Abstract

The invention provides a heat dissipation device which comprises a fixing assembly, a stator assembly and a rotor assembly; the fixing assembly comprises a shell and a fixing base connected with the shell; the stator assembly comprises a coil and a PCBA board connected with the coil, and the stator assembly is installed on the fixing base; the rotor assembly comprises a mounting base, a pluralityof fan blades connected with the mounting base, a rotating shaft connected with the mounting base, and a positioning piece, a bearing and an elastic piece which are connected in sequence; the end, away from the mounting base, of the rotating shaft is connected with the shell; the positioning piece is connected with the end, away from the mounting base, of the rotating shaft, and the positioning piece, the bearing and the elastic piece are all arranged in the fixing base. According to the heat dissipation device, the rotating shaft is sleeved with the elastic piece, the bearing and the positioning piece in sequence; the elastic piece abuts against the fixing base; the positioning piece is connected with the rotating shaft, and therefore the bearing is fixed; one end of the rotating shaft isconnected with the mounting base, and the other end abuts against the shell to ensure reliable rotating shaft connection; and the heat dissipation device is reliable and stable in structure, cost-saving and long in service life.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to a radiator. Background technique [0002] With the development of science and technology, electronic products are used more and more widely. However, the use of electronic products will generate a lot of heat. In order to make electronic products work normally for a long time, electronic products must have the function of self-dissipating heat. Among them, the cooling fan It is one of the most widely used cooling devices for electronic products. In order to extend the life of the cooling fan, the usual cooling fans use double ball bearings, because the ball bearings have rolling friction and the friction is small. However, the use of double ball bearings is costly, and one of the ball bearings fails. Failure, the probability of failure is high. Contents of the invention [0003] Based on this, it is necessary to provide a heat sink with reliable structure and long service l...
