Herein, without specified otherwise, relating to formula, "/" represents that division, "×", " * " represent multiplication.
nullSuch as Fig. 1、Shown in 2，The radiating tube that a kind of radiator uses，Described radiating tube includes base tube 1 and is positioned at the fin 3-5 that base tube is peripheral，Such as Fig. 1、Shown in 2，The cross section of described base tube is isosceles triangle，Described fin includes 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 include multiple fin 4 extended outwardly from the two of isosceles triangle waist places and from the first outward extending multiple fin 5 of fin，The second fin 4 extended to same direction、5 is parallel to each other,Such as，As shown in the figure，Waist from isosceles triangle the second waist 7(left side) outward extending second fin 4、5 is parallel to each other，From isosceles triangle the 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 a length of S of the waist of the second isosceles triangle；The internal first fluid passage 2 that arranges of described base tube 1, described first fin 3 is internal arranges second fluid passage 10, described first fluid passage 3 and second fluid channel connection 10.Such as, as described in Figure 1, connect at isosceles triangle corner position.
As preferably, first fluid passage is isosceles triangle.
Arranged by structure so, so that base tube 1 is outside arranges multiple fin, increase heat radiation, fluid passage is set inside the first fin simultaneously, making fluid enter in the first fin, the second fin being 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 surrounding or both sides arrange fin, but find in engineering, the fin of the side contacted with wall generally heat convection effect is bad, because air wall side flow relatively poor, therefore isosceles triangle base 8 is set to plane by the present invention, therefore the when of fin being installed, directly plane can be in close contact with wall, compared with other radiator, can greatly save installing space, avoid the waste in space, take special fin form, it is ensured that meet optimal radiating effect simultaneously.
