Embodiment
As shown in Figure 1, the temperature-adjusting device 20 of photovoltaic module of the present invention can be installed on photovoltaic generating system 100.This photovoltaic generating system 100 can comprise the photovoltaic modulies 10 of connecting or being connected in parallel together of organizing more.In this execution mode, be that to be with the photovoltaic module that is connected in parallel that example is explained of the present invention.
Like Fig. 1 to shown in Figure 4, the controller 25 that the temperature-adjusting device 20 of photovoltaic module of the present invention comprises the conductive structure 21 that is installed in photovoltaic module 10 back sides, the heat pipe 22 that is connected with conductive structure 21, be connected also buried radiator 23 with heat pipe 22, be installed in circulating pump 24 on the heat pipe 22, work in order to the temperature sensor (scheming not show) and the may command circulating pump 24 of detected light photovoltaic assembly 10 temperature.
Said conductive structure 21 is the tabular or the membranaceous back side that is tiled in photovoltaic module 10.Said conductive structure 21 is fixedly connected with photovoltaic module 10 through heat-conducting glue 30, thereby the heat extraction of photovoltaic module 10 is come out.The material of said conductive structure 21 is to have the metal material of high thermal conductivity or the mixture of metal material and organic material.
Said heat pipe 22 is back-shaped pipe, is cylinder or multi-faceted column structure.Said heat pipe 22 perhaps welds through heat-conducting glue or the close mechanical contact structures are able to be fixedly connected with conductive structure 21.Said heat pipe 22 is processed by a kind of material in copper, aluminium, stainless steel or the pottery.Artificial anti-icing fluid or other low freezing point working medium are housed in the said heat pipe 22.Also be provided with on the frame of said photovoltaic generating system 100 and recycle inlet 11, thereby this recycles inlet and through outside heat pipe 22 the back-shaped heat pipe 22 in inside is connected to circulating pump 24.
Like Fig. 3 and shown in Figure 4, said radiator 23 is imbedded underground and is processed by one or more or its mixture in corrosion resistant organic material, metal material or the ceramic material.Subsurface temperature depends primarily on its distance, season of living in, geologic structure and soil constituent from the face of land.Underground below 20 meters, the soil moisture is close with face of land year-round average temperature value, and receives hardly that ambient temperature is periodically variable to be influenced, and annual temperature is in steady state basically.When summer, ground was the hottest, the soil moisture at underground 0.8 meter about 25.0 ℃, the soil moisture at 1.6 meters is about 21 ℃.In general geologic structure, the annual temperature at following 0.8 meter, the face of land is the highest can be above 30 ℃.Therefore with the buried degree of depth of radiator for the annual temperature that can guarantee radiator 23 environment of living in more than or equal to 0.8 meter is the highest can be above 30 ℃.
