Description

Technical Field

[0001] This utility model relates to a soft starter with good heat dissipation. Background Technology

[0002] In practical applications, the power components (such as thyristors and IGBTs) inside soft starters generate significant heat. Currently, most soft starters on the market use air cooling, typically employing fans and ventilation holes within the soft starter cabinet to quickly dissipate heat. This cooling method has the following significant drawbacks: 1. While the ventilation holes help dissipate heat, they also easily allow dust from the external environment to enter the equipment. After prolonged operation, dust accumulates in the cooling channels, clogging the ventilation holes, reducing cooling efficiency, and even causing overheating failures; 2. Traditional fans and dust filters are mostly non-removable, making it difficult for maintenance personnel to easily clean or replace them. When the fan accumulates dust or is damaged, the entire device needs to be disassembled for maintenance, greatly increasing maintenance costs and time. Therefore, improvements and optimizations are needed to address these issues. Utility Model Content
