Problems solved by technology

Passive enhancement technology has been widely used, but there is still a common problem, that is, while the heat transfer is enhanced, the flow resistance increases more, which is not conducive to energy saving, thus hindering the wider application of these technologies in various engineering fields

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 reinforcement radiator which comprises a heat exchange pipe. The heat exchange pipe comprises round pipe segments. The round pipe segments are connected with oval pipe segments through oval transition segments. All the round pipe segments are equal in length. All the oval pipe segments are equal in length. The cross angle of section oval long axes of every two adjacent oval pipe segments ranges from 15 degrees to 90 degrees. The cross section of the oval transition pipe segments is in the shape of a standard oval or the shape similar to an oval or the shape of a flat round formed by two straight lines and two arcs or the shape of a symmetric and approximately symmetric flat round or round formed by fitting a plurality of segments of arc lines. All the oval transition pipe segments are equal in length. Round pipe connector segments are arranged at the two ends of the heat exchange pipe. The inner walls of the round pipe connector segments are smooth. The inner diameter of the round pipe connector segments is equal to that of the round pipe segments. The heat exchange reinforcement radiator is simple in structure, balance of a speed field and a temperature gradient field is effectively and reasonably coordinated, and the energy saving and environment protecting efficiency is high.

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...
