Abstract
The invention discloses a tubular heat exchanger with rotating fins, which comprises connecting copper pipes which are positioned on the external sides of two baffles, and finned pipes. Two ends of each finned pipe are rotatablely arranged between the baffles on the two sides through a rotary sealing joint and are connected with each connecting copper pipe through the rotary sealing joint. Each finned pipe comprises a pipe body and a plurality heat dissipation fins which are arranged along the axial direction of each pipe body in an extending mode, and are uniformly dispersed on the outer wall of each pipe body. Each rotary sealing joint comprises a through fixed pipe and a through moving pipe, wherein one end of the moving pipe is rotatablely connected with one end the fixed pipe; a rolling bearing is sleeved on a joint of the fixed pipe and the moving pipe; an outer ring of the rolling bearing is fixedly combined with the periphery surface of the fixed pipe; and an inner ring of the rolling bearing is fixedly combined with the periphery surface of the moving pipe. The finned pipes rotate under the action of a fan inside an air conditioner, eliminate an air viscous layer, and enlarge air speed of a heat exchange surface; freezing medium in each finned pipe rotates along with the finned pipe, changes a laminar flow into a turbulent flow, and eliminates the air viscous layer outside the pipe, thereby achieving better heat exchanging effect.

Summary of the invention
Technical problem to be solved by this invention is that it is movable that a kind of finned tube is provided, and has increased inner with the outside heat convection of heat exchanger, has increased the heat exchange amount greatly, has improved the pipe heat exchanger that has rotating fins of whole heat exchange efficiency.
The technical solution adopted in the present invention is: a kind of pipe heat exchanger that has rotating fins, include: the baffle plate of both sides, be positioned at the connection copper pipe in the baffle plate outside, also be provided with finned tube, the two ends of described finned tube are to can be rotatably set between two side shields by the rotatory sealing joint, and by the rotatory sealing joint be connected copper pipe and be connected.
The radiating fin that described finned tube includes body and is provided with along the axially-extending of body, described radiating fin body is provided with a plurality of, and is evenly dispersed on the outer wall of body.
Described radiating fin is integrally formed in body.
Described rotatory sealing joint includes: the fixed tube of perforation is formed with the external seal screw thread on the outer peripheral face of described fixed tube one end; The moving pipe that connects is formed with interior sealing thread on the inner peripheral surface of described moving Guan Yiduan; Described moving pipe rotatably is connected on the fixed tube by the engagement of the external seal screw thread of sealing thread in it and fixed tube; Also be provided with rolling bearing, described rolling bearing is enclosed within the junction of fixed tube and moving pipe, the outer peripheral face secure bond of the outer ring of described rolling bearing by connector and fixed tube together, the outer peripheral face secure bond of the inner ring of described rolling bearing and moving pipe is together.
That end that the fixed tube of described rotatory sealing joint does not form the external seal screw thread is fixedlyed connected with copper pipe, and the moving pipe of described rotatory sealing joint does not form the fixedly connected finned tube of that end of sealing thread.
The pipe heat exchanger that has rotating fins of the present invention, fin and body are integrally formed, under the effect of the fan of finned tube in air-conditioning, the finned tube rotation has been eliminated the air viscous layer, and has been increased the heat exchange surface wind speed, the temperature field constantly changes, and has strengthened heat convection greatly; Cold-producing medium in the finned tube is rotated together, become turbulent flow and eliminate pipe outer air viscous layer from laminar flow by making tube fluid, thereby reach heat exchange effect preferably.
