The air outlet 2 is arranged on the back of the electric control cabinet shell 1, and as other electric control cabinets or other structures are not arranged on the back of the electric control cabinet shell 1, the exhausted hot air flow cannot influence other structures. The back surface of the electric control cabinet shell 1 is usually large in external space, so that heat dissipation performance is good.
In this embodiment, the front panel of the cabinet housing 1 is provided with an air inlet 8. The air inlet 8 is used for introducing air flow with lower temperature into the electric control cabinet shell 1.
As shown in fig. 6 and 7, in other embodiments, the air outlet 2 may be provided on a side plate of the cabinet housing 1, for example, on a left side plate or on a right side plate. Of course the number of the devices to be used, the air outlet 2 may also be provided on the top panel.

Meanwhile, the air inlet 8 and the air outlet 2 are additionally provided with the filtering fence, so that external impurities can be prevented from entering the electric control cabinet shell 1, and the operation of elements in the cabinet is prevented from being influenced.
Optionally, the frequency converter 5 inside the electric control cabinet shell 1 adopts a vertical installation mode so as to be matched with the radiating pipe 3, and ensure the radiating effect. When the frequency converter 5 is installed, a space of at least 200mm is reserved above and below the frequency converter to utilize the flow of ambient air.
The frequency converter 5 includes a frequency conversion heat dissipation section 32, and the heat dissipation fan 4 is disposed in the frequency conversion heat dissipation section 32. In this embodiment, the variable frequency heat dissipation air duct of the variable frequency heat dissipation section 32 is a vertical air duct, the lower end thereof is an air inlet, the upper end thereof is an air outlet, and the heat dissipation fan 4 is disposed at the air outlet, i.e. the upper end of the variable frequency heat dissipation section 32.
The radiating pipe 3 includes a main radiating section 31. The first end of main radiating section 31 is connected on automatically controlled cabinet casing 1, and corresponds air outlet 2, and radiator fan 4 in the frequency conversion radiating section 32 on the converter 5 is located the upper end rear portion of converter 5, and when radiator fan 4 was operated, the cold air was got into converter 5 from the frequency conversion radiating wind channel air intake of the lower extreme of frequency conversion radiating section 32, takes away the inside heat of converter 5 to discharge converter 5 from the upper end.

When the frequency converter 5 operates, hot air exhausted from the cooling fan 4 is output to the outside of the electric control cabinet shell 1 through the folded pipeline, namely, heat of heating elements in the electric control cabinet shell 1 is directly exhausted to the outside, the heat is not required to be exhausted to the inside of the electric control cabinet shell 1, and then the heat is exhausted out of the cabinet through the cooling fan on the cabinet door. Therefore, the heat can be accurately discharged, the influence of hot air on other elements is reduced, meanwhile, the cabinet body cooling fan can be omitted, and the failure rate of the electric control cabinet is reduced.
The sizes of the air outlets of the upper-end cooling fans 4 of the frequency converters 5 with different specifications and models are different.

Alternatively, the number of flaps 6 is at least two, each flapper 6 is mounted on the main heat dissipation section 31 by a corresponding mounting shaft 7. The movable baffles 6 are arranged on at least two opposite side walls of the main heat dissipation section 31, and different ventilation areas are adjusted through rotation of the two movable baffles 6.
Preferably, 4 flaps are mounted on the second end of the main heat sink section, one flap 6 being mounted on each side wall of the main heat sink section 31, which is connected to the main heat sink section 31 by a mounting shaft 7 (e.g., a living hinge). The movable baffle 6 can be manually adjusted in angle and can be fixed at any angle, and the angle can be automatically adjusted. The angles of the 4 movable baffles 6 are adjusted aiming at the frequency converters with different specifications, so that the opening degree of the movable baffles 6 is matched with the frequency converter 5, and heat discharged by the frequency converter 5 can be gathered and discharged through a heat dissipation channel.

Alternatively, the mounting shaft 7 is connected with a mounting wheel 71, the mounting shaft 7 can rotate relative to the mounting wheel 71, and the plurality of limiting grooves 711 are uniformly distributed on the mounting wheel 71 along the circumferential direction of the mounting wheel 71. By arranging a plurality of limiting grooves 711 on the mounting wheel 71, different angle demands can be met, and the adaptability is better.
Alternatively, in order to more conveniently adjust the angle of the flapper 6, an elastic member is connected to the limit projection 61, and the limit projection 61 is movably provided on the flapper 6 in the axial direction of the mounting shaft 7 by the elastic member. When the angle of the movable baffle 6 needs to be adjusted, the limiting protrusion 61 can be withdrawn from the limiting groove 711, then the movable baffle 6 is rotated to a required angle, and then the limiting protrusion 61 can be automatically moved into the limiting groove 711 by utilizing the elastic restoring force of the elastic piece, so that the angle is fixed.
The electric control cabinet has the following technical effects:
the heat dissipation channel is utilized to directly transfer hot air exhausted by the frequency converter to the outside of the cabinet, and the cabinet body does not need to be provided with a heat dissipation fan. The cabinet body cooling fan is reduced, so that the cost can be reduced, and the failure rate of the electric control cabinet can be reduced; and the type selection of the cooling fan is not needed, so that the development efficiency is improved.
The 4 movable baffles of the radiating pipe can be used for matching frequency converters with different specifications, so that the requirements of generalization and standardization are met.
