Description
Technical field
It the utility model is related to a kind of generating set inverter cooling device.
Background technology
Generating set is mainly made of engine, generator and electric-control system, the chemical energy of fuel oil can be converted into electric energy.
Compared with traditional power frequency Synchronous generator, there is efficient, weight using the inverter generator group of multi-polar permanent-magnet generator
Gently, the advantages that output voltage waveforms quality is high, represents the developing direction of small power generation unit.Core in inverter generator group
Electric component is inverter (also referred to as frequency converter), and inverter uses the converter technique of Switching Power Supply, and multi-polar permanent-magnet generator is defeated
The medium frequency alternating current gone out is converted to the industrial-frequency alternating current of voltage stabilization.Inverter at work, the work(such as rectifier, IGBT and inductance
Rate device can generate heat, and since these devices are more sensitive to temperature, once temperature exceedes License Value, inverter may be burnt
Ruin, cause whole generating set thoroughly to paralyse, therefore the cooling and heat dissipation of inverter are extremely important.
The content of the invention
The purpose of this utility model is to provide a kind of generating set inverter cooling device, and not only cooling effectiveness is high for it,
And it can effectively reduce the horizontal volume of generating set.
The purpose of this utility model is achieved through the following technical solutions：A kind of generating set inverter cooling device, it is wrapped
The cooling fan driven by engine crankshaft, the wind scooper arranged on cooling fan periphery are included, is installed on the upside of wind scooper and connects
Inside wind scooper and the cooling ventilation duct of outside air and the inverter that is arranged on cooling ventilation duct；The cooling ventilation duct
Vertically arranged, inverter is arranged on cooling ventilation duct at side-inlet.
For the prior art, the utility model has the advantage of：
1. inverter is arranged on the upside of wind scooper by the utility model, cooling wind is oriented to by auxiliary air inlet road,
So that the wind of cooling fan inspiration can cool down inverter side comprehensively, inverter position, which is set, in addition can reduce generator
The horizontal volume of group, convenience in transport.
2. inverter is arranged on the upside of wind scooper, facilitates cooling device to draw cooling wind from away from fever center, carry
High cooling efficiency.
3. leave oblique inlet air gap between inverter side wall and auxiliary air inlet road side wall, the section in oblique inlet air gap by
It is gradually reduced under, oblique inlet air gap setting can increase intake velocity, improve cooling effect.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of generating set inverter cooling device embodiment of the utility model.
Fig. 2 is the sectional view of generating set inverter cooling device.
Fig. 3 is the section view of generating set inverter cooling device.
Label declaration：1 cooling fan, 2 wind scoopers, 3 cooling ventilation ducts, 4 inverters, 5 auxiliary air inlet roads, 6 oblique inlet airs
Gap, 7 transverse air-intake gaps.
Embodiment
The utility model content is described in detail with reference to Figure of description and embodiment：
Illustrated as shown in Figure 1 to Figure 3 for a kind of implementation of generating set inverter cooling device provided by the utility model
It is intended to.
A kind of generating set inverter cooling device, it is included by the cooling fan 1 of engine crankshaft drive, arranged on cooling
The wind scooper 2 of 1 periphery of fan, be installed in the upside of wind scooper 2 and the cooling ventilation duct 3 of 2 inside of connection wind scooper and outside air
And it is arranged on the inverter 4 on cooling ventilation duct 3；The cooling ventilation duct 3 is vertically arranged, and inverter 4 is arranged on cooling channel
On road 3 at side-inlet.
Inverter 4 is arranged on the upside of wind scooper 2, facilitates cooling device to draw cooling wind from away from fever center,
Cooling effectiveness is improved, in addition, generating set can be used to house inverter 4 by reserving a part of space in fuel tank downside, from
And reduce generating set transverse direction volume, it is readily transported.
Auxiliary air inlet road 5 is set at the upper side-inlet of the cooling ventilation duct 3, and the auxiliary air inlet road 5 is funnel-form
Structure, inverter 4 are erected at 5 upside entrance of funnel-form auxiliary air inlet road.
Oblique inlet air gap 6 is left between 4 side wall of inverter and 5 side wall of auxiliary air inlet road, oblique inlet air gap 6
Section is from top to bottom gradually reduced.Oblique inlet air gap 6, which is set, can increase intake velocity, improve cooling effect.
Transverse air-intake gap 7 is left between the downside of 4 bottom of inverter and auxiliary air inlet road 5, transverse air-intake gap 7 connects
Logical cooling ventilation duct 3 and oblique inlet air gap 6.Transverse air-intake gap 7 is so that 4 bottom of inverter also can preferably be cooled down.
Arrow show the flow direction of cooling wind in Fig. 1, and cooling wind enters from auxiliary air inlet road 5, successively by oblique inlet air
Gap, transverse air-intake gap, cooling ventilation duct, wind scooper, eventually enter into generating set.Wind is cooled down to flow in auxiliary air inlet road
When, the heat on inverter 4 can be taken away, so as to be cooled down to inverter 4.
4 face cooling fan 1 of inverter is set in conventional electric power generation unit, and directly inverter 4 is blowed by cooling fan 1
Wind is cooled down, not only easily produces sinuous flow, cooling effect is poor, and can increase the horizontal volume of generating set, not readily transportable.
