Description of reference numerals: 1-shell, 2-condensation grid sheet, 3-semiconductor chilling plate, 4-heat radiation grid sheet, 5-radiator fan, 6-air inlet, 7-air outlet, 8-first sensor, 9-the second transducer, 10-water storage tank, 11-discharge outlet, 12-single-chip microcomputer, 13-heat shield.
Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, the utility model mainly comprises shell 1, is provided with condensation grid sheet 2 and heat radiation grid sheet 4 in shell 1.
Condensation grid sheet 2 rear ends are provided with semiconductor chilling plate 3, by 3 pairs of condensation grid sheets of semiconductor chilling plate 2, form refrigeration.Heat radiation grid sheet 4 rear ends are provided with radiator fan 5, by 5 pairs of heat radiation grid sheet 4 blowing heat radiations of radiator fan.
Further, between condensation grid sheet 2 and semiconductor chilling plate 3, be provided with heat shield 13, prevent from, between condensation grid sheet 2 and semiconductor chilling plate 3, exchange heat occurs, interact.
Described condensation grid sheet 2 is provided with the second transducer 9, shell 1 surface be provided with first sensor 8, the second transducers 9, first sensor 8, radiator fan 5 and semiconductor chilling plate 3 all be arranged on shell 1 in single-chip microcomputer 12 be electrically connected to.The second transducer 9 detects the temperature data on condensation grid sheet 2, first sensor 8 detects surrounding enviroment temperature data, then these temperature datas are sent to single-chip microcomputer, by single-chip microcomputer, according to default data judgement control radiator fan 5 and semiconductor chilling plate 3, whether are worked.
Under described condensation grid sheet 2, be provided with funnel shaped water storage tank 10, water storage tank 10 bottoms are provided with the discharge outlet 11 of leading to shell 1 outer end.The condensed water producing on condensation grid sheet 2 flows out by water storage tank 10 and discharge outlet 11.The condensed water that funnel shaped water storage tank 10 produces in can more efficient assembling supporting member also relies on condensed water deadweight to flow out.
