Abstract
The utility model relates to a heat exchange tube, in particular to a pressure-point finned tube. The pressure-point finned tube is characterized by comprising a tube body (1). An outer wall of the tube body (1) is provided with spiral pitted-surface fins (2) and a plurality of dot-shaped concave pits (3). The spiral pitted-surface fins arranged on the outer wall of the pressure-point finned tube are used for increasing heat exchange area of the finned tube. Pressure points on the outer wall of the tube body enable the outer wall of the tube body to be extruded to form the spiral dot-shaped concave pits so that heat exchange effect of the finned tube is improved.
Description
Technical field
The utility model relates to a kind of heat exchanger tube, relates in particular to a kind of pressure point finned tube.
Background technology
Along with improving constantly of industry technologies such as refrigeration, metallurgy, machinery, boiler manufacturing, the requirement of heat exchanging device also improves accordingly.The performance of heat exchanger depends on the performance of heat exchanger tube to a great extent.At present, traditional mode is to adopt the bronzing pipe of good heat conductivity as heat exchanger tube, in order to strengthen its heat exchange efficiency, all is the fin that is rolled into all size height at circular tube exterior generally, thereby carries out heat conduction reinforced to this kind tube exterior.Yet when some media were conducted heat, the heat exchange efficiency of heat exchanger tube can not be guaranteed nonetheless.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of heat exchange efficiency higher pressure point finned tube.
The purpose of the utility model is achieved in that
The utility model pressure point finned tube comprises body, is processed with spiral pitted skin fin on the outer wall of said body, also is pressed with some point-like pits on the outer wall of said body.
Compared with prior art, the beneficial effect of the utility model is:
Be processed with the fin of spiral pitted skin shape on the outer wall of this pressure point finned tube, be used to increase the heat exchange area of finned tube, and on tube wall pressure point, make to be forced out spiral helicine point-like pit on the tube wall, thereby increased the heat exchange effect of finned tube.
Description of drawings
Fig. 1 is the structural representation of the utility model pressure point finned tube.
Wherein: body 1, spiral pitted skin fin 2, point-like pit 3.
The specific embodiment
Referring to Fig. 1; The utility model relates to a kind of pressure point finned tube, comprises body 1, is processed with spiral pitted skin fin 2 on the outer wall of said body 1; Said spiral pitted skin fin 2 is used to increase the heat exchange area of finned tube; Also be pressed with some point-like pits 3 on the outer wall of said body 1, said point-like pit 3 on the outer wall of body 1 in the shape of a spiral shape arrange, be used to increase the heat exchange effect of finned tube.
Claims (1)
1. pressure point finned tube, it is characterized in that: it comprises body (1), is processed with spiral pitted skin fin (2) on the outer wall of said body (1), also is pressed with some point-like pits (3) on the outer wall of said body (1).
