CN201527212U - High-efficient strengthened anti-vibration radiating fin - Google Patents

Abstract

The utility model relates to a high-efficient strengthened anti-vibration radiating fin used in heat exchangers, which is an improvement on a common flat-plate radiating fin and a crevasse radiating fin. The high-efficient strengthened anti-vibration radiating fin is provided with a substrate, and the substrate is provided with a plurality of tube holes. The radiating fin is characterized in that pluralities of spherical bosses are punched on the substrate. The substrate is in the shape of a flat plate and has a function of strengthening heat exchange area, the anti-vibration spherical bosses punched on the substrate have functions of interfering fluid vibration and preventing the radiating fin vibrating, and further, the anti-vibration spherical bosses have a turbulence function for fluid, thereby increasing heat transmission coefficient. The high-efficient strengthened anti-vibration radiating fin is mainly applied to liquid heat exchangers and gas heat exchangers with high property requirements in industries such as petrochemicals, ships, metallurgy, naval vessels, electric power and the like.

Description

The efficient anti-vibration fin of strengthening

(1) technical field: the utility model relates to machinery manufacturing technology field, is a kind of efficient reinforcement anti-vibration fin that is used for heat exchanger.

(2) background technology: the efficient reinforcement cooling element overwhelming majority who makes all kinds of heat exchangers now rolls garden ring rib structure outward for the light pipe, and also some is light pipe overcoat plate radiating plate, annular cut fin or corrugate fin structure.Cooling medium in the existing structure only depends on garden ring fin or plate radiating plate enhanced heat exchange area with the medium that is cooled.The heat exchange area that garden ring fin is strengthened under unit volume appearance and size is less, though the heat exchange area that plate radiating plate is strengthened under unit volume appearance and size is bigger, plate radiating plate does not have the flow-disturbing effect to medium, and heat transfer coefficient is less.Though other has a kind of cut fin and corrugate fin that medium is had the flow-disturbing effect, but perishable the coming off of cut place fin, the corrugate fin medium must produce vibration when flowing betwixt, fin is destroyed to come off, if the fin that comes off enters the damage that will cause equipment behind the miscellaneous equipment, serious will cause equipment burnout.

(3) summary of the invention: the purpose of this utility model will solve existing plate radiating plate does not exactly have the flow-disturbing effect to medium, the heat transfer coefficient problem of smaller, can not satisfy the problem of high heat-transfer performance, high reliability request, a kind of efficient reinforcement anti-vibration fin is provided.

Concrete scheme of the present utility model is: improve at plate radiating plate, it has flat plate substrate, has some pores on the substrate, it is characterized in that: be shaped on some antivibration sphere boss in the substrate upper punch.

The radius of a ball of the boss of sphere described in the utility model is 2-4mm.

The radius of a ball at on-chip all sphere boss in the utility model can be consistent, also can be inconsistent.

Flat plate substrate of the present utility model has been strengthened heat exchange area; Some sphere boss of punching out on substrate have the effect of interfering fluid oscillation, preventing the fin vibration; And antivibration sphere boss convection cell has the effect of flow-disturbing, thereby has improved heat transfer coefficient.Be used for heat exchanger and can improve heat transfer coefficient, heat exchange efficiency and service life.

(4) description of drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a left view of the present utility model;

Fig. 3 is the zoomed-in view of the A-A among Fig. 1.

Among the figure: 1-copper sheet or aluminium flake, 2-pore, 3-sphere boss.

(5) specific embodiment:

Referring to Fig. 1,2,3, the utility model adopts copper sheet 1 (or aluminium flake) (length and width need be determined by the arrangement space of heat exchanger) to make substrate, the some pores 2 of punching out (determining the position and the quantity in hole according to the layout of heat exchanger tube) on copper sheet 1, particularly go back punching out on the copper sheet in the utility model 1 a plurality of antivibration sphere boss 3 are arranged, the size Control of all sphere boss 3 is in radius of a ball R is the 2-4mm scope, the radius of a ball at same on-chip sphere boss 3 can be consistent, but the sphere boss that is preferably the different radiuses of a ball carries out irregular distribution.

Claims (3)

1. the efficient anti-vibration fin of strengthening has flat plate substrate, has some pores on the substrate, it is characterized in that: be shaped on some antivibration sphere boss in the substrate upper punch.

2. a kind of efficient reinforcement anti-vibration fin according to claim 1, it is characterized in that: the radius of a ball of described sphere boss is 2-4mm.

3. a kind of efficient reinforcement anti-vibration fin according to claim 1 and 2 is characterized in that: the radius of a ball of on-chip all sphere boss can be consistent, also can be inconsistent.
