Fig. 1 and 2 are schematic structural views of a water side thermal management integrated module in the prior art. Referring to fig. 1 and 2, the present thermal management integrated module is mainly divided into a refrigerant side integrated module, a water side integrated module and a coupling of the two. The water side heat management integrated module mainly comprises water valves, water pumps, water loop flow channel plates 12, plate heat exchangers and other parts. Wherein water valves, water pumps, plate heat exchangers and other parts are assembled on the water circuit flow channel plate 12. The water circuit flow channel plate 12 is provided with a pipe joint at the outer part and a water channel at the inner part for cooling liquid to flow.

The water pump used by the integrated module is different from the traditional water pump in that the water inlet pipe and the water outlet pipe (the traditional water pump uses a hose to be connected with the water inlet pipe and the water outlet pipe) are omitted, and the water pump head 11 and the water loop runner plate 12 are matched to form corresponding water inlet and outlet channels.

Specifically, as shown in fig. 1 and 2, the pump head of the integrated water pump has a separate water inlet pipe orifice 13 and water outlet pipe orifice 14, and the water circuit flow path plate 12 has a water inlet pipe 15 and a water outlet pipe 16. The water inlet pipe orifice 13 is connected with the water inlet pipe 15 by a sealing ring so as to form a water inlet channel in a matching way; the outlet nozzle 14 and outlet conduit 16 need to be sealingly connected to cooperate to form an outlet passage.

The pump head 11 is inserted into the flow channel plate, is sealed with the water circuit flow channel plate 12 by a sealing ring, and is fastened and connected by using screws. Specifically, the water inlet and outlet channels of the water pump are formed by the pump head and the water loop runner plate 12 in a matched manner, the pump head 11 of the water pump is required to be inserted into the runner plate, and the inner leakage and the outer leakage are sealed through the two sealing rings. The scheme mainly has the following defects:

(1) sealing rings are needed to seal the water inlet pipe orifice 13, the water inlet pipe orifice 15, the water outlet pipe orifice 14 and the water outlet pipe orifice 16, and the water pump head 11 and the water loop flow channel plate 12, so that the material waste caused by the functional overlapping exists, and the cost is high;

(2) the middle shell of the water pump is connected with the pump head of the water pump by adopting bolts, the pump head 11 of the water pump is connected with the runner plate by adopting bolts, and the number of the bolts is large, so that certain cost is wasted;

(3) the potential risk of leakage at the sealing part is increased due to the problems of damage, aging and the like of the sealing ring;

(4) before the water pump is assembled with the water circuit flow channel plate 12, two sealing rings are required to be arranged on the upper shell of the water pump, and the process is complex.

In order to improve the above technical problems, a water pump flow passage plate integrated structure and a thermal management integrated module are provided in the following embodiments.

Referring to fig. 3, 4, 5 and 6, the present embodiment provides a water pump runner plate integrated structure 20, which includes a water pump unit 100 and a runner plate 200.

The water pump unit 100 includes a housing 110, an impeller (not shown) and a driving machine, the driving machine is disposed in the housing 110, and the impeller is in driving connection with the driving machine;

the flow channel plate 200 is provided with a containing groove 201, and a water inlet flow channel 202 and a water outlet flow channel 203 are arranged in the containing groove 201; the water pump unit 100 is in sealing connection with the accommodating groove 201, and the impeller is positioned in the accommodating groove 201;

the water pump unit 100 is configured to drive the impeller to rotate so that the water flow entering the accommodating recess 201 from the water inlet flow passage 202 is discharged from the water outlet flow passage 203 after being pressurized.

