Abstract
The utility model discloses a radiating fin with a bottom plate provided with a boss and an arc-shaped raised layer. The radiating fin comprises the bottom plate, the bottom plate is provided with a plurality of heat exchange tube holes and the boss, and the peripheries of the heat exchange tube holes are provided with a circle of arc-shaped raised layer. The radiating fin is applicable to a plate fin heat exchanger.
Description
Technical field
The utility model belongs to the technical field of heat exchanger, relates 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.
The utility model content
Technical problem to be solved in the utility model is: the fin that boss 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 adopted in the utility model is: the fin of boss and arc convex layer is arranged on the base plate, comprise base plate, base plate is provided with several heat exchange pores, 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 beneficial effects of the utility model are: through actual test and use, there is the fin of boss and arc convex layer to compare on the utility model base plate 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 boss and arc convex layer and heat exchanger tube dilate to reach between 90%～94.8% on the utility model base plate, heat exchange effect is significantly increased.

Among the figure: 1, base plate, 2, the heat exchange pore, 3, trapezoid boss, 4, the rectangle boss, 5, the arc convex layer.
The specific embodiment
Below in conjunction with accompanying drawing, the structure of fin that boss and arc convex layer are arranged on the utility model base plate is described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3, the fin that boss 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, 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 the air-flow direction setting of damming, the centre position in adjacent heat exchange tubes hole 2 is provided with a vertical rectangle boss 4 of placing---and be provided with the air-flow direction following current, the outer periphery of described heat exchange pore 2 is equipped with the arc convex layer 5 that a circle is the half cycle sine wave shape.
The beneficial effects of the utility model are: the boss structure on the base plate 1 has prevented the air fluid coefficient rapid decrease on the heat exchanger tube surface effectively; Arc protruded layers 5 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 boss and arc protruded layers to compare with the fin of plane structure on the utility model base plate, surface heat transfer is led coefficient and is improved 32%～35%, and heat transfer effect has improved 20%～30%; Have the applying rate after the fin of boss and arc protruded layers and heat exchanger tube dilate to reach between 90%～94.8% on the utility model base plate, heat exchange effect is significantly increased.
