This is the same arrangement found in an old-fashioned steam radiator, in which the coiled pipes pass heat back and forth as water courses through them.

这个结构与老式蒸汽暖气片相同，水流经散热器时，热量通过盘管来回输送。

The solution pumps hot water from a power plant through underground pipes to heat exchangers which heat up water in the secondary distribution network and feed it into consumer radiator systems.

该解决方案把热水从发电厂抽上来，通过地下管道至热交换器，热交换器在二级分配网络上将水加热，然后将它流入用户的散热器系统。

High demand for water amid the heat wave and problems with soil shrinking as the ground warms has resulted in burst pipes and low water pressure in Oklahoma City, prompting officials to issue mandatory water-use restrictions for the first time in at least a decade, according to utilities department spokeswoman Debbie Ragan.

In icy Tomsk, the potential for heat loss is even worse: astonishingly, the pipes that carry warm water around the district heating network of Seversk and Tomsk are completely uninsulated.
