Description

Technical Field

[0001] The utility model relates to a heat dissipation system, in particular to a heat dissipation system for a variable-frequency generator controller. Background Art

[0002] A general variable-frequency generator refers to a mechanical device that converts mechanical energy into electrical energy. Since the controller of the variable-frequency generator includes a plurality of electrical components, during the power generation process of the variable-frequency generator, a large amount of heat will be generated by the controller, resulting in an increase in the temperature of the electrical components. Once the temperature of the electrical components is too high, it will affect the operation of the electrical components or even cause damage. Therefore, it is necessary to dissipate heat from the controller.

[0003] Chinese Patent Document CN220168028U discloses a generator, which includes an engine and a controller. The engine includes a wind guide cover and an impeller installed in the wind guide cover. Among them: there is also an installation frame, and the controller is fixed on the installation frame; there is a suction cavity between the wind guide cover and the impeller, and the wind guide cover is provided with a suction port communicated with the suction cavity; the controller is provided with a wind guide cover, and part or all of the wind guide cover wraps the controller to form an air intake channel, and the suction port is communicated with the air intake channel. The utility model can forcibly guide the airflow passing through the controller, and then cooperate with the suction method to make the airflow forcibly blow through the controller, taking away most of the heat of the controller, so as to improve the heat dissipation effect of the controller.

[0004] Although the heat dissipation effect can be improved by forcibly guiding the airflow in the prior art, it is impossible to effectively dissipate heat from the high-temperature area during the heat dissipation process, resulting in insufficient heat dissipation in some parts, while there is also an overheat dissipation situation in some areas. Summary of the Utility Model

[0005] In order to solve the technical problem of insufficient pertinence in the heat dissipation of the variable-frequency generator in the prior art, the utility model provides a heat dissipation system for a variable-frequency generator controller, which includes a controller and a wind guide housing. The controller is located inside the wind guide housing. The wind guide housing is provided with an air intake port and an air outlet. The controller includes heat-generating electrical components. One side of the heat-generating electrical components is provided with a heat dissipation plate, and the heat dissipation plate is provided with a plurality of heat dissipation ribs. The heat dissipation ribs extend from the air intake port direction towards the air outlet direction to form a plurality of heat dissipation channels. Among them: the heat dissipation channels are provided with a first heat dissipation area with a high flow rate and a second heat dissipation area with a low flow rate.

[0006] Compared with the prior art, in this solution, the heat dissipation channels are divided into a first heat dissipation area with a high flow rate and a second heat dissipation area with a low flow rate. Therefore, the heat dissipation efficiency of the first heat dissipation area is higher, which can ensure the heat dissipation of the high-temperature area, while the heat dissipation efficiency of the second heat dissipation area is relatively low, which can also avoid overheat dissipation of the low-temperature area. Thus, it can avoid the situation of insufficient heat dissipation or overheat dissipation of some components, has a simple structure, and can also reduce the production cost of the heat dissipation system.

[0007] Preferably, a blocking portion is provided in the heat dissipation channel of the second heat dissipation area. In this solution, the setting of the blocking portion can achieve low-flow heat dissipation, and the structure is simple.

[0008] Preferably, the blocking portion is located on the air outlet side of the heat dissipation channel.

[0009] Preferably, the number of heat dissipation ribs in the first heat dissipation area is set to be greater than that in the second heat dissipation area. In this solution, by adjusting the number of heat dissipation ribs, the heat dissipation effect can be enhanced or weakened, and the structure is simple.

[0010] Preferably, the heating electrical element includes a main heating electrical element and a secondary heating electrical element. The main heating electrical element is located in the first heat dissipation area, and the secondary heating electrical element is located in the second heat dissipation area. In this solution, the main heating electrical element is arranged in the first heat dissipation area to dissipate heat with high flow rate, and the secondary heating element is arranged in the second heat dissipation area to dissipate heat with low flow rate, which can avoid the situation of insufficient heat dissipation of the main heating electrical element and excessive heat dissipation of the secondary heating electrical element, and the structure is simple.

