Detailed description of the invention
It, below will be to the utility model embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing needed in description is briefly described.
Fig. 1 is a kind of phase-change radiation system for photovoltaic DC-to-AC converter that the utility model embodiment provides.
Specific embodiment
The technical issues of to solve the utility model, the technical solution of use and the technical effect that reaches are clearer,
It is described in further detail below in conjunction with technical solution of the attached drawing to the utility model embodiment.
As shown in Figure 1, present embodiment provides a kind of phase-change radiation system for photovoltaic DC-to-AC converter, it mainly include inside cabin
1, air-cooled cabin 2, internal circulating fan 3, condensation cooling fin 4 and Evapotranspiration backing 5, air-cooled cabin 2 is fixed on the side of inside cabin 1, cold
Hollow inside solidifying cooling fin 4 and Evapotranspiration backing 5, condensation cooling fin 4 is arranged inside air-cooled cabin 2, and Evapotranspiration backing 5 is arranged
Inside inside cabin 1, the lower end of condensation cooling fin 4 is connected with the upper end of Evapotranspiration backing 5, and the also phase of the hollow space inside the two
It connects, internal circulating fan 3 is fixed on the inside of inside cabin 1.Preferably, present embodiment is additionally provided in the upper end of inside cabin 1
Outside air inlet cabin 6, the setting in outside air inlet cabin 6 can be improved the sealing grade of inside cabin 1, it is external enter the wind cabin 6 also with air-cooled cabin 2
Upper end is connected with each other, and in order to faster and better realize the flowing of external wind, present embodiment is in outside air inlet cabin 6 and air-cooled
External cooling blower 7 is provided between cabin 2.In the present embodiment, condensation cooling fin 4 is angularly disposed inside air-cooled cabin 2,
Lower one end of condensation cooling fin 4 is fixed at the connecting portion of air-cooled cabin 2 and inside cabin 1, and higher one end is fixed on wind
