A concave-convex metal plate of a floor heating system according to the present disclosure includes repeatedly bent concave and convex portions to transmit a load from an upper portion of a finishing material to a floor slab. Because the concave-convex metal plate includes the repeatedly bent concave and convex portions, resistance to the load from the upper portion is significantly improved, thus functioning as a floor structural material that may sufficiently withstand the load, while transferring the load from the upper portion of the finishing material to the floor slab.

Provided are an asynchronous heating and calendering device, a large wide ultra-thin lithium metal foil, and preparation method and use thereof, wherein the asynchronous heating and calendering device comprises: a pulling-substrate unwinding unit (E) for unwinding a pulling-substrate (P); a lithium strip unwinding unit (D) for unwinding a lithium strip (S); an asynchronous heating and calendering unit (H) which comprises: a first calendering roller (B), a second calendering roller (A) and a heating box (C), wherein the heating box (C) is used to heat the first calendering roller (B), the first calendering roller (B) heats the pulling-substrate (P), and the first calendering roller (B) and the second calendering roller (A) have parallel axes and are arranged opposite to each other, so that the pulling-substrate (P) and the lithium strip (S) are combined into a composite strip (Z); and a winding unit (G) for winding the composite strip (Z). A large wide ultra-thin lithium metal foil with a uniform thickness may be prepared by providing a heating box (C) and asynchronous first calendering roller (B) and second calendering roller (A) in said device, and the application of this lithium foil in batteries has a relatively high initial efficiency. The width of the lithium foil is 1-600 mm; the thickness of the lithium foil is 1-20 μm; and the initial efficiency of the battery reaches 98%.

A heat exchanger includes a plurality of flat heat transfer tubes each having a flat cross-sectional shape, a flat outer side surface, and an interior defining a passage through which a fluid flows, the plurality of flat heat transfer tubes being arranged with the flat outer side surfaces facing each other, and a plurality of corrugated fins each having a wavy shape, each of the plurality of corrugated fins being disposed between and joined to flat heat transfer tubes of the plurality of flat heat transfer tubes that are adjacent to each other. Each of the plurality of corrugated fins has portions that correspond to peaks of the wavy shape and have lower flexural rigidity than other portions of the corrugated fin.

The present invention relates to a cladding or covering sheet for roofs or walls including a plurality of first fold lines or ribs spaced apart from each other and a plurality of second fold lines or ribs spaced apart.

A tool for manufacturing blanks and a process for stacking and destacking the blanks in a production line are provided. The tool is incorporated into a blanking die used to trim a metal sheet and form the blanks. When the blanks are stacked, the destacking formations provide gaps between the adjacent blanks. The gaps provide an entry to blast air and thus reliably separate the blanks for pick up, so that only one blank is picked up at a time. The tool includes a deforming unit that has an engagement element for pressing deformations into the metal sheet. The deformations are pressed adjacent to at least one edge of the metal sheet so that when the metal sheet is trimmed, and the blanks are stacked, they are spaced by the deformations by adjacently stacked blanks.

The present invention relates to a method and a device for manufacturing plate part blanks for a heat exchanger. A sheet material (2) in the form of continuous sheeting is worked between two rolls (5, 6) with opposite surface patterns (7, 7′, 8) to form profiled plate part blanks (3, 3′,3″) into the sheet material (2) so that the rolls (5, 6) are synchronized to rotate at substantially same rate by controlling the rotation of them in relation to each other with common synchronization gear (9), which gear is coupled to the rolls (5, 6) by means of shafts (10, 11) with disk pack or gear couplings.
