A heat absorber including a container providing an internal cavity, phase change material, such as microencapsulated phase change material, residing in the cavity, the container including at least one wall of thermally conductive material in thermal contact with the phase change material, such one wall provided with a plurality of spaced apart and inwardly extending members of thermally conductive material extending inwardly into the cavity and into and in thermal engagement with the phase change material, upon heat being transferred to the phase change material the phase change material changes phase and absorbs the heat. Such heat absorber in combination with electrical apparatus which produces heat when operating.
