Description

Technical Field

[0001] This utility model relates to the field of fans, specifically to a heat dissipation fan that is easy to connect. Background Technology

[0002] Cooling fans are designed for applications that use forced convection to quickly remove heat. They are widely applicable to various devices with strict requirements for temperature control of core components, including CPU and graphics card cooling in computer hosts, server rack cluster cooling in data centers, thermal management systems for electronic control units and power battery packs in new energy vehicles, and high-power electrical equipment such as high-frequency inverters and servo drives in industrial production. They are also suitable for base station equipment in communication base stations, medical diagnostic instruments, and electronic equipment in rail transit vehicles, where high stability in heat dissipation and ease of maintenance are required.

[0003] Existing cooling fans lack a structure that allows for quick pre-positioning without tools when connecting units. They typically require screws and other fasteners and tools for installation, which not only increases the complexity of the installation process but also makes disassembly difficult during subsequent maintenance, significantly reducing the overall efficiency of installation and maintenance. At the same time, when multiple cooling fans are used in parallel, there is a lack of components that can secure them into a unified whole to enhance structural stability, and independent power supply control methods make it difficult to achieve synchronous operation of the fan group, further reducing the overall cooling efficiency. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide a conveniently connected cooling fan. The annular magnetic ring at the rear end of the male connector surface and the mating magnetic ring at the rear end of the female connector groove have opposite polarities, which can generate a magnetic attraction effect, enabling rapid pre-positioning between the various units of the cooling fan. This solves the technical problem that the existing technology not only increases the complexity of installation operations but also leads to difficulties in disassembly during subsequent maintenance, significantly reducing the overall efficiency of installation and maintenance.

[0005] The objective of this utility model is achieved through the following means:

[0006] A conveniently connected cooling fan includes a front half-shell and a rear half-shell. The front half-shell is located on the front of the rear half-shell, and a fan section is added between the front and rear half-shells. Male connectors are installed at the four corners of the front of the front half-shell, and female connector slots are opened at the four corners of the front of the rear half-shell. The male connectors are generally convex, and the female connector slots are generally concave. An annular magnetic ring is fitted onto the rear end of the surface of the male connector, and a mating magnetic ring is installed at the rear end of the inner cavity of the female connector slot. The annular magnetic ring and the mating magnetic ring have opposite polarities. Conductive contacts are installed on the end face of the male connector in a ring-shaped arrangement. An elastic contact terminal is added to the rear end of the inner cavity of the female connector slot in a ring-shaped arrangement. The positions of the conductive contacts and the elastic contact terminals correspond. Fixing holes are opened at the upper and lower centers of the front of both the front and rear half-shells, and bolts are installed inside the fixing holes. Fixing side plates are installed at the center of both sides between the front and rear half-shells, and storage slots are opened on the front and back of the fixing side plates.

[0007] Align the male connectors at the four corners of the front half of the housing of one cooling fan with the female connector slots at the four corners of the front half of the housing of another cooling fan; through the magnetic attraction of the annular magnetic ring and the matching magnetic ring, the two or more fans can be quickly pre-connected, and at the same time, the conductive contacts of the male connector of the first fan can reliably contact the elastic contact terminals of the female connector slot of the second fan, so as to complete the power and control signal transmission between multiple fans and achieve electrical synchronization.

[0008] Insert bolts into the fixing holes at the center of the upper and lower front sides of the front half of all pre-connected fans, as well as the fixing holes at the center of the upper and lower front sides of the rear half of the fans, and tighten the bolts to form a rigid whole from multiple parallel, easily connected cooling fans.

[0009] The external connection cables are coiled into the storage slots on the front and back of the fixed side panel and secured to prevent them from becoming tangled. This completes the expansion and overall assembly of multiple easily connected cooling fans.

[0010] Furthermore, a fixing rod is connected between the front half shell and the rear half shell, and the fixing rod is located at the four corners between the front half shell and the rear half shell.

[0011] By setting fixing rods at the four corners to connect the front and rear shells, the front and rear shells can be fixed from multiple stress points, which enhances the stability and firmness of the connection between the front and rear shells and improves the overall structure's resistance to deformation.

[0012] Furthermore, a take-up roller is rotatably connected to the center of the inner cavity of the storage groove, and a gear is coaxially connected to the top of the take-up roller. The two sides of the gear extend outward through the inner wall of the storage groove.

