It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known structures and processes have not been described in detail so as not to obscure the description of the application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
As shown in fig. 1, 2 and 3, an embodiment of the present application provides a heat dissipation module 100, including:
a first substrate 110, the first substrate 110 having a thickness direction;
the air suction fan 120 is disposed at intervals in the thickness direction between the air suction fan 120 and the first substrate 110, and defines an installation space;
the first diversion cooling fins 130 are disposed on the first substrate 110 at intervals along the rotation direction of the air suction fan 120, and are located in the installation space, so as to define a plurality of first diversion channels S1 extending along the radial direction of the air suction fan 120 in the installation space;
a plurality of second guiding fins 140, wherein the second guiding fins 140 are disposed on the first substrate 110 at intervals along the rotation direction of the air suction fan 120 and are located in the installation space, so as to define a plurality of second guiding channels S2 extending along the radial direction of the air suction fan 120 in the installation space; wherein, an end of each second guiding fin 140 away from the center of the first substrate 110 is located between two circumferentially adjacent first guiding fins 130.
In the technical solution of the embodiment of the present application, when the fan is started, the air flow flows in the first diversion channel S1 along the radial direction of the fan under the guidance of the first diversion heat sink 130, and the second diversion heat sink 140 has one end extending into the first diversion channel S1, so that the air flow can be split into two flows in the first diversion channel S1 and then flows along the radial direction of the fan under the guidance of the second diversion heat sink 140. Thus, in the heat dissipation module 100, the air flow flows in the radial direction of the fan. And the fan is disposed at one end of the first guide fins 130 and the second guide fins 140 away from the first substrate 110, when the fan is started, the air flows along the radial direction toward the center of the fan and also flows along the direction away from the first substrate 110, so that the hot air is more easily sucked out.
It should be noted that, the first substrate 110, the first guiding heat sink 130 and the second guiding heat sink 140 are all made of heat conductive materials; the first and second deflector fins 130 and 220 also exchange air flow with regular air flow to remove heat.
Further, it should be noted that, in the technical solution of the present application, generally, the first guide fins 130 are uniformly spaced, and the second guide fins 140 are uniformly spaced. Wherein the first guide fins 130 are farther from the axis of the fan than the second guide fins 140.
Further, in application, the first substrate 110 is disposed on an object to be heat-dissipated, such as the inverter 10. The suction fan 120 is disposed away from the housing of the inverter 10. The first and second guide fins 130 and 140 divide the space defined by the suction fan 120 and the first substrate 110 into a plurality of guide channels arranged radially. Heat on the inverter 10 is transferred to the first guide radiating fin 130 and the second guide radiating fin through the first substrate 110 by heat conduction; when the fan is started, air enters the first diversion channel S1 to fully exchange heat with the first diversion radiating fins 130, and then enters the second diversion channel S2 under the guidance of the second diversion radiating fins 140 to fully exchange heat with the second diversion radiating fins 140; meanwhile, the fan drives the air flow after heat exchange to blow out along the axial direction of the fan, so as to exchange heat with the inverter 10.
As an alternative implementation manner of the foregoing embodiment, as shown in fig. 1, in a radial direction of the air suction fan 120, an outer edge of the blade 121 of the air suction fan 120 extends out of an end of the second guiding fin 140 away from the center of the first substrate 110. That is, in the technical solution of the embodiment of the present application, the fan can completely cover the second guiding fin 140 in the projection plane in the thickness direction. In this structure, the caliber of the hot air discharge is larger, and the hot air discharge can completely cover the second diversion channel S2, so that the heat radiation air quantity is large enough.
In this structure, the first guide fins 130 mainly serve to guide the air flow radially, and the air flow exchanges heat with the first guide fins 130 while flowing in the first guide passage S1. The air after heat exchange enters the second diversion channel S2 to flow under the guidance of the second diversion radiating fin 140, and at the moment, the fan completely covers the second diversion radiating fin 140, and at the moment, the air flow flows along the radial direction of the fan (exchanges heat with the second diversion radiating fin 140) and flows along the axial direction of the fan (the air flow is sucked out), so that the heat exchange quantity can be increased, and the air output can be ensured.
