With reference to fig. 1 to 4, the present disclosure provides a heat sink, which includes a base 10, a blowing plate 20, and a heat dissipation element, wherein the base 10 is configured to be thermally connected to a frequency conversion module 40 to receive heat generated by the frequency conversion module 40; the blowing plate 20 comprises an evaporation part 201 and a condensation part 202 which are vertical and communicated, and the evaporation part 201 is in heat conduction connection with the base 10; the heat dissipation element comprises a plurality of fin groups 30 which are connected with the inflation plate 20 in a heat conduction mode so as to dissipate heat and cool the inflation plate 20; wherein, evaporation portion 201 and/or condensation portion 202 are provided with a plurality of fin group 30 that set up at intervals.
By adopting the radiator provided by the embodiment of the disclosure, heat generated by the frequency conversion module 40 is transferred to the base 10 and transferred to the evaporation part 201 of the inflation plate 20 through the base 10, 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 evaporation part 201 and the condensation part 202 are vertically arranged, so that the heat transfer medium can circularly flow in the evaporation part 201 and the condensation part 202, in addition, the fin group 30 is connected to the inflation plate 20 in a heat conduction manner, and the heat dissipation area of the inflation plate 20 is enlarged; the fin groups 30 are arranged at intervals in the evaporation part 201 and/or the condensation part 202, so that the attenuation degree of the air flow is reduced, the air flow can flow into the fin groups 30 from the interval space of the adjacent fin groups 30 to increase the disturbed flow, and the heat exchange effect is improved; the phase change heat transfer of the heat transfer medium and the air cooling enhanced heat dissipation of the heat dissipation element are realized, and the heat dissipation efficiency of the heat radiator is improved.
The base 10 is connected with the frequency conversion module 40 in a heat conduction mode, and the frequency conversion module 40 is tightly attached to the surface of the base 10 so as to improve the heat transfer efficiency of the base 10 and the frequency conversion module. The base 10 and the frequency conversion module 40 can be connected through a fastener; or, the frequency conversion module 40 is adhered to the surface of the base 10 by a heat-conducting silicon glue; alternatively, other auxiliary heat-conducting filling materials, such as heat-conducting fins, are disposed between the frequency conversion module 40 and the base 10 to improve the heat transfer efficiency between the frequency conversion module 40 and the base 10.
Similarly, the connection between the base 10 and the evaporation portion 201 and the connection between the heat dissipation element and the inflation plate 20 can be referred to as the connection between the base 10 and the frequency conversion module 40, so as to improve the heat transfer efficiency between the base 10 and the evaporation portion 201 and between the heat dissipation element and the inflation plate 20.
As shown in fig. 1 to 3, the evaporation unit 201 includes two fin groups 30, and the two fin groups 30 are spaced apart from each other by a predetermined distance. The condenser 202 is provided with two fin groups 30, and the two fin groups 30 are also spaced apart by a predetermined distance. The pitch between the two fin groups 30 in the evaporation unit 201 may be the same as or different from the pitch between the two fin groups 30 in the condensation unit 202.
The radiator is arranged on the outdoor unit of the air conditioner, and the air flow generated by the fan flows through the radiating element to perform air cooling enhanced radiation. The airflow flows through the gaps between the adjacent fins 301 in the fin group 30, exchanges heat with the fins 301, and then carries heat to blow out of the fin group 30, so as to achieve the purposes of heat dissipation and cooling.
A group of fin groups 30 are arranged at the evaporation part 201 and the condensation part 202, and the fins 301 of the fin groups 30 are too long, so that airflow is subjected to wind resistance in gaps between adjacent fins 301, wind power and wind speed are attenuated, heat cannot be blown out of the fin groups 30 in time, and the heat dissipation effect is poor.
The fins 30 on the evaporation part 201 and the condensation part 202 are arranged at intervals, so that the length of the fins 301 is shortened, the influence of wind resistance on the air flow is reduced, the air flow is mixed with the external air flow in the interval space of the adjacent fins 30 after flowing through one fin group 30, the turbulent flow is increased, the air speed is improved, the air flow continuously flows through the other fin group 30, the heat is timely blown out of the heat dissipation element and the evaporation part 201 and/or the condensation part 202, the heat exchange effect of the air flow and the radiator is enhanced, and the heat dissipation efficiency of the radiator is further improved.
The fin group 30 includes a plurality of fins 301. The heat of the evaporation part 201 and the condensation part 202 is transferred to the fins 301, air cooling strengthening heat dissipation is carried out, the heat dissipation area of the heat sink is enlarged through the fins 301, and the heat dissipation efficiency of the heat sink is improved, so that the heat dissipation efficiency of the frequency conversion module 40 is improved, and the heat dissipation problem of large heat flow density and large power is effectively solved.
