PLATE FIN AND COMBUSTOR USING THE PLATE FIN

摘要

20This invention provides a plate fin which can attain low pollution combustionwithout the loss of pressure. The plate fin includes an internal wall panelwhich forms aninternal wall of a combustion chamber, an external wall panel facing theinternal wallpanel and forming a layer-form air flow passage between the internal wallpanel and theexternal wall panel, and a plurality of cooling fins disposed in the layer-form air flowpassage. The internal wall panel has a cooling air outlet, and the externalwall panel hasa plurality of cooling air inlets, both of which communicate with the layer-form air flowpassage. Each of the cooling fins has heat transfer plates which are disposedparallel tothe direction of cooling air flow through the layer-form air flow passage andconnectionplates which connect the heat transfer plates to each other.
