具体实施方式
现在，将参照附图详细地描述根据本公开的实施例，其示例在附图中示出，其中，相同的标号始终表示相同的组件。
目前，现有小容量直驱风力发电机组，其负荷容量相对小、发热部件相对少，尤其陆上机组基于空间布局的限制及成本的考虑，机组通常采用单个冷却系统运行。当冷却系统出现故障时，风力发电机组需要停机来进行处理。随着单机容量增加，风力发电机组的发热部件的损耗量增加且发热部件的数量增多，因此需要提升冷却系统的可靠性。然而，对于单个冷却系统而言， 一旦出现故障，将会增大整个风力发电机组的维护成本及发电量的损失。
尤其对于海上机组，其维护难度大，并且其具有散热需求的部件的数量有所增加，各个部件的控制工艺及逻辑不同，因此其容错结构及系统布局要求也有所不同。而且，随着机组容量的不断增加，机组本身的损耗随之增加，诸如发电机、轴系、变桨、机舱柜、机舱、变流柜、变压器等发热部件均需进行预定的冷量分配才能实现正常运行，因此冷却系统的构成越来越复杂，且冷却系统的数量不断增加，从而冷却系统需要通过不同形式的容错布局来实现。
因此，基于上述需求，本公开提供了一种新型的冷却系统，该冷却系统可根据待冷却部件的冷却逻辑及工艺要求而实现合理的零部件布局，并且该冷却系统进行了双回路备份冗余设计，因此提高了冷却系统的可靠性。
该冷却系统通过独立的两路冷却回路接入到待冷却部件中，两路冷却回路之间仅传递热量而不存在传质现象。而且，对于不同的待冷却部件的末端结构，该冷却系统可采取不同的接入形式，因此可适合及匹配于不同末端结构的要求。当两路冷却回路中的一个冷却回路出现故障时，可启动另一路冷却回路进行工作，实现两个冷却回路的可容错运行。因此，该冷却系统在满足待冷却部件的散热需求的情况下，能够实现冷却系统的容错性，从而提高冷却系统的可靠性。当该冷却系统应用于风力发电机组时，可确保风力发电机组在一个冷却系统出现故障时仍然正常运行而不停机，从而可减小发电量的损失。
冷却系统可包括热交换器模块、第一冷却回路和第二冷却回路，第一冷却回路和第二冷却回路中的冷却剂可在热交换器模块中与冷却热源(诸如，风力发电机组中的发热部件)的冷却剂进行热交换。这里，为了便于描述，将第一冷却回路和第二冷却回路中的冷却剂分别称作第一冷却剂和第二冷却剂，而将从热源直接吸收热量的冷却剂称作第三冷却剂。
热交换器模块至少包括彼此独立的第一通道和第二通道，第一冷却回路与热交换器模块的第一通道连接，第二冷却回路与热交换器模块的第一通道连接。第一冷却回路中的第一冷却剂和/或第二冷却回路中的第二冷却剂能够流经热交换器模块的第一通道，以用于与流经热交换器模块的第二通道的第三冷却剂热交换。
如此，通过第一冷却剂和/或第二冷却剂分别与第三冷却剂之间的热交换， 可实现对第三冷却剂的冷却。而且，第一冷却回路和第二冷却回路均可单独运行，一旦其中一者出现故障，可以随时启动另一个冷却回路，因此可实现冷却系统的容错运行，从而可确保风力发电机组正常运行而不停机。当然，本公开的冷却系统不限于应用于风力发电机组，其也可应用于其他组件系统的各种待冷却部件。
下面，将参照图1至图4描述根据本公开的冷却系统的具体构成。
图1是根据本公开的第一实施例的冷却系统的示意性框图。
如图1所示，冷却系统包括位于左侧的第一冷却回路、位于右侧的第二冷却回路以及包括第一热交换器8和第二热交换器8’的热交换器模块。第一冷却回路与第二冷却回路的构成可基本相同，第一热交换器8和第二热交换器8’的构成也可基本相同。
