Abstract
The invention discloses a cooling fin with a bottom plate provided with sawtoothed structures and bosses. 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 bottom plate is provided with the bosses. 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 boss 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 boss 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 described base plate is provided with boss.
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.
The invention has the beneficial effects as follows: through actual test and use, have the fin of laciniation and boss to compare with the fin of plane structure on the base plate of the present invention, 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 boss 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.

Among the figure: 1, base plate, 2, the heat exchange pore, 3, trapezoid boss, 4, the rectangle boss.
The specific embodiment
Below in conjunction with accompanying drawing,, the structure of the fin of laciniation and boss is described in further detail being arranged on the base plate of the present invention.
As shown in Figure 1, the fin that laciniation and boss 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. 2, shown in Figure 3, near the air intake of nest plate type heat exchanger and base plate 1 edge of air side---be among Fig. 1 on, following both sides are laciniation, described base plate 1 is provided with boss, 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 air-flow direction settings of damming, the centre position in adjacent heat exchange tubes hole 2 is provided with the rectangle boss 4 of a vertical placement---be provided with the air-flow direction following current.
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; Boss structure on the base plate 1 has prevented to descend rapidly at the air fluid coefficient on heat exchanger tube surface effectively; Through actual test and use, there is the fin of laciniation and boss 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 boss 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.
