With reference to fig. 1 to 5, a heat sink provided by the embodiment of the present disclosure includes a base 10, a blown plate 20, a first fin group 30, and a second fin group 40, where the base 10 is configured to be thermally connected to a frequency conversion module 200; the blowing plate 20 comprises an evaporation part 201 and a condensation part 202 which are bent and communicated, and the evaporation part 201 is in heat conduction connection with the base 10; the first fin group 30 is connected with the evaporation part 201 in a heat conduction way; the second fin group 40 is in heat conduction connection with the condensation part 202; wherein the surface where the fins 50 of the first fin group 30 are located intersects with the surface where the fins 50 of the second fin group 40 are located.

By adopting the radiator 100 provided by the embodiment of the disclosure, heat generated by the frequency conversion module 200 is transferred to the base 10 and is transferred to the evaporation part 201 of the inflation plate 20 through the base 10, and a heat transfer medium in the evaporation part 201 is heated to change phase and flows to the condensation part 202 to dissipate heat and reduce temperature; the heat of the evaporation part 201 and the condensation part 202 is respectively transferred to the first fin group 30 and the second fin group 40 for heat dissipation and cooling, and the heat dissipation efficiency of the radiator 100 is improved by phase change heat dissipation of a heat transfer medium and air cooling enhanced heat dissipation of the fin groups; in addition, the first fin group 30 is obliquely arranged relative to the second fin group 40, so that the distance between the first fin group 30 and the second fin group 40 can be enlarged, and the air cooling strengthening heat dissipation effect of the fin groups is improved; thereby improving the heat dissipation efficiency of the frequency conversion module 200.

The base 10 is connected with the frequency conversion module 200 in a heat conduction manner, for example, the base 10 is connected with the frequency conversion module 200 through a fastener; or, the frequency conversion module 200 is adhered to the surface of the base 10 by a heat-conducting silicon adhesive; or, the frequency conversion module 200 is welded on the base 10 to improve the heat transfer efficiency between the frequency conversion module 200 and the base 10.

The inside of the blowing plate 20 is filled with a heat transfer medium that can change phase. The heat generated from the inverter module 200 is transferred to the base 10, and the base 10 accumulates the heat and transfers the heat to the blowing plate 20. The susceptor 10 is thermally connected to the evaporation portion 201 of the blowing plate 20, and thus the heat transfer medium in the evaporation portion 201 is thermally phase-changed to a gaseous heat transfer medium and flows toward a low temperature region, i.e., toward the condensation portion 202.

The evaporation part 201 and the condensation part 202 are bent relatively, wherein the electric control box 60 for accommodating the frequency conversion module 200 is horizontally installed in the air conditioner outdoor unit, and the base 10 and the evaporation part 201 are also horizontally installed. Thus, the condensation portion 202 is bent to be opposed to the evaporation portion 201, and the condensation portion 202 is provided to be inclined upward from the evaporation portion 201 in order to facilitate the circulation flow of the heat medium. In this way, the heat in the evaporation portion 201 changes phase, and the heat transfer medium changed into the gaseous state moves upward along the condensation portion 202 until being condensed and changed into the liquid heat transfer medium. The liquid heat transfer medium is inclined upward relative to the evaporation portion 201 based on the condensation portion 202, so that the liquid heat transfer medium quickly flows back to the evaporation portion 201 under the action of gravity to perform the next heat dissipation cycle. Like this, not only through the heat transfer medium phase transition, with the heat take away evaporation portion 201 and base 10 fast, but also through the relative bending setting of evaporation portion 201 and condensation portion 202 for the time of liquid heat transfer medium backward flow, further accelerated heat dissipation cycle time, improved the radiating efficiency to base 10 and frequency conversion module 200.

The first fin group 30 is connected with the evaporation part 201 in a heat conduction mode, and the second fin group 40 is connected with the condensation part 202 in a heat conduction mode, so that under the condition that the heat transfer medium in the blowing plate 20 conducts heat in a phase change mode, heat is also transferred to the fin groups to conduct air cooling enhanced heat dissipation, and the heat dissipation efficiency of the base 10 and the frequency conversion module 200 is further improved.

Alternatively, the fins 50 of the first fin group 30 are perpendicular to the evaporation portion 201, and the fins 50 of the second fin group 40 are perpendicular to the condensation portion 202. The evaporation portion 201 and the condensation portion 202 are bent relatively, and then the first fin group 30 and the second fin group 40 are also disposed relatively obliquely, i.e. the surface where the fins 50 of the first fin group 30 are located intersects with the surface where the fins 50 of the second fin group 40 are located. In this way, the distance between the first fin group 30 and the second fin group 40 is increased, especially the distance on the heat dissipation side is increased, which is beneficial to quickly dissipating the heat transferred to the heat dissipation side by the first fin group 30 and the second fin group 40, and avoids relative interference and influence on the heat dissipation effect.

