The specific embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined purpose is taked, below in conjunction with drawings and Examples, to the described portable comprehensive test diagnosis equipment that the utility model proposes, describe in detail as after.
See also Fig. 1 and Fig. 2, portable comprehensive test diagnosis equipment described in the utility model mainly comprises casing 1, the embedded controller 2 of casing 1 inside and battery 3.For improving the heat-conducting effect of ABS plastic, portable comprehensive test diagnosis equipment described in the utility model has been fixed the heat-transfer metal plate 4 that adopts slim aluminium alloy to be processed into the drain pan shape on the housing of casing 1 inside, the heat energy that embedded controller 2 or other component distribute exports to outside the casing 1 fast by heat-transfer metal plate 4.
Further, on the described heat-transfer metal plate 4 plate radiating plate 5 and fan 6 are installed also.
The plate radiating plate of installing on the heat-transfer metal plate 45 is the tabular aluminium alloy structure, the one side of plate radiating plate 5 is pasted together by the back side of heat conductive silica gel and embedded controller 2, another side sticks on the heat-transfer metal plate 4 by heat conductive silica gel, and by screw flat fin 5 is fixed on the heat-transfer metal plate.Flat fin 5 utilizes the high thermoconductivity of heat-transfer metal plate 4 hot-air of casing 1 inside can be conducted to fan 6 exits.
Mounted fan adopts the fan 6 that can regulate rotating speed according to casing 1 internal temperature automatically on the heat-transfer metal plate 4, as shown in Figure 3, fan 6 is arranged in blower tray 12, fan 6 can be extracted the hot-air of casing 1 inside out by the air outlet that is provided with on the casing 1 among Fig. 4, make external environment condition and box house form draught head, accelerate cross-ventilation speed, thus control cabinet internal temperature rising speed.Raise as the cabinet inside temperature, the temperature control module that embedded controller 2 carries can send control signal to fan 6, improve the rotating speed of fan 6, accelerate convection velocity, reduce as the cabinet inside temperature, the temperature control module that embedded controller 2 carries can send control signal to fan 6, and the rotating speed that reduces fan 6 enters battery saving mode.
