The purpose of the utility model is accomplished through following technical scheme, and it comprises accumulation of heat aluminium post, aluminium installing plate and fin, and described accumulation of heat aluminium post cylindrical is provided with a plurality of trapezoidal grooves, is aluminium post groove; Fin utilizes the elastic properties of materials distortion tightly to insert aluminium post groove, and aluminium installing plate and accumulation of heat aluminium post are fastenedly connected, and are combined into a LED bulkhead lamp capable radiator.

As preferably, described accumulation of heat aluminium post center is processed to part for stepped hollow, and the cross section is parabola shaped hollow cavity, is pressed with a cover plate on the hollow cavity of this accumulation of heat aluminium post; The aluminium post groove quantity of accumulation of heat aluminium post cylindrical is 16,20,24 and 28 four kinds.

As preferably, the cross section of described fin is the section shape of three-stage rocket, and inside is cavity; And has the structure that prevents that fin from coming off with the convexity on the fin both sides of aluminium post groove connection.

As preferably; Described aluminium installing plate and accumulation of heat aluminium post are fastenedly connected; Aluminium installing plate center hole and accumulation of heat aluminium pylon rank are that interference press-fits, and the junction of the edges of two sheets of paper of both faying faces bores tapping and be screwed into holding screw, in the cylindrical hole of holding screw head behind the riveted joint aluminium rivet processing smooth.

The beneficial effect of the utility model is: utilize the elastic properties of materials of fin cavity and the formation of accumulation of heat aluminium post trapezoidal groove to combine closely, in order to the conduction heat, its cavity can form the structure that the similar chimney that puts a chimney on the stove and make the fire draw is beneficial to hot-air and cold air exchange again; For the ease of accessories such as light source, lens and lampshade are installed; Heating surface at accumulation of heat aluminium post press-fits circular aluminium installation base plate of combination; Its combining form prevents axial displacement and prevents with the holding screw that secretly buries to rotate; In order not influence light source installation and attractive in appearance, precision-machined surface behind the holding screw oral area riveted joint aluminium rivet; The utility model is compared with the aluminium section bar heronsbill radiator of routine, has advantages such as good heat-transfer, in light weight, low price, good looking appearance.
