[0027] Please refer to Figure 1 to Figure 2An inverter back heat dissipation structure shown in an embodiment of the present application includes a cover 2, a heat dissipation component 3, a radiator 4, an inductor box 5 and a heat dissipation baffle 6. The radiator 4 is connected to the heating device in the inverter body 1 to dissipate heat from the heating device.
[0028] The radiator 4 is a plurality of heat sinks arranged at intervals, and the arrangement direction of the heat sinks is consistent with the blowing direction of the heat dissipation component 3, so as to ensure that the air blown out of the heat dissipation component 3 flows from the intervals between the heat sinks to the air outlet, thereby taking away the heat dissipated by the heat sink, accelerating the heat exchange between the heat sink and the air, and improving the heat dissipation effect of the heat sink. The number of heat sinks can be set according to demand and is not specifically limited here.
[0029] The cover 2 is disposed on the back of the inverter body 1 , and an air outlet is disposed on the cover 2 . The heat dissipation assembly 3 is disposed between the inverter and the cover 2 , and blows air toward the air outlet to form a heat dissipation duct. The radiator 4 is disposed in the heat dissipation duct.
[0030] Several inductor boxes 5 are arranged in the heat dissipation duct at intervals along the blowing direction of the heat dissipation assembly 3. In this embodiment, three inductor boxes 5 are provided, and the distance between the first inductor box 5 and the third inductor box 5 arranged along the blowing direction is roughly equivalent to the length of the heat sink, so as to reduce the installation space requirement in the vertical blowing direction, save installation space, and improve the rationality of the heat dissipation structure layout on the back of the inverter. Of course, the number of inductor boxes 5 can be set according to demand and is not specifically limited here.
[0031] The heat dissipation baffle 6 is arranged between the radiator 4 and the plurality of inductor boxes 5, and divides the heat dissipation air duct into two heat dissipation branches. The heat dissipation baffle 6 includes a plurality of air guide sections 62, which are arranged corresponding to the intervals between two adjacent inductor boxes 5 to guide the wind generated by some heat dissipation components 3 to the inductor boxes 5. Specifically, since the inductor box 5 closest to the heat dissipation component 3 can be directly flowed to by the wind blown out by the heat dissipation component 3, while the remaining inductor boxes 5 cannot, the number of air guide sections 62 is one less than the number of inductor boxes 5, and the wind on the side of the inductor box 5 close to the heat dissipation baffle 6 is guided by the air guide section 62 to flow to the inductor box 5, thereby ensuring that each inductor box 5 can be cooled by air.
[0032] In addition, when the number of the inductor boxes 5 is large, multiple rows can be arranged at intervals along the blowing direction, and heat dissipation partitions 6 are provided between the multiple rows of inductor boxes 5 to ensure that the wind blown out by the heat dissipation component 3 flows to each inductor box 5 .
[0033] The wind guide section 62 is an inclined wind guide plate, with one end of the wind guide plate close to the heat dissipation component 3 being arranged away from the inductor box 5, and one end of the wind guide plate close to the air outlet being arranged close to the inductor box 5. This arrangement ensures that the wind generated by the heat dissipation component 3 flows toward the inductor box 5 along the inclined direction of the wind guide plate under the action of the wind guide plate.
[0034] The heat dissipation baffle 6 also includes a plurality of spacer plates 61, and the spacer plates 61 and the air guide plates are connected end to end in sequence. In this embodiment, the spacer plates 61 and the air guide plates are integrally formed, and the spacer plates 61 are arranged along the blowing direction and gradually approach the inductor box 5 from the heat dissipation component 3 to the air outlet, and the air guide plates are used to connect two adjacent spacer plates 61.
[0035] Of course, in other embodiments, the air guide plate can be extended from the partition plate 61 toward the inductor box 5, and the length of the partition plate 61 gradually increases from the heat dissipation component 3 toward the air outlet. Alternatively, the partition plate 61 and the air guide plate are separately provided, and the air guide plate is staggered and distributed in the heat dissipation branch channel where the inductor box 5 is located along the blowing direction.
[0036] The cover 2 is a square structure, and forms a rectangular space with the back of the inverter body 1. The rectangular space is conducive to the arrangement of the heat dissipation component 3 and the air outlet to form a smoother heat dissipation air duct and reduce wind resistance. Of course, in other embodiments, the cover 2 can also be other shapes, which are not specifically limited here.
[0037] The heat dissipation component 3 is arranged at the bottom of the rectangular space. Blowing air from bottom to top, combined with the upward movement of hot air, can reduce the heat dissipation pressure of the heat dissipation component 3. Of course, in other embodiments, the heat dissipation component 3 can also be arranged at other positions as long as it can meet the corresponding functions, and no specific limitation is made here.
[0038] The air outlet includes a first air outlet 21 arranged at the top of the rectangular space and a second air outlet 22 arranged at the side of the rectangular space, and the second air outlet 22 is arranged corresponding to the inductor box 5. Among them, the first air outlet 21 is used for most of the wind generated by the heat dissipation component 3 to flow out. Since the wind generated by part of the heat dissipation component 3 flows obliquely under the action of the wind guide plate, the second air outlet 22 is opened on the side of the cover body 2 for its oblique outflow. In order to reduce the air outlet pressure at the top of the cover body 2, a third air outlet 23 is opened on the side of the top of the cover body 2 facing the back of the inverter to cooperate with the first air outlet 21 for exhaust.
[0039] The heat dissipation assembly 3 includes a fixing bracket 31 mounted on the back of the inverter body 1 and a plurality of airflow generating members 32 mounted on the fixing bracket 31. The fixing bracket 31 extends horizontally along the bottom of the cover body 2, and a plurality of airflow generating members 32 are arranged on the fixing bracket 31 at intervals. The plurality of airflow generating members 32 work together to reduce the power requirements of the airflow generating members 32. The airflow generating member 32 is specifically a fan.
[0040] The present application sets a cover body, a heat dissipation component, a radiator and a heat dissipation baffle on the back of the inverter body, uses the heat dissipation component to blow air toward the air outlet of the cover body to form a heat dissipation air duct, and uses the radiator and the heat dissipation component to cooperate to dissipate heat from the heating components of the inverter. The heat dissipation method is diversified and the heat dissipation effect is better. Secondly, the heat dissipation baffle is used to separate the radiator and the inductor box in two independent heat dissipation branches. The heat dissipation baffle can effectively isolate the influence of the heat emitted by the radiator on the inductor. At the same time, the wind generated by the heat dissipation component flows to each inductor box under the action of the air guide section of the heat dissipation baffle to ensure that each inductor box is cooled by air, thereby improving the heat dissipation effect, avoiding heat damage to various components of the inverter, and further increasing the service life of the inverter.
[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
