Abstract: The application relates to a charging apparatus for inductively charging a separate, mobile apparatus. The charging apparatus includes a cooling system which is configured to enable additional phase change cooling of the mobile apparatus during inductive charging. The charging apparatus includes a flow path for providing a flow path for a phase-change cooling fluid to an interface with the mobile apparatus. The flow path enables cooling of, at least part of, the mobile apparatus when the mobile apparatus is being inductively charged by the charging apparatus. The flow path also includes wick structures that enable the phase-change fluid to be transported via capillary action.

Abstract: Examples of the disclosure relate to apparatus for cooling components such as electronic circuitry components and photonic components. A first component and a second component are provided on the same surface of a substrate. At least one temperature control means, such as a thermoelectric cooler. is configured to control the temperature of at least one of the components. The apparatus also comprises a plurality of heat transfer means that extend through the substrate from the first surface to the second surface. The plurality of heat transfer means enable heat to be transferred from the components to a heat pipe provided on the second surface of the substrate. This enables heat to be transferred through the substrate and away from the components and so can reduce the amount of heat that spreads laterally across the substrate. This allows for efficient removal of heat from the components and reduces heat transfer between the components.

Abstract: Examples of the disclosure relate to an oscillating heat pipe. The oscillating heat pipe includes a channel, a wick structure and a vent. The channel is configured to enable flow of working fluid between at least one condenser region and at least one evaporator region. The wick structure is in fluidic connection with the channel so as to enable working fluid to flow from the channel into the wick structure. The vent is configured to enable working fluid in an, at least partial, vapour phase to be returned from the wick structure to the channel.
