[0041] At present, in the related technologies of micro inverters, micro inverters can be used in outdoor, balcony, RV and other scenes to realize the conversion of AC and DC. For example, one end of the micro inverter can be connected to the photovoltaic panel and the other end can be connected to the energy storage power supply, so that the photovoltaic panel charges the energy storage power supply. However, when the micro inverter is working, a lot of heat will be generated, which will cause the surface temperature of the micro inverter shell to rise. When the user touches the shell of the micro inverter, it is easy to cause a hot feeling, affecting the user experience. In addition, the temperature increase may also cause the micro inverter to have over-temperature frequency reduction protection, affecting the power generation of the photovoltaic panel.

[0042] In view of this, the present application provides a heat sink and inverter combination device capable of dissipating heat from an inverter. The heat sink is used to dissipate heat from the inverter, and the heat sink includes a main body and a fan. The main body is provided with a accommodating cavity and a first air outlet and a second air outlet connected to the accommodating cavity. The accommodating cavity passes through the main body and forms an opening, and the opening is configured to allow at least part of the inverter to enter and exit the accommodating cavity. The fan is provided in the main body, and the fan is configured to supply air to the first air outlet or to exhaust air from the first air outlet. When the accommodating cavity accommodates at least part of the inverter, the part of the accommodating cavity between the main body and the inverter forms an air duct, and the fan generates airflow in the air duct when supplying or exhausting air, and the air duct is configured to allow the airflow to flow through the outer surface of the inverter.

[0043] When the heat sink provided by the present application is in use, at least part of the inverter is accommodated in the accommodating cavity, and the part of the accommodating cavity between the main body and the inverter forms an air duct. After the fan supplies air, an airflow is generated in the air duct that flows in from the first air outlet and flows out from the second air outlet, or an airflow is generated that flows in from the second air outlet and flows out from the first air outlet. The airflow will flow through the outer surface of part of the inverter, thereby dissipating the heat of the inverter, and the orderly flowing airflow in the air duct can effectively take away the heat of the inverter, with high heat dissipation efficiency, thereby effectively reducing the temperature of the inverter and avoiding the scalding sensation. At the same time, it can reduce the possibility of over-temperature and frequency reduction protection of the inverter, and ensure that the inverter continues to operate at a higher power; on the other hand, the radiator is detachably connected to the inverter through the accommodating cavity. When the inverter needs to dissipate heat, the radiator and the inverter can be installed to achieve heat dissipation. When heat dissipation is not required, the radiator and the inverter can be disassembled, so as not to change the volume of the inverter, which is more convenient to adapt to various scenarios and improve the user experience.

[0044] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0045] like Figures 1 to 3As shown, an embodiment of the present application provides a heat sink 100 and an inverter assembly device 200. The inverter assembly device 200 includes an inverter 201 and a heat sink 100. The inverter 201 generates heat during operation, and the heat sink 100 is used to dissipate heat from the inverter 201.

[0046] Inverter 201 can be used in scenes such as outdoor, balcony or RV, and the use scene can be changed according to the user's use needs. Inverter 201 can be a unidirectional inverter or a bidirectional inverter. For example, inverter 201 can be electrically connected between a photovoltaic device and a load, an energy storage power supply or a power grid, and inverter 201 can convert the direct current generated by the photovoltaic device into alternating current for use by the load or the power grid; for example, inverter 201 can be electrically connected between the power grid and the energy storage power supply, and inverter 201 can convert the alternating current of the power grid into direct current to charge the energy storage power supply, and can also convert the direct current in the energy storage power supply into alternating current and transmit it to the power grid. Among them, as an illustrative example, the energy storage power supply can be a portable power supply used in outdoor scenes or a home energy storage system for home energy storage; the load can be an air conditioner, a refrigerator, a mobile phone, other energy storage devices or other electrical equipment, etc.; the photovoltaic device can be a solar panel, etc.

[0047] like Figure 3 , Figure 5 and Figure 8 As shown, in some embodiments, the heat sink 100 includes a main body 10, and the main body 10 is provided with a receiving cavity 11, and the receiving cavity 11 passes through one side of the main body 10 and forms an opening 14, and the opening 14 is used for at least part of the inverter 201 to enter and exit the receiving cavity 11, so that the inverter 201 can be detachably installed on the heat sink 100. When the inverter 201 is installed on the heat sink 100, the inverter 201 is at least partially located in the receiving cavity 11, and when the inverter 201 is removed from the heat sink 100, the inverter 201 leaves the receiving cavity 11. The heat sink 100 is detachably connected to the inverter 201 through the receiving cavity 11. When the inverter 201 needs to dissipate heat, the heat sink 100 and the inverter 201 can be installed to achieve heat dissipation, and when heat dissipation is not required, the heat sink 100 and the inverter 201 can be disassembled, so as not to increase the volume of the inverter 201, and it is more convenient to adapt to various scenarios and improve the use experience.

