<p>A heat radiation fan which could be installed on corresponding position of the heat-radiating fins of a CPU or a heat-radiating hole-plate of a computer cabinet, includes: a fan body (3), a fan frame (2) and a fan impeller (1). The fan frame (2) is circular in shape. The fan body (3) is arranged along the outer circumference of the fan frame (2). The fan impeller (1) is installed in the fan frame (2). A rubber layer (4) is arranged at the outer surface of the fan body (3), and the place that touches the eat-radiating fins at upside and downside edges of the fan frame (2). The rubber layer (4) is formed by secondary injection molding. Through holes (31) are set through the upper and lower part at four end corners of the fan body (3). The rubber layers are also set at the inner surfaces of the through holes, after secondary injection molding, the upside edges of the through holes keep level with corresponding upside and downside edges of the fan frame (2). The invention can achieve flexible touch between the eat radiation fan and the heat-radiating fins or the heat-radiating hole-plate of a computer cabinet, counteract longitudinal and transverse impulsive vibration effectively and decrease noise.</p> |
