[0027] In the related art, in order to ensure the working status of the cooling fan, each cooling fan is equipped with an independent test line. However, when multiple cooling fans are tightly integrated into the same air cooling module, the independent test lines will cause a series of problems. For example, multiple test lines will increase the difficulty of wiring, and the interlacing and entanglement between the test lines will affect the neatness of 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 magnetic suction device and an air-cooling module, which can eliminate the test line of the cold fan, reduce the difficulty of wiring, and at the same time improve the heat dissipation efficiency of the air-cooling module.

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

[0030] See also Figure 1 A magnetic device 10 includes a carrier 100 and a magnetic kit 200. It should be noted that the carrier serves as the basic structure of the magnetic device 10 and carries various structural components of the magnetic device 10. The magnetic kit 200 serves to install the magnetic device 10 on the air cooling module.

[0031] See also Figure 1 The carrier 100 is provided with a guide plate 110, and the guide plate 110 is provided with a plurality of contact copper foil points at both sides (not shown in the figure). It should be noted that the guide plate 110 plays the role of a "middle bridge", electrically connecting the contact copper foil points at both sides, and the contact copper foil points provided on both sides undertake the task of current conduction, and are a bridge to realize the series operation of multiple cooling fans 300.

[0032] See also Figure 1 The magnetic attraction kit 200 includes two magnetic attraction pairs 210, which are axially symmetrically distributed with respect to the central axis of the carrier 100. The magnetic attraction pairs 210 include more than one magnet 211, and the magnet 211 is disposed on the carrier 100. It should be noted that the two magnetic attraction pairs 210 in the magnetic attraction kit 200, with their unique axially symmetrical layout, ensure that they can be quickly and accurately adsorbed into place when docking with the cooling fan 300 in the air cooling module.

[0033] For further information, see Figure 1In one embodiment, the carrier 110 includes a back cover 120 and a front cover 130. The front cover 130 is disposed on the back cover 120. The inner walls of the front cover 130 and the back cover 120 together form a cavity (not shown in the figure). The guide plate 110 and the two magnetic pairs 210 are both disposed in the cavity. The front cover 130 is provided with a transparent window 131 at the position corresponding to the two contact points of the copper foil. It should be noted that the carrier 100 is composed of the back cover 120 and the front cover 130. The front cover 130 is disposed on the back cover 120 in a covering form. The inner walls of the two are tightly combined to form a closed cavity structure. The main function of this cavity design is to accommodate and protect the key components inside, such as the guide plate 110 and the magnetic pair 210, from interference from external factors, and it also helps to maintain the overall stability of the device.

[0034] It should also be noted that the front cover 130 is specially provided with a transparent window 131 structure at the position corresponding to the contact copper foil point. The purpose of this design is to allow external equipment (such as a probe on a cooling fan) to directly contact the contact copper foil point in the carrier 100 through the transparent window 131, so as to achieve electrical connection without destroying the overall sealing. The design of the transparent window 131 avoids unnecessary openings, enhances the waterproof and dustproof capabilities of the device, and ensures the reliability and durability of the electrical contact.

[0035] For further information, see Figure 1 In one embodiment, the front cover 130 is provided with receiving grooves 132 at both sides of the transparent window 131, and the magnets 211 are arranged in the receiving grooves 132 one by one. It should be noted that the magnets 211 are cleverly installed on the carrier 100, especially in the receiving grooves 132 specially opened on the front cover 130, which not only ensures the stable installation of the magnets 211, but also maximizes the utilization effect of the magnetic attraction force to achieve efficient lossless connection. The design of the receiving grooves 132 can also improve the compactness of the structure of the magnetic attraction device 10 and reduce the volume of the magnetic attraction device 10.

[0036] For further information, see Figure 1 In one embodiment, the rear cover 120 is provided with two gripping protrusions 121, and the two gripping protrusions 121 are axially symmetrically distributed about the central axis of the rear cover 120. It should be noted that the gripping protrusions 121 of the rear cover 120 provide an easy-to-operate structure, which is convenient for operators to disassemble and assemble the magnetic device 10.

[0037] For further information, see Figure 1 In one embodiment, the rear cover 120 is provided with a chamfer 122 at a corner position. It should be noted that the design of the chamfer 122 can further improve the compactness of the structure of the magnetic device 10, and also make it easier for the front cover 130 to be covered on the rear cover 120.

