Cooling arrangement for use as switch cabinet-cooling device or as free cooler for cooling computer centers or office buildings, has heat exchanger that stays in heat conductive contact with phase change material held in heat accumulator

摘要

The cooling arrangement has a heat exchanger (20), to which a heat transport fluid is supplied, where the heat is extracted from and supplied to the heat transport fluid by the heat exchanger. The heat is partially introduced or removed from the heat exchanger. The heat exchanger stays in heat conductive contact with a phase change material held in a heat accumulator (21). The phase change material in the heat accumulator is paraffin or a material mixture containing paraffin or hydration water.
