Abstract
The invention relates to a composite aluminum alloy radiator with a novel radiating fin cover. A radiating fin cover is arranged on the end part of the radiating fin, and an air convection channel is arranged on the front and back faces of the radiating fin cover. The air convection channel on the front face of the radiating fin cover inclines upwards, and forms a angle with 60-75 degrees with the radiating fin; the air convection channel on the back face of the radiating fin cover uplifts and inclines towards the radiator, the upper surface of the radiating fin cover is parallel to a collecting box pipe or inclines slightly; or the air convection channel on the front and back faces of the radiating fin cover uplifts and slightly inclines towards the radiator, and the upper surface of the radiating fin cover is parallel to a collecting box pipe; the radiating fin cover is formed by adopting an integrated compression casting, and the radiating fin cover is welded with the radiator main body or passed and buckled into a whole. The invention has the advantages that the design is reasonable, the process is simple, the process is simple, the cooling performance is good, the thermal efficiency is high, the equipment investment is small, and the cost is low.
Description
Technical field
The present invention relates to a kind of radiator, particularly a kind of Al-alloy radiator with heat sinking sheet cover.
Background technology
In miscellaneous radiator, a kind of Al-alloy radiator is arranged, its header tube and perpendicular radiating tube use steel pipe or copper pipe, and fin uses aluminum alloy materials.Al-alloy radiator on the domestic market has two kinds of structures at present, a kind of is the external Al-alloy radiator of producing, it links into an integrated entity as internal lining pipe with header tube and perpendicular radiating tube, aluminum alloy heat sink in the die casting outside internal lining pipe, make internal lining pipe and fin form the radiator fin of an one, as required a plurality of radiator fins are linked into an integrated entity, form a complete radiator.The advantage of this radiator is that production technology is simple, and radiator integral is good, and promptly all there is the cross-ventilation channel side of the front of radiator fin and the back side, radiator fin between two radiator fins, makes the perfect heat-dissipating of radiator, thermal efficiency height; The shortcoming of this radiator is that the die casting of a radiator fin can only be produced a kind of radiator fin of size, when needing to produce the radiator of multiple dimensions, just needs multiple kinds of molds, cause mould too many, the mould investment is too big, makes the entire product cost too high, and the market sale price is too high.Also having a kind of is the Al-alloy radiator of domestic production, it with aluminium section bar as fin, in the aluminium section bar hole, insert perpendicular radiating tube and make fin combine closely into radiator fin with perpendicular radiating tube by reaming equipment, as required a plurality of radiator fins and header tube are combined into radiator body again, the aluminium section bar radiating fin cover is installed at last, forms a complete radiator.Though the more preceding a kind of complexity of this radiator production technology, it can reduce the mould investment in a large number, reduces production costs greatly, and the market price is also low.Shortcoming is that this aluminium section bar radiating fin cover only is provided with the cross-ventilation channel two sides, and front and back does not have the cross-ventilation channel, makes the heat dispersion of radiator poor, and the thermal efficiency is low; Increase the cross-ventilation channel, improve heat dispersion, just need so just increase production process, improved production cost in the front and back punching of radiating fin cover.
Summary of the invention
For overcoming the defective of prior art, the invention provides that a kind of reasonable in design, technology is simple, the Al-alloy radiator of perfect heat-dissipating, thermal efficiency height, equipment investment is few, cost is low band heat sinking sheet cover.
A kind of Al-alloy radiator with heat sinking sheet cover is provided with radiating fin cover in fin ends, and the front and back of radiating fin cover all is provided with air convection channel.
The air convection channel in described radiating fin cover front is tilted to, and becomes 60-75 degree angle between the fin; The air convection channel at the radiating fin cover back side upwards and slightly tilts to radiator, or the slightly inclination parallel with header tube of radiating fin cover upper surface.
The air convection channel of described radiating fin cover front and back upwards and slightly tilts to radiator, and the radiating fin cover upper surface is parallel with header tube.
A kind of manufacture method of the Al-alloy radiator with heat sinking sheet cover, described radiating fin cover adopts the integral die-cast moulding, with this radiating fin cover and radiator body welding or bond or be buckled into one.
The production technology of production technology of the present invention and domestic existing Al-alloy radiator is basic identical, and difference is that radiating fin cover adopts the integral die-cast moulding, with this radiating fin cover and radiator body welding or bond or be buckled into one.
Because the front and back in radiating fin cover all is provided with air convection channel, thereby increased the cross-ventilation ability, improved the heat dispersion and the thermal efficiency, made the thermal efficiency of radiator improve about 15%, production cost and domestic existing Al-alloy radiator are about the same.Compare with external radiator fin integral die-cast, not only production technology is simplified, and is not subjected to the restriction of fin length size, has reduced number of molds in a large number, has saved the mould investment.
That the present invention has is reasonable in design, technology simple, perfect heat-dissipating, thermal efficiency height, equipment investment is few, cost is low characteristics.

The specific embodiment
Embodiment 1: a kind of Al-alloy radiator with heat sinking sheet cover, and structure is provided with radiating fin cover in fin ends as shown in Figure 1, and the front 1 and the back side 2 of radiating fin cover all are provided with air convection channel 4.
The air convection channel 4 in described radiating fin cover front is tilted to, and becomes 60-75 degree angle between the fin; The air convection channel at the radiating fin cover back side upwards and slightly tilts to radiator, and radiating fin cover upper surface 4 is parallel with header tube.
Described radiating fin cover adopts the integral die-cast moulding, and this radiating fin cover and radiator body is integrally welded.
Embodiment 2: production technology is identical with embodiment 1, basic structure is also identical with embodiment 1, as shown in Figure 2, difference is: the air convection channel of described radiating fin cover front and back upwards and slightly tilts to radiator, and radiating fin cover upper surface 4 is parallel with header tube.
Radiating fin cover and radiator body are bonded to one.
Embodiment 3: production technology is identical with embodiment 1, and basic structure also embodiment 1 is identical, and as shown in Figure 3, difference is: the air convection channel 4 in described radiating fin cover front is tilted to, and becomes 60-75 degree angle between the fin; The air convection channel at the radiating fin cover back side upwards and slightly tilts to radiator, slightly tilts between radiating fin cover upper surface 4 and the header tube.