[0038] For further information, see Figure 1In one embodiment, the front cover 130 has rounded corners 133 at the corners. It should be noted that the design of the rounded corners 133 can further improve the compactness of the magnetic device 10 and also make it easier for the front cover 130 to be covered on the rear cover 120.

[0039] Furthermore, in one embodiment, the front cover 130 is provided with a convex column (not shown). It should be noted that the presence of the convex column can enhance the structural rigidity of the magnetic device 10. More importantly, the convex columns on both sides can make the magnetic device 10 contact with the wind shell of the cold fan 300 when installed on the cold fan 300, so that the magnetic device 10 can be more stably reinforced between two adjacent cold fans 300, further improving the installation stability of the magnetic device 10.

[0040] Furthermore, in one embodiment, the front cover 130 is provided with two reinforcing protrusions (not shown), and the two reinforcing protrusions are axially symmetrically distributed about the central axis of the convex column. The reinforcing protrusions increase the overall strength and deformation resistance of the magnetic suction device 10. In other embodiments, the two reinforcing protrusions 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 protrusions on both sides enable the magnetic suction device 10 to be installed on the cold fan 300. Contact with the wind shell of the cold fan 300, so that the magnetic suction device 10 can be more stably reinforced between two adjacent cold fans 300, further improving the installation stability of the magnetic suction device 10.

[0041] See also Figure 2 , Figure 3 and Figure 4 A wind cooling module 20 includes a plurality of magnetic devices 10 as described above, and a plurality of cold fans 300. The cold fans 300 are each provided with a magnetic matching pair 310. The magnetic matching pair 310 includes one or more magnetic matching bodies 311, and each cold fan 300 is provided with a plurality of probes 320. When the magnetic device 10 is installed on two adjacent cold fans 300, each magnet 211 is adsorbed on each magnetic matching body 311 one by one, so that each probe 320 contacts each contact foil point one by one, thereby realizing the series connection of the cold fans 300.

[0042] Furthermore, the magnetically attracted matching body 311 may be an iron block, or a magnet with a polarity opposite to that of the corresponding magnet 211 .

[0043] In this embodiment, the magnetically attracted matching body 311 is a magnet with opposite polarity to the corresponding magnet 211 , and the magnets attract each other to achieve mutual calibration and positioning, and improve the stability of the magnetically attracted device 10 .

[0044] According to the technical solution of the present application, when the magnetic attraction device 10 is installed on two adjacent cooling fans 300, each magnet 211 is adsorbed on each magnetic attraction fitting body 311 one by one, so that each probe 320 is in contact with each contact foil point one by one, thereby realizing the series connection of the cooling fans 300. The series connection operation is simple and convenient, eliminating the test line of the cooling fan 300, effectively avoiding the increased difficulty of wiring on the client side due to too many internal test lines, and also improving the internal heat dissipation efficiency of the air-cooled module 300.

[0045] It should also be noted that the number of the contact foil points and the number of the probes 320 are the same, and the number of the contact foil points and the number of the probes 320 can be flexibly configured according to actual needs, and the specific number is not specifically limited in this embodiment.

[0046] In addition, when assembling the air-cooling module 20, in order to test each cooling fan 300, after multiple cooling fans 300 are assembled in series using the magnetic suction device 10, the cooling fan 30 located at the head (the head, i.e., the first cooling fan 300) needs to be connected to a test line, and all test signals are transmitted to the cooling fans 300 behind through the test line of the cooling fan 300 at the head. The test line can also be connected to the cooling fan 300 at the head using the magnetic suction device 10 as in the present embodiment, such as Figure 2 , Figure 3 and Figure 4 What is shown is a snap-on device with a test line 40 and a magnetic device with a test line 40 . The structure and magnetic principle are the same and will not be described again here.

[0047] For further information, see Figure 3 and Figure 4 In one embodiment, each cooling fan 300 includes: a wind housing 330, a fan blade (not shown) and a motor (not shown), each magnetic attraction fitting body 311 and each probe 320 are located on the wind housing 330, the fan blade is installed in the wind housing 330, and the fan blade can rotate relative to the wind housing 330, the motor is installed in the wind housing 330, and is connected to the drive shaft and the fan blade of the motor. It should be noted that the cooling fan 300 includes three major parts: the wind housing 330, the fan blade and the motor. The magnetic attraction fitting body 311 and the probe 320 pre-installed on the wind housing 310 form a precise docking with the magnetic attraction device 10. When the magnetic attraction device 10 is installed on the air-cooling module 20, when the probe 320 contacts the contact foil point, the series connection between the cooling fans 300 and the cooling fans 300 is completed.
