技术领域
本申请实施例涉及制冷设备技术领域，特别涉及一种间接蒸发冷却装置。
背景技术
间接蒸发冷却装置是通过非直接接触式换热芯将直接蒸发冷却得到的湿空气的冷量传递给待处理空气，以实现空气等湿降温的制冷装置，因该间接蒸发冷却装置能够实现待处理空气的等湿降温，同时具有节能的特点，被广泛应用在数据机房、商场等场所。
间接蒸发冷却装置包括换热芯、过滤网和湿膜，换热芯用于实现室内空气与室外空气之间的间接换热，从而降低室内空气的温度。过滤网和湿膜均设置在换热芯的室外进风口处，其中，过滤网位于室外进风口的最外侧，与室外环境直接接触，其用于过滤室外空气中的柳絮以及沙尘等杂物，湿膜设置在过滤网与室外进风口之间，该湿膜用于冷却经过滤网过滤后的室外空气，以增大进入换热芯内的室外空气与室内空气之间的温度差，从而提高换热效率。
然而，传统的间接蒸发冷却装置中，过滤网极易被室外空气中的杂物堵塞，而堵塞后的过滤网不易清理，增大了后期维护难度以及维护成本。
发明内容
本申请实施例提供了一种间接蒸发冷却装置，以解决传统的间接蒸发冷却装置中，过滤网被柳絮或者沙尘等杂物堵塞而不易清理，从而增大了间接蒸发冷却装置的后期维护难度以及维护成本的问题。
本申请实施例提供一种间接蒸发冷却装置，包括换热芯、湿膜、过滤网及储水装置；
间接蒸发冷却装置还包括室外进风过渡段，室外进风过渡段的进风端与室外环境连通，室外进风过渡段的出风端与换热芯的室外空气进风口连通；
湿膜和过滤网均设置在室外进风过渡段内，且过滤网位于湿膜与室外空气进风口之间，储水装置与湿膜的进水口连通，用于冲洗湿膜。
本申请实施例提供的间接蒸发冷却装置，通过在室外进风过渡段设置过滤网和湿膜，并将湿膜设置在过滤网背离换热芯的室外空气进风口的一侧，这样，可先通过湿膜对室外空气中尺寸较大的杂物例如柳絮以及大颗粒沙尘进行过滤，再经过滤网对细小杂物例如小颗粒沙尘进行精细过滤，不仅保证进入换热芯内的室外空气的清洁度，而且避免了过滤网短周期脏堵，延长了过滤网的使用寿命，降低了对过滤网的维护成本，同时而且因湿膜的过滤精度较过滤网低，从而也延长了湿膜的维护周期。另外，通过在湿膜的进水口处连通储水装置，这样，在湿膜出现堵塞的情况时，可直接通过储水装置向湿膜提供水源，对湿膜进行冲洗，从而简化了对湿膜的维护工序，降低了间接蒸发冷却装置后期的维护难度以及成本。另外，对湿膜冲洗的过程也是再次加湿湿膜的过程，从而合理利用了水资源。

水箱上具有补水口，储水装置与补水口连通，水箱上还具有出水口，出水口与湿膜的进水口连通，水泵设置在水箱与湿膜的进水口连通的管路上。
本申请实施例通过将水箱连通至湿膜的进水口，这样，当需要对湿膜进行清洗时，可通过水泵将水箱内的水打入湿膜内，对湿膜上的杂物例如柳絮以及大颗粒沙尘进行冲洗，冲洗后的水直接排入水箱内，可供再次冲洗使用，不仅保证了对湿膜的清理及时性和方便性，而且水箱内的水可循环使用，也进一步降低了对水资源的浪费。另外，通过将储水装置与水箱连通，这样当水箱内的水无法继续冲洗湿膜时，可随时排出，并通过该储水装置随时为水箱内补充清洁水，保证水箱内的循环水的清洁度，使其始终满足湿膜的加湿与清洗要求。
在一种可选地实现方式中，间接蒸发冷却装置还包括液位传感器；

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
间接蒸发冷却装置是通过非直接接触式换热芯将直接蒸发冷却得到的湿空气的冷量传递给待处理空气，以实现空气等湿降温的制冷装置，因该间接蒸发冷却装置能够实现待处理空气的等湿降温，同时具有节能的特点，被广泛应用在数据机房、商场等场所。
以数据机房为例，实际应用中，数据机房内通常安装有基站设备、电源设备、蓄电池、传输设备等，为了保证基站设备等能够在正常温度下稳定工作，在数据机房内可以安装间接蒸发冷却装置，通过该间接蒸发冷却装置对数据机房内的空气进行散热，以控制户外机柜或者机房内部的温度，从而保证数据机房内的基站设备、电源设备等的正常工作，防止数据机房内的设备受损。
