高导热尼龙散热器在汽车后雾灯上的应用

Application of High Thermal Conductive Nylon Heat Sink in Automobile Rear Fog Lamp

选用新型高导热尼龙材料,通过散热器翅片设计、注塑加工成型,制成高导热尼龙散热器,经过后雾灯装灯后的一系列性能验证,结果表明:与传统铝制散热器相比,新型高导热尼龙散热器在质量上降低了30%,同时满足LED后雾灯的散热及力学要求,还降低了生产成本,实现了在雾灯散热器上的“以塑代铝”。

A new type of high thermal conductive nylon material was selected to make a high thermal conductive nylon heat sink by using the heat sink fin design and injection molding.A series of performance verification after installing the rear fog lamp,the results show that compared with the traditional aluminum heat sink,the new high thermal conductive nylon heat sink reduces the quality by 30%,meets the heat dissipation and mechanical requirements of LED rear fog lamp,reduces the production cost,and realizes the"replacing aluminum with plastic"in the fog lamp heat sink.
