Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings.
nullA kind of protective housing in embodiment as shown in Figure 1 to Figure 3，Including main casing 1，Described main casing is provided with horizontally disposed main air inlet pipe 2、An air inlet pipe 3 of some vertical layouts，Main air inlet pipe is fixed on main casing inner top，Main air inlet pipe one end open、One end is closed，Main air inlet pipe opening and atmosphere，It is provided with air intake blower fan 21 in main air inlet pipe opening，Prop up air inlet pipe to be in main casing，Prop up air inlet pipe upper end to connect with main air inlet pipe，Prop up air inlet pipe lower end closed，Prop up air inlet pipe and be provided with the horizontal venthole 31 that a row is vertically distributed，Main casing sidewall is provided with some housing steam vents 11，In the horizontal venthole of any two in one air inlet pipe: horizontal venthole aperture up, place is less than horizontal venthole aperture at the bottom,Main casing inner bottom part is provided with heat-conducting padding plate 5，Heat-conducting padding plate is provided with some perpendicular fin 51，Perpendicular fin upper end passes bottom main casing and connects heat-conducting padding plate bottom surface，Perpendicular fin lower end is outside main casing,Prop up and threaded between air inlet pipe upper end with main air inlet pipe.Air intake blower fan is for sucking in main casing by extraneous air, air advanced person becomes owner of in air inlet pipe, is then dispersed into each air inlet pipe, and air-flow flows in bronchus from top to bottom, and discharge through each horizontal venthole, thus it is internally formed scattered multiple tracks radiating airflow at main casing.In prior art, it is common that " extensive " air inlet and aerofluxus, so when circuit electrical element or other structure are after local hinders air flowing, and air-flow will walk around these parts, is expelled directly out, and easily causes local heat radiation smooth (accumulated heat).Owing to having multiple tracks air-flow, broad covered area, and each air-flow has certain independence, can effectively dispel the heat for each position, and overall flow direction of air-flow is by main air inlet pipe opening to housing steam vent, thus radiating airflow can effectively be taken into account everywhere, it is to avoid in prior art, air flow direction is single, when circuit electrical element or other structure are after local hinders air flowing, the problem that the local heat radiation that caused is the most smooth.Heat-conducting padding plate (can be various metallic plate; such as copper coin) can quickly absorb the heat that main casing internal (circuit electrical element etc.) produces; and pass and be delivered to the external world by each perpendicular fin, and perpendicular fin is all disposed within main casing bottom position, can obtain the protection of main casing.In addition, each air inlet pipe slightly turn (threadeding between its upper end with main air inlet pipe) can regulate the air-out direction of horizontal venthole, cooling air-flow is allowed directly to blow to the position with greater need for heat radiation, such that it is able to better adapt to the heat radiation of the circuit electrical element etc. of different structure targetedly.
nullDescribed main air inlet pipe opening passes through preposition cleaner and atmosphere，Preposition cleaner includes whirlwind cone cylinder 41、Inner filter net cylinder 42、Tangential admission pipe 43、Interior trachea 44、Circle shrouding 45，Vertical clapboard 12 it is provided with in main casing，Vertical clapboard will be separated into electric chamber 13 inside main casing、Filtering chamber 14，Whirlwind cone cylinder is in filtering intracavity，In whirlwind cone cylinder、The equal opening in lower end and upper end open are more than lower ending opening，On Inner filter net cylinder、The equal opening in lower end，Inner filter net cylinder lower ending opening is sealed by a sealed piece，Inner filter net cylinder is in whirlwind cone cylinder and Inner filter net cylinder is provided with multiple filtering holes，Whirlwind cone cylinder upper end open and Inner filter net cylinder upper end open are all sealed by circle shrouding，Circle shrouding is provided with the plate hole that connect internal with Inner filter net cylinder，Tangential admission pipe one end connection whirlwind cone cylinder，The tangential admission pipe other end is opened on main casing sidewall and and atmosphere，Interior trachea one end through vertical clapboard and connects with main air inlet pipe opening，The interior trachea other end connects with plate hole，Interior trachea is provided with filter mesh layer.Electrically chamber is used for installing and accommodate circuit electrical element etc., outside air has dust impurity, under the effect of air intake blower fan, extraneous air enters tangential admission pipe, and by tangential or approximate tangential in the way of enter in whirlwind cone cylinder, and in whirlwind cone cylinder, form eddy flow, the dust impurity of relatively heavy (bigger) is adherent, gradually falls due to gravity subsequently, and air draught then enters Inner filter net cylinder by each filtering holes, and reach up to plate hole, with after reach main air inlet pipe through interior trachea.Filter mesh layer internally can carry out fine straining by the gas in trachea again, dust impurity under Lv drops down onto (falling into) sealed piece, thus, the radiating airflow provided by main air inlet pipe, through filtering, can greatly reduce the dust stratification of circuit electrical element, the problem that can avoid the heat-sinking capability difference caused because dust stratification is too much.
Described sealed piece is the interior ash cylinder 421 of a upper end open, and threadeding with Inner filter net cylinder lower end in interior ash cylinder upper end, is provided with shutter door 15 bottom main casing, and shutter door is in below interior ash cylinder, and shutter door seals whirlwind cone cylinder lower ending opening.Described main casing includes roof lid 1a, body 1b, is connected fixing between roof lid and body by some screws.When needs deashing, can open shutter door (shutter door at ordinary times can with clamping bottom main casing, threaded, as long as open and close function can be realized), make dust impurity fall, interior ash cylinder can be screwed off subsequently, internally " fine ash " in ash cylinder topples over.Main casing dismounting is convenient, is beneficial to safeguard and cleaning.