传统技术中，间接蒸发冷却装置包括换热芯、过滤网以及湿膜。其中，该换热芯内具有相互独立的室内空气循环通道和室外空气循环通道，该室内空气循环通道的两端通过室内空气进风口和室内空气出风口分别与室内环境连通，以使该室内空气循环通道与室内环境内空气能够循环流通。室外空气循环通道的两端分别通过室外空气进风口和室外空气出风口分别 与室外环境连通，以使该室外空气循环通道与室外环境内的空气能够循环流通。
实际应用中，在换热芯的室外进风口与室外环境之间具有室外进风过渡段，例如，间接蒸发冷却装置具有室外进风口，室外进风过渡段的一端与室外进风口连通，以保证室外进风过渡段与室外环境连通，室外进风过渡段的另一端与换热芯的室外空气进风口连通，以保证室外进风过渡段与换热芯内的室外空气循环通道连通，这样，便可实现室外空气循环通道与室外环境之间的连通。
间接蒸发冷却装置的湿膜和过滤网均设置在室外进风过渡段内，且湿膜位于过滤网与换热芯的室外空气进风口之间，也即是说，过滤网位于靠近室外进风口的位置，湿膜位于过滤网背离室外进风口的一侧，例如，过滤网位于室外进风口处，湿膜位于换热芯的室外空气进风口处。
间接蒸发冷却装置对数据机房进行散热时，室内的热空气通过室内空气进风口进入换热芯的室内空气循环通道内，室外空气先通过室外进风口进入室外进风过渡段，先通过过滤网对该室外空气中的杂物例如柳絮以及沙尘颗粒等进行过滤，继而通过湿膜对过滤后的室外空气进行加湿降温，降温后的室外空气随后经换热芯的室外空气进风口进入室外空气循环通道内，与室内空气循环通道内的高温空气进行热交换，降温后的室内空气随后经室内空气出风口进入室内即数据机房内部，对数据机房内的蓄电池等设备进行散热，室外空气循环通道内的室外空气受热后从室外空气出风口排出至室外即数据机房外部。
其中，因过滤网的过滤精度较湿膜大，且过滤网位于靠近室外环境的一侧，则该过滤网起到精细过滤室外空气的作用，湿膜仅起到加湿并降低室外空气温度的作用。
春季时节，室外空气中弥漫有大量的柳絮以及沙尘等杂物，尤其是在我国西北部地区，室外空气中的柳絮以及沙尘更多，因过滤网的过滤效率较高，使得该过滤网极易被室外空气中的柳絮以及沙尘等杂物堵塞，而脏堵后的过滤网需要人力进行维护，维护难度大，通常会直接更换新的过滤网，这就增大了间接蒸发冷却装置的后期维护难度以维护成本。
本申请实施例提供一种间接蒸发冷却装置，通过在室外进风过渡段设置过滤网和湿膜，并将湿膜设置在过滤网背离换热芯的室外空气进风口的一侧，这样，可先通过湿膜对室外空气内尺寸较大的杂物例如柳絮以及大颗粒沙尘进行过滤，再经过滤网对尺寸较小的杂物例如小颗粒沙尘进行精细过滤，不仅保证进入换热芯内的室外空气的清洁度，而且避免了过滤网短周期脏堵，延长了过滤网的使用寿命，降低了对过滤网的维护成本，同时而且因湿膜的过滤精度较过滤网低，从而也延长了湿膜的维护周期。另外，通过在湿膜的进水口处连通储水装置，这样，在湿膜出现堵塞的情况时，可直接通过储水装置向湿膜提供水源，对湿膜进行冲洗，从而简化了对湿膜的维护工序，降低了间接蒸发冷却装置后期的维护难度以及成本。另外，对湿膜冲洗的过程也是再次加湿湿膜的过程，从而合理利用了水资源。
以下通过几个实施例并结合附图对本申请实施例的间接蒸发冷却装置的具体结构进行详细描述。
实施例一
图1是本申请实施例提供的间接蒸发冷却装置的第一种结构示意图。参照图1所示，本申请实施例提供一种间接蒸发冷却装置10，包括换热芯100、湿膜300、过滤网200及储水装置400。
其中，换热芯100内具有相互独立的室内空气循环通道和室外空气循环通道，该室内空气循环通道的两端分别通过室内空气进风口120和室内空气出风口130分别与室内环境连通，以使该室内空气循环通道与室内环境内空气能够循环流通。
