Example Embodiment

[0012] The present invention will be further described below in conjunction with the drawings and embodiments:

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

Abstract

The invention discloses an improved 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 has the same length; each elliptical tube section has the same 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 transitional pipe section is a standard ellipse or an approximate ellipse or an oblate circle or multiple sections formed by two straight lines plus two arcs Symmetrical and approximately symmetrical flat circles or circles fitted by arcs; each elliptical transition pipe section is equal in length; the two ends of the heat exchange tube are provided with circular pipe joint sections; the inner wall of the circular pipe joint section is smooth; the circular pipe joint section It is the same as the inner diameter of the circular pipe section. 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...
