Description
The present invention relates to a method for manufacturing a heat exchanger pipe, and more particularly, to a method for manufacturing a heat exchanger pipe having improved workability and productivity by improving a method of coupling a ring-type heat dissipation fin to an outer circumferential surface of a copper pipe.
In general, the heat exchange pipe is used for a heat exchanger such as an oil cooler and the like, and a heat dissipation fin is usually coupled to the outer circumferential surface of the copper pipe.
Korean Utility Model Registration No. 266582 discloses a structure of a conventional heat exchange pipe. 4 and 5 of the patent, a heat exchange pipe was manufactured by winding a heat dissipation fin when a heat dissipation fin is coupled to an outer circumferential surface of a copper pipe. That is, a heat exchanging pipe was manufactured by extruding a heat radiation fin for a long time and winding it in a screw method on the outer circumferential surface of the copper pipe.
However, such a conventional manufacturing method has a problem in that mass production is difficult because of poor workability. In addition, conventionally, the soldering welding to a portion to fix the heat radiating fins to the copper pipe, there is a problem that the performance of the product is not degraded due to the gap of the falling portion when the solder is incorrectly dropped or dropped to corrosion.
The present invention has been proposed to improve the above problems, the object of which is to improve the workability and production by improving the joining method to easily and firmly combine the ring-type heat radiation fins on the outer peripheral surface of the copper pipe without soldering It is to provide a method of manufacturing a pipe.
The object described above is configured to maintain a constant distance through the space portion when the copper pipe formed inside the hollow, and has a ring shape to be fitted to the outer circumferential surface of the copper pipe and the space portion is integrally formed on one surface and inserted into the copper pipe. Providing a heat dissipation fin made of aluminum; Assembling a plurality of heat dissipation fins sequentially on an outer circumferential surface of the copper pipe; Holding both ends of the copper pipe through a jig to hold a plurality of heat radiation fins so as not to flow; And expanding the diameter of the copper pipe while passing through the inside of the copper pipe so that the heat dissipation fin is firmly fixed to the outer circumferential surface of the copper pipe. It is achieved by a method for producing a heat exchange pipe.
And the heat radiation fin is formed to be bent inwardly in the middle portion of the space portion to minimize the friction when fitted to the copper pipe, and when the diameter of the copper pipe is expanded in the state fitted to the copper pipe to be in close contact with the outer diameter of the copper pipe It is characterized in that the heat dissipation fins located at the front and back while being unfolded to be perfectly in contact without gaps.
The object described above is configured to maintain a constant distance through the space portion when the copper pipe formed inside the hollow, and has a ring shape to be fitted to the outer circumferential surface of the copper pipe and the space portion is integrally formed on one surface and inserted into the copper pipe. Providing a heat dissipation fin made of aluminum; Inserting a diameter expansion hole having a diameter larger than an inner diameter of the copper pipe to a portion of one end of the copper pipe to expand the diameter of the copper pipe; Inserting a plurality of heat dissipation fins sequentially from opposite ends of the copper pipes so that the plurality of heat dissipation fins are assembled in a state of being caught in an extended portion of the copper pipe; Pressurizing the heat dissipation fins such that the plurality of heat dissipation fins assembled to the copper pipes do not flow in close contact with the extended ends of the copper pipes; And extending the diameter of the copper pipe by allowing the diameter expansion port to pass through the inside of the copper pipe to securely radiate the heat dissipation fins to the outer circumferential surface of the copper pipe. Is achieved by
When the heat exchange pipe is manufactured through the manufacturing method of the heat exchange pipe according to the present invention, the ring type heat dissipation fin can be easily and firmly coupled to the outer circumferential surface of the copper pipe without soldering, thereby improving workability and allowing mass production. As in the prior art, there is an effect that the problem of deterioration in product performance due to poor soldering state or corrosion is not caused.
