散热器是车辆冷却系统的核心附件,它的作用是吸收发动机所产生的热量并将其散发到空气中,以保护发动机避免因过热造的破坏。在车辆排放法规日渐严格,能源储存量逐步降低的大背景下,“节能减排”将成为汽车工业发展的重点。因此高效、节能、紧凑是摆在散热器行业面前的重要课题。本文阐述了汽车散热器的发展现状,为散热器高效化和轻量化研究奠定了理论基础。 Radiator is the core of the vehicle cooling system accessories, its role is to absorb the heat generated by the engine and its distribution to the air to protect the engine to avoid damage caused by overheating. In the context of increasingly stringent vehicle emissions regulations, energy reserves gradually reduce the background, “energy saving ” will become the focus of the development of the automotive industry. Therefore, efficient, energy saving, compact is placed in front of the radiator industry an important issue. This article expounds the development status of the automobile radiator and lays a theoretical foundation for the research on the radiator efficient and lightweight.
