具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
发明人发现，安装温度传感器100'的结构难以控制温度传感器100'伸入输水流道的深度，例如，图1所示，将温度传感器100'插接于换热器的测温孔101'内，且温度传感器100'伸入输水流道，再采用螺帽200'套接于温度传感器100'的外围，螺帽200'螺纹锁附固定于换热器主体，需在螺帽200'内侧填充导热硅胶300'，通过导热硅胶300'与温度传感器100'抵接，以固定温度传感器100'的位置，这种安装结构，难以精确控制温度传感器100'插接于入输水流道的深度，也难以维持温度传感器100'的安装稳定性。基于此，本申请实施例提供一种换热装置及热泵系统。
如图2所示，为本申请一种实施例提供的换热装置10的结构示意图，如图3所示，换热装置10包括板式换热器、套管换热器等。换热装置10用于水力模块，例如，换热装置10安装于水力模块箱体的容置腔内。
换热装置10包括换热主体100和探温组件200。换热主体100内部具有输水流道和冷媒流道。其中，输水流道和冷媒流道内分别流通有温度不同的流体，输水流道内的流体与冷媒流道内的流体的热量进行交换，以调控输水流道内的流体的温度。探温组件200用于获取输水流道内流体的温度，以便根据输水流道内流体的温度调控冷媒流道内流体的温度，进而调控从输水流道内输出的流体的温度在预设的温度范围。
换热主体100具有与输水流道连通的测温孔121，其中，换热主体100内的输水流道呈多段弯折，以便在有限的空间内使换热主体100具有更长流通长度的输水流道，以及便于调控输水流道内流体的温度。测温孔121可与输水流道的其中一部分直流段连通，且同轴设置，以便探温组件200穿设测温孔121伸至输水流道内。
如图4所示，换热主体100限定测温孔121的壁面包括定位面1211，定位面1211与测温孔121的轴向呈夹角。具体地，测温孔121包括与输水流道连通的第一流道段1212、与外部空间连通的第二流道段1213，定位面1211连接于换热主体100限定第一流道段1212的壁面和限定第二流道段1213的壁面之间。例如，第一流道段1212的流通面积小于第二流道段1213的面积，定位面1211垂直于测温孔121的轴向，或者，在第一流道段1212朝向第二流道段1213的方向，定位面1211至测温孔121的中心轴的面积逐渐增大。
探温组件200包括温度探头210和档位件220，温度探头210穿设测温孔121并伸至输水流道内，用于检测输水流道内流体的温度，档位件220安装于换热主体100并用于限定温度探头210的位置。具体地，温度探头210包括测温主体211和设于测温主体211的定位部212，例如，定位部212套接于温度探头210外围。测温主体211穿设测温孔121并伸至输水流道，例如，测温主体211呈杆状，便于测温主体211深入输水流道以探测输水流道内流体的温度。
测温主体211深入输水流道内时，定位部212位于测温孔121内，且定位部212与定位面1211抵接，档位件220固定于换热主体100且抵接于定位部212，例如，档位件220在测温孔121的轴向抵接于定位部212，将温度探头210固定于换热主体100，防止温度探头210从测温孔121脱除。
档位件220固定于换热主体100时，档位件220作用于定位部212背离定位面1211的表面，档位件220直接作用于定位部212并能够将定位件朝向定位面1211所在的一侧推送，直至定位部212抵接于定位面1211。其中，定位部 212可直接抵接于定位面1211，或者通过其他结构件抵接于定位面1211，例如，探温组件200还包括导热弹性件230，导热弹性件230设于定位面1211和定位部212之间，定位部212通过导热弹性件230抵接于定位面1211。本申请能够实现将温度探头210一步安装到位，并控制好温度探头210的测温主体211深入输水通道内的程度，提高测温主体211的安装稳定性，从而提高测温主体211探测输水流道内流体温度的准确性。
可选地，导热弹性件230套接于测温主体211外围，且导热弹性件230在测温孔121的轴向可形变。例如，导热弹性件230为导热硅胶弹性件或导热橡胶弹性件等。
换热主体100的外表面包括探测器安装面122，测温孔121开设于探测器安装面122，当换热装置10安装于水力模块的箱体内时，探测器安装面122可为换热主体100沿重力方向设置的表面，本申请对探测器安装面122的朝向不做限定，具体可根据实际需求进行选择。
定位部212设于测温孔121，且定位部212背离定位面1211的表面与探测器安装面122平齐，档位件220抵接于探测器安装面122，便于设计档位件220的结构使档位件220能够抵接于定位部212和探测器安装面122。
