[0032] The embodiments of the present application provide a heating module 100 applied to a thermal management system of a vehicle. When the temperature of the liquid in the thermal management system is too low, the heating module 100 can heat the liquid through a heat exchange water circuit 13 to ensure that the temperature of the liquid in the thermal management system is maintained within a certain range, thereby ensuring that the key components such as the battery can still be maintained within the optimal temperature range when the vehicle is powered off.

[0033] Please refer to Figures 1 to 4 In the heating module 100 provided by the embodiments of the present application, the heating module 100 includes a housing assembly 10, a high-pressure heating assembly 20 and a low-pressure heating assembly 30. The housing assembly 10 is provided with a heat exchange water circuit 13. When the heating module 100 is applied to the thermal management system of a vehicle, the heat exchange water circuit 13 communicates with the heat exchange pipelines of other devices of the thermal management system, that is, the liquid in the thermal management system can flow through the heat exchange water circuit 13 of the heating module 100.

[0034] The high-voltage heating assembly 20 is mounted on the outer surface of the shell assembly 10 and is electrically connected to the high-voltage power supply system of the automobile to heat the shell assembly 10 under the high-voltage power supply of the high-voltage power supply system of the automobile. It should be noted that in the automobile, when the vehicle is turned off and the entire vehicle is powered off, the high-voltage power supply system of the automobile stops working, and the high-voltage heating assembly 20 is powered by the high-voltage power supply system of the automobile. Therefore, the high-voltage heating assembly 20 cannot work normally when the entire vehicle is powered off. When the vehicle is started and the entire vehicle is powered on, the high-voltage power supply system of the automobile works normally, and the high-voltage heating assembly 20 can work normally under the high-voltage power supply of the high-voltage power supply system of the automobile.

[0035] The low-voltage heating assembly 30 is mounted on the outer surface of the shell assembly 10 and is electrically connected to the low-voltage power supply system of the automobile to heat the shell assembly 10 under the low-voltage power supply of the low-voltage power supply system of the automobile. It should be noted that in the automobile, when the vehicle is turned off and the entire vehicle is powered off, most electrical equipment will be powered off, but in order to ensure the safety and basic functions of the vehicle, the low-voltage power supply system of the automobile still maintains a normal working state. In order to ensure the normal power supply of the devices that ensure the safety and basic functions of the vehicle, these devices are usually referred to as "always-on" devices.

[0036] The heating module 100 provided by the embodiment of the present application has not only the high-voltage heating assembly 20 powered by the high-voltage power supply system of the automobile and maintaining normal work, but also the low-voltage heating assembly 30 powered by the low-voltage power supply system of the automobile and maintaining normal work. When the vehicle is turned off and the entire vehicle is powered off, and the vehicle needs to heat the battery and other components, the heating module 100 needs to heat the liquid in the heat exchange waterway 13. At this time, the low-voltage heating assembly 30 of the heating module 100 can maintain normal work under the low-voltage power supply of the low-voltage power supply system of the automobile, and then heat the liquid in the heat exchange waterway 13 to meet the heating demand of the vehicle.

[0037] In some examples, as shown in Figures 2 to 4 The shell assembly 10 has a first mounting surface 14 and a second mounting surface 15 arranged opposite to each other, the first mounting surface 14 is provided with the high-voltage heating assembly 20, and the second mounting surface 15 is provided with the low-voltage heating assembly 30. In this way, the overall layout of the heating module 100 is optimized, and the installation of the high-voltage heating assembly 20 and the low-voltage heating assembly 30 is facilitated.

[0038] In some examples, as shown in Figures 2 to 4 The high-voltage heating assembly 20 includes a high-voltage heat-conducting gasket 21 and a high-voltage heating plate 22, the high-voltage heat-conducting gasket 21 is fixedly installed on the shell assembly 10 and tightly abuts against the first mounting surface 14, and the high-voltage heating plate 22 tightly abuts against one side of the high-voltage heat-conducting gasket 21 away from the first mounting surface 14. In this way, the area of contact between the high-voltage heating assembly 20 and the shell assembly 10 is increased by the high-voltage heat-conducting gasket 21, and the heat conduction efficiency is improved.

[0039] It is emphasized that the number of high-pressure heat-conducting pads 21 and high-pressure heating plates 22 can be more than two, in the example shown in Figure 2 The high-temperature heating assembly includes two high-pressure heat-conducting pads 21 and two high-pressure heating plates 22.

[0040] In some examples, the first mounting surface 14 is provided with a first positioning portion, and the high-pressure heat-conducting pad 21 is provided with a first matching portion that is in concave-convex matching with the first positioning portion. Specifically, in some examples, the first mounting surface 14 is concavely provided with a mounting groove to form the first positioning portion, and the high-pressure heat-conducting pad 21 is at least partially accommodated in the mounting groove. In yet another example, the first mounting surface 14 is convexly provided with two positioning ribs, and the two positioning ribs and the part of the first mounting surface 14 between the two positioning ribs enclose a mounting groove to form the first positioning portion, and the high-pressure heat-conducting pad 21 is at least partially accommodated in the mounting groove.

[0041] Such an arrangement is intended to further facilitate the installation of the high-pressure heating assembly 20 on the shell assembly 10. Meanwhile, the concave-convex matching of the first matching portion with the first positioning portion can define the installation position of the high-pressure heat-conducting pad 21, avoiding its displacement.

