The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.

In operation, components within the chassis of a network communication device typically emit a significant amount of heat. In order to ensure that the components in the case can work normally, a heat dissipation device is arranged in the case to dissipate heat of the components. The air supply angle of the heat dissipating device is fixed, so that the components in the chassis cannot be covered completely, and further, the components in the chassis cannot be dissipated completely.

In order to solve the problem that the air supply angle of the heat radiator is fixed, the components in the chassis cannot be comprehensively cooled. The application provides a heat abstractor is fixed in order to solve heat abstractor air supply angle, can't carry out comprehensive radiating problem to the component of quick-witted incasement. As shown in fig. 1, the heat dissipating device 100 includes a blower fan 1, a connection assembly 2, and a driving member 3. Wherein, fan 1 is connected with coupling assembling 2, and further, drive piece 3 is connected with coupling assembling 2, and drive piece 3 is used for driving coupling assembling 2 and rotates around the first axis, and fan 1 and drive piece 3 interval preset distance in the plane of perpendicular and first axis. In this way, the driving piece 3 can drive the connecting component 2 to rotate, and then drive the fan 1 connected with the connecting component 2 to rotate, so that the fan 1 can change positions to change the air supply angle of the fan 1 when working, and then the fan 1 can perform more comprehensive heat dissipation on elements in a case.

Next, it is explained how the driving member 3 drives the connection assembly 2 to rotate, referring to fig. 1, the connection assembly 2 rotates around the first axis Z under the driving of the driving member 3, and the fan 1 and the driving member 3 are spaced a predetermined distance in a plane perpendicular to the first axis Z. Thus, when the driving member 3 drives the connection assembly 2 to rotate, the fan rotates in a plane perpendicular to the first axis with the first axis as a center line. Under the condition, when the fan 1 works to radiate heat of elements in the case, the driving piece 3 works and drives the connecting assembly 2 to rotate, so that the fan 1 connected with the connecting assembly 2 rotates, and the air supply angle of the fan 1 is changed accordingly to radiate heat of elements at different positions in the case.

In some embodiments of the present application, the fan 1 and the driving member 3 are located on the same side of the connection assembly 2 in the extending direction of the first axis. In this case, the fan 1 is operated in the same direction as the Z direction in fig. 1.

In other embodiments of the present application, the fan 1 and the driving member 3 are located on opposite sides of the connection assembly 2 in the extending direction of the first axis, respectively. In this case, the blower 1 is operated in the same direction as the Y direction in fig. 1.

In this way, the installation position of the fan 1 can be adjusted according to the position where the heat sink 100 is installed in the communication device casing. For example, when the fan 1 and the driving member 3 are located on the same side of the connection assembly 2 in the extending direction of the first axis, the blowing direction of the fan 1 is the Z direction, and the heat dissipating device 100 may be disposed in the communication device chassis at a position near the bottom, so that the wind blows from bottom to top. Or, when the fan 1 and the driving piece 3 are located at two opposite sides of the connecting component 2 in the extending direction of the first axis, the blowing direction of the fan 1 is the Y direction, and the heat dissipating device can be arranged in the communication equipment chassis at a position close to the top at this time, so that the wind blows from top to bottom.

Next, the structure of the above-described connection assembly 2 will be further described, and as shown in fig. 1, the connection assembly 2 further includes a connection block 21, and the connection block 21 is connected to the driving member 3. In this way, the connecting block 21 can be driven to rotate when the driving member 3 is operated.

On the basis of this, the connection assembly 2 further comprises a transmission assembly 2, which transmission assembly 2 is connected to the connection block 21. In this way, when the driving member 3 drives the connection block 21 to rotate, the transmission assembly 2 can rotate with the connection block 21.

Further, the above-described transmission assembly 2 includes a connection rod 221, a gear pair structure, and a mount. Wherein the connecting rod 221 is rotatably connected with the connecting block 21, and the fan 1 is corresponding to and connected with the connecting rod 221. Thus, when the driving piece 3 drives the connecting block 21 to rotate, the connecting rod 221 rotationally connected with the connecting block 21 rotates along with the connecting block 21, and then the fan 1 connected with the connecting rod 221 is driven by the connecting rod 221 and rotates in a plane perpendicular to the first axis, so that the air supply angle of the fan 1 is changed, and the purpose of radiating different elements in the chassis of the communication equipment is achieved.