[0011] Preferably, the heating electrical element includes a first temperature-resistant interval electrical element and a second heat-resistant interval electrical element. In this solution, temperature-resistant management is carried out on the heating electrical element to avoid overheating damage or excessive heat dissipation.

[0012] Preferably, the first temperature-resistant interval electrical element is located on the air inlet side of the second temperature-resistant interval electrical element. With the setting in this solution, the temperature at the air inlet is relatively low, which can reduce the thermal influence of other heating electrical elements.

[0013] Preferably, it further includes mounting brackets located on both the upper and lower sides of the controller. The mounting brackets are provided with longitudinally adjustable mounting strip holes or mounting grooves. The mounting strip holes or mounting grooves provided in this solution can adjust the position of the controller to a certain extent, so that the supporting force of the controller is on the lower side, ensuring a stable support for the controller.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the heat dissipation channel is divided into a first heat dissipation area with high flow rate and a second heat dissipation area with low flow rate. Therefore, the heat dissipation efficiency of the first heat dissipation area is higher, which can ensure the heat dissipation of the high-temperature area, while the heat dissipation efficiency of the second heat dissipation area is relatively low, and it can also avoid the situation of excessive heat dissipation of the low-temperature area. Thus, it can avoid the situation of insufficient heat dissipation or excessive heat dissipation of some components, the structure is simple, and the production cost of the heat dissipation system can also be reduced.

[0027] The embodiment is basically as shown in the attached... Figures 1 - 5 A variable - frequency generator controller heat - dissipation system includes a controller, an air - guiding housing 1, and mounting brackets located on the upper and lower sides of the controller, including an upper mounting bracket 10 and a lower mounting bracket 11. The controller is located inside the air - guiding housing 1. The air - guiding housing 1 is provided with an air inlet 6 and an air outlet 9. The controller includes a heating electrical component 7. One side of the heating electrical component 7 is provided with a heat - dissipating plate 8. A plurality of heat - dissipating ribs 2 are provided on the heat - dissipating plate 8. The heat - dissipating ribs 2 extend along the air - inlet direction towards the air - outlet direction to form a plurality of heat - dissipation channels. The mounting bracket is provided with longitudinally adjustable mounting slot holes or mounting slots 12. The lower mounting bracket 11 is as shown in... Figure 5 The lower mounting bracket 11 is provided with a mounting slot 12.

[0028] The heat - dissipation channels are provided with a first heat - dissipation area 4 with a high flow rate and a second heat - dissipation area 5 with a low flow rate. The heating electrical component 7 includes a main heating electrical component 7 and a secondary heating electrical component 7. The main heating electrical component 7 is located in the first heat - dissipation area 4, and the secondary heating electrical component 7 is located in the second heat - dissipation area 5.

[0029] A blocking portion 3 is provided in the heat dissipation channel of the second heat dissipation area 5, and the number of heat dissipation ribs 2 in the first heat dissipation area 4 is set to be greater than the number of heat dissipation ribs 2 in the second heat dissipation area 5. In this embodiment, the blocking portion 3 is located on the air outlet side of the heat dissipation channel. In other embodiments, the blocking portion can also be provided at other positions.

[0030] The heating electrical element 7 includes a first temperature-resistant interval electrical element and a second heat-resistant interval electrical element, and the first temperature-resistant interval electrical element is located on the air inlet side of the second heat-resistant interval electrical element.

[0031] Note: In the present utility model, the air inlet and air outlet are based on the flow direction of the air flow.

[0032] The specific implementation process is as follows: During operation, the external cold air enters the heat dissipation channel from the air inlet 6, flows along the heat dissipation channel, and then blows out from the air outlet 9. During the flow, it drives the heat of the heating electrical element 7 in the controller, achieving the effect of heat dissipation and temperature reduction. When the air flows in the second heat dissipation area 5, since the blocking portion 3 is provided in the heat dissipation channel of the second heat dissipation area 5, the flow of the air in the second heat dissipation area 5 is blocked by the blocking portion 3, so the air flow rate decreases, thereby avoiding the situation of excessive heat dissipation of the secondary heating electrical element 7 at the second heat dissipation area 5.
