海綿状物質に含浸される。The other storage section (the front side that comes into contact with the head, etc.) stores an antifreeze material and a water-absorbing spongy material. The antifreeze material is impregnated with a water-absorbing spongy material.
不凍性物質は、モノ−、ジー、エチレングリコール等を
通常３０％以上の水溶液として用いる。As the antifreeze substance, mono-, di-, ethylene glycol, etc. are usually used as an aqueous solution of 30% or more.
吸水性海綿状物質は、ウレタンマット、天然海綿等、柔
らかくて、不凍性物質を含浸することかできるものであ
る。The water-absorbing spongy material is soft and can be impregnated with an antifreeze material, such as a urethane mat or natural sponge.
また、これらの成分以外に、ゲル状蓄冷剤やほう砂等を
使用こともてきる。Moreover, in addition to these components, gel-like cold storage agents, borax, etc. can also be used.
