Abstract
An apparatus for use in a wellbore comprises a heat insulating container having an inner space and having a structure defining a hollow containing a vacuum. The apparatus further comprises a reflective layer arranged on a surface of the heat insulating container to reflect heat for reducing radiated heat originated in the wellbore from reaching the inner space. Also, a signal-activated detonator is provided in the inner space of the heat insulating container.
