Wherein, the mounting portion 4012 and the inflation portion 4011 are an integrally formed structure.

In addition, in practical application, the mounting portion 4012 is detachably connected to the fin heat dissipation element by inserting a fastener into the mounting hole 4018. Wherein the fastener can be a screw or a bolt. In addition, the mounting portion 4012 includes a plurality of mounting holes 4018.

The first avoiding portion 4013 and the second avoiding portion 4014 are provided with threaded holes 4019 to which fasteners, such as screws or bolts, can be mounted. The first bypass 4013 and the second bypass 4014 can be beneficial to prevent the fastener from penetrating the heat transfer circuit 4015 of the blow-up portion 4011, so that the connection between the fastener and the blow-up plate 401 is leaked.

Alternatively, the threaded hole 4019 may be a through hole or a blind hole. Wherein, the through-hole or blind hole all set up the screw thread to with threaded fastener threaded connection.

Optionally, the finned heat sink element comprises a base 402 and fins 403, the base 402 comprising opposing first and second surfaces 4021, the first surface of the base 402 being in thermally conductive connection with a heat dissipating surface of the inflation 4011, the area of the heat dissipating surface being less than or equal to the area of the first surface; a plurality of fins 403, at least some of the fins 403 being vertically and thermally coupled to the second surface 4021 of the base 402; wherein the base 402 is integrally formed with the fins 403.

By adopting the radiator provided by the embodiment of the disclosure, the heat absorption surface of the blowing plate 401 of the radiator receives heat, the heat transfer working medium in the blowing plate 401 is heated and changes phase, the heat of the heat absorption surface is transferred to the heat dissipation surface, the heat is transferred to the first surface of the base 402 and the fins 403 through the heat dissipation surface, and the heat is dissipated and cooled through the fins 403, so that the temperature uniformity and the heat dissipation efficiency of the whole radiator are improved, the purpose of efficient heat dissipation of the radiator on the frequency conversion module 30 under a high-temperature working condition is realized, and the refrigeration effect of the air conditioner under the high-temperature working condition is ensured.

The inflation plate 401 may be welded to the base 402. Like this, not only can realize being connected between inflation board 401 and the base 402 fixedly, but also be favorable to improving base 402 and inflation board 401's laminating degree to improve the heat transfer efficiency between base 402 and the inflation board 401, so that the heat of inflation board 401 cooling surface transmits to base 402 fast. Optionally, the inflation plate 401 and the base 402 are bonded by coating a heat conductive silicone. Optionally, a heat conducting sheet may be further disposed between the inflation plate 401 and the base 402 to improve the heat transfer efficiency between the inflation plate 401 and the base 402.

Optionally, the base 402 may be made of aluminum, which improves the heat conduction efficiency with the inflation plate 401, and further facilitates the improvement of the heat dissipation efficiency of the inverter module 30. In practical application, the base 402 has a certain thickness, and thus, can accept the heat of the heat dissipation surface of the inflation board 401 and store heat, and cool down the inflation board 401, so that the inflation board 401 can dissipate heat and cool down the frequency conversion module 30.

The heat radiation area of the heat radiation surface of the inflation plate 401 is smaller than or equal to the area of the first surface of the base 402. Therefore, the heat of the heat dissipation surface of the inflation plate 401 can be quickly transferred to the base 402, and the heat conduction efficiency of the base 402 and the inflation plate 401 is improved.

A plurality of fins 403 are vertically and thermally coupled to the second surface 4021 of the base 402. The heat transferred by the base 402 can be quickly dispersed by the plurality of fins 403, which is helpful for enlarging the heat dissipation area of the heat sink and improving the heat dissipation efficiency of the heat sink. In practical applications, the plurality of fins 403 are evenly spaced on the second surface 4021 of the base 402. The heat is transferred to the base 402 through the inflation plate 401, the base 402 stores heat and transfers the heat to each fin 403, and the airflow flows through the fins 403 to perform air cooling heat dissipation, so that the heat dissipation efficiency of the heat sink is improved.

Further, since the base 402 and the fins 403 are integrally molded, thermal resistance is small, and heat transfer efficiency between the base 402 and the fins 403 can be further improved.

