Description
Technical field
The utility model relates to solar photovoltaic technology field, relates to header box, is specifically related to a kind of diode heat radiating device of photovoltaic array lightning-proof header box.
Background technology
In photovoltaic array lightning-protection header box, diode power consumption will be far away higher than other components and parts, especially when multi-channel parallel, when multiple diodes are worked simultaneously, often produce a large amount of heats, the temperature rise in header box is obvious, can affect the normal work of photovoltaic apparatus system.Therefore adopt which kind of radiating mode that the temperature rise of diode is controlled in the desired scope of device work and just seems and be even more important, urgent.
In real work, people can, according to the difference of the electric characteristic and application occasion of diode, adopt and have different installation forms and corresponding radiating mode.Conventionally there are following two kinds of ways:
1, the radiator that diode is housed is placed in to box house.Although the method can ensure the class of safety protection (IP) of complete machine, exists diode operation and produces a large amount of heat energy, cannot directly be disseminated to the defect outside casing, also exist the interior temperature rise of casing serious, affect the problem of the normal work of header box.
2, the radiator that heating diode is housed is placed in other independent casing.This has ensured radiating effect to a certain extent, but it is high to exist material cost, the problem of later maintenance inconvenience, and this many body structures define the scope of application of product to a great extent.
The purpose of this utility model is, overcomes the shortcoming and defect of above-mentioned prior art, and design is a kind of simple in structure, and radiating effect is remarkable, safe and reliable; Use, I&M convenience, time saving and energy saving, with low cost, practical diode heat radiating device.
Summary of the invention
In order to overcome above-mentioned shortcoming and defect of the prior art, the utility model provides a kind of diode heat radiating device of photovoltaic array lightning-proof header box, and technical scheme is specially:
A kind of diode heat radiating device of photovoltaic array lightning-proof header box, comprise diode (1), radiator (2), casing (3), hold-down screw (4), hold-down screw (5), it is characterized in that, described radiator (2) is placed in described casing (3) outside, and described radiator (2) is connected by described hold-down screw (4) with described casing (3); Described diode (1) is connected by described hold-down screw (5) with described radiator (2);
Further, between described radiator (2) and the installation contact-making surface of described casing (3), add electric insulating sealant or electro-insulating rubber bar;
Further, between diode (1) and the contact-making surface of radiator (2), smear heat-conducting silicone grease glue material.
The utility model is placed in radiator the casing outside of described header box, heat radiator fin is exposed on the external outward in space, and smear heat-conducting silicone grease glue material between diode and the contact-making surface of radiator, can make diode operation produce a large amount of heat energy derives rapidly outside casing, ensures photovoltaic array lightning-protection header box system equipment safety, reliably working.
Although the utility model structure is simple, also very convenient aspect using, installing, safeguard, maintenance cost significantly reduces feature compared with prior art cost.
