Description

Technical Field

[0001] This utility model relates to the field of inverter technology, and in particular to an inverter with heat dissipation function. Background Technology

[0002] In current inverter designs, the boost inductor and inverter inductor are key components, responsible for voltage boosting and DC-to-AC conversion, respectively. However, with the increasing power density of power electronic devices and the diversification of application scenarios, the thermal management of these inductors under different operating conditions has become particularly prominent. Traditionally, inverters use a fixed heat dissipation structure to handle the heat generated by the inductors. However, due to the significant differences in losses between the boost inductor and inverter inductor under various operating conditions, uneven heat generation occurs. This imbalance not only causes certain inductors to overheat, increasing the risk of localized overheating, but also limits the efficiency and adaptability of the overall system's heat dissipation structure.

[0003] Specifically, under high load or frequent temperature fluctuations, the temperature difference between the two inductors may further intensify, creating a high-temperature point for a single inductor. This not only affects the reliability and lifespan of the inductor itself but may also adversely impact the overall performance of the inverter. Utility Model Content

[0004] Based on this, this utility model provides an inverter with heat dissipation function to solve the problem of local overheating of inductor temperature limiting the efficiency and adaptability of the entire system's heat dissipation structure.

[0005] This utility model provides an inverter with heat dissipation function, including:

[0006] The inverter body, inductor box, heat sink, and fan are provided. The inductor box is located at the bottom of the inverter body, and the heat sink is also located at the bottom of the inverter body, with the heat sink located on one side of the inductor box. The fan is located at one end of the inductor box and the heat sink.

[0007] The inductor box contains an inductor.

[0008] The inductor includes a boost inductor and an inverter inductor. The inverter inductor is located at one end of the inductor box near the fan, and the boost inductor is located at the other end of the inductor box.

[0009] The inductor has an inner core.

[0010] The inner core is equipped with a heat pipe.

[0011] The space between the heat pipe and the inner core is filled with insulating thermally conductive adhesive, and the gap between the inductor and the inductor box is also filled with insulating thermally conductive adhesive.

[0012] The inductor box is provided with heat dissipation fins on its exterior.

[0013] The heat dissipation teeth are one of the following: fin-shaped, needle-shaped, wavy, and plate-shaped.

[0014] Beneficial effects: This invention places the fan at one end of the inductor box and heat sink, which can guide airflow through the inductor box and heat sink, carrying away the heat from the inductor box and heat sink; the inverter inductor closer to the fan has better heat dissipation conditions and can adapt to the working conditions where the inverter inductor generates more heat; when the working conditions change and the heat generation of the boost inductor is higher, it is easy to cause the temperature of the boost inductor to become too high. Because heat pipes are inserted into the core of the boost inductor and inverter inductor, the temperature difference between the boost inductor and inverter inductor is balanced internally, thus greatly reducing the excessive temperature of the boost inductor and improving the adaptability of the heat dissipation structure to different working conditions.

[0022] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These embodiments should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0023] like Figures 1 to 4 As shown, this utility model provides an inverter with heat dissipation function, comprising:

[0024] The inverter body 1, inductor box 11, heat sink 12 and fan 13 are provided. The inductor box 11 is located at the bottom of the inverter body 1. The heat sink 12 is also located at the bottom of the inverter body 1 and is located on one side of the inductor box 11. The fan 13 is located at one end of the inductor box 11 and the heat sink 12.

[0025] Preferably, the heat sink 12 is located on one side of the inductor box 11. The heat sink 12 can conduct heat away from the heat source and release it more quickly, so as to avoid damage to the inductor box 11 due to overheating. In this invention, the fan 13 is located at one end of the inductor box 11 and the heat sink 12, which can guide the air to flow through the inductor box 11 and the heat sink 12 and carry away the heat of the inductor box 11 and the heat sink 12.

[0026] An inductor is provided inside the inductor box 11.

[0027] The inductor includes a boost inductor 21 and an inverter inductor 22. The inverter inductor 22 is located at one end of the inductor box 11 near the fan, and the boost inductor 21 is located at the other end of the inductor box 11.

[0028] The inductor has an inner core.

[0029] The inner core is equipped with a heat pipe 24.

