Abstract

The invention discloses an unpowered air cooler which is characterized by comprising an air cylinder and a tube bundle. The air cylinder and the tube bundle are placed on a framework. An unpowered fan can be arranged at the upper end of the air cylinder, and the lower end of the air cylinder is an air inlet and provided with an air inlet adjusting device. Air flowing is not forcefully driven by operation of the fan, and air flowing and tube bundle heat exchange are driven by only strengthening air natural transpiration by the temperature difference, unpowered heat exchange is achieved, and the purposes of cooling, condensing and heating process media in a pipeline of a tube bundle are achieved. In addition, air flow is large, the heat exchange effect is good, the structure is simple, and the unpowered air cooler is convenient to use and capable of reducing electricity consumption.

Description

Non-power air cooler

Technical field:

The present invention relates to a kind of air cooler, be specifically related to a kind of unpowered air cooler.

Background technology:

Along with the fast development of Chinese national economy, energy resource consumption constantly increases, an energy-saving and cost-reducing important process that has become China " 12 " plan.And air cooler as fluid condensation, cooling, heating visual plant, its annual power consumption is very huge.If can reduce its power consumption, will play important effect to saving energy and reduce the cost.

When air cooler moves, often can see such situation: after fan for air cooler shuts down, still can guarantee segment fluid flow cooling, the machine that even do not blow in certain areas, the north in winter only depends on natural convection air effect just can meet the cooling requirement of fluid.

Summary of the invention:

The object of the present invention is to provide a kind of good effect of heat exchange and controlled unpowered air cooler.

The object of the present invention is achieved like this, and unpowered air cooler, is characterized in that: comprise air duct and tube bank and be arranged on framework, described air duct lower end is air inlet and is provided with air intake adjusting device.

In order further to control air quantity, on above-mentioned air duct, be also provided with air door.

Above-mentioned air door is rotary air door or slidingtype air door.

In order further to improve air cooling effect, above-mentioned air duct upper end is provided with no-power air blower.

Above-mentioned tube bank is arranged in described air duct.

Above-mentioned tube bank also can be arranged between above-mentioned air duct and above-mentioned air intake adjusting device.

Above-mentioned tube bank is finned-tube bundle, comprises base tube and is arranged on the fin outside base tube, and the upper end of described base tube is medium inlet port, and lower end is media outlet.

Above-mentioned air intake adjusting device is slidingtype or rotary, can move up and down, regulates air quantity.

Above-mentioned air duct be shaped as polygon, circle, ellipse, taper or hyperbola.

Above-mentioned polygon comprise rectangle, square, trapezoidal and parallelogram,

When high-temperature technology MEDIA FLOW is during through above-mentioned unpowered air cooler, restrain outside high-temperature hot air and external environment cold air and form larger temperature difference, air themperature skewness produces density gradient, under the density gradient of air and gravity synergy, produce buoyancy lift upwards, and then cause the free convection of air, heat exchange is carried out in the tube bank of flowing through, and regulate air quantity by being arranged on the air door at air duct middle part, reach control medium outlet temperature, air flows to atmospheric environment from the sucking-off of air duct top subsequently.

The present invention has following beneficial effect:

1, the present invention does not force drive Air Flow by blower fan running, only depends on strengthening air natural transpiration to drive Air Flow and tube bank heat exchange, has realized unpowered heat exchange, can reach the object of processing medium in cooling, condensation or heating tube bundle pipeline.

2, the present invention adopts the swollen head of hydraulic drive to increase tube bank base tube external diameter, makes fin and tube bank base tube interference fit, has reduced thermal contact resistance, has improved heat transfer efficiency; Adopt the not equidistant finned-tube bundle of 2-15mm can reduce air drag, increased rate of air circulation.

3, the present invention adopts automatic or manual to control air intake adjusting device, air door, makes the air quantity can be controlled, can avoid cooling medium to occur cold or overheated phenomenon.

4, the applicable difform air duct of the present invention, can require to choose the air duct form that cost performance is the highest according to difference.

5, the present invention is simple in structure, and air flow effect is good, and heat exchange efficiency is high, saves power consumption.
