Heating device, in particular for the defrosting of freezer compartments

摘要

In a heating device, in particular for the defrosting of freezer compartments, pellicular resistive elements (16a,16b) are contained in close envelopes (14) made of electrically insulating material, each envelope (14) contains one or more pellicular resistive elements (16a,16b) electrically connected therebetween and the resistive elements (16) of each envelope (14) are electrically connected with resistive elements of at least one of the other envelopes so as to mantain the resistive elements (16) contained in said envelopes (14) electrically insulated. <IMAGE>
