Implementation method of plate-type evaporator

The invention relates to an implementation method of a plate-type evaporator. The evaporator comprises a series of heat exchange plates formed by stacking first heat exchange sheets and second heat exchange sheets at intervals, and the implementation method of stacking and combining the series of heat exchange plates comprises the following steps: respectively applying copper foils on the first surfaces of first heat exchange plates and second heat exchange plates, sequentially stacking the first heat exchange plates and the second heat exchange plates to which the copper foils are applied according to the number, heating the copper foil in a heating furnace to melt the copper foil, and enabling the first heat exchange plates and the second heat exchange plates to be combined at the mutual abutting position after solidification; subjecting the copper foil to punch forming and punching along with a substrate, and at least punching the copper foil at the position of a groove corresponding to the edge of a first
