Structural frame cooling manifold

A variable speed drive includes a converter connected to an AC power source, a DC link connected to the converter, and an inverter connected to the DC link. The inverter converts DC voltage into an output AC power having a variable voltage and frequency. The inverter includes at least one power electronics module and associated control circuitry; a heat sink in thermal communication with the power electronics module and in fluid communication with a manifold. The manifold includes a tubular member having at least one vertical member portion and at least one horizontal member portion in fluid communication. A plurality of ports conduct cooling fluid into and out of the manifold. A bracket attaches the manifold to a structural frame. Brackets are provided for attachment of power electronics modules to the manifold. 种变速驱动装置包括连接至交流电源的转换器、连接至所述转换器的直流环节、以及连接所述直流环节的逆变器。所述逆变器将直流电压转换成具有可变电压和频率的输出交流电。所述逆变器包括至少个电力电子器件模块和相关联的控制电路；与所述电力电子器件模块热连通并且与歧管流体连通的散热器。所述歧管包括具有流体连通的至少个竖直构件部和至少个水平构件部的管状构件。多个端口将冷却流体导入和导出所述歧管。托架将所述歧管联接
