Referring now to fig. 1-5, a thermal management system 200 of a vehicle in accordance with an embodiment of the present utility model is described.

As shown in fig. 1, a thermal management system 200 of a vehicle according to an embodiment of the present utility model includes: mount 90 and electronic water pump 100.

Specifically, as shown in fig. 3, the mounting seat 90 has a mounting cavity 91, a first liquid inlet 901 and a first liquid outlet 902 which are communicated with the mounting cavity 91, the electronic water pump 100 is mounted on the mounting seat 90 and comprises a pump shell 70, the pump shell 70 is arranged in the mounting cavity 91, the pump shell 70 is provided with a pump cavity 701, a second liquid inlet 73 and a second liquid outlet 74 which are communicated with the pump cavity 701, the second liquid inlet 73 is communicated with the first liquid inlet 901, the second liquid outlet 74 is communicated with the first liquid outlet 902, the first sealing member 71 extends along the circumferential direction of the pump shell 70 and seals a gap between the mounting seat 90 and the pump shell 70, and the second sealing member 72 extends along the circumferential direction of the pump shell 70 and seals a gap between the mounting seat 90 and the pump shell 70; in the axial direction of the electronic water pump 100, the second liquid inlet 73 is located at a side of the first seal member 71 away from the second seal member 72, and the second liquid outlet 74 is located between the first seal member 71 and the second seal member 72.

It should be noted that, the thermal management system 200 of the vehicle is an important component for adjusting the cabin environment (temperature, humidity, etc.) and other component working environments, wherein the thermal management system 200 of the vehicle mainly includes: valves, heat exchangers, compressors, and pumps, such as the electronic water pump 100 or other water pumps, wherein the thermal management system 200 has a circulating refrigerant, which may be a liquid coolant or a carbon dioxide refrigerant, etc.

The tightness of the electronic water pump 100 may affect the tightness of the entire thermal management system 200, so in the present utility model, the first seal 71 and the second seal 72 are disposed in the gap between the pump housing 70 and the mounting seat 90 of the electronic water pump 100 to perform secondary sealing on the electronic water pump 100, thereby enhancing the tightness of the electronic water pump 100 and the mounting seat 90, avoiding the problem of refrigerant leakage, and further improving the tightness of the thermal management system 200.

Thus, the first seal 71 can perform a sealing function on a side of the second liquid inlet 73 close to the second liquid outlet 74, and the second seal 72 can perform a sealing function on a side of the second liquid inlet 73 away from the first seal 71, so that a secondary seal can be performed between the radially outer side of the pump casing 70 and the mounting seat 90 through the first seal 71 and the second seal 72 to enhance the sealing effect of the thermal management system 200.

For example, the electronic water pump 100 is mounted on the mounting base 90 to integrate the electronic water pump 100 into the thermal management system 200, and the fixing manner of the mounting base 90 and the pump housing 70 may be a bolt connection, a clamping connection, a plugging connection, a plastic riveting connection, or the like, which is not limited herein.

The mounting seat 90 has a mounting cavity 91 formed therein to facilitate mounting the pump housing 70 in the mounting cavity 91 such that the first fluid inlet 901 of the mounting seat 90 communicates with the second fluid inlet 73 of the pump housing 70 and the first fluid outlet 902 of the mounting seat 90 communicates with the second fluid outlet 74 of the pump housing 70.

Preferably, the mounting seat 90 is designed to be in shape with the pump housing 70 of the electronic water pump 100, so that the first liquid inlet 901 of the mounting seat 90 is opposite to the second liquid inlet 73 of the pump housing 70, and the first liquid outlet 902 of the mounting seat 90 is opposite to the second liquid outlet 74 of the pump housing 70, thus, no additional connecting pipelines are required between the first liquid inlet 901 and the second liquid inlet 73 and between the first liquid outlet 902 and the second liquid outlet 74, thereby saving cost, and integrating the electronic water pump 100 onto the mounting seat 90 to realize miniaturized design thereof.

Further, as shown in fig. 3, the first seal 71 and the second seal 72 are installed at the gap between the pump housing 70 and the mount 90, so that a secondary sealing effect can be achieved between the pump housing 70 and the mount 90 to enhance the connection sealability of the pump housing 70 and the mount 90.

As shown in fig. 2 and 3, the second liquid inlet 73 is located on a side, far away from the second seal 72, of the first seal 71, so that the first seal 71 can perform a sealing function on a side, close to the second liquid outlet 74, of the second liquid inlet 73, and the second liquid outlet 74 is located between the first seal 71 and the second seal 72, so that the second seal 72 can perform a sealing function on a side, far away from the first seal 71, of the second liquid inlet 73.

Thus, the second seal between the pump casing 70 and the mount 90 can be achieved by the first seal 71 and the second seal 72 to enhance the seal reliability between the pump casing 70 and the mount 90, reducing the possibility of leakage.

