Abstract

A high efficiency corrosion resistant radiator uses a double pipe wall structure. The internal pipe is a pipe (1) with good corrosion resistance and heat radiating performance, while the external pipe is made of aluminum (2) after melt casting and molding. The material of the internal pipes includes copper pipes, brass pipes, stainless steel pipes, low carbon steel pipes, and galvanizing pipes. The utility model not only has high heat radiating efficiency, low water-holding capacity, good pressure bearing performance, light weight, and beautiful exterior, but also solves the problem of corrosion prevention, and is particularly suitable for the condition with bad heating water quality, and high pH value.

Description

The efficient corrosion-proof radiator

The utility model relates to a kind of heat exchanger, especially heating efficient corrosion-proof radiator.

There are following characteristics in the radiator that uses now: (1) cast-iron radiator: corrosion stability is good, poor thermal conductivity, and heat exchange efficiency is low, and pressure-bearing is low, and water capacity is big, and heaviness is ornamental poor.(2) steel radiator: water capacity is little, and corrosion resistance is poor, poor thermal conductivity.(3) aluminium section bar radiator: thermal conductivity is good, light weight, but corrosion resistance is very poor.(4) simple pack alloy radiator: thermal conductivity is good, and is attractive in appearance, and corrosion resistance is relatively poor.Because there is such or such deficiency in existing radiator, cause China's unit are heating energy consumption be developed country 2-3 doubly.Wherein Yi Bufen reason is owing to adopting traditional heat-dissipating device inefficiency to cause.Because China's heat supply water quality situation complexity, the higher new-type radiator corrosion resistance of the thermal efficiency is poor, has hindered the update of old-fashioned radiator.

The purpose of this utility model is: propose a kind of heating radiator, overcome the deficiency of existing radiator, prevent possible seepage, its thermal conductivity is good, light weight, and corrosion resistance is good.

The utility model is achieved through the following technical solutions: the efficient corrosion-proof radiator, it is characterized in that adopting two-tube wall construction, and inner tube is the good pipeline of anti-corrosion thermal diffusivity, skin is the aluminium of fusion cast process.

Further improvement of the utility model is: the inner tubal wall of inner tube is provided with helicla flute.

It is aluminium alloy heat radiator that the utility model can be considered to skin, is bumped into that corrosion resistance is good, thermal diffusivity is good, the tubing of band tube wall inner spiral groove.Material of pipe comprises copper tube, brass tube, stainless steel tube, low carbon steel pipe, galvanized pipe in these.

Characteristics of the present utility model are: radiating efficiency height not only, and Rong Shui is few, the pressure-bearing height, light weight, the outward appearance grace, and fundamentally solved the anticorrosion problem, special heating water quality inferiority, the situation that acid-base value is high of adapting to.Its corrosion resistance is better than traditional cast-iron radiator, its radiating efficiency height of while, and heat dispersion is superior.The utility model can be brought into play the pack alloy beautiful design on the one hand, light weight, and the advantage that thermal conductivity is good can fundamentally solve the not problem of alkali corrosion resistance of aluminium alloy on the one hand.Greatly promoted the security performance of radiator.Owing to adopt corrosion resistant material, eliminated fundamentally in the past that aluminium alloy heat radiator produces hydrogen in corrosion process, as untimely discharge, will bring very big potential safety hazard.The utility model can be realized energy savings, reduces environmental pollution, cooperates the enforcement of building energy conservation planning in 2010.

Because adopt double-walled construction, this structure is a kind of typical pressure-resistance structure, according to Mechanics Calculation, the equal wall thickness homogenous material of this structure can bear higher pressure.Higher load performance not only provides stronger flexible shape for heating design, adapts at present increasing skyscraper.And provide higher safety coefficient to radiator.Tube wall adopts advanced helicla flute wing structure, and this structure has not only increased the contact area of tube wall and heating agent, has also strengthened the turbulent flow of heat transport fluid, has improved heat exchange efficiency very significantly.

The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:

Fig. 1 is the utility model structural representation

Fig. 2 is a partial structurtes schematic diagram among Fig. 1

Fig. 3 is transversal sectional structure schematic diagram

As shown in the figure, the efficient corrosion-proof radiator adopts two-tube wall construction, inner tube is the good pipeline of anti-corrosion thermal diffusivity 1, about thickness of pipe wall 0.6-3mm, and preferred copper tube, brass tube, the radiating effect of copper tube is better, and this pipe is cast into outer 2 by aluminum or aluminum alloy in mould.The outer heatsink fins chip architecture that constitutes as shown in Figure 3, the inner tubal wall of inner tube is provided with helicla flute 3, is drawn at inwall by broaching tool, and this processing method is a common process.That makes forms by connector at pipe end 4 as the radiator of the multi-disc of Fig. 1.The inwall pipeline adopts other all not surpass scope of the present utility model as stainless steel tube, low carbon steel pipe, galvanized pipe etc.

Shown in Figure 1, the pipe end 4 of radiator is provided with thickening layer 5, and promptly structure thicker about general aluminium alloy bed thickness 2mm than intermediate conduit, because pipe end is provided with tooth line and screwed union, can guarantee the intensity of junction like this.

Shown in Figure 2, more solid and reliable for pipe end is combined with alloy matrix aluminum, internally pipe port is provided with and rolls tooth 6, and this particular structure has increased the bonded area between pipe port and the base material, has improved bond strength.
