Abstract

A material-saving and energy-saving multipurpose waved radiating fin is made of a common sheet steel, is not changed in the appearance size, and is provided with peripheral raised grains calendered by a special die, so as to form a structure with a thicker inside and thinner outside and with the thickness difference of 40%-60%, as a result, the superficial area is enlarged for 40%-60%, the technical requirements for cold and hot air convection are met. The material-saving and energy-saving multipurpose waved radiating fin can be used for producing products for cold and hot exchange, so that the manufacturing cost and use cost are lowered, and the requirements for energy conservation and emission reduction are satisfied.

Description

Saving metal material and energy multipurpose wave shaped radiator

One, technical field;

The utility model relates to cold and hot switching equipment.

Two, background technology

At present: the fin on the cold and hot switching equipment (fin), basically all adopted the enwinding type manufacturing process aspect manufacturing and designing.At the cold and hot switching equipment that industrial circle is made with this kind technology, cold and hot switching performance is poor, and heat is difficult for being conducted, and the cycle-index that only adds big flood solves the problem that heat distributes.Wasted electric energy, caused waste the service life of also having reduced water pump simultaneously, enterprise also is at a complete loss as to what to do to this.Especially the various heating radiators made from it exist poor performance, heat radiation slowly too, cause inner temperature of room situation not up to standard.In order to increase heat dissipation capacity, improve inner temperature of room, have only the radiating fin of increasing quantity to improve inner temperature of room, (how many fins has determined inner temperature of room under equal water temperature) thus much just wasted great deal of steel, electric energy to country for one.The Ministry of Construction of National Development and Reform Committee has just issued enwinding type heating equipment and has forbidden getting into civilian heating field as far back as 2004.

Current domestic civilian fin, statistics year 1000000000 of the demands of State Statistics Bureau 2008, by every heavy 3Kg, 3,000,000 tons of year demand steel as producing every square metre of materials 0.9kg with present technique, just can be saved more than 200 ten thousand tons of steel for one at this point.As adding industrial circle this part, the steel that can save every year are surprising.Also be outstanding contributions to national energy-saving and emission-reduction aspect like this.

Three, summary of the invention

For the disadvantage that the various cold and hot trade-to product that solves existing enwinding type manufacturing exists, get off the steel saving, lower manufacturing cost; Lower use cost; Lower civilian heating fee, let air pollution improve, let people that a healthy living space is arranged; This new technology provides a kind of saving metal material and energy to reduce the saving metal material and energy multipurpose undaform fin that discharging significantly improves cold and hot exchange velocity.

Saving metal material and energy multipurpose wave shaped radiator:

1. it can be used to make nearly all big-and-middle-sized cold and hot trade-to product.

2. this heat sinking sheet is not increasing materials, under the constant situation of apparent size, it lean on particular manufacturing craft around roll waviness, make its cooling surface area increase 40%-60% and do not wait.

3. wave shaped radiator, in the apparent size no change forms under the effect of mould thick outside thin difference be 40%-60%, met cooling and heat radiation requirement.

4. when the fin center was around calendering, the center can be drawn simultaneously according to product demand and stretched out the firm circle of heat conduction, has guaranteed one-time formed precision.

The data of the metal temperature value of current all cold and hot switching equipment are distinguished as follows: (operation technique is equal under the situation)

Cast iron is between 0.23-0.3W

Steel is between 0.6-0.95W

Aluminum is between 1.2-2.6W

Copper is between 1.3-2.8W

The steel new technology is between 1.266-1.45

To be building energy conservation inspection center of Harbin Institute of Technology on July 11st, 2010 detect the data of this new technology number does.

Amount is recognized (deceiving) word (R0418) number

(2010) inspection (H) (022) number

Can consult (computer) at the big inspection center of worker database

The technical scheme that this new technology adopts:

Saving metal material and energy multipurpose wave shaped radiator is by sheet metal, and thickness is produced various particular manufacturing crafts according to the specification requirement of cold and hot trade-to product, and fin all adopts mould to process with cold working mode.

The beneficial effect of this new technology: a kind of saving metal material and energy multipurpose wave shaped radiator is provided to people; This kind fin can be made various cold and hot trade-to products; Make simple, cost is low, material-saving, energy-conservation, cooling is fast, heat dissipation capacity is big, reduces lot of advantages such as air pollution.

Five, the specific embodiment:

1. select materials by the specification requirement of cold and hot trade-to product and heat radiation product.

2. load onto particular manufacturing craft to the materials of choosing with common punch press (selecting for use) excessively and make Fig. 1 according to the fin thickness.

3. load onto the calendering mould with common punch press (selecting for use), put into Fig. 1 and make Fig. 2 according to the fin thickness.

4. be contained in common punch press (selecting for use) that special-purpose hemming die is produced Fig. 3 or Fig. 4 gets final product according to the fin thickness.

In specification requirement, process required various products according to required product.

Claims (1)

1. a saving metal material and energy multipurpose fin is processed with sheet metal, it is characterized in that: wave shaped radiator around using particular manufacturing craft to roll to become, make in it thick outer thinly, and difference is 40%-60%, makes the long-pending 40%-60% of increase of its unfolded surface.