实际应用中，间接蒸发冷却装置10还包括室内进风过渡段110和室内出风过渡段140，其中，间接蒸发冷却装置10还包括室内进风口111和室内出风口141。
室内进风口111与室内环境连通，室内进风过渡段110的进风端与室内进风口111连通，以使室内进风过渡段110与室内环境连通，室内进风过渡段110的出风端与换热芯100的室内空气进风口120，以使室内进风过渡段110与室内空气循环通道连通，这样，室内环境便通过室内进风过渡段110与换热芯100的室内空气循环通道连通，使得室内环境中的空气即室内空气101依次通过室内进风口111、室内进风过渡段110及室内空气进风口120进入室内空气循环通道内。
其中，室内进风口111可以设置在室内进风过渡段110与室内环境连通的任意一个侧壁上，例如，该室内进风口111可以设置在间接蒸发冷却装置10设有室内进风过渡段110的顶壁上。
另外，室内出风口141与室内环境连通，室内出风过渡段140的进风端与换热芯100的室内空气出风口130连通，使得该室内出风过渡段140与室内空气循环通道连通，室内出风过渡段140的出风端与室内出风口141连通，使得该室内出风过渡段140与室内环境连通，这样，换热芯100的室内空气循环通道便通过室内出风过渡段140与室内环境连通，从而使得室内空气循环通道内的空气依次通过室内空气出风口130、室内出风过渡段140以及室内出风口141进入室内环境中。其中，室内出风口141可以设置在室内出风过渡段140与室内环境连通的任意一个侧壁上，例如，该室内进风口111可以设置在间接蒸发冷却装置10设有室内出风过渡段140的侧壁上。
基于上述可知，室内进风过渡段110、室内空气101循环通道及室内出风过渡段140共同形成与室内空气循环流通的室内空气流动通道。实际应用中，可以在室内出风过渡段140设置风扇900，以促进间接蒸发冷却装置10的室内空气流动通道与室内环境中空气的流动效率，从而提高换热效率。
本申请实施例中，室外空气循环通道的两端分别通过室外空气进风口160和室外空气出风口170与室外环境连通，以使该室外空气循环通道与室外环境内的空气能够循环流通。
实际应用中，间接蒸发冷却装置10还包括室外进风过渡段150和室外出风过渡段180。
其中，间接蒸发冷却装置10具有室外进风口151，室外进风口151与室外环境连通，室外进风过渡段150的进风端与室外进风口151连通，以保证室外进风过渡段150与室外环境连通，室外进风过渡段150的出风端与换热芯100的室外空气进风口160连通，以保证室外进风过渡段150与换热芯100内的室外空气循环通道连通，这样，室外环境便通过室外进风过渡段150与换热芯100的室内空气循环通道连通，使得室外环境中的空气即室外空气102依次通过室外进风口151、室外进风过渡段150及室外空气进风口160进入室外空气循环通道内。
其中，室外进风口151可以设置在室外进风过渡段150与室外环境连通的任意一个侧壁上，例如，该室外进风口151可以设置在间接蒸发冷却装置10设有室外进风过渡段150的侧壁上。
另外，间接蒸发冷却装置10具有室外出风口181，室外出风口181与室外环境连通，室外出风过渡段180的进风端与换热芯100的室外空气出风口170连通，以保证室外出风过渡段180与换热芯100的室外空气循环通道连通，室外出风过渡段180的出风端与室外出风口181连通，以保证室外出风过渡段180与室外环境连通，这样，换热芯100的室外空气循环通道便通过室外出风过渡段180与室外环境连通，从而使得室外空气循环通道内的空气依次 通过室外空气出风口170、室外出风过渡段180以及室外出风口181进入室外环境中。
