Description
Technical field
The present invention relates to a kind of structure of field of photovoltaic power generation gird-connected inverter more particularly to a kind of photovoltaic power generation grid-connecting are inverse
Become the shell of device.
Background technology
Component in photovoltaic generation has its operating temperature ratings, especially as grid-connected inverter, has
Heat dissipation performance is poor, and with inverter continue working, for the heat transfer of component less than the external world, temperature will be higher and higher.It is special
It is not in the case of sunlight prolonged exposure, temperature can be stepped up, if venting practice is bad, cause temperature excessively high, will
It reduces component performance and the service life ensures it to keep inverter internal component operating temperature in rated temperature range
Efficiency and service life, it is necessary to Heat Conduction Material comes out inverter internal heat transfer,
For heat transfer angle, inverter internal and external temperature is more balanced, i.e. inner heat component and radiator, shell temperature
Spend closer, thermal energy conduction is better.If inverter is cold outside and hot inside, it is meant that inverter heat dissipation performance is not excellent.This is with regard to class
Like the relationship of thermal insulation cup and ordinary cup：
Invention content
The technical problem to be solved by the present invention is to provide that a kind of efficiency is higher and energy consumption is smaller, lower-cost photovoltaic hair
The shell of electric gird-connected inverter.
In order to achieve the above object, the technical scheme is that a kind of shell of photovoltaic power generation grid-connected inverter, including it is outer
Frame and radiator structure, the outline border constitute the basic shell of inverter, and the radiator structure includes heat absorption strip and heat sink strip,
The heat absorption strip and heat sink strip arrangement that intersects is fixed on the outline border, and described here is fixed on outline border, can be with
Common it is connected and fixed mode by the way that gluing, or clamping, screw etc. are various.The outline border side is dismountable fixed
Each functional component of side, the affixed side and inverter connects, and affixed side can both serve as the effect of backboard, and can also pass through
Each functional component is fixed on backboard, then backboard is fixed in affixed side by other modes, the affixed side in the present invention
It can be designed to various patterns according to weather conditions, using hollow out or good Heat Conduction Material, be conducive to radiate in this way.The inversion
Device shell belongs to passive heat radiation, and consume energy larger device without water pump etc., saves energy consumption, reduces cost.
Preferably, each functional component of the inverter is fixed on backboard, and the backboard is fixed on the outline border
Affixed side.Affixed side is preferably engraved structure, is conducive to the circulation of air in this way.
Preferably, there is the backboard screw hole, the affixed side there is screw hole, the backboard to be fixed by screws in
In the affixed side, the screw hole of the affixed side is convex.Certain gap is formed between backboard and affixed side in this way, favorably
In heat dissipation.
Preferably, the heat absorption strip is the heat absorption strip made of phase-change material.By Heat Conduction Material by the heat of heat generating member
Amount imports inverter shell and absorbs heat by phase-change material simultaneously, passes through the thermostatic characteristics control device temperature of phase transition process.
Preferably, the heat sink strip is the heat sink strip made of metal or carbon fiber or graphite.It is led with good
It is hot.
Preferably, the outline border is outline border made of aluminum material.Cost is relatively low, slight low, and with good
Heat conductivility, energy accelerated heat is from heat generating member to the conduction of inverter shell.
The invention has the advantages that：Inverter shell belongs to passive heat radiation, consumes energy without water pump etc. larger
Device saves energy consumption, cost is reduced, especially for northwest extreme climate environment, the materials such as aluminium
Description of the drawings
In order to illustrate more clearly of the present invention, will simply be situated between to attached drawing needed in embodiment description below
It continues.It should be evident that the accompanying drawings in the following description is only the description to the embodiment of the present invention, for ordinary skill
For personnel, without having to pay creative labor, simple deformation or title can also be carried out according to technical solution
Variation, or customary means is taken, it can also realize goal of the invention.

Specific implementation mode
With reference to embodiment, the present invention is described in further detail, following embodiment be explanation of the invention and
The invention is not limited in following embodiments.
As shown in Figure 1 and Figure 2, present embodiment discloses a kind of shell of photovoltaic power generation grid-connected inverter, the inverters
Shell includes outline border 1 and radiator, and the radiator includes heat absorption strip 3 and heat sink strip 2, the heat absorption strip 3 and is dissipated
Hot item 2 intersects arrangement, and there are one affixed sides 5 for the outline border 1 tool, are not shown in fig. 2, the back of the body is fixed in affixed side 5
Plate 4, the functional component of photovoltaic power generation grid-connected inverter, is all welded on backboard, and the heat absorption strip 3 is by phase-change material system
At heat absorption strip, the heat sink strip 2 be the heat sink strip made of metal or carbon fiber or graphite, the outline border be aluminum material
Outline border made of material.
Heat generating member since operation is generated heat, by after the heat importing inverter shell of heat generating member inhale by the heat absorption strip of radiator
The phase-change material of hot item absorbs heat storage, and phase-change material is gradually converted into liquid by solid-state, to reduce the temperature of heat generating member.
Due to air themperature be less than phase-change material temperature, phase-change material automatically will storage heat by heat sink strip heat release to air in,
Restore to original state (solid-state).Next time, realization recycled in use, the radiator can absorb heat again.
