SHEET HEAT ACCUMULATING BODY OF FLOWING-DOWN TYPE HEAT ACCUMULATING DEVICE, LAMINATED SHEET HEAT ACCUMULATIVE BODY, DOUBLE LAMINATED SHEET HEAT ACCUMULATIVE BODY AND METHOD FOR PROCESSING SURFACE OF SHEET HEAT ACCUMULATIVE BODY

摘要

PURPOSE:To provide a sheet heat accumulative body for regulating a flowing-down direction of heat accumulative medium and collecting heat with a stable efficiency by a method wherein a surface of sheet material is formed with some fine linear corrugated patterns spaced apart along a flowing-down direction of heat accumulative medium and further flat and smooth surfaces are formed between the corrugated surfaces. CONSTITUTION:A surface of a sheet material is formed with some fine linear patterns 3 of corrugated surfaces spaced apart from each other. The fine corrugated surfaces are rich in wetting characteristics and form paths for regulating and guiding heat accumulative medium flowing down along the surface of the sheet material. The laminated heat accumulative body is constructed such that the heat accumulative medium flowing passages are formed between the fine corrugated surfaces of linear patterns 3 of the first contact sheet 1a and the contact surface of the second contact sheet 1b. Heat accumulative medium is present between a part 4 of the flat and smooth surface of the first contact sheet 1a and the contact surface of the second contact sheet 1b, and the two sheets are adhered to each other by the heat accumulative medium. With such an arrangement, a less-expensive heat accumulative body having some flow passages of wetting characteristics can be attained.
