Description
Technical field
The utility model relates to a kind of photovoltaic DC-to-AC converter structure, particularly a kind of cooling system that is used for the high-power heater members cooling of photovoltaic DC-to-AC converter.
Background technology
The storage of electric energy will solve a lot of problems.At present method in common is generated electricity by way of merging two or more grid systems the photovoltaic electric energy exactly through inverter, when needs use electric energy again to the electrical network power taking.One of them important problem is the conversion efficiency of inverter in the electric energy transfer process, and the loss of inverter is dispersed with the form of heat.The heat that the high-power heater members loss of high power contravariant device is produced can improve the use cost of components and parts widely, the useful life that can reduce components and parts in the inverter again greatly simultaneously.Therefore, how solving the heat dissipation problem of high power contravariant device, is to improve the inverter key issue in useful life.
In general, the peak efficiencies of the inverter of non-isolated power output can reach 96-97%.The power output of supposing inverter is 100KW, and the power loss of this inverter can reach 400W.If add the mode that fan forces heat radiation by traditional metal heat sink; Following problem is then arranged: (1) is because the area of metal heat sink is limited; Make radiating effect limited; If will certainly will cause the volume of metal heat sink to strengthen through the mode of increased area, bring inconvenience such as machine weight increase, machine volume increase; (2), can only be through the increase rotating speed, and the easy like this reliability that causes reduce, and makes that the life-span of inverter is influenced if will improve the radiating effect of powerful fan; (3) above 2 can be caused the temperature of cabinet inside still higher, and in this case, the components and parts of selecting for use must can adapt to higher ambient temperature, cause cost to improve.
Heat conducting mode has 3 kinds, i.e. radiation, convection current, evaporation.Radiation, convection current are traditional radiating modes, in the small power electric source device, are efficient ways.Along with the raising of power-supply device use power, although power-supply device has very high conversion efficiency,, the various power losss of circuit all can outwards be dispersed with the form of heat.Present radiator all is to dispel the heat with the mode of radiation, convection current.This radiating mode can not reduce the inner heat of large power supply equipment machine timely and effectively.When if the summer environment temperature is very high, although can improve to the radiator of this form,, fundamentally still can not tackle the heat radiation requirement that increases the power-supply device of power day by day at present.
From radiating principle, this type radiator all belongs to passive heat radiation, and radiating efficiency is not high, can not be fundamentally the temperature of machine intimate be dropped to ambient temperature or below the ambient temperature.
On the other hand; Present inverter radiator structure; Generally be that the evaporator heat-absorbent surface is fully contacted with high-power heater members, the heat that produces when high-power like this heater members is worked is evaporated device and absorbs, and is distributed by the opposite side of evaporator and the heat exchange of external environment.Yet the radiating effect of this structure also can receive the influence of ambient temperature except receiving the volume restrictions of evaporator; According to heat exchange principle, we know that heat always shifts to the low place of temperature from the high place of temperature, and temperature difference is big more; Transfer velocity is fast more, like this, if the residing ambient temperature of inverter when higher (like summer outdoor); Will cause heat to distribute, thereby shorten the useful life of inverter greatly.
Based on above consideration, the design people studies improvement to the existing inverter radiator structure, and this case produces thus.
