Abstract
The utility model relates to a fin, which is characterized in that the fin has a flat and smooth corrugated belt shape. A parallel flow heat exchanger disclosed by the utility model comprises an input tube, an output tube, more than two fins, a first collecting tube, a second collecting tube, and more than two flat tubes, wherein the flat tubes are welded between the first and the second collecting tubes in parallel and is communicated with the first and the second collecting tubes, the input and the output tubes are respectively welded at the upper and the lower parts of the outer side of the first collecting tube, and the fins are welded between the adjacent flat tubes. The fin and the parallel flow heat exchanger adopting the same are characterized in that the fin has the flat and smooth corrugated belt shape. The fin and the parallel flow heat exchanger adopting the fin greatly reduces the blocking probability of a fin air flue, so the air resistance is benefited to being reduced, the blowing volume of the heat exchanger is increased, the heat exchange efficiency of the heat exchanger is effectively ensured, so an air conditioner can stably operate for a long time.
Description
Technical field
The utility model relates to a kind of fin and adopts the parallel-flow heat exchanger of this fin, belongs to fin and adopts the improvement technology of the parallel-flow heat exchanger of this fin.
Background technology
At present, the outdoor heat converter of commercially available air-conditioner product is not generally installed screen pack, time has been grown, the fin of heat exchanger and coil surface will be amassed the last layer dust, if in the bigger environment of flue dust, move, laying dust can be faster more serious, thereby the heat exchange efficiency of air-conditioner outdoor unit heat exchanger is reduced greatly, and then have influence on the operational effect of air conditioner; For the air-conditioner product that adopts parallel-flow heat exchanger, because of the compact conformation of its parallel-flow heat exchanger, the air channel is narrower, and air quantity is little, in case laying dust, can make air quantity littler, even stop up the air channel, solve the laying dust problem if add filtering screen, then the air quantity influence that can be subjected to filtering screen becomes littler, need expanded motor power to improve air quantity, finally cause the efficiency of complete machine to reduce, be unfavorable for energy-conserving and environment-protective; If do not add filtering screen, early stage operational effect can be better than adding filtering screen, but because the fin of existing parallel-flow heat exchanger mostly is and cracks or be provided with structure such as wind guiding louver, of long duration, laying dust can increase gradually, causes the windage of heat exchanger to become big, air quantity by heat exchanger diminishes, the efficiency of complete machine reduces gradually, and laying dust can stop up the air channel fully when serious, causes the complete machine operation troubles.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and a kind of simplicity of design is provided, helps reducing laying dust and the air channel is stopped up probability, increases by air quantity, guaranteed the fin of heat exchange efficiency and adopt the parallel-flow heat exchanger of this fin.
The technical solution of the utility model is: a kind of fin is characterized in that described fin is smooth smooth ripple band shape.
A kind of parallel-flow heat exchanger, comprise input pipe, efferent duct, two above fins, first header, second header, two above flat tubes, wherein flat tube is welded in parallel between first header and second header and with first header and second header and is communicated with, input pipe, efferent duct are welded on the upper and lower in first header outside respectively, fin is welded between the adjacent flat tube, it is characterized in that described fin is smooth smooth ripple band shape.
Device has the barrier flaps that plays baffling, decision heat exchanger flow circuit more than in described first header and/or second header.
The utility model is owing to adopted the banded fin structure of smooth smooth ripple and this fin has been used for parallel-flow heat exchanger, laying dust is difficult to be deposited on smooth fin surface and is easy to fly away with the wind or is fallen by rain drop erosion, reduced the obstruction probability in fin air channel greatly, help reducing windage, increase the air quantity that passes through of heat exchanger, effectively guaranteed the heat exchange efficiency of heat exchanger, made the operation that air-conditioner can be steady in a long-term.

Fig. 2 is the structural representation of the utility model parallel-flow heat exchanger.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the utility model fin 3 is smooth smooth ripple band shape.
As shown in Figure 2, adopt the parallel-flow heat exchanger of above-mentioned fin 3, comprise input pipe 1, efferent duct 7, two above fins 3, first header 2, second header 8, two above flat tubes 4, wherein flat tube 4 is welded in parallel between first header 2 and second header 8 and with first header 2 and second header 8 and is communicated with, input pipe 1, efferent duct 7 are welded on the upper and lower in first header, 2 outsides respectively, fin 3 is welded between the adjacent flat tube 4, and is smooth smooth ripple band shape.
Device has the barrier flaps 6 that plays baffling, decision heat exchanger flow circuit more than in described first header 2 and/or second header 8.In the present embodiment, device has a barrier flaps 6 that plays baffling, decision heat exchanger flow circuit in first header 2.
Claims (3)
1. a fin is characterized in that described fin (3) is smooth smooth ripple band shape.
2. parallel-flow heat exchanger, comprise input pipe (1), efferent duct (7), two above fins (3), first header (2), second header (8), article two, above flat tube (4), wherein flat tube (4) is welded in parallel between first header (2) and second header (8) and with first header (2) and second header (8) and is communicated with, input pipe (1), efferent duct (7) is welded on the upper and lower in first header (2) outside respectively, fin (3) is welded between the adjacent flat tube (4), it is characterized in that described fin (3) is smooth smooth ripple band shape.