The blowing plate 20 is filled with a phase-changeable heat transfer medium. The heat generated from the inverter module 40 is transferred to the base 10, and the base 10 has a certain thickness to accumulate the heat and transfer the accumulated heat to the blowing plate 20. The susceptor 10 is thermally connected to the evaporation portion 201 of the blowing plate 20, so that 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 electronic control box 50 accommodating the inverter module 40 is horizontally installed in the air conditioner outdoor unit, and the base 10 and the evaporation portion 201 are also horizontally installed, so that the evaporation portion 201 is vertically arranged with the condensation portion 202. Thus, the evaporation portion 201 is heated to change phase, and the heat transfer medium changed into gaseous state moves upwards, i.e. moves upwards along the condensation portion 202 while dissipating heat and reducing temperature until being condensed into liquid heat transfer medium. The liquid heat transfer medium rapidly 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 fast take away from evaporation portion 201 and base 10, but also through evaporation portion 201 and the perpendicular setting of condensing part 202 for the time of liquid heat transfer medium backward flow, further accelerated the heat dissipation cycle time, improved the radiating efficiency to base 10 and frequency conversion module 40.
Optionally, the blow-up plate 20 further comprises: the connection portion 203, which has an arc-shaped structure, connects the evaporation portion 201 and the condensation portion 202 to guide the heat transfer medium in the blowing plate 20.
The arc-shaped connecting portion 203 connects the evaporation portion 201 and the condensation portion 202, and guides the heat transfer medium in the blowing plate 20, so that the heat transfer medium flows more smoothly at the connecting portion of the evaporation portion 201 and the condensation portion 202, and the flow resistance is reduced.
As shown in conjunction with fig. 1 and 2, the connection portion 203 includes a horizontal section connected to the evaporation portion 201 and a vertical end connected to the condensation portion 202. In this way, the heat transfer medium smoothly transitions between the evaporation portion 201 and the connection portion 203 and between the connection portion 203 and the condensation portion 202.
Optionally, the blow-up plate 20 is of unitary construction. Thus, leakage at the joint between the evaporation unit 201, the connection unit 203, and the condensation unit 202 can be avoided.
Optionally, the connection part 203 is configured with a drain hole 204 near the edge of the evaporation part 201 or the connection of the connection part 203 and the evaporation part 201 to drain accumulated water.
The evaporation part 201 is horizontally arranged, and the connecting part 203 is bent upwards from the edge of the evaporation part 201, so that water is easy to accumulate at the connecting part of the connecting part 203 and the evaporation part 201, and the accumulated water is drained out of the blowing plate 20 in time through the structure of the drain hole 204.
The drain hole 204 may be located at an edge of the evaporation portion 201, or a connection portion 203 and the evaporation portion 201, so as to smoothly drain the accumulated water.
Alternatively, there are a plurality of drainage holes 204, and the distance between adjacent drainage holes 204 may be equal or unequal.
In addition, the drain hole 204 is provided at a position to avoid a flow passage through which the heat transfer medium flows in the expansion plate 20, thereby preventing the heat transfer medium from leaking.
Optionally, the blow-up plate 20 further comprises: an inner surface 205, which is attached to the base 10 for heat conduction; and, an outer surface 206, in heat-conducting engagement with the fin pack 30; the heat of the base 10 is transferred to the inner surface 205 of the inflation plate 20, is phase-changed by the heat transfer medium in the inflation plate 20, is transferred to the outer surface 206 and the fin group 30, and is dissipated and cooled by the fin group 30. As shown in connection with fig. 3.
In the case where the base 10 is located on the inner surface 205 of the blowing plate 20 and the fin group 30 is located on the outer surface 206 of the blowing plate 20, the fin group 30 may be disposed corresponding to the base 10 or may be disposed at a different position. Alternatively, the heat sink includes both the fin group 30 disposed corresponding to the base 10 and the fin group 30 disposed in a staggered manner.
Optionally, the fin group 30 comprises a plurality of fins 301, the fins 301 being perpendicular to the outer surface 206 of the blowing plate 20 where they correspond.
The fins 301 are perpendicular to the outer surface 206 of the corresponding blow-up plate 20, so that the heat dissipation area of the heat sink can be enlarged by the plurality of fins 301, and the heat dissipation is enhanced by air cooling through the fins 301, thereby improving the heat dissipation efficiency of the heat sink.
The fins 301 are perpendicular to the outer surface 206 of the corresponding blowing plate 20, it being understood that the fins 301 are only arranged perpendicular to the blowing plate 20 in the area of the thermally conductive connection to enlarge the heat dissipation area of that area of the blowing plate 20.
Optionally, the fin 301 comprises: a first bent portion 302 bent and extended from a first edge of the fin 301 in a first direction, and connected to an adjacent fin 301 in the same fin group 30 to form a heat conduction surface; wherein the heat conducting surface is attached to the outer surface 206 of the blowing plate 20 to enlarge the heat transfer area between the fin group 30 and the blowing plate 20. As shown in connection with fig. 3.
