Cooling arrangement implementing a photovoltaic device

A method for cooling an electronic device, the electronic device including a heat-generating component, the method comprising:

• inserting, at least in part, the electronic device in an immersion casing that contains a dielectric cooling liquid such that the dielectric cooling liquid collects, in use, at least a first portion of a thermal energy generated by the heat-generating component;
• and
• disposing a photovoltaic device proximate to the immersion casing and configured to convert at least in part a second portion of the thermal energy generated by the heat-generating component into electric energy, the second portion having radiated from the dielectric cooling liquid and through the immersion casing.

A cooling arrangement for cooling an electronic device, the electronic device including a heat-generating component, the cooling arrangement comprising:

• an immersion casing arranged to contain a dielectric cooling liquid, the electronic device being, at least in part, immersed in the dielectric cooling liquid, in use,
• a photovoltaic device positioned to convert thermal energy from the heat-generating component.
