Description

热水循环泵 技术领域
本发明涉及一种循环泵，尤其涉及一种热水循环泵。
背景技术
热水循环电泵特别是永磁同步电机热水循环泵，具有高效节能、低噪音、变频运行的优点，得到广泛应用。此类电泵需要有电子器件壳体(接线盒)用于容纳电机控制装置(把控驱动控制器/驱动板、电源连接件/电连接等)；电机驱动控制器包括微处理器和功率元件，通常功率器件需要设置散热器。
热水循环泵在泵送热水时在电机壳体和泵体上形成高温，应尽可能的避免高温通过辐射或传导进入接线盒(特别是功率电子器件设置在接线盒中时)，需要将产生的热量及时、有效、安全地排出。
在使用过程中，接线盒内部的电气和/或电子元件也会产生热量，能否及时有效将电气和/或电子元件产生的热量进行散热，不仅与散热面积的大小有关，还与散热器的布局和内部元器件的布局有着很大的关联。
随着永磁变频泵功率的增加，功率元件的功率越来越大，驱动板的体积和电气和/或电子元件数量都在增大，需要的装配空间也越来越大。热水循环泵又受到应用场合的限制，需要有较小的整体尺寸，在泵壳体和电机壳体尺寸一定的前提下，则限制了接线盒的尺寸。
为了使热水循环泵产生的热量及时排出，又为了使接线盒内部产生的热量及时排出，需要优化接线盒的结构及设置方式，然而现有的接线盒结构及设置方式难以满足泵功率日益增加的热水循环泵的需求。因此，需要设计出一个布局紧凑、散热效果良好的热水循环泵是非常有必要的。
发明内容
本发明的目的在于解决现有技术存在的上述问题而提供一种热水循环泵，改进接线盒的结构，既扩大接线盒的容纳空间，又满足结构紧凑、散热效果良好的要求，充分利电机周边空间，满足泵和接线盒的散热，又满足产品的整体尺寸要求。
本发明的上述技术目的主要是通过以下技术方案解决的：热水循环泵，包括泵壳体、设置在所述泵壳体中并由电动机驱动的泵叶轮，所述电动机设置在泵叶轮的轴向，所述电机壳体与所述泵壳体通过法兰对连接，所述电机壳体外设置接线盒，所述接线盒用于容纳电机控制装置的电气和/或电子元件以及电机的电连接，其特征在于所述接线盒至少具有三个空 间，包括一个轴向空间和两个径向空间，两个所述的径向空间都与所述的轴向空间连通。
本文涉及的轴向是指相对于泵叶轮转动轴基本上垂直延伸的方向；径向是指平行于泵叶轮转动轴延伸的面。
在本技术方案中，改进接线盒的结构，采用具有至少三个空间的接线盒，使三个空间周向分布在电机周边，充分利电机周边空间，形成紧凑的效果，满足产品的整体尺寸要求。同时，至少具有三个空间(当然，如果设置三个径向空间也是可行)，用于容纳电气和/或电子元件以及电机的电连接，扩大了接线盒的容纳空间，满足泵功率日益增加的要求。而且，周向分布于电机周边，具有较大的散热面积及散热空间，满足散热效果良好的要求。具有间隙防止接线盒和电机壳体直接接触，防止两者之间的热传导，减小两者之间的散热干扰。
作为对上述技术方案的进一步完善和补充，本发明采用如下技术措施：所述接线盒的内侧与所述电机壳体的外表面间距配合。形成的间距，使接线盒与电机壳体之间的间隔空间形成对流通道，使电机壳体上的热量和接线盒上的热量通过对流的方式及时、有效、快速排出，提高了散热效果。
关于两个径向空间的设置方式，至少有以下两种方案：
第一种方案：两个所述的径向空间连接构成L形，通过一隔板分隔两所述的径向空间，使两个所述的径向空间形成为两个独立空间，减小两个径向空间之间的热流通，减少两个径向空间内的热量对彼此的影响。两个径向空间又都与轴向空间连通，用于方便使径向空间的元器件与轴向空间的元器件形成电气或者电线连接。
在两个所述的径向空间连接构成L形的方案中，两个所述的径向空间与所述轴向空间之间设有留空结构，所述留空结构贯穿所述接线盒，形成工具操作通腔，用于拆装所述接线盒固定在所述电机壳体上的连接件。在拆装接线盒时，操作工具能够通过留空结构的操作通腔作用于连接件，使连接件从接线盒上分离或使连接件固定接线盒和电机壳体。
第二种方案：两个所述的径向空间分别设置在所述轴向空间相对的两侧，使所述接线盒呈U形。两径向空间的上端都与轴向空间联通，两径向空间彼此相对相对独立，防止两个径向空间内的热量对彼此的影响。呈U形结构的接线盒，在接线盒连接到电机壳体时，能够方便的操作。
