Abstract
The invention relates to a liquid cooling element for cooling heat generating elements of frequency converters, in particular, and an arrangement for connecting the liquid cooling element. The liquid cooling elementis provided with two channel systems: horizontal channelsand transverse channelsconnecting said horizontal channels. The liquid cooling elementis characterized by consisting of one integral piece, the transverse channelsbeing arranged eccentrically to the horizontal channelssuch that the longitudinal axis of the transverse channelis closer to the lateral face of the cooling element than the longitudinal axis of the horizontal channeland the outer edge of the transverse channelextends closer to the lateral face of the cooling element than the outer edge of the horizontal channel. The liquid cooling element is connected to protect the liquid cooling against leakage such that around the pipes supplying cooling liquid into the horizontal channels there is arranged a second pipehaving a larger diameter.
