This paper proposes the small-size Stirling refrigerator with an active-type regenerator. When a n-type Stirling refrigerator with the regenerator in a displacer use light weight and flexible matrixes, those matrixes reciprocate in a regenerator housing. This phenomenon changes the flow loss and the residual gas volume in the regenerator matrixes. Moreover, the variation of the matrix volume influences the cooling capacity and COP. Then, we propose the active-type regenerator that actually transforms the matrix according to the reciprocation of the displacer. The active-type regenerator uses a urethane matrix that the swelling and compression are done by a matrix piston. The indicated cooling capacity of the Stirling refrigerator with the active-type regenerator is greater than the refrigerator with the conventional-type regenerator by about 1.3 times. Moreover, the indicated COP of the Stirling refrigerator with the active-type refrigerator is greater than the Stirling refrigerator with the conventional-type regenerator by about 1.5 times. The active-type regenerator has those advantage, we strongly recommend the small-size Stirling refrigerator with the active-type regenerator is put to practical applications.
