Description

具有一激光器单元，及用于该激光单元的冷却装置的一液体容器的激光设备
技术领域
本发明涉及一种根据权利要求1所述的一激光设备。本发明进一步涉及一种根据权利要求10所述的在激光设备中使用的用于冷却液体的液体容器。
背景技术
激光设备包括至少一用于生成激光的激光单元，以及用于冷却该激光单元的冷却装置，该冷却装置包括一通道配置，通过该通道配置一冷却液被循环从而将热量转移出激光单元。
对于激光器单元，特别对于气体激光器来说，设有一冷却设备是已知的，从而由在气体激光器的谐振管中分布的气体产生的热量将被转移出。为了达成高的激光束质量，需要将激光器单元的温度保持在一规定范围内。通常冷却装置包括有用于将冷却液穿过在激光设备的热量产生部件中的管道、管体以及其他通道的泵。
即使在封闭的冷却线路中，仍存在一定由蒸发、渗漏或扩散产生的散热液的损失。
因而，需要时常检查系统中散热液的高度并重新注满液体。在已知的设备中，通过在设备的壳体上的一个开口，液体从一个瓶子中被重新注满。然而，若不新鲜的液体、错误的液体，或被污染的液体被注入系统中，可能造成热量转移的不充分、阻塞或是腐蚀。这通常将导致设备的寿命变短。
发明内容
本发明的目的旨在确保激光器设备的可靠冷却。
本发明的目的可通过包括有权利要求1技术特征的激光设备来解决。本发明的目的进一步可通过包括有权利要求10技术特征的液体容器来解决。在从属权利要求中则给出了各优选的实施例。
激光设备的特征在于，提供有一用于可分离地持有一液体容器的安装零件，该安装零件包括一用于以液体密封的方式与液体容器的第二连接部件连接的第一连接部件，且安装零件与通道配置连接。
本发明的一基本构想在于提供一用于通过一特定冷却液容器对冷却装置供给规定的散热液。可避免错误的或不合适的液体的注入。进一步地，由于本发明的冷却液容器直接连接至系统的注入部，不需要在冷却装置及一外部散热液储藏器间的连接线。液体容器允许补偿激光器单元的冷却装置中的散热液流体的损失。有利地，连接部件在安装零件上提供一液体密封连接并提供液体容器的支持。注入部，即用于散热液的液体容器的出口，在液体容器及通道配置间提供有一稳定的支持。优选地，安装零件的第一连接部件包括允许仅一种类型的容器与正确的冷却液连接的特定轮廓部。
进一步地，在注液操作中，散热液意外渗漏的风险被降低。液体的渗漏可能造成电子激光设备的严重损伤。因而，对于操作者及激光设备来说，重新注液变得更为简单及安全。
在本发明中，短语“液体”。“冷却液”，“散热液”及“散热液流体”是可互换的。散热液可从液体容器中，通过第一及第二连接部件，传送至通道配置，或通道配置的一个通道中。
在一特别优选的实施例中，第一连接部件包括一闭合装置，其中液体容器及通道间的流体连接在液体容器分离时闭合。在液体容器从第一连接部件分离时，闭合装置防止散热液的渗漏。当液体容器分离时，注入部自动闭合。这可通过例如一设计为一阀闭合部或负载弹簧的闭合板的第一连接部件来实现。另一方面，当安装零件的第一连接部件与液体容器的第二连接部件啮合时，闭合装置处于开放状态允许散热液通过。
第二连接部件与该安装零件的第一连接部件紧密地相配合。这两个连接部件的连接可使得液体容器至安装零件的连结改善。连接的种类通常可为任何种类。优选地，通过这两个连接部件可形成插塞连接或螺纹连接，其中安装零件上的第一连接部件是母连接部，而液体容器上的第二连接部件设计为公连接部。
根据本发明，该液体容器可设计为在第二连接部件处设有密封的一存储盒（cartridge）。密封可防止在存储盒中储存的液体的渗漏。存储盒是可传送的，其中其形状及大小均不是固定的。而且，存储盒中密封的配置确保了常规的更换。存储盒可被注入规定量的液体，避免冷却系统装得太满。完整的密封保证了在存储盒中注入规定量的新鲜液体。
