Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Herein, if do not have specified otherwise, relate to formula, "/" represents division, "×", " * " represent multiplication.
As Fig. 1, shown in 2, the radiating tube that a kind of radiator uses, described radiating tube comprises base tube 1 and is positioned at the fin 3-5 of base tube periphery, as Fig. 1, shown in 2, the cross section of described base tube is isosceles triangle, described fin comprises the first fin 3 and the second fin 4, 5, described first fin 3 is outward extending from isosceles triangle drift angle, described second fin 4, 5 comprise multiple fin 4 of stretching from the facing epitaxy at two waist places of isosceles triangle and from the outward extending multiple fin 5 of the first fin, the second fin 4 extended to same direction, 5 is parallel to each other, such as, as shown in the figure, waist from the isosceles triangle second waist 7(left side) outward extending second fin 4, 5 is parallel to each other, from the isosceles triangle first waist 6(i.e. waist on the right) outward extending second fin 4, 5 is parallel to each other, described first fin 3, second fin 4, 5 ends extended form the second isosceles triangle, as shown in Figure 1, the length of the waist of the second isosceles triangle is S, described base tube 1 inside arranges first fluid passage 2, and described first fin 3 inside arranges second fluid path 10, described first fluid passage 3 and second fluid channel connection 10.Such as, as described in Figure 1, be communicated with at isosceles triangle corner position.
As preferably, first fluid passage is isosceles triangle.
By vibrational power flow so, the multiple fin of base tube 1 outer setting can be made, increase heat radiation, fluid passage is set in the first fin inside simultaneously, make fluid enter in the first fin, the second fin be directly connected with the first fin carries out heat exchange, adds heat-sinking capability.
Described radiator is preferably convector, and the fluid of described first fluid passage and second fluid passage is preferably water.
General radiating tube is all that surrounding or both sides arrange fin, but find in engineering, generally heat convection effect is bad for the fin of the side contacted with wall, because air wall side flow relatively poor, therefore isosceles triangle base 8 is set to plane by the present invention, time therefore fin is installed, can directly by plane and wall close contact, compared with other radiator, installing space can be saved greatly, avoid the waste in space, take special fin form simultaneously, ensure to meet best radiating effect.
As preferably, described second fin 4,5 relative to the face specular at the first fin 3 center line place, namely relative to the face specular at the line place of the summit of isosceles triangle and the mid point at place, base.
As preferably, the second fin extends perpendicular to two waists of the second isosceles triangle.
When the length on the limit of isosceles triangle is certain, first fin 3 and the second fin 4, 5 is longer, then heat transfer effect is better in theory, find in process of the test, when the first fin and the second fin reach certain length time, then heat transfer effect just increases very not obvious, main because along with the first fin and the increase of the second fin length, also more and more lower in the temperature of fin end, along with temperature is reduced to a certain degree, heat transfer effect then can be caused not obvious, also add the cost of material on the contrary and considerably increase the space occupied of radiator, simultaneously, in heat transfer process, if the spacing between the second fin is too little, also the deterioration of heat transfer effect is easily caused, because along with the increase of radiating tube length, in air uphill process, boundary layer is thickening, boundary layer between abutting fins is caused to overlap mutually, worsen heat transfer, spacing between too low or the second fin of radiating tube length causes too greatly heat exchange area to reduce, have impact on the transmission of heat, therefore in the distance of the second adjacent fin, the length of side of isosceles triangle, an optimized size relationship is met between the length of the first fin and the second fin and heat sink length.
Therefore, the present invention is the dimensionally-optimised relation of the radiator of the best summed up by thousands of test datas of the radiator of multiple different size.
The distance of described the second adjacent fin is L1, and the base length of described isosceles triangle is W, and the length of the waist of described second isosceles triangle is S, and the relation of above-mentioned three meets following formula:
