具体地，加热元件30和导流元件20均设置在流体通道1114内。
请参阅图4至图6，进一步地，导流元件20包括环形部21、多个导流片22、支撑柱23和进水部24。多个导流片22连接环形部21的周缘。多个导流片22沿环形部21的周向排布，每个导流片22沿环形部21的周向呈螺旋状向上延伸。支撑柱23自导流片22沿环形部21的轴向延伸。进水部24自环形部21沿环形部21的轴向延伸。
上述实施方式的导流元件20中，多个导流片22均沿环形部21的周向呈螺旋状延 伸，导流片22可以将流体导向呈螺旋状流动，可以提高流体的流速，进而提高集热泵10的流体传动效率。
请参阅图4和图5，具体地，支撑柱23和进水部24分别位于环形部21的两侧，在本实施方式中，每个导流片22形成有一个支撑柱23。可以理解的是，在其他实施方式中，每个导流片22可以设置多个支撑柱23，支撑柱23具体的数量可以根据不同情况来选择，在此不做限定。
支撑柱23的设置有利于导流元件20的安装与定位，进而限制导流元件20与泵壳11的相对位置，提升导流元件20与泵壳11的稳定性。
其中，支撑柱23与导流片22可以一体成型，如此，可减少所需装配的部件，简化导流元件20的结构。当然，在其他实施方式中，支撑柱23与导流片22也可以分体成型。例如，可通过胶接、卡接、螺丝固定等方式进行连接。具体的连接方式可以根据实际情况来设置，在此不做限定。

在本申请实施方式中，进水部24和进水通道241均为圆柱状，当然，在其他实施方式中，进水部24和进水通道241还可为其他形状，例如矩形状、梯形状等。进水部24和进水通道241的具体形状可以根据实际情况来选择，在此不做限定。
请再次参阅图3，在本实施方式中，上壳111的进水口1112套设进水部24，如此防止流体从上壳111与进水部24之间的间隙流入流体通道1114，有利于集热泵10的正常工作。
请参阅图4和图5，具体地，导流片22包括第一端部221和与第一端部221相对的第二端部222，第一端部221和第二端部222沿环形部21的周向排布，沿环形部21的径向，第一端部221和/或第二端部222与环形部21之间形成有间隙223。
如此设置，能够降低导流片22与环形部21之间的连接面积，以减少流体与导流片22之间的阻力，使得导流片22在给流体导流的时候流体的流动更为顺畅，从而减少水力的流动损失。
更进一步地，第一端部221的高度低于第二端部222的高度。
如此设置，流体从第一端部221经过第二端部222，并从导流片22流出时，流体能够较为容易的形成螺旋状，此时，螺旋状的流体流速更加高，使得流体能够较好的进入 流体通道1114，并与加热元件30接触，从而提升集热泵10的加热效率。
在本申请实施方式中，在沿环形部21的周向排布的相邻两个导流片22中，其中一个导流片22的第二端部222高于另外一个导流片22的第一端部221。
如此设置，在流体沿着导流片22流出时，流体能够较为容易的形成螺旋状，此时，螺旋状的流体流速更加高，使得流体能够较好的进入流体通道1114，并与加热元件30接触，从而提升集热泵10的加热效率。
具体地，导流片22与环形部21可以一体成型，如此，可减少所需装配的部件，简化导流元件20的结构。当然，在其他实施方式中，导流片22与环形部21也可以分体成型，例如，可通过胶接、卡接、螺丝固定等方式进行连接。具体的连接方式可以根据实际情况来设置，在此不做限定。
请参阅图4和图5，进一步地，导流片22包括朝向上的导流面224和连接导流面224的侧面225，沿导流片22的螺旋方向，导流面224的宽度减小。
在本申请实施方式中，流体沿着导流面224的表面流动，沿导流片22的螺旋方向，导流面224宽度减小，使得流体与导流面224之间的接触面积也逐渐减少，如此，可以减小导流面224给流体带来的阻力，降低流体流动的损耗，提升流体的流速，使从导流面224流出的流体能够较好的形成螺旋水流，从而提高集热泵10的流体传动效率。
侧面225的设置能够防止流体在导流面224的表面流动时，从导流面224的周围流出，使得流体能够充分地经过导流面224并从导流片22流出，以使得能够较好的形成螺旋水流，从而提高集热泵10的流体传动效率。
在本实施方式中，导流片22的设置能够使得流体在流体通道1114内形成螺旋状，电机13和叶轮12的设置同样能够使得流体在流体通道1114内形成旋涡状，二者同时工作，能够使得流体通道1114内的流体流速较快，形成的螺旋更为明显，以进一步地提高集热泵10的流体传动效率。
