Description

Technical Field

[0001] This application relates to the field of heat dissipation technology, and in particular to a cooling fan mounting structure. Background Technology

[0002] Low-frequency transformers are used to transmit signal voltage and signal power, and can also achieve impedance matching between circuits. They also provide isolation for DC power. The equipment generates a lot of heat during use and requires heat dissipation.

[0003] In traditional solutions, such as Figure 1 As shown, fans are often used for heat dissipation. The fans are mounted on the mounting plate with bolts, and the mounting plate is fixed to the equipment casing. The heat sink is set on one side of the fan and is cooled by the fan.

[0004] In the above solution, the fan is fastened with bolts. The bolts protrude on both sides of the fan, making it difficult for the fan to fit snugly against the heatsink. This causes the fan speed to become turbulent and greatly reduces the fan's cooling effect. Utility Model Content

[0005] The main purpose of this application is to provide a cooling fan mounting structure that aims to solve the problems of disordered fan speed and poor heat dissipation in traditional heat dissipation solutions.

[0006] To achieve the above objectives, this application provides a cooling fan mounting structure for mounting a cooling fan. The mounting structure includes a mounting plate, at least two first limiting posts, a panel, at least two second limiting posts, and a cooling fan. The mounting plate has an air inlet. At least two first limiting posts are fixed to one side of the mounting plate and located around the air inlet. The panel is parallel to the mounting plate and sleeved around the outer periphery of the first limiting posts. The panel has the freedom to move axially along the first limiting posts. The panel has ventilation holes that are opposite to the air inlet in a first direction, which is perpendicular to the mounting plate. At least two second limiting posts are correspondingly disposed around the ventilation holes. The cooling fan is fitted onto the side of the panel facing the mounting plate and located between the ventilation holes and the air inlet. The cooling fan has multiple mounting holes, and the second limiting posts are inserted into these mounting holes.

[0007] Optionally, the panel includes a main board, a vertical plate, and a positioning plate. The main board is parallel to the mounting plate and has ventilation holes. The vertical plate corresponds to the first limiting post and is fixed to the outer periphery of the main board. The positioning plate is fixed to the end of the vertical plate away from the main board. The positioning plate has positioning holes, and the first limiting post passes through the corresponding positioning holes. In the first direction, the positioning plate is located between the main board and the mounting plate.

[0008] Optionally, the vertical plate is perpendicular to the main board, and the positioning plate is parallel to the main board.

[0009] Optionally, in the first direction, the minimum distance between the positioning plate and the mounting plate is a, and the minimum distance between the cooling fan and the mounting plate is b, where a ≤ b.

[0010] Optionally, the axial direction of the second limiting post is the same as that of the first direction.

[0011] Optionally, the axial direction of the first limiting post is the same as the first direction.

[0012] Optionally, the plane perpendicular to the plane where the mounting plate is located is denoted as the first plane, the axis of the first limiting post is parallel to the first plane, and the included angle between the first limiting post and the mounting plate is c, where 30°≤c≤60°.

[0013] Optionally, the included angle c between the first limiting post and the mounting plate is 45°.

[0014] Optionally, there are multiple cooling fans, all distributed on the side of the panel facing the mounting plate; wherein, the ventilation holes correspond one-to-one with the cooling fans, and at least two second limiting posts are distributed around the periphery of each ventilation hole.

[0015] Optionally, the area where the air inlet is located on the mounting plate is the air intake area; the orthographic projection of each of the ventilation holes on the mounting plate is located within the air intake area.

[0016] The cooling fan mounting structure proposed in this application embodiment allows the mounting plate to be part of the equipment casing, with the air inlet being the air intake area on the equipment casing. In use, the cooling fan is attached to the panel, allowing the second limiting post to be inserted into the mounting hole. Then, the panel is fitted onto the first limiting post, thus initially defining the relative position between the cooling fan and the equipment casing. Afterward, the component to be cooled is placed against the side of the panel away from the cooling fan to dissipate heat. At this point, the position of the cooling fan is completely fixed, and the side of the panel away from the cooling fan has no other structure, allowing it to completely fit the component to be cooled, effectively improving the heat dissipation effect. At the same time, the limiting post structure makes installing the cooling fan more convenient and faster than using bolts. Attached Figure Description

