Abstract
The invention discloses a cooling fin with a bottom plate provided with sawtoothed structures and arc protruded layers. The cooling fin comprises the bottom plate which is provided with a plurality of heat exchange pipe holes; the edges of the bottom plate near the air inlet and outlet sides of a washer heat exchanger are provided with sawtoothed structures; and the periphery of each heat exchange pipe hole is provided with a circle of arc protruded layer. The cooling fin is suitable for the washer heat exchanger.
Description
Technical field
The invention belongs to the technical field of heat exchanger, relate in particular to a kind of fin of nest plate type heat exchanger.
Background technology
The core of nest plate type heat exchanger comprises the heat exchanger tube that is positioned at the center, and the two ends of heat exchanger tube are fixed with tube sheet, is densely covered with fin between two tube sheets, and described fin is sleeved on the heat exchanger tube.Fin is one of main thermal component in the nest plate type heat exchanger.Fin in the nest plate type heat exchanger of present domestic most of manufacturer production, comprise base plate, base plate is provided with several heat exchange pores, and described base plate is a plane base plate, air is the advection state when flowing through this kind fin, cause radiating effect undesirable; And fin and the heat exchanger tube applying rate after dilating is generally lower, can only reach between 75%～85%, and heat exchange effect is relatively poor.
Summary of the invention
Technical problem to be solved by this invention is: the fin that laciniation and arc convex layer are arranged on a kind of better base plate of radiating effect that can make the nest plate type heat exchanger will be provided.
For addressing the above problem, the technical solution used in the present invention is: the fin that laciniation and arc convex layer are arranged on the base plate, comprise base plate, base plate is provided with several heat exchange pores, near the air intake of nest plate type heat exchanger and the bottom edge of air side is laciniation, and the outer periphery of described heat exchange pore is equipped with a circle arc convex layer.
Described arc convex layer is the convexity layer of half cycle sine wave shape.
The invention has the beneficial effects as follows: through actual test and use, there is the fin of laciniation and arc convex layer to compare on the base plate of the present invention with the fin of plane structure, surface heat transfer is led coefficient and is improved 32%～35%, and the heat exchange effect has improved 20%～30%; Have the applying rate after the fin of laciniation and arc convex layer and heat exchanger tube dilate to reach between 90%～94.8% on the base plate of the present invention, heat exchange effect is significantly increased.

The specific embodiment
Below in conjunction with accompanying drawing, the structure of fin that laciniation and arc convex layer are arranged on the base plate of the present invention is described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3, the fin that laciniation and arc convex layer are arranged on the base plate, comprise base plate 1, evenly be provided with several heat exchange pores 2 on the base plate 1, as Fig. 4, shown in Figure 5, near the air intake of nest plate type heat exchanger and base plate 1 edge of air side---be that upper and lower both sides are laciniation among Fig. 1, the outer periphery of described heat exchange pore 2 is equipped with the arc convex layer 3 that a circle is the half cycle sine wave shape.
The invention has the beneficial effects as follows: the laciniation that is horizontally placed on the fin both sides in the air flow passage, when flowing air intake, disturbs air air is mobile, make the air air intake flow at the uniform velocity, disturbed " boundary-layer " effect of fin surface effectively, the thermal resistance of feasible " boundary-layer " is less, thermograde is less, more helps heat exchange, has also increased the rigidity at fin edge in addition, improved the shock resistance of fin, outward appearance is neat appearance more; Arc convex layer 3 not only can effectively be controlled the spacing of arranging between the adjacent fin, and can make that to have fin and being connected of heat exchanger tube preferably an expanded joint flexible, that make both tightr evenly; Through actual test and use, there is the fin of laciniation and arc convex layer to compare on the base plate of the present invention with the fin of plane structure, surface heat transfer is led coefficient and is improved 32%～35%, and the heat exchange effect has improved 20%～30%; Have the applying rate after the fin of laciniation and arc convex layer and heat exchanger tube dilate to reach between 90%～94.8% on the base plate of the present invention, heat exchange effect is significantly increased.
Claims (2)
