Abstract:
A casing for containing apparatus which in use generates heat, the casing including a heat exchanger arranged to act as a removable wall (preferably a lid) of the casing, and fluid directing means arranged to be on the exterior of the said removable wall for directing a heat transfer fluid in thermal contact with the said wall in use, such that heat generated in the interior of the casing is transferred to the heat transfer fluid by conduction through the material of the said wall.
Abstract:
Articles and methods are provided for enclosing an elongate substrate. A container is provided which is configured to receive the elongate substrate. A first polymeric sealing material having a first softening point and a first melt viscosity is positioned in the container. A second polymeric sealing material is positioned in the container between the first sealing material and an end of the container. The second sealing material has a second softening point lower than the first softening point and a second melt viscosity lower at a defined temperature than the fist melt viscosity.