其中，室外出风口181可以设置在室外出风过渡段180与室外环境连通的任意一个侧壁上，例如，该室外进风口151可以设置在间接蒸发冷却装置10设有室外出风过渡段180的侧壁上。
基于上述可知，室外进风过渡段150、室外空气循环通道及室外出风过渡段180共同形成与室外空气102循环流通的室外空气流动通道。
实际应用中，可以在室外出风过渡段180设置风扇900，以促进间接蒸发冷却装置10的室外空气流动通道与室外环境中空气的流动效率，从而提高换热效率。
需要说明的是，换热芯100的结构可为多种，例如，该换热芯100可以是一体成型的一体件，在该一体件内具有相互独立且交叉设置的多个管路，其中沿第一方向延伸的一个或多个管路形成室内空气循环通道，沿第二方向延伸的一个或多个管路形成室外空气循环通道，且第一方向和第二方向之间具有一定夹角。这样，室内空气循环通道内的空气可通过相邻管壁与室外空气循环通道内的空气进行热交换。本申请实施例不对换热芯100的具体结构进行限制，具体可直接参照现有的换热芯。
本申请实施例的湿膜300和过滤网200均设置在室外进风过渡段150内，其中，过滤网200位于湿膜300与换热芯100的室外空气进风口160之间，也即是说，湿膜300靠近室外进风过渡段150的进风端设置，过滤网200靠近换热芯100的室外空气进风口160设置，例如，该湿膜300设置在室外进风过渡段150的进风端，过滤网200设置在换热芯100的室外空气进风口160处。
本申请实施例中，湿膜300为一体成型的一体件，这样不仅提高了该湿膜300的结构稳定性，而且使得该湿膜300在室外进风口151过渡段中的装配更加方便快捷。
可以理解的是，本申请实施例的湿膜300以及过滤网200可通过抵接、卡接、粘接、螺钉连接等方式固定在间接蒸发冷却装置10位于室外进风过渡段150的内壁上，本申请实施例具体不对湿膜300以及过滤网200的固定方式进行限制。
本申请实施例的间接蒸发冷却装置10对数据机房等待降温场所进行散热时，室内的热空气依次通过室内进风口111、室内进风过渡段110以及室内空气进风口120进入换热芯100的室内空气循环通道内，室外空气102先通过室外进风口151进入室外进风过渡段150，继而通过湿膜300对室外空气102中尺寸较大的杂物例如柳絮及大颗粒沙尘等进行过滤，同时，该室外空气102与湿膜300中的冷水进行热交换，以加湿室外空气102并降低室外空气102的温度，随后过滤网200对加湿并降温后的室外空气102中的尺寸较小的杂物例如小颗粒沙尘进行精细过滤，过滤后的室外空气102接着经换热芯100的室外空气进风口160进入室外空气循环通道内，与室内空气循环通道内的高温空气进行热交换，降温后的室内空气101依次经室内空气出风口130、室内出风过渡段140及室内出风口141进入室内例如数据机房内部，对数据机房内的蓄电池等设备进行散热，室外空气循环通道内的室外空气102受热后依次经室外空气出风口170、室外出风过渡段180及室外出风口181排出至室外例如数据机房外部。
其中，湿膜300对室外空气102的加湿降温过程具体为：因室外空气102的温度较湿膜300内的水高，则室外空气102将热量传递至湿膜300内的冷水中，使得该冷水蒸发为水蒸汽，并与室外空气102进行混合，从而实现室外空气102的加湿以及降温作用。降温后的室外空气102增大了与室内空气101之间的温度差，从而提高了间接蒸发冷却装置10对室内空气101的散热效率。
可以理解的是，湿膜300设置在过滤网200背离换热芯100的室外空气进风口160的一侧，且该湿膜300上具有过滤孔，且该过滤孔大于过滤网200的过滤孔，也即是说，该湿膜300的过 滤效率低于过滤网200的过滤效率，湿膜300先对室外空气102中尺寸较大的杂物例如柳絮或大颗粒沙尘进行过滤，初步过滤后的室外空气102再经过滤网200进行精细过滤，即通过该过滤网200过滤室外空气102中的细小杂物例如小颗粒沙尘，这样，不仅保证进入换热芯100内的室外空气102的清洁度，而且避免了过滤网200短周期脏堵，延长了过滤网200的使用寿命，降低了对过滤网200的维护成本，同时而且因湿膜300的过滤精度较过滤网200低，从而也延长了湿膜300的维护周期。
