The heater core reheats a portion of the air cooled by the evaporator by exchanging heat with engine-cooling water. The reheated air is mixed with the remaining evaporator-cooled air and the mixed air is blown into the vehicle cabin.
DENSO Technology – Leading the World
- In 2002, DENSO introduced a smaller, lighter heater core – 27 mm in width – achieving the same performance as the company’s conventional 46 mm heater core. The new heater core has the world’s thinnest tube plate of 0.2 mm.
Benefits and Features
- Small size (thin width)
- Thinner tube (1.3 mm) and smaller fin height (3.9 mm) improves heat exchange efficiency.
- Light weight
- The tube’s zinc (Zn) diffusion layer improves corrosion resistance, resulting in very thin tube plate thickness (0.2mm).
