[0027] In the related art, when multiple cooling fans are tightly integrated into the same heat dissipation module, the independent test lines will cause a series of problems for the client. For example, multiple test lines will increase the difficulty of wiring the client, and the interlacing and entanglement between the test lines will affect the neatness inside the module, and also hinder the air flow, thereby affecting the heat dissipation efficiency of the module.

[0028] Therefore, in order to solve the above technical problems, the present application provides a snap-on device and a heat dissipation module.

[0029] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0030] Figure 1 Shown is a schematic structural diagram of a buckle device in an embodiment of the present application.

[0031] See also Figure 1 A buckle device 10 includes a buckle body 110 and a buckle kit 120. It should be noted that the buckle body 110, as a core structural component, bears the dual tasks of electrical connection and mechanical fixation. The structural design of the buckle body 110 ensures precise docking with the cooling fan probe, ensures good contact, and stable and reliable signal transmission. The buckle kit 120 is a kit for connecting two adjacent cooling fans in series.

[0032] See also Figure 1 The buckle body 110 is provided with contact pieces 111 at both sides, and the contact pieces 111 are provided with a plurality of contact foil points (not shown in the figure). It should be noted that the contact pieces 111 provided on both sides have a plurality of contact foil points, each of which is an electrical contact point, which is used to receive and transmit the working status signal of the cooling fan, such as the speed, temperature and other information, so as to realize the real-time test, monitoring and control of the running status of the cooling fan.

[0033] See also Figure 1 The buckle kit 120 includes two elastic buckle arms 121, which are axially symmetrically distributed with respect to the central axis of the buckle body 110, and the two elastic buckle arms 121 are connected to the buckle body 110, and the ends of the two elastic buckle arms 121 connected to the buckle body 110 are provided with a clamping protrusion 1211. It should be noted that the elastic buckle arm 121 is one of the most important components of the buckle device 10, and its design adopts an axially symmetrical distribution method, which enables the buckle device 10 to evenly apply the installation force to the cooling fan, thereby improving the installation stability of the buckle device 10. When subjected to appropriate external force, the two elastic buckle arms 121 will deform toward each other, and the clamping protrusion 1211 at the end thereof can be accurately embedded in the buckle hole of the cooling fan to form a stable mechanical connection, thereby preventing the connection from loosening due to vibration and other reasons during operation.

[0034] For further information, see Figure 1 In one embodiment, both elastic buckle arms 121 are provided with a pressing portion 1212. It should be noted that the structure of the pressing portion 1212 is a structure protruding outward, providing a position for the operator to press the buckle arm 1211, so that the operator can more easily press down the elastic buckle arm 121, so that the elastic buckle arms 121 on both sides are deformed toward each other, so that the buckle device 10 is more easily buckled into the cooling fan, thereby improving the buckling efficiency.

[0035] For further information, see Figure 1 In one embodiment, the buckle body 110 is provided with a number of clearance grooves 112 equal to the number of the protrusions 1211, and each protrusion 1211 is located in each clearance groove 112 in a one-to-one correspondence. It should be noted that the clearance grooves 112 and the protrusions 1211 are a pair of precisely matched structural units. By providing a number of clearance grooves 112 equal to the number of the protrusions 1211 on the buckle body 110, the protrusions 1211 can be accurately positioned after elastic deformation, achieving seamless docking with the buckle hole of the cooling fan, thereby improving the accuracy and reliability of the connection. At the same time, the structural design of the clearance grooves 112 can also make the structure of the buckle device 10 more compact and minimize the overall volume of the buckle device 10.

[0036] For further information, see Figure 1 In one embodiment, the buckle device 10 further includes two reinforcing tabs 130, and the two reinforcing tabs 130 are axially symmetrically distributed about the central axis of the buckle body 100. It should be noted that the reinforcing tabs 130 increase the overall strength and deformation resistance of the buckle device 10. In other embodiments, the two reinforcing tabs 130 and the buckle body 110 can also be designed as an integrally formed structure, which greatly improves production efficiency and product quality. This structural design not only meets the requirements of high strength and high precision, but also reduces manufacturing costs and assembly difficulty. More importantly, the reinforcing tabs 130 on both sides enable the buckle device 10 to contact the wind shell of the cold fan when it is installed on the cold fan, so that the buckle device 10 can be more stably reinforced between two adjacent cold fans, further improving the installation stability of the buckle device 10.

