Zusammenfassung:The invention provides an enhanced expansion type heat regenerator and a special Stirling cryocooler, and the enhanced expansion type heat regenerator comprises a heat regenerator shell as a shell of the enhanced expansion type heat regenerator; the multiple reinforced expansion type circulation channels are beneficial to circulation reinforcement of the compressed gas which is introduced into the reinforced expansion type circulation channels and oscillates alternately in the expansion direction, and the multiple reinforced expansion type circulation channels are tightly arranged in the heat regenerator shell side by side in an up-and-down penetrating mode; according to the reinforced expansion type heat regenerator, reciprocating oscillation compressed gas in the reinforced expansion type heat regenerator can move in the expansion direction more easily and is blocked when flowing in the opposite direction, so that the reciprocating oscillation gas participates in more expansion components, and the heat rege
