As shown in fig. 1, the heat dissipating fin of a refrigerator according to the present invention comprises a base plate 10, wherein the base plate 10 is provided with a plurality of through holes 11 for heat exchanging pipes to vertically pass through, and a plurality of longitudinal vortex generating units 20 are uniformly distributed on at least one side of the base plate 10. the longitudinal vortex generating units 20 comprise a main spoiler 21 and sub spoilers 22 arranged in parallel on both sides of the main spoiler 21. the main spoiler 21 and the sub spoilers 22 are both semi-circular structures, the centers of the main spoiler 21 and the sub spoilers 22 are collinear and the connecting line is perpendicular to the plane of the main spoiler 21. the radius R of the main spoiler 21 is three times the radius R of the sub spoilers 22, the distance D between the main spoiler 21 and the sub spoilers 22 is 4/5 of the radius R of the sub spoilers 22. the base plate 10 is an elliptical structure, the through holes 11 are uniformly arranged along the major axis, the included angle α between the plane of the main spoiler 21 and the minor axis is 50-70 degrees, the radius R is 5-7 mm, the radius R is 6.30mm, the radius R is 2.2.1-2 mm, the optimum included angle D is 632-3 cm, and the longitudinal vortex generating unit is an optimum included angle between the adjacent unit 2-20-3 cm.
A refrigerator radiating fin theory of operation lie in, the multi-disc fin parallel arrangement, pass the heat exchange tube of refrigerator in proper order behind all through-holes 11 and fix. The heat exchange pipe transfers energy to the longitudinal vortex generating unit 20 through the base plate 10. The air passes through the gap between the two substrates 10 in the flow, and the main spoiler 21 and the sub-spoiler 22 are perpendicular to the substrates 10, so that they can be supported with similar rigidity regardless of whether the air enters from the left side or the right side. The elliptical shape of the substrate 10 also aims to reduce the air-crack phenomenon. The design of the longitudinal vortex generating unit 20 with a high middle part and low two sides also enables the air flow to form a wave-shaped motion track, namely, the air flow is smooth and has a long enough stroke for heat exchange. The semicircular spoiler is also very easy to produce, and further the early-stage production cost is reduced. The smooth air flow can reduce noise and avoid squeal in high winds.
Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