[0029] refer to Figures 1-6 It should be understood that Figure 3 The connections between the various components should be like Figure 2 As compact as in the middle, Figure 5 The connections between the various components should be like Figure 4 As compact as in the middle, this is only for illustrative purposes and will Figure 3 and Figure 5 The components are shown disassembled for easier understanding. This application provides a cooling fan mounting structure for mounting a cooling fan 4. The cooling fan mounting structure may include a mounting plate 1, at least two first limiting posts 5, a panel 2, at least two second limiting posts 3, and a cooling fan 4. The mounting plate 1 has an air inlet 11. At least two first limiting posts 5 are fixed to one side of the mounting plate 1 and located around the air inlet 11. The panel 2 is parallel to the mounting plate 1 and sleeved around the outer periphery of the first limiting posts 5. The panel 2 has the freedom to move along the axial direction of the first limiting posts 5. The panel 2 is provided with ventilation holes 211, which are opposite to the air inlet 11 in a first direction, which is perpendicular to the mounting plate 1. At least two second limiting posts 3 are correspondingly arranged around the ventilation holes 211. The cooling fan 4 is fitted onto the side of the panel 2 facing the mounting plate 1 and located between the ventilation holes 211 and the air inlet 11. The cooling fan 4 has multiple mounting holes 41, and the second limiting posts 3 are inserted into the mounting holes 41.

[0030] The cooling fan mounting structure proposed in this application embodiment can be part of the equipment shell, and the air inlet 11 is the air intake area on the equipment shell. In use, the cooling fan 4 is attached to the panel 2, so that the second limiting post 3 is inserted into the mounting hole 41, and then the panel 2 is sleeved on the first limiting post 5. In this way, the relative position of the cooling fan 4 and the equipment shell can be initially defined. Then, the heat dissipation component 6 is placed against the side of the panel 2 away from the cooling fan 4 to dissipate heat. At this time, the position of the cooling fan 4 is completely fixed. There is no other structure on the side of the panel 2 away from the cooling fan 4, so it can be completely attached to the heat dissipation component 6, which can effectively improve the heat dissipation effect. At the same time, the installation of the cooling fan 4 by the limiting post structure is more convenient and faster than the installation by bolts.

[0031] When the mounting plate 1 is part of the equipment housing, the heat dissipation component 6 is installed inside the equipment housing, that is, the relative position of the heat dissipation component 6 and the mounting plate 1 is fixed. Therefore, the panel 2 and the cooling fan 4 can be pressed and limited by the heat dissipation component 6.

[0032] When the device is a low-frequency transformer, the mounting plate 1 is part of the low-frequency transformer housing, the heat dissipation component 6 is the heat sink inside the low-frequency transformer, and the panel 2, the second limiting post 3, the cooling fan 4 and the first limiting post 5 are all located inside the housing.

[0033] It should be understood that the airflow is drawn into the casing from the air inlet 11 by the cooling fan 4 and blown out from the ventilation hole 211 to the heat-dissipating component 6.

[0034] refer to Figure 2 and Figure 3 In an exemplary embodiment, the panel 2 may include a main board 21, a vertical plate 22, and a positioning plate 23. The main board 21 is parallel to the mounting plate 1 and is provided with ventilation holes 211. The vertical plate 22 corresponds one-to-one with the first limiting post 5 and is fixed to the outer periphery of the main board 21. The positioning plate 23 is fixed one-to-one with the end of the vertical plate 22 away from the main board 21. The positioning plate 23 is provided with positioning holes 231, and the first limiting post 5 passes through the corresponding positioning hole 231. In the first direction, the positioning plate 23 is located between the main board 21 and the mounting plate 1.

[0035] The first limiting post 5 passes through the positioning hole 231 on the positioning plate 23, so that the positioning plate 23 can move along the axial direction of the first limiting post 5, that is, the main board 21 can be disassembled or installed by moving along the axial direction of the first limiting post 5.

[0036] Specifically, there can be four first limiting posts 5, and thus four positioning plates 23. The four positioning plates 23 are respectively set at the four corners of the main board 21. In this way, the four first limiting posts 5 and the four positioning plates 23 work together to achieve a better limiting effect on the panel 2.

