The device is simple in structure; a great amount of heat generated when the diodes work can be directly conducted out of the box body, so that the safe and reliable work of solar photovoltaic array lightning-proof combiner box system equipment is ensured; the device also has the characteristics of convenience in use, mounting and maintenance, low cost and the like.
Description
Technical field
The present invention relates to solar photovoltaic technology field, relate to header box, be 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 during 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 guarantee 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 guaranteed 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 object of the invention is to, overcome the shortcoming and defect of above-mentioned prior art, 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 invention provides a kind of diode heat radiating device of photovoltaic array lightning-proof header box, 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 present invention 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, guarantees photovoltaic array lightning-protection header box system equipment safety, reliably working.
Although structure of the present invention is simple, also very convenient aspect using, installing, safeguard, maintenance cost significantly reduces feature compared with prior art cost.

Embodiment
Below in conjunction with accompanying drawing, further illustrate embodiments of the invention.
As shown in Fig. 1 a～1b, Fig. 4, be the HL-16F type header box embodiment of the diode heat radiating device of a kind of photovoltaic array lightning-proof header box of the present invention, comprise diode 1, radiator 2, casing 3, hold-down screw 4, hold-down screw 5;
Wherein, described radiator 2 is placed in described casing 3 outsides, and the fin of described radiator exposes as shown in Figure 2 and Figure 3;
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, to there being the complete machine of class of safety protection IP special requirement, can be between described radiator 2 and the assembly connection contact-making surface of described casing 3, add electric insulating sealant or electro-insulating rubber bar, to improve class of safety protection IP, and then described diode 1 is assemblied on described radiator 2 by described hold-down screw 5.
Further, for increasing contact area and improving thermal conduction rate, between diode 1 and the assembly connection contact-making surface of radiator 2, smear heat-conducting silicone grease glue material.
The diode heat radiating device of a kind of photovoltaic array lightning-proof header box of the present invention, through experiment test, technique effect is very remarkable:
1, the class of safety protection of assurance device meets higher requirement (for example can meet IP65 requires).
2, the fin of radiator 2 exposes, and can guarantee that diode 1 work produces a large amount of heat energy, can directly derive rapidly outside casing 3, and radiating efficiency significantly improves.
3, between radiator 2 and the contact-making surface of casing 3, add the measures such as electric insulating sealant or electro-insulating rubber bar, guarantee safe and reliable.
4, between diode 1 and the contact-making surface of radiator 2, smear the materials such as heat-conducting silicone grease glue improved connecing heat radiation touch area, improve radiating efficiency.
Of the present invention simple in structure, safe and reliable, use, installation, easy to maintenance, time saving and energy saving, with low cost.The present invention can be widely used in the installation of similar device.
Except above-mentioned example, the present invention can also have other implementation methods.All employings are equal to or the technical scheme of equivalent transformation form, all drop on the protection range of requirement of the present invention.
