Abstract
The utility model discloses a hot extrusion multihole heat exchange aluminum pipe, relates to a heat exchange element, and particularly relates to an aluminum pipe for vehicle-mounted air-conditioner evaporators and condensers. The hot extrusion multihole heat exchange aluminum pipe comprises a rectangular channel (1), uniform projections (2) are arranged on upper, lower, left and right inner walls of the channel (1) and are tooth-shaped, and tops of the tooth-shaped projections (2) are circular-arc-shaped (3). The hot extrusion multihole heat exchange aluminum pipe has an expanded heat conduction surface, is fine in heat dissipation property and high in pressure resistant strength, and is durable.
Description
Technical field
The utility model relates to a kind of heat exchange elements, especially a kind of on-board air conditioner aluminum pipe for evaporator.
Background technology
Air conditioning for automobiles extensively adopts band-tube evaporator, and the flat tube that parallel flow evaporators is used has parallel a plurality of square or rectangular opening coolant channel 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.Flat tube all has the passage that makes cold-producing medium disperse and flow, and the cross section that this passage has is a rectangle, and the place very easily produces eddy current at four right angles, heat exchanging is unfavorable, the channel cross-section that has is for circular or oval, and such passage is few in flat tube, has restricted the exchange capability of heat of further raising heat exchanger.
The utility model content
Problem to be solved in the utility model is to overcome the problem that above technology exists, and provides a kind of heat-transfer effect good, can avoid producing the hot extrusion porous heat transfer aluminum pipe of eddy current.
Hot extrusion porous heat transfer aluminum pipe comprises passage, and described passage is a rectangle, all is provided with uniform salient point up and down on the inwall, the described salient point of passage be shaped as profile of tooth, the top of dentation salient point is a circular arc.
Salient point is a dentation, can make the area in the passage be maximum, and the uniform dentation salient point that is provided with in each passage, makes that the area in each passage all increases identical quantity, and the area of increase is all the same in each passage like this.Area is promoted to greatest extent, more helps the raising of heat-transfer effect.
The salient point that described passage is provided with on last inwall and following inwall toward each other.
The salient point that described passage is provided with on left inwall and right inwall toward each other.
The beneficial effects of the utility model are: thermal conductive surface enlarges, and thermal diffusivity is good; The compression strength height; Durable.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Fig. 2 is the dentation salient point of the utility model vias inner walls.
Wherein, 1-passage; The 2-salient point; 3-salient point top is a circular arc.
The specific embodiment
With length is 100 mm, thickness is 5.5 mm, the flat heat exchange pipe that middle reinforcement thickness is 0.6 mm is an example, as depicted in figs. 1 and 2, a kind of hot extrusion porous heat transfer flat tube, passage 1 is a rectangle, all is provided with uniform salient point 2 up and down on the inwall, salient point 2 be shaped as profile of tooth, salient point 2 tops are circular arc 3.
With length is 85 mm, thickness is 5 mm, the flat heat exchange pipe that middle reinforcement thickness is 0.7 mm is an example, as depicted in figs. 1 and 2, a kind of hot extrusion porous heat transfer flat tube, passage 1 is a rectangle, all is provided with uniform salient point 2 up and down on the inwall, salient point 2 be shaped as profile of tooth, salient point 2 tops are circular arc 3.The salient point 2 that passage is provided with on last inwall and following inwall toward each other.The salient point 2 that passage is provided with on left inwall and right inwall toward each other.
Claims (3)
1. hot extrusion porous heat transfer aluminum pipe, comprise passage, it is characterized in that: described passage (1) is a rectangle, all is provided with uniform salient point (2) on the inwall up and down of passage (1) lining, described salient point (2) be shaped as profile of tooth, the top of dentation salient point (2) is circular arc (3).
2. hot extrusion porous heat transfer aluminum pipe according to claim 1 is characterized in that: the salient point (2) that described passage is provided with on last inwall and following inwall toward each other.
