Embodiment Construction

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

[0013] like figure 1 , figure 2 As shown, an improved 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 Long or unequal length; each oval tube section 2 can be equal or unequal length. 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 symmetrical oblate circle o...

Abstract

The invention discloses an improved heat exchange enhanced radiator which comprises a heat exchange tube. The heat exchange tube comprises round tube sections which are connected with elliptical tube sections through elliptical transitional sections, wherein the round tube sections are equal in length, the elliptical tube sections are equal in length, and the crossing angle of long axes of section ellipses of every two adjacent elliptical tube sections ranges from 15 degrees to 90 degrees. The cross section of each elliptical tube section is shaped like a standard ellipse or an approximate ellipse or an oblate circle formed by two straight lines and two arcs or a symmetric or approximately symmetric oblate circle or circle formed by fitting multiple sections of arcs. The elliptical transitional sections are equal in length. The two ends of the heat exchange tube are provided with round tube joint sections with the smooth inner walls. The internal diameter of the round tube joint sections is the same with the internal diameter of the round tube sections. The improved heat exchange enhanced radiator is simple in structure, the speed field and the temperature gradient field are effectively and reasonably coordinated to be balanced, and the improved heat exchange enhanced radiator saves energy and is environment-friendly and high in 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...