Further, the above gear pair structure includes a gear 222 and a mating portion, wherein the gear 222 is connected to an end of the connecting rod 221 remote from the connecting block 21. In this case, when the gear 222 rotates, the gear 222 may drive the connecting rod 221 to rotate, for example, when the gear 222 rotates along the direction a in fig. 1, the connecting rod 221 connected to the gear 222 will also rotate along the direction a, and further drive the fan 1 connected to the connecting rod 221 to swing along the direction b, so as to further increase the coverage range of the air supply angle of the fan 1.

In addition, the transmission assembly 2 further comprises the mounting seat 223, and the mounting seat 223 is sleeved on the connecting rod 221. The blower 1 is connected with the connecting rod 221 through the mounting seat 223.

To enable rotation of the gear wheel 222, the heat sink 100 further comprises a guide ring 4, which guide ring 4 is located on the side of the transmission assembly 2 remote from the driver 3, and the central axis of the guide ring 4 coincides with the first axis. In this way, the distance from the connecting rod 221 to each position of the guide ring 4 can be ensured to be the same while the driving member 3 drives the connecting block 21 to rotate.

On this basis, the above-mentioned mating portion is provided on the side of the guide ring 4 facing the transmission assembly 2, and the mating portion includes the engaging portion 41 and the smoothing portion 42 which are arranged in order along the circumferential direction of the guide ring 4 and are provided adjacently. The engagement portion 41 is provided with teeth for engaging with the gear 222, and the smooth portion 42 and the gear 22 have a gap in the extending direction of the first axis.

Thus, the gear 222 is engaged with the engagement portion 41 of the mating portion during rotation of the connection lever 221. Since the connection rod 221 is rotatably connected to the connection block 21, the gear 222 rotates, for example, in the direction a (see fig. 1) when the gear 222 is engaged with the engagement portion 41 during rotation of the connection block 21 to drive the connection rod 221.

Further, the rotation of the gear 222 will drive the connecting rod 221 connected to the gear 222 to rotate, so that when the fan 1 connected to the connecting rod 221 rotates around the first axis as the center line, the fan 1 will swing, for example, swing along the direction b (see fig. 1), and the air supply angle of the fan 1 will also change during the swing of the fan 1. Facilitating the flow of air within the chassis and being able to cover more components.

Further, since the smooth portion 42 and the gear 222 have a gap therebetween, the gear 222 is separated from the gear teeth, and then the gear 222 and the smooth portion 42 have a gap therebetween. Therefore, the gear 222 does not rotate any more and rotates in the opposite direction to the direction a by the gravity of the fan 1 connected thereto, that is, the fan 1 will fall back to the position where no rotation occurs by the gravity after the gear 222 is disengaged from the engagement portion 41. Further, in the process that the driving piece 3 drives the connecting block 21 to rotate, when the gear 222 is meshed with the meshing part 41 again, the gear 222 drives the connecting rod 22 to rotate again, and then drives the fan 1 connected with the connecting rod to swing again.

In some embodiments of the present application, as shown in fig. 1, the transmission assembly 2 further includes at least one spring 23, one end of the spring 23 is connected to the connection block 21, and the other end is connected to the mounting seat 223.

In this case, when the driving member 3 drives the connection block 21 to rotate, the gear 222 of the end of the connection rod 221 connected to the connection block 21 away from the connection block 21 is engaged with the engagement portion 41. The gear 222 rotates, and the connection rod 221 also rotates along with the gear 222, so that the fan 1 connected with the connection rod 221 also swings. Based on this, the spring 23, one end of which is connected to the connection block 21 and the other end of which is connected to the mount 223, is elastically deformed. And when the gear 222 is not engaged with the engagement portion 41 any more, the spring 23 is not stretched or compressed any more and the deformation is restored.

In this way, under the combined action of the dead weight of the fan 1 and the spring 23, the fan 1 can be ensured to fall back to the position before swinging when the gear 222 is not meshed with the meshing part 41, the interference between the excessive rotation angle of the fan 1 and other components is avoided, and the normal operation of the fan 1 is ensured.

