Abstract
The invention relates to the field of refrigerating systems, in particular to a corrugated cooling fin for a parallel flow evaporator. The corrugated cooling fin comprises a corrugated substrate, flanged holes arranged according to linear arrays are formed in the substrate, a flange is arranged at the upper portion of each flanged hole, a counter-bored hole is formed in the lower portion of each flanged hole, and the shape of the flanges is matched with that of the counter-bored holes. A main material of the cooling fin is hydrophilic aluminum foil, so that the hydrophily and heat exchange effect of the cooling fin are greatly improved, the cooling fin is perfectly matched with another cooling fin through the flanges and the bottom counter-bored holes, and the problems that after tube expansion, the cooling fin is unevenly stressed, and consequently tilting and tube leakage are caused are solved; besides, the corrugated cooling fin enlarges the heat exchange area, has a flow turbulence effect on media, increases the heat transfer coefficient, is used for the parallel flow evaporator and can improve heat exchange efficiency.
Description
Technical field
The present invention relates to field of refrigeration, be specially a kind of parallel-flow evaporator corrugate fin.
Background technology
Parallel-flow evaporator and condenser have compact, efficient feature, are widely used in air conditioning for automobiles.The basic element of character-fin as heat radiation is the core of parallel-flow evaporator and condenser transferring heat, and the shape of fin surface and the connected mode between fin and fin directly affect heat dispersion.
The fin majority manufacturing all kinds of parallel-flow evaporator and condenser is now flat plate, and the connection of flat plate refrigeration pipe, by tube expanding joint, connects without any contact between flat plate with flat plate, and this connected mode causes following ill effect:
1, be independently between each flat plate after expand tube, expand tube rear plate sheet not only can also can be seen by dilapidated even inner pipeline, directly affects the outward appearance of parallel-flow evaporator and condenser.
2, plate radiating plate enhanced heat exchange area is less, and plate radiating plate does not have flow-disturbing effect to medium, and heat transfer coefficient is less.
Summary of the invention
The object of the invention is to overcome above-mentioned defect of the prior art, provide area of dissipation to increase, a kind of parallel-flow evaporator corrugate fin that can perfect be connected between sheet with sheet.
For solving the problems of the technologies described above, the present invention takes following technical scheme:
A kind of parallel-flow evaporator corrugate fin, comprise in undulatory substrate, be provided with the flanging bore according to linear array arrangement on the substrate, described flanging bore top is provided with flange, bottom is provided with counterbore, and described flange and described counterbore shape match.
Preferably, described substrate is hydrophilic aluminium foil, and its thickness is 1.2-1.5mm.
Preferably, the height of described flanging bore is 1.3-1.5mm.
Preferably, the horizontal spacing between described flanging bore is greater than 18mm, and longitudinal pitch is greater than 21mm.
Preferably, the flange radius of described flanging bore is 0.4-1.38mm.
Compared with prior art, beneficial effect of the present invention is:
Fin of the present invention adopts material of main part to be hydrophilic aluminium foil, greatly improve hydrophily and the heat transfer effect of fin, perfectly assembled by flange and bottom counterbore between fin and fin, the inclination that there will not be fin to cause due to unbalance stress after expand tube and fistulae etc. are bad, in addition, its corrugate fin enhances and changes area and have flow-disturbing effect to medium, improves heat transfer coefficient, for improving heat exchange efficiency in parallel-flow evaporator.
