Cooler Sizing Software
In water-cooled cooling systems for converters, motors, chargers, and batteries, the coolant distribution can be configured in series, parallel, or a hybrid of both. Each configuration necessitates careful analysis of temperature curves to ensure that every component receives adequate cooling capacity. This is crucial for maintaining optimal performance under varying ambient conditions and power outputs.
