The hot blast of box house is taken away so that the air-flow of whole box house forms a list with outside air-flow
Circulation, and then the electronic equipment of whole box house is dispelled the heat.But this single-cycle heat radiation side
There is certain drawback in formula, first, the cold wind that air outlet is sent into is usually ambient wind, due to environment wind facies
Relatively low for its temperature from the point of view of the electronic equipment of box house, therefore it is called cold wind.However as extraneous ring
The continuous rising of border temperature, the temperature of the cold wind that air outlet is sent into also raises constantly, therefore, very
The heat radiation to electronics showcase or bulletin board box house is reduced in big degree.Secondly as use single-cycle side
Formula is dispelled the heat, and therefore, outside dust and steam are easy to along with outside cold wind enters box house,
And then the electronic equipment of box house is exerted an adverse impact.Additionally, prior art is primarily upon open air
The heat radiation of electronics showcase or bulletin board, to how guaranteeing that outdoor electronic showcase or bulletin board also may be used in the environment of relatively low in temperature

If the temperature of box bottom (x=0) is t0, the temperature of casing top (x=H) is tH, it is assumed that casing
When inside is air dielectric, the unit thermal conductance of air dielectric unit mass is one in first level approximation
Constant, the most in this case, according to Thermodynamics Formulas Δ Q=Cm Δ t, can derive the temperature of box house
Degree distribution equation in air dielectric is:
Wherein: Q (x) be box house distance box bottom height be the heat shed on the point of x, λ is
The coefficient of heat conduction of air, CPBeing the specific heat of air, γ is the quality of unit air, and x is box house
The height of some distance box bottom, t is the temperature of box house point, ω0It it is air velocity.
By above-mentioned formula it is recognised that for electronics showcase or bulletin board casing, air velocity ω0It it is a pass
Bond parameter, ω0The biggest, its box house height is temperature t of x pointxStep the least, thermograde change
The least, the temperature of box house then will tend to constant.But for electronics showcase or bulletin board, air outlet
The speed of the cold wind sent into can not infinitely increase, therefore, except providing given pace by air outlet
Outside cold wind, in addition it is also necessary to electronics showcase or bulletin board box house environment is carried out certain optimization, to guarantee air outlet
The cold wind sent into is more unobstructed in box house flowing and plays a role with maximal efficiency.
Inventor proposes, and arranges heat abstractor at the rear board near electronics showcase or bulletin board casing, utilizes heat radiation
Electronics showcase or bulletin board box house is cooled down by the cold wind that the air outlet of device is sent, and by cooled casing
Internal and the cold wind of heating is re-fed into heat abstractor via the return air inlet of heat abstractor, via heat abstractor
Heat exchanger components cooling after, still sent by air outlet and cool down with the inside to electronics showcase or bulletin board casing,
And heat exchanger components is cooled down by the cold wind between heat abstractor air inlet and air outlet, it is ensured that by dissipating
The wind that thermal air outlet is sent is always cold wind, and then enters the inside of electronics showcase or bulletin board casing well
Row heat radiation.
