Embodiment
As Figure 1-4, the present invention provides a kind of heat exchanger, it includes the heat exchange fin 1 of the ripple sheet form with multiple crests and multiple troughs, and it is arranged on the heat exchanger tube 2 between adjacent peaks, it is a train wave line from the scope comprising a crest to next crest and not comprising next crest, angle formed by the crest location of each column ripple is that the inclination angle of the train wave line (is less than or equal to the angle of 180 degree, positioned at the angle of the lower section of fin 1 i.e. in figure), vertical range between the crest and trough of each column ripple is its wave height, and there is the number of degrees size at multiple inclination angles incomplete same, multiple wave height sizes are also not completely equivalent.
Pass through the heat exchanger of the present invention, by the angle and wave height between heat-exchanger ripple piece crest location, by original each angle is identical and wave height is equal, it is changed into incomplete same along fluid flow direction angle, the structure type that wave height size is not completely equivalent, when gas skims over the uniform corrugated plate in inclination angle, because the uneven disturbance to air-flow on corrugated plate surface is strong, heat transfer process is violent, make thermo parameters method more disorderly, heat transfer process is also more violent, improve heat transfer effect, therefore compared to the uniform corrugated plate in inclination angle in the prior art, the heat exchanger of the present invention has more preferable heat transfer effect, improve the heat exchange property of complete machine.
Preferably, the number of degrees size at multiple inclination angles is in the flow direction along air-flow, for the structure type and arrangement (as shown in Figure 2) gradually successively decreased；Or the number of degrees size at multiple inclination angles is in the flow direction along air-flow, for one section of subtract one section structure type and arrangement (as shown in Figure 4) for increasing；Or in the ripple scope residing for a heat exchanger tube 2, the inclination angle of the upstream position in the flow direction along air-flow, the inclination angle of two neighboring ripple is more than the inclination angle (as shown in Figure 3) of downstream position.This is the different inclination angle arrangement of three kinds of the heat exchanger of the present invention, i.e. in the flow direction of air-flow, the structure type that inclination angle is arranged to gradually successively decrease, enable to wave height to form gradually incremental structure in this direction, so strong disturbance can be more preferably formed to air-flow, such that heat transfer effect is strengthened to greatest extent；Inclination angle is arranged to gradually incremental structure type, it is also possible that wave height forms the structure gradually successively decreased in this direction, can strengthen disturbance to air-flow relative to the uniform situation in inclination angle, such that thermo parameters method is disorderly, improve heat transfer effect；By the structure type that inclination angle is arranged to part increasing, a part subtracts, wave height can be caused to form the structure that leading portion subtracts, back segment increases in air current flow direction, also the disturbance to air-flow is strengthened so that thermo parameters method becomes more disorderly, improves the effect of heat exchange.
Preferably, the heat exchanger tube 2 is divided to arrangement architecture of the row in two rows, and the distance of a train wave line is spaced between two row's heat exchanger tubes.It is divided to heat exchanger tube to preferred arrangement form and frame mode of the row into the arrangement architecture of two rows is heat exchanger tube, and the distance for a train wave line being spaced between two row's heat exchanger tubes, enable to be unlikely between two row's heat exchanger tubes every it is too remote and reduce the heat exchange action effect of heat exchanger, also be unlikely to make the two every it is too near and cause air current flow resistance excessive and cause air flow rate too slow, and the position that heat exchanger tube is just arranged in a row waviness width enables to air-flow to flow through heat exchange fin reinforcement heat transfer effect to greatest extent, and open up the fairly simple convenience of heat exchanging holes.
