Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown, a composite tube for a heat exchanger includes a metal outer sleeve 1 made of heat-conducting and corrosion-resistant materials. The metal outer sleeve 1 is eccentrically set with a metal inner sleeve 2, corresponding to the outer wall of the metal inner sleeve 2. The margin cavity 3 between 201 and the inner wall 101 of the metal outer sleeve 1 is tightly embedded with a crescent-shaped expansion heat-conducting flat tube 4, one side of the expansion-tight heat conduction flat tube 4 is close to the outer wall 201 of the metal inner sleeve 2, and the metal The inner casing 2 and the expanded heat-conducting flat tube 4 are respectively in close contact with the inner wall 101 of the metal outer sleeve 1 , and the inner cavity 401 of the expanded-expanded heat-conducting flat tube 4 is filled with heat-conducting materi...

Abstract

The invention relates to a composite tube for a heat exchanger. The composite tube comprises an outer metal sleeve made of a heat-conducting and corrosion-resistant material, wherein an inner metal sleeve is eccentrically sleeved in the outer metal sleeve; a flat tensioning and heat-conducting tube is correspondingly embedded in a margin cavity between the outer wall of the inner metal sleeve andthe inner wall of the outer metal sleeve; one side of the flat tensioning and heat-conducting tube is closely attached to the outer wall of the inner metal sleeve; the inner metal sleeve and the flattensioning and heat-conducting tube are closely propped against the inner wall of the outer metal sleeve respectively; and the cavity of the flat tensioning and heat-conducting tube is filled with a heat-conducting material. By using the composite tube for the heat exchanger with the structure, the outer metal sleeve is made of the corrosion-resistant material and the corrosion resistance is effectively improved so as to improve the service life of the heat exchanger.

Description

technical field [0001] The invention relates to the technical field of heat exchangers for heat pumps, in particular to a composite tube for heat exchangers with reasonable structure, good corrosion resistance and good thermal conductivity. Background technique [0002] In existing heat exchangers for heat pumps, the heat exchange tubes are mostly set in a single tube type. The working principle is to exchange heat between the fluid body and water flowing between the inside and outside of the tube. The thermal performance is good, but the outer wall of the single-tube tube is in contact with the fluid body for a long time, and the corrosion resistance is poor, which affects the service life of the heat exchanger; moreover, the heat transfer area of ​​the single-tube tube body is limited, and the heat transfer effect cannot be further improved; Or, if the fluid in the heat exchange tube leaks out into the water, it will pollute the water and damage human health. Therefore, in...
