 本发明的最佳实施方式
为了使本申请实施例中的技术方案及优点更加清楚明白，以下结合附图对本申请的示例性实施例进行进一步详细的说明，显然，所描述的实施例仅是本申请的一部分实施例，而不是所有实施例的穷举。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
本实施例提供一种切片机，用于将硬脆材料棒切割成片状结构。硬脆材料棒可以为硅棒、蓝宝石棒等。本实施例仅以硅棒为例对切片机进行说明。
图1为本申请实施例提供的切片机中冷却***的原理图。如图1所示，本实施例提供的切片机包括：框架及设置于框架上的切割装置和切割线冷却***。
切割装置上的切割线用于将硅棒切成薄片状结构。由于切割线在于硅棒摩擦切割的过程中会产生热量，过高温度将会影响切割线的切割质量，因此通过冷却***对切割线进行冷却，以使切割线的温度保持在正常的工作温度范围，保障切割质量。切割线为金刚线，其上附着有多个金刚石。
冷却***包括：供液容器3、过滤容器4、换热器5和喷淋器6。其中，供液容器3用于容纳切割液，切割液是一种用于对切割线进行冷却的液体，对切割线及硅棒不产生化学反应，进而不会损伤切割线或硅棒。各容器之间通过管路相连，管路上设置有供液泵，用于提供动力以使供液容器3中的切割液依次经过滤容器4、换热器5和喷淋器6后喷洒至切割装置对切割线进行冷却。
具体的，供液容器3与过滤容器4之间的管路上设置有供液泵31。过滤容器4用于对切割液进行过滤，滤除其中的杂质、固体颗粒等。切割液经过换热器5进行降温，降温后的切割液通过喷淋器6喷洒至切割装置。
本实施例提供的技术方案，通过在切片机的框架上设置切割线冷却***，冷却***包括：通过管路依次连接的供液容器、过滤容器、换热器和喷淋器，管路上设置有供液泵，用于提供动力，使供液容器中的切割液依次经过过滤容器、换热器和喷淋器喷射至切割装置，以对切割线进行冷却，保障切割质量。
上述换热器对切割液进行冷却的方式可以为风冷，也可以为水冷，或者为其他冷却方式。本实施例采用冷却液实现水冷的方式，例如：在换热器5内设有用于容纳冷却液的容纳腔，容纳腔分别通过管路与冷却液供给容器和冷却液回收容器相连，冷却液供给容器向容纳腔提供温度低于预设值的冷却液，冷却液在冷却液供给容器、换热器5及冷却液回收容器之间循环流动，不断向换热器5提供温度较低的冷却液。冷却液的温度可以为9°-14°，也可以根据切割线或硅棒的性能进行设定。
换热器5内还设有供切割液流过的切割液通道，切割液通道穿设于容纳空间内，以使冷却液包覆切割液通道，在冷却液与切割液之间进行热交换，冷却液吸收切割液的热量，以降低切割液的温度。
一种具体的实现方式：换热器5包括箱体，箱体内形成有容纳腔。箱体上开设有与容纳腔连通的冷却液入口和冷却液出口，冷却液入口通过管路与冷却液供给容器51相连，冷却液出口与冷却液回收容器52相连。
容纳腔内还设有切割液通道，且在箱体上设置有与切割液通道连通的切割液入口和切割液出口。切割液入口通过管路与过滤容器4相连，切割液出口通过管路与喷淋器6相连。
容纳腔内的冷却液包覆于切割液通道的外侧，流经切割液通道内的切割液与冷却液进行热交换实现冷却降温。
一种实现方式：冷却液入口和冷却液出口、切割液入口和切割液出***叉设置，以使切割液通道沿矩形箱体的对角线方向延伸，延长切割液在换热器5内流过的时间，进而提高冷却效果。
在冷却液的流动管路上设置有电动阀，通过调节电动阀的开度以调节冷却液的流量。
本实施例提供一种过滤容器4的实现方式：过滤容器4包括：过滤桶体，过滤桶体的上部设有切割液出口，底部设有切割液入口。以使切割液从底部的切割液入口进入过滤桶体，并从上部的切割液出口排出。过滤桶体内设置有过滤袋，用于对切割液进行过滤，滤除杂质、固体颗粒等。过滤袋可以采用刚性材料制成，例如：不锈钢材料；也可以采用软性材料制成。
进一步的，还采用流量计7设置在换热器5与喷淋器6之间的管路上，用于检测管路中的切割液流量。

在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接或可以互相通讯；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或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中的具体含义。
尽管已描述了本申请的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本申请范围的所有变更和修改。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
