Description
Technical field
Power inverter technical field is the utility model is related to, more particularly to a kind of modular power converters.
Background technology
In power inverter, heat dissipation technology is an extremely important ring, because electronic component is at work in housing
Substantial amounts of heat can be produced, if these heats cannot timely exclude that electronic component will be damaged.General power conversion
Device can all carry fan assembly, for discharging the heat in housing.But often fan assembly well can not exclude heat
Go, residual heat is easily produced in housing cavity.
Utility model content
The purpose of this utility model is to provide a kind of modular power converters so that the thermal current in housing can be very square
Just housing is dredged out.
What the purpose of this utility model was realized in：A kind of modular power converters, including housing, be placed on housing
Fan assembly, internal portioning layer is provided with the housing, the internal portioning layer closes on housing upside, and the internal portioning layer is by housing
Chamber is divided into the upper separate space mutually completely cut off, main inner chamber, and all electronic components are arranged in main inner chamber, and the upper separate space volume is small
In main inner chamber volume, the upper separate space is in above main inner chamber；The fan assembly is arranged on the upside of main inner chamber, in the housing
Chamber side wall is provided with main venthole, the main venthole of outlet air end face of the fan assembly；The internal portioning layer lower surface is provided with can
Thermal current is guided into the guide curve surface of the suction side of fan assembly；A plurality of air admission hole, the air admission hole are provided with the downside of the housing
It is connected with main inner chamber；The housing sidewall top is provided with the top venthole being conducted with upper separate space.
Compared with prior art, the beneficial effects of the utility model are：It is easy to discharge the heat in housing, during heat extraction,
Start fan assembly, form one and flow through air admission hole, main inner chamber, fan assembly, the air-flow of main venthole successively, wherein, inside
Under the guiding function of the guide curve surface of interlayer, thermal current can be oriented to the suction side of fan assembly, so as to which thermal current is discharged into housing,
Thermal current will not four dissipate, the flowing of thermal current has directionality, so as to which thermal current is dredged out into housing；Upper separate space leads to main inner chamber
Cross internal portioning layer to separate, prevent hot gas to be flowed into separate space, and the heat in upper separate space can be discharged by top venthole,
Be not in therefore, in upper separate space too many heat because electronic component is not arranged in upper separate space.
As preferred scheme of the present utility model, the internal portioning layer is made up of flame retardant type material.Prevent internal portioning layer by heat
Scorch deformation.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model.
Wherein, 1 housing, separate space on 101,102 main inner chambers, 103 air admission holes, 104 top ventholes, 105 main ventholes, 2
Fan assembly, 3 internal portioning layers, 3a guide curve surfaces.
Embodiment
As shown in figure 1, a kind of modular power converters, including housing 1, the fan assembly 2 that is placed on housing 1, housing 1
Interior to be provided with internal portioning layer 3, internal portioning layer 3 closes on the upside of housing 1, and the inner chamber of housing 1 is divided into the upper separate space mutually completely cut off by internal portioning layer 3
101st, main inner chamber 102, all electronic components are arranged in main inner chamber 102, and the upper volume of separate space 101 holds less than main inner chamber 102
Product, upper separate space 101 are in the top of main inner chamber 102；Fan assembly 2 is arranged in the upside of main inner chamber 102, is set on the intracavity sidewall of housing 1
There are main venthole 105, the main venthole 105 of outlet air end face of fan assembly 2；The lower surface of internal portioning layer 3, which is provided with, to draw thermal current
To the guide curve surface 3a of the suction side of fan assembly 2；The downside of housing 1 is provided with a plurality of air admission hole 103, air admission hole 103 and main inner chamber
102 are connected；The side wall upper part of housing 1 is provided with the top venthole 104 being conducted with upper separate space 101.
Above-mentioned internal portioning layer 3 is made up of flame retardant type material.
During heat extraction, start fan assembly 2, form one and flow through air admission hole 103, main inner chamber 102, fan assembly 2, master successively
The air-flow of venthole 105, wherein, under the guide curve surface 3a of internal portioning layer 3 guiding function, thermal current can flow to fan assembly 2
Suction side, so as to by thermal current discharge housing 1.
The utility model is not limited to above-described embodiment, on the basis of technical scheme disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour can is special to some of which technology
Sign makes some and replaces and deform, and these are replaced and deformed in the scope of protection of the utility model.
