[0049] Below, refer to figure 1 and figure 2 A first embodiment of the heat exchange plate of the present invention will be described. figure 1 It is a schematic plan view of the heat exchange plate of this embodiment, figure 2 yes figure 1 partial sectional view. To simplify the drawings, in figure 1 The outline of the second groove 5 is omitted in .
[0050] like figure 1 As shown, the heat exchange plate (hereinafter referred to as the lining plate) of this embodiment has a main body 2 and a cover 3 .
[0051] The main body 2 is, for example, made of oxygen-free copper or a copper alloy containing less than 5% Zr or Cr, and is a rectangular plate-shaped member in plan view with a length of 2350 mm, a width of 2010 mm, and a thickness of about 15 mm. Moreover, on the upper surface (surface) 2a of the main body 2, there is provided a (first) groove 4 having a bottom surface 4a and a side surface 4b, for example, U-shaped in plan view and rectangular in cross-section,...

[0058] according to image 3 A second embodiment of the liner of the present invention will be described. image 3 is a partial cross-sectional view of the liner of this embodiment, and is the same as figure 2 same graph.
[0059] The liner of this embodiment differs from the above-mentioned first embodiment in that a main body 12 is provided instead of the main body 2 .
[0060] Components that are the same as those in the first embodiment described above are given the same reference numerals.
[0061] The main body 12 is, for example, made of oxygen-free copper or a copper alloy containing 5% or less of Zr or Cr, and is a rectangular planar member with a length of 2350 mm, a width of 2010 mm, and a thickness of about 15 mm. Further, on the upper surface (surface) 12a of the main body 12, there is provided a groove 14 having a bottom surface 14a and a side surface 14b, for example, U-shaped in plan view and rectangular in cross-section, or a corrugated groove in plan view...
no. 3 approach
[0070] according to Figure 4 A third embodiment of the liner of the present invention will be described. Figure 4 is a partial cross-sectional view of the liner of this embodiment, and is the same as figure 2 and image 3 same graph.
[0071] In the liner of the present embodiment, on each side face 6b of the protrusion 6 opposite to the side face 14b of the groove 14 when the protrusion 6 is inserted into the groove 14, a line (rib shape) is formed along each side face 6b of the protrusion 6. ) or a plurality of dot-like arrangements of minute notches (grooves) 20 recessed inwardly, which is different from the above-mentioned second embodiment in this point. The other components are the same as those of the above-mentioned second embodiment, and therefore descriptions of these components are omitted here.
[0072] The same reference numerals are assigned to the same components as in the second embodiment described above.
[0073] According to the liner of this embodim...
