Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrical heat dissipation devices, in particular to a heat dissipation structure used for an electrical converter. Background Art
[0002] As we all know, an electrical converter is an electrical device that changes the voltage, frequency, number of phases and other electrical quantities or characteristics of a power supply system. In addition to the main circuit, the converter also needs a trigger circuit that controls the on and off of the power switching elements and a control circuit that realizes the regulation and control of electric energy. The trigger circuit of the converter includes two parts: a pulse generator and a pulse outputter. The former generates a pulse of a certain frequency, a certain width or a certain phase according to the requirements of the control signal; the latter amplifies the level of this pulse into a driving signal suitable for the power switching elements in the converter. As an electrical device that changes the voltage, frequency, number of phases and other electrical quantities or characteristics of a power supply system, the converter has been widely used in the transportation industry, manufacturing industry, etc., such as the shipping industry and the electroplating production industry.
[0003] The current heat dissipation structure of electrical AC units usually has a fan installed on the top of the cabinet and ventilation holes set on the side walls. The rotation of the fan drives the air flow to cool the electrical AC unit. Although this method can initially achieve a cooling effect, it still has some shortcomings. Dust in the air will enter the cabinet with the rotation of the fan, causing dust accumulation over a long period of time, which is difficult to clean and causes a decrease in the heat dissipation efficiency of the electrical AC unit.
