    摘要: A plate heat exchanger includes a heat exchanger block having a plurality of heat exchange passages. On the heat exchanger block, a header is mounted that extends over at least one part of one side of the heat exchanger block and establishes a flow connection between the heat exchange passages. The plate heat exchanger is provided with a fluid connection, which is formed by the header-side end of a pipeline. The fluid connection is essentially perpendicular to the side of the heat exchanger block over which the header extends. Within the pipeline directly in front of the header, there is a flow guide.

    摘要: The present invention relates to a method to supply power to an LED array, comprising at least two LED branches connected in parallel, in each of which at least one LED is arranged. The LED array is supplied with predetermined power from a current source connected in series, wherein currents are measured in the LED branches, wherein the measured currents are compared in control electronics, and wherein the currents are controlled in a part of the LED branches such that they have a defined ratio with respect to one another in the LED branches. The method is intended to be improved such that it can be carried out economically and with simple means. This is achieved in that one of the LED branches is selected to be the master whose current is utilized as the target specification for the remaining LED branches.The invention further relates to a circuit arrangement for implementing the method according to the invention as well as a lighting unit with such type of circuit arrangement.
