Description

Technical Field

[0001] This application relates to the technical field of heat dissipation, and more particularly to a heat dissipation device and a server. Background Technology

[0002] With the rapid development of the digital economy, the demand for computing power is constantly increasing, and the power consumption of key chips such as CPUs and GPUs is rising rapidly. The power consumption of a single server has exceeded 3000W, especially for multi-processor servers with GPUs. Therefore, cooling devices are needed to dissipate heat from servers. Server air cooling typically uses a cooling fan to drive cool air in from the front panel, where it convects and exchanges heat with the internal components, and then the hot air is carried out from the rear panel. Summary of the Invention

[0003] The purpose of this application is to provide a heat dissipation device and a server that can reduce the assembly difficulty of the heat dissipation device and improve the assembly efficiency of the heat dissipation device.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] On one hand, this application provides a heat dissipation device. The heat dissipation device includes: at least one fan assembly, a front shell, a rear shell, an adapter, and multiple shock absorbers. The front shell and the rear shell are engaged with each other to enclose a receiving cavity. At least one fan assembly is installed in the receiving cavity, and the fan assembly includes a fan. The rear shell includes an air inlet panel, which includes an air inlet. The front shell includes an air outlet panel and an anti-backflow structure. The air outlet panel includes an air outlet, and the anti-backflow structure is located on the side of the air outlet panel near the fan assembly. The fan drives airflow from the air inlet into the receiving cavity, and then flows to the air outlet through the anti-backflow structure. The adapter is installed between the fan assembly and the anti-backflow structure. Of the multiple shock absorbers, some shock absorbers are installed between the fan assembly and the air inlet panel, and other shock absorbers are installed between the fan assembly and the adapter.

[0006] This application provides a heat dissipation device by adding an adapter between the anti-backflow structure of the front housing and the fan assembly. The fan assembly is connected to the air intake panel via a portion of a shock-absorbing component, and also connected to the adapter via another portion of the shock-absorbing component. This provides both cushioning and shock absorption, and helps prevent noise from the fan assembly. Furthermore, by adding the adapter and positioning it on the side of the anti-backflow structure opposite to the air outlet panel, the assembly of the shock-absorbing component is prevented from being obstructed by the anti-backflow structure, which would otherwise complicate the assembly of the heat dissipation device. In other words, connecting the shock-absorbing component to the adapter reduces the assembly difficulty and improves the assembly efficiency of the heat dissipation device.

[0007] In some embodiments, the adapter includes a plate body. The plate body has at least one ventilation hole and a plurality of first connection holes. At least two first connection holes are distributed around each ventilation hole. Fan holes correspond one-to-one with fans. A fan assembly includes at least one fan component. The fan assembly also includes a fan frame. The fan is located within the fan frame, and the fan's outlet side faces the ventilation hole. The fan frame has a plurality of second connection holes. A shock-absorbing member, installed between the fan assembly and the adapter, connects the first and second connection holes.

[0008] This design allows for the use of shock-absorbing components passing through both the first and second connecting holes, enabling the fan assembly and adapter to be secured using these components. This provides better stability and cushioning, and also helps prevent noise from the fan assembly.

[0009] In some embodiments, the air intake panel is provided with a plurality of third connection holes. The fan frame is also provided with a plurality of fourth connection holes. A shock absorber installed between the fan assembly and the air intake panel connects the third connection holes and the fourth connection holes.

[0010] This design allows for the use of shock-absorbing components that pass through the third and fourth connecting holes, enabling the fan assembly and rear housing to be secured with these components, thus providing a certain degree of cushioning and shock absorption. It also helps prevent noise from the fan assembly.

[0011] In some embodiments, the rear cover further includes opposing first and second side panels. The first side panel is fixedly connected to one side edge of the air inlet panel, and the second side panel is fixedly connected to the other side edge of the air inlet panel. The first side panel includes at least one first limiting member, and the second side panel includes at least one second limiting member. Both the first and second limiting members are engaged with the adapter to restrict the adapter from moving to the side away from the air inlet panel.

[0012] This design allows for the installation of a first and a second limiting member on the first and second side panels of the rear housing. Both the first and second limiting members engage with the adapter, restricting its movement away from the air intake panel. This improves the stability of the adapter, thus better securing the fan assembly and preventing vibration and noise issues.

[0013] In some embodiments, the heat dissipation device further includes at least one connector assembly. The connector assembly includes a connector body and a connector element. The connector body is used to electrically connect the fan assembly to an external device. The connector body is fixedly connected to a first side plate via the connector element. The connector body and the fan do not overlap in a first direction, which is the axial direction of the fan.

[0014] This configuration, where the connector assembly is fixedly connected to the first side plate and the connector body and fan do not overlap in the first direction, prevents the connector body from obstructing the fan, thus reducing the connector body's impact on fan airflow. This improves the heat dissipation effect of the cooling system.

[0015] In some embodiments, the first side plate is provided with a insertion slot and a snap fastener. The connector is provided with a insertion plate and a snap-fit ​​groove. The insertion plate is used to insert into the insertion slot, and the snap-fit ​​groove is used to snap into the snap fastener to fix the connector to the first side plate.

[0016] With this configuration, grooves (slots and insertion slots) and clips (insertion plates and buckles) are provided on the first side plate and the connector, respectively, so that the first side plate and the connector can be engaged with each other, further fixing the first side plate and the connector, ensuring the firmness of the connector assembly, and preventing misalignment of the first side plate and the connector, which could lead to problems such as the connector assembly detaching.

[0017] In some embodiments, the connector body is located at one end of the first side plate along the direction of the height of the heat dissipation device.

[0018] This configuration places the connector body at the bottom of the heat sink and connects it to the first side plate. This ensures that the connector body and the fan do not overlap in the first direction, and also prevents the connector body from protruding from the heat sink, thus improving the stability of the heat sink and reducing assembly difficulty. Furthermore, placing the connector body at the bottom of the heat sink facilitates insertion and connection of the connector body to external devices, increasing the flexibility of the connector assembly.

[0019] In some embodiments, the heat dissipation device further includes at least one connector assembly. The connector assembly includes a connector body and a connector element. The connector body is used to electrically connect the fan assembly to an external device. The connector body is fixedly connected to a second side plate via the connector element. The connector body and the fan do not overlap in a first direction, which is the axial direction of the fan.

[0020] This configuration, where the connector assembly is fixedly connected to the second side plate and the connector body and fan do not overlap in the first direction, prevents the connector body from obstructing the fan, thus reducing the connector body's impact on fan airflow. This improves the heat dissipation effect of the cooling system.

[0021] In some embodiments, the second side plate is provided with a insertion slot and a snap fastener. The connector is provided with a insertion plate and a snap-fit ​​groove. The insertion plate is used to insert into the insertion slot, and the snap-fit ​​groove is used to snap into the snap fastener to fix the connector to the second side plate.

[0022] With this configuration, grooves (slots and insertion slots) and clips (insertion plates and buckles) are provided on the second side plate and the connector, respectively, so that the second side plate and the connector can be engaged with each other, further fixing the second side plate and the connector, ensuring the firmness of the connector assembly, and preventing the second side plate and the connector from misaligning, which could lead to problems such as the connector assembly detaching.

[0023] In some embodiments, the connector body is located at one end of the second side plate along the direction of the height of the heat dissipation device.

[0024] This configuration places the connector body at the bottom of the heat sink and connects it to the second side panel. This ensures that the connector body and the fan do not overlap in the first direction, and also prevents the connector body from protruding from the heat sink, thus improving the stability of the heat sink and reducing assembly difficulty. Furthermore, placing the connector body at the bottom of the heat sink facilitates insertion and connection of the connector body to external devices, increasing the flexibility of the connector assembly.

[0025] In some embodiments, the connector further includes a sliding groove. The sliding groove includes opposing first and second sidewalls, and a snap-fit ​​opening is provided on the first sidewall. The connector body includes a sliding connecting plate and a snap-fit ​​protrusion. The sliding connecting plate includes opposing first and second surfaces, and the snap-fit ​​protrusion is located on the first surface. The sliding connecting plate is used to engage with the sliding groove, and the snap-fit ​​protrusion is used to snap into the snap-fit ​​opening, thereby fixing the connector body onto the connector.

