The invention discloses a light and small electrocaloric refrigerating device, and belongs to the technical field of refrigerating equipment. The light and small electrocaloric refrigerating device comprises an electromagnetic driving part and a refrigerating core unit. A coil is connected into a direct-current power supply to generate a magnetic field, a magnetic loop is formed by the advantagesof high permeability, fast magnetization and fast demagnetization of soft magnetic ferrite, a stable magnetic field is generated below a soft magnetic ferrite plate, and a soft magnetic ferrite thin layer generates magnetic moment in the magnetic field and is tightly attached to the soft magnetic ferrite plate; and whether magnetic field torque exists or not can be controlled through an external power supply, and then reciprocating motion is achieved. The refrigerating core unit part is formed by adhering an electrocaloric material unit and a soft magnetic ferrite thin layer together through heat-conducting glue to form a whole with good heat conduction, and the electrocaloric material unit is of a completely packaged structure. According to the device, an electrocaloric material serves asa refrigeration core, cold and hot changes are achieved under an alternating electric field, reciprocating motion and heat conduction of the electrocaloric material unit can be achieved under drivingof electromagnetic force, and then the one-way rapid refrigeration function is achieved.
Description
technical field [0001] The invention belongs to the technical field of refrigerating equipment, in particular to a light and small electric card refrigerating device. Background technique [0002] With the development of the economy, refrigeration systems are increasingly used in various occasions to improve people's work and living comfort or provide a suitable working environment for some special equipment. [0003] With the development of refrigeration technology, refrigeration devices and equipment have gradually matured. However, in the current field of refrigeration, refrigerants with good thermodynamic properties such as freons are mainly used to realize refrigeration through a mechanical compression-evaporation cycle. This type of refrigeration technology has low efficiency, large equipment volume, and heavy weight, which cannot meet people's current needs for refrigeration, such as chip refrigeration, cooling of electronic products such as computers and mobile phon...
