Abstract: Embodiments included herein are directed towards an apparatus and method for manufacturing an electrical cooling apparatus. The method may include forming a first entirely solid metal plate to generate an enclosure. The method may also include affixing a bottom metal plate to the first entirely solid metal plate, the bottom metal plate may define a channel system. The bottom metal plate may include one or more inlet openings into the channel system, where the one or more inlet openings are configured to allow coolant to enter or exit the channel system.

Abstract: The invention relates to a safety system for a wind turbine, comprising a pitch system (23), which comprises a plurality of drive systems (15, 16, 17) and at least one safety switching device (24), by means of which each of the drive systems (15, 16, 17) can be controlled to carry out a travel to a safe position in accordance with at least one control signal, a safety circuit, which is provided in a machine part adjacent to the pitch system (23) and which comprises a transmission device (32) and a controller (29), by means of which the at least one control signal can be generated, which can be transmitted from the controller (29) to the safety switching device (24) by means of the transmission device (32), wherein the control signal can be generated and/or output by the controller (29) in the form of at least two control signals (EFC 1, EFC 2), the control signals (EFC 1, EFC 2) can be transmitted from the controller (29) to the safety switching device (24) by means of the transmission device (32), a safety-r
