Description
Technical field:
The present invention relates to semiconductor components and devices, be specifically related to the special counnter attack diode (led) module of a kind of photovoltaic combiner box.
Background technology:
In solar photovoltaic generation system, in order to reduce the line between solar-energy photo-voltaic cell array and inverter, use photovoltaic combiner box.Diode (led) module is the important component part of header box, generally selects the essential condition of counnter attack diode (led) module, and pressure drop is low, thermal resistance is little, thermal cycle ability is strong.Pressure drop is lower, and the power consumption of module is less, and the heat that distributes is corresponding also to be reduced, and the temperature rise nature of header box is just little, and thermal resistance is less, and module base plate is less to the temperature difference of chip, and module work is more reliable.Times of thermal cycle is more, and module is more stable, longer service life.General-purpose diode module, on-state voltage drop can only reach 0.90-0.95V, and maximum thermal resistance is tied to module base plate and is reached 1.30, and cold cycling number of times only has 2000 times, even lower, and this can not meet the service condition of photovoltaic combiner box.
Summary of the invention:
Technical problem to be solved by this invention is to overcome existing technological deficiency, provides a kind of photovoltaic combiner box special counnter attack diode (led) module, has the advantages that pressure drop is low, thermal resistance is little, thermal cycle ability is strong, effectively solves the shortcoming of prior art.
Technical problem to be solved by this invention adopts following technical scheme to realize:
The special counnter attack diode (led) module of a kind of photovoltaic combiner box, comprise the first electrode, the second electrode, shell and radiating area, described the first electrode and the second electrode are arranged on the two ends of shell, and described radiating area is arranged between enclosure the first electrode and the second electrode, it is characterized in that:
Described radiating area at least arranges 2, comprises fin, and described fin inside has louvre.
The on-state voltage drop of described counnter attack diode (led) module is 0.76-0.80V, and pressure drop is lower, and the power consumption of module is less, and the heat that distributes is corresponding also to be reduced, and the temperature rise nature of header box is just little.
The maximum thermal resistance of described counnter attack diode (led) module is tied to module base plate and is reached 0.5, and thermal resistance is less, and module base plate is less to the temperature difference of chip, and module work is more reliable.
It is more that the times of thermal cycle of described counnter attack diode (led) module reaches more than 10,000 times times of thermal cycle, and module is more stable, longer service life.
Beneficial effect of the present invention is, provide a kind of photovoltaic combiner box special counnter attack diode (led) module, have the advantages that pressure drop is low, thermal resistance is little, thermal cycle ability is strong, effectively solve the shortcoming that prior art pressure drop is high, thermal resistance large, thermal cycle ability is weak, operating efficiency and the useful life of having improved photovoltaic combiner box.
Brief description of the drawings:
Fig. 1 is structural representation of the present invention.
