Referring to fig. 1, as shown in fig. 1, an embodiment of the present application provides a heat dissipation device, including: a base 10 and a plurality of fans 11 arranged in parallel on the base 10;

one of the fans 11 includes: an impeller 111 and a driving module 12 connected to the impeller 111;

the driving module 12 is used for driving the impeller 111 to rotate so as to form a wind field;

the driving components of the fans 11 are different, and when the wind fields of the fans 11 are at least partially overlapped, turbulence for heat dissipation is formed.

The maximum output power of the plurality of fans 11 and the size and material of the impeller 111 may be the same or different. In addition, when the plurality of fans included in the heat dissipating device are disposed on the base, the heights of the fans may be the same or different, which is not limited in the embodiment of the present application.

Note that, only 3 fans 11 are shown in fig. 1, but the number of fans 11 in the embodiment of the present application is not limited, and the number of fans 11 included in the heat dissipating device may be set according to actual needs.

In some embodiments, the plurality of fans may be arranged in a matrix, not limited to the in-line arrangement shown in fig. 1.

Referring to fig. 2 and 3, for example, 4 fans may be arranged in a horizontal or vertical line, or may be arranged in two rows and two columns.

For example, when the object to be heat-radiated is an object and the volume or heat generation amount is large, a larger number of fans 11, for example, 6, 8, or more, may be provided on the base 10 of the heat-radiating apparatus.

When the object to be heat-radiated is an object and the volume or heat generation amount is small, a small number of fans 11, for example, 2, 3, or 4, may be provided on the base 10 of the heat-radiating apparatus.

Since the driving component of each fan 11 can drive the corresponding impeller 111 to change the air supply speed and the air supply direction, when the wind fields of different fans 11 at least partially overlap, the wind sent by different fans 11 will interfere with each other, so as to cause continuous change of the direction, the radiation range and the wind speed of the wind sent by the whole heat dissipating device.

Based on this, when the number of fans 11 included in the heat dissipating device is large, the frequency of disturbance and the range of disturbance between the wind blown out by each fan 11 are also large, and thus the speed and the direction of the wind blown out by the heat dissipating device are changed more frequently and are closer to the natural wind. Therefore, when the object to be heat-radiated is a person, a larger number of fans 11 can be provided on the base 10 of the heat radiation apparatus.

When a plurality of fans 11 are arranged in parallel on the base 10, the distance between two adjacent fans 11 is too long, and the wind blown by the two fans 11 may not be disturbed or disturbed weakly. And if the two fans 11 are too close, the normal rotation and swing of the fans 11 are affected. Therefore, the distance between two adjacent fans 11 can be set to be the air blowing distance of the fan 11 having the smaller power among the two fans 11.

For example, when the air blowing distance of one fan 11 is 1 to 1.5m and the air blowing distance of the other adjacent fan 11 is 2 to 3m, the distance between the two fans 11 may be set to 1 to 1.5m.

In addition, when a plurality of fans 11 are disposed in parallel on the base 10, the impellers 111 of the fans 11 located at both sides may be inclined toward one side of the fan 11 located at the middle, so that the area and the overlapping time in which the wind fields overlap between the respective fans 11 may be increased when the heat sink apparatus is in an operating state.

The driving module 12 of at least one fan 11 of the plurality of fans 11 may drive the impeller 111 of the fan 11 to rotate along a plane parallel to the base 10 and/or swing along a plane perpendicular to the base 10, so as to improve the radiation range of the wind sent out by each fan 11 and the disturbance effect between the wind sent out by each fan, so that the flow field of the wind sent out by the heat dissipation device is continuously changed, and the wind sent out by the heat dissipation device is more similar to natural wind.

In one embodiment, the impeller 111 of each fan 11 of the plurality of fans 11 included in the heat dissipating device may be further sleeved with a mesh-shaped protection cover, so as to reduce injury to surrounding people or objects caused by the rotation process of the impeller 111.

In another embodiment, a protective cover may be provided for the entire heat dissipating device, that is, all impellers 111 in the heat dissipating device are sleeved in the same protective cover.

