Apparatus (10) for cooling an object in contact therewith, comprises: a body (12) defining a sealed chamber (14) containing a refrigerant (16). The sealed chamber (14) has a first part (18) and a second part (20) spaced from the first part (18), with the second part (20) housing an adsorbent (22) configured to adsorb the refrigerant (16). The body (12) includes a valve arrangement (24) which is moveable from a closed configuration for isolating liquid refrigerant (16) in the first part (18) when not adsorbed in the adsorbent (22), to an open configuration for allowing refrigerant vapour to flow from the first (18) part to the second part (20). |