[0026] This design allows the snap-fit ​​protrusions on the first surface to engage with the snap-fit ​​opening, thus securing the sliding connecting plate and the sliding groove, which in turn secures the connector body and the connector component, thereby improving the stability of the connector assembly. Furthermore, when the snap-fit ​​protrusions on the first surface engage with the snap-fit ​​opening, the second surface abuts against the second sidewall in the sliding groove, preventing the connector component from wobbling and consequently preventing the connector assembly from shaking, further enhancing its stability.

[0027] In some embodiments, at least one connector assembly includes a first connector assembly. The first connector assembly is located on the periphery of the fan frame. The corner portion of the fan frame has a clearance space for accommodating the first connector assembly.

[0028] This design provides clearance at the corner of the fan frame, allowing the first connector assembly to be placed within this clearance. This enables the first connector assembly to be placed inside the heatsink and connected to the third side plate for secure mounting. Furthermore, it maximizes the use of the heatsink's internal space, improving its space utilization and reducing its cost.

[0029] In some embodiments, at least one connector assembly includes a second connector assembly. The second connector assembly is located between the adapter and the anti-backflow structure. The ventilation holes of the second connector assembly and the adapter do not overlap in a first direction. The first direction is the axial direction of the fan.

[0030] This configuration, with a gap between the anti-backflow structure of the front frame and the adapter, allows the second connector assembly to be placed at the gap, i.e., between the adapter and the anti-backflow structure. This fully utilizes the internal space of the heat dissipation device, improving its space utilization rate and reducing costs. Simultaneously, ensuring that the ventilation holes of the second connector assembly and the adapter do not overlap in the first direction prevents the second connector assembly from obstructing the ventilation holes, reducing the impact of the connector body on the cooling fan's exhaust and improving the heat dissipation effect of the heat dissipation device.

[0031] In some embodiments, the air outlet panel includes a first end and a second end disposed opposite to each other. The anti-backflow structure includes a plurality of first anti-backflow fins and a plurality of second anti-backflow fins. The first anti-backflow fins are located near the first end, and the second anti-backflow fins are located near the second end. The first anti-backflow fins are used to deflect in a second direction to guide the airflow discharged from the heat dissipation device to the side near the first end. The second anti-backflow fins are used to deflect in a third direction to guide the airflow discharged from the heat dissipation device to the side near the second end.

[0032] This design allows the first and second anti-backflow plates to work together to guide the airflow exhausted from the fan along a first direction (the axial direction of the fan) away from the fan assembly. In other words, the combined action of the first and second anti-backflow plates directs the airflow exhausted from the fan along the first direction of the air outlet, away from the fan assembly. This helps to fully cover the air outlet of the heat dissipation device, increasing the air outlet area and improving the heat dissipation effect.

[0033] On the other hand, embodiments of this application provide a server. The server includes the heat dissipation device described in any of the above embodiments.

[0034] Since the server provided in the embodiments of this application includes the heat dissipation device as described above, it has all the beneficial effects of the heat dissipation device described above, and will not be repeated here. Attached Figure Description

[0057] Figure 1 This is a structural block diagram of a server provided in some embodiments of this application.

[0058] Embodiments of this application provide a server, such as Figure 1 As shown, server 200 includes a heat dissipation device 100 and a chassis 210. The heat dissipation device 100 can be placed inside the chassis 210.

[0059] Understandably, server 200 generates a significant amount of heat during operation. To prevent overheating from affecting the normal operation of server 200, a heat dissipation device 100 can be installed inside server 200. This device 100 externally drives cool air to enter server 200 from one side, where it exchanges heat with the internal components via convection. Finally, the hot air is carried away from the other side of server 200. This achieves heat dissipation for the internal components of server 200. The path of the cool air driven by the heat dissipation device 100 is as follows: Figure 1 As indicated by the middle arrow.

[0060] In some examples, server 200 also includes circuit board 220 to which heat sink 100 can be electrically connected. For example, heat sink 100 can be plugged into circuit board 220.

[0061] Figure 2 This is a structural diagram of a heat dissipation device provided in some embodiments of this application. Figure 3 for Figure 2 Exploded view of the heat dissipation device shown. Figure 4 for Figure 2 A schematic diagram of the middle and rear shell structure. Figure 5 for Figure 2 A schematic diagram of the structure of the fore-and-aft shell. Among them, Figure 3 China and Israel Figure 2 The explosion of the heat dissipation device 100 along the Y-axis is illustrated.

[0062] Embodiments of this application provide a heat dissipation device 100. For example... Figure 2 and Figure 3 As shown, the heat dissipation device 100 includes a fan module 10, a front shell 20, a rear shell 30, and a plurality of shock absorbers 50. The fan module 10 includes at least one fan assembly 11. The fan assembly 11 includes a fan 111. The heat dissipation device 100 can dissipate heat from the server 200 by utilizing the airflow generated by the fan 111.

[0063] Understandable. Figure 2 The accompanying drawings below only schematically illustrate some components of the heat dissipation device 100; the actual shape, size, location, and construction of these components are not subject to change. Figure 2 As well as the limitations of the accompanying figures below.

[0064] exist Figure 2 In the illustrated embodiment, the heat dissipation device 100 is rectangular. For ease of description in the following embodiments, an XYZ coordinate system is established. Specifically, the length direction of the heat dissipation device 100 is defined as the X-axis, the width direction as the Y-axis, and the height direction as the Z-axis. It is understood that the coordinate system setting of the heat dissipation device 100 can be flexibly configured according to actual needs, and is not specifically limited here.

[0065] like Figure 2 and Figure 3 As shown, the front shell 20 and the rear shell 30 are positioned opposite each other along the Y-axis. The front shell 20 and the rear shell 30 are connected to each other to form the accommodating cavity Q.

[0066] In some examples, such as Figure 3 , Figure 4 and Figure 5 As shown, the front housing 20 and the rear housing 30 are detachably connected. For example, the front housing 20 and the rear housing 30 can be snapped together so that the front housing 20 and the rear housing 30 enclose a receiving cavity Q.

[0067] For example, the front housing 20 may include at least one card interface F1, and the rear housing 30 may include at least one card connector F2. The card interface F1 on the front housing 20 and the card connector F2 on the rear housing 30 correspond one-to-one. When assembling the heat dissipation device 100, the card connector F2 on the rear housing 30 can be engaged with the card interface F1 on the front housing 20 to achieve a detachable connection between the front housing 20 and the rear housing 30. Thus, the front housing 20 and the rear housing 30 can be connected to each other to enclose the receiving cavity Q.

[0068] The front housing 20 and the rear housing 30 form the outer shell of the heat dissipation device 100. The front housing 20 and the rear housing 30 can be used to protect the electronic components inside the heat dissipation device 100. The materials of the front housing 20 include, but are not limited to, metal and plastic. To achieve a thinner and lighter heat dissipation device 100 while ensuring the structural strength of the front housing 20, the material of the front housing 20 can be metal. In some examples, the material of the rear housing 30 can be the same as that of the front housing 20. That is, the material of the rear housing can be metal.

[0069] The fan module 10 is installed within the accommodating cavity Q. That is, at least one fan assembly 11 is installed within the accommodating cavity Q. The fan assembly 11 can be fixed using the front housing 20 and the rear housing 30, and the front housing 20 and the rear housing 30 can also be used to protect the fan assembly 11.

[0070] In some examples, such as Figure 3 As shown, along the Z-axis, the fan module 10 may include multiple fan assemblies 11. That is, the multiple fan assemblies 11 are arranged along the height direction of the heat dissipation device 100. Figure 3 The illustration takes a fan module 10 that includes two fan assemblies 11 as an example. However, some embodiments of this application do not limit the number of fan assemblies 11 in the fan module 10 to this.

