相关申请的交叉引用
本申请要求在2021年10月29日提交中国专利局、申请号为202111281082.8、名称为“散热膜和电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请属于通信技术领域，具体涉及一种散热膜以及电子设备。
背景技术
随着手机、平板电脑等电子设备的功能日益丰富，电子设备的发热问题也越来越凸出，散热膜在电子设备中的应用也越来越广泛。例如，为了对电子设备的扬声器进行散热，通常会在扬声器上设置散热膜。
在电子设备中，扬声器通常会邻近电池设置。为了实现较好的散热效果，散热膜不仅需要粘贴在扬声器上，还需要部分延伸至电池的上方，以扩大散热面积。在具体的应用中，为了避免散热膜延伸至电池上方的部分对天线性能造成影响，散热膜延伸至电池上方的部分通常需要需要固定在电池上。
然而，由于散热膜固定粘接在电池上，拉扯散热膜会对电池造成损坏风险。尤其在电子设备发生撞击或者跌落，电池在电池仓内晃动的情况下，由于散热膜对电池形成拉扯，很容易将电池拉扯变形，甚至，还有可能导致电池漏液起火，存在较大的安全风险。

具体的，本申请实施例提供了一种散热膜，所述散热膜可以用于图1所示的电子设备，所述电子设备可以包括邻近设置的电池21和扬声器22，电池21具体可以包括电池本体211以及设置于电池本体211边缘的电池保护膜212。所述散热膜具体可以包括：依次叠层设置的第一保护层11、第一粘接层12、石墨散热层13以及第二保护层14。如图3所示，所述散热膜可以包括第一连接区域A和第二连接区域B，第一连接区域A与扬声器22的位置对应，第二连接区域B与电池21的部分位置对应；第一保护层11设置于第二连接区域B，以对第一粘接层12位于第二连接区域B的区域进行遮挡；第一保护层11在远离第一粘接层12的一侧设置有第二粘接层15，第二粘接层15的位置与电池保护膜212对应。
本申请实施例中，所述散热膜上设置第一连接区域A和第二连接区域B，第一连接区域A与扬声器22的位置对应，第二连接区域B与电池21的部分位置对应。第一保护层11连接在第二连接区域B，以对第一粘接层12位于第二连接区域B的区域进行遮挡，以避免第一粘接层12与第二连接区域B对应的电池21直接粘接。第一保护层11在远离第一粘接层12的一侧设置有第二粘接层15，第二粘接层15的位置与电池保护膜212对应，第二粘接层15可以用于与电池保护膜212连接，以固定所述散热膜延伸至电池21上方的部分，使所述散热膜与电池21之间保持稳定的间隙，避免所述散热膜对天线性能造成影响。由于所述散热膜可以通过第二粘接层15连接至电池保护膜212上，避免了直接将所述散热膜固定在电池本体211上对电池本体211形成的拉扯，即使在电池本体211晃动的情况下，仍然可以避免所述散热膜对电池本体211形成的拉扯变形和安全隐患，极大的提高了所述散热膜的使用安全。
具体的，所述电子设备还可以包括框体20，框体20上设置有用于容纳所述电池21的电池仓。电池21可以包括电池本体211和电池保护膜212，电池本体211可以嵌设于所述电池仓内，电池保护膜212可 以嵌设于电池本体211底部和所述电池仓之间，并至少部分延伸至所述电池仓的外部。电池保护膜212可以固定在所述电池仓内，以避免电池本体211在所述电池仓内晃动，保护电池本体211，并且，在需要将电池本体211从所述电池仓内取出时，通过拉拽电池保护膜212即可将电池本体211取出。
示例地，电池保护膜212可以为聚酯(Polyester Film，PET)薄膜。PET薄膜的机械性能优良，具有较好的强韧性、抗张强度和抗冲击强度，因此，在电池保护膜212为PET薄膜的情况下，可以进一步提升电池保护膜212对于电池本体211的保护效果。
当然，在实际应用中，电池保护膜212也可以采用其他的热塑性塑料制成，本申请实施例对于电池保护膜212的具体材质可以不做限定。
