Abstract

Изобретение относитс  к криогенной технике. Цель изобретени  - повшпение холодопроизводительности и ресурса работы. Рефрижератор содержит магнитокалорический элемент, теп- . лоотдатчик 2, теплоприемник 3 и кольцевой магнит 4 с полюсными наконечниками 5. Магнит 4 установлен с возможностью вращени  вокруг своей оси. Полюсные наконечники 5 снабжены зубчатыми выступами 6. Элемент выполнен в виде спирали и установлен неподвижно соосно кольцевому магниту 4 между выступами 6 полюсных наконечников 5, При вращении магнита 4 в рабочем теле возникает бегущее магнитное поле. Вследствие магнитокалорическо- го эффекта области в рабочем теле, наход щиес  в данный момент между выступами 6, намагничиваютс  и на- грепаютс , а остальна  часть рабочего тела размагничиваетс  и охлаждаетс . Так как нагретые и охлажденные области перемещаютс  вдоль рабочего тела, то возникает направленный тепловой поток от теплоотдатчика, который охлаждаетс , к теплоприемнику, который нагреваетс . 3 ил.This invention relates to a cryogenic technique. The purpose of the invention is to determine the cooling capacity and service life. The refrigerator contains a magnetocaloric element, tep-. the pilot unit 2, the heat receiver 3 and the ring magnet 4 with pole pieces 5. The magnet 4 is mounted for rotation around its axis. Pole tips 5 are equipped with toothed protrusions 6. The element is made in the form of a spiral and mounted stationary coaxially to the ring magnet 4 between the protrusions of 6 pole tips 5. When the magnet 4 rotates, a traveling magnetic field arises in the working body. Due to the magnetocaloric effect, the areas in the working body that are currently between the projections 6 are magnetized and strengthened, while the rest of the working body is demagnetized and cooled. As the heated and cooled areas move along the working fluid, a directed heat flow arises from the heat sink, which cools, to the heat sink, which heats up. 3 il.
