Abstract
A flat tube used on air-conditioning is prepared for setting projected points in the same size on internal wall of flat tube channel, distributing projected points on internal wall of flat tube channel in equal distance along longitudinal direction and setting projected points on top internal wall of flat tube channel to be opposite to each other with projected points on bottom internal wall of flat tube channel.
Description
Technical field:
The present invention relates to a kind of heat exchange elements, particularly a kind of A/C evaporator, condenser flat tube.
Background technology:
Air conditioning for automobiles extensively adopts band-tube evaporator and the used flat tube of condenser, parallel flow evaporators and condenser, and parallel a plurality of square opening coolant channels are arranged in it.The conduit wall of this multi-channel flat pipe is a smooth surface, easily forms laminar flow when cold-producing medium flows in passage, and heat-transfer effect is relatively poor.
Summary of the invention:
The purpose of this invention is to provide a kind of flat tube for air conditioner, the heat-transfer effect of this flat tube is good.Technical scheme of the present invention is that the inwall of flat tube passage is provided with prominent point.Described prominent point be shaped as circle or ellipse.Prominent on the described flat tube vias inner walls vertically equidistantly distributing or do not equidistantly distributing.Prominent point on prominent point on the last inwall of described flat tube passage and the following inwall staggers toward each other or mutually.The equal and opposite in direction of described prominent point or unequal.The present invention is owing to be provided with prominent point on the inwall of flat tube passage, thereby has the good remarkable advantage of heat-transfer effect compared with the prior art.
Description of drawings:
Fig. 1 is the front view of flat tube for air conditioner of the present invention, and Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment:
In conjunction with above accompanying drawing the present invention is elaborated, when flowing, cold-producing medium produces laminar flow in the flat tube passage, the present invention is provided with prominent point 2 on the upper and lower surface of flat tube 1 passage, prominent point vertically equidistantly distributes along flat tube, also can not be equally spaced, and the prominent point on the upper and lower inner surface can be relative one by one, it also can be mutual stagger arrangement, prominent point is circular prominent point, and its size can equate, also can be unequal.Prominent point as shown in Figure 2 is the prominent point 2 of circle equidistant, that distribute relatively up and down.Described prominent point can adopt punching press or roll extrusion to form.Prominent point on the flat tube wall can make cold-producing medium produce flow-disturbing, and helps boiling and condensation heat transfer.