具体的，扬声器22可以邻近电池21设置，由于扬声器22在使用过程中产生的热量较多，因此，需要将本申请实施例所述的散热膜设置在扬声器22上，实现散热的效果。在实际应用中，为了提高散热效果，通常需要所述散热膜具有较大的散热面积，因此，所述散热膜需要部分延伸至电池21的上方。
本申请实施例中，可以将所述散热膜分为两个区域，其中，位于扬声器22上方且与扬声器22连接的区域为第一连接区域A，延伸至电池21的上方且与电池21的部分位置相对的区域为第二连接区域B。
具体的，所述散热膜可以包括依次叠层设置的第一保护层11、第一粘接层12、石墨散热层13以及第二保护层14。其中，第一保护层11设置于第二连接区域B，以对第一粘接层12位于第二连接区域B的区域进行遮挡，避免第一粘接层12直接粘接到电池本体211上。并且，第一保护层11在远离所述第一粘接层12的一侧设置有第二粘接层15，第二粘接层15的位置与电池保护膜212对应。第二粘接层15可以用于与电池保护膜212连接，以固定所述散热膜延伸至电池21上方的部分，使所述散热膜与电池21之间保持稳定的间隙，避免所述散热膜对天线性能造成影响。由于所述散热膜可以通过第二粘接层15连接至电池保护膜212上，避免了直接将所述散热膜固定在电池本体211上对电池本体211形成的拉扯，即使在电池本体211晃动的情况下，仍然可以避免所述散热膜对电池本体211形成的拉扯变形和安全隐患，极 大的提高了所述散热膜的使用安全。
在实际应用中，石墨散热层13可以用于散热，第一保护层11和第二保护层14可以分别位于石墨散热层13的两侧，用于保护石墨散热层13。第一保护层11和第二保护层14可以为PET薄膜。PET薄膜的机械性能优良，具有较好的强韧性、抗张强度和抗冲击强度，因此，在第一保护层11和第二保护层14为PET薄膜的情况下，可以进一步提升其对于所述石墨散热膜的保护效果。
可选地，第二粘接层15与电池保护膜212之间的粘性低于第一粘接层12与扬声器22之间的粘性，也即，第一粘接层12的粘性较强，而第二粘接层15的粘性较弱。这样，在拆卸扬声器22的时候，由于第一粘接层12与扬声器22之间的粘性较强，所述散热膜可以跟随扬声器22一起被拆下。而由于第二粘接层15与电池保护膜212之间的粘性较弱，第二粘接层15与电池保护膜212之间的粘接很容易被解除，因此，在拆卸扬声器22的情况下，所述散热膜上的第二粘接层15很容易从电池保护膜212上脱离，提高了扬声器22的拆卸便利性。
可选地，所述电子设备上还设置有天线23；石墨散热层13在与天线23相对的位置设置有避让部131，避让部131可以用于形成天线23的净空区，以增大天线23的净空区域，提升天线23的性能。
具体的，可以对石墨散热层13上与天线23相对的位置进行挖空处理，以形成避让部131。
可选地，在避让部131对应的位置，第二保护层14与第一粘接层12可以直接连接，以降低所述散热膜在避让部131的厚度，以避免所述散热膜的叠层过厚顶起所述电子设备中的电池盖，有利于所述电子设备内部的器件布局。
在本申请的一种可选实施例中，石墨散热层13具体可以包括：依次叠层设置的第一石墨层132、第三粘接层133以及第二石墨层134；其中，第一石墨层132与第一粘接层12连接，第二石墨层134与第二保护层14连接；避让部131依次贯穿于第一石墨层132、第三粘接层133以及第二石墨层134。
在实际应用中，通过叠层设置的第一石墨层132和第二石墨层134，可以提升石墨散热层13的散热效果。第三粘接层133则可以用于粘接第一石墨层132和第二石墨层134，以将第一石墨层132和第二石墨层 134连接在一起。避让部131可以依次贯穿第一石墨层132、第三粘接层133以及第二石墨层134，以形成贯穿整个石墨散热层13的结构。
