Abstract
A method and means for arranging heat transport, i.e. cooling or heating, of electrical components, are disclosed. Embodiments of the invention show how one or several flexible tubes (,) are arranged in connection with units (,) comprising electrical components. The units (,) can be enclosed in cabinets (,). The tube (,) can be arranged in a zigzag pattern around the units (,) and pressurized by a fluid from a combined pump and heat exchanger (,). The pressure expands the wall of the tube (,), thus creating thermal contact with the units (,). By flowing fluid in the tube (,) heat can be transported from or to the units (,). Tubes (,) arranged in several cabinets (,) can be connected, either in series or in parallel.
