Description

Aluminum radiator

Technical Field

The utility model belongs to the technical field of the heat dissipation, especially, relate to an aluminium system radiator.

Background

The radiator is a device for radiating heat of parts which are easy to heat in mechanical equipment or high-power electrical appliances, and is mostly made of materials such as aluminum alloy, brass or bronze and the like. The existing aluminum radiators have different shapes, and adopt a radiating mode of enlarging the radiating area to obtain higher-efficiency radiating, but the existing method is only to add plate-type radiating fins on the radiator main body to conduct the heat of the electronic product to the external environment, but the radiating fins of the design are arranged in parallel towards one direction and can only exchange heat with air in one direction, so that the heat exchange efficiency is low, and the radiating effect is poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an aluminium system radiator, the heat radiation fin who has solved current radiator is unfavorable for the circulation of air towards a direction parallel arrangement, and heat exchange efficiency is low, the poor problem of radiating effect.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model relates to an aluminium system radiator, which comprises a substrate, a base plate fixed surface has the fin, fin vertically and horizontally staggered forms rectangle palace check structure, fin surface equidistance interval is equipped with the breach and makes the little lower extreme in fin upper end big.

Furthermore, the gap is in an inverted triangle shape and is arranged between the intersection points of the cooling fins and the grids.

The utility model discloses following beneficial effect has:

1. the utility model discloses do benefit to the circulation of air more, it is higher with the heat exchange efficiency of air, when not reducing fin heat radiating area, can have higher radiating efficiency.

2. The utility model discloses accessible aluminum alloy integrated into one piece, the production degree of difficulty is little, low in production cost.

Of course, it is not necessary for any particular product to achieve all of the above-described advantages at the same time.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic perspective view of an aluminum heat sink of the present invention;

fig. 2 is a top view of the structure of the present invention;

fig. 3 is a side view of the structure of the present invention.

In the drawings, the components represented by the respective reference numerals are listed below:

1-substrate, 2-heat sink, 3-gap.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention relates to an aluminum heat sink, which comprises a substrate 1, wherein fins 2 are fixed on a surface of the substrate 1, the fins 2 are criss-cross arranged to form a rectangular grid structure, notches 3 are arranged on surfaces of the fins 2 at equal intervals to make upper ends of the fins 2 smaller and lower ends larger, the substrate 1, the fins 2 and the notches 3 can be formed by aluminum alloy, and the aluminum heat sink has low production difficulty and low cost.

Wherein, breach 3 is the triangle-shaped of falling, and locate between 2 palace check crosspoints of fin, interconnect between 2 bottommost ends of fin, do not reduce the heat conduction area with 1 contact of base plate, because fin 2 is vertically and horizontally staggered and sets up, before not having breach 3, it is bigger than the structure heat radiating area towards a direction parallel arrangement, but be unfavorable for the heat dissipation, when having 3 structures of breach, the breach part is equivalent to by the 2 remaining areas of fin of crisscross setting with it supplementations, and because each angle all has breach 3, do benefit to the circulation of air more, it is higher with the heat exchange efficiency of air, therefore the utility model discloses when not reducing heat radiating area, can have higher radiating efficiency.

In the description herein, references to the description of "one embodiment," "an example," "a specific example," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