所述散热膜还包括：离型膜16，离型膜16连接于第二保护层14远离石墨散热层13的一侧；其中，离型膜16的形状与扬声器22的形状适配。
具体的，由于离型膜16的形状与扬声器22的形状适配，在需要将所述散热膜粘接在扬声器22的情况下，可以将离型膜13与扬声器22的外形对齐，即可实现所述散热膜在扬声器22上的定位。这样，就可以避免在框体20上镭雕定位线或者设置定位柱以实现所述散热膜定位的操作，简化框体20的加工工艺。
可选地，离型膜16粘接于第二保护层14，且离型膜16与第二保护层14之间粘性小于第一粘接层12与扬声器22之间的粘性。这样，在将所散热膜的第一粘接层12粘接在扬声器22上之后，由于离型膜16与第二保护层14之间粘性小于第一粘接层12与扬声器22之间的粘性，可以将离型膜16从第二保护层14上撕下，以降低所述散热膜的高度，避免所述散热膜将所述电子设备的电池盖顶起，便于所述电子设备内部的器件布局。
可选地，所述散热膜还可以包括：底膜，所述底膜设置于第一保护层11远离石墨散热层13的一侧，所述底膜粘接于第一粘接层12和第二粘接层15。在实际应用中，在需要将所述散热膜粘接在扬声器22的情况下，可以将所述底膜从第一粘接层12和第二粘接层15上撕下，并将第一粘接层12粘接在扬声器22，并将第二粘接层15粘接在电池保护膜212上即可。
综上，本申请实施例所述的散热膜至少可以包括以下优点：
本申请实施例中，所述散热膜上设置第一连接区域和第二连接区域，所述第一连接区域与所述扬声器的位置对应，所述第二连接区域与所述电池的部分位置对应。第一保护层连接在所述第二连接区域，以对所述第一粘接层位于所述第二连接区域的区域进行遮挡，以避免第一粘接层与所述第二连接区域对应的电池本体直接粘接。所述第一保护层在远离所述第一粘接层的一侧设置有第二粘接层，所述第二粘接层的位置与所述电池保护膜对应，所述第二粘接层可以用于与所述电池保护膜连接，以固定散热膜延伸至所述电池上方的部分，使所述 散热膜与所述电池之间保持稳定的间隙，避免所述散热膜对天线性能造成影响。由于所述散热膜可以通过所述第二粘接层连接至电池保护膜上，避免了直接将所述散热膜固定在所述电池本体上对电池本体形成的拉扯，即使在电池本体晃动的情况下，仍然可以避免所述散热膜对电池本体形成的拉扯变形和安全隐患，极大的提高了所述散热膜的使用安全。
本申请实施例还提供了一种电子设备，所述电子设备具体可以包括：框体20、电池21、扬声器22以及上述任一实施例所述的散热膜；其中，电池21、扬声器22皆设置于框体20内，且电池21和扬声器22邻近设置；电池21可以包括电池本体211以及设置于电池本体211边缘的电池保护膜212；散热膜位于第一连接区域A的第一粘接层12与扬声器22粘接，所述散热膜位于第二连接区域B的第二粘接层15与电池保护膜212粘接。
本申请实施例中，所述散热膜上设置第一连接区域A和第二连接区域B，第一连接区域A与扬声器22的位置对应，第二连接区域B与电池21的部分位置对应。第一保护层11连接在第二连接区域B，以对第一粘接层12位于第二连接区域B的区域进行遮挡，以避免第一粘接层12与第二连接区域B对应的电池奔头211直接粘接。第一保护层11在远离第一粘接层12的一侧设置有第二粘接层15，第二粘接层15的位置与电池保护膜212对应，第二粘接层15可以用于与电池保护膜212连接，以固定散热膜延伸至电池21上方的部分，使所述散热膜与电池21之间保持稳定的间隙，避免所述散热膜对天线23性能造成影响。由于所述散热膜可以通过第二粘接层15连接至电池保护膜212上，避免了直接将所述散热膜固定在电池本体211上对电池本体211形成的拉扯，即使在电池本体211晃动的情况下，仍然可以避免所述散热膜对电池本体211形成的拉扯变形和安全隐患，极大的提高了所述散热膜的使用安全。