本申请实施例中，湿膜300以及过滤网200的具体结构可直接参照传统的结构，此处不再赘述。
本申请实施例的储水装置400与湿膜300的进水口连通，用于冲洗湿膜300。例如，因长期过滤尺寸较大的杂物例如柳絮或大颗粒沙尘等，使得该湿膜300不可避免地会发生脏堵，而当该湿膜300被柳絮或者大颗粒沙尘等杂物堵塞时，可导通储水装置400与湿膜300之间的管路，使得储水装置400内的水进入湿膜300内，对湿膜300中的杂物进行冲洗，从而使堵塞的湿膜300快速疏通。
本申请实施例通过在湿膜300上连通储水装置400，以在湿膜300发生堵塞时，通过冲洗湿膜300，以疏通湿膜300内的过孔，简化了对湿膜300的维护工序，降低了间接蒸发冷却装置10后期的维护难度以及成本。
另外，通过储水装置400向湿膜300提供水源，以冲洗湿膜300，此过程不仅起到疏通湿膜300作用，确保室外空气102能够通过湿膜300顺利进入换热芯100内，也保证湿膜300能够对室外空气102中的大尺寸杂物进行过滤，而且冲洗湿膜300的过程也是再次加湿湿膜300的过程，从而在保证湿膜300对室外空气102进行加湿降温的同时，合理利用了水资源。
参照图1所示，本申请实施例的间接蒸发冷却装置10还可以包括水阀500，该水阀500设置在储水装置400与湿膜300的进水口连通的管道上，这样，当需要对湿膜300进行清洗维护时，可打开水阀500，使得储水装置400内的水通过湿膜300的进水口进入湿膜300内部，完成对大尺寸杂物的冲洗过程。
本申请实施例通过在储水装置400与湿膜300的进水口连通的管道上设置水阀500，以控制对湿膜300的冲洗以及加湿过程，减小水资源的浪费，同时保证湿膜300的性能不受影响。
具体设置时，该水阀500可以为开关阀，也可以为流量调节阀，例如，当需要加湿湿膜300时，可通过流量调节阀调小储水装置400进入湿膜300内的水流量，以避免对湿膜300的结构造成损坏，同时便于控制加湿程度。当湿膜300堵塞严重时，可通过流量调节阀调大储水装置400进入湿膜300内的水流量，以提高对湿膜300的冲洗效率，保证湿膜300能够顺利疏通。
示例性地，本申请实施例的水阀500可以为电磁阀，这样，可通过信号对电磁阀的开关状态进行控制，从而提高对湿膜300的维护以及加湿的控制效率，进而提高整个间接蒸发冷却装置10的维护效率。
其中，电磁阀的具体结构以及工作原理可直接参照传统技术中的电磁阀，此处不再赘述。
本申请实施例的储水装置400在具体设置时，可以为储水箱，该储水箱通过管道与湿膜300的进水口连通，水阀500可以设置在储水箱与湿膜300连通的管路上，例如，该水阀500可以设置在靠近储水箱的位置，也可以设置在湿膜300的进水口处，本申请实施例不对水阀500的具体位置进行限制。
当需要向湿膜300供水时，可打开水阀500，使储水箱内的水进入湿膜300内，对湿膜300进行加湿，或者冲洗湿膜300内的杂物。
在其他示例中，该储水装置400还可以是输水管道，水阀500可以为设置在输水管道上的 水龙头。当需要向湿膜300供水时，可打开水龙头，使输水管道内的水进入湿膜300内，对湿膜300进行加湿，或者冲洗湿膜300内的杂物。
在一种可选地的实现方式中，本申请实施例的间接蒸发冷却装置10还可以包括颗粒度检测装置600。颗粒度检测装置600设置在室外进风过渡段150的进风端处，颗粒度检测装置600用于检测室外空气102中沙尘含量，以在沙尘含量达到预设值时，通过储水装置400向湿膜300提供水源，以冲洗湿膜300。
