Abstract
The invention discloses closed self-circulation conductive radiator liquid for a solar photovoltaic module and a preparation method for the radiator liquid. The closed self-circulation conductive radiator liquid is mainly prepared by the following steps of: sequentially adding diethyl ether, carbon disulfide, acetone, methanol, ethanol and isopropyl alcohol into a mixing kettle, stirring and mixing; and performing secondary filtering by using a filter to remove impurities. The closed self-circulation conductive radiator liquid can effectively reduce the temperature of the solar photovoltaic module.

Technical field
The invention belongs to the cooling fluid technical field, particularly a kind of solar photovoltaic assembly sealing self-loopa heat loss through conduction liquid and preparation method thereof.
Background technology
Along with the popularity rate of solar-energy photo-voltaic cell improves constantly, the user is also more and more higher to every index request of solar photovoltaic battery component, the generating efficiency of utilizing various effective methods to improve solar photovoltaic assembly is a pendulum urgent day by day problem in face of people, because when solar-energy photo-voltaic cell produces photovoltaic generation work in the sun, in photoelectric conversion process, can discharge some heats, sunlight also can produce some heats to the irradiation on solar photovoltaic assembly surface simultaneously, these heats are very big to generating efficiency and the life-span influence of solar-energy photo-voltaic cell, the temperature of utilizing coolant to reduce solar photovoltaic assembly can improve the generating efficiency of solar photovoltaic battery component to a certain extent and prolong the life-span of photovoltaic module, the best theoretical temperatures of solar-energy photo-voltaic cell is 25 ° Celsius, because the variation that temperature raises has the influence that causes the pass for generating efficiency and the life-span of solar-energy photo-voltaic cell, so the working temperature of reduction solar photovoltaic battery component is to improve generating efficiency, prolong the life-span of solar photovoltaic assembly, utilize abundant green energy resource product significant scientificly.
Summary of the invention
The objective of the invention is to, solar photovoltaic assembly sealing self-loopa heat loss through conduction liquid of a kind of effective reduction solar photovoltaic assembly temperature and preparation method thereof is provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of solar photovoltaic assembly sealing self-loopa heat loss through conduction liquid, and it mainly is to be made by following raw materials by weight percent: ether 20%～40%, carbon disulfide 2%～22%, acetone 6%～26%, methyl alcohol 10%～30%, ethanol 6%～26%, isopropyl alcohol 1%～16%;
In the above-mentioned solar photovoltaic assembly sealing self-loopa heat loss through conduction liquid formulation, the consumption of each raw material calculates according to percentage by weight, is preferably: ether 30%, carbon disulfide 12%, acetone 16%, methyl alcohol 20%, ethanol 16%, isopropyl alcohol 6%.
The preparation method of above-mentioned solar photovoltaic assembly sealing self-loopa heat loss through conduction liquid: get ether, carbon disulfide, acetone, methyl alcohol, ethanol, isopropyl alcohol and add mixing kettle successively and mix, utilize filter to carry out getting final product after cascade filtration is removed impurity then.
The present invention utilizes the cooling fluid of some kinds of different boiling solvent compositions to the tangible characteristic of different temperatures zone induction, by the back mounted heat dissipation metal injection the present invention of system at solar module, when solar photovoltaic assembly is worked under different ambient temperatures, certain solvent that is installed in the intrasystem the present invention's prescription of heat dissipation metal can reach mobile until vaporized state according to photovoltaic module different operating temperature, by the heat dissipation metal system solvent of inner ebullition is dispelled the heat again, be implemented under the different temperature conditions purpose to assembly radiating.The preparation process of cooling fluid: according to following prescription ether, carbon disulfide, acetone, methyl alcohol, ethanol, the isopropyl alcohol of technical grade added mixing kettle successively and mix, utilize filter to carry out namely becoming finished product after cascade filtration is removed impurity then
The present invention realizes that according to the material that adopts different boiling photovoltaic module is at the varying environment temperature conditions, utilize the solvent material of different boiling in the composition of filling a prescription after meeting different temperatures, to produce volumetric expansion or gasification, make it in the mobile purpose that realizes the solar photovoltaic assembly heat radiation of the inner generation of cooler.When working under temperature conditions Celsius 35 ℃ as photovoltaic module, the ether solvent boiling point of cooling liquid formulation inside is 34.51 ℃ Celsius, under this temperature, ether solvent produces volumetric expansion or gasification, ether solvent is expanded in the cooler inner volume, in cooler, form flow regime and take away heat to reach, realize the purpose of photovoltaic module cooling.
The characteristic that the present invention utilizes the solvent of different boiling to seethe with excitement under condition of different temperatures, when photovoltaic module was worked in the normal temperature conditions scope, the effect of giving full play to the different boiling solvent reached the purpose that photovoltaic cell is dispelled the heat.Utilize product of the present invention not only can make photovoltaic module be issued to operate as normal in the temperature conditions of higher, and also can normally use in the winter time, can reach the purpose that normally to use throughout the year.
Because the present invention is the mixed solvent that adopts different boiling, because adopting multiple solvent forms according to different ratios, can prevent the excessive expansion of low boiling point solvent under the higher environment of temperature effectively, mixed solvent is at airtight metal heat sink internal work simultaneously, there is not omission, non-volatile in the course of work, but long-time running does not need to replenish at any time.