In this embodiment of the present application, since the heat dissipating device includes a plurality of fans, and the wind fields of the plurality of fans can at least partially overlap, based on this, the wind sent out by each fan may generate mutual disturbance, so that the flow field of the wind sent out from the heat dissipating device is continuously changed, and turbulence is formed to be closer to natural wind, thereby reducing the wind field of the heat dissipating device to face in one direction, and causing discomfort to the user in the use process.

Referring to fig. 4 to 6, in one embodiment, one of the driving modules 12 includes:

a support shaft 121 mounted on the base 10; the support shaft 121 of the impeller 111 is different; wherein the support shaft 121 is configured to rotate in a plane of the base 10;

and a swing shaft 122 mounted on the support shaft 121, wherein a swing plane of the swing shaft 122 is perpendicular to a rotation plane of the support shaft 121, and the swing shaft 122 is different from the swing shaft 122 of the impeller 111.

Illustratively, a cylinder may be fixed to an end of the support shaft 121 near the base 10, a cylinder smaller than an inner diameter of the cylinder may be correspondingly disposed on the base 10, and the support shaft 121 may be mounted on the base 10 by sleeving the cylinder on the cylinder of the base 10.

Illustratively, the end of the support shaft 121 near the base 10 may be fixed with a cylinder, and correspondingly, the base 10 is provided with a cylinder larger than the outer diameter of the cylinder, and the support shaft 121 may be mounted on the base 10 by inserting the cylinder into the cylinder.

The above is merely an example, and the arrangement of the support shaft 121 on the base 10 is not limited to the arrangement of the support shaft 121 on the base 10 in the embodiment of the present application.

For example, the base is located on a supporting surface such as a floor or a table top, and the supporting shaft 121 is rotated in a supporting surface parallel to the floor or the table top.

When the support shafts 121 of the respective fans 11 are provided on the base 10, the support shafts 121 of the respective fans 11 may be provided on the base 10 vertically, or the support shafts 121 of the respective fans 11 may be provided on the base 10 obliquely, which is not limited in the embodiment of the present application.

When the support shafts 121 of the partial fans 11 are inclined on the base 10, the angles between the respective support shafts 121 inclined on the base 10 and the plane of the base 10 may be the same or different.

As is apparent from the above description, when the plurality of fans 11 included in the heat sink apparatus are disposed on the base, the heights of the respective fans 11 may be different.

Illustratively, fans 11 of different heights may be obtained by setting the support shaft 121 of each fan 11 to different lengths, or fans of different heights may be obtained by setting different inclinations to each fan 11.

When the support shaft 121 of the fan 11 rotates in the plane of the base 10, it may be rotated by a full rotation or by a predetermined angle.

Illustratively, the preset angle may be any one of 0 ° to 180 °.

For example, when the preset angle is 150 °, the rotation shaft may be rotated clockwise by 150 °, then rotated counterclockwise by 150 °, then rotated clockwise by 150 °, and the above process is repeated until the rotation shaft stops working.

Since the swing shaft 122 is mounted on the support shaft 121, when the support shaft 121 rotates in a horizontal plane where the base 10 is located, the swing shaft 122 can be driven to rotate in a plane parallel to the base 10. When the support shaft 121 rotates a full turn, the swing shaft 122 also rotates a full turn, and the support shaft 121 rotates a preset angle and the swing shaft 122 also rotates a preset angle.

The swing shaft 122 is movably connected to one end of the support shaft 121 far away from the base 10, and can swing on a plane perpendicular to the base 10, and the swing amplitude of the swing shaft 122 can be controlled as required.

Illustratively, the swing axle 122 may swing toward an end away from the base 10, or may swing toward an end closer to the base 10.

In one embodiment, one of the drive modules 12 further comprises:

a rotation shaft mounted on the swing shaft 122;

the impeller 111 is sleeved on the rotating shaft;

wherein the rotation plane of the rotation shaft is perpendicular to both the rotation plane of the support shaft 121 and the swing plane of the swing shaft 122.

Illustratively, the swinging shaft 122 may have a U-shaped structure, and the swinging shaft 122 is sleeved at an end of the supporting shaft 121 far from the base 10 through a concave surface of the U-shaped structure, and is capable of rotating in a plane perpendicular to the base 10 relative to an end of the supporting shaft 121.

Since the rotation shaft is mounted on the swing shaft 122 and the impeller 111 is sleeved on the rotation shaft, when the swing shaft 122 swings in a plane perpendicular to the base 10, the rotation shaft can be driven to swing in a plane perpendicular to the base 10, so that the impeller 111 is driven to swing in a direction perpendicular to the base 10.

