冰窖是用来长年储存冰的建筑物，在世界各地均有广泛使用，直到电冰箱发明后才被逐渐取代。冰窖常常是人工开掘的地下房间，建于淡水湖边等临近冬季自然冰的地方。

A cooler, portable ice chest, ice box, cool box, chilly bin (in New Zealand), or 'esky' (Australia) most commonly is an insulated box used to keep food or drink cool. Ice cubes are most commonly placed in it to help the things inside stay cool. Ice packs are sometimes used, as they either contain the melting water inside, or have a gel sealed inside that stays cold longer than plain ice (absorbing heat as it changes phase).
