Abstract

The utility model discloses a heat sink which aims to overcome the defect that the existing heat sink has bad heat dissipation effect. The heat sink comprises a fin group array consisting of a plurality of groups of fins; fin groups are mutually longitudinally parallelly arranged; each fin group comprises a plurality of heat dissipation fins transversely and parallelly arranged; each heat dissipation fin in each fin group is fixed by a heat pipe in an insertion way; a base plate is arranged at one end parallel to each heat dissipation fin of each fin group; and the heat pipe is inserted and fixed with the base plate. An LED (light-emitting diode) lamp chip is attached onto the base plate of the heat sink; the heat emitted by the LED is conducted to the heat pipe through the base plate and then is conducted to the heat dissipation fins through the heat pipe; as each heat dissipation fin is made into a Z-shaped structure, the heat dissipation fin is not limited by the direction in use and can be used at any angle, so that the heat dissipation area is increased by 20 percent on an equal plane; and as the convection action of a gap between each two heat dissipation fins is strong, the heat is convenient to discharge.

Description

Radiator

Technical field

The utility model relates to a kind of radiator, particularly a kind of fin slices radiator that is used for the heat radiation of LED lamp.

Background technology

The fin slices radiator of existing LED lamp, its shape all are smooth, and service orientation all is level or vertical direction, and horizontal direction is used influences radiating effect, and vertical direction is used influences aesthetic appearance.

The utility model content

The purpose of this utility model is to disclose a kind of radiator, to overcome the defective of existing radiator heat-dissipation poor effect.

Radiator described in the utility model, comprise the fins group array of forming by many groups fins group, the mutual parallel longitudinal setting of fins group, every group of fins group comprises the radiating fin that multi-disc laterally is arranged in parallel, each radiating fin in the fins group is fixed by the heat pipe plug-in mounting, an end parallel with each radiating fin in fins group is provided with substrate, and heat pipe and this substrate plug-in mounting are fixed.

Wherein, the stepped setting of radiating fin, the lateral cross section of radiating fin is the setting of Z font.

Wherein, be connected with the LED lamp at the back side of substrate.

Radiator of the present utility model, LED wick sheet is attached on the substrate of radiator, the heat that LED distributes is passed to heat pipe by substrate, heat pipe conducts heat to radiating fin again because radiating fin makes the Z font structure, during use not the recipient to restriction, can both use arbitrarily angled, on equal plane, make area of dissipation increase 20%, and, make things convenient for the discharge of heat owing to the convection action in slit between the every radiating fin is very strong.

The specific embodiment

Below in conjunction with accompanying drawing, a specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.

As shown in Figure 1-Figure 3, the utility model radiator comprises: the fins group array of being made up of four groups of fins group, fins group is parallel longitudinal setting up and down mutually, every group of fins group comprises multi-disc radiating fin 1, each sheet radiating fin 1 is the setting that laterally is arranged in parallel, each radiating fin 1 in the above-mentioned fins group is fixed by heat pipe 2 plug-in mountings, be provided with substrate 3 at fins group and each radiating fin 1 a parallel end, heat pipe 2 is fixed with these substrate 3 plug-in mountings, be fixed with the LED lamp at the back side of substrate 3, the LED lamp outwards dispels the heat by heat pipe 2 and each radiating fin 1.

Wherein, radiating fin 1 stepped setting, the lateral cross section of radiating fin 1 is the setting of Z font.

Adopt the LED lamp that has Z font radiating fin radiator of the present utility model, light source can not influence heat sinking function to arbitrarily angled projection during use, is applicable to any angle illumination.

More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
