Continuous fiber-reinforced high-temperature thermoplastic composites (such as polyphenylene sulfide, polyetheretherketone, and polyimide) have attracted widespread attention due to their excellent comprehensive mechanical properties and good temperature resistance.

[0003] The invention disclosed in application number CN202311259601.X is a 3D printing head for continuous fiber thermoplastic composite materials with infrared-assisted heating. It includes a top frame connected to the 3D printer, a filament feeding module and a printing extrusion module arranged sequentially along the continuous fiber filament feeding direction, and an infrared thermal radiation module for auxiliary heating.

[0004] Existing turbo fans mostly direct airflow towards a fixed area, making it impossible to precisely direct and cool different heat-generating areas according to requirements. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation module with a multi-fan structure to address the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A multi-fan heat dissipation module includes a support frame, which has a first heat dissipation structure and a second heat dissipation structure. The support frame includes a top mounting bracket for mounting a working device. The first heat dissipation structure includes a first side mounting plate and a second side mounting plate arranged around the periphery of the working device, wherein the first side mounting plate and the second side mounting plate are arranged in parallel and spaced apart. Turbine fans are respectively mounted on the outer ends of the first side mounting plate and the second side mounting plate. The first side mounting plate and the second side mounting plate are respectively formed with longitudinal mounting grooves along their length direction. Longitudinal sliding blocks are slidably mounted in the longitudinal mounting grooves. The turbine fans are connected to fan plates, and the fan plates are connected to the longitudinal sliding blocks. The support frame is provided with a first driving member that drives the fan plates to move along the length direction of the longitudinal mounting grooves. The turbine fans are provided with an air inlet and an air outlet. The air outlet is connected to an air guide seat, which is formed with an air blowing port facing the bottom of the working device. The air guide seat can adjust the angle of the air blowing port by swinging longitudinally around the air outlet.

[0008] Furthermore: the air outlet protrudes downwards, and the top of the air guide seat is formed with an air inlet groove. The width of the air inlet groove is greater than the width of the air outlet, and the front and rear end walls of the air outlet fit into the groove wall of the air inlet groove.

[0009] Furthermore: guide strips are installed on the front and rear end walls of the air outlet, and guide blocks are installed at the ends of the guide strips. The front and rear end walls of the air inlet groove are respectively formed with arc-shaped grooves that slide with the guide blocks. The air guide seat can swing longitudinally around the air outlet through the sliding cooperation between the arc-shaped grooves and the guide blocks.

[0010] Furthermore: the air outlet is V-shaped.

[0011] Furthermore, compressible bellows covers are connected between the left and right side walls of the air outlet and the left and right side walls of the air inlet.

[0012] Furthermore, the support frame is also equipped with a third side mounting plate, which is located between the first side mounting plate and the second side mounting plate.

[0028] The present invention will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1-3 As shown, a multi-fan heat dissipation module includes a support frame 1, which is provided with a first heat dissipation structure 11 and a second heat dissipation structure 3. The support frame 1 includes a top mounting bracket 12 for mounting a working device 34. The first heat dissipation structure 11 includes a first side mounting plate 13 and a second side mounting plate 14 arranged around the working device 34. The first side mounting plate 13 and the second side mounting plate 14 are mounted parallel to each other at the bottom of the top mounting bracket 12. Turbine fans 2 are respectively mounted on the outer ends of the first side mounting plate 13 and the second side mounting plate 14. The first side mounting plate 13 and the second side mounting plate 14 are... The turbine fan 2 is formed with a longitudinal mounting groove 15 along its length. A longitudinal sliding block 16 is slidably mounted on the longitudinal mounting groove 15. A fan plate 17 is connected to the turbine fan 2. The fan plate 17 is connected to the longitudinal sliding block 16. The support frame 1 is provided with a first driving member that drives the fan plate 17 to move along the length of the longitudinal mounting groove 15. The turbine fan 2 is provided with an air inlet 21 and an air outlet 22. An air guide seat 23 is connected to the air outlet 22. The air guide seat 23 is formed with an air blowing port 24 facing the bottom of the working equipment 34. The air guide seat 23 can adjust the angle of the air blowing port 24 by swinging longitudinally around the air outlet 22.