Since the direction of the air outlet surface of the impeller 111 is different when the impeller 111 swings to different positions, that is, the direction of the air to be sent out is different, by controlling the swing direction and the swing amplitude of the swing shaft 122, the direction and the radiation range of the air to be sent out by the fan 11 on the plane perpendicular to the base 10 can be controlled.

Illustratively, when the swing shaft 122 swings toward an end away from the base 10, and swings to an angle of 45 ° with respect to the horizontal. At this time, the angle between the wind blown out from the fan and the horizontal plane is also about 45 °.

As is apparent from the above description, the rotation of the support shaft 121 may rotate the swing shaft 122 in a plane parallel to the base 10, and may rotate the impeller 111 in a plane parallel to the base 10, and based on this, the direction and the radiation range of the wind sent from the fan 11 in a plane parallel to the base 10 may be controlled by controlling the rotation direction and the rotation angle of the rotation shaft.

Illustratively, when the directions of the impellers of the adjacent one of the fans 11 in the heat dissipating apparatus are the same, the impellers of the two fans 11 may be controlled to be inclined toward one another by controlling the rotation of the support shaft 121 so that the ranges of the wind fields of the adjacent two fans overlap, and thus the wind fields of the two fans may be disturbed with each other.

Referring to fig. 4 to 6, in one embodiment, one of the driving modules 12 further includes: a first driving assembly mounted on the base 10 for driving the support shaft 121 to rotate with respect to the base 10;

a second driving assembly mounted on the support shaft 121 for driving the swing shaft 122 to rotate with respect to the support shaft 121;

and a third driving assembly mounted on the swing shaft 122 for driving the rotation shaft to rotate with respect to the swing shaft 122.

Referring to fig. 5 to 7, exemplarily, a first motor 124, a connection member 125, and a support bar 126; the first motor includes: a first fixed end 1241 and a first power output 1242;

the first fixed end 1241 is fixedly connected with the supporting shaft 121;

the first power output end 1242 is connected with the support rod 126 through a connecting piece 125;

the support bar 126 is fixed on the base 10;

the first motor 124 is configured to drive itself to rotate relative to the support rod 126 via the connection member 125.

Illustratively, the connector 125 described above includes: a first gear 1251 and a second gear 1252;

the first gear 1251 is fixedly connected with the first power output end 1242;

the second gear 1252 is fixed on the support bar 126 and is meshed with the first gear 1251;

the first motor 124 is configured to rotate the support shaft 121 by driving the first gear 1251 to rotate relative to the second gear 1252.

Wherein, the end of the support shaft 121 near the first motor 124 is provided with a connection post a, the first fixed end 1241 is provided with a connection lug b, and the first fixed end 1241 can be fixedly connected with the support shaft 121 by fixing the connection post a on the connection lug b. Based on this, when the first motor 124 rotates with respect to the support bar 126, the support shaft 121 may be driven to rotate.

The connecting member 125 may be a first gear 1251 and a second gear 1252 capable of being meshed with each other, and the first gear 1251 and the second gear 1252 each have a central hole. Based on this, the first power output end 1242 may be fixed in the central hole of the first gear 1251, the second gear 1252 is meshed with the first gear 1251, and the second gear 1252 is sleeved on the end of the support rod 126 away from the base 10 through the central hole.

Because the second gear 1252 is fixed on the support rod 126, the support rod 126 is fixed on the base 10, and therefore, the second gear 1252 is in a fixed state and cannot rotate under the driving of the first gear 1251, and when the first power output end 1242 rotates, the first gear 1251 can be driven to rotate around the second gear 1252, and the support shaft 121 can be driven to rotate around the support rod 126.

In another embodiment, the first power output 1242 may be directly fixed to the support rod 126, and the second gear may be fixed because the support rod is fixed. Thus, when the motor is in the working state, the first power output end can drive the first gear to rotate around the second gear, so as to drive the first fixed end 1241 and the supporting shaft 121 to rotate around the second gear.