In this embodiment, further, the outer edges of the blades 121 of the air suction fan 120 extend out of the end of the second guiding fin 140 away from the center of the first substrate 110, and are less than the middle of the first guiding fin 130. Namely: in the projection plane perpendicular to the thickness direction, the outer edge of the fan blade 121 is located between one end of the second guiding fin 140 away from the center of the first substrate 110 and the middle of the first guiding fin 130. In this structure, the heat exchange air volume of the heat radiation module 100 is large.
As an alternative implementation of the foregoing embodiment, as shown in fig. 2, the heat dissipation module 100 further includes a support plate 150, the support plate 150 and the first substrate 110 are disposed at intervals in the thickness direction, and the suction fan 120 is mounted on the support plate 150. In an embodiment, the support plate 150 is disposed at a central position of the heat dissipating module 100, which is generally disk-shaped and may be generally circular, square, or polygonal. The support plate 150 serves to fix the housing 300 of the fan such that there is an appropriate space between the fan and the first substrate 110. In general, the fan can be fixed to the support plate 150 by screws.
As an alternative to the above embodiment, the plurality of second guide fins 140 are connected to the support plate 150 at an end near the center of the first substrate 110. Typically, one end of the second guiding fin 140 is connected to the supporting plate 150, and extends radially outwards along the radial direction of the fan. The plurality of second guide fins 140 are disposed at an outer edge of the support plate 150 and circumferentially around the support plate 150. In this embodiment, the second flow guiding channel S2 can extend to the support plate 150, and the heat dissipating module 100 has a larger air output and heat exchanging capability.
As an alternative to the above embodiment, the plurality of second guide fins 140 define a cavity in the installation space; the heat dissipation module 100 further includes a support column 160, where the support column 160 is disposed in the cavity, and two opposite ends of the support column 160 are respectively connected to the support plate 150 and the first substrate 110. The support column 160 is disposed in the cavity, and the support column 160 is used for supporting the plate 150, improving stability of the plate 150. Typically, a plurality of second guide fins 140 are disposed around the support column 160 and spaced apart from the support column 160.
In order to reduce vibration and noise of the heat dissipation module 100 during operation, in the solution of the present application, as an alternative implementation of the foregoing embodiment, the center of the first substrate 110, the axis of the air suction fan 120, and the center of the support plate 150 are arranged in a collinear manner.
In the application process, the first guiding fin 130 is required to guide the external airflow into the heat dissipation module 100, and in order to improve the smoothness of the airflow, one end of the first guiding fin 130 away from the center of the first substrate 110 is located at the edge of the first substrate 110. That is, when the air flow enters the heat dissipation module 100, the air flow can flow along the radial direction, so that the streamline turbulence of the air flow in the heat dissipation module 100 is avoided, and the effects of reducing the wind resistance and improving the ventilation quantity can be achieved.
In addition, in application, the heat dissipation module 100 is generally disposed corresponding to a heating element of an object to be heat-dissipated. For example, when applied to the inverter 10, the heat dissipation module 100 is disposed corresponding to the power device in the inverter 10. And, further heat dissipation members 200 are provided on the case 300, and the heat dissipation members 200 are disposed at a relatively low temperature region, and the heat dissipation module 100 is disposed at a relatively high temperature region. The heat dissipation assembly 200 can be in butt joint with the heat dissipation module 100, so that when the fan is started, the heat dissipation assembly 200 can generate gas flow in the heat dissipation air channel S3 of the heat dissipation assembly 200 to exchange heat with the radiator. One end of the first guiding fin 130 away from the center of the first substrate 110 is located at the edge of the first substrate 110, that is, the air flow in the heat dissipating assembly 200 can flow directly along the first guiding channel S1 after passing through the heat dissipating air channel S3, and then is exhausted by the fan.
