Specific embodiment

Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.

The present embodiment provides a kind of height wing radiators, as shown in Figs. 1-5, including substrate 1 and at least two groups radiating fin 2, at least two groups radiating fin 2 is respectively positioned on the same side of substrate 1 and one end and substrate 1 connect, and radiating fin 2 hangs down with substrate 1 Straight setting, convenient for heat dissipation.The height of each one end of radiating fin 2 far from substrate 1 is identical in same group of radiating fin 2, arbitrarily The height of 1 one end of separate substrate of two different group radiating fins 2 is different, and all radiating fins 2 are on substrate 1 according to equidirectional It is intervally arranged.In the present embodiment, the length direction of radiating fin 2 and the length direction of substrate 1 are equidirectional, width direction and substrate 1 width direction is equidirectional, and certainly, radiating fin 2 can also be arranged along other directions, such as the width direction of radiating fin 2 Diagonal along substrate 1 or the length direction etc. along substrate 1.Specifically, being equipped in the present embodiment two groups different high The radiating fin 2 of degree, respectively the first height radiating fin 2 and the second height radiating fin 2, wherein the first height is greater than second Highly.

The thickness of substrate 1 can be uniformly, be also possible to non-uniform, and the thickness of substrate 1 is uneven in the present embodiment Even, first thickness H1 and second thickness H2 is included at least, and the numerical value of first thickness H1 is greater than the numerical value of second thickness H2. Specifically, substrate 1 is second thickness H2 in two sides in the width direction, it is first thickness in part intermediate in the width direction H1.By keeping the part among substrate 1 thicker, the part of two sides is relatively thin, and the Temperature Distribution for facilitating the height wing radiator is equal It is even, keep the heat dissipation effect of height wing radiator everywhere consistent.It should be noted that substrate 1 is not provided with the side of radiating fin 2 For plane, it can need to radiate with other in order to substrate 1 or the component of cold scattering connects.For example, can be flat by the side of substrate 1 Face be connected to heat source perhaps the surface of cold source and between the side plane of substrate 1 and cold source or heat source be added thermal conductivity it is good Silicone grease enhances its heat transfer effect.

In the present embodiment, height of the two adjacent radiating fins 2 far from 1 one end of substrate is different, and two neighboring scattered Spacing between hot fin 2 is equal, the air stream at substrate 1 can be made to reduce to the path of external diffusion, so that thermal expansion It dissipates rate to increase, for the air stream at substrate 1 to the path of external diffusion as shown in two arrows in Fig. 2, respectively first is high Spend the diffusion path of the air stream at radiating fin 2 and the corresponding close substrate 1 of the second height radiating fin 2.

As shown in figure 3, at least one groove 21 or protrusion are equipped in the present embodiment on radiating fin 2, specifically, this Multiple grooves 21 are equipped on the surface of 2 width direction two sides of radiating fin in embodiment, and multiple grooves 21 are connected with each other, It is whole that wavy shape is presented.Certainly, it can also be respectively provided on the surface of 2 width direction two sides of radiating fin in the present embodiment more A protrusion, and multiple protrusions is made to be connected with each other, it is whole that wavy shape is presented.It is of course also possible to by groove 21 or protrusion Other shapes being readily apparent that are shaped to, but this programme is preferably waveform, because wavy shape is easier Laminar flow layer is destroyed, to improve the coefficient of heat transfer of height wing radiator, improves heat exchange efficiency, and by radiating fin 2 Surface setting protrusion or groove 21, can increase the surface area of radiating fin 2, so as to expand dissipating for height wing radiator Heat area increases heat dissipation capacity.

In the present embodiment, radiating fin 2 and substrate 1 are an integral structure, and material is preferably aluminium, are had good thermally conductive Performance, and affordable, the occasion that can be used to freeze and heat simultaneously.

Obviously, the above embodiments of the present invention is used for the purpose of clearly illustrating examples for clearly illustrating the present invention, and It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments Exhaustion.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc., should be included in Within the protection scope of the utility model claims.