例如，该颗粒度检测装置600可以安装在室外进风口151的外部，也可以设置在室外进风口151的内壁上，此处不对该颗粒度检测装置600的具体设置进行限制，只要能够准确检测进入湿膜300内的室外空气102中沙尘含量即可。
本申请实施例通过在室外进风过渡段150的进风端处设置颗粒度检测装置600，以随时检测室外空气102中沙尘含量，从而在该沙尘含量达到预设值时，能够及时对湿膜300进行冲洗，从而避免湿膜300发生堵塞而影响后续过滤，缩短该湿膜300的脏堵周期，保证室外空气102能够及时通过湿膜300以及过滤网200顺利进入换热芯100内，实现对室内空气101的有效散热。
其中，该颗粒度检测装置600的具体结构和工作原理可以直接参照传统技术中的颗粒度检测仪，此处不再赘述。
本申请实施例提供的间接蒸发冷却装置10，通过在室外进风过渡段150设置过滤网200和湿膜300，并将湿膜300设置在过滤网200背离换热芯100的室外空气进风口160的一侧，这样，可先通过湿膜300对室外空气102中尺寸较大的杂物例如柳絮以及大颗粒沙尘进行过滤，再经过滤网200对细小杂物例如小颗粒沙尘进行精细过滤，不仅保证进入换热芯100内的室外空气102的清洁度，而且避免了过滤网200短周期脏堵，延长了过滤网200的使用寿命，降低了对过滤网200的维护成本，同时而且因湿膜300的过滤精度较过滤网200低，从而也延长了湿膜300的维护周期。另外，通过在湿膜300的进水口处连通储水装置400，这样，在湿膜300出现堵塞的情况时，可直接通过储水装置400向湿膜300提供水源，对湿膜300进行冲洗，从而简化了对湿膜300的维护工序，降低了间接蒸发冷却装置10后期的维护难度以及成本。另外，对湿膜300冲洗的过程也是再次加湿湿膜300的过程，从而合理利用了水资源。
实施例二
图2是本申请实施例提供的间接蒸发冷却装置的第二种结构示意图。参照图2所示，与实施例一不同的是，本申请实施例的湿膜300包括第一湿膜310和第二湿膜320，其中，第一湿膜310和第二湿膜320沿室外空气102的流动方向依次设置，且第一湿膜310位于第二湿膜320背离过滤网200的一侧，第一湿膜310与第二湿膜320分体设置。
可以理解的是，因第一湿膜310和第二湿膜320设置在室外进风过渡段150中，因此，该第一湿膜310和第二湿膜320具体沿室外进风过渡段150中空气的流动方向(参照图2中箭头a所指的方向)依次设置，其中，第二湿膜320位于第一湿膜310与过滤网200之间，也即是说，第一湿膜310靠近室外进风口151设置，第二湿膜320靠近过滤网200设置。
可以理解的是，箭头a所指的方向与室外空气102在室外进风过渡段150中的流动方向一致。
本申请实施例中，第一湿膜310与第二湿膜320分体设置具体是指该第一湿膜310和第二湿膜320相互独立，两者中的任意一个可以单独从间接蒸发冷却装置10中拆卸下来。
参照图2所示，本申请实施例的间接蒸发冷却装置10具体工作时，室外空气102从室外进风口151进入室外进风过渡段150后，先经过第一湿膜310，通过该第一湿膜310对室外空气102中尺寸较大的杂物例如柳絮及大颗粒沙尘进行初步过滤，同时对室外空气102进行第一次加湿 降温，接着进入第二湿膜320内，通过该第二湿膜320对室外空气102中剩余的柳絮或者大颗粒沙尘等继续进行过滤，同时对室外空气102进行第二次加湿降温，经过第一湿膜310与第二湿膜320的粗过滤后，室外空气102再经过过滤网200进行精细过滤，即通过该过滤网200对室外空气102中尺寸较小的杂物例如小颗粒沙尘进行过滤，以保证进入换热芯100内的室外空气102的清洁度，经湿膜300以及过滤网200处理后的室外空气102进入室外空气循环通道内，与室内空气循环通道内的室内空气101进行热交换。