其中，叶轮12的转动方向与导流片22的螺旋方向相同。
进一步地，在本申请实施方式中，沿导流片22的螺旋方向，侧面225的宽度相等。
如此，使得导流片22的形成和制作较为简单，提升了导流片22的量产化，从而提升了导流元件20和集热泵10的量产化。
可以理解的是，在其他实施方式中，沿导流片22的螺旋方向，侧面225的宽度也可以不相同。具体可以根据不同情况来设置侧面225的宽度范围。在此不做限定。
请参阅图3，在某些实施方式中，导流片22靠近叶轮12的一端与叶轮12的底部之间的距离h大于或等于叶轮12厚度g的一半。
如此设置，在叶轮12工作的情况下，叶轮12不会受到导流片22的影响，提升了 叶轮12工作的稳定性。
另外，如此设置，使得叶轮12与导流片22之间存在一定的空间，该空间可用于存储未形成旋涡状的流体，在叶轮12工作的情况下，能够使得该空间存储的流体形成旋涡状，从而提高集热泵10的流体传动效率。
当然，导流片22靠近叶轮12的一端与叶轮12的底部之间的距离h不仅仅可以大于或等于叶轮12厚度g的一半，具体数值可以根据实际情况来选择。在此不做限定。
请参阅图4，在某些实施方式中，导流元件20与上壳111之间设置有导流罩70，导流罩70靠近导流元件20的一侧形成有螺旋面71，如此设置，在流体通道1114内的流体经过螺旋面71时，能够进一步地提升流体的螺旋性能，从而提高集热泵10的流体传动效率。
进一步地，以下对本申请的集热泵的工作方式进行解释说明：
请参阅图2，流体A和流体B从进水口1112进入集热泵10中，然后在导流元件20和叶轮12的作用下，在流体通道1114内形成漩涡，最后从出水口1113流出。
具体地，以下对在流体通道1114内如何形成漩涡进行解释说明：
请参阅图3，流体先从进水口1112进入进水通道214，然后从流体通道214进入导流片22，在导流片22的导流下，流体从导流片22的第二端部222流出，由于第二端部222具有一定的高度，此时，从第二端部222出来的流体较为容易的形成漩涡。
另外，叶轮12工作时，能够进一步地对流体通道1114内的流体进行作用，以使得流体通道1114内的流体充分形成漩涡。
请参阅图7至图10，在某些实施方式中，加热元件30包括固定在连接部32上并凸出连接部32的安装部33，密封元件40位于安装部33和侧壁1116的内侧面之间，安装部33抵压密封元件40。
如此，在加热元件30收容于泵壳11内的情况下，安装部33能够挤压密封元件40，以使得加热部31与安装孔1117之间的密封性更加好，从而防止泵壳11内的流体穿过安装孔1117流向连接部32的情况发生，提升了集热泵10的安全性，有利于集热泵10的正常工作。
在本申请实施方式中，密封元件40包括但不限于O型圈。
请参阅图8和图9，在某些实施方式中，集热泵10包括设置在安装孔1117中的抵靠件50，抵靠件50套设在连接部32上，密封元件40夹设在抵靠件50和安装部33之间。
抵靠件50能够抵持住密封元件40，在抵靠件50抵持密封元件40的情况下，抵靠件50能够支撑密封元件40，以防止密封元件40的定位出现异常的情况，从而提升密封 元件40的稳定性，使得密封元件40的密封效果较好。
另外，抵靠件50设置在安装孔1117中，如此，在连接部32穿设于安装孔1117的情况下，抵靠件50能抵靠连接部32，从而提升安装孔1117的密封性，进而使得集热泵10的密封效果较好。
请参阅图8和图9，在某些实施方式中，集热泵10包括与抵靠件50及连接部32连接的紧固组件60，紧固组件60将加热元件30紧固在泵壳11上，并使抵靠件50抵靠密封元件40。
如此设置，一来能够将加热元件30紧固在泵壳11上，提升加热元件30的稳定性，二来能够挤压抵靠件50以使抵靠件50抵靠密封元件40，使得抵靠件50与密封元件40之间连接更加紧密，提升集热泵10的密封性能，有利于集热泵10的正常使用。
请参阅图8和图9，在某些实施方式中，紧固组件60包括紧固件61、压盖62和锁紧件63。紧固件61与安装部33固定连接，紧固件61穿设于密封元件40和抵靠件50。压盖62抵靠在泵壳11的外表面，压盖62套设在紧固件61上并抵压抵靠件50。锁紧件63位于压盖62背离紧固件61一侧，锁紧件63连接紧固件61并锁紧压盖62。
如此设置，锁紧件63与紧固件61配合，能够将加热元件30紧固在泵壳11上，结构简单，易于实现。并且，锁紧件63与紧固件61配合还能够固定压盖62，以使得压盖62与能够紧紧贴合在泵壳11的外表面，在压盖62与泵壳11贴合时，压盖62能够挤压抵靠件50，以使得抵靠件50与密封元件40连接更加紧密，从而提升集热泵10的密封效果。