所述泵壳体上设置进水口和出水口，并在所述进水口和出水口部位分别设置第一管螺纹和第二管螺纹，两个所述的径向空间的悬空端在轴向方向上与所述第一管螺纹和第二管螺纹间隔配合。也就是说，降低了对接线盒装配方向的限制，接线盒在轴向能够根据需要旋转90度安装(如果接线盒和电机壳体上设有合适的连接部位，在轴向方向任意旋转接线盒)， 都能够顺利安装接线盒，不与进、出水口处的第一管螺纹和第二管螺纹发生接触，防止第一管螺纹和第三法兰顶起接线盒，能够通过连接件稳定的固定接线盒到电机壳体上。
所述轴向空间的径向侧壁上设置电源进线插孔，所述电源进线插孔与两个所述径向空间间距设置，用于使所述电源进线插孔远离所述电气和/或电子元件位置设置，所述电源进线插孔用于设置电缆锁头。
所述电机壳体的端部设置上凸的连接柱，所述轴向空间的底部通过连接件固定在连接柱上，使所述连接盒固定在所述电机壳体上。设置连接柱，一方面用于形成连接件的连接基座，另一方面用于顶起接线盒，使接线盒上的轴向空间的底部与电机壳体的外表面之间具有间距，防止散热干扰。
所述轴向空间的外侧设置轴向开口，所述轴向开口设置操作面板，所述操作面板形成所述轴向空间的盖板；操作面板设置在轴向空间的上部轴向开口，方便操作、及观察，另一方面，又作为盖板使用，有利于简化结构，同时还有利于降低成本。
两个所述的径向空间为第一径向空间和第二径向空间，所述第一径向空间和第二径向空间的外侧分别设置第一径向开口和第二径向开口，所述第一径向开口和第二径向开口分别设置第一散热器和第二散热器，所述第一散热器和第二散热器分别形成所述第一径向空间和第二径向空间的盖板。由于轴向空间设置操作面板，为了防止操作面板长期使用在高温环境，以利于提高操作面板的使用寿命，通常来说，发热量大的元器件设置在第一径向空间和第二径向空间，为了能够快速散热，分别设置第一散热器和第二散热器，同时，为了结构简化，第一散热器和第二散热器又分别形成为两个盖板用于封闭第一径向空间和第二径向空间。功率元器件
所述第一径向空间和第二径向空间内分别设置第一驱动板和第二驱动板，所述第一驱动板和第二驱动板上朝向对应散热器的一面设置功率元器件，所述第一驱动板和第二驱动板上远离对应散热器的一面设置控制元器件，所述功率元器件分别贴合所述第一散热器和第二散热器的内表面。第一驱动板和第二驱动板上的发热量大的元器件(功率元器件)贴合在第一散热器和第二散热器上，有利于快速散热，提高驱动板及其上的电气和/或电子元件(尤其提高功率元器件的使用寿命)使用寿命。

具体实施方式
下面通过实施例，并结合附图，对本发明的技术方案作进一步具体的说明。
实施例：热水循环泵，如图1-3所示，它包括泵壳体1、设置在所述泵壳体1中并由电动机驱动的泵叶轮，所述电动机设置在泵叶轮4的轴向，所述电机壳体2与所述泵壳体1通过法兰对连接，所述电机壳体1外设置接线盒3，所述接线盒3用于容纳电机控制装置的电气和/或电子元件以及电机的电连接，所述接线盒3至少具有三个空间，包括一个轴向空间31和两个径向空间32、33，两个所述的径向空间都与所述的轴向空间连通。
本文涉及的轴向是指相对于泵叶轮转动轴基本上垂直延伸的方向；径向是指平行于泵叶轮转动轴延伸的面。
在本技术方案中，改进接线盒的结构，采用具有至少三个空间的接线盒，使三个空间周向分布在电机周边，充分利电机周边空间，形成紧凑的效果，满足产品的整体尺寸要求。同时，至少具有三个空间(当然，如果设置三个径向空间也是可行)，用于容纳电气和/或电子元件以及电机的电连接，扩大了接线盒的容纳空间，满足泵功率日益增加的要求。而且，周向分布于电机周边，具有较大的散热面积及散热空间，满足散热效果良好的要求。具有间隙防止接线盒和电机壳体直接接触，防止两者之间的热传导，减小两者之间的散热干扰。
在本实施例中，接线盒具有一个轴向空间31、和两个径向空间32、33，两个径向空间 分布为第一径向空间32和第二径向空间33。
所述接线盒3的内侧与所述电机壳体2的外表面间距配合。形成的间距，使接线盒与电机壳体之间的间隔空间形成对流通道，使电机壳体上的热量和接线盒上的热量通过对流的方式及时、有效、快速排出，提高了散热效果。
关于两个径向空间的设置方式，至少有以下两种方案：
