Method of producing heat transfer plates, wherein the plates are shaped such that they comprise cavities for the passage of air. The plates are produced of heated synthetic material, in particular foils of synthetic materials, in a deep drawing method by using compressed air. The cavities of the plates form flow channels in which a lateral displacement exists at least in parts of their axial extension. When the plates are disposed on top of one another, said displacement abuts an edge of a flow channel of the plate arranged above or below.