[0013] The take-up roller can rotate within the take-up slot, facilitating the winding or unwinding of external cables. The gear is coaxially connected to the take-up roller and extends outside the take-up slot, allowing the gear to be driven to rotate via an external structure, thereby controlling the movement of the take-up roller and improving operational convenience.

[0014] Furthermore, a fixing rod is slidably connected to the upper center of the outer side of the fixing side plate, and the surface of the fixing rod is tightly fitted with the corresponding tooth groove on the gear.

[0015] The tight fit between the fixing rod and the gear tooth groove restricts the rotation of the gear, thereby fixing the position of the take-up roller and preventing accidental rotation of the take-up roller when not in operation, thus ensuring the stability of the winding or unwinding state.

[0016] Furthermore, a positioning groove is provided in the upper part of the inner cavity of the fixed side plate, and a positioning block is slidably connected to the upper part of the inner cavity of the positioning groove. The outer side of the positioning block extends outward through the inner wall of the positioning groove and connects to the bottom end of the fixed insertion rod.

[0017] The positioning groove provides a guiding path for the sliding of the positioning block, ensuring that the positioning block can slide stably, thereby ensuring the accurate sliding trajectory of the fixed rod, enabling the fixed rod to precisely engage with the tooth groove on the gear, and improving the fit accuracy between the structures.

[0018] Furthermore, a compression spring is added to the center of the inner cavity of the positioning groove, and the top and bottom ends of the compression spring are respectively attached to the lower surface of the positioning block and the bottom of the inner cavity of the positioning groove.

[0019] The elastic force of the compression spring can continuously act on the positioning block, ensuring that the fixing rod is always tightly engaged with the gear tooth groove. This enhances the fixing effect of the fixing rod on the gear, prevents the fixing rod from detaching from the gear due to vibration or other factors, and further improves the stability of the structure.

[0020] The beneficial effects of this utility model are:

[0021] By engaging the male connector of the front half-shell with the female connector of the rear half-shell, and with the annular magnetic ring at the rear end of the male connector surface and the matching magnetic ring at the rear end of the female connector cavity having opposite polarities, a magnetic attraction effect can be generated, enabling rapid pre-positioning between the various units of the cooling fan. This ensures a tight fit between the male connector and the female connector, while also allowing reliable contact between the annularly distributed conductive contacts on the end face of the male connector and the correspondingly distributed elastic contact terminals at the rear end of the female connector cavity. The entire assembly process can be completed by hand without the aid of tools, greatly improving the installation efficiency of the cooling fan and the ease of disassembly during subsequent maintenance.

[0022] The conductive contacts of the male connector cooperate with the elastic contact terminals of the female connector slot to stably transmit power and control signals, allowing multiple cooling fans to share a single power interface and control signal. This avoids the problem of difficulty in achieving synchronous operation when using independent power supply control and ensures the synchronicity of the cooling fan group's operation.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The specific implementation of a conveniently connected cooling fan includes a front half-shell 1 and a rear half-shell 2. The front half-shell 1 is located on the front of the rear half-shell 2. A fan part 3 is added between the front half-shell 1 and the rear half-shell 2. Male connectors 4 are installed at the four corners of the front of the front half-shell 1, and female connector grooves 5 are opened at the four corners of the front of the rear half-shell 2. The male connectors 4 are generally convex in design, and the female connector grooves 5 are generally concave in design. An annular magnetic ring 6 is fitted on the rear end of the surface of the male connector 4, and a mating magnetic ring 8 is installed on the rear end of the inner cavity of the female connector groove 5. The annular magnetic ring 6 and the mating magnetic ring 8 are connected. The male connector 4 has conductive contacts 7 installed on its end face, which are arranged in a ring. The female connector 5 has elastic contact terminals 9 installed at the rear end of its inner cavity, which are also arranged in a ring. The positions of the conductive contacts 7 and the elastic contact terminals 9 are corresponding. The front half shell 1 and the rear half shell 2 have fixing holes at the center of the upper and lower parts of their front surfaces. The inner cavity of the fixing holes is fitted with bolts 10. Fixing side plates 11 are installed at the center of both sides between the front half shell 1 and the rear half shell 2. The front and back of the fixing side plates 11 have storage grooves 12.

[0032] Align the male connectors 4 at the four corners of the front half shell 1 of one cooling fan with the female connector slots 5 at the four corners of the front half shell 2 of another cooling fan; through the magnetic attraction of the annular magnetic ring 6 and the matching magnetic ring 8, the two or more fans are quickly pre-connected, and at the same time, the conductive contacts 7 of the male connector 4 of the first fan and the elastic contact terminals 9 of the female connector slot 5 of the second fan are reliably contacted, so as to complete the power and control signal transmission between multiple fans and achieve electrical synchronization.

