Description

用于医用加速器的散热装置 技术领域
本发明实施例涉及医疗设备，特别涉及一种用于医用加速器的散热装置。
背景技术
常规加速器的旋转角度一般为360度。在这种加速器中，一般将散热装置安装于一个专用的设备间内，通过水管将散热装置与加速器的水循环系统相连。水管通过盘线器从固定机架引导到旋转机架。
对于可连续旋转的医用加速器而言，无法通过盘线器将水管从固定机架引导至旋转机架，一般的解决方案是在加速器旋转机架上直接布置散热器，通过风扇直吹散热器。由于医用加速器的发热量很大，对散热器的散热能力要求非常高，为了增大散热能力，需要使用多个高转速的风扇。这些高转速风扇在运行过程中会产生非常大的噪音。此外，加速器工作时的温度在35度左右，与室温的温差较小，不易散热，且在加速器机壳封装后，加速器内部的热量更加难以散发出去。为达到较好的散热效果，对于医院机房的温度要求非常苛刻，比如某医用加速器要求机房的温度必须在23℃以下，而一般舒适的室温在26度左右。
因此，目前医用加速器的散热能力非常有限，并且由于环境的苛刻要求限制了其使用范围，亟需提供新的散热方案。
发明内容
鉴于现有技术中存在的问题，本发明提供一种用于医用加速器的散热装置，其特征在于，包括能够被固定地连接于加速器并随着所述加速器旋转的散热单元；具有能够容纳所述散热单元的腔室的框架单元；设置于所述框架单元外部或内部的至少一个制冷单元；所述框架单元内具有至少一条内风道，以使得所述制冷单元产生的冷空气能够经由所述内风道吹向所述散热单元；能够容纳所述加速器、散热单元和框架单元的外壳，所述外壳形成外风道，以使得吹向所述散热单元的冷空气能够在所述的内风道和外风道中形成循环。
本申请提供的用于医用加速器的散热装置能够使冷空气在的内风道和外风道中形成循环，避免医疗时吹向患者，影响人体舒适度。
在本发明的一些实施方式中，所述框架单元和所述散热单元有结合状态和分离状态，当所述散热单元被固定地连接于所述加速器时，所述框架单元和所述散热单元处于分离状态。
在本发明的一些实施方式中，所述的散热装置包括设置于所述框架单元底部的移动单元；以及和所述移动单元匹配的导向单元，以使得当所述框架单元和所述散热单元处于结合状态时，所述框架单元能够承载着所述散热单元沿所述导向单元移动；当所述框架单元和所述散热单元处于分离状态时，所述框架单元和所述散热单元的位置能够被调整。
本发明提供的散热装置的散热单元和框架单元具有分体结构，框架单元内具有制冷单元，能够起到良好的散热效果，同时框架单元能够在散热单元移出检修时起到承载作用。进一步地设置了移动单元和导向单元，以便于维修人员将散热单元随同框架单元移出。
在本发明的一些实施方式中，所述的散热装置包括所述框架单元内具有多条内风道；设置于多条所述内风道中的风压调节板和风压传感器；所述风压调节板能够根据所述风压传感器获取的风压值调整所述内风道中的风压，以使得所述多条内风道中的风压相等或者相近。
本发明散热装置中的风道间彼此独立，因此由多条内风道吹向散热单元表面的冷空气平均分布，有利于使其全面降温，以达到最佳的散热效率。
在本发明的一些实施方式中，所述散热单元包括能够固定地连接于所述加速器的散热器以及固定于所述散热器表面的循环水箱。
在本发明的一些实施方式中，所述循环水箱包括沿环状排布的多个小水箱；依次连接各个所述小水箱的连通管；设置于所述小水箱上或所述连通管上的水位检测装置；设置于所述小水箱或所述连通管上的出水口和进水口。
在本发明的一些实施方式中，设置于所述循环水箱上的自动泄压阀；所述自动泄压阀包括：具有阀门的泄压阀；具有第一活塞的第一液压缸，所述第一活塞的活塞杆伸出所述第一液压缸并与所述阀门相关联，以使得根据所述第一活塞的运动能够控制所述阀门的开启或关闭；通过螺母固定地套设于所述第一活塞活塞杆上的弹簧，以凭借所述弹簧使所述第一活塞的活塞杆保持压缩状态；和所述第一液压缸相互垂直布置的具有第二活塞的第二液压缸，所述第二活塞的活塞杆伸出所述第二液压缸并与所述第一活塞相关联；以及 设置于所述第二液压缸内的质量球，所述质量球凭借自身重力使得所述第二活塞的活塞杆保持向外伸出的趋势。