第一热交换器8和第二热交换器8’中的每者可至少具有彼此独立的第一通道和第二通道，第一冷却回路中的第一冷却剂能够流经第一热交换器8的第一通道，以用于与流经第一热交换器8的第二通道的第三冷却剂热交换，第二冷却剂能够流经第二热交换器8’的第一通道，以用于与流经第二热交换器8’的第二通道的第三冷却剂热交换。即，第一冷却剂和第二冷却剂能够分别在第一热交换器8和第二热交换器8’中与第三冷却剂热交换。当第一冷却回路和第二冷却回路中的一者出现故障时，另一个冷却回路可继续运行，因此可实现不停机运行。第一冷却回路和第二冷却回路可采用全负荷容错(一用一备)，或可通过两路共同运行实现全负荷运行。
由于第一冷却回路和第一热交换器8的构成及彼此之间的连接与第二冷却回路和第二热交换器8’的构成及彼此之间连接相似，因此下面将以第一冷却回路和第一热交换器8为例进行描述。
如图1所示，第一冷却回路可包括循环泵1，循环泵1的出口通过进液管路2连接到第一热交换器8的第一通道的第一端(具体地，第一进液口8a)，第一热交换器8的第一通道的第二端(具体地，第一出液口8b)可通过出液管路12连接到循环泵1。如此，在循环泵1的作用下，第一冷却剂可在第一冷却回路中循环流动。第一冷却回路上还可包括第一散热器27，用于对第一冷却剂进行降温。第一散热器27可以为空冷散热器。
第一冷却剂与第三冷却剂通过第一热交换器8进行热交换，第三冷却剂在第一热交换器8的第二通道、第三冷却剂供应管路18和第三冷却剂回流管 路15内循环。第三冷却剂供应管路18的第一端连接到第一热交换器8的第二通道的第一端(具体地，第二进液口8c)，并且第三冷却剂回流管路15的第一端连接到第一热交换器8的第二通道的第二端(具体地，第二出液口8d)。第三冷却剂可在从热源设备吸热后，通过第三冷却剂供应管路18流入到第一热交换器8的第二通道，并且可在与第一冷却剂完成热交换后，通过第三冷却剂回流管路15流回到热源设备中，从而持续不断地对热源设备进行降温。
具体地，在循环泵1的作用下，第一冷却剂通过进液管路2进入到第一热交换器8的第一通道内，同时第三冷却剂通过第三冷却剂供应管路18进入到第一热交换器8的第二通道内，第一冷却剂和第三冷却剂可在第一热交换器8内实现热交换。优选地，第一冷却剂和第三冷却剂可在第一热交换器8中逆向流动。在完成热交换后，第一冷却剂在流经第一热交换器8的第一通道后在循环泵1的作用下通过出液管路12流回到第一散热器27内，通过第一散热器27降温后再次进入第一热交换器8的第一通道内，进行下一次循环。流经第一热交换器8的第二通道的第三冷却剂可在动力源作用下通过第三冷却剂回流管路15流回到热源设备中。
可选地，进液管路2上可设置有第一过滤器6，例如，第一过滤器6可设置在循环泵1与第一热交换器8的第一进液口8a之间，以提高流入第一热交换器8内的第一冷却剂的洁净度，从而避免管路堵塞。另外，第一过滤器6的入口侧可设置有第一压力变送器5，并且第一过滤器6的出口侧可设置有第二压力变送器7，用于监测第一过滤器6的运行状态。例如，当第一压力变送器5与第二压力变送器7之间的压差△P1达到预先设置的压差△P1时，需要更换第一过滤器6。另外，第一热交换器8的出口侧可设置有第三压力变送器9，用于监测第一热交换器8的第一通道堵塞情况。例如，当第二压力变送器7与第三压力变送器9之间的压差△P2达到预先设置的压差△P2时，需要对第一热交换器8的第一通道进行疏通。
此外，进液管路2上可设置有第一温度传感器3，出液管路12上可设置有第二温度传感器10，用于感测进出第一热交换器8的第一冷却剂的温度，以基于所感测的温度获知第一冷却剂与第三冷却剂的热交换状态。另外，进液管路2上还可设置有第一开关阀4，和/或出液管路12上可设置有调节阀11。通过设置第一开关阀4和/或调节阀11，在冷却系统进行维护或更换零部件时，可通过关闭第一开关阀4和/或调节阀11而实现局部管路截断，因此 便于进行相应的维护和更换操作。