[0033] Insert bolts 10 into the fixing holes at the center of the upper and lower front of the front half shell 1 and the center of the upper and lower front of the rear half shell 2 of all the pre-connected fans, and tighten the bolts 10 to form a rigid whole by connecting multiple parallel cooling fans.

[0034] The external connection cables are coiled in the storage slots 12 opened on the front and back of the fixed side plate 11 and the cables are fixed to avoid tangling. This completes the expansion and overall assembly of multiple conveniently connected cooling fans.

[0035] By utilizing the opposite polarity of the annular magnetic ring 6 on the male connector 4 and the mating magnetic ring 8 in the female connector groove 5, rapid pre-positioning can be achieved for both the docking of the front half shell 1 and the rear half shell 2 of a single fan and the extended docking between multiple fans, allowing for initial assembly without the need for additional tools. At the same time, the annularly distributed conductive contacts 7 and the elastic contact terminals 9 can precisely dock with the magnetic attraction, ensuring the reliability of the electrical connection, greatly reducing the difficulty of installation, and providing convenience for the subsequent disassembly and maintenance of the fan.

[0036] By inserting bolts 10 into the fixing holes at the top and bottom centers of the front half shell 1 and the rear half shell 2, multiple parallel fans can be fastened into a rigid whole, effectively resisting the vibration generated during the operation of the fans and preventing the connection between the fans from loosening. In addition, the fixing side plates 11 at the center of both sides between the front half shell 1 and the rear half shell 2 can strengthen the structural strength of a single fan and prevent the fan part 3 from shifting. The double mechanical protection can significantly reduce the noise during the operation of the fans and improve the overall operational reliability.

[0037] The circularly distributed and corresponding conductive contacts 7 and elastic contact terminals 9 can stably transmit power and control signals, allowing multiple fans to share a single power interface and control signal. This solves the problem of poor synchronization caused by traditional independent power supply control and ensures heat dissipation efficiency. The storage slots 12 on the front and back of the fixed side plate 11 can centrally coil and fix external cables, avoiding multiple cables from being tangled and reducing obstruction of the internal air duct of the equipment, while also improving the cleanliness of the equipment's interior.

[0038] like Figure 2 As shown, a fixing rod 19 is connected between the front half shell 1 and the rear half shell 2, and the fixing rod 19 is located at the four corners between the front half shell 1 and the rear half shell 2.

[0039] When the front half shell 1 and the rear half shell 2 are connected, the connection between the two is achieved by fixing rods 19. The fixing rods 19 are respectively set at the four corners between the front half shell 1 and the rear half shell 2 to complete the assembly of the front half shell 1 and the rear half shell 2. By setting fixing rods 19 at the four corners to connect the front half shell 1 and the rear half shell 2, the front half shell 1 and the rear half shell 2 can be fixed from multiple force points, which enhances the stability and firmness of the connection between the front half shell 1 and the rear half shell 2 and improves the deformation resistance of the overall structure.

[0040] like Figure 5 As shown, a take-up roller 13 is rotatably connected to the center of the inner cavity of the storage groove 12, and a gear 14 is coaxially connected to the top of the take-up roller 13. The two sides of the gear 14 extend outward through the inner wall of the storage groove 12.

[0041] A take-up roller 13 is installed at the center of the inner cavity of the storage slot 12. The take-up roller 13 can rotate at the center of the inner cavity of the storage slot 12. The top end of the take-up roller 13 is coaxially connected to the gear 14, so that when the take-up roller 13 rotates, it can drive the gear 14 to rotate synchronously. The two sides of the gear 14 extend outward through the inner wall of the storage slot 12. The take-up roller 13 can rotate inside the storage slot 12, which is convenient for winding or unwinding external cables. The gear 14 is coaxially connected to the take-up roller 13 and extends to the outside of the storage slot 12, which is convenient for driving the gear 14 to rotate through the external structure, thereby controlling the movement of the take-up roller 13 and improving the convenience of operation.

[0042] like Figure 6As shown, a fixed insert rod 15 is slidably connected to the upper center of the outer side of the fixed side plate 11, and the surface of the fixed insert rod 15 is tightly fitted with the corresponding tooth groove on the gear 14.