[0030] In existing inverters, the losses of boost inductor 21 and inverter inductor 22 differ significantly under different operating conditions, resulting in uneven heat generation and a tendency for individual inductors to overheat. This invention inserts a heat pipe 24 inside the core, which can balance the temperature difference between boost inductor 21 and inverter inductor 22 and avoid the problem of local overheating of the inductors.

[0031] The inverter inductor 22, which is closer to the fan 13, has better heat dissipation and can adapt to the operating conditions where the inverter inductor 22 generates more heat.

[0032] When operating conditions change and the heat generation of boost inductor 21 increases, its temperature is prone to overheating. By inserting heat pipes 24 into the cores of boost inductor 21 and inverter inductor 22, the temperature difference between them is balanced internally. This significantly reduces the excessive temperature of boost inductor 21 and improves the adaptability of the heat dissipation structure to different operating conditions.

[0033] The space between the heat pipe 24 and the inner core is filled with insulating thermally conductive adhesive, and the gap between the inductor and the inductor box 11 is also filled with insulating thermally conductive adhesive.

[0034] The insulating thermally conductive adhesive has excellent thermal conductivity, which can effectively fill the tiny gaps between the heat pipe 24 and the inner core, and between the inductor and the inductor box 11, reducing thermal resistance and thus improving the efficiency of heat conduction from the heat source (such as the inner core of the inductor) to the heat dissipation device (such as the heat pipe 24 or the inductor box 11). This helps to dissipate heat more quickly and evenly, preventing localized overheating.

[0035] In addition, filling with insulating thermally conductive adhesive can strengthen the connection between the heat pipe 24 and the inner core, and between the inductor and the inductor box 11, reducing displacement or loosening caused by vibration or thermal expansion, thereby improving the mechanical stability and reliability of the entire system.

[0036] The inductor box 11 is provided with heat dissipation teeth 23 on its exterior.

[0037] The heat dissipation fins 23 increase the total surface area of ​​the inductor box 11, allowing more heat to be conducted from the inductor to the surrounding environment; the larger surface area means more efficient heat exchange, which helps to dissipate heat faster.

[0038] By increasing the heat dissipation area and improving airflow, the heat dissipation fins 23 help achieve a more uniform temperature distribution, reducing the risk of localized overheating and protecting the inductor and other critical components from high-temperature damage.

[0039] The inductor box 11 is filled with insulating thermally conductive adhesive. When the inverter is working, the heat generated by the boost inductor 21 and the inverter inductor 22 is transferred to the heat sink 23 through the thermally conductive adhesive, and then the heat on the heat sink 23 is removed by the fan 13. Because the inverter inductor 22 is closer to the fan 13, the inverter inductor has better heat dissipation conditions and can adapt to the operating conditions where the inverter inductor 22 generates more heat. When the operating conditions change and the heat generated by the boost inductor 21 is higher, it is easy to cause the local temperature of the boost inductor 21 to become too high. Therefore, this utility model inserts heat pipes 24 into the core of the boost inductor 21 and the inverter inductor 22, so that the temperature difference between the boost inductor 21 and the inverter inductor 22 is balanced internally, which can greatly reduce the temperature of the boost inductor 21 and improve the adaptability of the heat dissipation structure to different operating conditions.

[0040] The heat dissipation teeth 23 are one of the following: fin-shaped, needle-shaped, wavy, and plate-shaped.

[0041] Preferably, the shape of the heat dissipation teeth 23 can be fin-shaped, needle-shaped, wavy, or plate-shaped. By increasing the heat dissipation area, the heat exchange efficiency can be improved, allowing heat to be conducted from the inductor box 11 to the air more quickly.

[0042] The design of the heat dissipation fins 23 takes into account how to optimize the airflow path. Good airflow can more effectively remove heat and reduce the operating temperature of the inductor. The fin-shaped, needle-shaped, wave-shaped, and plate-shaped heat dissipation fins 23 can help guide airflow and reduce air resistance. With the help of the fan 13, the heat of the inductor box 11 can be quickly conducted into the air, improving the heat dissipation effect of the inductor box 11.

[0043] This invention incorporates a heat pipe 24 into the inductor core to achieve temperature equalization between the boost inductor 21 and the inverter inductor 22, thereby reducing the temperature difference between them and improving the adaptability of the unit's heat dissipation structure to various operating conditions, thus enhancing the inductor's heat dissipation capacity.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
