Embodiment
Below pass through embodiment, and combine accompanying drawing that the utility model is described further.
Extremely shown in Figure 6 like Fig. 4; The automatically controlled box of a kind of idle call of the utility model comprises main body box 1, lid 2 and automatically controlled pcb board 3, and automatically controlled pcb board 3 is fixed in the main body box 1; Main body box 1, lid 2 are made of plastics; Automatically controlled pcb board 3 is an overall structure, and main body box 1 bottom is provided with some reference columns 11, and automatically controlled pcb board 3 is fixed between first baffle plate 12 and second baffle 13 of main body box 1; Spacing buckle 121 is arranged on first baffle plate, 12 inboards of main body box 1, and positive stop lug boss 131 is arranged on second baffle 13 inboards of main body box 1; Spacing buckle 121, positive stop lug boss 131 cooperate with reference column 11 automatically controlled pcb board 3 are fixed in the main body box 1.Automatically controlled pcb board 3 is an overall structure; Well integrate original irony electric-controlled box 1 ' automatically controlled three-lane road; Be module board 11 ', PFC (power factor correction) plate 12 ' with power panel 13 ' repertoire, this kind structure makes automatically controlled pcb board 3 convenient disassemblies, saves a lot of patchs trouble; Increase work efficiency, priorly be convenient to judge fast fault and maintenance.The plastics electric-controlled box is because of itself light weight, and automatically controlled pcb board 3 is integrated into a plate, shortens its space mounting length undoubtedly, in the time of can avoiding being installed in off-premises station and the off-premises station internal part bump and not first-class interference risk be installed.
Second side plate, 15 outsides of main body box 1 also are provided with threading opening 152, and threading opening 152 is made up of two or above U type groove; The height ecto-entad of U type groove increases progressively gradually, even and then avoid power line to have the part globule can not flowing to electric-controlled box inside along wire harness, combine the Seal Design of lid 2 can effectively stop again and get rid of that to get into electric-controlled box into the globule inner because of fan blade rotates.
As shown in Figure 6: main body box 1 bottom is provided with a window 17, and three spacing lugs 18 of window 17 1 sides will be fixed on window 17 downsides by the heat sink 4 that many fin are formed with the screw in the two-screw hole that is installed in window 17 opposite sides 19.The card module of automatically controlled pcb board 3, IGBT, fast recovery diode can be fastened on the heat sink 4; Because the cause that insulate of plastics electric-controlled box itself; Just saved former irony electric-controlled box 1 ' middle plastic barrier frame 16 ' with screw cover 15 ' and parts such as empire cloth; Effectively reduce manual work and material cost, but also fundamentally effectively stop electrical safety hidden danger.
In conjunction with shown in Figure 7, air-conditioner outdoor unit comprises casing 5, condenser 6, and by the fan blade 7 of driven by motor, on median septum 8, the other end passes through screw on right plate 9 through screw for median septum 8, right plate 9 and baffle liner 10, automatically controlled box one end of idle call.Median septum 8 effect is a side of fully fixedly electric-controlled box and this body weight of electric-controlled box is played supporting role effectively, the installation site of inductor 31 is provided simultaneously.Main body box 1 heat radiation air outlet 141 and the bottom of first side plate 14 air vent hole that is provided with several different sizes used heat that compressor run well produce also can volatilize and rise to the electric-controlled box inner space; Superpose automatically controlled pcb board 3 self used heat savings in airtight electric-controlled box inner space; According to aerodynamic principle; In case the fan blade 7 by driven by motor runs up and outwards air draft; Air just forms along electrical axis direction (being the round center of fan blade 7) under the ordering about of the fan blade 7 of high speed rotating, forms a local depression vortex that air pressure is low relatively; The pressure of electric-controlled box device this moment inner (being automatically controlled pcb board 3 superjacent air spaces) equates with off-premises station outside pressure, promptly all is a standard atmospheric pressure.The internal heat air of electric-controlled box is pressed into the low pressure vortex through heat radiation air outlet 141 like this, discharges off-premises station through the baffle liner 10 of off-premises station front panel again.In like manner can know, the cooling air in the off-premises station outside can be endlessly air inlet passage through right plate 9 be pressed into electric-controlled box.In brief; The inner cooling air wind direction of electric-controlled box flow direction is: it is inner to get into electric-controlled box from the off-premises station outside through the air inlet of off-premises station right plate 9; Get into by 7 runnings of driven by motor axial-flow leaf from electric-controlled box heat radiation air outlet 141 again and form the low pressure vortex; Flow into baffle liner 10 then and flow out the off-premises station outside again, thereby form a complete and effective heat radiation wind direction flow circuits, carry out cycle heat radiation for electric-controlled box inside.
Be in the fin 4 in the low pressure whirlpool district equally; Its cooling air is pressed into the low pressure vortex from condenser 6 outsides exactly; Carry out exchange heat with fin 4 in parallel; Run up by the fan blade 7 of driven by motor by off-premises station afterwards and discharge, thus the purpose of handling for its wind cooling temperature lowering, and its cooling air direction that flows is: get into condenser 6 from the off-premises station outside; Form the low pressure vortex through the back inflow of fin 4 surface by 7 runnings of driven by motor fan blade, get into baffle liner 10 backs again and flow out the off-premises station outside.Thereby form another complete and effective heat radiation wind direction flow circuits, carry out cycle heat radiation for fin 4; Simultaneously this structure effectively solves Chinese utility model patent ZL200420065346.1 electric-controlled box inside and does not contain heat dissipation wind channel, and confined space inner compressor used heat can't be discharged, and also need carry all drawbacks that the fan blade 7 of forced convertion dispels the heat.