与第一冷却回路的构成类似，第三冷却剂供应管路18上可设置有第二过滤器19，用于提高流入第一热交换器8的第二通道的第三冷却剂的洁净度。第二过滤器19的两侧可设置有第四压力变送器17和第五压力变送器21，用于监测第二过滤器19的运行状态。例如，当第四压力变送器17与第五压力变送器21之间的压差△P3达到预先设置的压差△P3时，需要更换第二过滤器19。第三冷却剂回流管路15上可设置有第三温度传感器14，以根据第三温度传感器14感测的温度值调节第一冷却回路中的调节阀11的开度，从而确保冷却过程中第三冷却剂的温度不低于待冷却部件的工艺要求所设置的温度。此外，第三冷却剂回流管路15上还可设置有第六压力变送器16，用于结合第四压力变送器17所感测的压力值来监测第一热交换器8的第二通道的堵塞情况。此外，第三冷却剂供应管路18上可设置有第二开关阀20和/或第三冷却剂回流管路15上可设置有第三开关阀13，以在冷却系统进行维护或更换零部件时，关闭第二开关阀20和/或第三开关阀13而实现局部管路截断，因此便于进行相应的维护和更换操作。
优选地，第一热交换器8可包括板式热交换器，板式热交换器可包括换热翅片。因此，在第一冷却剂与第三冷却剂热交换时，第一热交换器8的换热翅片可同时与外部空气进行热交换，从而可进一步增强对第三冷却剂进行冷却的效率。
类似地，第二热交换器8’也可具有第一进液口8’a、第一出液口8’b、第二进液口8’c和第二出液口8’d，第二热交换器8’与第二冷却回路、第三冷却剂供应管路和第三冷却剂回流管路之间的连接与第一热交换器8与第一冷却回路、第三冷却剂供应管路和第三冷却剂回流管路之间的连接类似，在此不再赘述。
图2是根据本公开的第二实施例的冷却系统的示意性框图。
第二实施例的冷却原理与第一实施例的冷却原理相似，不同之处在于：设置了连接第一热交换器8和第二热交换器8’的连接管路22。
与第一实施例中的第二热交换器8’不同，如图2所示，第一实施例中的第二热交换器8’的第二进液口8’c在第二实施例中用作第二出液口并且与第三冷却剂回流管路15连接，而第一实施例中的第二热交换器8’中的第二出液口8’d在第二实施例中用作第二进液口并且通过连接管路22与第一换热器8 的第二出液口8d连接，因此减少了第三冷却剂供应管路18和第三冷却剂回流管路15的布局和数量。即，通过设置连接管路22，有效地实现了第一热交换器8的第二通道和第二热交换器8’的第二通道的串联，由此减少了一路第三冷却剂供应管路18和第三冷却剂回流管路15，从而简化了管路的布局。
在第一热交换器8和第二热交换器8’通过连接管路22串联的情况下，第三冷却剂供应管路18的第一端可连接到第一热交换器8的第二通道的第二端(即，第二进液口8c)，第三冷却剂回流管路15的第一端可连接到第二热交换器8’的第二通道的第二端(即，第二出液口)。当然，第三冷却剂供应管路18和第三冷却剂回流管路15的位置可以互换。
冷却系统的其余部件的构造和布局与第一实施例中的部件的构造和布局相似，因此不再赘述。
冷却系统采用上述的布局方式，不仅可以实现第一冷却回路与第二冷却回路的独立运行，当其中一者出现故障后，启动另一个冷却回路实现容错运行，保证对发热部件的冷却效率；还可以进一步简化布局的管路和器件，在需要紧凑布局空间的情况下，具有一定的优势。
图3是根据本公开的第三实施例的冷却系统的示意性框图。
第三实施例的冷却原理与第一实施例的冷却原理相似，不同之处在于：该冷却系统的热交换器模块使用三通道热交换器23，因此可进一步有效地简化零部件的设置及布局。在冷却系统中的一路冷却回路出现故障后，冷却系统中的另一冷却回路仍能够正常运行。
