Device for generating an airflow for cooling a heat dissipating electronic element such as an LED

摘要

The device generates the upstream generation to be generated with the air stream in exit portion (20) downstream that air-flow is used to cool down the air-flow that radiating electronic element such as LED includes the inlet part (18) extended between channel (12,56), wherein the channel (12,56) include at least two substantially opposite side surfaces (14). Moreover, the equipment is mounted on channel (12,56) with the first flexible air exchange blade (10,58) and has upstream setting ventilation blade (10, (100 traffic generatings and second end (the 101, (generation of 102 downstream setting air stream in the extension channel (12,56) longitudinally extended and first longitudinal direction end (24,62) that integrally essentially coincide. The first end (24,62) of first air vent blade (10,58) is fixedly disposed, and its second end (28,70) back and forth arranges. In addition, the device includes the air exchange blade (10,58) of the reciprocal the second end (28,70) of driving element (32,34,36,66,68) in two basic lateral access (320, (321.