It should be noted that at least one of the first seal 71 and the second seal 72 may be configured as an annular rubber member, so that the sealing effect can be better enhanced by the forced deformation of the rubber member, and the first seal 71 and the second seal 72 may be separate molded members to facilitate separate processing, or at least one of the first seal 71 and the second seal 72 may be integrated on the inner wall of the pump housing 70 and/or the mounting cavity 91, so that the number of assembly steps is reduced to facilitate the improvement of the production efficiency.

According to the thermal management system 200 of the vehicle according to some embodiments of the present utility model, the second liquid inlet 73 is located at a side of the first seal 71 away from the second seal 72, so that the first seal 71 can perform a sealing function at a side of the second liquid inlet 73 close to the second liquid outlet 74, and the second liquid outlet 74 is located between the first seal 71 and the second seal 72, so that the second seal 72 can perform a sealing function at a side of the second liquid inlet 73 away from the first seal 71, and thus, a secondary sealing function between the pump housing 70 and the mounting seat 90 can be performed by the first seal 71 and the second seal 72, so as to enhance the sealing effect of the thermal management system 200.

In some embodiments, as shown in FIG. 3, the inner circumferential surface of the mounting cavity 91 includes a first annular sealing surface 911 and the outer circumferential surface of the pump casing 70 includes a second annular sealing surface 75, the first annular sealing surface 911 surrounding the second annular sealing surface 75, and the first seal 71 disposed between the first annular sealing surface 911 and the second annular sealing surface 75.

That is, the first annular sealing surface 911 is circumferentially disposed radially outwardly of the second annular sealing surface 75, and thus, the first seal 71 is disposed between the first annular sealing surface 911 and the second annular sealing surface 75, so that the first seal 71 can be restrained by the second annular sealing surface 75 radially outwardly of the electronic water pump 100, and the structural stability of the first seal 71 can be enhanced, so that the first seal 71 can seal between the radially outwardly of the electronic water pump 100 and the mount 90.

At the same time, the first annular sealing surface 911 surrounds the second annular sealing surface 75, enabling the first seal 71 to effect a seal between the pump housing 70 and the mount 90 in the radial direction of the electronic water pump 100.

Further, as shown in FIG. 3, the inner diameter of the first annular sealing surface 911 is W1, the outer diameter of the second annular sealing surface 75 is W2, and the width of the first seal 71 perpendicular to the axial direction of the electronic water pump 100 is W3, 0.1.ltoreq.W3- (W1-W2))/W3.ltoreq.0.35.

For example: (w3- (W1-W2))/w3=0.15, or (w3- (W1-W2))/w3=0.23, or (W3- (W1-W2))/w3=0.35, that is, when the inner diameter of the first annular sealing surface 911, the outer diameter of the second annular sealing surface 75, and the width of the first seal 71 perpendicular to the axial direction of the electronic water pump 100 satisfy the above-described value ranges, it is possible to ensure that the first seal 71 has a sufficient sealing effect.

Of course, the above values are merely examples, and are not meant to be limiting.

Further, as shown in fig. 3, the outer peripheral surface of the pump casing 70 includes a first tapered surface 76 connected to the second annular sealing surface 75, the first tapered surface 76 being connected to an end surface of one axial end of the pump casing 70, the outer diameter of the first tapered surface 76 increasing in a direction approaching the second annular sealing surface 75.

That is, the outer diameter of the first tapered surface 76 decreases in a direction away from the second annular sealing surface 75, so that the outer diameter of the upper end of the first tapered surface 76 is smaller, which can reduce the difficulty in mounting the first seal 71 when the first seal 71 is mounted.

Therefore, by arranging the first conical surface 76, the first sealing element 71 can be conveniently mounted on the pump shell 70 along the first conical surface 76, that is, the first conical surface 76 can play a guiding role on the first sealing element 71, so that the mounting difficulty of the first sealing element 71 is reduced, and the assembly efficiency is improved.

In some embodiments, as shown in fig. 3, the mounting cavity 91 has a mounting port 912, and the pump casing 70 is adapted to be mounted in the mounting cavity 91 through the mounting port 912, and the inner circumferential surface of the mounting cavity 91 further includes a second tapered surface 913, the second tapered surface 913 being located on a side of the first annular sealing surface 911 adjacent to the mounting port 912 and being connected to the first annular sealing surface 911, and the inner diameter of the second tapered surface 913 decreasing in a direction approaching the first annular sealing surface 911.

Therefore, by arranging the mounting port 912, and the mounting port 912 is communicated with the mounting cavity 91, the pump shell 70 can be conveniently mounted in the mounting cavity 91 along the mounting port 912, and the second conical surface 913 is arranged, so that the pump shell 70 can be guided, and the mounting difficulty of the pump shell 70 can be reduced.

In some embodiments, as shown in fig. 3, the inner peripheral surface of the mounting cavity 91 includes a first annular end surface 914, the outer peripheral surface of the pump housing 70 includes a second annular end surface 77, the first annular end surface 914 and the second annular end surface 77 are both perpendicular to the axis of the electronic water pump 100, and the first seal 71 is disposed between the first annular end surface 914 and the second annular end surface 77.