受限于换热主体100部分壁面的壁厚，测温孔121长度受限，可以理解的是，测温孔121越长，换热主体100限定测温孔121的壁面则能够更多地与定位部212相接触，提高温度探头210设于测温孔121处的安装稳定性。可选地，换热主体100包括换热箱110和探头定位部120，换热箱110具有输水流道和冷媒流道，探头定位部120具有测温孔121。换热箱110还具有与输水流道连通的插接口111，探头定位部120设于插接口111处且凸设于换热箱110的外表面，探头定位部120背离插接口111的表面形成探测器安装面122，可通过设计探头定位部120的尺寸，以设计测温孔121的深度，使定位部212位于测温孔121内时，探头定位部120与定位部212的接触面积合适，提高温度探头 210安装于换热主体100的安装稳定性。
可选地，定位部212的外周壁面包括至少呈角度设计的两部分，换热主体100限定测温孔121的壁面与定位部212的外周壁面贴合，以防止温度探头210绕测温孔121周向旋转。
档位件220固定于探头定位部120，其中，探头定位部120凸设于换热箱110外表面，还便于将档位件220固定于探头定位部120，便于组装。
如图3所示，档位件220的外周壁面开设有档位开口2201，档位开口2201沿测温孔121的轴向贯穿档位件220。组装时，可将档位件220置于测温孔121其中一侧，档位开口2201朝向温度探头210，沿垂直于测温孔121轴向的方向移动档位件220，直至档位件220分别与定位部212表面和探测器安装面122相接触，且测温主体211进入档位开口2201内，将档位件220固定于探测定位部212，即可完成组装将温度探头210固定，并使温度探头210伸入输水流道内的位置合适。
温度探头210穿设档位开口2201且与档位件220限定档位开口2201的壁面相接触，例如，温度探头210与档位件220限定档位开口2201的壁面贴合或抵接，以进一步提高温度探头210的安装稳定性。
可选地，温度探头210置于档位开口2201内的部分的外轮廓呈圆形；或者，温度探头210置于档位开口2201内的部分的外表面包括至少呈角度设置的两部分，如此，以防止温度探头210绕测温孔121周向旋转。
档位件220包括档位部221和档位安装部222，档位部221抵接于定位部212，档位安装部222设于档位部221其中一侧，且固定于换热主体100，例如，档位部221和档位安装部222一体设置，档位件220呈板状。档位部221具有档位开口2201，或者，档位部221与定位部212共同限定出档位开口2201。
档位安装部222设有探温螺纹孔2202，探温组件200还包括探温螺钉240，探温螺钉240设于探温螺纹孔2202以将档位件220固定于换热主体100，以便 于档位件220的拆装。
其中，探温螺纹孔2202与测温孔121的轴向平行，便于装配，防止温度探头210伸出测温孔121的部分妨碍档位件220的安装。可选地，换热主体100的探测器安装面122开设有探温螺纹孔2202，使安装结构紧凑。
输水流道包括入水段1121和出水段1122，例如，入水段1121和出水段1122的流通方向平行或相反，换热主体100具有一一对应入水段1121和出水段1122的两个测温孔121，测温孔121的轴向与对应的入水段1121和出水段1122的流通方向的流通方向平行或呈夹角。
换热装置10包括两组探温组件200，其中一组探温组件200对应其中一个测温孔121设置、另一个探温组件200对应另一个测温孔121设置。例如，两组探温组件200相对设置，具体为，两组探温组件200的档位件220的档位开口2201相对开设；或者，两组探温组件200平行设置，具体为，两组探温组件200的档位件220的档位开口2201朝向同侧开设。
两组探温组件200对应地探测入水段1121和出水段1122处的流体的温度，便于获取流体出入输水流道的温度状态。可选地，换热装置10包括与入水段1121连通的入水接口101、与出水段1122连通的出水接口102，入水接口101和出水接口102凸设于换热主体100同侧，测温孔121朝向背离入水接口101和出水接口102的一侧开设，如此，即可获取流体出入输水流道的温度状态，同时，便于探温组件200的安装，防止入水接口101和出水接口102的存在妨碍探温组件200的安装。
本申请实施例还提供了一种水力模块，本申请实施例的水力模块，可以用于空气能热水器，也可以用于地暖、暖气片等家居采暖设备，在此不再具体限定。需要说明的是，水力模块用于将冷媒流道中的冷媒与输水流道中的水进行换热，从而对水进行加热，或对水进行冷却，从而输出设定温度的水，输送至水箱等储水装置中，或者输送至地暖管、暖气片等放热装置中。