[0071] like Figure 4 As shown, the rear housing 30 includes an air intake panel 31, and the air intake panel 31 includes an air inlet 311. Wherein, Figure 4 Taking only the square air intake panel 31 and the circular air intake 311 as an example.

[0072] like Figure 5 and combination Figure 3 As shown, the front housing 20 includes an air outlet panel 21 and an anti-backflow structure 22. Among them, Figure 5 To clearly illustrate the structure of the air outlet panel 21, the backflow prevention structure 22 is not shown. The backflow prevention structure 22 can be combined with... Figure 3 As shown.

[0073] The air outlet panel 21 includes an air outlet 211. Among them, Figure 5 Taking only the square air outlet panel 21 and the round air outlet 211 as an example.

[0074] The anti-backflow structure 22 is located on the side of the exhaust panel 21 near the fan module 10. The anti-backflow structure 22 is located on the side of the exhaust panel 21 near the fan assembly 11, and can be used to prevent the airflow formed by the fan assembly 11 from flowing back and affecting the heat dissipation effect of the heat dissipation device 100.

[0075] To drive airflow through fan module 10 ( Figure 3 (As indicated by the middle arrow) Air flows into the accommodating cavity Q through the air inlet 311, and then flows to the air outlet 211 through the anti-backflow structure 22. That is, the fan module 10 can drive cool air into the heat dissipation device 100 from the air inlet 311 of the air inlet panel 31, and the cool air then flows out through the air outlet 211 of the air outlet panel 21. After convective heat exchange with the components inside the server 200, the hot air is finally carried out from the rear panel of the server. Based on this, heat dissipation is achieved for the components inside the server 200.

[0076] However, the inventors of this application discovered through research that when the fan assembly 11 operates at high speed, the faster the rotation speed, the greater the vibration, and the more air and mechanical noise it generates. To prevent the fan 111 within the fan assembly 11 from vibrating and generating noise during operation, shock absorbers 50 are used to fix the fan assembly 11 to the front housing 20 and the rear housing 30 respectively. Specifically, a portion of the shock absorbers 50a is installed between the fan assembly 11 and the air inlet panel 31, and another portion of the shock absorbers 50b is installed between the fan assembly 11 and the air outlet panel 21. However, because an anti-backflow structure 22 is provided between the fan assembly 11 and the air outlet panel 21, the anti-backflow structure 22 makes it difficult to align and install the shock absorbers 50b between the fan assembly 11 and the air outlet panel 21.

[0077] The heat dissipation device 100 provided in some embodiments of this application, combined with Figure 3 As shown, the heat dissipation device 100 also includes an adapter 40. The adapter 40 is installed between the fan assembly 11 and the anti-backflow structure 22. That is, the adapter 40 is located on the side of the anti-backflow structure 22 away from the exhaust panel 21. Based on this, a plurality of shock absorbers 50 are provided, including a portion of shock absorbers 50a and another portion of shock absorbers 50b. Among them, a portion of shock absorbers 50a is installed between the fan assembly 11 and the air intake panel 31, and the other portion of shock absorbers 50b is installed between the fan assembly 11 and the adapter 40. The shock absorbers 50 improve the connection stability between the fan assembly 11 and the rear housing 30, play a certain role in buffering and shock absorption, and prevent the fan assembly 11 from generating noise.

[0078] For example, the material of the shock absorber 50 includes, but is not limited to, rubber. Because rubber has a certain degree of resilience, it can better serve as a buffer and damper.

[0079] When installing the heat sink 100, a portion of the shock absorber 50a can be used to connect the fan assembly 11 to the air intake panel 31, and another portion of the shock absorber 50b can be used to connect the fan assembly 11 to the adapter 40. Then, the front shell of the heat sink 100 is assembled. Since the fan assembly 11 can be connected to the adapter 40 via the shock absorber 50b, and the fan assembly 11 does not need to be connected to the front shell 20 via the shock absorber 50b, the anti-backflow structure 22 inside the front shell 20 will not obstruct the shock absorber 50 during the installation of the heat sink 100. This reduces the assembly difficulty of the heat sink 100 and improves its assembly efficiency.

[0080] In summary, the heat dissipation device 100 provided in some embodiments of this application adds an adapter 40 between the anti-backflow structure 22 of the front shell 20 and the fan assembly 11. This allows the fan assembly 11 to be connected to the air intake panel 31 via a portion of the shock absorber 50a, and to the adapter 40 via another portion of the shock absorber 50b. This provides both cushioning and shock absorption, and helps prevent noise from the fan assembly 11. Furthermore, by connecting the shock absorber 50b to the adapter 40, the assembly of the shock absorber 50b is prevented from being obstructed by the anti-backflow structure 22, which would otherwise complicate the assembly of the heat dissipation device 100. In other words, connecting the shock absorber 50b to the adapter 40 reduces the assembly difficulty of the heat dissipation device 100 and improves its assembly efficiency.

[0081] In some embodiments, such as Figure 4 and combination Figure 3 As shown, the rear cover 30 also includes a first side plate 32 and a second side plate 33. The first side plate 32 is fixedly connected to one side edge of the air inlet panel 31, and the second side plate 33 is fixedly connected to the other side edge of the air inlet panel 31.

[0082] Based on this, the first side panel 32, the air inlet panel 31, and the second side panel 33 form a semi-enclosed structure. The fan assembly 11 can be installed within the semi-enclosed structure formed by the first side panel 32, the air inlet panel 31, and the second side panel 33, which serves to fix and protect the fan assembly 11.

[0083] Figure 6 for Figure 2 A schematic diagram of the structure of the fan assembly.

[0084] In some embodiments, such as Figure 4 , Figure 6 and combination Figure 3 As shown, the air inlet panel 31 of the rear cover 30 is provided with multiple third connection holes 312.

[0085] like Figure 6 As shown, the fan assembly 11 also includes a fan frame 112, with the fan 111 located within the fan frame 112. The fan frame 112 is also provided with a plurality of fourth connection holes 114. A shock absorber 50a, installed between at least one fan assembly 11 and the air inlet panel 31, connects the third connection hole 312 and the fourth connection hole 114.

[0086] Based on this, the fan assembly 11 can be installed between the first side plate 32 and the second side plate 33, and one side of the fan assembly 11 can be connected to the air inlet panel 31 by a shock absorber 50a. This serves both to fix the fan assembly 11 to a certain extent and to buffer and absorb vibrations, preventing noise from the fan assembly 11.

[0087] In some examples, the third connecting hole 312 and the fourth connecting hole 114 can be configured in a one-to-one correspondence. Along the Y-axis, the third connecting hole 312 and the fourth connecting hole 114 overlap, so that the two ends of the shock absorber 50a installed between the fan assembly 11 and the air inlet panel 31 are respectively connected to the third connecting hole 312 and the fourth connecting hole 114. Thus, the shock absorber 50a improves the connection stability between the fan assembly 11 and the rear housing 30, providing a certain degree of cushioning and shock absorption, and also helps prevent noise generation from the fan assembly 11.

[0088] In some embodiments, such as Figure 4 As shown, multiple third connection holes 312 are arranged circumferentially around the air inlet panel 31. That is, the multiple third connection holes 312 are distributed at various edges of the air inlet panel 31. Figure 4 The illustration is based on an example where the air inlet panel 31 has eight third connection holes 312.

[0089] Furthermore, a plurality of fourth connection holes 114 are arranged circumferentially around the fan frame 112. That is, the plurality of fourth connection holes 114 are distributed at various edges of the fan frame 112. Figure 6 The illustration is based on an example where the fan frame 112 has eight fourth connection holes 114.

[0090] Based on this, when the two ends of the shock absorber 50a are connected to the third connecting hole 312 and the fourth connecting hole 114 respectively, the shock absorber 50a can be used to fix the fan assembly 11 and the rear shell 30 at various positions on the edge, which can better fix the fan assembly 11 and the rear shell 30, play a certain role in buffering and shock absorption, and also help prevent the fan assembly 11 from generating noise.

