摘要： A heat exchanger according to the invention comprises a heat exchanging ele- ment (101) comprising heat transferring walls for preventing first fluid and second fluid from mixing with each other and for transferring heat from the first fluid to the second fluid. The heat exchanger comprises one or more rooms containing phase change material capable of storing heat energy by changing from the solid state to the liquid state and releasing the heat energy by changing from the liquid state back to the solid state. The heat exchanger further comprises a cooling channel system (104) for third fluid for cooling the phase change material so as to protect the phase change material against overheating. A heat exchanger of the kind de- scribed above can be used for example as a vaporizer of an energy converter based on for example the Organic Rankine Cycle.

摘要： An energy converter based on a thermodynamic energy conversion process comprises an electrical turbo-machine (101) for converting energy contained by vaporized working fluid into electrical energy, a condenser (104) for condensing the vaporized working fluid outputted by the electrical turbo-machine, a vaporizer (105) for receiving a main heat flow from an external heat source and for vaporizing the condensed working fluid, and a feed pump (106) for pumping the condensed working fluid to the vaporizer. The energy converter can be based on for example the Organic Rankine Cycle. The energy converter further comprises a controllable heating device (107) for generating a controllable auxiliary heat flow to the vaporizer so as to at least partly compensate for temporal variations in the main heat flow. Therefore, the energy converter is suitable for being used also with a varying main heat flow which is sometimes unable to maintain the thermodynamic energy conversion process.

摘要： An energy converter comprises an electrical turbo-machine (201) for converting energy contained by vaporized working fluid into electrical energy, a condenser (204) for condensing the vaporized working fluid outputted by the electrical turbo-machine, a condenser tank (205) for storing the condensed working fluid, and a feed pump (206) for pumping the condensed working fluid from the condenser tank to a vaporizer (216). The energy converter can be based on for example the Organic Rankine Cycle. The energy converter further comprises a pumping system (207) for pumping gaseous phase working fluid from the gas-space (208) of the condensation tank to flow through a generator section of the electrical turbo-machine so as to cool at least the rotor of the generator section. Thus, the condenser is utilized not only for the thermodynamic energy conversion process but also for removing heat caused by the power losses of the generator section.

摘要： A high-speed electrical turbo-machine for an Organic Rankine Cycle energy converter is presented. The electrical turbo-machine comprises a stator (101), a rotor (102) for interacting with the stator, and an impeller (103) at an end of the rotor, the impeller being suitable for operating as a turbine for rotating the rotor. The stator comprises a stator core (104) having stator teeth (111, 112) and a stator winding having stator coils (105, 108). The width of each stator coil is one stator slot pitch and each stator coil is arranged to surround only one of the stator teeth so as to minimize the length of the stator end-windings in the axial direction of the rotor. The short end-windings enable the rotor to be shorter, and thus the natural frequencies of the rotor are higher. As a corollary, the critical speeds that excite the natural frequencies of the rotor are higher too.
摘要翻译：提出了一种用于有机朗肯循环能量转换器的高速电动涡轮机。电涡轮机包括定子（101），用于与定子相互作用的转子（102）和在转子的端部处的叶轮（103），叶轮适于作为用于使转子旋转的涡轮机。定子包括具有定子齿（111,112）的定子铁心（104）和具有定子线圈（105,108）的定子绕组。每个定子线圈的宽度是一个定子槽间距，并且每个定子线圈被布置成仅围绕定子齿中的一个，以使定子端绕组在转子的轴向方向上的长度最小化。短端绕组使得转子更短，因此转子的固有频率更高。作为推论，激发转子固有频率的临界速度也较高。