The water pump runner plate integrated structure 20 of this embodiment directly connects the housing 110 with the runner plate 200, and the impeller is directly placed in the accommodating groove 201 of the runner plate 200. Namely, by eliminating the pump head of the integrated water pump in the prior art, the shell 110 and the runner plate 200 are combined together to form a working chamber of the water pump, so that the structures of the water pump and the runner plate 200 are simplified; meanwhile, the mode of the pump head is omitted, the sealing between the pump head and the runner plate 200 and the screw connecting piece 700 between the pump head and the shell 110 in the prior art are reduced, the material waste is reduced, the assembly process is simplified, the cost is obviously optimized, and in addition, the leakage risk is greatly reduced because two sealing structures (the sealing rings between the water inlet pipe orifice 13 and the water inlet pipe 15 and between the water outlet pipe orifice 14 and the water outlet pipe 16) are reduced.

Further, the accommodating groove 201 of the flow channel plate 200 is provided with a water inlet flow channel 202 and a water outlet flow channel 203, and the water inlet flow channel 202/the water outlet flow channel 203 are matched with the impeller to realize the operation of discharging the pressurized water flow so as to ensure the fluid conveying function of the water pump. In summary, the integrated structure 20 of the water pump runner plate has the advantages of simple structure, convenient assembly and disassembly, good sealing effect, low leakage risk, less material consumption and lower cost, and therefore, the economic benefit is remarkable.

With continued reference to fig. 3-6, additional structural details of the water pump flow field plate integrated structure 20 are illustrated.

As can be seen from the figure, in this embodiment, the flow channel plate 200 has a supporting boss thereon, and the top surface of the supporting boss is the surface connected to the housing 110 of the water pump unit 100. The support boss is a cylinder. The receiving groove 201 is a cylindrical groove provided in the support boss, and the receiving groove 201 is arranged concentrically with the support boss.

It is understood that in other embodiments of the present utility model, the water pump unit 100 may not be sealed with the top surface of the support boss (i.e., the top of the receiving recess 201), but be sealed with the inner wall of the receiving recess 201, etc., as long as the water pump unit 100 is sealed with the receiving recess 201; further, the receiving groove 201 may be sealed not with the housing 110 of the water pump unit 100 but with other portions of the water pump unit 100, which is only an example and not limited thereto.

In the present embodiment, the water inlet flow channel 202 and the water outlet flow channel 203 extend in different directions, respectively. Further, the water inlet flow passage 202 extends in the axial direction of the accommodating groove 201. This ensures that the water flow can enter the accommodating groove 201 as soon as possible in the shortest path and complete the pressurized output action of the water flow in cooperation with the impeller, thereby improving the operation efficiency of the water pump unit 100.

Alternatively, the water inlet flow channel 202 is perpendicular to the bottom of the accommodating recess 201. Specifically, the water inlet flow passage 202 is penetratingly provided at the center of the bottom wall of the accommodating recess 201. Specifically, the water inlet channel 202 is a cylindrical hole, and the central axis of the water inlet channel 202 is arranged in line with the central axis of the accommodating groove 201. This arrangement ensures stability and reliability of the water pump unit 100 when carried.

As can also be seen, the water pump flow field plate integrated structure 20 further includes a support block 310 and a plurality of connecting ribs 320; the support block 310 is positioned at the center of the water inlet flow channel 202; and a plurality of connection ribs 320 are provided at the circumferential side of the support block 310 such that the support block 310 is connected with the inner wall of the water inlet flow passage 202 through the connection ribs 320.

Specifically, in the present embodiment of the present utility model, the support block 310 is connected to the water inlet flow channel 202 by three connection ribs. The supporting block 310 is a cylinder, and three connecting ribs are circumferentially and uniformly distributed on the peripheral wall of the supporting block 310. And the central axis of the support block 310 remains collinear with the central axis of the water inlet flow passage 202.

That is, the circumferential side of the support block 310 and the inner circumferential wall of the water inlet flow channel 202 form an annular water inlet divided into a plurality of segments by the connection rib. Such an arrangement can enable the impeller and other components of the water pump unit 100 to be abutted against the support block 310, and ensure the smoothness of water inlet of the water inlet channel 202.

