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 circular arc, described fin comprises the first fin 3 and the second fin 4, 5, described first fin 3 is outward extending from the mid point of the circular arc of circular arc, described second fin 4, 5 comprise multiple fin 4 of stretching from the facing epitaxy at the arc place of circular arc 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, limit from the circular arc Second Edge 7(left side) outward extending second fin 4, 5 is parallel to each other, from the isosceles triangle first limit 6(i.e. limit 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 isosceles triangle, as shown in Figure 1, the length of the waist of 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 in the position of the mid point of circular arc.
Preferably, first fluid passage is circular arc.
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, the fin one of the side contacted with wall is bad for heat convection effect in situation, because air wall side flow relatively poor, therefore circular arc 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.