[0037] In addition, the second limiting post 3 corresponding to the ventilation hole 211 can also have four surrounding the outer periphery of the ventilation hole 211. The common cooling fan 4 on the market also has four mounting holes 41 on its outer periphery. In this way, after the second limiting post 3 is inserted into the mounting hole 41, the limiting effect on the cooling fan 4 is better.

[0038] In the thickness direction of the vertical plate 22, the positioning plate 23 is located on the side of the vertical plate 22 away from the main plate 21, so as to prevent the first limiting post 5 from interfering with the vertical plate 22.

[0039] refer to Figure 2 In an exemplary embodiment, the vertical plate 22 is perpendicular to the main board 21, and the positioning plate 23 is parallel to the main board 21.

[0040] In an exemplary embodiment, in the first direction, the minimum distance between the positioning plate 23 and the mounting plate 1 is a, and the minimum distance between the cooling fan 4 and the mounting plate 1 is b, and a≤b.

[0041] If a≤b, when the heat sink 6 touches the panel 2, it will push the panel 2 and the mounting plate 1 to clamp the cooling fan 4. This will have a better limiting effect on the cooling fan 4 and will hardly cause any shaking.

[0042] In an exemplary embodiment, the axial direction of the second limiting post 3 is the same as that of the first direction, and the axial direction of the first limiting post 5 is the same as that of the first direction.

[0043] Thus, when installing the cooling fan 4, simply move the cooling fan 4 along the first direction so that the second limiting post 3 is inserted into the mounting hole 41, which is convenient and quick. Similarly, when installing the panel 2, simply move the panel 2 along the first direction so that the first limiting post 5 is inserted into the positioning hole 231, which is also convenient and quick.

[0044] In an exemplary embodiment, the plane perpendicular to the plane where the mounting plate 1 is located is denoted as the first plane, the axis of the first limiting post 5 is parallel to the first plane, and the included angle between the first limiting post 5 and the mounting plate 1 is c, and 30°≤c≤60°.

[0045] If 30°≤c≤60°, during use, the end of the first limiting post 5 away from the mounting plate 1 should face upwards. In this way, when the panel 2 is fitted onto the first limiting post 5, the panel 2 will always have a downward tendency due to its own weight and the weight of the cooling fan 4. That is, the panel 2 will always have a tendency to move closer to the mounting plate 1 along the axis of the first limiting post 5, thereby preventing the panel 2 from detaching from the first limiting post 5.

[0046] At this point, heat dissipation can begin once the heat sink 6 is in contact with the panel 2. There is no need to squeeze the panel 2; the panel 2 can automatically clamp the cooling fan 4 with the mounting plate 1.

[0047] The larger the value of c, the more difficult it is to operate the mounting panel 2, and the easier it is for the first limiting post 5 and the vertical plate 22 to interfere, but the better the limiting effect on the cooling fan 4. The smaller the value of c, the easier it is to operate the mounting panel 2, and the less likely the first limiting post 5 and the vertical plate 22 are to interfere, but the worse the limiting effect on the cooling fan 4. In the preferred embodiment, the included angle c between the first limiting post 5 and the mounting plate 1 is 45°, so the operation of the mounting panel 2 is relatively easy, the first limiting post 5 and the vertical plate 22 are less likely to interfere, and the limiting effect on the cooling fan 4 is better.

[0048] refer to Figure 2 In an exemplary embodiment, there are multiple cooling fans 4, all distributed on the side of the panel 2 facing the mounting plate 1; wherein, ventilation holes 211 are distributed one-to-one with cooling fans 4, and at least two second limiting posts 3 are distributed around each ventilation hole 211.

[0049] Among them, such as Figure 2 As shown, there are two cooling fans 4. This is only one implementation method. There can also be three, four, five, etc., and multiple cooling fans 4 can be arranged in an array on the side of the motherboard 21 facing the mounting plate 1, such as a rectangular array or a circular array, etc.

[0050] refer to Figure 3 In an exemplary embodiment, the area where the air inlet 11 is located on the mounting plate 1 is the air intake area, and the orthographic projection of each ventilation hole 211 on the mounting plate 1 is located within the air intake area.

[0051] In this configuration, the orthographic projection of each ventilation hole 211 on the mounting plate 1 is located within the air intake area, and the cooling fan 4 is located between the ventilation hole 211 and the air intake area, thus ensuring the air intake requirements of each cooling fan 4.

[0052] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
