In the case of a rail-fixing system according to the invention, the individual elements are arranged on the flat surface (2) of the firm underlying surface (1) available in each case. In this case, the positional fixing of an angular guide plate (11, 12) does not take place via projections or depressions formed on the underlying surface (1) but rather via a separate angle bracket (18, 19). During the installation of the fixing system according to the invention, this angle bracket (18, 19) can easily be positioned in each case in such a manner that optimum support of the angular guide plate (11, 12) is ensured irrespective of its particular orientation on the particular underlying surface. The fixing system according to the invention can thereby build on a known system from which it takes most of the components, such as the elastic intermediate layer (4), pressure-distributing plate (8), spring element (26, 27) and clamping element (28, 29).

A power conversion apparatus is provided, which comprises a housing, a mother board, an electromagnetic filter board, a signal board, and a heat-dissipation module. The housing includes a first heat-dissipation wall and a coolant passage. The mother board is disposed upon the housing, and comprises a first surface facing the housing and a first power device. The heat-dissipation module includes a first insulated heat-conducting sheet adhered to the corresponding first heat-dissipation wall and a first elastic clamp. When the first surface of the mother board approaches the housing to clamp the first power device within the accommodating space, the first power device is pressed against by the first elastic clamp and thus adhered to the first insulated heat-conducting sheet, so that the first power device is thermally coupled to the first heat-dissipation wall and the coolant passage via the first insulated heat-conducting sheet.
