The invention discloses a phase change cold storage device based on a shape memory alloy and a cold storage method. The cold storage device comprises the shape memory alloy used for storing energy and providing cold energy, a connecting rod compression structure used for applying loads and a self-locking structure used for keeping the stress loading state. The connecting rod compression structure comprises a machine shell, the upper surface of the machine shell is hinged to one end of a connecting rod, the other end of the connecting rod is hinged to one end of a sleeve, the other end of the sleeve is hinged to the upper end of a pressing rod, a handle is inserted into the sleeve, the lower end of the pressing rod is connected with a pressing disc, and the pressing disc and shape memory alloy are arranged in the machine shell. The lower surface of the pressing disc is in close contact with the shape memory alloy, external acting force is applied to the pressing disc through the pressing rod, and the pressing rod moves downwards to drive the pressing disc to compress the shape memory alloy downwards; and the self-locking structure enables the external acting force to be withdrawn through a locking pressing rod, and then the loading state is still kept. Efficient cooling capacity storage is achieved, and meanwhile quick release and transfer of the cooling capacity are achieved by means of the energy release process characteristics of the shape memory alloy.
Description
technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to a phase-change cold storage device and a cold storage method based on a shape memory alloy. Background technique [0002] The development of society is accompanied by the continuous increase of human demand and the shortage of non-renewable energy. As a measure to effectively realize the "peak shifting and filling valley" of electric energy, energy storage technology has become a hot spot in the world's energy utilization and materials research. Among them, cold storage technology, as a branch of energy storage technology, its main methods include: sensible heat cold storage, ice cold storage, inorganic compound or organic compound cold storage and phase change cold storage. Although there are various ways of cold storage technology, there are still many problems in its application. The traditional water cold storage has poor thermal insulation effect and huge ...
