AI Technical Summary
Existing cooling apparatuses for vehicle batteries incur high product costs due to the need for individual detection devices for each heat exchange unit to adjust refrigerant flow volumes, which is necessary to prevent superheat and ensure efficient cooling.
A cooling apparatus design with a refrigerant distribution and convergence system that adjusts refrigerant flow volumes across multiple heat exchange units by using a single downstream detection device, minimizing the need for individual detectors by varying flow path cross-sectional areas and utilizing an ECU to control the expansion valve based on detected refrigerant conditions.
This design effectively adjusts refrigerant flow to prevent superheat while reducing product costs by minimizing the number of detection devices, ensuring efficient cooling of vehicle batteries without compromising compressor performance.