As shown in fig. 4, an embodiment of the present application further provides an inverter 10, which includes a housing 300, a heat dissipation assembly 200, and a heat dissipation module 100. The heat dissipation module 100 adopts some or all of the technical solutions of the foregoing embodiments, and thus the inverter 10 has some or all of the technical advantages of the foregoing embodiments. In an embodiment, the heat dissipating assembly 200 and the heat dissipating module 100 are both mounted on the housing 300. The heat dissipation assembly 200 defines an accommodating space and has a plurality of heat dissipation air channels S3 communicating with the accommodating space. The heat dissipation module 100 is disposed in the accommodating space, and the first substrate 110 is disposed on the housing 300; wherein, the adjacent plurality of heat dissipation air channels S3 are communicated with one of the plurality of first diversion channels S1.
In the technical scheme of the application, the heat dissipation module 100 is arranged in the accommodating space of the heat dissipation assembly 200, and the air in the heat dissipation assembly 200 is sucked out by the air suction fan 120 to generate air flow in the heat dissipation air channel S3; when the induced draft fan 120 is started, the heated air flow in the heat dissipation air channel S3 in the heat dissipation assembly 200 is sucked out by the induced draft fan 120 through the first diversion channel S1 and the second diversion channel S2, so as to dissipate heat of the inverter 10.
As an alternative to the above embodiment, as shown in fig. 5, the heat dissipation assembly 200 includes: a second substrate 210, the second substrate 210 being disposed on the housing 300, the second substrate 210 being connected to the first substrate 110; and a plurality of heat sinks 220, wherein the plurality of heat sinks 220 are arranged at intervals along the length direction or the width direction of the second substrate 210; the heat sink 220 is disposed obliquely to the first guiding heat sink 130, so that the heat dissipation air channel is obliquely communicated with the first guiding channel S1 correspondingly.
In an embodiment, the first substrate 110 is disposed at an edge of the second substrate 210 and extends away from the second substrate 210. The second substrate 210 is provided with a plurality of cooling fins 220, and the cooling fins 220 are arranged at intervals along the length direction or the width direction of the second substrate 210 to form a cooling air channel; these heat dissipation air channels are communicated with the first diversion channel S1. As shown in fig. 7, the fins 220 and the first guide fins 130 are inclined to each other, so that the airflow direction defined by the heat dissipation air channel intersects with the airflow direction defined by the first guide channel S1. In an embodiment, the first diversion channel S1 extends radially and has openings facing away from the first substrate 110, and the openings are disposed corresponding to the plurality of cooling air channels, so that the air flows in the plurality of adjacent cooling air channels can enter the first diversion channel S1 through the openings.
When the fan is started, the air enters the heat dissipation air channel S3 of the heat dissipation assembly 200, flows out of the heat dissipation air channel S3 after heat exchange of the heat dissipation assembly 200, enters the first flow guide channel S1, then enters the second flow guide channel S2, exchanges heat with the heat dissipation module 100, and is discharged by the fan.
As an alternative to the above embodiments, the inverter 10 further comprises a power device; the housing 300 defines a receiving cavity in which the power device is mounted; the heat dissipation module 100 is disposed corresponding to the power device. In the technical solution of the embodiment of the present application, the power device is a core functional device in the inverter 10, and is used for converting direct current into alternating current, and generating heat in the working process. Since the heat dissipation module 100 is mounted in the accommodating space defined by the heat dissipation assembly 200 on the housing 300, and the air suction fan 120 and the first substrate 110 of the heat dissipation assembly 200 are disposed at intervals in the thickness direction of the first substrate 110, the heat dissipation module 100 can be disposed corresponding to the power device, that is, in the relatively high temperature area of the inverter 10, and the air flow generated by the air suction fan 120 is mainly concentrated in the relatively high temperature area, which is beneficial to heat dissipation. The suction fan 120 is disposed at a distance from the housing 300 in the thickness direction, and sucks the air flow from the housing 300 to the outside. In this structure, in the case where the heat radiation amount of the inverter 10 can be increased, the layout space of the heat radiation module 200 and the heat radiation module 100 can also be reduced, and the size of the inverter 10 in the thickness direction can be reduced.
In the embodiment, as shown in fig. 4 and 6, the heat dissipation module 100 is provided in total of four, which are provided at the middle position of the inverter 10 case.
