Gelpacks – icepacks as thermal energy generators or thermal accumulators
Ice packs and gel packs are cooling elements which are used to bring extra temperature preservation in passive cooling applications and packaging. Ice packs and gel packs can be produced as a single use or a multiple use cooling element depending on the logistic process of the customer. Ice packs and gel packs gain their energy by the pre-cooling or pre-heating of the elements in a freezer or heating device. Ones the energy has been stored the ice packs or gel packs are placed with the temperature sensitive goods within the passive cooling or packaging. The temperature preservation of the ice packs of gel packs is depending on a number of variables as the consistence of the ice pack or gel pack, the mass of the temperature sensitive products, the outer temperatures, the time of transport, the insulation quality of the passive cooling or packaging, etc.
