Description
Technical field
The present invention relates to a kind of vortex array heat-exchanger rig, particularly relate to a kind of equilateral triangle arrangement to whirlpool row array row heat-exchanger rig.
Background technology
Vortex motion is a kind of phenomenon that nature exists, and owing to its main flow does not the most change direction, thus flow resistance is less.A lot of example applying helical vortex is had, such as distorted elliptical heat exchange of heat pipe, thread groove tube heat exchanger and spiral baffle heat exchanger etc. in heat transfer enhancement technology field.
The most commonly used heat transfer vortex array heat-exchanger rig is all along whirlpool scheme, the vortex direction of the most all heat transfer vortexes is identical, although rotation direction is the same for separating the fluid in pipe, but for the fluid being centered around outside pipe, owing in the helical duct of adjacent 2 the heat transfer vortex the tangent arranged along whirlpool, the flow direction of fluid is contrary, the loss that the swash of wave inevitably results in fluid flow momentum and energy formed, finally will result in the reduction of the coefficient of heat transfer or the raising of flow resistance.Although having the application to reverse vortex in the machinery occasion such as double-screw compressor or oil pump, but the problems in role of vortex direction of rotation of regrettably conducting heat in field of heat transfer is both at home and abroad the most not yet to heat transfer vortex array being made relevant research or effectively utilizes.
Summary of the invention
The present invention provide a kind of equilateral triangle arrangement to whirlpool row array row heat-exchanger rig.
The present invention adopts the following technical scheme that
A kind of equilateral triangle arrangement to whirlpool row array row heat-exchanger rig, including cylindrical shell, in circular cylindrical shell body, be provided with heat transfer core body；Described heat transfer core body includes suitable whirlpool arrangement (the most adjacent heat transfer vortex vortex direction is consistent) Y shape heat transfer vortex row in Y-shaped；Described Y shape heat transfer vortex row be centrally located on cylindrical shell central point, and the angle between the adjacent two-arm of Y shape is 120 °；Heat transfer vortex array it is provided with in the sector that the adjacent two-arm of each Y shape is constituted, described heat transfer vortex array is made up of dextrorotation V-arrangement heat transfer vortex row and the left-handed V-arrangement heat transfer vortex row arranged along whirlpool according to V-shaped, and the angle between the two-arm of described dextrorotation or left-handed V-arrangement heat transfer vortex row is 120 °；The heat transfer vortex rotary orientation in V-arrangement heat transfer vortex row adjacent with Y shape heat transfer vortex row and the heat transfer vortex rotary orientation in Y shape heat transfer vortex row are contrary, the heat transfer vortex rotary orientation contrary (i.e. arranging whirlpool) in adjacent two row's V-arrangement heat transfer vortex rows of each heat transfer vortex array.
Compared with prior art, present invention have the advantage that
1) for the heat transfer vortex array heat exchanger being made up of multiple local vortex, 2 direction of rotation contrary adjacent heat transfer vortex flow direction in its tangent passage is consistent, thus can be formed with joint efforts, be conducive to strengthening heat-transfer effect and reducing flow resistance.Fig. 4 is shown that a pair contrary adjacent heat transfer vortex of rotary orientation i.e. to whirlpool heat transfer vortex, when the fluids that two strands of helical ducts respectively along adjacent heat transfer vortex flow occur to converge in the passage of two heat transfer vortex the tangent when (see the dotted line circle of Fig. 4 in arrow shown in), flowing to of two fluids is identical；And for the adjacent heat transfer vortex that existing rotary orientation is identical i.e. conducts heat vortex along whirlpool, when the fluids that two strands of helical ducts respectively along adjacent heat transfer vortex flow occur to converge in the passage of two heat transfer vortex the tangent when (see the dotted line circle of Fig. 5 in arrow shown in), the flow direction of two fluids is on the contrary, formed the swash of wave, and the swash of wave can be produced dissipation.The visible present invention utilizes heat transfer vortex adjacent to whirlpool two fluids in the passage of the tangent to occur to flow to identical feature when converging, flow resistance can be reduced, and beneficially augmentation of heat transfer, the heat transfer vortex quantity that simultaneously can meet again 2 vortex directions is of substantially equal.
2) it is typically identical due to the manufacturing cost of different directions heat transfer vortex, thus the present invention's is a kind of technical scheme having notable augmentation of heat transfer effect under conditions of increasing cost hardly to whirlpool formula square heat transfer vortex array heat exchanger, layout and manufacture can be facilitated.
3) play the mastery reaction to whirlpool during the present invention can be implemented in equilateral triangle arrangement scheme as far as possible, thus except heat transfer vortex and the heat transfer vortex about of central point formed 3 along whirlpools and 3 to whirlpool in addition to, described equilateral triangle grid arrange heat transfer to whirlpool array in around certain internal heat transfer vortex flowing fluid, its flow direction all with around 4 directions in 6 directions about adjacent heat transfer vortex flow fluid formed flow direction consistent to whirlpool, be conducive to augmentation of heat transfer and reduce flow resistance, the heat transfer vortex quantity that simultaneously can meet again 2 vortex directions is of substantially equal, and facilitate layout and manufacture.The field such as nuclear reactor, distorted elliptical heat exchange of heat pipe that is listed in whirlpool row array of equilateral triangle arrangement has wide practical use.
4) the present invention is directed to equilateral triangle arrangement arrangement, the program is not only compacter under same pipe centre-to-centre spacing compared with square stringing scheme, and fluid always forms staggered arrangement flowing, and heat transfer coefficient is higher；The distance being more uniformly distributed can be kept with inwall, so most of heat exchanger all uses equilateral triangle stringing scheme in circular cylindrical shell body.
