and the second cavity structure via a transition plate.

[0009] Furthermore, the transition plate is equipped with shock-absorbing pads to reduce vibration and noise generated during fan operation.

[0010] Furthermore, a dustproof screen is installed at the air inlet to prevent dust from entering the radiator and affecting its heat dissipation effect.

[0011] This invention provides an air-cooled heat sink, comprising a fan, a first cavity structure, a second cavity structure, and multiple capillary square tubes. The multiple square tubes are arranged parallel from top to bottom. One end of each square tube communicates with the first cavity structure, and the other end communicates with the second cavity structure. The first and second cavity structures are detachably connected by threaded rods. The fan is fixedly mounted on the first and second cavity structures corresponding to the positions of the square tubes. Heat sinks are arranged between adjacent square tubes, perpendicular to the plane of the fan. The first cavity structure has an air inlet and an air outlet. In this way, the fan generates airflow, which carries away heat through the heat sinks. The heat sinks then conduct heat away from the square tubes through heat exchange with the multiple capillary square tubes. The design of connecting one end of each square tube to the first cavity structure and the other end to the second cavity structure allows for efficient heat transfer between the two cavity structures. The advantages of this air-cooled heat sink are mainly reflected in its high heat dissipation efficiency and small footprint. First, the use of multiple parallel capillary square tubes combined with heat exchange fins significantly increases the heat dissipation area, thereby improving heat dissipation efficiency. Simultaneously, the heat exchange fins are positioned perpendicular to the fan plane, allowing airflow to make more thorough contact with the fins, further enhancing the cooling effect. Second, the structure of this radiator, combining capillary square tubes with heat exchange fins, not only facilitates assembly and maintenance but also makes the entire radiator more compact, occupying less space and suitable for various space-constrained applications.

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figures 1-4As shown, this utility model provides an air-cooled heat sink, including a fan 1, a first cavity structure 2, a second cavity structure 3, and multiple capillary square tubes 4. The multiple square tubes are arranged parallel from top to bottom. One end of each square tube is connected to the first cavity structure 2, and the other end is connected to the second cavity structure 3. The first cavity structure 2 and the second cavity structure 3 are detachably connected by threaded rods. The fan 1 is fixedly mounted on the first cavity structure 2 and the second cavity structure 3 corresponding to the positions of the square tubes. Heat sinks 5 are arranged between adjacent square tubes, and the heat sinks 5 are arranged perpendicular to the plane of the fan 1. The first cavity structure 2 is provided with an air inlet 6 and an air outlet 7. In this way, the airflow generated by the fan 1 carries away heat through the heat sinks 5, and the heat sinks 5 conduct heat out of the square tubes through heat exchange with the multiple capillary square tubes 4. One end of the square tube is connected to the first cavity structure 2, and the other end is connected to the second cavity structure 3. This design allows for efficient heat transfer between the two cavity structures. The advantages of this air-cooled radiator are mainly reflected in its high heat dissipation efficiency and small footprint. First, the use of multiple parallel capillary square tubes 4 combined with heat exchange fins 5 greatly increases the heat dissipation area, thereby improving heat dissipation efficiency. Simultaneously, the heat exchange fins 5 are positioned perpendicular to the plane of the fan 1, allowing the airflow to make more thorough contact with the heat exchange fins 5, further enhancing the heat dissipation effect. Second, the radiator's structure, which combines capillary square tubes 4 with heat exchange fins 5, not only facilitates assembly and maintenance but also makes the entire radiator more compact, occupying less space and suitable for various space-constrained applications.

[0022] Example 1:

[0023] like Figures 1-4 As shown, an air-cooled heat sink is provided. The main components of the air-cooled heat sink include a fan 1, a first cavity structure 2, a second cavity structure 3, and multiple capillary square tubes 4.

[0024] Fan 1 is the power source of the entire cooling system. Its rotation generates a powerful airflow to remove heat from inside the heat sink. Fan 1 is fixedly mounted on the first cavity structure 2 and the second cavity structure 3, corresponding to the position of the square tube, ensuring that the airflow can directly blow over the square tube and the heat sink 5, thereby improving heat dissipation efficiency.

[0025] The first cavity structure 2 and the second cavity structure 3 are the main parts of the heat sink. They are detachably connected by threaded rods. This design not only facilitates assembly and maintenance but also allows users to replace or upgrade heat sink components as needed. These square tubes are arranged in parallel from top to bottom, with one end connected to the first cavity structure 2 and the other end connected to the second cavity structure 3, forming a heat dissipation path. In this path, the high-temperature gas after the fuel cell reactor reaction is completed circulates within the square tubes, carrying away the heat generated by the fuel cell reactor through heat exchange.

[0026] Heat sinks 5 are installed between adjacent square tubes. These heat sinks 5 are arranged perpendicular to the plane where the fan 1 is located, which effectively increases the heat dissipation area and improves the heat dissipation efficiency.

[0027] The first cavity structure 2 is equipped with an air inlet 6 and an air outlet 7, the design of which is crucial. The air inlet 6 allows cool outside air to enter the radiator and exchange heat with the heat sink 5 and square tube; while the air outlet 7 exhausts the heated air to the outside of the radiator, forming a complete heat dissipation cycle. To ensure the performance and lifespan of the radiator, a dust filter is also installed at the air inlet 6 to prevent dust from entering the radiator and affecting its heat dissipation effect. The dust filter design is both practical and aesthetically pleasing, effectively blocking dust and debris from entering the radiator without affecting airflow.

