本发明提出一种保温型材，应用于热水器。
参照图1和2，该保温型材100包括多个微气泡20、及包裹所述多个微气泡20的至少一层防护层10；
所述防护层10设置有进气孔11和排气孔12；
所述保温型材100内还形成有连接所述进气孔11和排气孔12的充气通道30，所述多个微气泡20围绕所述充气通道30分布；
每一所述微气泡20均形成有开口21，相邻所述微气泡20通过所述开口21连通，每一所述微气泡20内还填充有隔热气体。
在本实施例中，该保温型材100包括一层防护层10，在其他实施例中，该防护层10还可以由多层防护层10进行叠加，该防护层10包裹多个微气泡20，每一微气泡20内均填充有隔热气体，每一微气泡20还形成有开口21，任一组相邻的两个微气泡20之间均通过所述开口21连通，以便在隔热气体充入时，无需对单个微气泡20单独进行隔热气体的填充，为了便于保温型材的气压调节、排除混入的空气、以及充入隔热气体等，在所述防护层10上还设置了便于充气的进气孔11和便于抽空气的排气孔12，所述保温型材100内还形成有连接所述进气孔11和排气孔12的充气通道30，所述多个微气泡20围绕所述充气通道30分布，在其他实施例中，该充气通道30还可以设置成多个，以便于向所述微气泡20内充气。

进一步地，所述隔热气体的导热系数低于25mW/（m•K），优选地，隔热气体为氩气、氪气、氙气、二氧化碳、环戊烷、及异戊烷中的至少一种。

在本实施例中，所述防护层10还设置有进气孔11和排气孔12，由于隔热气体的密度大于空气的密度，所以为了便于对所述保温型材100进行充气，将所述进气孔11和排气孔12分布于所述防护层10的上下或左右两端，且进气孔11的位置低于排气孔12的位置，在对所述保温型材100进行充气时，将所述保温型材100水平放置，然后通过所述进气孔11充入隔热气体，隔热气体会挤压微气泡20及微气泡20之间的间隙内的空气，使其通过所述排气孔12排出，所述密封所述进气孔11和排气孔12的密封件可以是电控电磁阀，还可以是手动控制的低压阀门。
进一步地，所述防护层10及所述微气泡20的材质为塑料膜、金属箔复合塑料膜、镀有金属层的塑料复合膜中的一层或两层以上的复合膜材料。
在本实施例中，所述防护层10和微气泡20均采用导热系数比较低的、不透气的软质膜，如塑料膜、金属箔复合塑料膜、镀有金属层的塑料复合膜中的一层或两层以上的复合膜材料，如此，一方面可以进一步增强保温型材的隔热效果，另一方面可以使该保温型材的弯折性更好，更方便应用于热水器的安装。
进一步地，参照图1和2，该保温型材100还包括设于所述防护层10内表面和/或外表面的反射层40。
在本实施例中，在所述防护层10的内表面和/或外表面还设置有反射传热、且不会增加额外的边缘热桥效应的反射层40，所述反射层40为膜层或涂层，如此，通过反射层40对辐射热的反射，可以进一步提高保温型材100的保温性能，反射层40可以为金属箔复合塑料膜、镀有金属层的塑料复合膜、金属反射涂层、纳米反射涂层中的一层或多层结构。
本发明的保温型材100，在进行充气时，可以采用以下充气方式：
（一）、用抽气装置如真空泵，经所述排气孔12和充气通道30抽取所述微气泡20及微气泡20之间的间隙内的空气，然后在第一预设时间之后，即预测的空气完全抽出时间之后，密封排气孔12，打开进气孔11向所述微气泡20及微气泡20之间的间隙内充隔热气体，最后，在第二预设时间之后，即根据微气泡20的总体积和间隙的总体积预先设定的隔热气体能够完全填充的时间之后，停止充气，密封所述进气孔11，完成保温型材100的充气；
（二）、依据微气泡20及防护层10的材料构成设定其满压值，然后在预设时间内经所述进气孔11和充气通道30持续向所述微气泡20及微气泡20之间的间隙内填充隔热气体，最后在检测到微气泡20及防护层10满压时，停止充气，密封所述进气孔11和排气孔12，完成保温型材100的充气；
（三）、依据微气泡20及防护层10的材料构成设定其满压值，然后经所述排气孔12抽取所述微气泡20及微气泡20之间的间隙内的空气，同时，通过所述进气孔11和充气通道30向所述微气泡20及微气泡20之间的间隙内充隔热气体，最后在检测到所述微气泡20及防护层10满压时，停止抽气和充气，密封所述排气孔12和进气孔11，完成保温型材100的充气；
（四）、将所述保温型材100放置于一充满隔热气体的环境中，然后通过所述排气孔12和充气通道30抽取所述微气泡20及微气泡20之间的间隙内的空气，在抽取预设时间之后，打开所述进气孔11利用保温型材100的内外压差使隔热气体充入所述微气泡20及微气泡20之间的间隙内，最后检测到保温型材100的内外压力平衡时，密封所述排气孔12和进气孔11。
本发明的另一目的在于提供一种热水器，该热水器的内胆外壁包覆有如上所述的保温型材100。
在本实施例中，该热水器的内胆外壁包覆有如上所述的保温型材100，该保温型材100包括多个微气泡20、及包裹所述多个微气泡20的至少一层防护层10，所述防护层10设置有进气孔11和排气孔12，所述保温型材100内还形成有连接所述进气孔11和排气孔12的充气通道30，所述多个微气泡20围绕所述充气通道30分布，每一所述微气泡20均形成有开口21，相邻所述微气泡20通过所述开口21连通，每一所述微气泡20内还填充有隔热气体。设置于该热水器的内胆和外壳之间的保温型材100，通过设置连接进气孔11和排气孔12的充气通道30，填充导热系数较低的隔热气体，降低了保温型材100的导热性，提高了保温型材100的保温性能，进而提高了热水器的保温性能，而且填充隔热气体使保温型材100在包裹热水器的内胆而发生长期的弯折时，保温型材100的隔热气体会重新排列分布，不会发生机械破坏，进一步地提高了保温型材的使用寿命和保温效果。
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，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
