Abstract

The invention discloses a flexible electric card refrigeration device which comprises a flexible refractory paper substrate, a strontium nickelate bottom electrode layer, a barium strontium titanate electric card film layer and a platinum top electrode. The flexibility of the device is achieved by replacing a traditional rigid substrate with the novel flexible refractory paper substrate. The refractory paper can withstand high temperatures above 1000 DEG C, and can realize in-situ phase formation of the electrode and the electric card film. According to the invention, the preparation method issimple and low-costed, and the prepared device has the advantages of high refrigeration coefficient, noise prevention and small size, and can be widely used in the fields of submarine refrigeration components, robot heat dissipation, fire safety, medical treatment and health, wearable smart clothing, artificial intelligence and the like.

Description

technical field [0001] The invention belongs to the field of electric card refrigeration devices, in particular to a flexible electric card refrigeration device. Background technique [0002] Electric card refrigeration is different from traditional vapor compression refrigeration and is one of the new solid-state refrigeration technologies. The principle is based on the electric card effect. The electric card effect is the phenomenon that the electric dipole moment inside the electric card material is transformed into an ordered state or a disordered state through the application or removal of an external electric field, thereby causing the temperature change of the material. Electric card refrigeration is the best choice for future refrigeration technology due to its advantages of high refrigeration efficiency, no noise, low cost and short refrigeration cycle. [0003] At present, the society has a wide demand for refrigeration and heat dissipation. The development of big...
