Description
Technical field
The utility model relates to a kind of controller switching equipment, specifically relates to the outdoor intelligent distribution box of a kind of automatic cooling.
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 casing of distribution box, have the purpose that louvre reaches cooling.It is low that these technology all exist radiating efficiency, and temperature is uneven in the casing, need leave ventilating opening simultaneously, causes dust to get into easily, reduces the particularly functional reliability of intelligent control device of box equipment; 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 the outdoor intelligent distribution box of a kind of automatic cooling; Adopt the combination of cooling technique of semiconductor and hot pipe technique; Through hot-side heat dissipation structure and the ingenious improvement of heat pipe layout, make that interior electric elements of outdoor machine distribution box and intelligent equipment can steady operations to semiconductor cooler.
The technical scheme of the utility model is achieved in that
The outdoor intelligent distribution box of a kind of automatic cooling comprises the interior automatic heat sink of installing of a plurality of intelligent control units, casing in casing, door, the casing; The sheet material of box bottom, 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; Above-mentioned a plurality of intelligent control units are layered in mutually in the casing, and cable terminal arranged space is all left in both sides; And the side of each intelligent control unit is glued with a block semiconductor refrigerating block; The hot junction of these conductor refrigeration pieces all has an independent heat pipe to connect, and heat pipe passes said cable terminal arranged space and is connected with radiator to the casing top, and the radiator limit at casing top is equipped with cooling fan; Described conductor refrigeration piece and power supply, temperature control circuit and cooling fan are formed automatic heat sink.
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 the most significant end of bin electric elements and intelligent equipment; The high temperature that its heating produces is directly passed to the conductor refrigeration piece through the apparatus casing side; The hot junction of conductor refrigeration piece is transmitted to the radiator at casing top again rapidly by heat pipe; The heat-exchange fin of radiator is by the air blast cooling of through-flow return fan, and the conductor refrigeration piece is controlled power supply by temperature control circuit, has realized automatic cooling.
The utility model is to rely on conductor refrigeration piece and heat pipe conduction cooling, no cross-ventilation in the cabinet, the cleaning of internal unit running environment at the closed case 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.