[0043] The fixing rod 15 is connected to the upper center of the outer side of the fixing side plate 11 and can slide along the fixing side plate 11. When the fixing rod 15 slides to the corresponding position, its surface is tightly fitted with the corresponding tooth groove on the gear 14. The tight fit between the fixing rod 15 and the tooth groove of the gear 14 can limit the rotation of the gear 14, thereby fixing the position of the take-up roller 13 and preventing the take-up roller 13 from rotating unexpectedly in the non-operational state, thus ensuring the stability of the winding or unwinding state.

[0044] A positioning groove 18 is provided in the upper part of the inner cavity of the fixed side plate 11. A positioning block 16 is slidably connected to the upper part of the inner cavity of the positioning groove 18. The outer side of the positioning block 16 extends outward through the inner wall of the positioning groove 18 and connects to the bottom end of the fixed insertion rod 15.

[0045] A positioning groove 18 is provided in the upper part of the inner cavity of the fixed side plate 11. The positioning block 16 is installed in the upper part of the inner cavity of the positioning groove 18 and can slide along the inner cavity of the positioning groove 18. The outer side of the positioning block 16 extends outward through the inner wall of the positioning groove 18 and is connected to the bottom end of the fixed rod 15, so that the fixed rod 15 can move synchronously when the positioning block 16 slides. The positioning groove 18 provides a guide path for the sliding of the positioning block 16, ensuring that the positioning block 16 can slide stably, thereby ensuring the accuracy of the sliding trajectory of the fixed rod 15, so that the fixed rod 15 can accurately engage with the tooth groove on the gear 14, improving the fit accuracy between the structures.

[0046] A compression spring 17 is provided in the center of the inner cavity of the positioning groove 18. The top and bottom ends of the compression spring 17 are respectively attached to the lower surface of the positioning block 16 and the bottom of the inner cavity of the positioning groove 18.

[0047] A compression spring 17 is located at the center of the inner cavity of the positioning groove 18. Its top end is in contact with the lower surface of the positioning block 16, and its bottom end is in contact with the bottom of the inner cavity of the positioning groove 18. Under the elastic force of the compression spring 17, the positioning block 16 is pushed upward, which drives the fixing rod 15 to maintain its contact with the tooth groove of the gear 14. The elastic force of the compression spring 17 can continuously act on the positioning block 16, so that the fixing rod 15 is always tightly in contact with the tooth groove of the gear 14, which enhances the fixing effect of the fixing rod 15 on the gear 14, avoids the fixing rod 15 from the gear 14 due to vibration and other factors, and further improves the stability of the structure.

[0048] In this embodiment, a convenient connection method for cooling fans is implemented: the male connectors 4 at the four corners of the front half shell 1 of one cooling fan are aligned with the female connector slots 5 at the four corners of the front half shell 2 of another cooling fan. The magnetic attraction force of the annular magnetic ring 6 and the matching magnetic ring 8 enables the rapid pre-connection of two or more fans. At the same time, the conductive contact 7 of the male connector 4 of the first fan and the elastic contact terminal 9 of the female connector slot 5 of the second fan are reliably contacted, completing the transmission of power and control signals between multiple fans to achieve electrical synchronization. Then, bolts 10 are inserted into the fixing holes at the center of the upper and lower parts of the front half shell 1 of all pre-connected fans and the fixing holes at the center of the upper and lower parts of the front half shell 2 of the second fan, and the bolts 10 are tightened to form a rigid whole by multiple parallel conveniently connected cooling fans.

[0049] The external connection cable is placed in the storage slots 12 on the front and back of the fixed side plate 11. If the cable length needs to be adjusted, the winding roller 13 connected to the center of the inner cavity of the storage slot 12 can be rotated. The winding roller 13 is driven to rotate by the gear 14 to wind or release the cable. After the cable is adjusted, the fixed plug 15, which is slidably connected to the center of the upper part of the outer side of the fixed side plate 11, slides under the action of the positioning block 16, which is slidably connected to the positioning slot 18 in the upper part of the inner cavity of the fixed side plate 11. This makes the surface of the fixed plug 15 fit tightly with the corresponding tooth groove on the gear 14. At the same time, the compression spring 17 added to the center of the inner cavity of the positioning slot 18 provides elasticity, so that the positioning block 16 keeps the fixed plug 15 in contact with the tooth groove of the gear 14, restricting the rotation of the gear 14 to fix the position of the winding roller 13 and prevent the cable from getting tangled. This completes the expansion and overall assembly of multiple conveniently connected cooling fans.

[0050] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
