Casement LED heat sink of the present utility model comprises heat-conducting substrate, and the heat conduction connection of described heat-conducting substrate surface is provided with radiating fin, and the heat-conducting substrate edge is extended at described radiating fin two ends, between the adjacent radiating fin slit is set.
Further, described radiating fin plane of living in and heat-conducting substrate surface forms the angle greater than 0 °;
Further, described radiating fin surface is a flat surface;
Further, described radiating fin surface is the flow-disturbing treatment surface;
Further, the thickness of described radiating fin is 0.1-0.8mm;
Further, described radiating fin and heat-conducting substrate are one-body molded;
Further, adopt welding, bonding or expanded joint between described radiating fin and the heat-conducting substrate;
Further, the material of described radiating fin and heat-conducting substrate is metallic copper or alloy aluminum;
Further, described heat-conducting substrate is a rectangular configuration, and radiating fin is provided with perpendicular to the long limit of rectangular configuration;
Further, at least one LED lamp pearl is installed on the described heat-conducting substrate, constitutes lamp unit, fixedly connected being arranged on the frame-type lamp bracket constitutes light fixture between the adjacent lamp unit.
The beneficial effects of the utility model: casement LED heat sink of the present utility model, adopt two ends to extend the radiation fin structure of heat-conducting substrate, in adjacent radiating fin extends slit between the heat-conducting substrate part, air can flow freely, airflow direction and temperature difference direction form less angle, thereby has fabulous heat dispersion, growth along with life cycle, can keep more stable heat dissipation capacity, can under condition, reduce the temperature rise of great power LED effectively, reduce the light decay of LED without other power, thereby guarantee the user mode of LED lamp and increase the service life the cost of reduction LED lamp thermal component; The utility model structurally is divided into radiating fin main radiator portion of extending heat conduction substrate and the auxiliary heat dissipation part that is connected with heat conduction substrate, the extended part of fin is directly passed owing to air-flow, form the main surface of heat radiation, bear about 90% heat transfer free convection, pollutant is because washing away of air-flow can't stay in radiating fin, thereby work as dust, tail gas, composite pollution materials such as oil smoke are during with airflow passes master radiator portion, main radiator portion is not exerted an influence, and mainly attached on the auxiliary heat dissipation part surface, thereby the utility model can be applicable to dust, tail gas, the occasion of composite pollutions such as oil smoke is as the heat radiation of LED street lamp and LED Tunnel Lamp.