In practical applications, the heat conduction connection between the base 10 and the blowing plate 20, and the heat conduction connection between the blowing plate 20 and the fin group can refer to the heat conduction connection manner between the base 10 and the frequency conversion module 200, and will not be described herein again.

Alternatively, the relative inclination angle of the condensation portion 202 of the blow-up plate 20 to the evaporation portion 201 is greater than or equal to 3 °. In this way, the flow of the heat transfer medium in the expansion plate 20 is facilitated.

Optionally, the first fin group 30 is in thermally conductive contact with or spaced from the second fin group 40.

The first fin group 30 is in heat conductive contact with the second fin 50, that is, the first fin group 30 is in heat conductive contact with the second fin group 40 on the heat conductive side (the heat conductive connection side with the blow-up plate 20). In this way, when the heat transfer medium in the evaporation portion 201 is heated to change phase and transfer heat to the first fin group 30 and the condensation portion 202, the first fin group 30 is in heat-conducting contact with the second fin group 40, so that the heat of the first fin group 30 is transferred to the second fin group 40, and the heat dissipation efficiency of the first fin group 30 to the evaporation portion 201 is improved.

In addition, in the case that the first fin group 30 is in heat conduction contact with the second fin group 40, the first fin group 30 and the second fin group 40 may be an integrally molded structure. The fins 50 of the integrally formed fin groups may all be arranged in parallel. The specific sizes of the first fin group 30 and the second fin group 40 may be appropriately distributed according to the sizes of the evaporation portion 201 and the condensation portion 202 during the assembly with the blow-up plate 20. Based on the fin group, most of the fins 50 are of a sheet structure made of aluminum material, after distribution is completed, only the fins 50 belonging to the second fin group 40 need to be broken off, so that the second fin group 40 is obliquely arranged relative to the first fin group 30 and is synchronously obliquely arranged with the condensing part 202. Therefore, the fin group can be used for other radiators 100, the die is prevented from being reopened, the cost is reduced, and the application range of the fin group is widened.

In the case where the first fin group 30 and the second fin group 40 are disposed at an interval, the first fin group 30 and the second fin group 40 may be selected from specific installation positions of the evaporation portion 201 and the condensation portion 202 according to actual conditions, so as to improve the heat dissipation efficiency of the blowing plate 20.

Optionally, the first fin group 30 and/or the second fin group 40 includes a plurality of fins 50, the fins 50 including: the first bent portions 501 extend from the first edges of the fins 50 and are bent in the first direction, and the first bent portions 501 of the plurality of fins 50 are connected in sequence to form the heat dissipating surface 400.

The first bent portions 501 of the plurality of fins 50 are connected in sequence to form the heat dissipation surface 400. Thus, the surface of the fin group can be smooth, which is beneficial to the smooth appearance of the radiator 100, and the stability and firmness of the fin group can be improved.

The fin groups are connected by the first bent portions 501 of the plurality of fins 50, so that the distance between the adjacent fins 50 is adjustable, that is, the distance between the adjacent fins 50 is adjusted by adjusting the width of the first bent portions 501. Therefore, in the existing effective installation space, the distance between the fins 50 can be reduced, the number of the fins 50 can be increased, and the heat dissipation area 400 of the heat sink 100 can be increased. Compared with the existing aluminum extruded radiator 100, the embodiment can improve the overall heat transfer efficiency and the heat dissipation area 400 of the radiator 100 in the effective space without changing the overall volume of the radiator 100, thereby improving the overall heat exchange performance of the radiator 100 and effectively solving the heat dissipation problems of the base 10 and the frequency conversion module 200.

In the embodiment of the present disclosure, a plane of the first direction in which the fins 50 of the first fin group 30 are bent is parallel to the heat dissipation surface 400 of the first fin group 30, and a plane of the first direction in which the fins 50 of the second fin group 40 are bent is parallel to the heat dissipation surface 400 of the second fin group 40. In addition, the bending direction of the fins 50 of the first fin group 30 and the bending direction of the second fin group 40 are located on the same plane, but the directions may be the same or opposite.

Optionally, the heat dissipation surface 400 is configured with a plurality of openings 300 communicating with the gaps formed between adjacent fins 50, so that the airflow can cross and circulate between the gaps between adjacent fins 50 and the openings 300, thereby enlarging the circulation path of the airflow.

