(3), hollow cylinder body and function lathe is carried out cylindrical processing, and on the hollow cylinder cylindrical, bore with fan-shaped radiating fin root place and install with the corresponding installation screw of through hole according to the design size requirement;
(4) binding face with the cylindrical of the root end face of fan-shaped radiating fin and hollow cylinder fills up with heat-conducting silicone grease;
(5) with bolt fan-shaped radiating fin is fixed on the cylindrical of hollow cylinder.
When radiating fin was plane bulk radiating fin, the manufacturing step of the motor housing of the present invention's band radiating fin was:
(1) design size, the material according to the block radiating fin in plane requires and weight, prepares corresponding aluminium ingot, and aluminium ingot is heated, and places extrusion modling on the particular manufacturing craft;
(2) the block radiating fin in extrusion modling plane is carried out surface treatment, and bore the installation through hole at the root place;
(3) prepare corresponding hollow cylinder, design quantity and width according to the block radiating fin in plane, the peripheral milling of hollow cylinder is whittled into the plane of respective numbers, make it to become hollow just polygon prism, and on each plane, bore with the block radiating fin root in plane place and install with the corresponding installation screw of through hole;
(4) binding face with the plane of the root end face of the block radiating fin in plane and hollow just polygon prism fills up with heat-conducting silicone grease;
(5) with bolt the block radiating fin in plane is fixed on the plane of hollow just polygon prism.
Technique effect of the present invention is: because radiating fin is to separate making with hollow cylinder, therefore, manufacture craft is simple; Radiating fin root end face and motor housing outer surface are fitted tightr; In addition, after hollow cylinder and radiating fin are fitted, be fastenedly connected bolt before, fill up heat-conducting silicone grease at the two binding face, prevent to have air between the binding face, help improving heat dispersion.