[0091] Figure 7 for Figure 2 A schematic diagram of the intermediate connector.

[0092] In some embodiments, such as Figure 7 As shown, the adapter 40 includes a plate body 41. Along the Z-axis, the plate body 41 has at least one ventilation hole 411. A fan 111 and a ventilation hole 411 can be arranged in a one-to-one correspondence, so that the airflow generated by the fan 111 can flow through the ventilation hole 411 to the outside of the heat dissipation device 100. Furthermore, the plate body 41 has a plurality of first connection holes 412. At least two first connection holes 412 are distributed around each ventilation hole 411.

[0093] like Figure 6 As shown, the fan assembly 11 also includes a fan frame 112. The fan 111 is located inside the fan frame 112, and the air outlet side of the fan 111 faces the ventilation hole 411. The fan frame 112 is provided with a plurality of second connection holes 113. Among them, the shock absorber 50b installed between at least one fan assembly 11 and the adapter 40 connects the first connection hole 412 and the second connection hole 113.

[0094] After the fan assembly 11 is installed within the semi-enclosed structure formed by the first side plate 32, the air inlet panel 31, and the second side plate 33, and one side of the fan assembly 11 is connected to the air inlet panel 31 via a shock absorber 50a, that is, after one side of the fan assembly 11 is fixed, the other side of the fan assembly 11 can be connected to the adapter 40 via a shock absorber 50b. The adapter 40 and the air inlet panel 31 of the rear shell 30 can be used together to fix the fan assembly 11, which better plays a role in buffering and shock absorption, and prevents the fan assembly 11 from generating noise.

[0095] In some examples, the first connecting hole 412 and the second connecting hole 113 can be configured in a one-to-one correspondence. Along the Y-axis, the first connecting hole 412 and the second connecting hole 113 overlap, so that both ends of the shock absorber 50b, installed between the fan assembly 11 and the adapter 40, are connected to the first connecting hole 412 and the second connecting hole 113 respectively. This fixes the adapter 40 and the fan assembly 11, providing a certain degree of cushioning and shock absorption, and preventing noise from the fan assembly 11.

[0096] In some embodiments, such as Figure 7 As shown, a plurality of first connecting holes 412 are arranged circumferentially around the plate body 41. That is, the plurality of first connecting holes 412 are distributed at various edge positions of the plate body 41. Figure 7 The illustration is based on the main body 41 of the plate, which includes eight first connecting holes 412.

[0097] And, such as Figure 6 As shown, a plurality of second connection holes 113 are arranged circumferentially around the fan frame 112. That is, the plurality of second connection holes 113 are distributed at various edge positions of the fan frame 112. Figure 6The illustration is based on an example where the fan frame 112 has eight second connection holes 113.

[0098] Based on this, when the two ends of the shock absorber 50b are connected to the first connecting hole 412 and the second connecting hole 113 respectively, the shock absorber 50b can be used to fix the fan assembly 11 and the various positions on the edge of the adapter 40, which can better fix the adapter 40 and the fan module 10, play a certain role in buffering and shock absorption, and help prevent the fan assembly 11 from generating noise.

[0099] In some examples, along the Y-axis, the fan 111 at least partially overlaps with the vent 411 so that the airflow generated by the fan 111 can pass through the vent 411. In other examples, along the Y-axis, the fan 111 overlaps with the vent 411 so that more airflow generated by the fan 111 passes through the vent 411.

[0100] in, Figure 3 The illustration takes a fan module 10 comprising two fan assemblies 11 and a main body 41 having two ventilation holes 411 as an example. However, some embodiments of this application do not limit the number of fan assemblies 11 and ventilation holes 411 to this, and can be set according to the actual heat dissipation requirements. Compared to a heat dissipation device 100 with only one fan 111, a heat dissipation device 100 with two or more fans has a better heat dissipation effect and can better meet the heat dissipation requirements of the server 200.

[0101] In some embodiments, such as Figure 4 As shown, the first side panel 32 of the rear shell 30 includes at least one first limiting member 321, and the second side panel 33 of the rear shell 30 includes at least one second limiting member 331. Both the first limiting member 321 and the second limiting member 331 are engaged with the adapter 40, restricting the adapter 40 from moving to the side away from the air inlet panel 31.

[0102] Based on this, the fan assembly 11 can be installed in a semi-enclosed structure formed by the first side plate 32, the air inlet panel 31 and the second side plate 33, with one side of the fan assembly 11 connected to the air inlet panel 31 by a shock absorber 50a, and the other side of the fan assembly 11 connected to the adapter 40 by a shock absorber 50b; then the rear shell 30 and the adapter 40 are interlocked, and the adapter 40 is fixed by the first side plate 32 and the second side plate 33 of the rear shell 30, restricting the adapter 40 from moving to the side away from the air inlet panel 31.

[0103] After the adapter 40 is better secured by the rear cover 30, the air intake panel 31 of the adapter 40 and the rear cover 30 can be used together to secure the fan assembly 11, which can better play a role in buffering and shock absorption and prevent the fan assembly 11 from generating noise.

[0104] In some examples, the first side panel 32 and the second side panel 33 can be arranged opposite each other along the X-axis. An air inlet panel 31 is located between the first side panel 32 and the second side panel 33. The first side panel 32 is fixedly connected to one side edge of the air inlet panel 31, and the second side panel 33 is fixedly connected to the other side edge of the air inlet panel 31. The side of the first side panel 32 facing away from the air inlet panel 31 includes at least one first limiting member 321. The side of the second side panel 33 facing away from the air inlet panel 31 includes at least one second limiting member 331.

[0105] In other examples, the first side plate 32 and the second side plate 33 may also be arranged opposite each other along the Z-axis. Alternatively, in yet another embodiment, the first side plate 32 and the second side plate 33 may also be arranged along other directions intersecting the X-axis and perpendicular to the Y-axis. Figure 4 The illustration is based on the example of the first side plate 32 and the second side plate 33 being arranged relative to each other along the X-axis.

[0106] like Figure 7 As shown, along the X-axis, the adapter 40 includes a first edge 40a and a second edge 40b. The first edge 40a engages with the first limiting member 321, and the second edge 40b engages with the second limiting member 331, so that both the first limiting member 321 and the second limiting member 331 are engaged with the adapter 40. The first limiting member 321 and the second limiting member 331 are used to fix the adapter 40, restricting the adapter 40 from moving to the side away from the air inlet panel 31. This helps improve the stability of the adapter 40, thereby better securing the fan module 10 and preventing vibration and noise from the fan module 10.

[0107] in, Figure 4 The illustration takes the first side plate 32, which includes two first limiting members 321 arranged along the Z-axis, as an example, and the second side plate 33, which includes two second limiting members 331 arranged along the Z-axis, as an example. However, the embodiments of this application do not further limit the number of first limiting members 321 and the number of second limiting members 331.

[0108] In some embodiments, the number of first limiting members 321 on the first side plate 32 may be equal to the number of second limiting members 331 on the second side plate 33. It is understood that in other embodiments, the number of first limiting members 321 on the first side plate 32 may not be equal to the number of second limiting members 331 on the second side plate 33.

[0109] In some other embodiments, the first limiting member 321 and the second limiting member 331 at least partially overlap along the X-axis direction, which can help simplify the manufacturing process of the first side plate 32 and the second side plate 33. For example, the first limiting member 321 and the second limiting member 331 correspond one-to-one, and the first limiting member 321 and the second limiting member 331 overlap along the X-axis direction.

[0110] Figure 8 for Figure 4 A schematic diagram of the structure of the first limiting component.