On the basis, as shown in fig. 1, the heat dissipating device 100 provided by the application further comprises a bearing ring 5, the bearing ring 5 is located on one side of the guide ring 4 where the meshing part 41 is arranged, and the central axis of the bearing ring 4 coincides with the central axis of the guide ring 4, based on which the transmission assembly 2 further comprises a bearing rod 51. Further, as shown in fig. 2 (fig. 2 is a view of fig. 1), a guide rail 50 is provided on the side of the carrier ring 5 facing the engagement portion 41. Further, one carrier bar 51 corresponds to and is connected with one connecting bar 221. Further, one end of one of the carrier bars 51 has a slider 511, the slider 511 is slidably connected to the guide rail 50, and the other end of the carrier bar 51 is rotatably fitted to the connection bar 221.

Based on this, when the driving member 3 operates and drives the connection block 21 and the connection rod 221 connected to the connection block 21 to rotate, since the connection rod 221 is in a rotating fit with the carrier rod 51. In this way, when the gear 222 drives the connecting rod 221 to rotate, the rotation of the connecting rod 221 is not affected because the connecting rod 221 is in rotation fit with the carrier rod 51. Further, since the end of the bearing rod 51 far away from the connecting rod 221 is provided with the sliding block 511, and the sliding block 511 is in sliding fit with the guide rail 50 and plays a supporting or bearing role on the bearing rod 51, the transmission assembly 2 is supported or bearing by the supporting rod 51.

In this way, the connecting rod 22 can be supported by the bearing rod 51, so as to support the whole connecting assembly 2, so that the force applied to the driving member 3 when the driving member 3 is in transmission connection with the connecting assembly 2 is reduced, and the driving member 3 can work normally.

In some embodiments of the present application, the fan 1 is multiple, and the transmission assembly 2 is multiple. Based on this, the plurality of transmission assemblies 2 are in one-to-one correspondence with the plurality of fans 1. In a plane perpendicular to the first axis, the vertical projections of the fans 1 are distributed in an annular array with the vertical projection of the first axis as a center.

For example, the fans 1 may be four, and the vertical projections of the four fans 1 are distributed in an annular array centered on the vertical projection of the first axis (fig. 1). In this case, the number of transmission assemblies 2 is also four, and one transmission assembly 2 corresponds to one fan 1. And, the number of the carrying bars 51 and the mating parts for carrying the transmission assembly 2 is also four. In this way, the driving member 3 drives the connection block 21 to rotate, and the transmission assembly 2 connected to the connection block 21 rotates along with the rotation, so that the four fans 1 rotate around the first axis as the center line. The heat dissipation of the components in the chassis can be performed by four fans 1.

On this basis, the communication device 200 further includes the heat dissipating device 100, and the heat dissipating device 100 is disposed in the accommodating cavity and connected to the chassis 201. Further, the heat sink 100 is disposed adjacent to one of the top plate 2011 and the bottom plate 2012, and the fan 1 faces the other of the top plate 2011 and the bottom plate 2012.

For example, when the heat dissipating device 100 is disposed adjacent to the top plate 2011, the fan 1 is disposed toward the bottom plate 2012, so that the blowing direction of the fan 1 is toward the bottom plate 2012, and the wind is blown from top to bottom. When the heat dissipating device 100 is disposed adjacent to the bottom plate 2012, the fan 1 is disposed towards the top plate 2011, such that the blowing direction of the fan 1 is towards the top plate 2011, and the wind blows from bottom to top.

The transmission capacity of 6G may be 100 times higher than 5G and the network delay may be reduced from milliseconds to microseconds. The chassis typically includes a housing, a rack, various switches on a panel, indicator lights, and the like. When the 5G network communication equipment cabinet is used, the internal electronic components work, so that the heat is serious, and the work of the 5G network communication equipment cabinet is seriously influenced. The position of the existing heat radiation structure is fixed, and the components inside the case cannot be covered completely, so that part of components cannot radiate timely, the service life of the heat radiation structure is reduced, and the work of the case of the 6G network communication equipment is seriously affected.