由于循环水箱的水管会在加速器的主要元器件内部通过，带走加速器元器件工作产生的热量。若水箱中存在空气，会影响加速器元器件的正常工作，甚至对其造成损坏。通过安装自动泄气阀，在加速器旋转，带动循环水箱一起旋转的情况，可以排出水箱中空气，保证散热器正常工作不受损。循环水箱旋转时，当自动泄气阀位置为直立朝上状态时，质量球的重力会大于弹簧的压力，将阀门打开，使得水箱中的气体可以排出；当循环水箱旋转到自动泄气阀不处于直立状态时，质量球的重力对弹簧的压力不足以将阀门打开，阀门为关闭状态，可以保证水箱中液体不会泄露。
在本发明的一些实施方式中，所述循环水箱包括环状的第一循环水箱以及环状的第二循环水箱，所述第一循环水箱位于所述第二循环水箱的外围；所述第一循环水箱和所述第二循环水箱通过连通管串联。
在本发明的一些实施方式中，所述第一循环水箱包括沿环状排布的多个第一小水箱；依次连接各个所述第一小水箱的第一连通管；设置于所述第一小水箱上或所述第一连通管上的第一水位检测装置；设置于所述第一小水箱或所述第一连通管上的第一出水口和第一进水口；所述第二循环水箱包括：沿环状排布的多个第二小水箱；依次连接各个所述第二小水箱的第二连通管；设置于所述第二小水箱上或所述第二连通管上的第二水位检测装置；设置于所述第二小水箱或所述第二连通管上的第二出水口和第二进水口；所述第一出水口和所述第二进水口通过第三连通管连通；或所述第二出水口和所述第一进水口通过第三连通管连通。

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
实施例一
如图1～6所示，本实施例提供一种用于医用加速器的散热装置，主要包括散热单元2、框架单元3和外壳4。散热单元2能够被固定地连接于加速器1上，并随着加速器1旋转。在本实施例中，加速器1大致呈圆柱体，散热装置位于加速器1主体的后面并与之固定连接。散热单元2与框架单元3之间采用转动副相连，且此转动副的旋转中心与医用加速器旋转机架的旋转中心同轴。框架单元3和散热单元2具有结合状态和分离状态。在正常工作时，散热单元2与医用加速器1的旋转机架通过螺丝连接，在检修加速器时，可拆掉散热单元2与加速器1主体的螺丝，以便将散热装置与医用加速器分离。框架单元3具有能够容纳散热单元2的腔室，其内部至少具有一条内风道32。框架单元3还包括一个可以设置在其内部或者外部的制冷单元31，该制冷单元31产生的冷空气能够经由内风道32吹向散热单元2。
在本实施例中，框架单元3具有多条内风道32，每条内风道32中设置有风压调节板和风压传感器，风压调节板能够根据风压传感器获取的风压值 调整内风道32中的风压，以使得多条内风道32中的风压相等或者相近。制冷单元31的数量和内风道32的数量相等，且内风道间彼此独立。因此由多条内风道32吹向散热单元2表面的冷空气平均分布，有利于使其全面降温，以达到最佳的散热效率。此外，散热单元进风侧与出风侧可以分别布置温感器，对散热单元的散热状态做出评估。制冷单元31可以采用空调室内机。
本实施例中散热装置包括了外壳4。该外壳4能够容纳加速器1、散热单元2和框架单元3。在外壳4的内部形成了外风道41，以使得吹向散热单元2的冷空气能够在外风道41中循环，然后缓慢散去。这样设置可以使经过散热单元2的冷空气在外壳4的外风道41中自循环，避免医疗时吹向患者，影响人体舒适度。
继续参照图1～6，散热单元2包括能够固定地连接于加速器1的散热器21以及固定于散热器21表面的循环水箱22。本实施例中散热器21呈环状，因此循环水箱22也呈环状，且固定于散热器21的外端。
如图7所示，循环水箱22包括沿环状排布的多个小水箱、依次连接各个小水箱的连通管、设置于小水箱上或连通管上的水位检测装置、设置于小水箱或连通管上的出水口和进水口。
