Abstract
The invention discloses a radiator composed of large and small circular arc cooling fin arrays so as to overcome the advantages of small radiation area, poor radiation effect, large volume, high weight and high cost. A plurality of small circular arcs are arranged on one side of each large circular arc, and a plurality of small asymmetric circular arcs are arranged at the other side of each large circular arc, so that small and large circular arc cooling fins are formed; and the small and large circular arc cooling fin arrays form a whole radiator which is in the shape of a hexagon, a circle, a rectangle, a triangle, a polygon or an irregular shape. According to the radiator, not only the radiation area is large and the radiation effect is good, but also materials and the cost are saved. The radiator is widely used for radiation of power devices, particularly for radiation of electronic devices such as an LED (light-emitting diode) and the like.
Description
Technical field
The invention belongs to heat sink technology, especially relate to the radiator of large small arc-shaped fin array composition.
Background technology
Existing passive radiator, particularly the passive heat radiation device of the high-power electronic device such as LED easily produces following point: 1. area of dissipation is little, radiating effect is bad, being because some radiator fin can not obtain maximum radiating surface to greatest extent with limited material, is not the problems such as best radiating mode; 2. to waste too much radiator material, obtain larger area of dissipation, thus make weight, the cost increase of product, volume, installing space are excessive.
Summary of the invention
The drawbacks such as the little radiating effect of existing radiator heat-dissipation area is bad in order to overcome, waste material, cost are high, Heavy Weight, the present invention proposes a kind of orthodrome in conjunction with asymmetric small arc-shaped fin array composition radiator, not only area of dissipation is large, good heat dissipation effect, and reduces material and cost.
The technical solution adopted for the present invention to solve the technical problems is: arrange several small arc-shapeds in the one side of orthodrome sheet base, and the another side of orthodrome sheet base is asymmetric arranges several small arc-shapeds, forms a cell size circular arc fin.Asymmetrical small arc-shaped is set on the two sides of orthodrome sheet base, area of dissipation is increased, and thickness evenly, thermal conductivity and intensity increases, reduces material weight and cost.
The radiator of described large small arc-shaped fin array composition, with a kind of integrated radiator in unit fin array composition hexagon, circle, four limit rectangles, triangle or polygon or irregular form, preferred three-dimensional hexagon.
The radiator of described large small arc-shaped fin array composition, arrange an entity in integrated radiator somewhere, entity periphery and several large small arc-shaped fin are connected to become the grain of heat conduction, heat radiation.
The radiator of described large small arc-shaped fin array composition, install in entity one side the device needing heat radiation, another side arranges large small arc surface or provided with fan, carries out auxiliary heat dissipation.
The radiator of described large small arc-shaped fin array composition, according to the power of heater members, adjusts the array quantity of large small arc-shaped fin, size arc radius, sheet body thickness and height.
The radiator of described large small arc-shaped fin array composition, by cast or forge or extrude or the processes such as punching press integrally after, effects on surface carries out Shot Blasting.
The radiator of described large small arc-shaped fin array composition, lotus leaf effect process is carried out on surface.
The invention has the beneficial effects as follows, orthodrome two sides arranges multiple small arc-shaped, strengthens area of dissipation, and large small arc-shaped fin formation pipeline is cellular, and radiating airflow is unimpeded, good heat dissipation effect, reduces material cost.