[0111] In some embodiments, such as Figure 8 and combination Figure 4 As shown, the first side panel 32 includes at least one first opening M1, and a first limiting member 321 is located within the first opening M1. The first limiting member 321 is generally L-shaped and includes a first portion 3211 extending along the Y-axis and a second portion 3212 extending along the X-axis. The second portion 3212 protrudes relative to the first portion 3211 toward the fan module 10. This is to position the second portion 3212 on the side of the adapter 40 away from the air inlet panel 31, thereby restricting the movement of the adapter 40 toward the side away from the air inlet panel 31. Furthermore, the end of the first portion 3211 away from the second portion 3212 is used to connect with the edge of the first opening M1 near the air inlet panel 31, so that the end of the first portion 3211 away from the second portion 3212 is connected to the first side panel 32 of the rear housing 30.

[0112] With this configuration, the first limiting member 321 is positioned within the first opening M1 of the first side plate 32, and the end of the first limiting member 321 near the air inlet panel 31 is connected to the first side plate 32. Therefore, when assembling the adapter 40, fan module 10, and rear shell 30, the adapter 40 is pushed towards the air inlet panel 31, and the first edge 40a of the adapter 40 abuts against the surface of the first limiting member 321. Since the first limiting member 321 is positioned within the first opening M1 of the first side plate 32, only the end of the first limiting member 321 near the air inlet panel 31 is connected to the first side plate 32. Therefore, when the adapter 40 is pushed, the first limiting member 321 can move a certain distance away from the adapter 40, so that the adapter 40 can move from the side of the second part 3212 away from the air inlet panel 31 to the side of the second part 3212 close to the air inlet panel 31, so that the second part 3212 is located on the side of the adapter 40 away from the air inlet panel 31, thereby limiting the movement of the adapter 40 away from the air inlet panel 31. This further prevents the adapter 40 from wobbling in the Y-axis direction, improving the stability of the adapter 40. It also helps to prevent vibration and noise problems during the operation of the fan module 10.

[0113] In some examples, such as Figure 8 As shown, the second part 3212 includes a first surface S1 and a second surface S2 arranged opposite to each other along the Y-axis. The first surface S1 is closer to the air inlet panel 31 than the second surface S2. The second part 3212 also includes a third surface S3, which may be parallel to the Z-axis and Y-axis. The third surface S3 is located between the first surface S1 and the second surface S2. One edge of the third surface S3 is fixedly connected to the first surface S1. The other edge of the third surface S3 is fixedly connected to the second surface S2 through a first transition surface S10. The end of the first transition surface S10 facing away from the second surface S2 is closer to the air inlet panel 31 than the end closer to the second surface S2. By setting the first transition surface S10, it is beneficial to push the adapter 40 so that it moves from the side of the second part 3212 away from the air inlet panel 31 along the first transition surface S10 to the side of the second part 3212 close to the air inlet panel 31, so that the second part 3212 is located on the side of the adapter 40 away from the air inlet panel 31, which restricts the adapter 40 from moving to the side away from the air inlet panel 31.

[0114] The material of the second part 3212 can be a material with a certain degree of elasticity. For example, the material of the second part 3212 can be polycarbonate (PC) and acrylonitrile butadiene styrene copolymer (ABS). When the adapter 40 is pushed from the side of the second part 3212 away from the air inlet panel 31 along the first transition surface S10 to the side of the second part 3212 near the air inlet panel 31, the second part 3212 can deflect to a certain extent along its force direction, that is, deflect to a certain extent towards the side of the air inlet panel 31, which can make it easier to push the adapter 40 to the side of the second part 3212 near the air inlet panel 31. When the adapter 40 moves to the side of the second part 3212 near the air inlet panel 31, the second part 3212 restores its deformation to fix the adapter 40 and restrict the adapter 40 from moving away from the air inlet panel 31.

[0115] In other embodiments, such as Figure 4 As shown, the second side plate 33 includes at least one second opening M2, and a second limiting member 331 is located within the second opening M2. The second limiting member 331 is generally L-shaped. The structure of the second limiting member 331 can be the same as that of the first limiting member 321, and the structure of the second limiting member 331 can be combined with the above description of the first limiting member 321.

[0116] Specifically, the second limiting member 331 includes a third portion extending along the Y-axis and a fourth portion extending along the X-axis. The fourth portion protrudes relative to the third portion toward the fan module 10. This fourth portion is positioned on the side of the adapter 40 facing away from the air inlet panel 31, thus restricting movement of the adapter 40 toward the side facing away from the air inlet panel 31. Furthermore, the end of the third portion away from the fourth portion is used to connect with the edge of the second opening M2 near the air inlet panel 31. This end of the third portion away from the fourth portion connects to the second side plate 33 of the rear housing 30.

[0117] With this configuration, the second limiting member 331 is positioned within the second opening M2 of the second side plate 33, and the end of the second limiting member 331 near the air inlet panel 31 is connected to the second side plate 33. Therefore, when assembling the adapter 40, fan module 10, and rear shell 30, the adapter 40 is pushed towards the air inlet panel 31, and the second edge 40b of the adapter 40 abuts against the surface of the second limiting member 331. Since the second limiting member 331 is positioned within the second opening M2 of the second side plate 33, only the end of the second limiting member 331 near the air inlet panel 31 is connected to the second side plate 33. Therefore, when the adapter 40 is pushed, the second limiting member 331 can move a certain distance away from the adapter 40, so that the adapter 40 can move from the side of the fourth part away from the air inlet panel 31 to the side of the fourth part close to the air inlet panel 31, so that the fourth part is located on the side of the adapter 40 away from the air inlet panel 31, thereby limiting the movement of the adapter 40 away from the air inlet panel 31. This further prevents the adapter 40 from wobbling in the Y-axis direction, improving the stability of the adapter 40. It also helps to prevent vibration and noise problems during the operation of the fan module 10.

[0118] In some examples, the fourth portion includes a fourth surface and a fifth surface arranged opposite each other along the Y-axis. The fourth surface is closer to the air inlet panel 31 than the fifth surface. The fourth portion also includes a sixth surface, which is parallel to the Z-axis and Y-axis. The sixth surface is located between the fourth and fifth surfaces. One edge of the sixth surface is fixedly connected to the fourth surface. The other edge of the third surface and the fifth surface are fixedly connected via a second transition surface. The end of the second transition surface facing away from the fifth surface is closer to the air inlet panel 31 than the end closer to the fifth surface. This facilitates pushing the adapter 40 from the side of the fourth portion facing away from the air inlet panel 31 along the second transition surface to the side of the fourth portion closer to the air inlet panel 31, so that the fourth portion is located on the side of the adapter 40 facing away from the air inlet panel 31, thereby limiting the movement of the adapter 40 to the side facing away from the air inlet panel 31.

[0119] The fourth part can be made of a material with a certain degree of elasticity. For example, the fourth part can be made of polycarbonate (PC) or acrylonitrile butadiene styrene (ABS). When the adapter 40 is pushed from the side of the fourth part away from the air inlet panel 31 and moves along the second transition surface to the side of the fourth part closer to the air inlet panel 31, the fourth part can deflect to a certain extent along its force direction, that is, deflect to a certain extent towards the side closer to the air inlet panel 31, which makes it easier to push the adapter 40 to the side of the fourth part closer to the air inlet panel 31. When the adapter 40 moves to the side of the fourth part closer to the air inlet panel 31, the fourth part restores its deformation to fix the adapter 40 and restrict the adapter 40 from moving away from the air inlet panel 31.

[0120] Figure 9 for Figure 2 The first angle is the assembly diagram of the connector assembly and the rear shell. The first angle is the view along the direction from the third side plate 34 towards the fan module 10, that is, the first angle is the direction from the outside of the heat dissipation device 100 to the inside of the heat dissipation device 100.

[0121] In some embodiments of this application, such as Figure 9 and combination Figure 3 As shown, the heat dissipation device 100 also includes at least one connector assembly 60. The connector assembly 60 includes a connector body 61 and a connector 62. The connector body 61 is used to electrically connect the fan module 10 to an external device. The corresponding external device can drive the fan module 10 to operate, dissipating heat from the server 200. The rear housing 30 also includes a third side plate 34 fixedly connected to the edge of the air intake panel 31. The connector body 61 is fixedly connected to the first side plate 32 via the connector 62. The connector body 61 and the fan 111 do not overlap in a first direction, which is the axial direction of the fan 111.