[0037] For further information, see Figure 1 In one embodiment, the buckle body 110 is provided with a middle column 113 at the position of two adjacent reinforcing protrusions 130, and the middle column 113 is provided with a threaded hole 1131. It should be noted that the existence of the middle column 113 not only enhances the structural rigidity of the buckle device 10, but also the middle column 113 is installed on the buckle body 110 by threaded installation through the threaded hole 1131 (a through hole is provided on the buckle body 110 at the position corresponding to the threaded hole 1131).

[0038] For further information, see Figure 1In one embodiment, the buckle body 110 is provided with chamfered portions 114 at both sides. It should be noted that the design of the chamfered portions 114 at both sides of the buckle body 110 greatly optimizes the installation process, reduces the friction resistance and stress concentration during the installation process, and enables the buckle device 10 to be more smoothly and smoothly docked with the cooling fan, thereby improving the installation efficiency and quality. At the same time, the design of the chamfered portions 114 can also make the structure of the buckle device 10 more compact.

[0039] Figure 2 Shown is a schematic structural diagram of a heat dissipation module 20 in an embodiment of the present application.

[0040] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A heat dissipation module 20 includes several of the above-mentioned snap-in devices 10, and also includes several cold fans 30, each of which is provided with a snap-in hole (not shown in the figure), and each of the cold fans 30 is provided with several probes (not shown in the figure), wherein the two elastic snap-in arms 121 can be deformed toward each other under the action of external force, so that the snap-in protrusions 1211 located at the end can be snapped into the snap-in holes one by one, and then the probes can contact the contact foil points one by one, thereby realizing the series connection of the cold fans 30.

[0041] The technical solution of the present application is to deform the two elastic snap arms 121 towards each other under the action of external force, so that each snap protrusion 1211 at the end can be snapped into the snap hole of the cold fan 30 one by one, and then each probe can contact each contact foil point one by one, so as to realize the series connection of the cold fan 30. The series connection operation mode is simple and convenient, and the test line of the cold fan 30 is omitted, which effectively avoids the difficulty of wiring the client due to too many internal test lines, and also improves the internal heat dissipation efficiency of the heat dissipation module 20. This series connection mode not only simplifies the traditional complex layout of independent test lines, but also greatly improves the neatness of the inside of the heat dissipation module, reduces the influence of cables on airflow, and thus improves the heat dissipation efficiency. At the same time, the connection mode realized in series by the snap device 10 not only simplifies the traditional complex layout of independent test lines, but also greatly improves the neatness of the inside of the heat dissipation module 20, reduces the influence of cables on airflow, and thus improves the heat dissipation efficiency.

[0042] It should also be noted that the number of contact foil points and probes is the same, and the number of contact foil points and probes can be flexibly configured according to actual needs, and the specific number is not specifically limited in this embodiment.

[0043] In addition, when assembling the heat dissipation module 20, in order to test each cold fan 30, after multiple cold fans 30 are assembled in series using the snap-fit ​​device 10, the cold fan 30 located at the head (the head, i.e., the first cold fan 30) needs to be connected to a test line, and all test signals are transmitted to the following cold fans 30 through the test line of the head cold fan 30. The test line can also be connected to the head cold fan 30 using the snap-fit ​​device 10 as in the present embodiment, such as Figure 2 , Figure 3 and Figure 4 The buckle device with the test line 40 is shown. The structure and the buckle device with the test line 40 are the same and the buckle connection principle is not repeated here.

[0044] For further information, see Figure 2 , Figure 3 and Figure 4 In one embodiment, each cold fan 30 includes: a wind shell 310, a fan blade (not shown) and a motor (not shown), each buckle hole and each probe are located on the wind shell 310, the fan blade is installed in the wind shell 310, and the fan blade 320 can rotate relative to the wind shell 310, and the motor is installed in the wind shell 310, and is connected to the drive shaft and the fan blade of the motor. It should be noted that the cold fan 30 includes three major parts: the wind shell 310, the fan blade and the motor, and the buckle hole and the probe position pre-opened on the wind shell 310 form a precise docking with the buckle device 10. When the buckle convex of the buckle device 10 is embedded in the buckle hole and the probe contacts the contact foil point, the series connection between the cold fans 30 and the cold fans 30 is completed.
