Abstract
The utility model discloses a rectangle heat dissipation flat pipe. The cross section of the rectangle heat dissipation flat pipe is a rectangle shape, arc chamfers are arranged on four corners of the rectangle shape, and the thickness of the arc chamfers is greater than that of the sides of the rectangle shape. The rectangle heat dissipation flat pipe is adopted, the arc chamfers are arranged on four edges, the arc chamfers conform to a fluid mechanic principle, so that impurity accumulation is reduced, heat dissipation efficiency for the heat dissipation flat pipe is not affected, and the arc chamfers reduce stress concentration and avoid micro-cracks which are produced at closed angles. The thickness of the arc chamfers is greater than that of the sides of the rectangle shape so as to enhance intensity and further avoid producing cracks.
Description
Technical field
The utility model relates to a kind of car radiation flat tube, relates in particular to a kind of rectangle heat radiating flat tube.
Background technology
Radiator belongs to automobile cooling system, and the radiator in the engine water-cooling system for water is made of three parts such as intake chamber, water-supplying chamber, main leaf and radiator cores.Cooling fluid flows in radiator core, and air passes through outside radiator core.The cooling fluid of heat is owing to turning cold to the air heat radiation, and cold air then heats up because of the heat that the absorption cooling fluid sheds, so radiator is a heat exchanger.Automobile radiators mainly has two kinds: aluminium matter and copper, and the former is used for general passenger car, and the latter is used for Heavy Duty Commercial Car.Heat radiating flat tube is the important composition parts of radiator.
The automobile rectangle heat radiating flat tube of prior art has in use easily lowered its radiating efficiency in the sharp corner accumulated impurity thing impact of rectangle inwall, and easily produces micro-crack at sharp corner and cause heat eliminating medium to leak.
The utility model content
The purpose of this utility model is the deficiency that exists for prior art, and a kind of minimizing impurities accumulation is provided, and avoids producing at sharp corner the rectangle heat radiating flat tube of micro-crack.
For achieving the above object, the utility model adopts following technical scheme:
A kind of cross section of rectangle heat radiating flat tube is rectangle, and four jiaos of rectangle are provided with circular arc chamfering, and the thickness at circular arc chamfering place is greater than the thickness of rectangle side.
This flat tube medial surface is provided with the wavy surface of fluctuating along the length direction of flat tube.
Compare with background technology, four ribs of the utility model rectangle heat radiating flat tube are provided with circular arc chamfering, arc chord angle meets fluid mechanics principle, the impurity herein that has reduced is piled up, keep the radiating efficiency of heat radiating flat tube unaffected, circular arc chamfering has reduced stress to be concentrated, and has avoided sharp corner to produce micro-crack, the thickness of circular arc chamfering has been strengthened its intensity and has further been avoided the crackle generation greater than the thickness of rectangle side; The flat tube medial surface is provided with the wavy surface of fluctuating along the length direction of flat tube, the contact area that has increased heat eliminating medium and rectangle heat radiating flat tube has improved radiating efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the another kind of structural representation of the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
The utility model discloses a kind of rectangle heat radiating flat tube.
As shown in Figure 1, a kind of cross section of rectangle heat radiating flat tube is rectangle, and four jiaos of rectangle are provided with circular arc chamfering 1, and the thickness at circular arc chamfering 1 place is greater than the thickness of rectangle side 2.
As shown in Figure 2 in order to improve the radiating efficiency of rectangle heat radiating flat tube, the cross section of this rectangle heat radiating flat tube is rectangle, four jiaos of rectangle are provided with circular arc chamfering 1, and the thickness at circular arc chamfering 1 place is greater than the thickness of rectangle side 2, and the flat tube medial surface is provided with the wavy surface 3 of fluctuating along the length direction of flat tube.
Claims (2)
1. rectangle heat radiating flat tube, it is characterized in that: the cross section of this flat tube is rectangle, and four jiaos of rectangle are provided with circular arc chamfering, and the thickness at circular arc chamfering place is greater than the thickness of rectangle side.
2. rectangle heat radiating flat tube according to claim 1, it is characterized in that: this flat tube medial surface is provided with the wavy surface of fluctuating along the length direction of flat tube.
