Referring to fig. 4 and 5, the pod 30 further includes an inner side 31, an outer side 32, a first end side 33, a second end side 34 opposite to the first end side 33, and a bottom surface 35. The pod 30 extends about a central axis K, the inner side 31 is helical about the central axis K, and the pod 30 has an opening 36 through the inner side 31 and the outer side 32. The flow guide bottom surface 35 connects the inner side surface 31 and the outer side surface 32.

Referring to fig. 4 and 5, in the embodiment of the present invention, the height of the inner side surface 31 gradually changes along the circumferential direction of the central axis K.

Since the fluid flows in the inner side surface 31, the height of the inner side surface 31 is gradually changed, that is, the area of the inner side surface 31 is changed, so that the fluid can better flow out from the outlet, and the fluid flow efficiency of the heat collection pump is improved.

Specifically, in the extending direction of the inner side surface 31 on the side away from the opening 36 toward the side of the opening 36, the height of the inner side surface 31 becomes gradually larger; the height of the inner surface 31 is gradually reduced in the extending direction of the inner surface 31 on the side of the opening 36 toward the side away from the opening 36.

Since the height of the first end side 33 is greater than the height of the second end side 34, in the case where the opening 36 is provided at the first end side 33, the size of the opening 36 can be made larger, thus facilitating the outflow of the fluid from the opening 36.

Wherein, the edge 40 of the opening 36 on the inner side surface 31 is rounded.

Since the fluid will flow out from the opening 36, the edge 40 of the opening 36 is rounded to reduce the resistance of the opening 36 to the fluid, thereby facilitating the fluid to flow out from the opening 36, reducing the fluid loss at the opening 36, and improving the fluid flow efficiency of the heat collecting pump.

It will be appreciated that the deflector 37 and the opening 36 may be integrally formed, thereby reducing the number of parts required to be assembled and simplifying the construction of the pod 30. Of course, in other embodiments, the flow guide portion 37 and the opening 36 may be formed separately. For example, the connection can be made by gluing, clipping, screwing, etc. The specific connection mode may be set according to actual situations, and is not limited herein.

The surface of the flow guide part 37 is smoothly arranged, so that the resistance of the fluid flowing on the surface of the flow guide part 37 is reduced, the flow velocity of the fluid is improved, and the flow of the fluid is facilitated.

The arrangement of the opening 39 makes the air guide sleeve 30 in an unclosed annular shape, so that the air guide sleeve 30 is convenient to mount and dismount, and the structure is simple and easy to realize.

Referring to fig. 4, 8 and 9, further, the flow guiding element 20 includes an annular portion 21, a plurality of flow guiding plates 22, a supporting column 23 and a water inlet portion 24. A plurality of guide vanes 22 connect the periphery of the annular portion 21. The plurality of guide vanes 22 are arranged along the circumferential direction of the annular portion 21, and each guide vane 22 extends spirally upward along the circumferential direction of the annular portion 21. The support column 23 extends from the guide piece 22 in the axial direction of the annular portion 21. The water inlet portion 24 extends from the annular portion 21 in the axial direction of the annular portion 21.

In the flow guiding element 20 of the above embodiment, the plurality of flow guiding plates 22 each extend spirally along the circumferential direction of the annular portion 21, and the flow guiding plates 22 can guide the fluid to flow spirally, so that the flow rate of the fluid can be increased, and the fluid transmission efficiency of the heat collecting pump 10 can be improved.

Referring to fig. 4 and 8, specifically, the supporting columns 23 and the water inlet portion 24 are respectively located at two sides of the annular portion 21, and in the present embodiment, each of the guide vanes 22 is formed with one supporting column 23. It is understood that in other embodiments, a plurality of support columns 23 may be provided for each guide vane 22, and the specific number of support columns 23 may be selected according to different situations, which is not limited herein.

The supporting columns 23 are arranged to facilitate the installation and positioning of the flow guiding element 20, so as to limit the relative position of the flow guiding element 20 and the housing 11, and improve the stability of the flow guiding element 20 and the housing 11.

The flow guiding portion and the opening can be integrally formed, so that the number of parts to be assembled can be reduced, and the structure of the flow guiding element 20 can be simplified. Of course, in other embodiments, the flow guide portion and the opening may be formed separately. For example, the connection can be made by gluing, clipping, screwing, etc. The specific connection mode may be set according to actual situations, and is not limited herein.

