朗肯循环以及在朗肯循环中使用的热交换器
摘要：
本发明提供一种朗肯循环，其避免冷媒的热分解，并提高与冷媒的热交换量。该朗肯循环（31）包含：热交换器（92、111），其将发动机的废热向第1冷媒回收；膨胀机（37），其使用该热交换器出口的第1冷媒而产生动力；冷凝器（38），其使从该膨胀机排出的第1冷媒凝结；以及冷媒泵（32），其将由该冷凝器凝结而得到的第1冷媒向上述热交换器供给，热交换器具有：第1热交换器（92），其将排气的热量向第2冷媒中回收；以及第2热交换器，其具有第2冷媒通路（112）以及第1冷媒通路（113）与冷却水通路（114），它们用于在该第2冷媒与第1冷媒以及发动机的冷却水之间进行热交换。
摘要（英）：

The present invention provides a Rankine cycle, which can avoid thermal decomposition of refrigerant and can increase the heat exchange amount of the refrigerant. The Rankine cycle (31) comprises heat exchangers (92, 111) for recovering the waste heat of an engine to a first refrigerant; an expansion machine (37) which can use the first refrigerant output by the heat exchanger to generate power; a condenser (38) for condensing the first refrigerant discharged by the expansion machine; and a refrigerant pump (32) which can supply the first refrigerant obtained through the condensing of the condenser to the heat exchanger. The heat exchanger is provided with a first heat exchanger (92) for recovering the discharge heat to a second refrigerant, and a second heat exchanger comprising a second refrigerant passage (112), a first refrigerant passage (113) and a cooling water passage (114), which are used for heat exchange between the first and second refrigerants and the cooling water of the engine.
