[0031] In the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0032] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] Please refer to Figures 1 to 6 , the utility model provides a phase change heat sink, comprising a fin group 1, a connecting plate 2 and a first pressure riveting stud 3;

[0034] The fin group 1 is arranged on one side of the connecting plate 2, and the first self-clinching stud 3 is arranged on the other side of the connecting plate 2, and the first self-clinching stud 3 is used to be fixedly connected to the external heat dissipation element;

[0035] The connecting plate 2 is provided with a plurality of hollow channels 21 along the Y-axis direction, and a heat transfer medium is provided in the hollow channels 21 .

[0036] A hollow channel 21 filled with a heat transfer medium is provided in the connecting plate 2 of the phase change radiator. When the heat transfer medium is heated, it absorbs heat and evaporates into gas, and rises to the top of the hollow channel 21. Then, the heat transfer medium releases heat, transfers heat to the outside through the fin group 1 and the connecting plate 2, and the heat transfer medium changes phase back to liquid and flows back to the bottom of the radiator.

[0037] The phase-change heat sink utilizes phase-change heat transfer through the heat transfer medium and enhanced heat dissipation through air cooling of the fin assembly 1, thereby improving the heat dissipation efficiency of the phase-change heat sink. Furthermore, the connecting plate 2 is provided with a first self-clinching stud 3, which directly connects to the external heat dissipation element. This simplifies the number of components and assembly, reduces the difficulty of assembling and disassembling the electronically controlled heat sink, improves production efficiency, and facilitates subsequent maintenance.

[0038] A screw hole is provided in the first self-clinching stud 3 , and the phase change heat sink and the external heat dissipation element are fixed by threaded connection between the screw and the first self-clinching stud 3 .

[0039] Specifically, the fin group 1 includes a plurality of fins 11 , and the plurality of fins 11 are respectively vertically arranged on the connecting plate 2 .

[0040] In practical applications, a phase-change heat sink is installed in an air conditioner's outdoor unit to dissipate heat for its electronically controlled components. The airflow generated by the unit's fan flows through fin assembly 1, providing enhanced cooling. The airflow flows through the gaps between adjacent fins 11 in fin assembly 1, exchanging heat with them before being blown out of fin assembly 1, carrying the heat with it.

[0041] The fins 11 are vertically arranged on the connecting plate 2. The above structure is conducive to the airflow flowing through the spaces between adjacent fins 11, which helps to reduce the attenuation of the airflow and thus improve the heat exchange effect.

[0042] Specifically, the fins 11 are arranged side by side at intervals along the X-axis direction.

[0043] In a specific embodiment of the present invention, the fins 11 are spaced and arranged side by side along the X-axis. Because the phase-change heat sink is located in the air conditioner outdoor unit, and the air cooling process of the existing air conditioner outdoor unit is: entering the air conditioner outdoor unit from the side wall and being discharged from the top of the air conditioner outdoor unit; therefore, the fins 11 are spaced and arranged side by side along the X-axis to match the air flow direction. This prevents the fins 11 from interfering with the air flow and generating turbulence, which would affect the heat dissipation efficiency of the air conditioner outdoor unit and cause differences in the heat dissipation effect of each fin 11, thereby affecting the heat dissipation effect of the phase-change heat sink.

[0044] Specifically, the fin 11 includes a fin body 111 and a reinforcing plate 112;

[0045] One end of the fin body 111 is connected to the connecting plate 2 , one end of the reinforcing plate 112 is connected to the proximal end of the other end of the fin body 111 , and the other end of the reinforcing plate 112 is tightly against the side wall of the other fin body 111 .

[0046] The above structure, connected to the adjacent fin bodies 111 via the reinforcing plate 112, can serve as structural reinforcement, provide additional support, and improve the strength and stability of the fin assembly 1. In addition, the reinforcing plate 112 can conduct heat to the adjacent fins 11, so that the entire fin assembly 1 dissipates heat evenly, improving the heat dissipation effect.

[0047] Optionally, the connecting plate 2 is made of aluminum alloy. Since aluminum alloy has a high thermal conductivity, using aluminum alloy as the material of the connecting plate 2 can effectively conduct heat and help quickly dissipate heat.

[0048] The utility model also provides an electric control installation structure, which is applied to an air conditioner outdoor unit, and includes an electric control installation plate 4, an electric control main board 5 and the above-mentioned phase change radiator;

[0049] The electric control mounting plate 4 is provided with a through hole 41, the fin group 1 passes through the through hole 41, and the connecting plate 2 is detachably connected to the outer edge of the through hole 41; the electric control main board 5 is detachably connected to the connecting plate 2 through the first riveted stud 3; the electric control mounting plate 4 is installed on one side of the box body of the air conditioner outdoor unit.

[0050] The electronic control mounting structure is applied to an air conditioner outdoor unit and utilizes the aforementioned phase change heat sink for heat dissipation, thereby improving the heat dissipation effect of the electronic control mainboard 5. Furthermore, the connecting plate 2 is provided with a first self-clinching stud 3, which is directly connected to the electronic control mainboard 5 via the first self-clinching stud 3. This simplifies the number of components and assembly, reduces the difficulty of assembling and disassembling the electronic control heat sink, improves production efficiency, and facilitates subsequent maintenance.

[0051] Furthermore, the electronic control main board 5 includes a main board PCB board 51 and a main board module 52; the main board PCB board 51 is provided with electronic control components on the side facing away from the phase change radiator, and the main board module 52 is arranged on the side facing the phase change radiator of the main board PCB board 51; the main board module 52 is detachably connected to the connecting board 2.

[0052] In one embodiment of the present invention, motherboard module 52 is an IGBT electronic control module, a component that generates a large amount of heat. Placing motherboard module 52 toward and in direct contact with the phase-change heat sink enhances overall heat dissipation. Motherboard PCB 51 connects motherboard module 52 with other electronic control components, achieving electrical connection and signal transmission.

[0053] Furthermore, the phase change heat sink is also provided with a second pressure riveted stud 6, which is arranged on one side of the connecting plate 2; the main board PCB board 51 is provided with an avoidance hole 510 adapted to the position of the second pressure riveted stud 6, and the main board module 52 is provided with a connection hole 520 adapted to the position of the avoidance hole 510. The phase change heat sink and the main board module 52 are detachably connected through the cooperation of screws, the connection hole 520 and the second pressure riveted stud 6.

[0054] With this structure, the mainboard PCB 51 and the mainboard module 52 can be securely connected to the phase-change heat sink via the second self-clinching stud 6. The screws also transfer heat, thereby improving the heat dissipation effect. The second self-clinching stud 6 has screw holes. During assembly, the screws are sequentially passed through the avoidance hole 510 and the connection hole 520, and then threadedly connected to the second self-clinching stud 6.

[0055] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such equivalent variations or substitutions are encompassed within the scope of the claims of this application.