如图8和9所示，循环水箱22上设置有自动泄压阀23，该自动泄压阀23包括具有阀门231的泄压阀232，具有第一活塞233的第一液压缸234，第一活塞233的活塞杆伸出第一液压缸234并与阀门231相关联，以使得根据第一活塞233的运动能够控制阀门231的开启或关闭，通过螺母235固定地套设于第一活塞233活塞杆上的弹簧236，以凭借弹簧236使第一活塞233的活塞杆保持压缩状态(向第一液压缸234内)。
该自动泄压阀23还包括具有第二活塞237的第二液压缸238，第二活塞237的活塞杆伸出第二液压缸238并与第一活塞233相关联，以及设置于第二液压缸238内的质量球239，质量球239凭借自身重力使得第二活塞237的活塞杆保持向外伸出的趋势。
由此，本领域技术人员应当能够理解，由于循环水箱的水管会在加速器的主要元器件内部通过，带走加速器元器件工作产生的热量。若水箱中存在空气，会影响加速器元器件的正常工作，甚至对其造成损坏。通过安装自动泄气阀，在加速器旋转，带动循环水箱一起旋转的情况，可以排出水箱中空气，保证散热器正常工作不受损。循环水箱随加速器旋转时，当自动泄气阀位置为直立朝上状态时，质量球的重力会大于弹簧的弹力，将阀门打开，使得水箱中的气体可以排出；当自动泄气阀未处于直立状态时，质量球的重力对弹簧施加的压力小于弹簧自身的弹力，不足以将阀门打开，阀门为关闭状态，可以保证水箱中液体不会泄露。
实施例二
参照图1和图5所示，本实施例与实施例一不同之处在于循环水箱22包括环状的第一循环水箱221以及环状的第二循环水箱222，第一循环水箱221位于第二循环水箱222的外围。第一循环水箱221和第二循环水箱222通过连通管串联。
其中，第一循环水箱221包括沿环状排布的多个第一小水箱；依次连接各个第一小水箱的第一连通管；设置于第一小水箱上或第一连通管上的第一水位检测装置；设置于第一小水箱或第一连通管上的第一出水口和第一进水口。第二循环水箱222包括沿环状排布的多个第二小水箱；依次连接各个第二小水箱的第二连通管；设置于第二小水箱上或第二连通管上的第二水位检测装置；设置于第二小水箱或第二连通管上的第二出水口和第二进水口；第一出水口和所述第二进水口通过第三连通管连通；或第二出水口和第一进水口通过第三连通管连通。
实施例三
参照图8～11，本实施例与实施例一和二的区别在于，加速器1大致呈圆柱体，散热单元2能够套装在加速器1的外围并与之固定连接。
框架单元3和散热单元2具有结合状态和分离状态。当加速器1工作时，散热单元2被固定在加速器1上并随之转动且旋转轴心相同，散热单元2和框架单元3处于分离状态，制冷单元31经由内风道32向散热单元2吹送冷空气。当加速器1停止工作时，检修人员可以将散热单元2从加速器1上拆卸下来，再将其和框架单元3通过螺丝固定连接后移出检修。实际上，框架单元3充当了承载散热单元2的载体。
为了方便固定在一起的散热单元2和框架单元3的移动，本实施例中的框架单元3还包括了设置于其底部的移动单元33以及和移动单元33匹配的导向单元34。具体而言，移动单元33可以采用滚轮，导向单元34可以采用导轨。导轨的铺设方向决定了框架单元3的移动方向。由此，当框架单元3和散热单元2处于结合状态时，框架单元3能够承载着散热单元2沿导向单元34移动。
实施例四
本实施例与实施例一、二和三的区别在于当框架单元3和散热单元2处于分离状态时，即散热单元2和加速器1固定连接在一起时，框架单元3仍 然可以凭借移动单元33沿着移动单元33运动，以使得框架单元3相对于散热单元2的位置能够被调整，进而促使内风道32可以更好的对准散热单元2以为其输送冷空气。
实施例五
参照图12-13所示，本实施例与实施例一和实施例三不同之处在于制冷单元31设置于框架单元3的外部，且通过额外的通风管道5和框架单元3中的内风道32连接。因此，制冷单元31可以布置在加速器所在房间之外的地方。此外，通风管道5可以不与制冷单元31连接，而是将其设置于风口，依靠自然风的吹入为散热单元2降温。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