The plurality of fins 301 in the same fin group 30 are connected in sequence by first bent portions 302, and are configured to form a heat transfer surface. In this way, when the fin group 30 and the blow plate 20 are thermally connected, on the one hand, the heat transfer area between the fin group 30 and the blow plate 20 can be increased, and on the other hand, the connection stability between the adjacent fins 301 of the fin group 30 and between the fin group 30 and the blow plate 20 can be improved.
Optionally, the fin 301 further comprises: the second bent portion 303 is bent and extended from the second edge of the fin 301 along the first direction, and is connected to the adjacent fin 301 in the same fin group 30 to form a heat dissipation surface, which is helpful for improving the connection stability of the adjacent fins 301 in the fin group 30.
Optionally, the fin set 30 has an opening on the heat dissipation surface, so that the heat dissipation surface has an opening window structure. In this way, the way of the airflow flowing into the fin group 30 can be increased, and the turbulent flow can be increased, so that the wind speed is increased, the heat is quickly blown away from the fin group 30, and the heat dissipation effect of the fin group 30 is improved.
Alternatively, the first direction is parallel to the surface of the blowing plate 20 where the fin group 30 is correspondingly disposed. Thus, after the heat-conducting surface is attached to the inflation plate 20, the fins 301 of the fin group 30 are perpendicular to the inflation plate 20 in the corresponding region.
Alternatively, the size of the fin group 30 located in the evaporation portion 201 and the size of the fin group 30 located in the condensation portion 202 may be the same or different. The specific size is determined according to the sizes of the evaporation part 201 and the condensation part 202. However, the plurality of fin groups 30 located in the evaporation portion 201 are the same in size and are symmetrically disposed. Thus, it is helpful to make the evaporating part 201 uniformly stressed. Similarly, the plurality of fin groups 30 located in the condensation portion 202 are the same in size and are symmetrically arranged. Thereby making the condensing portion 202 uniformly stressed and ensuring the structural strength of the blowing plate 20.
Optionally, the base 10 comprises: the first base body 101 is in heat conduction connection with the frequency conversion module 40; a second base 102 formed in a protruding configuration from a surface of the first base 101, and thermally connected to the inflation plate 20; the area of the second substrate 102 is smaller than that of the first substrate 101. As shown in connection with fig. 4.
The first substrate 101 and the second substrate 102 are integrally formed. The first base 101 is thermally connected to the heat conducting module, so that the first base 101 is located on the upper portion of the second base 10 after the base 10 is mounted to the frequency conversion module 40. The frequency conversion module 40, the first base 101, the second base 102 and the inflation plate 20 are arranged in sequence from top to bottom. The second base 102 is formed by a protruding structure from the surface of the first base 101, and the area of the board surface of the second base 102 is smaller than that of the board surface of the first base 101, so that when the base 10 is installed on the electronic control box 50, the first base 10 can be lapped on the electronic control box 50 for installation and fixation.
The heat generated by the frequency conversion module 40 is transferred to the first base 101, transferred to the second base 102 through the first base 101, transferred to the inflation plate 20, and transferred to the fin group 30 for heat dissipation and temperature reduction through phase change of a heat transfer medium in the inflation plate 20.
Alternatively, the plate surface area of the first base 101 is smaller than the plate surface area of the evaporation portion 201.
The area of the first base 101 is smaller than that of the evaporation portion 201, so that the heat transferred from the first base 101 to the evaporation portion 201 via the second base 102 can be dissipated and cooled by the evaporation portion 201 with a larger size. In addition, in the case of assembling the base 10 and the inflation plate 20, four corner regions of the base 10 may be detachably coupled to the inflation plate 20 by bolts to improve the coupling firmness of the base 10 and the inflation plate 20.
Alternatively, the evaporation unit 201 and the condensation unit 202 are each configured with a mounting hole 207 to be detachably coupled to the electrical control box 50 of the outdoor unit of the air conditioner.
The evaporation part 201 and the condensation part 202 are respectively provided with the mounting hole 207, the evaporation part 201 and the condensation part 202 are detachably mounted on the electric control box 50 of the outdoor unit of the air conditioner by penetrating the mounting hole 207 through bolts, and thus, the firmness of connection between the expansion plate 20 and the electric control box 50 can be ensured.
Optionally, the mounting holes 207 are preferably formed in four corner regions of the evaporation portion 201 and the condensation portion 202, so as to ensure the connection stability between the blowing board 20 and the electrical control box 50, and prevent the blowing board 20 from being locally stressed unevenly and the structural strength from being weakened.
Alternatively, the mounting hole 207 may be shared by the regions where the evaporation portion 201 and the condensation portion 202 are close to each other. That is, the mounting holes 207 are provided in the four corner regions of the inflation panel 20 and the regions where the evaporation portion 201 and the condensation portion 202 are close to each other. Like this, reduce the processing cost on the one hand, on the other hand can reduce the bolt of a certain quantity, improves assembly efficiency.