在一本发明特别优选的实施例中，该密封通过一可弯曲的薄箔板形成。避免任何可以损害存储盒中的液体组合物的不需要颗粒的摄入或污染。在第一次使用时，薄的密封将会被破坏，从而将可轻易辨识并避免旧液体的重复使用。
根据本发明，优选地，安装零件包括用于刺穿该液体容器的密封的刺穿装置。其具有在存储盒与安装零件连接时，自动打开密封的优势。刺穿装置可包括一针状物，该针状物包括一中心通路，通过该中心通路，液体从存储盒的内部转移至与该安装零件连接的通道配置。
特别优选地，在液体容器上设置有用于储存有关该液体容器及液体容器中的冷却液信息的信息储存装置，特别为一微芯片。信息可包括有关容器中储存液体的相关数据，例如液体的组分，生产日期等。因而可通过该储存装置中储存的信息确认液体容器。此外，可提供一用于检测或接收信息的检测单元。优选地，信息存储装置被设计为一微芯片或一发射器芯片。在将液体注入容器后，关于该液体的信息可保存在微芯片中，用于液体容器的内容的具体文件记录。保存在信息存储装置中的数据同样可包括包含在液体容器中的散热液的量。
为了阅读储存在信息储存装置中的信息，优选地，安装零件包括一电接触面。这些电接触面接触液体容器的某些区域，当安装零件持有液体容器时。
优选地，提供有用于阅读信息储存部上的信息的阅读器及评估单元，其可基于阅读信息允许来自该液体容器的冷却液的注入。
基于阅读器阅读出的信息，设备的评估单元可识别存诸装置上的数据。基于接收到的信息，评估单元打开注入部的闭合装置或使闭合装置保持闭合。这保证了仅仅是来自正确的容器的合适的液体可被注入冷却系统中。因而，避免了错误的液体进入冷却装置的通道配置中。进一步地，评估单元可确定在冷却装置和/或容器中冷却液的注入液位。若液体液位下降低于确保适当散热液供应的规定液位，信号单元可通过评估单元激活。激活的信号展示给操作者从而使用一新的液体容器。
在本发明的另一个实施例中，优选地，在通道配置中，放置有至少一个用于使冷却液在该通道配置中循环的泵。该至少一个泵具有使冷却液在通道配置中循环的功能从而将由激光单元产生的多余的热量转移，并将加热后的冷却液传递给用于冷却冷却液至所需操作温度的热交换器。此外，若液体容器与该通道配置中的注入部连接，来自液体容器的冷却液也可通过至少一个泵被吸入通道配置中。
本发明的液体容器的特征在于，液体容器被设计为一存储盒，并包括有用于存储有关该液体容器及该液体容器中的冷却液信息的信息储存部件。存储盒的设计确保了具有紧凑设计的充足的冷却液提供且其易于操作。进一步地，信息储存部件包括有有关注入在存储盒中的冷却液的重要信息，通过信息储存部件，可达成冷却液的良好使用，且操作可靠性高。
本发明将结合附图中所示的优选实施例进行进一步描述。
附图说明
图1是本发明存储盒的一实施例的结构示意图；
图2是本发明激光设备的一安装零件的实施例的结构示意图；
图3是根据本发明，激光设备的一安装零件及一存储盒的实施例的结构示意图；以及
图4是根据本发明，一激光设备的实施例的结构示意图。
附图中的等效部件分别用相同的附图标记标示。
具体实施方式
本发明首先将参考图1及图2进行描述。在图1中，示出了用于容纳冷却液的液体容器或存储盒50的结构示意图。图2示出了安装零件46，在安装零件46上可安装存储盒50。安装零件46用于释放储存的冷却液。
参考图1，存储盒50由一矩形的基体51组成，基体51包括有一液体储存器，其内注有用于冷却装置的冷却液。在存储盒前侧53的下部区，设置有一套筒状连接部件44。连接部件44在下文也被称为第二连接部件44。其适应于与另一连接部件，优选地为与图2中，安装零件46的圆柱形第一连接部件42相连接。第二连接部件44设计为一母连接部件。第二连接部件44的排放开口由一密封箔片55密封。密封箔片55防止存储盒50中的液体渗漏。一完整的密封箔片50表示存储盒50是未使用的。进而，密封箔片55防止存储盒50中储存的冷却液的挥发。
