Description
Technical field
The utility model relates to a kind of power distribution cabinet, specifically relates to a kind of automatic cooling outdoor cabinet that when the power distribution cabinet temperature is too high, can lower the temperature automatically.
Background technology
Distribution box is that various electric elements are assembled in an electric equipment in the casing; Generally be installed in the open air; Owing to receive the influence of ambient temperature and self element heating, at summer high temperature season switch trip phenomenon in the distribution box can appear frequently, influenced power supply reliability; And the measure that we taked at present is: adopting mechanical small-sized fans aeration-cooling, is the purpose that reaches cooling through the heat radiation of fan forced ventilation.Perhaps on the cabinet of power distribution cabinet, have the purpose that louvre reaches cooling.It is low that these technology all exist radiating efficiency, and temperature is uneven in the cabinet, need leave ventilating opening simultaneously, causes dust to get into easily, reduces the functional reliability of equipment in the power distribution cabinet; In addition, the heat radiation of fan forced ventilation is because long-time running easy fault problem.Because so above-mentioned problem in use, is often just reported to the police to temperature is too high, the staff obtains overhauling after the alarm signal again, and efficient is not high.
On October 7th, 2009, Chinese utility model patent Granted publication CN 201323418Y discloses a kind of from lowering the temperature distribution box; Refrigeration and heat radiator is installed at top at distribution box, and this refrigeration and heat radiator comprises the installation from top to bottom successively of hot junction aerofoil fan, semiconductor refrigerating module and cold junction aerofoil fan, though this patent has proposed a kind of semiconductor refrigerating module cooling measure; But because the characteristic of semiconductor refrigerating module; The hot junction of semiconductor refrigerating module and the temperature difference of cold junction can not be excessive, and when the temperature difference surpassed 40 ℃, its Energy Efficiency Ratio will be less than 1; That is to say; When ambient temperature when higher, such as the summer of sweltering heat, this refrigeration and heat radiator but refrigerating capacity becomes worse and worse.Exactly during this time live load is maximum and be used to realize electric equipment, element in the distribution box body of utility model purpose; More need cooling; Therefore, this structure impacts the safe operation of power equipment easily, so be not suitable for extensive use in power equipment.
The utility model content
The purpose of the utility model provides a kind of automatic cooling outdoor cabinet; Adopt cooling technique of semiconductor; Through to the hot-side heat dissipation structure of semiconductor cooler and the ingenious improvement of rack inner air convection circulation environment, make that the interior electric elements of outdoor cabinet can steady operation.
The technical scheme of the utility model is achieved in that
A kind of automatic cooling outdoor cabinet comprises the electric elements mounting panel in cabinet, door, the cabinet, the semiconductor cooler that install at the cabinet top; The sheet material of cabinet base plate, side plate, backboard and door all is to adopt the two-layered steel plates assembly welding to form, and wherein, is filled with the insulation asbestos between sheet metal layer, and the specular aluminium rete is posted on the inner layer steel plate surface; The bending of above-mentioned electric elements mounting panel is L-shaped; Bottom surface and side have a plurality of return air holes; And bottom surface and side maintain spacing respectively and between the base plate of cabinet and backboard; This spacing forms an air duct naturally, and the air outlet of air duct is positioned at cabinet top, and a through-flow return fan is housed at the air outlet place; Above-mentioned semiconductor cooler mainly is made up of hot-side heat dissipation device, conductor refrigeration piece and the cold junction heat-exchange fin installed successively from top to bottom; The cold junction heat-exchange fin constitutes the inside ceiling panel of cabinet; The part that said hot-side heat dissipation device is close to the conductor refrigeration piece is a hollow heat-conducting block; The 4-8 root heat pipe under the inflection is tiltedly more vertically upward installed in the upper end of hollow heat-conducting block, and radiating fin is installed on the heat pipe; The two ends of every heat pipe connect the home loop that hollow heat-conducting block forms sealing, and can is used for the liquid of heat exchange in this home loop; The heat pipe of said hot-side heat dissipation device is positioned at the ridge shape protective cover of a coherent stream induced draft fan, and the heat loss through convection hole is opened in ridge shape protective cover side.
Compare with prior art, the utility model adopts technique scheme, gives the power supply of conductor refrigeration piece when power supply, and the conductor refrigeration piece is worked.Because the cold junction heat-exchange fin of conductor refrigeration piece is positioned at rack electric elements most significant end, the high-temperature hot air of electric elements heating generation rises naturally, runs into the cold junction heat-exchange fin part of lowering the temperature rapidly and descends again back from the surface cool electric elements; Another part force to be introduced air duct by the through-flow return fan, and the return air hole through electric elements mounting panel place directly blows to all electric elements of rack, realizes the electric elements steady operation.
The utility model hot-side heat dissipation device utilizes hollow heat-conducting block to collect heat from the conductor refrigeration piece; Making the liquid of can in the hollow heat-conducting block be evaporated to steam rapidly only rises to most significant end and/or inflection from the vertical component of heat pipe; Through-flow induced draft fan through radiating fin and ridge shape protective cover are installed on the heat pipe cools off the heat radiation of this steam; Because the bias part at inflection place heat pipe is longer than vertical component; The heat radiation condensation of steam occurs in bias part heat pipe easily relatively, therefore partly produces liquid return at bias.So move in circles, reach and utilize evaporation heat of liquids big, the characteristics that heat absorption is good are carried out the purpose of high efficiency and heat radiation.
The utility model is at the closed case environment temperature reduction, disobeys outer cross-ventilation, the cleaning of internal unit running environment.Can realize constant temperature and humidity, can guarantee that temperature humidity satisfies the requirement of electronic devices and components humiture, the damage of avoiding electronic devices and components to cause because of the humiture environment guarantees the normal operation of protection.The closed case of the utility model has been isolated the dust in the external environment, corrosive gas simultaneously, prolongs the useful life of electric component, has improved the reliability of machine greatly.This product is applicable to data processing, every field such as metallurgy, petrochemical industry, communication, building materials, Digit Control Machine Tool, electronics, tobacco, military project.
