For achieving the above object, a kind of LED vertical convection radiator in this novel technical scheme, include: both ends open is linked to be the cylindrical drum shell of cavity and the radiating piece in the cylindrical drum shell cavity, described radiating piece is section bar, the cross section of radiating piece is by the heat-conductive connection part that is positioned at cylindrical drum shell center and evenly outwards disperse the radiating ribs more than 3 or 3 that is molded over the heat-conductive connection part periphery and consist of, and the outer end of radiating ribs links to each other with cylindrical drum shell inwall so that the cavity of cylindrical drum shell is split into several vertical convection independent of each other chambeies.
Described cylindrical drum shell and radiating piece are one-body molded to be same parts.
The both sides of described heat-conductive connection part are distributed with several radiating fins.
The both sides of described radiating ribs are distributed with several radiating fins.
Radiating fin and radiating ribs on described several radiating ribs are same angle.
The height of described cylindrical drum shell is consistent with the height of described radiating piece, and the two ends of described radiating piece are concordant with the both ends open of described cylindrical drum shell respectively.
Form the connecting screw hole that supplies fastened by screw, is used for connecting the LED light engine on the described heat-conductive connection part.
Form the connecting screw hole that supplies fastened by screw, is used for connecting lens subassembly on described a part of radiating ribs.
Be distributed with several vertical radiating grooves one on the described cylindrical drum shell inwall.
Be distributed with several vertical radiating grooves two on described radiating ribs and the radiating fin.
After adopting said structure, this novel pin is to the radiator of cylindrical drum shell with sealing, the heat-conductive connection part that utilization is positioned at cylindrical drum shell center is connected with the LED light engine carries out and heat loss through conduction, and the outer end of adopting radiating ribs links to each other with cylindrical drum shell inwall and can utilize the air vertical convection to the other end opening in vertical convection chamber from an end opening in several vertical convection chambeies so that the cavity of cylindrical drum shell is split into the heat that the structure in several vertical convection independent of each other chambeies produces the LED light engine, realizes the air vertical convection in individual independent vertical convection chamber is dispelled the heat.In addition, the radiating fin on this is novel and the architectural feature of vertical radiating groove are conducive to increasing heat radiation area, and heat can be diffused in the air quickly.Because this novel radiator structure all is hidden in the cylindrical drum shell, makes its external styling attractive in appearance.As from the foregoing, this new structure is novel, aesthetic in appearance, has adopted the cross-ventilation heat dissipation technology greatly to increase the harmony and the radiating efficiency that dispel the heat, the tropical island effect of avoiding hot-spot to produce.