本申请实施例通过将湿膜300设置为分体的第一湿膜310和第二湿膜320，这样，当第一湿膜310或者第二湿膜320中的任意一个发生损坏等情况时，可在保证湿膜300性能不衰减的前提下直接对其中的一个损坏的部分进行维护或者更换。
例如，位于室外进风过渡段150最外侧的第一湿膜310因堵塞等发生损坏时，可直接对该第一湿膜310进行简单维护或者更换，而无需对整个湿膜300进行处理，从而降低维护难度以及间接蒸发冷却装置10的物料更换成本。
参照图2所示，在一些示例中，第一湿膜310与第二湿膜320相对的侧壁相接触，也即是说，第一湿膜310与第二湿膜320相对的侧壁之间的间隙为零，这样，可在储水装置400上连通一个管道，且该管道的出水口与第一湿膜310的进水口连通，或者与第二湿膜320的进水口连通，均可实现对第一湿膜310和第二湿膜320的统一清洗维护以及加湿，从而简化了间接蒸发冷却装置10的装配工序，提高了湿膜300的维护效率。
另外，本申请实施例通过将第一湿膜310与第二湿膜320相对的侧壁接触设置，还节约湿膜300在间接蒸发冷却装置10内的占用空间，从而方便间接蒸发冷却装置10中其他零部件的安装。
在其他示例中，第一湿膜310与第二湿膜320还可沿室外进风过渡段150的延伸方向间隔设置(图中未示出)，换句话说，第一湿膜310与第二湿膜320相对的侧壁之间具有间隙，储水装置400可分别与第一湿膜310和第二湿膜320的进水口连通，这样，当任意一个湿膜300需要清理或者加湿时，可导通储水装置400与对应的湿膜300之间的管路，使得储水装置400内的水输送至相应的湿膜300内，对该湿膜300进行清洗或者加湿。
例如，当第一湿膜310需要清理或者加湿时，可导通储水装置400与第一湿膜310之间的管路，使得储水装置400内水输送至第一湿膜310内，从而对该第一湿膜310进行清理或者加湿。
当然，可将储水装置400内的水同时输送至第一湿膜310和第二湿膜320内，以对两个湿膜300同时进行维护清理或者加湿。
其中，可以在储水装置400与第一湿膜310和第二湿膜320的连通管路上设置一个三通阀，该三通阀的第一端口与储水装置400连通，三通阀的第二端口与第一湿膜310的进水口连通，三通阀的第三端口与第二湿膜320的进水口连通，这样，通过对三通阀进行操作，以及时实现储水装置400与第一湿膜310之间的导通或者储水装置400与第二湿膜320之间的导通。
因第一湿膜310对室外空气102中的柳絮起主要过滤作用，因此该第一湿膜310相比于第二湿膜320更易堵塞，因此，在具体设置时，本申请实施例的第一湿膜310的厚度可小于第二湿膜320的厚度。
需要说明的是，第一湿膜310或者第二湿膜320的厚度是指第一湿膜310或者第二湿膜320沿室外空气102的流动方向相对设置的两个侧壁之间的距离。其中，该室外空气102的流动方向具体是指室外进风过渡段150中空气的流动方向，参照图2中a箭头所示。
本申请实施例通过将第一湿膜310的厚度设置为小于第二湿膜320的厚度，使得第一湿膜310更加便于维护或者更换，从而进一步降低了维护难度以及物料更换成本。
具体实现时，第一湿膜310的厚度可以设置为10mm-20mm。
本申请实施例通过将第一湿膜310的厚度设置在上述范围内，以在保证第一湿膜310对室外空气102的柳絮以及大颗粒沙尘的过滤效果的同时，方便了第一湿膜310的单独维护以及更换。例如，第一湿膜310的厚度可以设置为10mm、12mm、14mm、16mm、18mm或者29mm等合适的数值。