[0042] In some examples, as shown in Figures 2 to 4 The low-pressure heating assembly 30 includes a low-pressure heat-conducting pad 31 and a low-pressure heating plate 32. The low-pressure heat-conducting pad 31 is fixedly installed on the shell assembly 10 and tightly abuts against the first mounting surface 14, and the low-pressure heating plate 32 tightly abuts against the side of the low-pressure heat-conducting pad 31 away from the shell assembly 10. Such an arrangement is intended to increase the area of contact between the low-pressure heating assembly 30 and the shell assembly 10 through the low-pressure heat-conducting pad 31, thereby improving the heat conduction efficiency.

[0043] It is emphasized that the number of low-pressure heat-conducting pads 31 and low-pressure heating plates 32 can be more than two, in the example shown in Figure 2 The low-temperature heating assembly includes two low-pressure heat-conducting pads 31 and two low-pressure heating plates 32.

[0044] In some examples, the second mounting surface 15 is provided with a second positioning portion, and the low-pressure heat-conducting pad 31 is provided with a second matching portion that is in concave-convex matching with the second positioning portion. Specifically, in some examples, the second mounting surface 15 is concavely provided with a mounting groove to form the second positioning portion, and the low-temperature heat-conducting pad is at least partially accommodated in the mounting groove. In yet another example, the second mounting surface 15 is convexly provided with two positioning ribs, and the two positioning ribs and the part of the second mounting surface 15 between the two positioning ribs enclose a mounting groove to form the second positioning portion, and the low-temperature heat-conducting pad is at least partially accommodated in the mounting groove.

[0045] In this way, the low-pressure heating assembly 30 is further facilitated to be installed in the shell assembly 10, and the first matching part and the first positioning part are matched in concave-convex mode to define the installation position of the low-pressure heat-conducting gasket 31, thereby avoiding the low-pressure heat-conducting gasket 31 from being moved.

[0046] In some examples, as shown in Figures 1 to 3 The heating module 100 further includes a shell assembly 40 and a thermal insulation cotton 50. The shell assembly 40 is provided with a mounting cavity 41, and the thermal insulation cotton 50 is arranged on the cavity wall of the mounting cavity 41. The shell assembly 10, the high-pressure heating assembly 20, and the low-pressure heating assembly 30 are all installed in the mounting cavity 41.

[0047] In this way, the shell assembly 40 is kept warm by the thermal insulation cotton 50, heat dissipation is reduced, and energy utilization is improved. At the same time, heat is reduced to the shell assembly 40, and the risk of high-temperature scalding is reduced.

[0048] In some examples, as shown in Figures 2 to 4 The shell assembly 10 has a third mounting surface 16 and a fourth mounting surface 17 arranged opposite to each other. The third mounting surface 16 is respectively provided with a liquid inlet 161 and a liquid outlet 162 in communication with the heat exchange waterway 13. The heating module 100 further includes a high-voltage wire 60 and a low-voltage wire 70. The high-voltage wire 60 is electrically connected to the high-pressure heating assembly 20 on the side of the shell assembly 10 located at the fourth mounting surface 17. The low-voltage wire 70 is electrically connected to the low-pressure heating assembly 30 on the side of the shell assembly 10 located at the fourth mounting surface 17.

[0049] In this way, the overall layout of the heating module 100 is optimized, the heat exchange waterway 13 of the heating module 100 is facilitated to be in communication with the heat exchange waterway 13 of other components of the thermal management system, and at the same time, the high-pressure heating assembly 20 is facilitated to be electrically connected to the high-voltage power supply system of the automobile through the high-voltage wire 60, and the low-pressure heating assembly 30 is facilitated to be electrically connected to the low-voltage power supply system of the automobile through the low-voltage wire 70. In addition, the risk of short circuit of the heating module 100 caused by liquid leakage of the heat exchange waterway 13 is also reduced.

[0050] It should be emphasized that the shell assembly 40 is respectively provided with the avoiding holes for the liquid inlet 161 and the liquid outlet 162 to be exposed on the surface of the shell assembly 40. The shell assembly 40 is further provided with wire holes for the high-voltage wire 60 and the low-voltage wire 70 to extend out.

[0051] It should be emphasized that the material of the shell assembly 10 is usually aluminum. In some examples, as shown in Figures 2 to 5As shown, the shell assembly 10 comprises a base 11 and a cover 12, the base 11 is concavely provided with a water groove 111, two ends of the water groove 111 are respectively communicated with a liquid inlet 161 and a liquid outlet 162, the cover 12 is connected with the base 11 and covers the water groove 111 to form a heat exchange water path 13. In this way, the processing and installation of the shell assembly 10 are facilitated.

[0052] In some examples, as shown in FIG. 1, the heat exchange water path 13 is provided with a plurality of heat exchange units 14, and the heat exchange units 14 are arranged in the heat exchange water path 13 in a staggered manner. Figures 2 to 5 As shown, the bottom wall of the water groove 111 is also convexly provided with a water distribution rib 112, and the water distribution rib 112 is also arranged along the extension direction of the heat exchange water path 13. In this way, the water distribution rib 112 divides part of the heat exchange water path 13 into two branches, so that the shell assembly 10 increases the contact area with the liquid in the heat exchange water path 13, thereby improving the heat conduction efficiency of the shell assembly 10 to the liquid.

[0053] In some examples, the heat exchange water path 13 is curved back and forth to further increase the contact area of the shell assembly 10 with the liquid in the heat exchange water path 13.
