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 air conditioner, its heat exchanger 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 of equal length or unequal length; each elliptical pipe segment 2 can be of 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 ...

Abstract

The invention discloses an improved heat exchange enhanced air conditioner. The heat exchanger 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 is equal in length; each elliptical pipe section Equal length; the intersection angle of the elliptical major axes of two adjacent elliptical pipe sections is 15°~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 and two arcs Symmetrical and approximately symmetrical flat circles or circles fitted with a shape or multiple arcs; each ellipse transition pipe section is equal in length; the two ends of the heat exchange tube are provided with a circular pipe joint section; the inner wall of the circular pipe joint section is smooth; the circle The inner diameter of the pipe joint section is the same as that 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...
