摘要： The present invention relates to a heat sink for instance for use in a remote radio unit comprising a plurality of fins (8, 9, 10) arranged such that channels (11, 12, 13) are formed between adjacent fins, said channels (11, 12, 13) comprising an air inflow and an air outflow, wherein the heat sink comprises at least two groups (5, 6, 7) of fins (8, 9, 10) arranged such that the air inflow of the channels of a first of said groups (5) is located differently from the air outflow of the channels of the remaining of said groups (6, 7). The invention furthermore relates to a method of cooling a heat- generating device, such as a remote radio unit, the method comprising providing at least two groups of air flow channels in thermal contact with said heat- generating device, each channel having an air inflow region and an air outflow region, wherein the air inflow regions of the channels of the first group are located differently from the air outflow regions of the channels of the remaining groups, such that hot air leaving through the air outflow regions of said remaining groups is prevented from entering the channels of the first group through the respective air inflow regions of the first group.
摘要翻译：散热器技术领域本发明涉及一种散热器，例如用于远程无线电单元，包括多个散热片（8,9,10），其布置成使得在相邻散热片之间形成通道（11,12,13），所述通道（11 ，12,13），其包括空气流入和空气流出，其中所述散热器包括至少两组散热片（8,9,10），所述散热片（8,9,10）布置成使得所述散热片所述组（5）中的第一位置与所述组（6,7）中剩余的通道的空气流出不同。本发明还涉及一种冷却诸如远程无线电单元的发热装置的方法，所述方法包括提供与所述发热装置热接触的至少两组空气流动通道，每个通道具有空气流入区域和空气流出区域，其中，所述第一组的通道的空气流入区域与其余组的通道的空气流出区域不同，使得通过所述剩余组的空气流出区域流出的热空气为防止通过第一组的各个空气流入区域进入第一组的通道。
