Abstract
The invention provides a finned flat tube heat exchanger with four plane vortex generators on each flat tube and relates to the technical field of finned tube heat exchangers. The finned flat tube heat exchanger comprises heat exchange tubes arranged in the gas flow direction and fins sleeved on the heat exchange tubes; the heat exchange tubes arranged in the gas flow direction are flat tubes; holes for allowing the flat tubes to be sleeved in are formed on the fins; two pairs of upward triangular small wing type vortex generators are respectively punched on the upper sides and the lower sides of the holes, triangular holes are formed on the fins; the front edge points of the first pair of vortex generators are respectively positioned on tangents at the front ends of the holes; and the front edges of the second pair of vortex generators are positioned on middle vertical lines of the holes. The number of the vortex generators on the surfaces of the fins is less; the four vortex generators are regularly arranged nearby each flat tube; and compared with a shutter, a ripple, a slotted fin and other punching moulds, the finned flat tube heat exchanger is simpler. The vortex generators on the fins can generate vortex in the main flow to cause secondary flow, so that the purpose of increasing the mixing degree of cold and heat fluids to play a role in strengthening heat transfer is achieved.
Description
Technical field
The present invention relates to manage the wing technical field of heat exchangers, whirlpool, particularly a kind of four planes of every flat tube generator formula flat tube pipe wing heat exchanger.
Background technology
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.
No matter pipe or flat tube pipe wing heat exchanger, general liquid working substance flows in pipe, and gas because the specific heat of gas is very little, makes that the thermal resistance in diabatic process mainly concentrates on the gas side in the pipe flows outside.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, is used widely at industry-by-industry.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 economy simultaneously makes the area of fin ad infinitum not increase.In order further to improve the heat transfer property of 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.
Flat tube pipe wing heat exchanger have flow channel change mild, can effectively reduce the gas side liquid flow resistance, cut down the consumption of energy.Existing studies show that at the vortex flux of flat tube pipe wing heat exchanger gas side main flow direction more much smaller than pipe pipe wing heat exchanger gas side.So flat tube pipe wing is more suitable for adopting the whirlpool generator to strengthen the vortex flux of main flow direction.And the influence of the position of cast and whirlpool generator and optimization of geometric parameters combination heat exchanging device combination property thereof is very important.For example, for multi coil wing heat exchanger, can being interfered in the downstream decay and with the whirlpool in downstream or superpose by the shape of a hoof whirlpool that vertical whirlpool reaches and cast is induced that the whirlpool generator produces in the upstream, obviously influences the exchange capability of heat of fin.In order further to improve the heat exchange property of flat tube pipe fin-type, be necessary very much further to optimize parameter combinations, design efficient low-resistance heat exchanger fin type.
Summary of the invention
Technical problem to be solved by this invention provides a kind of whirlpool, four planes of every flat tube generator formula flat tube pipe wing heat exchanger that reduces flow resistance, cuts down the consumption of energy, improves the fin exchange capability of heat.
The present invention adopts following technical proposals to solve the problems of the technologies described above:
Whirlpool, four planes of a kind of every flat tube generator formula flat tube pipe wing heat exchanger, comprise along gas flow direction heat exchanger tube of arranging and the fin that is enclosed within on the heat exchanger tube, the described heat exchanger tube of arranging along gas flow direction is a flat tube, on fin, be provided with the hole of suit flat tube, the both sides up and down in each hole are the triangular form winglet formula whirlpool generator that makes progress of two pairs of punching presses respectively, and on fin, leave tri-angle-holed, the leading edge point of first pair of whirlpool generator lays respectively at the front end tangent line in hole, and the leading edge of second pair of whirlpool generator is positioned at the intermediate vertical line in hole.
Between the described whirlpool generator 1 horizontal spacing be 1.5～3.0 times of hole 5 width.
The ratio of the two right angle length of sides of described whirlpool generator 1 is 2.
The height of described whirlpool generator 1 equals 0.6～1.0 times of fin 4 spacings.
It is 115-135 ° that generator 1 base, described whirlpool and flow direction have an obtuse angle angle theta.
The present invention does not stamp out the flat tube pipe wing heat exchanger of whirlpool generator relatively on fin, heat transfer coefficient is big, the heat exchange efficiency height, and exchange capability of heat improves greatly, thereby makes flat tubular fin radiator combination property better, can save ample resources.The negligible amounts of the whirlpool generator of fin surface of the present invention has 4 and queueing discipline on each flat tube side, and diels such as shutter, ripple, slitted fin are also fairly simple relatively.Flat tube pipe wing heat exchanger of the present invention have flow channel change mild, more much smaller than pipe pipe wing heat exchanger gas side, can effectively reduce the gas side liquid flow resistance, cut down the consumption of energy.When fluid is flowed through the whirlpool generator, at whirlpool generator place and generator downstream, whirlpool can produce vertical whirlpool, in fluid, produce the secondary flow follow main flow.The secondary that is produced flows to the downstream and is delivered to than distant positions, makes the interior cold and hot gas of the outer gas passage of pipe constantly obtain mixing, and can improve the heat exchange property of fin surface effectively.Simultaneously two pairs of whirlpool generators have fixing position, eliminated vertical whirlpool that the upstream produces by the whirlpool generator and and the cast shape of a hoof whirlpool of inducing superpose in the decay in downstream and with the whirlpool in downstream, obviously improved the exchange capability of heat of heat exchanger.
