Description

Technical Field

[0001] The utility model relates to the technical field of pulse controllers, in particular to a pulse controller with good heat dissipation effect. Background Art

[0002] The pulse controller is the main control device for the pulse bag dust collector to clean the dust. Its output signal controls the electromagnetic pulse valve to clean the filter bag in a cycle to ensure the dust collector's processing capacity and dust collection efficiency. It is mainly used in kilns, cement kilns, mines and other industries.

[0003] The patent with announcement number CN213492584U proposes a pulse controller with good heat dissipation effect, including a pulse controller housing, an anti-collision structure, an air-cooled heat dissipation structure, a circuit board, a bolt column, a support pad, and a protective pad. The outer surface of the pulse controller housing is provided with an anti-collision structure, and the interior of the pulse controller housing is provided with an air-cooled heat dissipation structure. The interior of the pulse controller housing is provided with a circuit board, and bolt columns are installed at the four corners of the circuit board. The four corners of the lower end face of the pulse controller housing are provided with support pads, and the lower end face of the pulse controller housing is connected with a protective pad. The utility model can play an anti-collision protection effect through the anti-collision structure provided, so that it can ensure that the electrical components inside the device will not be damaged when the device is hit, thereby improving the service life of the device. At the same time, the protective pad provided can increase the friction between the device and the contact surface, so as to ensure the stability of the device installation.

[0004] During the use of the above case, it is difficult for the cooling fan to evenly dissipate the heat for the circuit board inside the pulse controller housing, resulting in incomplete heat dissipation, thereby reducing the heat dissipation efficiency of the device. In addition, the pulse controller housing is not provided with a dustproof mechanism, which may easily cause dust in the air to fall onto the surface of the circuit board due to long-term use, affecting the use of the circuit board, thereby bringing inconvenience to the use of the pulse controller. For this reason, the present application proposes a pulse controller with good heat dissipation effect. Utility Model Content
