Denso designs radiators with increased amount of louvers that are located on the surface of the fin—to 30% per unit area. This increases capability of heat radiation of the radiators by 10% compared to conventional radiators. Denso has also developed thinner and higher-strength materials that are used to make the fins and tubes of the radiator. This new material allows the radiators to be cost effective and very durable. These light radiators by Denso are 40% smaller and lighter than the previous models are equally durable. The configurations of Denso radiators and the tanks, fin pitch, core dimensions and materials meet OE manufacturer's rigid standards. As the result, these radiators deliver exceptional performance even under the most demanding conditions.
