Abstract
The invention discloses a radiating fin of a plate-fin heat interchanger, comprising a base plate which is provided with a plurality of heat exchanging pipe holes; the edge of the base plate closing to the air inlet side and the air outlet side of the plate-fin heat interchanger is in a zigzag structure; the base plate is provided with a convex plate; an arc-shaped bulge layer is arranged on the periphery of the heat exchanging pipe holes. The radiating fin of the invention is suitable for plate-fin heat interchangers.
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 most domestic 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: a kind of fin that can make the better nest plate type heat exchanger of radiating effect of nest plate type heat exchanger will be provided.
For addressing the above problem; The technical scheme that the present invention adopts is: the fin of nest plate type heat exchanger; Comprise base plate, base plate is provided with several heat exchange pores, is laciniation near the air intake of nest plate type heat exchanger and the bottom edge of air side; Described base plate is provided with boss, and the outer periphery of described heat exchange pore is equipped with a circle arc convex layer.
Described boss comprises trapezoid boss and rectangle boss, and each heat exchanger tube orifice ring is to being provided with four trapezoid boss of laterally placing, and the centre position in adjacent heat exchange tubes hole is provided with a vertical rectangle boss of placing.
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, the fin of nest plate type heat exchanger of the present invention is compared with the fin of plane structure, and surface heat transfer is led coefficient and improved 32%～35%, and the heat exchange effect has improved 20%～30%; Applying rate after the fin of nest plate type heat exchanger of the present invention and heat exchanger tube dilate has reached between 90%～94.8%, and heat exchange effect is significantly increased.

The specific embodiment
Below in conjunction with accompanying drawing, the structure of the fin of nest plate type heat exchanger of the present invention is done further to describe in detail.
Like Fig. 1, Fig. 2, shown in Figure 3; The fin of nest plate type heat exchanger comprises base plate 1, evenly is provided with several heat exchange pores 2 on the base plate 1; Like 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, described base plate 1 is provided with boss, like Fig. 6, shown in Figure 7; Described boss comprises trapezoid boss 3 and rectangle boss 4; Each heat exchange pore 2 be arranged circumferentially four trapezoid boss of laterally placing 3---with air-flow direction settings of damming, the centre position in adjacent heat exchange tubes hole 2 is provided with a vertical rectangle boss 4 of placing---be provided with the air-flow direction following current, the outer periphery of described heat exchange pore 2 is equipped with one and encloses the arc convex layer 5 that is the half cycle sine wave shape.
The invention has the beneficial effects as follows: be horizontally placed on the laciniation of the fin both sides in the air flow passage, when air flows air intake, disturb, make the air air intake flow at the uniform velocity air is mobile; 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; Boss structure on the base plate 1 has prevented to descend rapidly at the air fluid coefficient on heat exchanger tube surface effectively; Arc convex layer 5 not only can effectively be controlled the spacing of arranging between the adjacent fin, and can make and have fin and being connected of heat exchanger tube preferably flexible, as to make both expanded joint more closely evenly; Through actual test and use, the fin of nest plate type heat exchanger of the present invention is compared with the fin of plane structure, and surface heat transfer is led coefficient and improved 32%～35%, and the heat exchange effect has improved 20%～30%; Applying rate after the fin of nest plate type heat exchanger of the present invention and heat exchanger tube dilate has reached between 90%～94.8%, and heat exchange effect is significantly increased.