在本申请实施方式中，紧固件61靠近压盖62的一侧设置有螺纹，锁紧件63为螺帽，锁紧件63与压盖62通过螺纹连接实现固定。当然，在其他实施方式中，紧固件61与锁紧件63还可以采用固定插销、扣合等方式连接。具体可以根据实际情况来设置，在此不做限定。
进一步地，密封元件40、压盖62和抵靠件50上设置有穿孔，紧固件61通过穿孔露出于压盖62。
具体地，紧固件61与穿孔活动密封，如此，在集热泵10工作的情况下，泵壳11内的流体不能够穿过穿孔并落出至泵壳11外，从而防止流体附着在连接部32上导致连接部32出现损坏，有利于提升集热泵10的正常使用。
更进一步地，穿孔周缘可设置有O型圈，通过O型圈来实现活动密封的效果，结构简单，易于实现。可以理解的是，在其他实施方式中，活动密封可采用其他结构来实现。具体可以根据不同情况来进行设置。在此不做限定。
具体地，加热部31包括但不限于加热管式加热器、涂层电阻式加热器等。具体类 型可以根据实际情况来选择。在此不做限定。
更进一步地，紧固件61与安装部33可以一体成型，如此，可减少所需装配的部件，简化加热元件30的结构。当然，在其他实施方式中，紧固件61与安装部33也可以分体成型。例如，可通过胶接、卡接、螺丝固定等方式进行连接。具体的连接方式可以根据实际情况来设置，在此不做限定。
请参阅图7至图9，在某些实施方式中，连接部32呈直线的管状。
如此设置，能够减小连接部32的尺寸，降低了连接部32的生产材料的用量，也即是说，降低了连接部32的制造成本，有利于集热泵10的量产化。另外，在本申请实施方式中，连接部32用于与外部供电设备进行连接，外部供电设备通过连接部32给加热部31进行供电，在连接部32呈直线的管状的情况下，有利于提升连接部32的导电性能，从而他提升集热泵10的工作效率。
具体地，电阻定律为R＝ρL/S，其中ρ：制成电阻的材料的电阻率；L：绕制成电阻的导线长度；S：绕制成电阻的导线横截面积；R：电阻值。由于在材料相同时，材料的电阻率不变，此时，电阻值R与材料的长度L呈正比。因此，将连接部32制作成直线的管状能够在相同的尺寸空间内降低连接部32的长度，从而减小连接部32的电阻，有利于提升连接部32的导电性能，从而他提升集热泵10的工作效率。
当然，连接部32不仅仅可以为呈直线的管状。在其他实施方式中，连接部32也可以为其他形状，具体可以根据实际情况来设计，在此不做限定。
请参阅图10，在某些实施方式中，安装孔1117为连续的通孔。在本申请实施方式中，安装孔1117为跑道型。如此设置，在加热元件30安装的过程中，能够防止连接部32和紧固件61与泵壳11接触，导致连接部32和紧固件61出现损坏，使得加热元件30的安装更加方便、快捷。
可以理解的是，在其他实施方式中，安装孔1117也可以为其他形状。具体可以根据不同情况来设置，在此不对安装孔1117的具体形状做限定。
进一步地，安装孔1117的尺寸小于密封元件40的尺寸，如此，防止密封元件40从安装孔1117脱离，有利于提升密封元件40的稳定性。
请参阅图11，本申请实施方式提供的一种集热泵10的组装方法，组装方法包括：
S01：提供一泵壳11，泵壳11包括顶壁1115和连接顶壁1115的侧壁1116，侧壁1116开设有安装孔1117；

本申请实施方式的集热泵10的组装方法中，密封元件40抵靠在侧壁1116的内表面并密封加热部31和安装孔1117之间的空间，这样可以有效地防止泵壳11内的流体从安装孔1117漏出，结构简单。另外，加热元件30的连接部32从泵壳11的侧面伸出，使得加热元件30可以充分利用泵壳11的横向尺寸，有利于加热元件30与泵壳11配合更加紧凑。
在步骤S04中，将连接部32从泵壳11内经过安装孔1117伸出至泵壳11外，指的是，将加热元件30倾斜伸入泵壳11内，然后使连接部32从安装孔1117伸出。
在某些实施方式中，组装方法包括：
提供抵靠件50，将抵靠件50套设在连接部32上以使抵靠件50抵压密封元件40。
如此，提升了集热泵10的密封性能。
请参阅图12，在某些实施方式中，组装方法包括：
S05：提供压盖62和锁紧件63；
S06：将压盖62套设在与连接部32固定连接的紧固件61上，紧固件61穿设于密封元件40和抵靠件50；
S07：将锁紧件63与紧固件61连接，以使压盖62抵靠在泵壳11的外表面，从而防止密封元件40和加热元件30松动。
如此，提升了集热泵10的密封性能。
