[0028] [First embodiment]
[0029] like Figure 1-3 The figure shows a motor thermal management module provided by the first embodiment of the utility model, including a base 1, one side of the base 1 is respectively installed with a filter 2, an oil pump 3, an oil cooler 4 and a valve island 5, and the other side of the base 1 is respectively opened with an oil inlet 1A and an oil outlet 1B, the oil inlet 1A is connected to one end of the built-in oil circuit, and the built-in oil circuit is connected to the filter 2, the oil pump 3, the oil cooler 4 and the valve island 5 in sequence, and then the other end is connected to the oil outlet 1B, the module is connected to the motor oil pan through the oil inlet 1A and the oil outlet 1B, the oil in the oil pan enters the base 1 of the thermal management module from the oil inlet 1A, and enters the built-in oil circuit of the base 1, the low-pressure oil passes through the filter 2 and the oil pump 3, and then becomes high-pressure oil, and then enters the oil cooler 4 to realize cooling of the high-pressure and high-temperature oil, and the oil after cooling is controlled by the corresponding valve inside the valve island 5 to timely adjust the amount of oil flowing out of the oil outlet 1B as needed.
[0030] like Figure 1-3As shown, the filter 2 in this embodiment is fixedly mounted on one side of the base 1 through the end cover 21, and the filter 2 is used to filter the oil inside the oil pan. The end cover 21 not only installs and fixes the filter 2, but also effectively seals, prevents dust and protects the internal filter 2.
[0031] The oil pump 3 in this embodiment is a high-pressure electronic pump, which is fixedly installed on one side of the base 1 by means of fixing parts (such as screws or bolts commonly used in the mechanical field) and arranged side by side with the filter 2. The filtered low-pressure oil becomes high-pressure oil through the high-pressure electronic pump.
[0032] The oil cooler 4 is fixedly mounted on one side of the base 1 by means of fixing parts (such as screws or bolts commonly used in the mechanical field), and the oil cooler 4 is connected with a water inlet and a water outlet 1C which are connected to the interior thereof. Low-temperature cooling water enters the interior of the oil cooler 4 through the water inlet, undergoes heat exchange with the high-temperature and high-pressure oil, becomes high-temperature cooling water, and is then discharged from the water outlet; preferably, the water inlet and the water outlet 1C are threadedly connected to the oil cooler 4 to facilitate timely replacement, cleaning and maintenance of the water inlet and the water outlet 1C.
[0033] In this embodiment, the oil inlet 1A and the oil outlet 1B are arranged on the same side of the base 1, and the water inlet and the water outlet 1C are arranged on the other side of the base 1, so as to distinguish the oil inlet and outlet positions and the water inlet and outlet positions from each other, while maximizing the contact path between the oil and the cooling water inside the oil cooler 4, thereby further increasing the cooling efficiency.
[0034] The valve island 5 in this embodiment includes a valve block 54, a solenoid valve 51 is arranged on one side of the valve block 54, and a one-way valve 52 is arranged inside the valve block 54. A simple throttling oil circuit composed of the solenoid valve and the one-way valve can achieve the motor cooling effect, and is decoupled from the flow control valve. If a flow valve fails, the requirement of on-demand cooling of the motor in the multi-motor drive system can be achieved. The valve island 5 also includes a sensor 53 arranged on the valve block 54 to detect the oil flow in real time.
[0035] The specific working process of this embodiment is as follows:
[0036] The oil in the motor oil pan enters the base 1 of the thermal management module from the oil inlet 1A. After passing through the built-in oil circuit of the base 1, the low-pressure oil is filtered by the filter 2 and pressurized by the oil pump 3 to become high-pressure oil, and then enters the oil cooler 4. There is cooling water flowing between the fins on the oil cooler 4 to cool the high-pressure and high-temperature oil through heat exchange. The cooled oil enters the valve island 5, and then the solenoid valve inside the valve island 5 is controlled to adjust the oil volume of multiple oil outlets as needed.