[0048] In some embodiments, the heat sink 100 further includes a fan 20, which is disposed in the main body 10. The main body 10 is further provided with a first air port 12 and a second air port 13 that are connected to the accommodating chamber 11. The fan 20 is used to supply air to the first air port 12 or to extract air from the first air port 12. When the accommodating chamber 11 accommodates at least part of the inverter 201, the portion of the accommodating chamber 11 between the main body 10 and the inverter 201 forms an air duct 111. When the fan 20 is a hair dryer, the fan 20 is used to supply air to the first air port 12. When the fan 20 supplies air, it can generate an airflow in the air duct 111 that enters from the first air port 12 and exits from the second air port 13. When the fan 20 is an exhaust fan, the fan 20 is used to exhaust air toward the first air outlet 12. When the fan 20 exhausts air, it can generate an airflow in the air duct 111 that enters from the second air outlet 13 and exits from the first air outlet 12. The air duct 111 can allow the airflow to flow through the outer surface of the inverter 201, thereby dissipating heat from the inverter 201 to reduce the temperature of the inverter 201, improve the operating stability of the inverter 201, and reduce the hot feeling when the user touches the inverter 201. At the same time, it can reduce the possibility of over-temperature and frequency reduction protection of the inverter, thereby ensuring that the inverter continues to operate at a higher power.

[0049] In some embodiments, the main body 10 includes a surrounding wall 15 and a bottom wall 16, the surrounding wall 15 is arranged around the bottom wall 16, the accommodating chamber 11 is formed between the surrounding wall 15 and the bottom wall 16, the second air outlet 13 is arranged on the surrounding wall 15, and the first air outlet 12 is arranged on the bottom wall 16. When the accommodating chamber 11 accommodates at least part of the inverter 201, since the bottom wall 16 faces the inverter 201 and the surrounding wall 15 surrounds the inverter 201, the first air outlet 12 is arranged facing the inverter 201, so preferably, the fan 20 supplies air to the first air outlet 12, so that the airflow flows toward the outer surface of the inverter 201 and then flows out from the second air outlet 13, so that the airflow flows through the outer surface of the inverter 201 more fully, thereby maximizing the heat taken away from the inverter 201.

[0050] In some embodiments, the bottom wall 16 has a first surface 161 and a second surface 162 connected to each other, the first surface 161 and the second surface 162 are both located in the flow channel 111, the plane where the first surface 161 is located is perpendicular to the surrounding wall 15, the first surface 161 is closer to the opening 14 relative to the bottom of the surrounding wall 15, and the first air outlet 12 is provided on the first surface 161. The second surface 162 is connected between the first surface 161 and the surrounding wall 15, the second surface 162 is inclined from the first surface 161 to the bottom of the surrounding wall 15, and the surrounding wall 15 is provided with a second air outlet 13 at a position facing the second surface 162. The first surface 161 is used to make the first air outlet 12 face the inverter 201, and the inclined second surface 162 is used to guide the airflow in the flow channel 111 to flow out from the second air outlet 13 or guide the airflow in the flow channel 111 to flow into the first air outlet 12, and the cross-sectional area of ​​the flow channel 111 gradually increases toward the second air outlet 13, thereby increasing the airflow rate in the flow channel 111, and further improving the heat dissipation efficiency of the inverter 201.

[0051] In some embodiments, there are two second surfaces 162, and the two second surfaces 162 are respectively arranged on opposite sides of the first surface 161. There are at least two second air outlets 13, and a second air outlet 13 is arranged on the surrounding wall 15 at a position facing each second surface 162, so that the first air outlet 12 is connected to the second air outlet 13 on opposite sides of the flow channel 111, so that the airflow in the flow channel 111 can flow on opposite sides of the first air outlet 12, thereby increasing the area of ​​the airflow in the flow channel 111 flowing through the outer surface of the inverter 201, so as to improve the heat dissipation efficiency of the inverter 201, and also make the flow of the airflow more uniform, so that the heat dissipation of the inverter 201 is more uniform, so as to achieve a uniform temperature effect. Further optionally, the second surface 162 can also have three or four or more, and can be distributed on the required side of the first surface 161 according to the shape of the first surface 161, thereby further increasing the area of ​​the airflow passing through the outer surface of the inverter 201, and further improving the uniformity of the airflow, thereby improving the heat dissipation efficiency and temperature equalization effect of the inverter 201; or, all four sides of the first surface 161 are connected to the second surface 162, so that the airflow in the flow channel 111 can flow along any radial direction of the first air outlet 12, so that the airflow can flow through the entire lower surface of the inverter 201, so as to improve the heat dissipation efficiency and temperature equalization effect of the inverter 201.

