Abstract
The present invention relates to a stack of substantially flat plates stacked one on top of the other along a stacking direction. The substantially flat plates define at least a first plate interspace between a first plate and an opposing second plate of the stack. One of the plates in the first plate interspace defining a first ridge protruding a first distance in the first plate interspace. The first distance is less than the thickness of the plates in the first plate interspace. The plates in the first plate interspace being permanently joined at the first ridge.

A stack of substantially flat plates stacked one on top of the other along a stacking direction, the substantially flat plates defining at least a first plate interspace between a first plate and an opposing second plate of the stack, one of the plates in the first plate interspace defining a first ridge protruding a first distance in the first plate interspace, the first distance being less than the thickness of the plates in the first plate interspace, the plates in the first plate interspace being permanently joined at the first ridge.
A method of manufacturing a stack of substantially flat plates comprising the steps of:
- stacking the substantially flat plates one on top of the other along a stacking direction, the substantially flat plates defining at least a first plate interspace between a first plate and an opposing second plate of the stack, one of the plates in the first plate interspace defining a first ridge protruding a first distance in the first plate interspace, the first distance being less than the thickness of the plates in the first plate interspace, and
- permanently joining the plates in the first plate interspace at the first ridge.
