Method for producing energy accumulators involves bags filled with accumulator fluid or fleece impregnated with accumulator fluid and inserted in housings for heat transmission

摘要

The method involves bags filled with accumulator fluid or fleece impregnated with accumulator fluid and inserted in housings for heat transmission. The housings are flowed through by a second heat transmission medium. The fluid is solidified by heat withdrawal and in solid form is filled into the bags before these are closed. The fleece (1) during heat withdrawal are formed into flat filling bodies (2), particularly or parallelepiped shape. The filling bodies on one side are provided with a narrowed formation (2a) as filling aid. Laterally, the filling bodies are inserted in a foil strip (4) which is endless and folded to U-shape and then provided in longitudinal and cross directions with welding seams..
