The two-phaseflow refrigerating device based on the electric heating effect has the advantages of scientific design, simple structure, continuous heat transfer and improvement of the heat dissipating power and thetemperature span.

Description

technical field [0001] The invention relates to the field of solid refrigeration, in particular to a two-phase flow refrigeration device based on electrothermal effect. Background technique [0002] At present, domestic and foreign research on the use of electrothermal effect for refrigeration mainly focuses on the development of materials with high electrothermal effect, such as PbZrTiO3 thin film and BaTiO3, as well as other thin film ceramics and polymers. With the development of the economy, devices are developing toward miniaturization, especially the refrigeration technology in electronic equipment is particularly important. Electronic chips will generate a lot of heat during the working process, and the accumulation of heat will cause chip failure and damage. According to investigations and research, more than half of the current electronic device damage is caused by thermal failure. Therefore, timely heat dissipation of electronic devices is the key Necessary safegu...

Problems solved by technology

At present, the main problem of electrocaloric effect refrigeration based on materials with electrocaloric effect is that the existing electrothermal effect refrigeration devices cannot achieve continuous heat transfer due to the limitation of the application and removal time of the electric field, so the heat dissipation power and temperature span are low, which cannot meet the requirements.
