Abstract

The utility model relates to a steel and aluminium combined radiator. The utility model is characterized in that the utility model is composed of a steel water pipe and aluminium radiating fins which can be penetrated through the steel water pipe, and the steel water pipe and the aluminium radiating fins can be pressed and combined together. The utility model has the advantages of simple structure, reasonable structure, low product price, good heat-conducting performance, high heat efficiency, beautiful appearance, strong corrosion resistance performance and long service life, and not only has all the advantages of the existing aluminium alloy radiator but also has the cost which is equivalent to the existing cast iron column type radiator.

Description

The combined radiator of steel aluminium

The utility model relates to a kind of radiator, relates in particular to the combined radiator of a kind of steel aluminium.

Traditional radiator has varied, more typically have: column type cost iron, the cast iron circle wing, steel column type, steel serial finned type, steel flat-tube type, occurred aluminium alloy radiator in recent years again, because aluminium alloy radiator has in light weightly, volume is little, good heat dissipation effect, simple in structure in addition, aesthetic in appearance again, surperficial corrosion resistance is strong, therefore, it is once the favor of building industry occurring being subjected to.But 1., the price of aluminium alloy exceeds 6～7 times than steel, and is higher 9～10 times than cast iron, because its price reasons has influenced applying of it to a certain extent, though this aluminium alloy radiator possesses above-mentioned advantage, also have the following disadvantages:.2., the intensity of aluminium is more much lower than the intensity of steel, during use, if will make aluminium alloy reach the compressive resistance equal with steel part, its wall thickness must strengthen, and so also makes the cost increase of aluminium alloy radiator.3., in pure soft water, there is good corrosion resistance the aluminium and the steel capital, but when containing impurity in the water, because the metal activity of aluminium is stronger than steel, the corrosion resistance of aluminium sharply descends, shortened dramatically the service life of aluminium alloy radiator, and present already used aluminium alloy radiator has proved this point.4. the welding performance of aluminium is more very different than steel, the welding equipment complexity of aluminium, and high to operator's technical merit requirement, welding quality often is difficult to guarantee that this seems particularly outstanding in batch process, also increased the cost of product to a certain extent.

The combined radiator of a kind of steel aluminium that the purpose of this utility model designs at existing problem in the above-mentioned prior art just, this heating sheet structure advantages of simple, product price is cheap, good heat conductivity, thermal efficiency height, decay resistance is strong, long service life.

The purpose of this utility model realizes by following measure: the combined radiator of this steel aluminium is made up of steel water pipelines and the aluminum thermal fin that is installed on the steel water pipelines.

In the utility model, steel water pipelines and aluminum thermal fin are bound up by being press-fitted; The both sides of radiator are provided with steel side plate and end cap; Each sheet aluminum thermal fin both sides respectively is provided with the heat radiation wing, all forms two row's heat radiation wings after fin penetrates piecewise, and heat radiation is even, and the people is scalded.

The advantage that the utility model is compared with prior art possessed is: 1., since the water route adopted steel pipe, thereby guaranteed to have operating pressure and the service life that is equal to trunk line, guaranteed the security reliability of radiator work.2., adopt steel aluminium combining structure, saved aluminium, reduced material cost.3., since steel have good welding performance, reduced welding cost, and guaranteed welding quality.4., radiating element adopts aluminum alloy materials, therefore possessed all advantages of existing aluminium alloy radiator: good heat conductivity, thermal efficiency height, aesthetic in appearance generous.5., because aluminium alloy shape material is drawn into the planform of various complexity easily, be convenient to enlarge area of dissipation, forms good cross-ventilation, make it under limited volume, obtain the heat dissipation capacity of maximum.6., under the condition of equal heat dissipation capacity, adopt the radiator of this structure fabrication, therefore its cost, has extensive market prospects with column type cost iron radiator cost is suitable at present.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the structural representation of another embodiment of the utility model.

The utility model is explained in detail below in conjunction with accompanying drawing:

As shown in Figure 1, 2: the combined radiator of this steel aluminium is by steel water pipelines (1) and be installed on the aluminum thermal fin (2) that its both sides on the steel water pipelines respectively are provided with heat radiation wing (5) and form, and steel water pipelines and aluminum thermal fin are bound up by press-fiting to be inserted in; The both sides of radiator are provided with steel side plate (3) and end cap (4), and to guarantee its intensity, end cap (4) locates to be provided with vent valve (6).All adopt welding manner to be connected between steel side plate (3) and steel water pipelines (1) and the steel end cap (4), all form two row's heat radiation wings after fin penetrates piecewise, heat radiation evenly and can not make the people scald.When using, hot water or hot gas steel water pipelines one end enter radiator, are flowed out by the other end behind end cap, and the aluminum alloy heat sink that is sleeved on the water pipe absorbs heat from pipeline, and outwards dispels the heat by the fin on the fin.

Fig. 3 is the topology view of another embodiment, and its difference is: the steel thermal conductive water pipe repeats bending, and fin can divide two-layer installing up and down, and heat conduction amount is bigger, and its working method is with last identical.