[0052] In some embodiments, the main body 10 is provided with a limiting surface 17 in the accommodating cavity 11, and the limiting surface 17 is closer to the opening 14 than the first air outlet 12, that is, the limiting surface 17 is closer to the opening 14 than the first surface 161. When the accommodating cavity 11 accommodates at least part of the inverter 201, the limiting surface 17 is used to contact the inverter 201 to limit the depth of the inverter 201 entering the accommodating cavity 11, to ensure that there is a gap between the inverter 201 and the first air outlet 12, to prevent the inverter 201 from blocking the first air outlet 12, and to ensure that the flow channel 111 is unobstructed. Figure 6 , Figure 8 and Fig. 9As shown, in some embodiments, the heat sink 100 further includes a temperature measuring component 30, which is disposed on the limiting surface 17. When the accommodating cavity 11 accommodates at least part of the inverter 201, the temperature measuring component 30 is used to contact the inverter 201 to measure the temperature of the inverter 201, thereby detecting the temperature of the inverter 201 in real time. The temperature measuring component 30 is electrically connected to the control board 90 in the heat sink 100, and the control board 90 is electrically connected to the fan 20. The control board 90 adjusts the wind speed of the fan 20 according to the temperature value detected by the temperature measuring component 30. For example, when the temperature measuring component 30 detects that the temperature value is higher than a certain threshold, it means that the inverter 201 is under high load and the surface temperature is high. The control board 90 will control the fan 20 to increase the speed to increase the heat dissipation efficiency of the inverter 201. Or for example, when the temperature measuring component 30 detects that the temperature value is lower than another threshold value, it means that the inverter 201 is under low load and the surface temperature is low. The control board 90 will control the fan 20 to reduce the speed to achieve a silent effect and reduce energy consumption.

[0053] In some embodiments, the temperature measuring component 30 includes an elastic member 31, a temperature sensor 32 and a heat conductive sheet 33. The limiting surface 17 is provided with a mounting groove 171. The elastic member 31 is disposed in the mounting groove 171. The temperature sensor 32 is located in the mounting groove 171 and is abutted against the elastic member 31. The heat conductive sheet 33 is thermally connected to the side of the temperature sensor 32 away from the elastic member 31. The heat conductive sheet 33 is partially exposed from the mounting groove 171 and is higher than the limiting surface 17. The heat conductive sheet 33 is used to fit the outer surface of the inverter 201. When the accommodating cavity 11 accommodates at least part of the inverter 201, the inverter 201 contacts the limiting surface 17 and presses down the heat conductive sheet 33, so that the elastic member 31 is pressurized and applies force to the temperature sensor 32 toward the inverter 201, so that the heat conductive sheet 33 is closely attached to the outer surface of the inverter 201. The heat conductive sheet 33 transfers the heat of the inverter 201 to the temperature sensor 32 through its own thermal conductivity, so that the temperature sensor 32 detects the temperature of the inverter 201; when the inverter 201 leaves the accommodating cavity 11, the elastic member 31 deforms and returns to a natural state to reset the heat conductive sheet 33.

[0054] In some embodiments, the temperature measuring component 30 further includes a thermally conductive adhesive 34, which is disposed between the temperature sensor 32 and the thermally conductive sheet 33. The thermally conductive adhesive 34 is used to fix the temperature sensor 32 and the thermally conductive sheet 33 to prevent the temperature sensor 32 from being separated from the thermally conductive sheet 33 and becoming ineffective. As an illustrative example, the temperature sensor 32 is a NTC (Negative Temperature Coefficient) temperature probe.

[0055] In some embodiments, the heat conductive sheet 33 is provided with a hook 331, and the main body 10 is provided with a avoidance groove 172 outside the installation groove 171. The hook 331 can be slidably disposed in the avoidance groove 172, and can engage with the main body 10 during the process of sliding away from the elastic member 31 to fix the heat conductive sheet 33 and the main body 10 to prevent the heat conductive sheet 33 from detaching.

