The small electric generating set adopts the radiating fan to isolate the engine and the generator, so that heat which is generated when the engine and the generator works can not be gathered at the place of the radiating fan; radiating air flow can flow according to the predetermined direction, path and speed; the ventilation and radiation efficiency of the electric generating set can be effectively improved; the electric generating set can be maintained at a lower working temperature; and the working efficiency of the engine and the generation efficiency of the generator can be feasibly guaranteed and improved.
Description
Invention field
The present invention relates to a kind of small power generation unit of forming by motor and generator, specially refer to the small power generation unit of forming by diesel engine or petrol engine and magneto-electric generator.
Background technique
The small power generation unit of prior art is made up of diesel engine or petrol engine (below be referred to as motor) and excitation-type generator or magneto-electric generator (below be referred to as generator) usually.For reducing the volume of generator set, reduce raw materials consumption, usually be one with motor and generator designs, be about to the rotor of generator or the end that stator is directly installed on the engine rotation axle, that have even direct is one with the rotor of generator and the flywheel design of motor.Like this, both reduce raw-material use amount, reduced the shared space of whole unit again.When generator set was worked, motor and generator all can produce a large amount of heats.And the generating efficiency of efficiency of engine and generator all has crucial the contact with self temperature.Along with the rising of temperature, the generating efficiency of efficiency of engine and generator all sharply descends thereupon.If the employing magneto-electric generator, along with the rising of temperature, permanent magnet may produce demagnetization effects, the power generation performance of grievous injury generator, serious also can make permanent magnet lose magnetism can, make generator lose power generation performance.
For reducing the operating temperature of small power generation unit, prior art normally increases radiation fan at an end of generator set, and fan blade is directly installed on the rotatingshaft of motor, perhaps is installed on the generator rotor shafts.During engine rotation, the radiation fan blade rotates thereupon together, plays the effect of heat radiation.But, because motor and generator all can produce heat during generator set work, prior art links together both can make heat accumulation, and both heats can only loose from the surface row that cooling air flows, and more heat then may accumulate in both connecting parts.In addition, because prior art only is an end that radiation fan is provided with generator set, do not adopt other measures to set heat radiation distinguished and admirable flow direction, path and flow velocity, it is distinguished and admirable very limited from motor and the out-of-date heat of taking away of generator table surface current to dispel the heat, motor and generator produce a large amount of heats when being not enough to get rid of generator set work, still are in higher temperature during generator set work.
Summary of the invention
For improving the result of ventilating heat dissipation of small power generation unit, reduce the operating temperature of motor and generator, improve the working efficiency of generator set, the present invention proposes a kind of radiation fan to be arranged between motor and the generator, and at the small power generation unit of the outer installment heat radiation outer cover of generator set.Small power generation unit of the present invention adopts radiation fan that motor and generator are isolated, the heat that makes when both work to be produced can not assembled at this, and can make heat radiation distinguished and admirable mobile according to predetermined direction, path and speed, effectively improve the ventilation and heat efficient of generator set, make generator set can keep lower operating temperature, guarantee and improve the generating efficiency of efficiency of engine and generator conscientiously.
Small power generation unit of the present invention is arranged on radiation fan between motor and the generator, and at the outer installment of generator set heat radiation outer cover, the heat radiation outer cover is provided with intake grill and exhaust outlet.
The radiation fan of small power generation unit of the present invention can be an axial-flow type radiator fan, also can be the radial-flow type radiation fan.
The heat radiation outer cover of small power generation unit of the present invention can be an integrated type heat radiation outer cover, also can be split type heat radiation outer cover.