另外，第二湿膜320的厚度在具体设置时，可以是第一湿膜310厚度的10倍-15倍，这样可确保整个湿膜300对室外空气102中的柳絮以及大颗粒沙尘的过滤效果。例如，当第一湿膜310的厚度为10mm时，第二湿膜320的厚度可以为100mm-150mm之间，例如，当第一湿膜310的厚度为10mm时，第二湿膜320的厚度可以设置为100mm、110mm、130mm或者150mm等合适的数值，从而保证室外空气102经第一湿膜310和第二湿膜320后能够完成对大尺寸杂物例如柳絮或者大颗粒沙尘的有效过滤。同时，也保证室外空气102在经过第一湿膜310和第二湿膜320后能够得到有效的降温，从而确保本申请实施例的间接蒸发冷却装置10的换热效率。
实施例三
图3是本申请实施例提供的间接蒸发冷却装置的第三种结构示意图。参照图3所示，在实施例一或者实施例二的基础上，本申请实施例的间接蒸发冷却装置10还可以包括水箱700，该水箱700与湿膜300的出水口连通，且水箱700上形成有排水口710，排水口710用于排出水箱700内的污水。
例如，可以在本申请实施例的间接蒸发冷却装置10内设置一水箱700，将湿膜300的出水口与该水箱700连通，同时在水箱700上设置排水口710，这样，储水装置400内的水输送至湿膜300内，对湿膜300进行多次清洗以及加湿后可集中排入水箱700内，而当水箱700内的污水积攒过多后，可集中排出至下水道等位置，从而降低清洗后的污水对环境造成污染。
其中，排水口710可以设置在水箱700的底部，以保证水箱700内的污水彻底排出。
图4是本申请实施例提供的间接蒸发冷却装置的第四种结构示意图。参照图4所示，本申请实施例的间接蒸发冷却装置10还可以包括水泵800。水箱700上具有补水口720，储水装置400与补水口720连通，水箱700上还具有出水口，出水口与湿膜300的进水口连通，换句话说，储水装置400通过水箱700与湿膜300连通，水泵800设置在水箱700与湿膜300的进水口连通的管路上。例如，该水泵800设置在水箱700的出水口处。
其中，补水口720可以设置在水箱700的侧壁上。
本申请实施例通过将水箱700连通至湿膜300的进水口，这样，当需要对湿膜300进行清洗时，可通过水泵800将水箱700内的水打入湿膜300内，对湿膜300上的柳絮以及大颗粒沙尘进行冲洗，冲洗后的水直接排入水箱700内，可供再次冲洗使用，不仅保证了对湿膜300的清理及时性和方便性，而且水箱700内的水可循环使用，也进一步降低了对水资源的浪费。
另外，通过将储水装置400与水箱700连通，这样当水箱700内的水无法继续冲洗湿膜300时，可随时排出，并通过该储水装置400随时为水箱700内补充清洁水，保证水箱700内的循环水的清洁度，使其始终满足湿膜300的加湿与清洗要求。
本申请实施例的水泵800可以包括但不限于计量泵、离心泵、轴流泵及混流泵中的任意一种。为了观测水箱700进入湿膜300中的水的流量，可以在水泵800上设置流量测量仪。
继续参照图4所示，本申请实施例的间接蒸发冷却装置10还可以包括液位传感器730，液位传感器730设置在水箱700内，液位传感器730用于检测水箱700内的水位，确保水箱700内的循环水充足。
其中，液位传感器730可以包括但不限于浮筒式液位传感器、浮球式液位传感器、静压式液位传感器中的任意一种，具体的结构和工作原理可直接参照传统的液位传感器，此处不再赘述。
在本申请实施例的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应作广义理解，例如，可以是固定连接，也可以是通过中间媒介间接相连，可以是两个元件内部的连通或者两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请实施例中的具体含义。
本申请实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