[0122] The connector body 61 is fixedly connected to the first side plate 32 via the connector 62. That is, the connector body 61 is connected to the side plate of the rear shell 30, fixing the connector body 61 at the corner of the rear shell 30 of the heat dissipation device 100, which better prevents the connector body 61 from obstructing the airflow generated by the fan 111.

[0123] Furthermore, the connector body 61 and the fan 111 can be configured to not overlap in a first direction, which is the axial direction of the fan 111. This first direction is parallel to the Y-axis. This configuration better prevents the connector body 61 from blocking the fan 111, thereby reducing the impact of the connector body 61 on the airflow from the cooling fan 111.

[0124] In other embodiments, the connector body 61 and the air outlet 211 do not overlap in the first direction. The connector body 61 is fixedly connected to the third side plate 34 via a connector 62. This ensures that the connector body 61 and the fan 111 do not overlap in the first direction. Simultaneously, ensuring that the connector body 61 and the air outlet 211 do not overlap in the first direction prevents the connector body 61 from blocking the air outlet 211, further reducing the impact of the connector body 61 on the airflow from the cooling fan 111.

[0125] In some other embodiments, the connector body 61 and the air inlet 311 do not overlap in the first direction. The connector body 61 is fixedly connected to the third side plate 34 via a connector 62. This ensures that the connector body 61 and the fan 111 do not overlap in the first direction. Simultaneously, ensuring that the connector body 61 and the air inlet 311 do not overlap in the first direction prevents the connector body 61 from blocking the air inlet 311, further reducing the impact of the connector body 61 on the exhaust air of the cooling fan 111.

[0126] In some other embodiments, the connector body 61 may be configured to not overlap with the fan 111 in the first direction, the connector body 61 may not overlap with the air outlet 211 in the first direction, and the connector body 61 may not overlap with the air inlet 311 in the first direction. This can better prevent the connector body 61 from blocking the air outlet channel inside the heat dissipation device 100 and better reduce the impact of the connector body 61 on the air outlet of the cooling fan 111.

[0127] It is understood that in some other embodiments, the connector body 61 in the heat dissipation device 100 can be fixedly connected to the second side plate 33 via the connector 62. Fixing the connector body 61 to the second side plate 33 has a similar technical effect to fixing the connector body 61 to the first side plate 32, and this can be described in conjunction with the above description, so it will not be repeated here.

[0128] In some embodiments of this application, the side plate of the fixing connector 62 is not limited and can be either a first side plate 32 or a second side plate 33. Figure 9 The illustration is based solely on the example of the connector body 61 being fixedly connected to the first side plate 32 via the connector 62, but it is not limited to this.

[0129] In some examples, one end of the connector body 61 is electrically connected to an external device, and the other end of the connector body 61 is electrically connected to the fan module 10.

[0130] For example, when the fan module 10 in the heat dissipation device 100 includes multiple fan assemblies 11, the number of connector bodies 61 can be one, that is, one connector body 61 drives multiple fan assemblies 11. Alternatively, the connector bodies 61 can be configured to correspond one-to-one with the fan assemblies 11, that is, one connector body 61 drives one fan assembly 11.

[0131] For example, when the fan module 10 in the heat dissipation device 100 includes two fan assemblies 11, the number of connector bodies 61 can be one or two.

[0132] In this application, the number of connector bodies 61 placed within a heat dissipation device 100 is not further limited in the embodiments.

[0133] In some embodiments, such as Figure 9 As shown, the connector body 61 is located at one end of the third side plate 34 along the height direction of the heat dissipation device 100. The height direction of the heat dissipation device 100 is the Z-axis direction. Specifically, the connector body 61 can be positioned at the bottom of the heat dissipation device 100.

[0134] The connector body 61 is positioned at the bottom of the heat sink 100 and connected to the third side plate 34. This design ensures that the connector body 61 and the fan 111 do not overlap in the first direction, and also prevents the connector body 61 from protruding from the heat sink 100, thereby improving the stability of the heat sink 100 and reducing the assembly difficulty of the heat sink 100.

[0135] Furthermore, since the connector body 61 is located at the bottom of the heat dissipation device 100, it is also convenient for the connector body 61 in the connector assembly 60 to be plugged into external devices, thereby improving the pluggable flexibility of the connector assembly 60.

[0136] Figure 10 for Figure 2 The second angle is an assembly drawing of the connector assembly and the rear shell. The second angle is a view along the direction from the fan module 10 toward the third side plate 34, that is, the second angle is the direction from inside the heat dissipation device 100 to outside the heat dissipation device 100.

[0137] In some embodiments, such as Figure 9 and Figure 10 As shown, the third side plate 34 is provided with a plug-in groove 341 and a buckle 342. The connector 62 is provided with a plug-in plate 621 and a buckle groove 622; the plug-in plate 621 is used to plug into the plug-in groove 341, and the buckle groove 622 is used to snap into the buckle 342 to fix the connector 62 on the third side plate 34.

[0138] By providing a insertion slot 341 on the third side plate 34 and a corresponding insertion plate 621 on the connector 62, the insertion plate 621 on the connector 62 is inserted into the insertion slot 341 on the third side plate 34, thereby connecting the connector 62 to the third side plate 34. Furthermore, by providing a buckle 342 on the third side plate 34 and a slot 622 on the connector 62, the buckle 342 on the third side plate 34 is engaged with the slot 622 on the connector 62, thereby connecting the third side plate 34 to the connector 62.

[0139] With this configuration, grooves (slots 622 and insertion slots 341) and clips (insertion plates 621 and buckles 342) are provided on both the third side plate 34 and the connector 62, so that the third side plate 34 and the connector 62 can be engaged with each other, further fixing the third side plate 34 and the connector 62, ensuring the firmness of the connector assembly 60, and preventing misalignment of the third side plate 34 and the connector 62, which could lead to problems such as the connector assembly 60 detaching.

[0140] In some embodiments of this application, the way in which the connector 62 can be connected to the third side plate 34 is not limited to this; the above-described method is used as an example for illustration only.

[0141] In some examples, such as Figure 9 , Figure 10 and combination Figure 4 As shown, along the Z-axis, one end of the third side plate 34 includes a groove O, and a insertion slot 341 extends from the groove end of the groove O towards the other end of the third side plate 34. A latch 342 is located within the groove O, and its groove end extends away from the third side plate 34. Thus, by inserting the insertion plate 621 into the insertion slot 341 and engaging the latch 342 with the slot 622, the connector 62 is fixed at the groove O position of the third side plate 34. This design ensures that the connector body 61 and the fan 111 do not overlap in the first direction, and also prevents the connector body 61 from protruding from the heat dissipation device 100, thereby improving the stability of the heat dissipation device 100 and reducing the assembly difficulty of the heat dissipation device 100.

[0142] In other examples, the height of the connector assembly 60 and the depth of the recess O are approximately equal along the Z-axis. This allows the dimensions of the connector assembly 60 to match the dimensions of the recess O, enabling the connector assembly 60 to engage within the recess O. This facilitates the insertion and removal of the connector body 61 within the connector assembly 60 with external devices, improving the flexibility of the connector assembly 60's insertion and removal capabilities.

[0143] Additionally, it should be noted that due to certain uncontrollable errors (such as manufacturing process errors, equipment precision errors, measurement errors, etc.), the fluctuation range of the gap between the height of the connector assembly 60 and the depth of the groove O should not exceed the error threshold, and the height of the connector assembly 60 and the depth of the groove O should be approximately equal. This application does not specify a particular value for the error threshold; as long as the gap is within the error threshold range, the connector body 61 can be plugged into an external device.

[0144] Figure 11 for Figure 2 A schematic diagram of the connector assembly. Figure 12 for Figure 11 A schematic diagram of the middle connector. Figure 13 for Figure 11 A schematic diagram of the main body of the connector. (The diagram shows...) Figure 12 and Figure 13 All views are taken along the direction from the fan module 10 toward the third side panel 34.

