Authors: Hramtsov M. V., Zabolotskiy A. M.

Annotation: It is known that the modern electronic component base (ECB), used in radio electronic equipment (REE) for various purposes, is operable only in a certain temperature range. At the same time, during the development of REE, the requirements are often made for guaranteed operation in more severe climatic conditions, including when exposed to negative temperatures. In this regard, it is necessary to ensure the given thermal regimes of REE. To do this, various heating devices are used, each of them makes it possible to ensure the operation of the electronic equipment under conditions of exposure to negative temperatures, by heating the ECB to the operating temperature. The paper provides a review, a comparative analysis, and gives recommendations on the use of modern ECB heating devices for REE under conditions of exposure to negative temperatures. This material can be used in the design of REE and help to ensure its thermal conditions.
