Abstract:
1. Electronic circuitry comprising: a circuit board and at least one component mounted on the circuit board, the at least one component generating heat in use, the circuit board including at least one aperture aligned with the component or a respective one of the components, and the electronic circuitry being configured to provide, in use, a path for coolant fluid to flow through the at least one aperture and past the at least one component, the electronic circuitry being characterized in that it further comprises at least one opening providing a path to an ambient environment, wherein the at least one aperture and the at least one opening are arranged so that coolant fluid can flow in through the at least one aperture and out through the at least one opening thereby permitting the coolant to bleed into the ambient, and wherein a shutter is provided for the at least one aperture for varying a size of the at least one aperture.
