Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0013] Such as figure 1 , figure 2 As shown, a heat exchange enhanced radiator includes a heat exchange pipe 5, and the heat exchange pipe 5 includes a circular pipe section 1; the circular pipe section 1 is connected to the elliptical pipe section 2 through an elliptical transition section 3; each circular pipe section 1 can be equal in length or unequal lengths; each elliptical pipe segment 2 can be equal lengths or unequal lengths. The cross-section angle C of the major axis A of the ellipse of two adjacent elliptical pipe sections 2 is 15°-90°, and this angle is to increase the resistance generated when the liquid in the pipe flows. The cross-sectional shape of the elliptical transition pipe section 3 is a standard ellipse or an approximate ellipse or an oblate circle formed by two straight lines plus two arcs or a symmetrical and approximately symmetr...

Abstract

The invention discloses a heat exchange enhanced radiator, which comprises a heat exchange tube, and the heat exchange tube includes a circular tube section; the circular tube section is connected to an elliptical tube section through an elliptical transition section; each circular tube section is of equal length; each elliptical tube section is of equal length; The intersecting angle of the elliptical major axes of two adjacent elliptical pipe sections is 15°~90°; the cross-sectional shape of the elliptical transition pipe section is a standard ellipse or an approximate ellipse or an oblate circle or multiple arcs formed by two straight lines plus two arcs. Symmetrical and approximately symmetrical flat circles or circles fitted by lines; each ellipse transition pipe section is equal in length; the two ends of the heat exchange tube are provided with a circular pipe joint section; the inner wall of the circular pipe joint section is smooth; the circular pipe joint section and The inner diameters of the circular pipe sections are the same. The invention has a simple structure, effectively and reasonably coordinates the balance of the velocity field and the temperature gradient field, and has high energy saving and environmental protection efficiency.

Description

technical field [0001] The invention relates to a heat transfer device, in particular to a pipe-type heat exchange device. Background technique [0002] Heat transfer enhancement technology has been widely used in daily life because it can increase the heat transfer rate and achieve the purpose of saving energy. Heat transfer enhancement technology is mainly divided into active enhancement technology and passive enhancement technology. The former refers to the heat transfer enhancement technology that requires energy input from the outside, such as electric field enhancement, magnetic field enhancement, vibration enhancement technology, etc.; the latter refers to the heat transfer enhancement technology that does not require external energy, so it is easier to be applied to engineering. Passive enhancement techniques typically include extended surfaces (fins), in-tube inserts, swirl (turbulence) generators, etc. Passive enhancement technology has been widely used, but ther...
