Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In the electronic control module, the components that need heat dissipation include the power module and the capacitor module. The heat generated by the capacitor module during operation needs to pass through the capacitor cover, heat conductive medium, water channel cover and other structures before it can be transferred to the cooling medium in the water channel. The heat conduction path is long, resulting in low heat dissipation efficiency.
[0033] Based on the above problems, the utility model proposes an electric control module, which aims to shorten the heat conduction path of the capacitor module to improve the heat dissipation effect.
[0034] See also Figure 1 In one embodiment of the utility model, the electric control module 100 includes a power module 10, a water channel 20, a capacitor module 30 and an integrated cover plate 40; the water channel 20 is arranged on one side of the power module 10 and is thermally connected to the power module 10; the capacitor module 30 is arranged on the side of the water channel 20 away from the power module 10; the integrated cover plate 40 is arranged between the water channel 20 and the capacitor module 30, the integrated cover plate 40 includes a capacitor cover plate 41 and a water channel cover plate 42 integrated with the capacitor cover plate 41, the water channel cover plate 42 is covered on the side of the water channel 20 close to the capacitor module 30 and is thermally connected to the water channel 20, and the capacitor cover plate 41 is covered on the side of the capacitor module 30 close to the water channel 20 and is thermally connected to the capacitor module 30.
[0035] The technical solution of the utility model integrates the water channel cover plate 42 on the capacitor cover plate 41 to form an integrated cover plate 40, and at the same time eliminates structures such as the heat conductive medium between the water channel cover plate 42 and the capacitor cover plate 41. In this way, the heat generated by the capacitor module 30 during operation only needs to pass through the integrated cover plate 40 to be transferred to the cooling medium of the water channel 20, which can effectively shorten the heat conduction path of the capacitor module 30, thereby effectively improving the heat dissipation effect.
[0036] In addition, since the use of structures such as the heat-conducting medium between the water channel cover plate 42 and the capacitor cover plate 41 is eliminated, the volume of the electric control module 100 can be made smaller, which can not only achieve a miniaturized design but also reduce the manufacturing cost.
[0037] As some examples, the capacitor module 30 may include a capacitor plastic shell 31 and a bus capacitor 32. The capacitor cover plate 41 is covered on the side of the capacitor plastic shell 31 close to the water channel 20, and is enclosed with the capacitor plastic shell 31 to form an installation cavity. The bus capacitor 32 is installed in the installation cavity to ensure the safety of the bus capacitor 32.
[0038] In actual application, the power module 10 can be fixed to one side of the water channel 20 by means of screws, clips, etc., so as to be thermally connected to the water channel 20. In this way, the heat generated by the power module 10 during operation can be transferred to the cooling medium in the water channel 20, so that the heat of the power module 10 can be taken away by the cooling medium, thereby achieving the purpose of rapid heat dissipation.
[0039] In actual application, the water channel cover plate 42 can be integrated on the capacitor cover plate 41 by one-piece molding, or by screw connection, bonding, clamping, etc.
[0040] Furthermore, the water channel cover plate 42 may be specifically integrated on a surface of a side of the capacitor cover plate 41 close to the water channel 20 , or may be integrated on a periphery of the capacitor cover plate 41 .
[0041] In actual application, the water channel cover plate 42 can be welded to the water channel 20 by means of stir friction welding, or connected to the water channel 20 by means of glue dispensing, or connected to the water channel 20 by means of screw connection, etc. Similarly, the capacitor cover plate 41 can be welded to the capacitor module 30 by means of stir friction welding, or connected to the water channel 20 by means of glue dispensing, or connected to the capacitor module 30 by means of screw connection, etc.
[0042] See also Figure 1 In one embodiment of the present utility model, the water channel cover plate 42 is integrated on a side surface of the capacitor cover plate 41 close to the water channel 20 .
[0043] Such a configuration can increase the contact area between the water channel cover plate 42 and the capacitor cover plate 41, so that the heat transferred from the capacitor module 30 to the capacitor cover plate 41 can be quickly transferred to the water channel cover plate 42, and then transferred to the water channel 20 through the water channel cover plate 42, so that the heat dissipation efficiency can be improved.
[0044] See also Figure 1 In one embodiment of the present utility model, the water channel cover plate 42 and the capacitor cover plate 41 are an integrally formed structure.
[0045] Such a configuration can make the thermal contact between the water channel cover plate 42 and the capacitor cover plate 41 more stable, and can ensure the heat conduction effect between the capacitor cover plate 41 and the water channel cover plate 42. At the same time, the one-piece molding design can not only improve the connection strength between the water channel cover plate 42 and the capacitor cover plate 41, but also simplify the preparation process.
[0046] See also Figure 1 In one embodiment of the utility model, a first water trough (not shown) is provided on one side of the waterway 20 close to the integrated cover plate 40, and a first sealing ring 50 cooperating with the waterway cover plate 42 is provided circumferentially at the connection between the first water trough and the waterway cover plate 42.
