The cooling fluid is configured to be cooled upon contacting the cold source. A separation member is positioned between the first chamber and second chamber. The separation member separates the cooling fluid and the cold source. An activation device is connected to the separation member. The activation device is configured to cause the separation member to allow the cold source to contact the cooling fluid.
