It doubles.The output power of solar cell module is caused to decline, meanwhile, high temperature also seriously affects the reliable of diode PN junction
Property.
Currently, the design of conventional terminal blocks is dissipating the circuit connection of terminal box, bypass diode protection and diode
Heat concentrates in the closed box that one has waterproof requirement so that this pair of of conflicting requirements of heat dissipation and waterproof cannot obtain well
Balance.Both diode radiating is influenced, the reliability of diode is reduced, needs rated current bigger and the lower diodes of Vf,
Increase the cost of diode.Simultaneously because in terminal box temperature raising, cause the reverse leakage current of diode to increase, influence
The output power of component declines.
Therefore, the heat-sinking capability for how improving terminal box, keeps the output power of component, and ensure terminal box diode can
By property, conventional photovoltaic junction box radiator structure is all to realize three major functions of terminal box in an area of space,
And attempt to reduce the temperature of diode by improving the heat-exchange capacity in terminal box.But due to heat conductive silica gel and plastic shell
Thermal coefficient it is too small so that the heat generated when diode operation cannot conduct in time, and the operating temperature of diode is non-
Chang Gao has seriously affected the output power of photovoltaic module and reliability is used for a long time.
