[0028] The present invention will be further described in detail below with reference to the accompanying drawings.
[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
[0030] Example 1:
[0031] This embodiment relates to a cross-flow heat dissipation module, such as... Figures 1-5 As shown, it includes: a housing 100 and two cross-flow fans 300.
[0032] The housing 100 includes two heat dissipation ducts 200 arranged side-by-side in a left-right direction, connecting the front and rear sides of the housing 100 respectively. Two cross-flow fans 300 are respectively installed within the two heat dissipation ducts 200, driving air from the rear of the housing 100 through the heat dissipation channels to the front of the housing 100, where a cooling airflow is blown out. The cross-flow fans 300 drive a large air volume and deliver a concentrated cooling airflow, providing efficient heat dissipation. Furthermore, the cross-flow fans 300 operate with low noise, ensuring a relatively quiet working environment.
[0033] The heat dissipation module draws air in from the rear and exhausts from the front of the housing 100, with conventional airflow directions similar to traditional heat dissipation modules. This makes installation and replacement easier, eliminating the need for device compatibility adjustments and providing a better user experience. The dual-channel design further enhances the overall airflow of the heat dissipation module. The parallel arrangement of the two channels avoids interference between the two cross-flow fans 300, ensuring stable and efficient airflow. The opposite rotation directions of the two cross-flow fans 300 contribute to greater stability and balance of the heat dissipation module, reducing operating noise and preventing vibrations and abnormal sounds from the housing 100.
[0034] In this embodiment, an air guide baffle 400 is provided inside the housing 100 between the two heat dissipation ducts 200. The air guide baffle 400 separates the two heat dissipation ducts 200 within the housing 100, preventing mutual interference. Simultaneously, the air guide baffle 400 guides the airflow within the heat dissipation ducts 200 to achieve good air intake and exhaust performance. Specifically,
[0035] The air guide baffle 400 is Y-shaped, with its opening facing the front of the housing 100. The rear side of the air guide baffle 400 occupies little space, allowing the heat dissipation duct 200 to have a sufficiently large air intake area, ensuring a large heat dissipation flow. The front side of the air guide baffle 400 separates the air outlets of the two heat dissipation channels, preventing mutual interference between their airflow.
[0036] At the same time, the exhaust area of the heat dissipation channel was reduced, the exhaust air velocity was increased, and the heat dissipation effect of the heat dissipation module was optimized.
[0037] As a preferred embodiment, the air guide baffle 400 has air guide arc surfaces 500 on both sides of its opening to guide the airflow from the heat dissipation channel, making the airflow more concentrated and achieving a better heat dissipation effect. Specifically, the air guide arc surface 500 is recessed towards the center of the housing 100. The air guide arc surface 500 can effectively guide the airflow from the heat dissipation ducts 200 on both sides to the front, ensuring a high airflow velocity and avoiding mutual interference between the airflows of the heat dissipation ducts 200 on both sides. In this embodiment, a corrugated guide groove 600 is provided on the side of the air guide arc surface 500 near the corresponding heat dissipation duct 200. The corrugated guide groove 600 can soften the direct impact of the airflow on the air guide arc surface 500, thereby reducing the operating noise of the heat dissipation module and improving the user experience.
[0038] In this embodiment, the cross-flow fan 300 includes: two shaft seats 310 disposed at the upper and lower ends of the housing 100, an impeller 320 rotatably disposed between the two shaft seats 310, and a drive motor 330 for driving the impeller 320 to rotate. The impeller 320 is made of 30% glass fiber reinforced PBT material, which has high heat resistance and can maintain stable operation at high operating temperatures, improving the overall stability of the heat dissipation module. Of course, in other embodiments, the impeller 320 can also be made of other materials, such as ABS or aluminum alloy. As a preferred embodiment, the edges of the impeller 320 are passivated to reduce the noise generated by the impeller 320 directly cutting the air, making the operation of the heat dissipation module quieter.
[0039] As a preferred embodiment, the impeller 320 has a radius of 20mm, which ensures sufficient heat dissipation while making the heat dissipation module smaller and easier to install. Of course, in other embodiments, the radius of the impeller 320 can also be set to 15mm, 16mm, 17mm, 18mm, 19mm, 21mm, 22mm, 23mm, 24mm, 25mm, etc. In this embodiment, the distance between the two impeller 320 shafts is 65mm, ensuring that the airflow in the two heat dissipation channels does not interfere with each other while remaining relatively concentrated. This also optimizes the size of the heat dissipation module, avoiding excessive occupation of internal space and improving installation and user experience. Of course, in other embodiments, the distance between the two impeller 320 shafts can also be set to 55mm, 57mm, 59mm, 61mm, 63mm, 67mm, 69mm, 71mm, 73mm, 75mm, etc.
[0040] Example 2:
[0041] This embodiment relates to a heat dissipation chassis, such as Figure 6 As shown, it includes: a chassis 700, and a cross-flow heat dissipation module as described in Embodiment 1. The cross-flow heat dissipation module is disposed inside the chassis 700 to form a heat dissipation airflow inside the chassis 700, so that the internal components of the chassis have a good heat dissipation effect and ensure good operation of the equipment.
[0042] In this embodiment, the cross-flow cooling module is located at the bottom of the chassis 700, with the exhaust side facing upwards, to create an upward airflow inside the chassis, carrying away heat and achieving good heat dissipation. The cross-flow cooling module can also be located at the front of the chassis 700, with the exhaust side facing rearwards, to create a front-to-back airflow inside the chassis for heat dissipation. Preferably, multiple cross-flow cooling modules can be provided, such as one with an upward exhaust side at the bottom of the chassis 700 and another with an upward exhaust side at the top of the chassis 700. The two cross-flow cooling modules work together to increase the airflow inside the chassis 700 and concentrate the airflow direction, achieving efficient heat dissipation and a superior user experience.
[0043] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
