附图说明
图1为本发明机柜较佳实施例的结构示意图。
本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
为了使本发明实施例的技术方案更加清楚、明了，下面将结合附图作 进一步详述。
应当理解，此处所描述的具体实施例仅仅用以解释本发明实施例，并不用于限定本发明实施例。
本发明实施例的主要解决方案是：简化挡水板的结构和数量，最主要的是在进风道和/或出风道的侧壁增加用于吸收水头能量的挡水吸能板，能够有效吸收水头的能量，从而防止水反弹到机柜里面，而且整个防水方案对风道的阻力小，从而使得整个机柜系统的防水和散热能达到最佳的平衡，避免现有技术中室外直通风机柜防水结构复杂，造成对机柜系统散热能力不利影响的问题。
由于现有技术中室外直通风机柜的IPX5防水结构较复杂，而且对风道的阻力大，在挡水的同时对机柜的散热造成了不利的影响。
本发明实施例提供一种解决方案，可以避免室外直通风机柜防水结构复杂，造成对机柜系统散热能力不利影响的问题。
本实施例考虑到：从现有的多次淋水测试的结果来分析，机柜进水主要是水流不规则的反弹后进入到了机柜里面，那么机柜防水除防止水流直冲入机柜里面外，还需要把反弹水也有效防住，另外所有的防水结构对风道的影响要尽可能地小，本发明实施例就是基于这些考量来设计的。
具体地，如图1所示，本发明较佳实施例提出一种机柜防水结构，所述机柜包括柜体，所述柜体上设有进风道和出风道，所述进风道和/或出风道的侧壁上设有至少一用以吸收水头能量的挡水吸能板103。
也就是说，根据需要可以在进风道的侧壁上设置挡水吸能板103，也可以在出风道的侧壁上设置挡水吸能板103，也可以在进风道和出风道的侧壁上均设置挡水吸能板103，由此，通过在进风道和/或出风道的侧壁增加用于吸收水头能量的挡水吸能板103，能够有效吸收水头的能量，从而防止水反弹到机柜里面，而且整个防水方案对风道的阻力小，从而使得整个机柜 系统的防水和散热能达到最佳的平衡，避免现有技术中室外直通风机柜防水结构复杂，造成对机柜系统散热能力不利影响的问题。
更为具体地，在本实施例中，所述柜体包括柜门101和罩设在所述柜门101上的风罩102，所述进风道和出风道设置在所述风罩102的空腔内，所述柜门101上设有连通所述进风道的进风口，以及连通所述出风道的出风口，机柜的进风路径和出风路径如图1中箭头所示。
所述挡水吸能板103设置在所述风罩102的内壁上于所述进风道和/或出风道的位置。
作为一种较优的实施方式，所述进风道内的挡水吸能板103设置在所述风罩102相对所述柜门101的侧壁上，且正对所述进风口。
所述出风道内的挡水吸能板103设置在所述风罩102相对所述柜门101的侧壁上，且正对所述出风口。
在本发明一实施方式中，为了更好的提高机柜的防水效果，还可以在风罩102内于所述进风口附近和/或出风口附近设置挡水板104。
其中，挡水板104的数量及位置可以根据需要灵活设置，比如，可以设置一块或两块。
如图1所示，作为一种实施方式，可以在风罩102内于进风口附近设置一块挡水板104；在出风口附近设置两块挡水板104，其中一块位于所述风罩102相对所述柜门101的侧壁上，另一块位于所述出风口处。
其中，出风口附近的两块挡水板104可以呈平行状设置，且相对风罩102侧壁呈倾斜设置。进风口处的挡水板104可以设置在进风口处，并可以相对风罩102侧壁呈倾斜设置。
在本发明一实施方式中，为了避免灰尘进入机柜内，还可以在风罩102的侧壁上设置防尘网105。
相比现有技术，本发明实施例在进风口设置了一块普通挡水板104，在 进风道的侧壁上设置了一块挡水吸能板103，在出风口设置了两块普通挡水板104，在出风道的侧壁上设置了一块挡水吸能板103，结构简单，防水效果好，对风道的阻力小，从而使得整个机柜系统的防水和散热能达到最佳的平衡。最终能使机柜系统结构紧凑，安装简单，成本低，机柜散热能力也能大大提高。
此外，本发明实施例还提出一种通风机柜，包括：柜体，所述柜体上设有进风道和出风道，该机柜可以采用上述实施例所述的机柜防水结构。
此外，如图1所示，在风罩102内于所述进风道与所述出风道之间还设有中间隔板106，以隔开两风道。
在安装机柜时，首先，将挡水吸能板103、普通挡水板104、中间隔板106安装到风罩102上；然后，将风罩102安装到柜门101上；最后，将防尘网105安装到风罩102上。
相比现有技术中在室外直通风机柜做IPX5的防水结构时，往往采用较复杂的迷宫，在挡住水的同时把风也挡住了，造成了对机柜系统散热能力不利影响的问题。
本发明实施例简化了挡水板104的结构和数量，最主要的是在进、出风道的侧壁各增加了一块吸收水头能量的挡水吸能板103，有效吸收水头的能量，从而防止水反弹到机柜里面，而且整个防水方案对风道的阻力小，从而使得整个机柜系统的防水和散热能达到最佳的平衡。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本发明的专利保护范围内。
工业实用性
本发明实施例的技术方案，简化了挡水板的结构和数量，最主要的是在进风道和/或出风道的侧壁增加用于吸收水头能量的挡水吸能板，能够有 效吸收水头的能量，从而防止水反弹到机柜里面，而且整个防水方案对风道的阻力小，从而使得整个机柜系统的防水和散热能达到最佳的平衡，避免了现有技术中室外直通风机柜防水结构复杂，造成对机柜系统散热能力不利影响的问题。