The air flow generated by the fan in the air conditioner outdoor unit flows through the first fin group 30 and the second fin group 40 to perform air cooling enhanced heat dissipation on the fin groups. The airflow passes through the gaps between adjacent fins 50, blowing heat from the fins 50 away from the fins 50. The plurality of openings 300 communicating with the gaps formed by the adjacent fins 50 are formed in the heat dissipation surface 400 of the fin group, so that when the air flow passes through the gaps of the adjacent fins 50, the air flow can not only flow in from one side of the gap and then flow out from the other side, but also flow in from one side of the gap and flow out from the communicating openings 300, or the air flow can also flow in from the openings 300 to the gaps and flow out from one side of the gap. Thus, the airflow is crossed and circulated in the gaps between the adjacent fins 50 and the openings 300, so that the circulation path of the airflow is enlarged, the heat can be blown away from the fin group as fast as possible, and the heat dissipation effect of the fin group is improved.

The opening 300 may be in the shape of a window on the heat dissipating surface 400. As shown in fig. 3.

Optionally, the fin 50 further comprises: a second bent part 502 bent and extended from a second edge of the fin 50 along a first direction, the second bent parts 502 of the plurality of fins 50 being sequentially connected to form a heat conducting surface 500; wherein the second edge is opposite to the first edge, and the heat conducting surface 500 is connected with the inflation plate 20 in a heat conducting manner to dissipate heat transferred by the inflation plate 20.

The second bent portions 502 of the plurality of fins 50 are connected in sequence, and thus the heat conductive surface 500 is formed. In this way, when the fin group is thermally connected to the inflation plate 20, on the one hand, the heat transfer area between the fin group and the inflation plate 20 can be increased, and on the other hand, the connection stability between the adjacent fins 50 of the fin group and the inflation plate 20 can be improved.

Optionally, the width of the second bent part 502 is the same as the width of the first bent part 501.

Optionally, the distance from the heat conduction surface 500 of the first fin group 30 to the heat dissipation surface 400 is greater than the distance from the heat conduction surface 500 of the second fin group 40 to the heat dissipation surface 400.

The distance from the heat conduction surface 500 to the heat dissipation surface 400 of the first fin group 30 is greater than the distance from the heat conduction surface 500 to the heat dissipation surface 400 of the second fin group 40, i.e., the size of the first fin group 30 is greater than the size of the second fin group 40. Therefore, when the heat sink 100 is installed in the electronic control box 60 and is integrally installed with the electronic control box 60 in the outdoor unit of the air conditioner, the size of the second fin group 40 is reduced, and the second fin group can be prevented from being obliquely arranged to cause interference with the adjacent fan bracket 70 or the fan, thereby affecting the normal use of the outdoor unit of the air conditioner.

Optionally, the minimum distance of the second fin group 40 to the fan support 70 is greater than or equal to 10mm, so that the second fin group 40 is kept at a safe distance from the fan support 70.

Optionally, the inflation panel 20 further comprises: the first edge 203 is formed by bending and extending from the edge of the condensation part 202, and the first edge 203 is arranged in parallel with the evaporation part 201 so as to be connected with the transversely arranged electric control box 60.

The heat sink 100 is detachably connected to the electronic control box 60 through the first edge 203 of the blow-up plate 20, so that the heat sink 100 and the electronic control box 60 are assembled. The evaporation portion 201 is horizontally arranged in the transverse direction, so that the first edge 203 is parallel to the evaporation portion 201, on one hand, the radiator 100 and the electronic control box 60 can be stably assembled, and on the other hand, the radiator 100 is uniformly stressed after being assembled. Secondly, it also facilitates the processing of the electrical control box 60.

In addition, there is no flow channel in the first edge 203, and no heat transfer medium flows in the first edge 203.

Optionally, first rim 203 is configured with mounting holes 207 for detachable connection with electrical control box 60.

Optionally, the inflation panel 20 further comprises: the second edge 204 is formed by bending and extending from the edge of the evaporation portion 201 multiple times to overlap the electronic control box 60.

The second edge 204 and the first edge 203 are two edges opposite to the blow-up plate 20. The heat sink 100 helps to evenly stress the blow-up plate 20 by overlapping the second edge 204 of the blow-up plate 20 to the electronic control box 60.

Likewise, there is no flow channel in the second rim 204 and no heat transfer medium flows in the second rim 204.

The second edge 204 is formed by bending and extending from the edge of the evaporation portion 201 multiple times, for example, in an inverted L-shaped structure, as shown in fig. 1 and 2. In this way, the blow-up panel 20 overlaps the folded edge 602 of the electrical box 60 via the second rim 204, which helps to improve the stability of the connection.

Optionally, the second rim 204 includes a first bent section 205 bent from an edge of the evaporation portion 201 and a second bent section 206 bent from an edge of the first bent section 205. Preferably, the evaporation portion 201 is disposed perpendicular to the first bending section 205, and the first bending section 205 is disposed perpendicular to the second bending section 206.

