Heat accumulator

Abstract

Abstract PURPOSE:To prevent effective energy in a heat accumulator from deteriorating by separating thermally a part where a heat accumulating medium is molten from that where the heat accumulating medium is not molten, by dividing the inside of a heat accumulating container constituting a heat accumulator into a large number of divisions by heat insulating walls. CONSTITUTION:A large number of heat accumulating capsules 2 are incorporated into a heat accumulating container 3 at a certain interval with each other, the inside of the heat accumulating container 3 is separated into four divisions by three heat insulating partitions 10 and the heat accumulating capsules 2 are incorporated into each of division chambers 11-14. When a heat accumulating process is started, a thermal medium 4 of a high temperature is led through an inflow opening 9 of the upper part of a first division 11 to begin with, heat exchange is made with the heat accumulating capsules 2 in the division 11, whose temperature is decreased gradually while the heat exchange with the heat accumulating capsules in the second, third and fourth divisions 12-14 is being made in turn by passing through small holes 15-17 and streamed out from an outflow opening 18 of the bottom of the heat accumulating container 3. When a device is turned into a heat collecting process, the thermal medium of a low temperature to be heated is streamed in through the thermal medium outflow opening 18 of the bottom of the heat accumulating container, preheated by making heat exchange with the heat accumulating mediums in the divisions 14 and 13, heated up to a comparatively high temperature by making the heat exchange with heat accumulating mediums in the division 12 and 11 and streamed out from an upper inflow opening of the thermal medium.
