Abstract
The invention discloses a flat tube-fin heat exchanger with a double-side vortex generator, which belongs to the technical field of flat tube-fin heat exchangers and comprises flat tubes arranged along the direction of air flow and fins sleeved on the flat tubes. The fins are provided with holes used for sleeving the flat tubes, two pairs of vortex generators facing upwards and two pairs of vortex generators facing downwards are stamped respectively by the upper side and the lower side of each hole, and corresponding small holes are left on the fins; and the front edge points of the first pair of the vortex generators facing upwards are located at front-end tangent lines of the holes used for sleeving the flat tubes, and the front edge points of the second pair of the vortex generators facing upwards are located at middle perpendicular lines of the holes used for sleeving the flat tubes. Compared with a traditional single-side fin for stamping the vortex generators, two sides of the fins disclosed by the invention are simultaneously turned over to stamp out the vortex generators, thereby the heat exchange capability of the fins can be improved, and the flow resistance of an air side can be simultaneously reduced. Moreover, the compactedness of a heat exchange device is increased, the power of a pump is reduced, and the energy sources are saved under an identical heat load.
Description
Technical field
The present invention relates to flat tube pipe wing technical field of heat exchangers, particularly a kind of two-sided whirlpool generator formula flat tube pipe wing heat exchanger.
Background technology
The operating cost of pipe wing heat exchanger depends on the heat transfer property of pipe wing heat exchanger.In order to satisfy the requirement of energy-saving and emission-reduction, the augmentation of heat transfer of pipe wing heat exchanger is extremely important.The most suitable mobile device of flat tube pipe wing heat exchanger heat exchanger, such as radiator, the diesel locomotive heat exchanger, flat tube pipe wing heat exchanger can be corrugated tube type or sheet assemble, the former is more as plate-fin heat exchanger.If no special instructions, " pipe " refers generally to pipe in " pipe wing heat exchanger ", and the existing overwhelming majority only relates to pipe pipe wing heat exchanger about the patent of pipe wing Heat exchanger sheet type.And flat tube pipe wing heat exchanger and pipe pipe wing heat exchanger are at cylinder structure or all completely different aspect the heat exchanger manufacturing process.
For flat tube pipe wing heat exchanger commonly used, in the gas side fin being installed is to improve the effective measures of heat exchange with the thermal resistance that the increase heat exchange area reduces the air survey.But the difference of fin surface temperature and tube surface temperature has reduced heat exchange property along with increasing away from the increase of tube surface distance, and the restriction that also is subjected to simultaneously economy makes the increase that the area of fin can not be unlimited.The existing flat tube pipe wing that studies show that is more suitable for adopting the whirlpool generator to strengthen the vortex flux of main flow direction.In order further to improve the heat transfer property of flat tube pipe wing heat exchanger, at fin surface the whirlpool generator being set is a kind of effective augmentation of heat transfer measure.In fluid, can produce whirlpool at the whirlpool generator that fin surface stamps out, cause secondary flow, promote the mixing between cold fluid and hot fluid, can strengthen the heat exchange property of fin surface effectively.
The heat conduction reinforced means of existing fin surface have corrugated fin, slitted fin, louvered fin, whirlpool generator formula and enhanced heat transfer fin such as combined, and these fins are followed the increase that causes flow resistance in enhanced heat exchange.Existing single face arranges that the generator formula enhanced heat exchange surface, whirlpool of whirlpool generator can strengthen the heat convection performance effectively, but flow resistance also increases along with the introducing of whirlpool generator simultaneously.For consuming under certain pump power, further improve the heat transfer property of whirlpool generator formula thermoexcell wing, can change the structure and the arrangement thereof of fin surface whirlpool generator.
Summary of the invention
Technical problem to be solved by this invention provides a kind of two-sided whirlpool generator formula flat tube pipe wing heat exchanger that can increase flat tube pipe wing heat exchanger gas side heat exchange property.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
A kind of two-sided whirlpool generator formula flat tube pipe wing heat exchanger, comprise along gas flow direction flat tube of arranging and the fin that is enclosed within on the flat tube, described fin is provided with the hole of suit flat tube, the both sides up and down in each hole are whirlpool generator and two pairs of downward whirlpool generators of making progress of two pairs of punching presses respectively, and stay corresponding aperture on fin; The leading edge point of first pair of whirlpool generator upwards is positioned at the front end tangent line in the hole of suit flat tube, and the leading edge point of the second pair of whirlpool generator that makes progress is positioned at the intermediate vertical line in the hole of suit flat tube.
Described whirlpool generator is a triangle, and four pairs of whirlpool generators are symmetrically distributed about the hole of suit flat tube in twos, with the width of hole at a distance of 1-2 hole doubly.
The length of two right-angle sides of described upper surface whirlpool generator and lower surface whirlpool generator is than being 2:1, and the height of whirlpool generator equates that with the spacing of fin height is 1:1 with the ratio of short right-angle side.
Described two pairs of downward whirlpool generators are arranged with two pairs of whirlpool generator equidistant intervals that make progress, and spacing is a 0.5-2.5 whirlpool generator length doubly.
The base of described upper surface whirlpool generator and lower surface whirlpool generator is 115-135 degree with the obtuse angle θ that comes flow path direction.
The present invention is owing to be furnished with the whirlpool generator at the passage upper and lower surface, make passage upper and lower surface just the both sides of fin and the heat transfer boundary condition between fluid all improve, can improve the heat exchange property of fin surface effectively.Simultaneously, on the fin of flat tube both sides to both sides after all flange stamps out the whirlpool generator, between flat tube and whirlpool generator, formed a fluid passage, make that fin surface is all constantly washed away around flat tube surface and the flat tube, make the cold fluid and hot fluid in the passage fully obtain blending, improved the heat transfer property between flat tube, fin and the fluid.Because the height of whirlpool generator is less, the fluid resistance loss of being brought is less, make heat exchanger plates cored structure of the present invention compare with the pipe wing plate core of single face punching press whirlpool generator, when improving heat exchange property, also reduce fluid resistance loss, improved heat exchange efficiency, increased the compactedness of heat transmission equipment, under identical thermic load, reduce pump power, saved the energy.The present invention does not have the flat tubular fin radiator of punching press whirlpool generator relatively, exchange capability of heat raising 50.9% (
Re=1600), the flat tube pipe fin structure of existing relatively single face punching press whirlpool generator, generator length is the same in the whirlpool, and under the height minus situation half as large, the heat radiation chip structure that the present invention proposes is flowing
ReNumber is 1900 o'clock (making shaping size with spacing of fin), and heat exchange property improves 28.2%, and resistance coefficient reduces by 13.5% simultaneously, has improved the heat exchange and the mobile performance of pipe wing widely.The present invention is furnished with undersized whirlpool generator at the upper and lower surface of flat tube pipe fin structure gas passage, just stamp out the whirlpool generator at the two sides of fin while flange, the sheet type of existing relatively single face punching press whirlpool generator, can when improving the fin exchange capability of heat, reduce the flow resistance of gas side, under identical thermic load, increase the compactedness of heat exchanger, reduced pump power.
