Otsenka kharakteristik vakuumnykh tunnel'nykh diodov i vozmozhnosti ikh ispol'zovaniya v kholodil'noy tekhnike

Vacuum tunnel diodes (VTD) are a possible alternative to a vapor compression and thermoelectric mode to generate cold. The paper cites the VTD scheme and describes the basic of cold generation using the VTD. The overview of works on developing and calculating VDT is presented. The task to reduce work of electrons liberation from electrodes that is necessary for developing high effective cooling devices on the base of the VDT is considered. Theoretical estimations of the VDT performance with cold and hot metallic electrodes made of a ntype semiconductor are carried out. The results of calculations show that using VDT as basic elements in refrigeration systems is perspective. The calculated values of a specific refrigeration capacity and refrigeration coefficient of tunnel diodes exceed the corresponding values of thermoelectric energy converters several times. A maximal thermal gradient in the VDT may reach 210 K.