在第三实施例中，三通道热交换器23可包括相互独立的第一流道、第二流道和第三流道。第一流道可连通第一进液口23a和第一出液口23b，第二流道可连通第二进液口23c和第二出液口23d，第三流道可连通第三进液口23e和第三出液口23f。第一冷却回路可与三通道热交换器23的第一流道相连，第二冷却回路可与三通道热交换器23的第三流道相连，并且第三冷却剂供应管路18和第三冷却剂回流管路15可分别连接在三通道热交换器23的第二流道的两端。如此，第一冷却回路中的第一冷却剂能够流经三通道热交换器23的第一流道且第二冷却回路中的第二冷却剂能够流经三通道热交换器23的第三流道，以与流经三通道热交换器23的第二流道的第三冷却剂热交换。
冷却系统的其余部件的构造和布局与第一实施例中的部件的构造和布局相似，因此不再赘述。
冷却系统采用上述的布局方式，不仅可以实现第一冷却回路与第二冷却回路的独立运行，当其中一者出现故障后，启动另一个冷却回路实现容错运行，保证对发热部件的冷却效率；还进一步将两个换热器集成为一个换热器，简化布局的管路和器件，能进一步在有限的空间内实现两个冷却回路的冗余布局。
图4是根据本公开的第四实施例的冷却系统的示意性框图。
第四实施例的冷却原理与第一实施例的冷却原理相似，不同之处在于：第一冷却回路和第二冷却回路与热交换器模块的布局与第一实施例中的相应布局不同。
如图4所示，第一冷却回路和第二冷却回路以并联连接的方式与热交换器模块的第一通道连接。在本实施例中，热交换器模块可以为单个第一热交换器8，也可以是多个串联连接的第一热交换器8。第一冷却回路和第二冷却回路以并联连接的方式与第一热交换器8连接。
具体地，第一热交换器8包括第一进液口8a、与第一进液口8a连接的进液总管24、第一出液口8b以及与第一出液口8b连接的出液总管25，第一冷却回路和第二冷却回路以并联连接的方式连接在第一热交换器8的进液总管24和出液总管25之间。也就是说，进液总管24和出液总管25可实现第一冷却回路和第二冷却回路的汇集及分流。这样就可以合并两个冷却回路的一部分管路，对管路进一步简化设置，实现整体布局的紧凑性。
第一冷却回路和第二冷却回路中的至少一个上可设置有止回阀26，例如，可设置在进液管路2上，止回阀26可具有单向导通功能。当第一冷却回路和第二冷却回路中的一个冷却回路出现故障而停止运行时，第一冷却回路和第二冷却回路中的另一冷却回路能够正常运行，且另一冷却回路中的冷却剂通过进液总管24流入到第一热交换器8内。对于故障停机的冷却回路，由于设置了止回阀26，因此正常运行的冷却回路中的冷却剂不能进入到该故障的冷却回路中，确保了在单个小容量换热器设置的情况下的冷却效率。由此，在确保冷却系统的布局被大大简化的同时，也能够实现冷却系统的容错运行。
在本实施例中，进液管路2包括进液总管24和连接在循环泵1与第一热交换器8之间的管路，出液管路12包括出液总管25和连接在循环泵1与第一热交换器8之间的管路。此外，在图4中，第一过滤器6和第二压力变送器7设置在进液总管24上，调节阀11设置在出液总管25上，但不限于此。 也就是说，第一冷却回路和第二冷却回路上的相应器件的布局可根据实际情况设计，其并不局限于图中所示出的示例。
根据本公开的冷却系统，通过双冷却回路设计，可提高冷却系统的可靠性，因此在应用于风力发电机组时，可减少风力发电机组的停机问题，从而可提高风力发电机组的可利用率。此外，根据本公开的冷却系统，通过设置具有换热翅片的热交换器模块，可进一步提高冷却系统的冷却效率。此外，根据本公开的冷却系统，双冷却回路的容错结构布局简单紧凑，易于在有限空间内实现和维护。此外，根据本公开的冷却系统，可根据待冷却部件的冷却逻辑及工艺要求而实现合理的零部件布局。
虽然上面已经详细描述了本公开的实施例，但本领域技术人员在不脱离本公开的精神和范围内，可对本公开的实施例做出各种修改和变形。但是应当理解，在本领域技术人员看来，这些修改和变形仍将落入权利要求所限定的本公开的实施例的精神和范围内。
