Abstract
The utility model relates to a heat-exchanging device, in particular to a metal recuperator tube which comprises a tube body and fins which enwind outside the tube body in a helical way. The fins and the tube body form an integral structure; corrugated heaves are arranged on the tube body; the proportion range between the thickness of the tube body and the height of the corrugated heaves is 3 to 6:1, the optimal height proportion between the thickness of the tube body and the corrugated heaves is 3.8:1; the corrugated heaves take the shape of a helix, and accord with the thread pitch and the helix angle of the fins. The heat-exchanging device has the advantages that the hardness is high, the reliability is strong, the manufacturing cost is low, the thermal contact resistance is lower, the heat transfer efficiency is higher, no thermal contact resistance exists, the heat shock resistance, the mechanical shock resistance and the thermal expansion property are good, the hardness of the tube body is good, the rigidity is strong, and the shock resistance is good.
Description
Technical field
The utility model relates to a kind of heat-exchange device, especially a kind of metal heat exchanger tube.
Background technology
In the prior art, the shell-and-tube heat exchanger of prolonged application, the heat exchanger tube wall thickness, inner wall smooth, heat transfer coefficient is low, easily fouling.Though plate type heat exchanger heat transfer coefficient height, also easily fouling is stopped up, and limited by seal, and non-refractory, high pressure easily leak.Occur corrugated tube heat exchanger in recent years, used the ripple enhanced heat exchange, received effect preferably.But ripple is overstocked, and wave height is too high, and is not good enough to the combined influence of heat transfer and flow resistance, has deficiencies such as heat transfer coefficient is low, the heat exchange resultant effect is not good enough.
Summary of the invention
The purpose of this utility model is in order to provide a kind of heat transfer coefficient higher finned metal heat exchanger tube.
For realizing the purpose of this utility model, this specification provides a kind of metal heat exchanger tube, comprises body and the external fin of helical form winding pipe, and fin and body are structure as a whole, and body is provided with the ripple projection.The body wall thickness is 3 to 6 to 1 with the proportion of ripple height of projection, and the ratio of its optimum height is 3.8 to 1.The ripple projection is a screw type, and its pitch, lead angle with fin is consistent.
This heat exchanger tube of the utility model has the intensity height, good reliability, and low cost of manufacture, thermal contact resistance is lower, heat transfer efficiency is higher, contactless thermal resistance, heat-resisting shake and mechanical shock, hot expansibility is good, the characteristics that body intensity is good, rigidity is strong, shock resistance is good.
The purpose of this utility model, feature and advantage will be in conjunction with the embodiments, are further described with reference to accompanying drawing.
Description of drawings
Fig. 1 is a kind of structural representation profile of the present utility model;
Among the figure: 1 is body, and 2 is fin, and 3 is the ripple projection.
The specific embodiment
With reference to last figure, provide following embodiment.To help to understand the utility model by embodiment, but not limit content of the present utility model.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
Embodiment 1: this metal heat exchanger tube, comprise the fin 2 that body 1 and helical form winding pipe are external, and fin 2 is structure as a whole with body 1, and body 1 is provided with ripple projection 3.The ratio of body 1 wall thickness and ripple projection 3 height is 3: 1.Ripple projection 3 is a screw type, and its pitch, lead angle with fin 2 is consistent.
Embodiment 2: the ratio of embodiment 1 described metal heat exchanger tube body 1 wall thickness and ripple projection 3 height is 3.8: 1.
Embodiment 2: the ratio of embodiment 1 described metal heat exchanger tube body 1 wall thickness and ripple projection 3 height 6: 1.