The embodiment of the present invention provides that the supporting column 23 can be rectangular, and in other embodiments, the supporting column 23 can also be in other shapes, and the specific shape of the supporting column 23 can be specifically set according to different situations, which is not limited herein.

Referring to fig. 8 and 9, further, the water inlet portion 24 is formed with a water inlet channel 241, and the fluid can enter the flow guiding element 20 through the water inlet channel 241 and then be guided out through the flow guiding plate 22, so that the fluid can flow spirally, and the flow rate of the fluid is increased, thereby increasing the fluid transmission efficiency of the heat collecting pump 10.

The embodiment of the present invention provides that the water inlet portion 24 and the water inlet channel 241 are both cylindrical, and of course, in other embodiments, the water inlet portion 24 and the water inlet channel 241 can also be in other shapes, such as rectangular shape, trapezoidal shape, etc. The specific shapes of the water inlet portion 24 and the water inlet channel 241 can be selected according to actual conditions, and are not limited herein.

Referring to fig. 3 again, in the present embodiment, the water inlet 1112 of the upper shell 111 is sleeved on the water inlet portion 24, so as to prevent the fluid from flowing into the fluid channel 1114 from the gap between the upper shell 111 and the water inlet portion 24, which is beneficial to the normal operation of the heat collecting pump 10.

Referring to fig. 8 and 9, specifically, the guide vane 22 includes a first end 221 and a second end 222 opposite to the first end 221, the first end 221 and the second end 222 are arranged along a circumferential direction of the annular portion 21, and a gap 223 is formed between the first end 221 and/or the second end 222 and the annular portion 21 along a radial direction of the annular portion 21.

With such an arrangement, the connection area between the guide vane 22 and the annular portion 21 can be reduced to reduce the resistance between the fluid and the guide vane 22, so that the fluid flows more smoothly when the guide vane 22 guides the fluid, thereby reducing the flow loss of the hydraulic power.

Further, the first end 221 has a height lower than that of the second end 222.

With such an arrangement, when the fluid passes through the second end portion 222 from the first end portion 221 and flows out of the baffle 22, the fluid can easily form a spiral shape, and at this time, the spiral fluid flow rate is higher, so that the fluid can better enter the fluid passage 1114 and contact the heating element 1115, thereby improving the heating efficiency of the heat collection pump 10.

In the embodiment of the present invention, in two adjacent guide vanes 22 arranged along the circumferential direction of the annular portion 21, the second end 222 of one guide vane 22 is higher than the first end 221 of the other guide vane 22.

With this configuration, when the fluid flows out along the flow deflector 22, the fluid can easily form a spiral shape, and at this time, the spiral fluid flow rate is higher, so that the fluid can better enter the fluid passage 1114 and contact the heating element 1115, thereby improving the heating efficiency of the heat collection pump 10.

In particular, the deflector 22 and the annular portion 21 may be integrally formed, so that the number of parts required to be assembled is reduced, and the structure of the deflector element 20 is simplified. Of course, in other embodiments, the deflector 22 and the annular portion 21 may be formed separately, and may be connected by gluing, clamping, screwing, or the like. The specific connection mode may be set according to actual situations, and is not limited herein.

Referring to fig. 4 and 8, further, the guide vane 22 includes an upward-facing guide surface 224 and a side surface 225 connecting the guide surface 224, and the width of the guide surface 224 decreases along the spiral direction of the guide vane 22.

The side surface 225 is configured to prevent the fluid from flowing out from the periphery of the baffle surface 224 when flowing on the surface of the baffle surface 224, so that the fluid can sufficiently pass through the baffle surface 224 and flow out from the baffle 22, so that the spiral fluid can be formed well, thereby improving the fluid transmission efficiency of the heat collecting pump 10.

In the present embodiment, the baffle 22 is disposed to enable the fluid to form a spiral shape in the fluid passage 1114, and the motor 13 and the impeller 12 are also disposed to enable the fluid to form a spiral shape in the fluid passage 1114, and both of them work simultaneously, so that the flow rate of the fluid in the fluid passage 1114 is faster, and the formed spiral is more obvious, so as to further improve the fluid transmission efficiency of the heat collecting pump 10.

Wherein, the rotation direction of the impeller 12 is the same as the spiral direction of the guide vane 22.