Optionally, the fins 403 are welded to the base 402. Therefore, the stability of connection between the fins 403 and the base 402 is improved, and the stability of the fins 403 in the air cooling heat dissipation process is further improved. Optionally, the fins 403 are bonded to the base 402 by a thermally conductive silicone adhesive. This helps to improve the heat transfer efficiency between the fins 403 and the base 402.

Optionally, the fins 403 of the finned heat sink element are parallel to the axis of the fan.

Under the driving of the rotation of the fan, the intake airflow of the outdoor unit of the air conditioner enters from the bottom of the gap between adjacent fins 403, flows through the surface of the fins 403 and then flows out from the top of the gap, blows heat away from the fins 403, and cools the fins 403 by air cooling. The fins 403 of the heat sink are parallel to the axis of the fan, that is, the fins 403 are perpendicular to the plane of the fan 10, so that the airflow flows through the fins 403 of the heat sink under the action of the fan 10 and makes full contact with the surface of each fin 403, thereby improving the heat dissipation efficiency of the fins 403.

Optionally, the fins 403 of the heat sink are located directly below the fan 10. Thus, the air-cooling heat dissipation effect of the airflow on the fins 403 can be improved, the heat dissipation efficiency of the heat sink is improved, and the heat dissipation effect of the heat sink on the frequency conversion module 30 is further improved.

Optionally, the blowing section 4011 is configured with a heat transfer circuit 4015, the heat transfer circuit 4015 flows through at least the heat absorbing surface and the heat dissipating surface, and the heat transfer circuit 4015 is filled with a heat transfer medium.

The heat transfer circuit 4015 of the blowing plate 401 provided by the embodiment of the disclosure is internally vacuumized and filled with heat transfer working medium, the integrally formed blowing plate 401 has few welding points, the risk of leakage of the heat transfer working medium is reduced, the cost of the radiator is reduced, and the reliability of the radiator is improved in the packaging, transportation and working processes of the radiator or an air conditioner outdoor unit.

Alternatively, the heat transfer medium may be a phase-changeable heat transfer medium, such as a heat transfer medium that can change phase between a gaseous state and a liquid state. The liquid working medium on the heat absorption surface is heated, becomes gaseous after the temperature rises, and is diffused to the heat dissipation surface, the gaseous working medium exchanges heat with the base 402 on the heat dissipation surface to dissipate heat, and becomes liquid after the temperature drops, and the next heat dissipation cycle is carried out. Optionally, the heat transfer medium is a refrigerant.

Here, "the heat transfer circuit 4015 flows at least through the heat absorbing surface and the heat radiating surface" can be understood as: the heat absorbing surface of the inflation plate 401 is provided with a heat transfer circuit 4015, or the heat radiating surface of the inflation plate 401 is provided with the heat transfer circuit 4015, or the heat absorbing surface and the heat radiating surface of the inflation plate 401 are both provided with the heat transfer circuits 4015 which are communicated with each other.

Optionally, the heat dissipating surface is convex provided with the heat transfer circuit 4015, and/or the heat absorbing surface is planar.

Here, "the heat radiating surface of the inflation plate 401 is convex" can be understood as: the area of the heat dissipation surface where the heat transfer circuit 4015 is formed protrudes from the area of the heat dissipation surface where the heat transfer circuit 4015 is not formed, and the heat dissipation surface is uneven. Under the condition that the blowing plate 401 is in heat conduction connection with the base 402, the heat transfer efficiency of the blowing plate 401 and the base 402 can be improved through the heat transfer working medium filled in the heat transfer loop 4015 in the heat dissipation surface of the blowing plate 401. Wherein, the heat absorbing surface of the inflation plate 401 is not constructed with the heat transfer circuit 4015, and the heat absorbing surface is a plane.

When the heat dissipation surface is a convex surface provided with the heat transfer circuit 4015, the base 402 is connected with the heat dissipation surface in a heat conduction manner, wherein when the base 402 is welded with the heat dissipation surface or bonded through heat conductive silica gel, solder or the heat conductive silica gel is filled in an area where the heat dissipation surface is not provided with the heat transfer circuit 4015. In this way, the heat dissipation surface is arranged in a convex structure, so that not only can the heat dissipation area of the heat dissipation surface be enlarged, but also the actual heat transfer area between the heat dissipation surface and the base 402 can be increased, and further the heat transfer efficiency of the inflation plate 401 and the heat dissipation efficiency of the frequency conversion module 30 are increased.

