A cooling device configured to be mounted in close proximity to an electronic component that is to be cooled is provided. In one aspect, the device includes impingement channels and return channels for guiding a flow of cooling fluid towards and away from a cooled surface of the electronic component. The device also includes a heat exchanger and a pump, so that the flow cycle of a cooling fluid is fully confined within the device itself. The impingement channels, the return channels, and the heat exchanger are integrated in a common housing, which includes an inlet opening and an outlet opening for coupling the device to a refrigerant loop. The pump may be a micropump mounted directly on the housing and coupled to the inlet and outlet openings in the housing. A cooling system including the device and the refrigerant loop is also provided.

Device and system for cooling an electronic component

An assembly including a carrier substrate and at least one group of interconnected integrated circuit modules mounted thereon is disclosed. The modules are provided with a connection for transmitting a clock signal through the group of interconnected modules. The modules are also provided with digital input ports and output ports and a logic circuit configured for identifying the position of the modules in the group on the basis of a count of the clock pulses, and on the basis of the logic state of the input and output ports. In one aspect, a method involves the transfer of a token in the form of one or more logic states, through the group of modules, from a first module to a last module, resulting in the identification of all modules in a progressive manner.

Assembly of integrated circuit modules and method for identifying the modules

A liquid cooling system for cooling an electronic device comprising a chip or a chip package comprising a chip is described. The liquid cooling system comprises an inlet plenum comprising a coolant feeding channel oriented substantially parallel with the plane of a main surface to be cooled of the chip and a plurality of inlet cooling channels fluidically connected to the coolant feeding channel and arranged vertically for impinging a liquid coolant directly on said main surface of the chip. The vertically oriented inlet cooling channels are substantially parallel to vertically oriented outlet cooling channels and are separated by a thermally isolating material. The liquid cooling system further comprises at least one cavity wherein a plurality of inlet and outlet cooling channels end. The cavity is arranged for allowing interaction between the liquid coolant and the main surface of the chip and thus comprises a heat transfer region.