Thus, by providing the first annular end surface 914 and the second annular end surface 77 and sandwiching the first seal 71 between the first annular end surface 914 and the second annular end surface 77, the contact area between the first seal 71 and the first annular end surface 914 and the second annular end surface 77, that is, the contact area between the first seal 71 and the pump casing 70 and the mount 90 can be increased, and the sealing effect of the first seal 71 in the axial direction of the electronic water pump 100 can be enhanced.

Meanwhile, the first annular end surface 914 and the second annular end surface 77 are perpendicular to the axis of the electronic water pump 100, so as to play a role in limiting the first sealing element 71 in the axial direction of the electronic water pump 100, and enhance the stability of the first sealing element 71.

In some embodiments, as shown in FIG. 3, the inner circumferential surface of the mounting cavity 91 includes a third annular sealing surface 915, the outer circumferential surface of the pump casing 70 includes a fourth annular sealing surface 78, the third annular sealing surface 915 surrounds the fourth annular sealing surface 78, and the second seal 72 is sandwiched between the third annular sealing surface 915 and the fourth annular sealing surface 78.

That is, the third annular sealing surface 915 is circumferentially disposed radially outward of the fourth annular sealing surface 78, so that the second seal member 72 is disposed between the third annular sealing surface 915 and the fourth annular sealing surface 78, and the second seal member 72 can be restrained by the fourth annular sealing surface 78 radially outward of the electronic water pump 100, and the structural stability of the second seal member 72 can be enhanced, so that the second seal member 72 can serve as a seal between the radially outward of the electronic water pump 100 and the mount 90.

At the same time, the third annular sealing surface 915 surrounds the fourth annular sealing surface 78, enabling the second seal 72 to seal between the pump housing 70 and the mount 90 in the radial direction of the electronic water pump 100.

Further, as shown in FIG. 3, the inner diameter of the third annular sealing surface 915 is W4, the outer diameter of the fourth annular sealing surface 78 is W5, and the width of the second seal member 72 perpendicular to the axial direction of the electronic water pump 100 is W6, 0.1.ltoreq.W 6- (W4-W5))/W6.ltoreq.0.35.

For example: (w6- (W4-W5))/w6=0.15, or (w6- (W4-W5))/w6=0.23, or (W6- (W4-W5))/w6=0.35, that is, when the inner diameter of the third annular sealing surface 915, the outer diameter of the fourth annular sealing surface 78, and the width of the second seal member 72 perpendicular to the axial direction of the electronic water pump 100 satisfy the above-described value ranges, it is possible to ensure that the second seal member 72 has a sufficient sealing effect.

Of course, the above values are merely examples, and are not meant to be limiting.

Further, as shown in fig. 3, the mounting chamber 91 has a mounting port 912, the pump casing 70 is adapted to be mounted in the mounting chamber 91 through the mounting port 912, and the inner circumferential surface of the mounting chamber 91 further includes a third tapered surface 917, the third tapered surface 917 being located on a side of the third annular sealing surface 915 adjacent to the mounting port 912 and being connected to the third annular sealing surface 915, the inner diameter of the third tapered surface 917 decreasing in a direction approaching the third annular sealing surface 915.

Therefore, by arranging the mounting opening 912, the pump casing 70 can be conveniently mounted in the mounting cavity 91 along the mounting opening 912, and by arranging the third conical surface 917, the guiding effect on the pump casing 70 can be achieved, so that the pump casing 70 can be conveniently mounted in the mounting cavity 91 along the mounting opening 912, and the mounting difficulty of the pump casing 70 can be reduced.

In some embodiments, as shown in fig. 3, the inner peripheral surface of the mounting cavity 91 includes a third annular end surface 916, the outer peripheral surface of the pump housing 70 includes a fourth annular end surface 79, the third annular end surface 916 and the fourth annular end surface 79 are each perpendicular to the axis of the electronic water pump 100, and the second seal 72 is disposed between the third annular end surface 916 and the fourth annular end surface 79.

Thus, by providing the third annular end surface 916 and the fourth annular end surface 79 and sandwiching the second seal 72 between the third annular end surface 916 and the fourth annular end surface 79, the contact area between the second seal 72 and the third annular end surface 916 and the fourth annular end surface 79, that is, the contact area between the second seal 72 and the pump case 70 and the mount 90 can be increased, and the sealing effect of the second seal 72 in the axial direction of the electronic water pump 100 can be enhanced.

Meanwhile, the third annular end surface 916 and the fourth annular end surface 79 are perpendicular to the axis of the electronic water pump 100, so as to play a limiting role on the second sealing element 72 in the axial direction of the electronic water pump 100, and enhance the stability of the second sealing element 72.

In some embodiments, as shown in fig. 3, the first liquid inlet 901 is opposite the second liquid inlet 73, and the first liquid outlet 902 is opposite the second liquid outlet 74.

Therefore, no additional connecting pipeline is needed between the first liquid inlet 901 and the second liquid inlet 73 and between the first liquid outlet 902 and the second liquid outlet 74, so that cost is saved, and the electronic water pump 100 is conveniently integrated on the mounting seat 90, so that the miniaturization design of the electronic water pump is realized.
