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] The present invention will be further described below in conjunction with the drawings and embodiments:

[0013] Such as figure 1 , figure 2 As shown, a heat exchange enhanced floor heating includes heat source equipment, control equipment, and floor heating pipelines 5. The floor heating pipelines 5 include a circular pipe section 1; the circular pipe section 1 is connected to an elliptical pipe section 2 through an elliptical transition section 3; each circular pipe section 1 can They are of equal length or unequal length; each elliptical pipe section 2 can be of equal length or unequal length. The cross-sectional ellipse major axis A of the two adjacent elliptical pipe sections 2 has an intersecting angle C of 15°-90°, and this angle is used to increase the resistance when the liquid flows in the pipe. The cross-sectional shape of the elliptical transition pipe section 3 is a standard ellipse or an approximately ellipse or an oblate formed by two straight lines and two...

Abstract

The invention discloses a heat exchange enhancement floor heating system which comprises a heat source device, a control device and a floor heating pipeline. The floor heating pipeline comprises round pipe segments; the round pipe segments are connected with oval pipe segments through oval transitional segments; all the round pipe segments are equal in length; all the oval pipe segments are equal in length; the cross angle of long axes of ovals of the sections of every two adjacent oval pipe segments ranges from 15 degrees to 90 degrees; the shape of the cross section of each oval transitional pipe segment is a standard oval or an approximate oval or a flat circle formed by two straight lines and two arcs or a symmetric or nearly symmetric flat circle formed by fitting multiple arcs or a circle; all the oval transitional segments are equal in length; round pipe joint segments are arranged at the two ends of the floor heating pipeline; the inner walls of the round pipe joint segments are smooth; and the inner diameter of the round pipe joint segments is the same as that of the round pipe segments. The heat exchange enhancement floor heating system is simple in structure, the balance of a speed field and a temperature gradient field is effectively and reasonably coordinated, and energy conservation and environment protection 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] The heat transfer enhancement technology has been widely used in daily life because it can increase the heat transfer rate and achieve the purpose of energy saving. Heat transfer enhancement technology is mainly divided into active enhancement and passive enhancement technology. The former refers to heat transfer enhancement technologies that require energy input from the outside, such as electric field enhancement, magnetic field enhancement, vibration enhancement technology, etc.; the latter refers to heat transfer enhancement technologies that do not require external energy, so it is easier to be applied to engineering. Passive enhancement techniques usually include expanded surfaces (fins), tube inserts, swirl (turbulent flow) generators, and so on. Passive enhancement technology has been widely used, but there is still a c...
