Description
Technical field
The utility model relates to field of heat exchangers, particularly relates to the wavy heat exchanger fin of a kind of rectangle.
Background technology
Heat exchanger, as a kind of high-efficiency heat exchanger equipment, has been widely used in the industry-by-industries such as HVAC, electric power, petrochemical industry, food pharmaceutical, boats and ships, Ferrous Metallurgy.Inner fin is the primary element in aluminum plate fin type radiator, the process of heat exchange mainly by the convection heat transfer' heat-transfer by convection between the hot conduction of inner fin and fin and fluid to outer fin, reject heat in air by outer fin again, reach and carry out cooling to engineering machinery with this.Inner fin, except bearing main heat radiation task, also plays the booster action between two dividing plates.Inner fin of the prior art generally adopts flat type fin, serrated fin.In heat exchanger, be generally but in the time of engineering mechanical device operation its working environment conventionally all very severe, in operation process usually with silt, flying upward of dust, these silts, dust is easy to be adsorbed on engineering machinery surface, if the heat exchanger of engineering machinery is the words that adopt water cooler and charge air cooler, aqueous medium is subject to the impact of environment larger, the just likely obstruction of inner fin of serrated fin in traditional heat exchanger, badly influence the performance of radiator and the service life of radiator, if use flat type fin, the coefficient of heat transfer of flat type fin can be lower, can not meet heat exchange property.
Utility model content
The utility model main purpose is to provide the wavy heat exchanger fin of a kind of rectangle, and the rectangular shape of this fin profile of tooth, is beneficial to vacuum brazing, and is applicable to severe engineer machinery operation environment, is difficult for stopping up, and extends the service life of heat exchanger.
For achieving the above object, the technical solution adopted in the utility model is: the wavy heat exchanger fin of a kind of rectangle, formed by metal substrate, described metal substrate is converted into the rectangular wavy conduit of some continuous cross sections, each conduit is overlooked rectangular, and some conduits are evenly distributed and adjacent conduit is parallel; On described each conduit, be evenly provided with some concave points and salient point, described salient point or described concave point are all triangular in shape; The equidistant interleaved setting of concave point on described each conduit and salient point.
Preferably, in described some conduits, the same position place on arbitrary neighborhood conduit is concave point or is salient point.
The wavy heat exchanger fin of rectangle described in the utility model is on the basis of flat type fin, to be pressed into certain concaveconvex shape, while running into concave point place/salient point place when medium is flowed in passage, constantly change flow direction, to actuate the turbulence of medium, separate or thermal boundary layer, its effect is equivalent to fractureing of fin, and its heat transfer property just improves.And fin of the present utility model is punching fin, the orthogonal shape of profile of tooth, the support force of rectangular teeth guarantees the requirement of vacuum brazing effectively, the product soldering first passage rate of using instead after fin reaches 91.2%, has effectively guaranteed the quality of product.
Preferably, on described each conduit, be salient point to the position of a side direction projection, be concave point to the position of opposite side direction projection; The height of projection of described salient point is identical with the recessed height of described concave point.
Preferably, the spacing between described two adjacent salient points or two adjacent concave points is between 25mm-45mm.Run into concave point place/salient point place when clearing up for convenience and facilitating medium to flow in passage time, change flow direction, to promote the turbulence of medium, consider heat exchanger fin situation, preferred in the utility model, the spacing between described two adjacent salient points or two adjacent concave points is 31.8mm.
Preferably, the height of the wavy heat exchanger fin of described rectangle is between 5.00mm-7.00mm.Further preferred, the height of the wavy heat exchanger fin of described rectangle is between 6.00-6.80mm.
Preferably, the pitch of the wavy heat exchanger fin of described rectangle is between 2.00mm-3.00mm.Further preferred, the pitch of described fin is between 2.00-2.80mm.
Preferably, the thickness of described metal substrate is between 0.050mm-0.250mm.Further preferred, the thickness of described metal substrate is 0.152mm.
Preferably, described metal substrate is made up of metallic aluminium.
In the actual use of heat exchanger, if when inner fin adopts sawtooth pattern or flat type fin, due to engineer machinery operation environment very severe, dust, sand, rainwater all can be adsorbed onto on radiator, aqueous medium easily pollutes, and easily causes the obstruction of zigzag inner fin, badly influences the performance of radiator and the service life of radiator, although and the good cleaning of flat type fin, radiating effect is bad; The wavy heat exchanger fin of rectangle described in the utility model has solved the problems referred to above effectively, not only good heat dissipation effect, and easy to clean extends the service life of product greatly.
The beneficial effects of the utility model are: the wavy heat exchanger fin of the utility model rectangle, the rectangular shape of this fin profile of tooth, is beneficial to vacuum brazing, and is applicable to severe engineer machinery operation environment, is difficult for stopping up, and extends the service life of heat exchanger.