Referring to fig. 4 to 6, illustratively, in order to increase the stability of the support shaft 121, the fixing assembly further includes: a bearing 127 and a bearing support 128;

the bearing bracket 128 is fixedly connected with one end of the supporting shaft 121 far away from the impeller 111;

the bearing 127 is disposed between the support rod 126 and the bearing support 128, and an outer ring of the bearing 127 is fixedly connected with the bearing support 128, and an inner ring of the bearing 127 is fixedly connected with the support rod 126.

As can be seen in fig. 7, the bearing support 128 is of an annular configuration, and has a first groove 1281 on an inner side of the annular configuration, an open end of the first groove 1281 facing the support bar 126.

The outer surface of the end of the support rod 126 near the second gear 1252 is provided with a first concave spigot 1261, the first end of the second gear 1252 which is opened into the support rod 126 is provided with a second concave spigot 1253, when the first gear 1251 is fixed on the support rod 126, the first concave spigot 1261 and the second concave spigot 1253 form a second groove, and the opening direction of the second groove is opposite to that of the first groove 1281.

The bearing 127 is fixed in an annular accommodating cavity formed by the first groove 1281 and the second groove, and an outer ring of the bearing 127 is fixedly connected with the inner surface of the bearing bracket 128, and an inner ring of the bearing 127 is fixedly connected with the outer surface of the supporting rod 126.

Illustratively, the outer ring of the bearing 127 may be adhered to the inner surface of the bearing support 128 by an adhesive, and the surface of the outer ring of the bearing 127 and the inner surface of the bearing support 128 may be provided with rough surfaces, so that the bearing support 128 drives the bearing outer ring to rotate by static friction between the inner ring of the bearing 127 and the inner surface of the bearing support 128 in the rotation process.

The connection manner between the inner ring of the bearing and the outer surface of the support rod 126 may refer to the connection manner between the outer ring of the bearing and the bearing support, and this embodiment will not be described herein.

Based on the above connection, when the first fixing end 1241 rotates around the supporting rod 126, the supporting shaft 121 and the bearing bracket 128 can be driven to rotate around the supporting rod 126.

In one embodiment, the end of the bearing support 128 near the supporting shaft 121 is further provided with an annular platform 1282, and the annular platform 1282 has a supporting effect on the first gear 1251, the second gear 1252 and the supporting shaft 121, so that the overall stability of the driving module 12 of the fan 11 can be further improved.

Referring to fig. 8, in one embodiment, the swing shaft 122: including a first side panel 1221, a second side panel 1222, and a bottom panel 1223;

the first side panel 1221 and the second side panel 1222 are perpendicular to the bottom panel 1223;

the swing shaft 122 is fixed to the third driving assembly through the bottom plate 1223, and is disposed on the support shaft 121 through the first side plate 1221 and the second side plate 1222;

the second drive assembly includes a second motor 129, the second motor 129 including: a second fixed end 1291 and a second power output end 1292;

the second fixed end 1291 is fixed on the support shaft 121, and the second power output end 1292 is connected to the first side plate 1221 or the second side plate 1222, for driving the swing shaft 122 to swing on a plane perpendicular to the base 10.

Based on the above connection, when the second motor 129 is in the working state, the second power output end 1292 rotates to drive the swinging shaft 122 to swing along the direction perpendicular to the base 10, and further drive the impeller to swing along the direction perpendicular to the base 10.

Referring to fig. 8, the third driving assembly illustratively includes a third motor 130, the third motor 130 being coupled to the rotation shaft 123 for driving the rotation shaft 123 to rotate with respect to the swing shaft 122.

For example, the third motor 130 includes a third fixed end fixedly connected to the bottom plate 1223 of the swing shaft 122 and a third power output end fixedly connected to the rotation shaft. Based on this, when the third motor 130 is in the working state, the third power output end rotates, and further drives the rotation shaft and the impeller to rotate.

It should be noted that the first motor 124, the second motor, and the third motor may be various types of rotating motors, such as a stepper motor.

In one embodiment, the heat dissipating device further comprises:

the control module is positioned in the base 10;

the control module is respectively connected with the driving modules 12 of the fans 11, and is used for controlling the wind fields of the fans 11 to at least partially overlap by controlling the working state of the driving modules 12 according to the working mode of the heat dissipation device.

As can be seen from the above description, the driving module 12 includes a first driving component, a second driving component and a third driving component, and the control module can control the rotation direction and the rotation angle of the supporting shaft 121 by controlling the first driving component, so as to control the wind field of the fan 11 on the plane parallel to the base.

