    摘要: The invention relates to a heat exchanger comprising a base plate for receiving a heat load from one or more electric components, an evaporator being in thermal contact with a surface of the base plate for transferring said heat load into a first fluid in the evaporator channels, and a condenser dissipating heat from the first fluid. In order to provide an efficient heat exchanger the heat exchanger comprises a collector space receiving first fluid from the condenser, and the collector space which is located higher than the lower ends of the evaporator channels is in fluid communication with lower ends of the evaporator channels for passing first fluid received from the condenser to the lower ends of the evaporator channels.

    摘要: A heat exchanger assembly (1) is disclosed. The heat exchanger assembly comprises at least one passive cooling circuit (100), the passive cooling circuit comprising an evaporator (110) connectable to a device (50) to be cooled for conducting heat from the device (50) to be cooled to the cooling fluid within the evaporator (110), thereby evaporating the cooling fluid, and a condenser (120) interconnected with the evaporator (110) for receiving the evaporated cooling fluid from the evaporator (110), releasing heat from the cooling fluid to an environment of the condenser (120), thereby condensing the cooling fluid, and for returning the condensed cooling fluid to the evaporator; and an active partial circuit (200) comprising a compressor (250) and an auxiliary condenser (220), the active partial circuit (200) being activatable and deactivatable and being connected to the passive cooling circuit for receiving, in an activated state of the active partial circuit (200), the cooling fluid from the evaporator (110), for compressing the received cooling fluid by the compressor (250), for releasing heat, by the auxiliary condenser (220), from the compressed cooling fluid to an environment of the auxiliary condenser (220), and for returning the condensed cooling fluid to the evaporator (110). Furthermore, the passive cooling circuit (100) is a base-to-air type thermosiphon or an air-to-air type thermosiphon.

    摘要: A surge arrester system includes a surge arrester, and an active cooling system having a cooling interface in contact with the surge arrester and operative to transfer heat from the surge arrester. The active cooling system includes a forced convection apparatus operative to provide forced convection cooling. A circuit breaker system includes a power semiconductor switch and an active cooling system constructed to cool the power semiconductor switch. The active cooling system includes a forced convection apparatus configured to provide forced convection cooling. The power semiconductor switch is in contact with the active cooling system. A surge arrester is disposed adjacent to and in contact with the active cooling system. The active cooling system includes a cooling interface constructed for contact with the surge arrester and operative to provide cooling to the surge arrester. The power semiconductor switch and the surge arrester dissipate power alternatively.