为了使用在存储盒50中储存的冷却液从而为激光设备的冷却装置30提供冷却液，通过存储盒50的第二连接部件44，存储盒50与第一连接部件连接，其中第一连接部件42被设计为一与第二连接部件44中紧密相配合从而形成一刚性连接（positiveconnection）的公连接部件。如图2所示，刺穿装置48被设置在第一连接部件42的中心从而刺穿密封箔片55以使得储存的冷却液在连接部件42，44间流动。
安装零件的第一连接部件42可同样被设计为持有存储盒50，从而在第一连接部件42上不需进一步的用于持有存储盒50的紧固设备或安装设备。当通过连接部件42，44连接有存储盒50时，安装零件46防止冷却液泄漏。
安装零件46包括一阅读部件65，其可读出储存在微芯片60中的信息，微芯片60连结在存储盒50的基体51的一侧54上。阅读部件65与微芯片60的电连接通过安装零件46的电接触面以及存储盒50的电接触区域61建立。当存储盒50内注满该冷却液时，微芯片60包含有关在存储盒50中的冷却液的信息，其中信息被写在内存（memory）中。
当存储盒50通过连接部件42、44连接时，在微芯片60中储存的信息通过由安装零件46的电接触面66及存储盒50的电接触区域61形成的通信连结由阅读部件65读取。随后，被读出的信息从阅读部件65传输至一评估单元（图1及图2中未示出），该评估单元设置在安装零件46上。评估单元的作用在于确保储存在存储盒50中的冷却液对于冷却装置30来说是否是符合或合适的。若传送的信息与评估单元中的数据相符，则循环泵38接通且使得冷却液进入冷却装置30的通道配置35中。若传送的数据并不相符，则循环泵38保持关闭。因而不正确的冷却液进入通道配置35中被阻止，从而冷却装置30被保护。
图3所示为彼此连接的存储盒50及安装零件46。进一步地，其示出了评估单元70。用于传送冷却液的通道配置35中的一个通道可通过注入部46的液体连接器47被连接至注入部46。相似地，存储盒50可包括一用于连接通道配置中的一个通道从而建立闭合循环圈的液体连接器47。
图4所示为根据本发明，一激光设备10的一实施例的结构示意图。激光设备10包括一激光单元20，冷却装置30，存储盒50以及用于持有存储盒50的安装零件46。冷却装置30包括与激光单元20相连接，并形成一闭合回路(loop)的通道配置35。冷却液通过一循环泵38穿过闭合回路。通道配置35包括一通过安装零件46的连接部件与存储盒50的一注入部相连接的通道入口。通道入口用于通过将新鲜的冷却液从存储盒50经由安装部件46引导进入通道配置35中，来补偿在通道配置35中液体损失，液体损失由例如挥发或渗漏造成。
冷却装置30包括一与激光设备20相连结的一热交换器84。激光设备20的多余的热量通过冷却液吸收，该冷却液在通道配置35中转移。加热的冷却液通过穿过热交换器84被再次冷却。热交换器84包括至少一通风器87（ventilator），在图示的例子中，其具有两个通风器，用于产生空气流。热交换器84通过通道配置35的装置与激光设备20连接。
在一个实施例中（图中未示出），通过通道配置35，以及激光设备20及热交换器84一起形成闭合回路。在这种情形中，注入部46的液体连接器47在一通用的任意位置与通道配置连接。然而在图示的例子中，闭合的回路仅与存储盒50一起形成。也就是说，存储盒50包括一液体连接器47，从而冷却液在常规操作期间流动穿过存储盒50。
激光单元20包裹有用于产生激光束的一激光器或复数个激光器。激光单元20表现有一开口，经由该开口，激光束可离开激光单元20。
激光单元20可包括一带状输入（umbilicalinput），一连接电缆(umbilicalcable)可与其连接。连接电缆可包括有用于向激光单元20供给电力，控制信号及冷却液的电线，数据线，以及冷却线。
