Disclosure of Invention

The utility model aims at providing a heat transfer fin for titanium pipe cooler to above-mentioned condition, this heat transfer fin structural improvement is simple novel, and heat transfer performance obtains great promotion.

The utility model has the following concrete scheme: a heat exchange fin for a titanium tube cooler is provided with a fin body, wherein a plurality of heat exchange tube holes for inserting heat exchange tubes are arranged in rows on the fin body, a bridge-shaped crevasse is arranged between two transversely adjacent heat exchange tube holes, an annular crevasse is arranged around each heat exchange tube hole, and the annular crevasse is formed by annularly and uniformly distributing four fan-shaped crevasses around the corresponding heat exchange tube holes; the upper end edge and the lower end edge of the fin body are arranged to be of a sawtooth corrugated structure.

Further, the utility model discloses be transversely staggered between the adjacent heat transfer tube hole about well and arrange.

Furthermore, in the present invention, the shape of the bridge-shaped crevasse is rectangular.

Further, the utility model discloses in every fan-shaped crevasse all set up on the horizontal, vertical 45 angular bisectors between with corresponding heat transfer tube hole centre of a circle as the center.

The utility model discloses a to current radiating fin's institutional advancement design, effectively promoted the radiating fin's that is applied to on the titanium pipe cooler heat transfer performance, increased radiating fin's marginal rigidity simultaneously, had fine in-service use and worth.

Drawings

Fig. 1 is a schematic diagram of the overall structure of the present invention.

In the figure: 1-fan-shaped crevasse, 2-sawtooth-shaped corrugated structure, 3-heat exchange tube hole, 4-bridge-shaped crevasse and 5-fin body.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
