A PORTABLE TEMPERATURE CONTROLLED CONTAINER

摘要

This invention relates to a portable temperature controlled container [1] comprising a body [3] having a storage compartment [15], an opening to permit access to the storage compartment [15] and an insulated lid [5]. The container [1] comprises a fan [19], a heat sink [21] and a first thermoelectric device [23], as well as a first phase change material [31] and a second thermoelectric device [33] in thermal communication with both the first phase change material [31] and the storage compartment [15]. The second thermoelectric device [33] in thermal communication with both the first phase change material [31] and the storage compartment [15] is operable to transfer energy in the form of heat between the storage compartment [15] and the first phase change material [31]. The thermoelectric devices can be Peltier elements.
