Abstract

The invention discloses a light and small electric card refrigeration device, which belongs to the technical field of refrigeration equipment and comprises two parts: an electromagnetic drive part and a refrigeration core unit. The coil is connected to a DC power supply to generate a magnetic field, relying on the advantages of high magnetic permeability of soft ferrite, fast magnetization and demagnetization to form a magnetic circuit, a stable magnetic field is generated under the soft ferrite plate, and the thin layer of soft ferrite is in the The magnetic moment is generated in the magnetic field, and it is closely attached to the soft ferrite plate; the presence or absence of the magnetic field moment can be realized through external power supply control, and then the reciprocating motion can be realized. The cooling core unit part is made of the electric card material unit and the soft ferrite thin layer glued together with heat-conducting adhesive to form a whole with good heat conduction. The electric card material unit is a packaged and complete structure. The device uses the electric card material as the cooling core, and realizes the change of cold and heat under the alternating electric field. Driven by the electromagnetic force, it can realize the reciprocating motion and heat conduction of the electric card material unit, and then realize the one-way rapid cooling function.

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...
