AI Technical Summary
Technical Problem
The existing vacuum booster housing has insufficient heat dissipation capacity, which leads to increased internal temperature during continuous braking, causing the booster diaphragm to age and affecting braking performance.
Method used
The system employs an arc-shaped heat dissipation slide structure driven by phase change material and shape memory alloy encased in a ring cylinder, combined with a cavity design and heat-conducting rods, to achieve active heat dissipation, expand the heat dissipation area, and enhance the air convection channel.
Benefits of technology
It effectively slows down the temperature rise, significantly improves heat dissipation efficiency, maintains stable booster performance, and avoids loss of housing sealing.
