[0004] However, the Chinese patent with application number 202023274525.4 did not distinguish key heat-generating areas, thus limiting its heat dissipation performance.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0020] like Figures 1 to 6 As shown, the electrical control box of this utility model includes: a box body 1, a mounting bracket disposed inside the box body 1, a first cooling fan 2 mounted on the upper end of the box body 1, a housing 3 fixedly mounted on the mounting bracket, and a second cooling fan 4 mounted on the upper end of the housing 3.

[0021] The lower side wall of the box 1 has several heat dissipation holes 5; electronic components are installed in the mounting bracket and the housing 3. These electronic components need to be cooled during operation to ensure that they can work normally and efficiently, and at the same time ensure their service life; the first cooling fan 2, the second cooling fan 4 and the heat dissipation holes 5 are used to dissipate heat from the electronic components in the box 1 and the housing 3.

[0022] It should be noted that the electronic components inside the housing 3 are usually the main control part of the electronic control box, which consumes a lot of energy and generates a lot of heat. Since the space inside the housing 3 is small, in order to quickly dissipate the heat inside, the first cooling fan 2 is placed above the second cooling fan 4. Through the simultaneous action of the first cooling fan 2 and the second cooling fan 4, the heat inside the housing 3 can be quickly dissipated.

[0023] The first cooling fan 2 and the second cooling fan 4 are each provided in two sets, which can dissipate heat more efficiently. However, the power consumption of the control box varies when executing different programs, which will result in differences in the amount of heat generated. If both sets of the first cooling fan 2 and the second cooling fan 4 are operated simultaneously for a long time, unnecessary power consumption will occur. Therefore, in actual use, the operation of the first cooling fan 2 and the second cooling fan 4 needs to be reasonably allocated according to the actual usage situation.

[0024] Specifically, a control system can be set up inside the box 1. When the power consumption of the control box is normal and the heat generated is at a normal level, only one first cooling fan 2 and one second cooling fan 4 need to be turned on. When the power consumption of the control box increases and the heat generated reaches the set first threshold, two second cooling fans 4 and one cooling fan are turned on to work simultaneously. When the heat reaches the set second threshold, two first cooling fans 2 and two second cooling fans 4 are turned on to work simultaneously to quickly dissipate the heat inside the box 1 and the shell 3.

[0025] Furthermore, it should be noted that, in order to better dissipate heat from the electronic components inside the housing 3, heat dissipation fins 6 are also installed on one side of the interior of the housing 3. These fins can quickly cool the electronic components inside the housing 3 through heat exchange. Part of the second cooling fan 4 is located above the heat dissipation fins 6, and another part is located above the electronic components. Ventilation holes 15 and heat dissipation holes 5 are provided at the bottom of the housing 3. This allows the second cooling fan 4 to quickly expel heat from the heat dissipation fins 6 during operation, ensuring their efficient operation. The ventilation holes 15 also accelerate airflow within the housing 3 during the operation of the second cooling fan 4, further improving the heat dissipation effect.

[0026] In one embodiment, the mounting frame includes a base plate 7 and a slotted frame 8 fixedly mounted on both sides of the base plate 7. The slotted frame 8 has a plurality of equally spaced mounting holes 9 on both sides.

[0027] The housing 3 is mounted on one side of the slotted frame 8 via a fixing plate 10. A busbar trough 11, fixedly connected to the slotted frame 8, is located below the housing 3. Wire holes 12 are evenly distributed on the sidewalls of the busbar trough 11, serving to manage wires. Several sets of air switches are mounted on the other side of the slotted frame 8 via the fixing plate 10; relays, circuit breakers, etc., can also be installed there. By providing slotted frames 8 with openings on both sides, the space utilization of the housing 1 can be increased.

[0028] However, the dual-side installation of the housing 3 and electronic components inevitably leads to inconvenience in maintenance. The traditional single-door structure of the electrical control box cannot meet the usage requirements. Therefore, in this embodiment, the box 1 is set as a double-door structure, that is, the first door panel 13 and the second door panel 14 are installed on the front and rear sides of the box 1 respectively, so as to facilitate the maintenance of electronic components and housing 3 on different sides.

[0029] Working principle: By placing the first cooling fan 2 above the second cooling fan 4, the heat generated in the heat-generating area, namely the housing 3, can be quickly dissipated through the simultaneous action of the first cooling fan 2 and the second cooling fan 4, resulting in better heat dissipation.

[0030] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