[0145] In some embodiments, such as Figure 11 and Figure 12 As shown, the connector 62 is also provided with a sliding groove 623. The sliding groove 623 includes a first sidewall W1 and a second sidewall W2 facing each other, and the first sidewall W1 is provided with a snap-fit ​​opening K1.

[0146] like Figure 13 As shown, the connector body 61 is provided with a sliding connecting plate 611 and a snap-fit ​​protrusion 612. The sliding connecting plate 611 includes a first surface E1 and a second surface E2 facing each other, and the snap-fit ​​protrusion 612 is located on the first surface E1. The sliding connecting plate 611 is used to cooperate with the sliding groove 623 for connection, and the snap-fit ​​protrusion 612 is used to snap with the snap-fit ​​opening K1 to fix the connector body 61 on the connector 62.

[0147] The sliding groove 623 extends along the X-axis, the first sidewall W1 and the second sidewall W2 are arranged opposite to each other along the Z-axis, and the first surface E1 and the second surface E2 are arranged opposite to each other along the Z-axis.

[0148] During the assembly of connector assembly 60, the sliding connecting plate 611 on connector body 61 is slidably inserted into sliding groove 623 along the X-axis direction. At this time, the snap-fit ​​protrusion 612 on the first surface E1 of the sliding connecting plate 611 deforms within the sliding groove 623, causing the sliding connecting plate 611 to slide along the X-axis direction within the sliding groove 623. This continues until the sliding connecting plate 611 is pushed, causing the snap-fit ​​protrusion 612 to slide to the snap-fit ​​opening K1. Then, the snap-fit ​​protrusion 612 returns to its original shape, allowing it to insert into the snap-fit ​​opening K1, thus engaging with it. This further secures the sliding connecting plate 611 and sliding groove 623, thereby further securing the connector body 61 and connector 62 and improving the stability of connector assembly 60.

[0149] In some examples, the first sidewall W1 is positioned away from the third sideplate 34 relative to the second sidewall W2, meaning the first sidewall W1 is closer to the bottom of the heat sink 100 relative to the second sidewall W2. Similarly, the first surface E1 is positioned away from the third sideplate 34 relative to the second surface E2, meaning the first surface E1 is closer to the bottom of the heat sink 100 relative to the second surface E2. A snap-fit ​​protrusion 612 is located on the first surface E1. The second surface E2 is a horizontal plane.

[0150] The snap-fit ​​protrusion 612 on the first surface E1 engages with the snap-fit ​​opening K1, which can fix the sliding connecting plate 611 and the sliding groove 623, that is, fix the connector body 61 and the connector 62, thereby improving the stability of the connector assembly 60. When the snap-fit ​​protrusion 612 on the first surface E1 engages with the snap-fit ​​opening K1, the second surface E2 is a horizontal plane, which allows the second surface E2 to abut against the second sidewall W2 in the sliding groove 623, preventing the connector 62 from shaking, and thus preventing the connector assembly 60 from shaking, which further improves the stability of the connector assembly 60.

[0151] In some embodiments, such as Figure 13 and combination Figure 3 As shown, the connector body 61 includes a first component V1 and a second component V2. The first component V1 can be inserted into the second component V2. The first component V1 may include multiple hollow portions V11 extending along the Z-axis direction. The second component V2 may include multiple pin terminals V21. Figure 13 The diagram is illustrated using the 8-pin terminal V21 as an example.

[0152] Based on this, the fan 111 can be electrically connected to the pin terminal V21 of the second component V2 via a cable passing through the cutout V11 of the first component V1. This enables the connector body 61 of the connector assembly 60 to be electrically connected to the fan 111.

[0153] Furthermore, the second component V2 can be electrically connected to an external device. For example, the second component V2 can be plugged into an external device to achieve electrical connection. This external device can be a PCB circuit board within a server. However, some embodiments of this application do not limit the model of the external device electrically connected to the connector body.

[0154] Figure 14 for Figure 2 Assembly diagram of the central fan module, connector assembly, and anti-backflow structure.

[0155] In some embodiments, such as Figure 14 and combination Figure 6 As shown, at least one connector assembly 60 is a first connector assembly 60a. The first connector assembly 60a is located on the periphery of the fan frame 112. The corner portion G of the fan frame 112 has a clearance space R for accommodating the first connector assembly 60a.

[0156] A clearance space R is provided at the corner G of the fan frame 112, within which the first connector assembly 60a can be placed. This allows the first connector assembly 60a to be placed inside the heat sink 100 and connected to the third side plate 34 for fixation. Furthermore, it makes full use of the internal space of the heat sink 100, improving its space utilization rate and helping to reduce its cost.

[0157] In some examples, a recess can be provided on the side of the fan frame 112 near the bottom of the heat sink 100, forming a clearance space R, where the first connector assembly 60a is placed. Some embodiments of this application do not specifically limit the shape of the clearance space R, as long as the fan frame 112 can support the fan 111, and the volume of the clearance space R is maximized to reduce the installation difficulty of the first connector assembly 60a.

[0158] In some embodiments, such as Figure 14 As shown, the first connector assembly 60a has a dimension ranging from 7mm to 9mm in the X-axis direction.

[0159] When the dimension of the first connector assembly 60a in the X-axis direction is equal to or close to 7mm, the width of the first connector assembly 60a can be set to be smaller while meeting the size requirements of the connector body 61 for setting the connection pins. This can help reduce the size of the first connector assembly 60a, and thus help place the first connector assembly 60a in the clearance space R of the corner G of the fan frame 112, making full use of the internal space of the heat dissipation device 100, improving the space utilization rate of the heat dissipation device 100, and helping to reduce the cost of the heat dissipation device 100.

[0160] When the dimension of the first connector assembly 60a in the X-axis direction is equal to or close to 9mm, the width of the first connector assembly 60a can be set to be wider, which can help reduce the manufacturing difficulty of the connector body 61 of the first connector assembly 60a and facilitate the setting of the connection pins in the connector body 61, while ensuring that the first connector assembly 60a is placed in the clearance space R of the corner part G of the fan frame 112.

[0161] For example, the first connector assembly 60a has a dimension of 7 mm, 7.3 mm, 8 mm or 9 mm in the X-axis direction.

[0162] In some embodiments, such as Figure 14 As shown, the first connector assembly 60a has a dimension ranging from 15mm to 25mm in the Y-axis direction.

[0163] When the dimension of the first connector assembly 60a in the Y-axis direction is equal to or close to 15mm, the length of the first connector assembly 60a can be set to be shorter while meeting the size requirements of the connector body 61 for setting the connection pins. This can help reduce the size of the first connector assembly 60a, and thus help place the first connector assembly 60a in the clearance space R of the corner part G of the fan frame 112, making full use of the internal space of the heat dissipation device 100, improving the space utilization rate of the heat dissipation device 100, and helping to reduce the cost of the heat dissipation device 100.

[0164] When the dimension of the first connector assembly 60a in the Y-axis direction is equal to or close to 25mm, the length of the first connector assembly 60a can be set to be longer while satisfying the requirement of placing the first connector assembly 60a in the clearance space R of the corner part G of the fan frame 112. This can help reduce the manufacturing difficulty of the connector body 61 of the first connector assembly 60a and facilitate the setting of the connection pins in the connector body 61.

[0165] For example, the first connector assembly 60a has a dimension of 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 20.3mm, 21mm, 22mm, 23mm, 24mm, or 25mm in the Y-axis direction.

[0166] In some embodiments, such as Figure 14 As shown, the dimensions of the first connector assembly 60a in the Z-axis direction range from 12mm to 15mm.

[0167] When the dimension of the first connector assembly 60a in the Z-axis direction is equal to or close to 12mm, the height of the first connector assembly 60a can be set to be lower while meeting the size requirements of the connector body 61 for setting the connection pins. This can help reduce the size of the first connector assembly 60a, and thus help place the first connector assembly 60a in the clearance space R of the corner part G of the fan frame 112, making full use of the internal space of the heat dissipation device 100, improving the space utilization rate of the heat dissipation device 100, and helping to reduce the cost of the heat dissipation device 100.

