CN204756844U - A heat radiation fins for street lamp - Google Patents

Abstract

The utility model discloses a heat radiation fins for street lamp, including the base with set up a plurality of fin bodies on the base, the thickness of every fin body be 0.1 -0.3mm, interval between the two adjacent fin bodies be 0.5mm, the surface of every the fin body graphite heat dissipation layer that has all coated, the thickness that graphite dispels the heat layer is 0.02 -0.04mm. Through the thickness size attenuation with the fin body to make its adjacent clearance grow between two, make its holistic heat dissipation space bigger, guarantee its radiating efficiency, on every fin body surface coating graphite heat dissipation layer, high heat conduction radiation performance through graphite heat dissipation layer improves its holistic heat dispersion, and the more ideal heat dissipation of having satisfied the LED street lamp has brought very big convenience for the enterprise.

Description

For the radiating fin of street lamp

Technical field

The utility model relates to heat abstractor application, particularly a kind of radiating fin for street lamp.

Background technology

At present, LED progressively substitutes traditional fluorescent tube because of advantages such as its long service life, more energy-conserving and environment-protective, street lamp industry lamp also more and more uses LED, but LED street lamp due to its heat dissipation capacity larger, it is higher to the requirement of heat radiation, now widely used radiating fin can not meet the cooling requirements of LED street lamp completely, brings very large inconvenience to enterprise.

Utility model content

For solving Problems existing in above-mentioned background technology, the purpose of this utility model is the radiating fin being provided for street lamp, to reach the heat-sinking capability improving radiating fin, the object more preferably meeting the heat radiation of LED street lamp.

For achieving the above object, the technical solution of the utility model is as follows:

For the radiating fin of street lamp, comprise base and be arranged on the multiple fin bodies on described base, the thickness of each described fin body is 0.1-0.3mm, spacing between adjacent two fin bodies is 0.5mm, the surface of each described fin body is coated with a graphite radiating layer, and the thickness of described graphite radiating layer is 0.02-0.04mm.

Preferably, described base is provided with multiple thermal vias.

By technique scheme, the radiating fin for street lamp that the utility model provides, by by thinning for the gauge of fin body, and makes the gap between its adjacent two panels become large, makes the heat-dissipating space of its entirety larger, ensure its efficiency of dispelling the heat; Apply a graphite radiating layer at each fin body surface, improved the heat dispersion of its entirety by the high heat conduction and heat radiation performance of graphite radiating layer, more preferably meet the heat radiation of LED street lamp, bring very large convenience to enterprise.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.

Fig. 1 is the structural representation of the radiating fin for street lamp disclosed in the utility model embodiment.

In figure, number designation represents the title of parts:

1, base 2, fin body 3, thermal vias

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

The radiating fin for street lamp that the utility model provides, as shown in Figure 1, the multiple fin bodies 2 comprising base 1 and be arranged on base 1, base 1 is provided with multiple thermal vias 3, conveniently better dispel the heat, the thickness of each fin body 2 is 0.1-0.3mm, spacing between adjacent two fin bodies 2 is 0.5mm, the surface of each fin body is coated with a graphite radiating layer, and the thickness of graphite radiating layer is 0.02-0.04mm, and the graphite of graphite radiating layer is optional uses artificial synthetic graphite.

The disclosed radiating fin for street lamp of the utility model, by by thinning for the gauge of fin body, and makes the gap between its adjacent two panels become large, makes the heat-dissipating space of its entirety larger, ensure its efficiency of dispelling the heat; Apply a graphite radiating layer at each fin body surface, improved the heat dispersion of its entirety by the high heat conduction and heat radiation performance of graphite radiating layer, more preferably meet the heat radiation of LED street lamp, bring very large convenience to enterprise.

To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