As can be seen from the figure, the support block 310 is provided at the center thereof with a support recess 311, and the bottom of the support recess 311 is spaced apart from the bottom surface of the support block 310 by a predetermined distance. I.e., the support recess 311 is a blind counterbore. Optionally, the support recess 311 is a cylindrical counterbore. The support recess 311 can cooperate with the water pump unit 100 to ensure accuracy in the operational assembly and operation of the water pump unit 100.

Referring to fig. 3 to 5, it can be seen that the groove bottom of the accommodating groove 201 is provided with a circular ring protrusion 210; the circular ring protrusion 210 is disposed around the circumference of the water inlet channel 202, and the center of the water inlet channel 202 is concentric with the center of the circular ring protrusion 210. The circular ring protrusion 210 has a cylindrical annular structure, and the circular ring protrusion 210 can limit the inflow direction; meanwhile, the part of the circular ring protrusion 210 and the part of the inner wall of the accommodating groove 201 can be enclosed to form the water outlet channel 203. Further, the water pump flow field plate integrated structure 20 further includes a first bottom step ring 410 and a second bottom step ring 420 that are concentrically arranged; the first bottom step ring 410 is concentrically arranged within the annular projection 210, and the first bottom step ring 410 is located below the bottom of the annular projection 210 in the axial direction; the second bottom step ring 420 is located at an inner peripheral wall of the first bottom step ring 410, and the second bottom step ring 420 is located below the bottom of the first bottom step ring 410 in the axial direction; the inner peripheral wall of the second bottom step ring 420 encloses an opening forming the water inlet flow channel 202.

Specifically, the first bottom step ring 410 is cylindrical, the first bottom step ring 410 is arranged concentrically with the annular protrusion 210, and the height of the first bottom step ring 410 is smaller than the height of the annular protrusion 210. Further, an annular surface is formed between the first bottom step ring 410 and the annular protrusion 210, and is inclined obliquely downward toward the water inlet flow channel 202. I.e., the top of the first bottom step ring 410 is lower than the bottom of the annular protrusion 210.

The first bottom step ring 410 and the second bottom step ring 420 cooperate to form a stepped water inlet mode, so that the water inlet of the water inlet channel 202 is stable, and the influence of turbulence on the water pump operation is avoided.

In the present embodiment, the caliber of the water inlet flow channel 202 tends to decrease along the direction from the second bottom step ring 420 to the bottom of the water inlet flow channel 202. Specifically, the side of the water inlet channel 202 near the second bottom step ring 420 is a flare with a straight inner wall, and the end of the flare far from the second bottom step ring 420 is connected through a cylindrical opening.

Further, the shape of the water outlet channel 203 is a spiral gradually deforming shape. The spiral gradually deforms to ensure smooth water discharge, and turbulence and the like in the water discharge process can be avoided by increasing the travel of the water discharge flow channel 203.

In the present embodiment, the water outlet flow passage 203 is provided in the circumferential direction of the accommodation groove 201. Alternatively, the water outlet flow channel 203 penetrates through the inner wall of the accommodating recess 201 to form a through-penetration 204, and the through-penetration 204 is located below the top surface of the accommodating recess 201.

As can also be seen from fig. 3 to 5, in the present embodiment of the utility model, the water pump flow field plate integrated structure 20 further includes a first top step ring 510 and a second top step ring 520 that are concentrically arranged;

the first top step ring 510 is concentrically arranged outside the annular protrusion 210; the bottom of the first top step ring 510 and the bottom of the circular ring protrusion 210 are located on the same plane along the axis direction, and the top of the first top step ring 510 is located above the top of the circular ring protrusion 210;

the second top step ring 520 is located at the outer circumference of the first top step ring 510, and the bottom of the second top step ring 520 is located at the top surface of the first top step ring 510 in the axial direction, and the top of the second top step ring 520 is located below the top surface of the accommodation groove 201;

the water outlet flow passage 203 penetrates through the inner wall of the receiving groove 201 to form a through-opening 204, and the through-opening 204 is located under the first top step ring 510.