The control module can also control the swinging direction and the swinging amplitude of the swinging shaft 122 by controlling the second driving component, so as to control the wind field of the fan 11 on the plane perpendicular to the base.

The control unit may also control the rotational speed of the rotation shaft by controlling the third driving unit, thereby achieving control of the wind speed of the fan 11.

For example, the control assembly may first obtain the power of each fan 11, the size of the impeller 111, the wind distance, and the orientation of the impeller 111 at the current time. Then, the radiation range of the wind field of each fan 11 is calculated according to the power of each fan 11, the size of the impeller 111, the wind distance and the direction of the impeller 111 at the current moment, and then the rotation direction, the swing amplitude and/or the wind speed of each fan 11 are adjusted according to the radiation range of the wind field of each fan 11, so that at least part of the wind fields of the fans 11 can interfere with each other.

For example, the included angle between the directions of the impellers of two adjacent fans 11 is controlled to be an acute angle, and if two fans 11 include an acute angle at any time of operation, wind fields of the two fans 11 at least partially overlap, so that turbulent flow that is disturbed by each other is formed.

In one embodiment, the heat dissipating device further comprises:

and the control module is arranged on the base.

The control module is respectively connected with the driving modules 12 of the fans and is used for controlling the wind fields of at least two fans to be at least partially overlapped by controlling the working state of the driving modules 12.

in this embodiment, as shown in fig. 2 and 3, by setting a plurality of fans 11 that form a certain angle with the vertical direction and the left-right direction of the plane in the plane, the rotational speed of the impeller 111 of each fan 11 may be independently controlled, so that the wind fields of the strokes of each fan 11 may be disturbed, thereby controlling the output wind sense of the whole heat dissipating device, and making the wind sense more similar to the sense of natural wind.

The rotation speed of each fan 11 can be controlled independently, each fan 11 has a separate wind speed curve, and the wind speed curves of the fans 11 are correlated as a whole.

The number of fans 11 is set to a minimum number of 2, and the upper limit of the number is not limited.

The angle between the fan 11 and the vertical plane in the horizontal and vertical directions may be fixed, or may be manually or electrically adjustable.

The wind fields of each fan 11 must form a certain mutual disturbing capacity instead of being operated individually.

All fans 11 are configured to rotate as a whole to increase the variety of the overall wind farm.

Illustratively, referring to fig. 9, the description is given taking the example in which two fans 11 interact with each other:

as shown in fig. 9, assuming that the angles between the fans 11 and the vertical plane in the horizontal and vertical directions may be set to be fixed, when the wind speed of the fans 11 is the same, when the direction of the wind sent by one fan 11 is A1 and the direction of the wind sent by the other fan 11 is A2, the wind fields of the two fans 11 are disturbed, and then the wind sent by the heat dissipating device is A3.

When the intensities A1 and A2 of the wind sent out by the two fans 11 are equal, the direction of the wind sent out by the heat sink is shown as a diagram in fig. 9. When the wind speeds of the two fans 11 are different, the directions of the wind sent by the heat dissipating device after the wind sent by the two fans 11 are disturbed are shown as b, c, d and d in fig. 9.

The structure of at least one fan 11 included in the heat dissipating apparatus is as follows:

the fixed end of the second motor is connected with the fixed frame through a screw, the fixed end of the second motor is fixed with the swinging shaft 122, but when the second motor rotating shaft rotates, the swinging shaft 122 rotates around the supporting shaft 121, so that the impeller 111 swings head up and down, and rotation control of the up and down positions of the impeller 111 is realized.

The implementation mode of the left and right shaking head is as follows: the first motor 124 is fixedly connected with the supporting shaft 121, the supporting shaft 121 is connected with a bearing bracket, and the bearing bracket is connected with the outer ring of the bearing.

The second-stage gear is fixed with the bearing inner ring and the supporting rod; the support bar is stationary relative to the ground so that the second gear is stationary relative to the ground, on which the teeth are arranged that cooperate with the first gear.

When the first power output end rotates to drive the primary gear to rotate, the primary gear drives the support shaft 121 and the bearing bracket connected with the primary gear to rotate around the center line of the second gear.