[0168] When the dimension of the first connector assembly 60a in the Z-axis direction is equal to or close to 15mm, the height of the first connector assembly 60a can be set higher, which can help reduce the manufacturing difficulty of the connector body 61 of the first connector assembly 60a and facilitate the setting of the connection pins in the connector body 61, while ensuring that the first connector assembly 60a is placed in the clearance space R of the corner part G of the fan frame 112.

[0169] For example, the first connector assembly 60a has a dimension of 12mm, 12.4mm, 13mm, 14mm or 15mm in the Z-axis direction.

[0170] In some embodiments, such as Figure 14 As shown, at least one connector assembly 60 is a second connector assembly 60b. The second connector assembly 60b is located between the adapter 40 and the anti-backflow structure 22. The second connector assembly 60b and the ventilation hole 411 of the adapter 40 do not overlap in a first direction; the first direction is the axial direction of the fan 111. The first direction is parallel to the Y-axis direction.

[0171] A gap exists between the anti-backflow structure 22 of the front housing 20 and the adapter 40, allowing the second connector assembly 60b to be placed at this gap, i.e., positioned between the adapter 40 and the anti-backflow structure 22. This fully utilizes the internal space of the heat dissipation device 100, improving its space utilization and reducing its cost. Simultaneously, the second connector assembly 60b and the ventilation hole 411 of the adapter 40 are prevented from overlapping in the first direction. This prevents the second connector assembly 60b from blocking the ventilation hole 411, reducing the impact of the connector body 61 on the exhaust air of the cooling fan 111 and improving the heat dissipation effect of the heat dissipation device 100.

[0172] In some embodiments, the dimensions of the second connector assembly 60a may be substantially the same as those of the first connector assembly 60a, which can be described in conjunction with the description of the dimensions of the first connector assembly 60a, and will not be repeated here.

[0173] In some other embodiments, such as Figure 14As shown, the number of connector assemblies 60 can be multiple, including a first connector assembly 60a and a second connector assembly 60b. The first connector assembly 60a is located on the periphery of the fan frame 112. The corner portion G of the fan frame 112 has a clearance space R for accommodating the first connector assembly 60a. Furthermore, at least one connector assembly 60 includes a second connector assembly 60b. The second connector assembly 60b is located between the adapter 40 and the anti-backflow structure 22. The second connector assembly 60b does not overlap with the ventilation hole 411 of the adapter 40 in a first direction; the first direction is the axial direction of the fan 111.

[0174] When the fan module 10 in the heat dissipation device 100 includes multiple fan assemblies 11, the heat dissipation device 100 can be configured to include a first connector assembly 60a and a second connector assembly 60b, which respectively drive different fan assemblies 11.

[0175] Based on this, the first connector assembly 60a can be positioned on the periphery of the fan frame 112. The corner portion G of the fan frame 112 has a clearance space R, which is used to avoid the first connector assembly 60a. Furthermore, the second connector assembly 60b can be positioned between the adapter 40 and the anti-backflow structure 22. The second connector assembly 60b and the ventilation hole 411 of the adapter 40 do not overlap in the first direction.

[0176] This configuration allows the first connector assembly 60a and the second connector assembly 60b to be placed inside the heat dissipation device 100, with both assemblies connected to the third side plate 34 for fixation. Furthermore, it fully utilizes the internal space of the heat dissipation device 100, improving its space utilization rate and reducing its cost.

[0177] In some examples, the first connector assembly 60a and the second connector assembly 60b at least partially overlap along the first direction. The first connector assembly 60a and the second connector assembly 60b can be centrally located, which facilitates subsequent maintenance of the heat dissipation device 100 and fully utilizes the internal space of the heat dissipation device 100, improving its space utilization and reducing its cost. For example, the first connector assembly 60a and the second connector assembly 60b overlap along the first direction.

[0178] In some implementations, the air outlet panel 21 includes a first end T1 and a second end T2 disposed opposite to each other. The anti-backflow structure 22 includes a plurality of first anti-backflow vanes 221. The plurality of first anti-backflow vanes 221 are all deflected toward the side closer to the first end T1. Alternatively, the anti-backflow structure 22 includes a plurality of second anti-backflow vanes 222, and the plurality of second anti-backflow vanes 222 are all deflected toward the side closer to the second end T2. That is, the plurality of anti-backflow vanes (first anti-backflow vanes 221 or second anti-backflow vanes 222) in the anti-backflow structure 22 are all deflected toward one end of the air outlet panel 21.

[0179] However, the inventors of this application have discovered through research that because the multiple anti-backflow plates in the anti-backflow structure 22 are all deflected toward one end of the air outlet panel 21, the anti-backflow plates cannot fully cover the air outlet 211 with the airflow discharged by the fan 111.

[0180] For example, multiple anti-backflow vanes are all deflected towards the side closer to the first end T1. These vanes direct the airflow exhausted by the fan 111 towards the side closer to the first end T1. Similarly, multiple anti-backflow vanes near the second end T2 also direct the airflow exhausted by the fan 111 towards the side closer to the first end T1. This results in no airflow flowing in the space along the Z-axis away from the fan module 10 where the anti-backflow vane closest to the second end T2 is located. In other words, when multiple anti-backflow vanes are all deflected towards one end of the air outlet panel 21, they cannot fully cover the air outlet 211 with the airflow exhausted by the fan 111.

[0181] Figure 15 for Figure 2 Assembly diagram of the front shell and anti-backflow structure.

[0182] In some embodiments of this application, the heat dissipation device 100, such as Figure 15 As shown, the air outlet panel 21 includes a first end T1 and a second end T2 disposed opposite to each other. The anti-backflow structure 22 includes a plurality of first anti-backflow plates 221 and a plurality of second anti-backflow plates 222. The first anti-backflow plates 221 are located near the first end T1, and the second anti-backflow plates 222 are located near the second end T2. The first anti-backflow plates 221 are deflected in a second direction C1 to guide the airflow discharged from the heat dissipation device 100 to the side closer to the first end T1. The second anti-backflow plates 222 are deflected in a third direction C2 to guide the airflow discharged from the heat dissipation device 100 to the side closer to the second end T2.

[0183] The air outlet panel 21 includes a first end T1 and a second end T2 arranged opposite to each other along the X-axis. The anti-backflow structure 22 includes a plurality of first anti-backflow plates 221 near the first end T1 and a plurality of second anti-backflow plates 222 near the second end T2.

[0184] A first anti-backflow plate 221 is deflected in the second direction C1 near the first end T1 to guide the airflow discharged from the fan 111 towards the side near the first end T1. That is, the first anti-backflow plate 221 is deflected towards the first end T1. Thus, the first anti-backflow plate 221 can guide the airflow discharged from the fan 111 into the space area along the Y-axis away from the side of the fan module 10.

[0185] Conversely, a second anti-backflow plate 222 is positioned near the second end T2 and deflected in the third direction C2 to guide the airflow discharged from the fan 111 towards the side near the second end T2. That is, the second anti-backflow plate 222 is positioned near the second end T2 and deflected towards the second end T2. Thus, the second anti-backflow plate 222 can guide the airflow discharged from the fan 111 into the space region along the Y-axis away from the side of the fan module 10.

[0186] Based on this, the first anti-backflow plate 221 and the second anti-backflow plate 222 can work together to guide the airflow exhausted by the fan 111 towards the space area on the side of the anti-backflow structure 22 away from the fan module 10 along the Y-axis. That is, the first anti-backflow plate 221 and the second anti-backflow plate 222 can work together to guide the airflow exhausted by the fan 111 towards the space area on the side of the air outlet 211 away from the fan module 10 along the Y-axis. This helps to fully cover the air outlet 211 of the heat dissipation device 100, increase the air outlet area of ​​the heat dissipation device 100, and improve the heat dissipation effect of the heat dissipation device 100.

Any variations or substitutions conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