[0047] In this way, the first sealing ring 50 can improve the sealing performance of the connection between the water channel cover plate 42 and the water channel 20, thereby preventing the cooling medium flowing through the first water tank from leaking outward from the connection between the water channel cover plate 42 and the water channel 20 and affecting the use effect.
[0048] As some exemplary embodiments, the water channel 20 may be provided with a liquid inlet and a liquid outlet connected to the first water tank, and the cooling medium enters the first water tank from the liquid inlet and is discharged to the outside through the liquid outlet.
[0049] As some exemplary embodiments, the first sealing ring 50 may be a rubber ring or a silicone ring.
[0050] See also Figure 1 In one embodiment of the utility model, a sealing groove 421 is provided on one side of the waterway cover plate 42 close to the waterway 20 , and a portion of the first sealing ring 50 is disposed in the sealing groove 421 .
[0051] By configuring in this way, by partially installing the first sealing ring 50 in the sealing groove 421 , the installation stability of the first sealing ring 50 can be improved to ensure the sealing performance of the connection between the water channel cover plate 42 and the water channel 20 .
[0052] See also Figure 1 In one embodiment of the utility model, a matching water tank 422 is further provided on one side of the waterway cover plate 42 close to the waterway 20 . The matching water tank 422 is connected to the first water tank, and the sealing groove 421 is arranged around the matching water tank 422 .
[0053] In this way, by providing a matching water groove 422 connected to the first water groove on the water channel cover plate 42, the cooling medium flowing through the first water groove can enter the matching water groove 422 of the water channel cover plate 42, so as to increase the contact area between the cooling medium and the water channel cover plate 42, and can more quickly take away the heat conducted to the water channel cover plate 42, thereby further improving the heat dissipation effect of the capacitor module 30.
[0054] In actual application, the matching water channel 20 may pass through to the side where the water channel cover plate 42 and the capacitor cover plate 41 are connected, or may not pass through to the side where the water channel cover plate 42 and the capacitor cover plate 41 are connected.
[0055] Furthermore, the cross-sectional shape of the matching water tank 422 may include, but is not limited to, circular, elliptical, rectangular, pentagonal, hexagonal, and other shapes.
[0056] See also Figure 1 In one embodiment of the present utility model, the matching water tank 422 passes through to the side where the water channel cover plate 42 is connected to the capacitor cover plate 41.
[0057] With such a configuration, the cooling medium flowing through the matching water trough 422 can not only directly contact the water channel cover 42, but also directly contact the capacitor cover 41, and can directly take away the heat conducted to the capacitor cover 41, so as to further shorten the heat conduction path of the capacitor module 30, so that the heat dissipation effect of the capacitor module 30 can be further improved.
[0058] As some exemplary embodiments, the water channel cover plate 42 may be an annular structure, and the hollowed-out position in the middle of the annular structure is used to match the water tank 422 .
[0059] See also Figure 1 In one embodiment of the present invention, the waterway cover plate 42 is connected to the waterway 20 via a locking structure.
[0060] With such arrangement, the waterway cover plate 42 is directly connected to the waterway 20 by using a locking structure, and the use of the first sealing ring 50 can replace the stir friction welding or glue dispensing method to connect the waterway cover plate 42 to the waterway 20, which makes the process simpler and easier to install.
[0061] As some exemplary embodiments, the locking structure may be a screw or a pin.
[0062] See also Figure 1 In one embodiment of the utility model, a second water tank 21 is provided on one side of the water channel 20 close to the power module 10 , and a second sealing ring 60 cooperating with the power module 10 is provided in the circumference of the connection between the second water tank 21 and the power module 10 .
[0063] In this way, the second sealing ring 60 can improve the sealing performance of the connection between the power module 10 and the water channel 20, and prevent the cooling medium flowing through the second water tank 21 from leaking outward from the connection between the power module 10 and the water channel 20 to affect the use effect.
[0064] In actual application, the first water tank and the second water tank 21 of the water channel 20 may be connected to each other or may not be connected to each other.
[0065] As some examples, the water channel 20 may be provided with a liquid inlet and a liquid outlet connected to the second water tank 21, and the cooling medium enters the second water tank 21 from the liquid inlet and is discharged outward through the liquid outlet. When the first water tank and the second water tank 21 are connected to each other, the first water tank and the second water tank 21 may share a liquid inlet and a liquid outlet.
[0066] As some exemplary embodiments, the second sealing ring 60 may be a rubber ring or a silicone ring.
[0067] In actual application, the power module 10 may be provided with one or at least two, depending on the actual use requirements. Correspondingly, the second water tank 21 and the second sealing ring 60 may also be provided with one or at least two.
[0068] The utility model also proposes an electric drive assembly, which includes a motor and an electric control module 100. The specific structure of the electric control module 100 refers to the above embodiment. Since the electric drive assembly adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the electric control module 100 is used to drive the motor to work.