[0028] It should be noted that the air inlet 6 and the air outlet 7 can be set on the first cavity structure 2, the second cavity structure 3, or respectively on the first cavity structure 2 and the second cavity structure 3, depending on the actual usage requirements.

[0029] The beneficial effects of this air-cooled radiator are mainly reflected in the following aspects: First, through the combined action of fan 1 and heat sink 5, the heat generated by the fuel cell stack can be quickly removed, ensuring that the equipment maintains a stable temperature when operating under high load; second, the precise design of capillary square tube 4 and cavity structure enables high-temperature exhaust gas to circulate efficiently inside the radiator, further improving heat dissipation efficiency; finally, the detachable connection design makes the radiator easy to assemble and maintain, reducing operating costs.

[0030] Furthermore, this air-cooled heatsink boasts excellent compatibility and scalability. It is suitable for various types and sizes of electronic devices; simply select the appropriate heatsink model based on the device's cooling requirements. Moreover, as the performance of electronic devices continues to improve and cooling demands increase, users can enhance the heatsink's performance by replacing the heatsink with a larger fin, increasing the number of fans, or upgrading the coolant.

[0031] In summary, this air-cooled heat sink, with its unique design, high-efficiency heat dissipation performance, and excellent compatibility, is an ideal choice for cooling high-performance electronic equipment. It not only ensures that the fuel cell stack maintains a stable temperature under high load operation, but also extends the equipment's lifespan and improves user satisfaction.

[0032] Example 2:

[0033] like Figures 1-4 As shown, based on Embodiment 1, we improved the heat sink 5 by using an aluminum corrugated heat dissipation strip. This heat dissipation strip not only has good thermal conductivity, but also a larger heat dissipation area and better airflow performance.

[0034] The aluminum corrugated heat sink is made of high-quality aluminum alloy, possessing excellent thermal conductivity and lightweight properties. Compared to traditional flat heat sinks, the corrugated shape provides a larger heat dissipation area within the same volume, allowing heat to dissipate into the air more quickly. Simultaneously, the corrugated shape increases airflow turbulence, enabling more efficient heat exchange between the air and the heat sink as it flows over the heat sink, further improving heat dissipation efficiency.

[0035] In addition to improved heat dissipation performance, aluminum corrugated heat sinks are also aesthetically pleasing and durable. The corrugated design makes the heat sinks look more stylish and dynamic, enhancing the overall visual appeal of the radiator. Furthermore, aluminum alloy has excellent corrosion and oxidation resistance, allowing it to withstand high temperatures and prolonged use without deformation or damage.

[0036] The use of corrugated aluminum heat sinks significantly improves the heat dissipation performance of air-cooled radiators. Under the same cooling conditions, radiators with corrugated heat sinks can dissipate heat generated by electronic devices more quickly, keeping the device temperature at a lower level. This not only extends the lifespan of the equipment but also improves its performance and stability.

[0037] Furthermore, aluminum corrugated heat sink strips are easy to process and install. They can be customized to the size and shape of the radiator to ensure a perfect match. Installation is also very simple and convenient; simply fix them to the appropriate positions on the radiator.

[0038] In summary, air-cooled heat sinks using aluminum corrugated heat dissipation strips offer significant advantages in terms of heat dissipation performance, aesthetics, durability, and ease of manufacturing. These heat sinks are not only suitable for fuel cell reactors but can also be widely used in various applications requiring efficient heat dissipation, such as industrial equipment and communication equipment.

[0039] Example 3:

[0040] like Figures 1-4 As shown, based on Embodiment 1 and Embodiment 2, we further optimized and improved the structure of the heat sink. Specifically, we changed the connection method between the square tube and the heat sink 5 to thermally conductive gel bonding, and added partitions and shock-absorbing pads to the first cavity structure 2 and the second cavity structure 3.

[0041] Thermally conductive gel is a highly efficient heat-conducting material with excellent thermal conductivity and good adhesion. Using thermally conductive gel to bond the square tube to the heat sink 5 significantly reduces the thermal resistance between them and improves heat exchange efficiency. Simultaneously, the flexibility of the thermally conductive gel can absorb some of the vibration and noise generated by the operation of the fan 1, thereby improving the overall performance and stability of the heat sink.

[0042] Another important improvement is the inclusion of partitions in the first cavity structure 2 and the second cavity structure 3. These partitions divide the heat sink 5 into different areas, forming a serpentine pathway. This design not only improves the heat dissipation efficiency of the heat sink but also avoids heat interference and mutual influence between different areas. Specifically, partitions are provided for the heat sink 5 at odd-numbered positions in the first cavity structure 2, and partitions are also provided for the heat sink 5 at even-numbered positions in the second cavity structure 3.

[0043] In addition, we have installed a transition plate 8 between the fan 1 and the cavity structure, and installed vibration damping pads on the transition plate 8. These vibration damping pads are made of high-quality elastic material and have good vibration damping and noise reduction performance. They can absorb the vibration and noise generated by the fan 1 during operation, thereby further improving the overall performance and stability of the heat sink. At the same time, the design of the transition plate 8 can also make the installation of the fan 1 more secure and reliable, avoiding loosening or damage due to long-term use.

[0044] Through the implementation of these improvements and optimizations, the heat dissipation performance, stability, and durability of the air-cooled radiator have been significantly enhanced. Under the same heat dissipation conditions, the radiator with these improvements can remove the heat generated by electronic devices more quickly and maintain device temperature stability better. At the same time, these improvements can also effectively reduce the noise and vibration levels during radiator operation, improving user comfort and satisfaction.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
