Description

Generator set with high heat dissipation performance

Technical Field

The utility model relates to the field of engines, in particular to a generator set with high heat dissipation performance.

Background

The generator refers to a mechanical device for converting other forms of energy into electric energy, which is driven by a water turbine, a steam turbine, a diesel engine or other power machines, converts energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy, transmits the mechanical energy to the generator, and then converts the mechanical energy into electric energy by the generator. The existing generator set generally comprises a stand, a driving mechanism and a stator-rotor component, wherein the driving mechanism and the stator-rotor component are arranged in the stand, the driving mechanism drives the rotor to rotate, and after the driving mechanism and the stator are used as magnetic cutting lines, electric energy is output through voltage regulator conversion. Because the rotor runs at a high speed, larger heat can be generated, and a fan radiating mechanism is further arranged in the generator and comprises an impeller and a wind scooper, when the generator radiates heat, the cold air enters the stator and the rotor through the wind scooper after external cold air is introduced from one side close to the impeller (specifically, cold air is introduced from the tail cover of the generator shell), and finally is discharged through an air outlet on the wind scooper.

Besides the generator heat dissipation mechanism, the existing generator set is also provided with a control panel assembly which is in a box structure, and a plurality of control electronic components are arranged in the control panel.

Therefore, the control panel needs to be cooled based on the original generator. However, in the existing control panel heat dissipation mechanism, a driving motor is generally added in the control panel, after the fan blades connected with the driving motor are driven to rotate by the driving motor, the fan blades blow and suck air into the control panel box body, so that the air flow in the device is quickened, and the heat dissipation speed and heat dissipation efficiency are improved. Above-mentioned radiating mode to control panel needs to add driving motor and flabellum, and cooling mechanism needs great installation space, and current generating set corresponds control panel position installation space less, simultaneously, this cooling mechanism can increase use cost.
