The present invention provides a foldably packed temperature adjustment fan, which comprises a water tank assembly, having a water storage cavity; and a shell assembly, mounted on a top of the water tank assembly, wherein the shell assembly comprises a plurality of side plate assemblies for surrounding and forming an airflow cavity and a top plate assembly, at least a part of the side plate assemblies are respectively utilized as a whole body and are detachably mounted on an edge of the top of the water tank assembly, and at least a part of the side plate assemblies can be completely accommodated in the water storage cavity after being detached. The present invention further provides a folding method of the foldably packed temperature adjustment fan. When the temperature adjustment fan of the present invention is used, its appearance is the same as that of a normal unit; during packing, a rear plate assembly, a left side plate assembly and a right side plate assembly can be completely accommodated in the water tank assembly, a front panel assembly does not need to be detached, and as long as the front panel assembly is turned over, fast folding is completed; and the package size is small, associated components are less, and logistics transportation is convenient.

A laser machine for machining workpieces has a workpiece support that forms a support main plane and is permeable to air perpendicularly to the support main plane. Supply air is directed to an upper side of the workpiece support. Air that is contaminated due to machining is discharged as exhaust air from the upper side of the workpiece support through the workpiece support to the bottom side of the workpiece support. In order to generate a laminar supply air flow which is perpendicular to the upper side of the workpiece support, the flow cross section of the supply air channel is divided into partial cross sections by partial cross sectional walls.
