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, an improved heat exchange enhanced water heater, its heat source device 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 Is equal or unequal length; each elliptical pipe 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 ...

Abstract

The invention discloses an improved heat exchange enhanced water heater. A heat source device of the improved heat exchange enhanced water heater comprises a heat exchange pipe. The heat exchange pipe comprises round pipe sections. The round pipe sections are connected with oval pipe sections through oval transition sections. The round pipe sections are equal in length. The oval pipe sections are equal in length. The cross angle of section oval long axes of the two adjacent oval pipe sections is 15-90 degrees. The cross sections of the oval transition pipe sections are in the shape of a standard oval or the shape similar to the oval or the shape of a flat round formed by two straight lines and two circular arcs or the shape of the symmetric and similarly-symmetric flat round or circle formed through fitting of multiple sections of arcs. The oval transition pipe sections are equal in length. The two ends of the heat exchange pipe are provided with round pipe connector sections. The inner walls of the round pipe connector sections are smooth. The round pipe connector sections and the round pipe sections are equal in inner diameter. The improved heat exchange enhanced water heater is simple in structure, the balance of a speed field and a temperature gradient field is effectively and reasonably coordinated, energy saving and environment friendliness are achieved, and 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...