[0030] The first mounting plate 13 and the second mounting plate 14 are arranged in parallel and spaced apart. The turbine fans 2 at both ends form a symmetrical double air inlet structure 21, which forms a ring-shaped air duct around the working device 34 through the opposing airflow. This layout increases the air volume compared to the traditional single-sided fan. The longitudinal sliding block 16 cooperates with the first drive component to dynamically adjust the height of the air outlet 24 according to the heat-generating area of ​​the device, improving the targeted heat dissipation. In addition, according to the working environment temperature at the bottom of the working device 34, the air guide seat 23 can swing longitudinally around the air outlet 22 to adjust the airflow direction and adjust the angle of the air outlet 24, ensuring that the air volume blown by the turbine fan 2 is accurately guided to the high-temperature heat-generating area, greatly increasing the heat dissipation range.

[0031] Furthermore, the first driving component is an electric push rod 18 installed on the support frame 1, and the driving end of the electric push rod 18 is connected to the fan plate 17. Through the electric push rod 18, the longitudinal sliding block 16 can be driven to move longitudinally along the longitudinal mounting groove 15, so that the fan plate 17 on which the turbine fan 2 is installed can move longitudinally, and the height of the air outlet 24 at the bottom can be changed, thereby improving the heat dissipation targeting.

[0032] It should be noted that by setting up multiple temperature sensors around the heat-generating area, in conjunction with the DS18B20 digital sensor, the system can automatically adjust the angle of the air outlet 24, and the airflow blown out by the turbine fan 2 can be precisely directed to the high-temperature heat-generating area to achieve precise heat dissipation.

[0033] A drive shaft 25 connects the air guide seat 23 and the air outlet 22. A drive motor is mounted on the fan plate 17, and the drive end of the drive motor is connected to the drive shaft 25. The end of the drive shaft 25 is rotatably connected to the air outlet 22 via a bearing. The drive shaft 25 is rigidly connected to the air guide seat 23. The drive motor drives the drive shaft 25 to rotate, and the air guide seat 23 rotates synchronously when the drive shaft 25 rotates, allowing it to automatically swing to different angles. A temperature sensor and a DS18B20 digital sensor are respectively connected to the drive motor, providing signals and power for the automatic swing angle of the air guide seat 23.

[0034] Furthermore, the air outlet 22 protrudes downwards, and the top of the air guide seat 23 is formed with an air inlet groove 26. The width of the air inlet groove 26 is greater than the width of the air outlet 22, and the front and rear end walls of the air outlet 22 fit snugly against the groove walls of the air inlet groove 26, ensuring the overall air duct sealing. Compressible bellows covers 35 are connected between the left and right side walls of the air outlet 22 and the left and right side walls of the air inlet groove 26, respectively. The bellows covers 35 between the left and right side walls of the air outlet 22 and the air inlet groove 26 are made of compressible materials, such as silicone and a galvanized steel frame, which automatically compensate for gaps when the air guide seat 23 swings or the fan spacing is adjusted, ensuring the air duct sealing.

[0035] Specifically, guide strips 27 are installed on the front and rear end walls of the air outlet 22, and guide blocks 28 are installed at the ends of the guide strips 27. The front and rear end walls of the air inlet slot 26 are respectively formed with arc-shaped grooves 29 that slide with the guide blocks 28. The arc-shaped grooves 29 are arranged with the drive shaft 25 as the center to ensure the stability of the air guide seat 23 when it swings. The air guide seat 23 can swing longitudinally around the air outlet 22 through the sliding cooperation between the arc-shaped grooves 29 and the guide blocks 28. The angle of the air guide seat 23 can be finely adjusted according to the heat generation area to ensure that the air outlet 24 of the air guide seat 23 is precisely oriented towards the high-temperature heat generation area. The sliding trajectory of the guide block 28 in the arc-shaped groove 29 strictly limits the swing path of the air guide seat 23. Through the cooperation between the precision-machined arc-shaped groove 29 and the guide block 28, the precise control of the swing angle of the air guide seat 23 is achieved.

[0036] Furthermore, both the air outlet 22 and the air blower 24 are V-shaped, which can concentrate the airflow of the turbine fan 2 to form a high wind speed. The airflow can cool the heat-generating area while removing debris from the heat-generating area, thus enriching the functionality.

[0037] Furthermore, the second heat dissipation structure 3 includes a third-side mounting plate 31 installed on the support frame 1, located between the first-side mounting plate 13 and the second-side mounting plate 14. The third-side mounting plate 31 has a ventilation slot 32, and a cooling fan 33 is mounted on it. The air outlet 22 of the cooling fan 33 faces the working equipment 34 through the ventilation slot 32. The cooling fan 33 of the third-side mounting plate 31 blows airflow onto the working equipment 34 through the ventilation slot 32 to reduce the operating temperature of the working equipment 34 and prevent equipment failure.

[0038] It should be noted that the working device 34 is a 3D printing head.

[0039] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0040] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