第一种方案：如图1和图4所示，两个所述的径向空间32、33连接构成L形，通过一隔板20分隔两所述的径向空间，使两个所述的径向空间形成为两个独立空间，减小两个径向空间之间的热流通，减少两个径向空间内的热量对彼此的影响。两个径向空间又都与轴向空间连通，用于方便使径向空间的元器件与轴向空间的元器件形成电气或者电线连接。采用L形结构的径向空间32、33还有利于方便电线连接。本技术方案为优选方案。
如图1所示，在两个所述的径向空间32、33连接构成L形的方案中，两个所述的径向空间与所述轴向空间之间设有留空结构10，所述留空结构10贯穿所述接线盒，形成工具操作通腔，用于拆装所述接线盒3固定在所述电机壳体2上的连接件。在拆装接线盒时，操作工具能够通过留空结构的操作通腔作用于连接件，使连接件从接线盒上分离或使连接件固定接线盒和电机壳体。
第二种方案：两个所述的径向空间分别设置在所述轴向空间相对的两侧，使所述接线盒呈U形。两径向空间的上端都与轴向空间联通，两径向空间彼此相对相对独立，防止两个径向空间内的热量对彼此的影响。呈U形结构的接线盒，在接线盒连接到电机壳体时，能够方便的操作。
如图1所示，所述泵壳体1上设置进水口11和出水口12，并在所述进水口11和出水口12部位分别设置第一管螺纹13和第二管螺纹14，两个所述的径向空间32、33的悬空端在轴向方向上与所述第一管螺纹13和第三法兰14对间隔配合。也就是说，降低了对接线盒装配方向的限制，接线盒在轴向能够根据需要旋转90度安装(如果接线盒和电机壳体上设有合适的连接部位，在轴向方向任意旋转接线盒)，都能够顺利安装接线盒，不与进、出水口处的第一管螺纹和第二管螺纹发生接触，防止第一管螺纹和第三法兰顶起接线盒，能够通过连接件稳定的固定接线盒到电机壳体上。
如图1所示，所述轴向空间的径向侧壁上设置电源进线插孔25，所述电源进线插孔与两个所述径向空间间距设置，用于使所述电源进线插孔远离所述电气和/或电子元件位置设置，所述电源进线插孔25用于设置电缆锁头26。
如图3所示，所述电机壳体2的端部设置上凸的连接柱21，所述轴向空间31的底部通 过连接件23固定在连接柱21上，使所述连接盒3固定在所述电机壳体2上。设置连接柱，一方面用于形成连接件的连接基座，另一方面用于顶起接线盒，使接线盒上的轴向空间的底部与电机壳体的外表面之间具有间距，防止散热干扰。
如图4和5所示，所述轴向空间31的外侧设置轴向开口311，所述轴向开口311设置操作面板12，所述操作面板12形成所述轴向空间31的盖板；操作面板设置在轴向空间的上部轴向开口，方便操作，另一方面，又作为盖板使用，有利于简化结构，同时还有利于降低成本。
所述第一径向空间32和第二径向空间33的外侧分别设置第一径向开口321和第二径向开口331，所述第一径向开口321和第二径向开口331分别设置第一散热器13和第二散热器14，所述第一散热器13和第二散热器14分别形成所述第一径向空间32和第二径向空间33的盖板。由于轴向空间设置操作面板，为了防止操作面板长期使用在高温环境，以利于提高操作面板的使用寿命，通常来说，发热量大的元器件设置在第一径向空间和第二径向空间，为了能够快速散热，分别设置第一散热器和第二散热器，同时，为了结构简化，第一散热器和第二散热器又分别形成为两个盖板用于封闭第一径向空间和第二径向空间。
所述第一径向空间32和第二径向空间33内分别设置第一驱动板15和第二驱动板16，所述第一驱动板15和第二驱动板16上朝向对应散热器的一面设置功率元器件，所述第一驱动板和第二驱动板上远离对应散热器的一面设置控制元器件，所述功率元器件分别贴合所述第一散热器13和第二散热器14的内表面。第一驱动板和第二驱动板上的发热量大的元器件(功率元器件)贴合在第一散热器和第二散热器上，有利于快速散热，提高驱动板及其上的电气和/或电子元件(尤其提高功率元器件的使用寿命)使用寿命。
对于第一散热器13和第二散热器14上的第一散热片和第二散热片来说，第一散热片和第二散热片为一一对应的方式设置，并且轴向齐平的方式设置。
对于操作面板12来说，如图6所示，包括盖板18，设置在盖板18内侧的显示和操作板17，设置在盖板18外侧的贴膜19。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明。在上述实施例中，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