The second top step ring 520 can be engaged with the engagement protrusion 111 of the bottom of the housing 110 to form an engagement, thereby securing a sealing effect when the housing 110 is connected with the flow field plate 200. And the first top step ring 510 can define the height of the outlet channel 203.

In the present embodiment, the water outlet flow channel 203 extends in an arc shape, and the water outlet flow channel 203 extends along the inner wall of the accommodating groove 201. Specifically, as can be seen from the figure, the annular protrusion 210 encloses with the inner wall of the accommodating recess 201 to form the water outlet channel 203. And a position of a minor arc (a circumferential angle smaller than 180 °) ending at the through-penetration 204 has a first transition point in the circumferential direction of the accommodation groove 201. From the first transition point to the through-opening 204, the water outlet channel 203 is recessed toward the bottom wall of the accommodating recess 201 to form a continuous arc-shaped bottom groove 205; and the water outlet flow path 203 is recessed toward the side wall of the accommodating recess 201 to form a continuous arc-shaped side groove 206.

Further, in the present embodiment of the present utility model, the water pump runner plate integrated structure 20 further includes a drainage plate 600; the drainage plate 600 is disposed at the bottom of the receiving groove 201; along the axial direction, the top of the drainage plate 600 extends to be flush with the first top step ring 510; and the radial inner side of the drainage plate 600 is connected with the periphery of the circular ring protrusion 210, and the radial outer side of the drainage plate 600 and the inner side wall of the accommodating groove 201 enclose to form part of the water outlet flow channel 203.

Optionally, the drainage plate 600 is a circular arc plate facing the water inlet channel 202 in a circular shape. The drainage plate 600 can smoothly shunt inflow and outflow water to ensure smooth operation of the water pump unit 100.

As can be seen from the figure, the water inlet channel 202 is opposite to the axis of the impeller, and the water outlet channel 203 is opposite to the periphery of the impeller. In this way, the water inlet channel 202 and the water outlet channel 203 are kept relatively vertical, so that the water pump unit 100 can be ensured to be capable of water inlet and water outlet in the shortest path, and the working efficiency of the water pump unit 100 is improved. Referring to fig. 3 to 6, it can be seen that the top of the accommodating recess 201 has a mounting surface 220, the bottom of the housing 110 has a mating surface 120, and the mounting surface 220 can abut against the mating surface 120;

the mounting surface 220 has a plurality of first clamping portions 230 circumferentially arranged thereon, and the mating surface 120 has a plurality of second clamping portions 130 circumferentially arranged thereon; the first clamping portions 230 and the second clamping portions 130 are the same in number and correspond to each other to achieve mutual clamping fit.

Optionally, the mounting surface 220 and the mating surface 120 are both annular surfaces. The first clamping portion 230 is a protrusion extending in the radial direction, and the second clamping portion 130 is a groove extending in the radial direction. The first and second engaging portions 230 and 130 are opposite in shape, and the first and second engaging portions 230 and 130 can be engaged with each other. The first clamping portion 230 and the second clamping portion 130 cooperate to ensure stable sealing connection between the housing 110 and the flow channel plate 200, and limit and position the housing 110 and the flow channel plate 200 in the circumferential direction.

Further, as can be seen from the figure, the water pump runner plate integrated structure 20 further includes a connecting piece 700, and a first connecting portion 240 disposed on the first clamping portion 230; and a second connecting portion 140 disposed on the housing 110, the second connecting portion 140 facing the second clamping portion 130; the connection member 700 connects the first connection part 240 and the second connection part 140, respectively, to achieve a tight connection of the housing 110 and the flow field plate 200.

Specifically, the first connection part 240 includes two through holes provided on the first clamping part 230. The second clamping portion 130 is disposed on the housing 110, and two through holes are also disposed on the second clamping portion 130. The two through holes of the first connection part 240 are in one-to-one correspondence with the two through holes of the second connection part 140. The connection member 700 is a screw, and the screw sequentially penetrates through holes of the first connection part 240 and the second connection part 140 to realize stable connection of the housing 110 and the flow channel plate 200.