In practice, the second bent segment 206 of the second edge 204 is overlapped on the folded edge 602 of the electronic control box 60, and the first bent segment 205 abuts against the side of the folded edge 602. Thus, external moisture can be blocked from entering the electrical control box 60 by the second rim 204.

Wherein the thickness of the base 10 preferably corresponds to the width of the first bend segment 205. When the base 10 is connected to the evaporation portion 201 in a heat conducting manner, the heat absorbing surface of the base 10 and the upper surface of the second bending section 206 are facilitated to be located on the same plane, so as to be connected to the electronic control board of the electronic control box 60 and the frequency conversion module 200, and interference is prevented; but also can make the appearance of the heat sink 100 neat.

When assembling the base 10 and the blow-up plate 20, the base 10 may be abutted against the first bent section 205, which facilitates accurate positioning of the base 10. The assembly efficiency is improved.

Referring to fig. 1 to 7, an outdoor unit of an air conditioner according to an embodiment of the present disclosure includes an electric control box 60 and a heat sink 100 provided in the above embodiment; the bottom of the electronic control box 60 is configured with a hollow portion 601, the heat sink 100 is inserted into the hollow portion 601, and the edge of the inflation plate 20 is overlapped with the folded edge 602 of the electronic control box 60 at the hollow portion 601.

The heat sink 100 is disposed through the hollow portion 601, and the edge of the inflation board 20 is overlapped on the side of the electronic control box 60 at the hollow portion 601, so that the inflation board 20 and the base 10 are located in the electronic control box 60, and the first fin group 30 and the second fin group 40 are exposed outside the electronic control box 60. Like this, not only help first fin group 30 and second fin group 40 to carry out the forced air cooling and strengthen the heat dissipation, but also can transmit the external environment of automatically controlled box 60 from the internal environment of automatically controlled box 60 with the heat that frequency conversion module 200 produced through radiator 100 to the cooling of externally dispelling the heat has reduced the inside ambient temperature of automatically controlled box 60, further promotes the cooling effect to frequency conversion module 200.

The border of inflation board 20 laps in automatically controlled box 60 hem 602 in fretwork portion 601 department, and can dismantle with hem 602 and be connected to guarantee the stability of radiator 100 in packing, transportation and use, thereby guaranteed the stability of the frequency conversion module 200 of being connected with radiator 100 heat conduction, in case frequency conversion module 200 receives unnecessary damage, and then influences the normal work of air conditioner.

Alternatively, in the case where the radiator 100 is provided in the electronic control box 60, the condensation portion 202 of the blow-up plate 20 is disposed obliquely upward from the evaporation portion 201; the second fin group 40 is disposed opposite to a fan of the outdoor unit of the air conditioner, and the second fin group 40 is disposed obliquely upward, so that the airflow can flow into the gap between the adjacent fins 50 from the opening 300 of the second fin group 40.

Thus, the condensation portion 202 of the blowing plate 20 and the second fin group 40 are disposed near the fan side. The heat transfer medium in the evaporation portion 201 moves to the condensation portion 202 after being heated and phase-changed, and is cooled by heat dissipation through the second fin group 40. The condensing portion 202 and the second fin group 40 are disposed near one side of the fan, air flow generated by the fan performs air cooling enhanced heat dissipation on the second fin group 40, and the gaseous heat transfer medium is condensed and cooled in the condensing portion 202 to become a liquid heat transfer medium. Because the condensing portion 202 is disposed to be inclined upward from the evaporating portion 201, the liquid heat transfer medium in the condensing portion 202 flows back to the evaporating portion 201 by gravity, and the next heat dissipation cycle is performed.

The second fin group 40 is arranged obliquely upwards, so that airflow can flow into the gap between adjacent fins 50 from the opening 300 of the heat dissipation surface 400 of the second fin group 40, and the airflow can directly flow to the fins 50 of the second fin group 40 away from the fan side and the first fin group 30 along the heat dissipation surface 400, thereby improving the heat dissipation effect of air cooling enhanced heat dissipation of the fin groups.

Optionally, a waterproof gasket is disposed between the edge of the inflation plate 20 and the edge of the hollow portion 601 to prevent water vapor in the external environment from entering the electronic control box 60 from the hollow portion 601.

By arranging the waterproof sealing gasket between the edge of the blowing plate 20 and the edge of the hollow part 601, water vapor carried in air flow blown out by the fan can be prevented from entering the electric control box 60 from the hollow part 601, so that electronic elements in the electric control box 60, such as the electric control plate, the frequency conversion module 200 and the like are corroded, and the service life of the outdoor unit of the air conditioner is influenced.
