Description

A kind of air-cooled unit of compact

Technical field

The utility model is related to a kind of motor, particularly relates to a kind of air-cooled unit of compact.

Background technology

Existing generating set, to realize to the radiating in cabinet, often installs ventilating fan, because of air draft on the two side of cabinet Fan is set independently of generator and power set, when generating set works, it may appear that ventilating fan is damaged and generator and power dress The situation of normal work is put, now the radiating effect in cabinet is to be guaranteed, separately because installing space is limited, ventilating fan Volume, power are typically small, and the radiating effect in cabinet is poor, and then are easily caused generator and power set damage.To solve Above mentioned problem, proposes to fix case radiation fan on the generator shaft outside generator, in cabinet, case radiation fan is by generating electricity Machine is direct, power set drive indirectly, although this can ensure the uninterrupted radiating during power set and generator operation, and phase Than the small-sized ventilating fan installed in traditional case side wall, the case radiation fan power driven indirectly by power set is bigger, dissipates Thermal effect is more preferable, but its requirement extends to generator shaft outside generator, and case radiation fan need to be installed in cabinet, this On the basis of present generating set, the volume and quality of generating set are considerably increased, and then limits generating set in body Product and the application in the small place of quality requirement.

The content of the invention

The purpose of this utility model is to provide a kind of air-cooled unit of compact.

A kind of air-cooled unit of compact, including cabinet, the power set that adjacent coaxial is connected in cabinet and generating Machine, the one end of motor of generator axle away from power set extends to outside generator but does not pass cabinet, extends to outside generator Fix a case radiation fan in motor shaft extension section, the generator include the pcb board stator being coaxially disposed with motor shaft and Electronic module, the both sides of the pcb board stator are symmetrical and are outwards sequentially provided with magnetic steel rotor, radiation shell and end cap respectively, described Radiating valve jacket is fixed on motor shaft, and end cap is rotatably sheathed on motor shaft, and the first mounting groove is provided with the middle part of the end cap, single The radiation shell of side be located at in the first mounting groove of the end cap of its homonymy, the radiation shell on the one side of end cap along its justify Week is provided with the first dividing plate of some radially scattered distributions, on the end face of the mounting groove of end cap first along its circumference insertion provided with it is some enter Air port, the first mounting groove of end cap circumferential side wall is provided with the air outlet of some insertions, and end cap is provided with the second mounting groove, the electricity Submodule is located in the second mounting groove, and the magnetic steel rotor is distributed and fixed along radiation shell even circumferential, the two end cap assembling It is fixedly connected.
