A dehydrating device used in evaporator of a refrigeration (or an air conditioner) system, in which the evaporator includes a heat-exchanging assembly, and the dehydrating device includes an electrode member mounted under lower end of the heat-exchanging assembly at a suitable space, a positive voltage source, a negative voltage source, and two time controllers connected with the positive and negative voltage sources respectively; the two voltage sources are connected with the electrode member and the lower end of the heat-exchanging assembly respectively so as to form into an electric field therebetween; the two time controllers will provide a time difference so as to control the two voltage sources to furnish a power supply on a periodical switching basis; then, the condensed water under the heat-exchanging assembly will be pulled and removed from the surface of the heat-exchanging assembly by means of the periodical change of the electric field.
