The side face of the reactor body is provided with a heat dissipation device. The heat dissipation device comprises a heat end and a cool end. The heat dissipation device mainly consists of a plurality of evaporating tubes and a cooling box. One end of each evaporating tube is arranged in the cooling box to form the cooling end and the other end of each evaporating tube forms the heat end. The utility model has the advantages that the heat exchange but the cooling is carried out on the air in the inverter box and the external air so as to prevent the impurities including dust, smoke, moisture, sea salt and the like in the external environment from influencing the reactor and effectively ensure the working environment and the heat dissipation effect of the reactor. The service life is prolonged and the effect is enhanced.
Description
Technical field
The utility model belongs to the inverter field, and especially a kind of radiating effect well is used for the reactor of inverter.
Background technology
Along with crystal silicon solar batteries high efficiency, the development of sheet technology and emerging in large numbers of novel thin film solar cell, solar photovoltaic generation system cost and the electric cost of degree descend significantly, and its application has entered the new stage to large-scale development.Global photovoltaic generating system installation had reached 6.43GW in 2009, and Chinese installation reaches more than the 160MW, was equivalent to the sum total of installation over the years.
In solar photovoltaic generation system, for realizing system high efficiency, stable and safe operation, inverter is the most key equipment, and particularly in the large-sized photovoltaic grid-connected system, the apolegamy of high-power combining inverter is the primary judgement symbol that photovoltaic plant is built success or failure.But the electronics of present nearly all high power contravariant device, the electrical control components and parts all are placed in the cabinet casing with a constant volume, the heat that they are produced in running, often set up louvre and fan to electronics by cabinet, electric elements carry out cooling heat dissipation, this heat dissipating method is because casing is open relatively, so dust in the external environment, smog, impurity such as moisture content and even sea salt particle are bigger to the influence of reactor, easily attached to the reactor surface, make that the reactor radiating effect is poor, if but the inverter casing is made closed type, adopt the fan radiating effect also bad.
Summary of the invention
The purpose of this utility model provides a kind of good heat dissipation effect, can carry out the reactor of steady operation in airtight inverter casing, and this reactor has solved the impurity such as dust, smog, moisture content and even sea salt particle that are subjected to easily in the above-mentioned technology in the environment to the influence of reactor and the shortcoming of weak heat-dissipating.
The technical scheme that realizes the utility model purpose is as follows:
The reactor that is used for inverter, it comprises the reactor body, this reactor also comprises the heat abstractor that is located at its body side, this heat abstractor comprises hot junction and cold junction, heat abstractor mainly is made of some steaming pipes and cooler bin, some steaming Guan Yiduan are located at and become cold junction in the cooler bin, and the other end of some steaming pipes becomes the hot junction.
Described steaming inside pipe wall is provided with some grooves.
The gravity assisted heat pipe that described steaming pipe is a vacuum or steam pipe for annular.
Described groove is linear pattern or is spirality that its cross section is trapezoidal.
Adopted such scheme, the reactor that is used for inverter, coolant is established in the hot junction in the gravity assisted heat pipe, establish cooling fluid in the cooler bin, the boiling point of cooling fluid is lower than coolant, reactor is with the heat transferred gravity assisted heat pipe that produces, gravity assisted heat pipe is with the heat transferred coolant that absorbs, coolant heat absorption back gasification, the coolant of gasification rises to cold junction, be subjected to the cooling fluid condensation in the cooler bin, coolant liquefies then, arrives the hot junction of gravity assisted heat pipe by the gravity reflux of self, continue as cocycle, from cooling, need not to cool off like this, especially need not the air in the inverter casing and outside air to be carried out heat exchange and cool off by external force, prevented the dust in the external environment, smog, impurity such as moisture content and even sea salt particle are to the influence of reactor, the operational environment of the reactor of Bao Zhenging and radiating effect prolong its useful life effectively, and effect strengthens.

Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the reactor that is used for inverter, it comprises reactor body 1 and heat abstractor, heat abstractor is installed in reactor body 1 side, heat abstractor mainly is made of with cooler bin 3 some gravity assisted heat pipes 2, this gravity assisted heat pipe 2 is a vacuum, gravity assisted heat pipe 2 one ends are located at and form cold junction in the cooler bin 3, the other end is the hot junction, cooler bin 3 is interior by import 31 and outlet 32 circulation cooling fluids, hot junction in the gravity assisted heat pipe 2 is provided with coolant, the boiling point of cooling fluid is lower than the boiling point of coolant, coolant is used for absorbing the heat that is passed to gravity assisted heat pipe 2 by reactor, flow to the cold junction of gravity assisted heat pipe 2 after the gasification, heat in the coolant after the cooling fluid of circulation will gasify in the cooler bin 3 is taken away, coolant is being back to the hot junction by self gravitation after the cold junction of gravity assisted heat pipe 2 carries out condensation, and then circulation, gravity assisted heat pipe 2 inwalls are provided with long straight connected in star 21, the cross section of this groove 21 is trapezoidal, this groove helps the heat exchange between coolant and the gravity assisted heat pipe 2, gravity assisted heat pipe 2 is better dispelled the heat, help also that coolant refluxes in order after the cold junction condensation of gravity assisted heat pipe 2, do not influence the coolant of gasification, do not influence radiating effect.
Steaming pipe in the above execution mode is a gravity assisted heat pipe, it includes but not limited to this gravity assisted heat pipe, as long as can reach the steaming Guan Junneng application that the technical program requires, vacuum tube as annular, steam the pipe inner groovy and can be long straight shape, also can be the groove of spirality, shape such as curved, the cross section of groove also can make other shapes, as long as help heat exchange, help the backflow of coolant, do not influence the gasification coolant, the cross sectional shape that do not influence radiating effect evenly uses.
