Temperature regulation apparatus and method

A machine with a temperature regulation arrangement therein comprising:

• a closed area within the machine leading a temperature regulating chamber positioned adjacent a heat source,
• a liquid in the closed area,
• a head space within the closed area containing substantially only vapor of the liquid,
• a liquid collector within the head space configured to hold as a reservoir, wherein some of the liquid in the closed area is at an elevated height in the closed area,
• a first gooseneck conduit from said liquid collector to direct said liquid from within said liquid collector to a first lower level within the closed area,
• a feed take off from said first lower level,
• a second gooseneck conduit from said first lower level to a second lower level, wherein said second lower level is lower than said first lower level by which said liquid from within the first lower level is to be directed to said second lower level,
• a feed take off from said second lower level,
• wherein the shape of the second gooseneck conduit provides a height barrier to passage of said liquid there past, and
• wherein at least one of said first lower level and said second lower level comprises a reservoir.
