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 water heater, its heat source device includes a heat exchange pipe 5, 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 length or unequal length; each elliptical pipe segment 2 can be equal length 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 app...

Abstract

The invention discloses a water heater with enhanced heat exchange. The heat source device includes a heat exchange tube, and the heat exchange tube includes a circular pipe section; the circular pipe section is connected to the elliptical pipe section through an elliptical transition section; each circular pipe section has the same length; each elliptical pipe section has the same length ; The cross-sectional angle of the major axes of two adjacent elliptical pipe sections is 15° to 90°; the cross-sectional shape of the elliptical transition pipe section is a standard ellipse or an approximate ellipse or an oblate circle formed by two straight lines plus two arcs or Symmetrical and approximately symmetrical flat circles or circles fitted by multi-section arcs; each ellipse 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 joints The inner diameter of the segment is the same as that of the circular tube segment. 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...