[0056] like Figure 7 and Figure 8 As shown, in some embodiments, the heat sink 100 further includes a bottom shell 40, the bottom shell 40 is connected to the side of the main body 10 facing away from the accommodating cavity 11, a fan cavity 41 is formed between the bottom shell 40 and the main body 10, the fan 20 is arranged in the fan cavity 41, and the bottom shell 40 and the main body 10 are used to fix and protect the fan 20. Further optionally, the height H of the fan cavity 41 can be adjusted according to actual conditions to increase or decrease the distance between the first surface 161 and the outer surface of the inverter 201, thereby adaptively improving the heat dissipation efficiency of the inverter 201.

[0057] In some embodiments, a third air port 42 is provided on a side of the bottom shell 40 facing away from the main body 10, and the third air port 42 is connected to the first air port 12, and the third air port 42 can be directly opposite to the first air port 12. When the fan 20 supplies air to the first air port 12, the fan 20 inhales air from the third air port 42; when the fan 20 draws air from the first air port 12, the fan 20 exhausts air from the third air port 42.

[0058] In some embodiments, a plurality of protrusions 43 are further provided on the side of the bottom shell 40 facing away from the main body 10, and a gap 44 connected to the third air outlet 42 is formed between the plurality of protrusions 43. When the side of the bottom shell 40 facing away from the main body 10 needs to be placed on a plane or needs to be attached to a wall, the gap 44 can connect the third air outlet 42 with the outside to ensure that the third air outlet 42 is not blocked, thereby allowing the flow channel 111 to be unobstructed.

[0059] like Figure 3 , Figure 4 and Figure 7 As shown, in some embodiments, the radiator 100 further includes a wall-mounted plate 50, a first fixing member 60 and a second fixing member 70. The wall-mounted plate 50 is detachably mounted on the side of the bottom shell 40 facing away from the main body 10. The wall-mounted plate 50, the main body 10, the bottom shell 40 and the inverter 201 are provided with aligned through holes 80. The first fixing member 60 is used to pass through the through holes 80 to fix the wall-mounted plate 50, the main body 10 and the bottom shell 40. The second fixing member 70 is used to fix the wall-mounted plate 50 to the wall. As an exemplary example, the first fixing member 60 and the second fixing member 70 are both screws.

[0060] like Figure 8As shown, in some embodiments, a battery (not shown) is provided inside the radiator 100 to power the fan 20, the temperature measuring component 30 and the control board 90, or the radiator 100 needs to be connected to an external power supply to power the fan 20, the temperature measuring component 30 and the control board 90.

[0061] In some embodiments, a button 101 is further provided on the outer surface of the radiator 100 . The button 101 is electrically connected to the control board 90 , and the fan 20 can be turned on and off by the button 101 .

[0062] In some embodiments, the surrounding wall 15 is provided with a card slot (not shown), and the side wall of the inverter 201 is provided with a buckle (not shown), and when the inverter 201 and the heat sink 100 are installed, the card slot and the buckle are engaged to fix the inverter 201 and the heat sink 100. It is understandable that the card slot can also be provided on the inverter 201, and the buckle can also be provided on the surrounding wall 15.

[0063] In some embodiments, the surrounding wall 15 surrounds the inverter 201, and the inverter 201 only contacts and cooperates with the surrounding wall 15 and the limiting surface 17, and there is no snap fit. When in use, the inverter 201 is directly placed flat on the limiting surface 17, and the heat sink 100 can be used to dissipate heat from the inverter 201, and the inverter 201 can be directly picked up to separate the inverter 201 from the heat sink 100, which is easier and faster to operate.

[0064] like Figures 1 to 4 As shown, in some embodiments, since the inverter 201 generates a large amount of heat when working, and the shell of the inverter 201 is usually made of metal, the temperature of the shell of the inverter 201 can reach a high temperature of 70-80 degrees. When the inverter 201 needs to be moved or transported, if the user touches the inverter 201, it will cause the user to feel uncomfortable due to the scalding, which affects the use. Therefore, the inverter combination device 200 also includes a heat insulation cover 202, which is detachably installed on the side of the inverter 201 facing away from the radiator 100. The heat insulation cover 202 is used to cover at least part of the outer surface of the inverter 201 and play a heat insulation role to prevent the user from accidentally touching the inverter device 200 and getting burned.

[0065] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
