Radiator, cold forging process of radiator and lamp

Abstract

The invention discloses a radiator. The radiator comprises cooling fins evenly distributed on the surface of the radiator, installation cylinders and wire passing cylinders, wherein the installation cylinders and the wire passing cylinders are distributed on the cooling fins at intervals, the installation cylinders are used for being assembled with screws or bolts in a screwed manner, and the wirepassing cylinders are used for wires to pass through. The invention further discloses a cold forging process of the radiator and a lamp with the radiator. The radiator is good in heat dissipation effect, and relatively good heat dissipation performance can be provided for the lamp. The cold forging technology is adopted to the radiator, manufacturing of a more complex radiator structure can be achieved, and under the situation of the same heat dissipating effect, the size and the weight of the radiator are reduced. The cold forging machining technology is high in precision and is more beneficial to improvement of the assembling efficiency. By means of the cold forging machining technology, the speed is high, and the production period is shortened. The lamp is provided with a heat convection structure and the radiator for double heat dissipation and is good in heat dissipation effect, and the service life can be effectively improved.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a radiator, its cold forging process and a lamp. Background technique [0002] A lamp is an object that uses a light source to energize and emit light. In special lighting occasions, the lamp requires high-light illumination, so its calorific value is relatively large, so it is necessary to install a radiator in the lamp to assist the lamp in cooling. [0003] Most of the existing radiators are manufactured by die-casting, and most of the processes are as follows: aluminum block is melted into aluminum water → die-casting → deburring → shot blasting → plastic spraying. Although this method can manufacture heat sinks with complex structures, its heat dissipation effect is not good, and its weight is too large, its thickness and draft angle are relatively large, so it cannot be adapted to lamps with very strict heat dissipation requirements. [0004] Therefore, the applicant proposes a heat s...
