Abstract
The invention relates to a finned tube for a heat exchanger. The finned tube is characterized by comprising a copper tube (1), wherein the copper tube (1) is made of red copper or brass or white copper; a spiral groove (2) is formed in the outer wall of the copper tube (1); and an aluminum fin (3) is arranged in the spiral groove (2), and is higher than the copper tube (1). The spiral groove is arranged in the outer wall of the finned tube for the heat exchanger, and the aluminum fin with strong resistance to high temperature is arranged in the spiral groove, so that the heat exchange efficiency of the copper finned tube can be improved; and the aluminum fin is higher than the copper tube, so that the heat exchange area is increased, and the heat exchange efficiency of the heat exchange tube can be further improved.
Description
Technical field
The present invention relates to a kind of heat exchanger tube, particularly relate to a kind of heat exchanger finned tube.
Background technology
Heat exchanger tube is one of element of heat exchanger, is placed within cylindrical shell, and for the exchange of heat between two media, along with improving constantly of the industry technology such as refrigeration, metallurgy, machinery, boiler manfacturing, the requirement of heat exchanger also improves accordingly.The performance of heat exchanger depends on the performance of heat exchanger tube to a great extent.At present, traditional mode adopts the bronzing pipe of good heat conductivity as heat exchanger tube, but when conducting heat to some media, the heat exchange efficiency of heat exchanger tube can not be guaranteed.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, the heat exchanger finned tube that a kind of heat exchange efficiency is higher is provided.
The object of the present invention is achieved like this:
Heat exchanger finned tube of the present invention, comprises copper pipe, and the outer wall of described copper pipe offers helical groove, is provided with aluminum fin-stock in described helical groove.
The height of described aluminum fin-stock is higher than copper pipe.
Described copper pipe is red copper or brass or copper-nickel alloy.
Compared with prior art, the invention has the beneficial effects as follows:
The outer wall of this heat exchanger finned tube is processed with helical groove, aluminum fin-stock is provided with in helical groove, the resistance to elevated temperatures of this aluminum fin-stock is stronger, the heat exchange efficiency of copper fin pipe can be improved, and the height of aluminum fin-stock is higher than copper pipe, thus add heat exchange area, the heat exchange efficiency of heat exchanger tube can be further increased.
Accompanying drawing explanation
Fig. 1 is the structural representation of heat exchanger finned tube of the present invention.
Wherein: copper pipe 1, helical groove 2, aluminum fin-stock 3.
Detailed description of the invention
See Fig. 1, the present invention relates to a kind of heat exchanger finned tube, comprise copper pipe 1, described copper pipe 1 can be red copper, brass, copper-nickel alloy etc., the outer wall of described copper pipe 1 offers helical groove 2, aluminum fin-stock 3 is provided with in described helical groove 2, the resistance to elevated temperatures of described aluminum fin-stock 3 is comparatively strong, can improve the heat exchange efficiency of copper fin pipe, and the height of aluminum fin-stock 3 is higher than copper pipe 1, thus add heat exchange area, the heat exchange efficiency of heat exchanger tube can be further increased.
Claims (3)
1. a heat exchanger finned tube, is characterized in that: it comprises copper pipe (1), the outer wall of described copper pipe (1) offers helical groove (2), is provided with aluminum fin-stock (3) in described helical groove (2).
2. a kind of efficient heat-exchanging pipe according to claim 1, is characterized in that: the height of described aluminum fin-stock (3) is higher than copper pipe (1).
3. a kind of efficient heat-exchanging pipe according to claim 1, is characterized in that: described copper pipe (1) is red copper or brass or copper-nickel alloy.
