Tokyo, Jan 26, 2012 (JCN) - DENSO Corporation developed a new radiator that is 40 percent smaller and lighter, compared to DENSO's previous radiators. Also, the radiator's tank is made with a plant-derived resin making it more environmentally friendly than conventional radiators.
With higher heat radiation efficiency, the new radiator is only 16 mm wide, but equal in performance to the conventional 27 mm wide radiator, resulting in a substantial size and weight reduction. A radiator's performance depends on its two major components - fins and tubes.
DENSO increased the amount of louvers - that are located on the surface of the fin - to 30 percent per unit area. This design change allowed the radiator to have 10 percent more efficient heat radiation than DENSO's conventional radiators.
DENSO, along with a materials manufacturer, has jointly developed thinner and higher-strength materials that are used to make the fins and tubes. The fin, using DENSO's manufacturing expertise, is the world's thinnest of its kind. The radiator offers the same strength as DENSO's previous radiators while using thinner materials. All these advantages enabled the radiator to be 40 percent smaller and lighter than the previous models.
In addition, the radiator's tank is made of plant-derived resin, which DENSO has been mass-producing since 2009, making the radiator greener and environmentally cleaner than traditional radiators.
The new radiator is installed in the Lexus GS. DENSO will also commercialize a 27 mm wide type, which is thinner than the conventional model of 36 mm type, and 11.5 mm wide type which are thinner than the conventional model of 16 mm, to offer a wider range of the new radiator series for a greater range of vehicle models.