Under the condition that the heat absorbing surface is a plane, the heat absorbing surface of the blowing plate 401 is connected with the frequency conversion module 30, which is beneficial to improving the stability of the connection between the blowing plate 401 and the frequency conversion module 30.

Optionally, the blow-up plate 401 is provided with a set of nip points for configuring the heat transfer circuit 4015; the rolling point group at least comprises a first row of rolling points and a second row of rolling points which are adjacent, and the rolling points in the first row of rolling points and the rolling points in the second row of rolling points are arranged in a staggered mode.

The rolling point group comprises a plurality of rolling points 4016, a micro-flow path is formed between adjacent rolling points, and the plurality of micro-flow paths are communicated with each other to form a heat transfer loop 4015. The plurality of microchannels not only increase the flow path of the heat transfer working medium, but also provide a plurality of flow directions for the heat transfer working medium. In practical application, the heat transfer working medium is guided by the micro flow path to circularly flow in the heat transfer loop 4015 until being heated and phase-changed, so that the liquid heat transfer working medium can flow to the region with higher heat productivity of the frequency conversion module 30, and the heat dissipation effect of the region with higher heat productivity of the frequency conversion module 30 is improved. Meanwhile, the overall heat dissipation effect of the frequency conversion module 30 is improved.

The rolling points in the first row of rolling points and the rolling points in the second row of rolling points are arranged in a staggered mode, so that the heat transfer medium can be guided, the phenomenon that the local micro flow path of the blowing and expanding plate 401 is too few is avoided, the heat transfer efficiency is reduced, and local overheating is caused. The liquid heat transfer working medium is continuously dispersed to the periphery under the drainage of the micro-channel between the rolling points to carry out heat exchange until the liquid heat transfer working medium is vaporized into the gaseous heat transfer working medium.

Optionally, a plurality of rolling points in the first row of rolling points are arranged at equal intervals. A plurality of rolling points in the second row of rolling points are uniformly arranged at intervals. Therefore, the flow of the heat transfer working medium is facilitated, and the heat transfer working medium is uniformly distributed. The liquid heat transfer working medium and the frequency conversion module 30 carry out sufficient heat exchange, the local overheating phenomenon can be eliminated to the maximum extent, the temperature of the frequency conversion module 30 is reduced, and the refrigerating or heating effect of the air conditioner is improved.

The number and the row number of the rolling points in the rolling point group are not limited in the embodiment of the disclosure. If the rolling point group comprises M rows of rolling points, any one row of rolling points comprises N rolling points, wherein M is larger than 2, and N is larger than 2.

In addition, in practical applications, the size of the rolling point 4016 can be selected according to practical requirements. The shape of the rolling point can also be selected according to actual requirements.

Optionally, as shown in fig. 2 and fig. 3, the inflation plate 401 further includes a heat transfer working medium filling port 4017, and the heat transfer working medium filling port 4017 is in on-off communication with the heat transfer circuit 4015.

Through the heat transfer working medium filling port 4017, not only the heat transfer loop 4015 can be vacuumized, but also the heat transfer working medium can be filled into the heat transfer loop 4015.

Under the condition that the heat dissipation surface is provided with the heat transfer loop 4015, the heat dissipation surface of the inflation plate 401 where the heat transfer working medium pouring port 4017 is located is a plane and is lower than the convex surface of the heat dissipation surface provided with the heat transfer loop 4015.

Optionally, heat transfer medium inlet 4017 is flat, and the flat plane is parallel to the plane of fins 403. In practical application, the heat transfer working medium filling opening 4017 is flat, and the flow area of the heat transfer working medium filling opening 4017 is smaller than the minimum flow area in the heat transfer loop 4015, so that the heat transfer working medium in the heat transfer loop 4015 can be prevented from leaking out of the heat transfer working medium filling opening 4017. In addition, in the case of the radiator being installed, the heat transfer working medium pouring port 4017 is located at the side of the expansion plate 401. Thus, the risk of leakage increase due to the fact that liquid heat transfer medium accumulates at the bottom of the expansion plate 401 and gaseous heat transfer medium accumulates at the top of the expansion plate 401 can be reduced.
