Fig. 2 is the structural representation for the charge power supply heat abstractor of variable propeller pitch control.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 2, for a charge power supply heat abstractor for variable propeller pitch control, comprise control cubicle 1, radiator 5, be horizontally installed on the dividing plate 2 in control cubicle 1 and be arranged in control cubicle 1 and be positioned at charge power supply 1 and the charge power supply 24 of dividing plate 2 one sides.The heating panel that radiator 5 is hollow, heating panel is along the Width horizontally set of control cubicle 1, and control cubicle 1 is stretched out at the two ends of heating panel, and one end of heating panel is air inlet, the other end of heating panel is installed by air exhauster 6 and as air outlet, air exhauster 6 adopts axial flow blower.Charge power supply 1 and charge power supply 24 symmetries are arranged on the both sides of heating panel, the interior uniform multiple heat radiation gear pieces 7 that arrange of heating panel, heat radiation gear piece 7 is along the length direction setting of heating panel, and the thickness of heat radiation gear piece 7 is 3.8～4.2mm, and the distance between adjacent two heat radiation gear pieces 7 is 3.8～4.2mm.Heating panel and heat radiation gear piece 7 are made by aluminium material, because heating panel is hollow structure, between heating panel inwall and heat radiation gear piece and adjacent two heat radiation gear pieces 7, form heat dissipation wind channel, heat dissipation wind channel and control cubicle 1 cabinet are isolated completely, have realized the hermetically sealed of control cubicle.Charge power supply 1 and charge power supply 24 symmetries are arranged on hollow heating panel, and the heat of its generation is directly passed to heating panel via contact-making surface, the long-pending high heat conductance that coordinates aluminium material of large contact surface, and heat can be covered with rapidly radiator.When temperature rise reaches after set point, air exhauster 6 is started working, and under air exhauster effect, cold wind enters radiator through air inlet, completes heat exchange, and discharge by air exhauster at internal heat dissipating gear piece, forms circulation.Because heat radiation gear piece air channel is unimpeded, the guide functions of air exhauster in addition, whole cyclic process is fast efficient.
