Abstract
The utility model discloses an inner-finned double-layer heat-dissipation aluminum tube for a hot water boiler. The inner-finned double-layer heat-dissipation aluminum tube is formed by tension-compression combination of an outer-layer aluminum alloy tube (3) and a squeezed outer fin (2) of an inner-layer aluminum alloy tube (1). The squeezed outer fin (2) of the inner-layer aluminum alloy tube (1) takes the shape of a slice and is squeezed and extends out from the radial direction of the aluminum alloy tube (1). The inner-finned double-layer heat-dissipation aluminum tube is used for the hot water boiler, and multiple-layer aluminum tubes are arranged in the boiler. Hot smoke is at the outer part of the aluminum tubes to heat water in the aluminum tubes, and hot water is conveyed out. The combined heat-dissipation double-layer aluminum tubes can increase the heat-dissipation area of the aluminum tubes, the heat exchange effect is significantly increased, the surface temperature of the outer-layer aluminum tube is reduced, the heat efficiency is increased, and the service life of the aluminum tube is prolonged.
Description
Technical field
The utility model relates to boiler class technical field, more specifically to a kind of double-deck heat radiation of interior wing aluminum pipe for hot-water boiler.
Background technology
Hot-water boiler is mainly used in central heating and supplying hot water.Present hot-water boiler is mainly two kinds, iron, aluminium, and what namely the aluminum pot furnace interior used is aluminum pipe, and what the iron pan furnace interior used is iron pipe, with aluminum pipe or the heating of the water in iron pipe of Hot Water Boiler Internal, and output hot water, fuel is generally the fuel such as diesel oil, coal, living beings.
At present, in the aluminum pot stove, aluminum pipe because heat-transfer effect is good, is difficult for getting rusty, the aluminum pot stove is widely used in hot-water boiler, what aluminum pot furnace interior aluminum pipe used is all circular light pipe, simple in structure, easy to make, has the good characteristic of general aluminum pipe heat-transfer effect, but there is the lower problem of heat conduction utilization ratio in hot-water boiler, and causes that thus the aluminum pipe temperature in boiler is higher, and aluminum pipe is partially short service life, therefore, the thermal efficiency and the service life of raising hot-water boiler are the problems that the researcher need to solve.
Summary of the invention
The purpose of this utility model is in order to overcome the defective of prior art, a kind of double-deck heat radiation of interior wing aluminum pipe for hot-water boiler is provided, it is by outer field cold drawn seamless anti-aluminium-alloy pipe, the extruding aluminium alloy external finned tube of internal layer is combined into double-deck aluminum pipe by empty tension and compression, increases the area of dissipation of aluminum pipe, obviously improve heat transfer effect, improve the thermal efficiency, reduced outer aluminum tube surfaces temperature, improved aluminum pipe service life.
The technical solution adopted in the utility model: a kind of double-deck heat radiation of interior wing aluminum pipe for hot-water boiler is mainly that the inner face of outer aluminium-alloy pipe and the outer fin tension and compression of extruding of unlined aluminium compo pipe are combined into the double-deck heat radiation of interior wing aluminum pipe.
Further technical scheme is on the technique scheme basis:
And the outer fin of the extruding of described unlined aluminium compo pipe is laminar, stretches out from unlined aluminium compo pipe radial compression, is at least more than two or two.
And described outer aluminium-alloy pipe is seamless Al-alloy pipe, adopts the rustproof aluminum alloy material.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, 2, 3, a kind of double-deck heat radiation of interior wing aluminum pipe for hot-water boiler, hot-water boiler is the aluminum pot stove, hot-water boiler is welded by two-layer aluminium sheet, whole cylindrical, the boiler internal layer is four layers of aluminum pipe, and boiler bottom is established the combustion chamber, boiler below bottom aluminum pipe is provided with water inlet, boiler top top layer aluminum pipe is provided with delivery port, and hot cigarette rises, and hot cigarette is outside at aluminum pipe, water flows in aluminum pipe, boiler is the water in the heating aluminum pipe, and exports hot water by delivery port, and boiler aluminum pipe heat-transfer effect is good, be difficult for getting rusty, corrosion-resistant, good pressure-resistant performance.
The double-deck aluminum pipe of the assembling radiating of hot-water boiler, skin is seamless Al-alloy pipe (3), and seamless Al-alloy pipe (3) is by cold drawn seamless rust-preventing aluminum alloy pipe, and internal layer is that aluminium-alloy pipe (1) is by squeezing out outer fin (2).
The outer fin (2) of the extruding of seamless Al-alloy pipe (3) inner face and aluminium-alloy pipe (1) is combined integrated by tension and compression, the outer fin (2) of the extruding of aluminium-alloy pipe (1) is laminar, stretch out from aluminium-alloy pipe (1) radial compression, push outer fin (2) and be at least more than two or two, seamless Al-alloy pipe (3) adopts the rustproof aluminum alloy material.
Claims (3)
1. the double-deck heat radiation of interior wing aluminum pipe that is used for hot-water boiler, it is characterized in that: outer fin (2) tension and compression of the extruding of the inner face of outer aluminium-alloy pipe (3) and unlined aluminium compo pipe (1) are combined into the double-deck heat radiation of interior wing aluminum pipe.
2. a kind of double-deck heat radiation of interior wing aluminum pipe for hot-water boiler according to claim 1, it is characterized in that: the outer fin (2) of the extruding of described unlined aluminium compo pipe (1) is for laminar, stretch out from unlined aluminium compo pipe (1) radial compression, be at least more than two or two.
