本申请主张在2014年12月25日在中国提交的中国专利申请号No.201410827544.5的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及移动通信领域，尤其涉及一种利于散热的移动终端。
背景技术
随着移动通信技术的快速发展，移动终端硬件的不断升级和新功能的日益增多，移动终端产品主板上的器件集成度和密度越来越高，而受限于移动终端的整机尺寸大小以及电池的厚度，其主板的空间被逐渐压缩。实现通信，显示，声音，充电等不同功能的IC(Integrated Circuit，集成电路)都密集的分布在主板上，导致热源过于集中，移动终端的散热环境较差。用户在使用过程中，尤其是在充电的同时使用移动终端会出现移动终端局部发热、发烫的情况。
为解决移动终端充电过程中局部发烫问题，现在常见的解决方法是检测移动终端运行时CPU(Central Processing Unit，中央处理器)的温度，并设定相应的温度门限值来动态的调节CPU的工作频率，当CPU温度达到温度门限时对CPU进行降频操作，以适当减小移动终端主板的发热；或者通过在充电过程中减小充电电流，直接降低充电IC的热功耗，从而缓解整机的外壳温升。
以上两种方式都是通过调节主要热源的功耗，减小了移动终端的发热量，然而，降低CPU工作频率会牺牲了移动终端的性能、减小充电电流也影响了移动终端的充电效率，不利于用户体验。
发明内容
为克服现有技术中移动终端局部发热、发烫的问题，本公开实施例提供了一种移动终端，包括第一电路板、第二电路板和电池，所述第一电路板位于所述电池的底部，所述第二电路板位于所述电池的顶部，所述第一电路板上设有第一充电IC，所述第二电路板上设有CPU，所述第一充电IC用于为所述电池 充电。
本公开实施例将第一充电IC设置在第一电路板上，将CPU设置在第二电路板上，第一电路板设于电池的底部，第二电路板设于电池的顶部，实现了CPU、充电IC等热源部件的分散设置，使移动终端内部的散热空间被有效利用，移动终端的发热更加均匀。克服了现有技术中移动终端局部发热、发烫的问题，利于移动终端的散热，提升了用户使用体验。

当本公开实施例提及“第一”、“第二”等序数词时，除非根据上下文其确实表达顺序之意，应当理解为仅仅是起区分之用。
第一实施例：
请参考图1，是本公开移动终端的第一实施例的结构示意图，移动终端包括：第一电路板1、第二电路板2和电池3，第二电路板2上设有CPU，第一电路板1上设有第一充电IC4，第一充电IC4用于为电池3充电。
在本实施例中，电池3位于移动终端中部开设的电池仓内，第一电路板1位于电池3的底部，第二电路板2位于电池3的顶部。通过将第一电路板1和第二电路板2相互远离布置，可防止在移动终端充电时，第一电路板1上的第一充电IC4和第二电路板2上的CPU的热量叠加，造成移动终端局部温度过高，影响用户使用体验。
在本实施例中，第二电路板2为移动终端主板，第一电路板1为移动终端副板(也作小板)，第二电路板2上还可以设有电源管理IC、存储器IC、射频放大器；第一电路板1还可以设有音腔和马达。
移动终端还包括第一散热件和第二散热件，第一散热件与第一电路板1接触，第二散热件与第二电路板2接触，第一散热件和第二散热件均延伸至电池的背部靠近移动终端后盖的位置。
在本实施例中，第一散热件可以是第一石墨片，第二散热件可以是第二石墨片。
在本实施例中，移动终端可以是手机、平板电脑、MP3、MP4或笔记本电脑等。
本实施例中的移动终端还包括USB(Universal Serial Bus，通用串行总线)接口5，该USB接口5位于移动终端底部，可以设置在第一电路板1上。将USB接口5设于靠近充电IC的第一电路板1上，可以减小移动终端供电路径上的压降损耗，提升移动终端充电效率。
本实施例通过将CPU、电源管理IC、存储器IC、射频等热源设在位于电池顶部的主板上，将充电IC、音腔、马达设在位于电池底部的副板上，减小了移动终端充电过程中充电IC的发热对移动终端主板的影响，通过分散设置的方式，使移动终端内部的散热空间被有效利用，移动终端的发热更加均匀。
第二实施例：
请参考图2，是本公开移动终端的第二实施例的结构示意图，移动终端包括：第一电路板1’、第二电路板2’和电池3’，第二电路板2’上设有CPU，第一电路板1’上设有第一充电IC4’，第一充电IC4’用于为电池充电。
在本实施例中，第二电路板2’为移动终端主板，第一电路板1’为移动终端副板，第二电路板2’上还可以设有电源管理IC、存储器IC、射频放大器；第一电路板还可以设有音腔和马达。
与实施例一不同的是，第二电路板2’上设有第二充电IC5’，第二充电IC5’用于为第二电路板2’供电。在本实施例中，第二充电IC5’还用于为电池充电。
在本实施例中，当移动终端处于待机状态下充电时，由于第一充电IC4’和第二充电IC5’同时为电池3’充电，且该两个充电IC相距较远，可以充分利用移动终端内部的散热空间，平衡移动终端内部热量，避免局部过热。
而当移动终端在较大负载(如玩游戏，看高清视频)情况下充电时，由于主板(在本实施例中为第二电路板)端除第二充电IC5’外，CPU、电源管理IC、存储器IC、射频放大器均处于发热状态，用户或移动终端自身均可以通过分别配置第一充电IC4’、第二充电IC5’的充电电流进行温度的控制，如将第一充电IC4’的充电电流配置得相对较高一些，将第二充电IC5’的充电电流配置相对低些。从而控制主板端的发热量，使移动终端的整体发热更加均匀。
本实施例通过在主板上设置第二充电IC，一方面使第二充电IC辅助第一充电IC，提升了移动终端在待机充电状态下的充电效率，移动终端可以在整体发热量更均匀的状况下使用更大功率对电池充电；另一方面使移动终端在较大负载情况下充电时，通过第二充电IC为主板供电，避免了实施例一中通过第一充电IC为主板供电，供电回路过长引发电能损耗较大的情况，提升了供电效率，也有效控制了主板端的发热量。
发明以上所述仅为本公开的较佳实施例而已，并不用以限制本公开，如，本公开不仅限于包括第一电路板、第二电路板、第一充电IC、第二充电IC，还可以包括第三电路板、第三充电IC等。凡在本公开的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本公开的保护范围之内。
