The power supply thermal management system of the embodiment of the application can be applied to protecting a power supply system with a large battery and also can be applied to testing the heat dissipation condition of the battery. Large batteries, such as automotive fuel cells, are difficult to naturally dissipate heat generated during use due to the large volume and complex structure, and safety accidents are easily caused by excessive heat of the batteries, so that a special cooling system is required to cool the batteries. In the related art, when a power supply system with a large battery is used for replacing the battery, a cooling system pipeline is generally directly detached, and if the cooling system pipeline is directly detached, cooling liquid is easy to flow and difficult to collect and recycle due to direct connection of the power supply system and the cooling system, so that resource waste is caused, and material cost is increased.

In some embodiments, referring to fig. 1, a power thermal management system includes: a power module 100, a cooling module 200, a first valve module 300, and a second valve module 400; the cooling module 200 is used for radiating heat of the cooling liquid flowing through the cooling module 200; one end of the first valve module 300 is connected with the input end of the cooling module 200, and the other end of the first valve module 300 is connected with the power module 100; one end of the second valve module 400 is connected with the output end of the cooling module 200, and the other end of the second valve module 400 is connected with the power module 100; wherein the first valve module 300 and the second valve module 400 are used to control the flow of coolant between the power module 100 and the cooling module 200.
When the battery of the power module 100 needs to be replaced, the valves of the first valve module 300 and the second valve module 400 are adjusted to close the channel between the power module 100 and the cooling module 200, and the valves capable of discharging the residual cooling liquid of the power module 100 are opened by the first valve module 300 and the second valve module 400, so that the cooling liquid is discharged into an external container to be collected, and the collected cooling liquid can be reused, thereby reducing the waste of the cooling liquid.

Referring to fig. 1 and 3, the first valve module 300 includes a first two-way valve 310, a second two-way valve 320, and a first three-way joint 330, a first end of the first three-way joint 330 is connected to one end of the first two-way valve 310, another end of the first two-way valve 310 is connected to an input end of the cooling module 200, a second end of the first three-way joint 330 is connected to one end of the second two-way valve 320, and a third end of the first three-way joint 330 is connected to the power module 100; wherein the first two-way valve 310 is used for controlling the flow of the cooling fluid of the cooling module 200 to the power module 100, and the second two-way valve 320 is used for controlling the discharge of the cooling fluid of the power module 100. The two-way valve of the embodiment of the application comprises: an electrically controlled valve and a ball valve.
Referring to fig. 1 and 3, the second valve module 400 includes a third two-way valve 410, a fourth two-way valve 420, and a second three-way joint 430, a first end of the second three-way joint 430 is connected to one end of the third two-way valve 410, another end of the third two-way valve 410 is connected to an output end of the cooling module 200, a second end of the second three-way joint 430 is connected to one end of the fourth two-way valve 420, and a third end of the second three-way joint 430 is connected to the power module 100, wherein the third two-way valve 410 is used to control a flow of coolant from the cooling module 200 to the power module 100, and the fourth two-way valve 420 is used to control a discharge of coolant from the power module 100.
When the battery of the power module 100 needs to be replaced. The first and third two-way valves 310 and 410 are controlled to be closed, the flow of the cooling fluid between the cooling module 200 and the power module 100 is stopped, and the cooling fluid of the power module 100 is collected by controlling the second and fourth two-way valves 320 and 420 to be opened. Therefore, by providing the first, second, third, and fourth two-way valves 310, 320, 410, and 420 between the power module 100 and the cooling module 200, the coolant can be collected during battery replacement, thereby reducing resource waste and material costs.
In some embodiments, referring to fig. 3, the cooling module 200 includes at least two heat sinks and at least two valve units, one valve unit connected to an input of one heat sink, the valve units for controlling a flow of cooling fluid through the heat sink. The cooling module 200 further includes a distribution manifold, where each output of the distribution manifold is configured to connect to a heat sink, the input of the distribution manifold is the input of the cooling module 200, and the common output of all the heat sinks is the output of the cooling module 200. In the related art, a plurality of heat sinks in a battery cooling system are generally used in parallel, and all the heat sinks work simultaneously, so that the heat dissipation capacity is large, and the temperature of the cooling liquid is greatly reduced. In some scenes of low-power heat dissipation, the temperature fluctuation range of the cooling liquid is larger, and the temperature control of the whole system is not facilitated. The cooling module 200 of the embodiment of the application is provided with a valve unit at the input end of each radiator to control the flow of the cooling liquid of the radiator so as to realize the combination and collocation work of a plurality of radiators. The smaller the flow rate of the cooling liquid flowing through the radiator, the more remarkable the temperature drop of the cooling liquid. When it is not required that all the radiators are operated, the passages of the corresponding valve units may be closed. The valve unit may be a single valve such as a two-way valve or may be a combination of valves. Referring to fig. 3, the valve unit of the present embodiment is constituted by one two-way valve. When the power supply heat management system is applied to the heat dissipation condition test of the battery, grouping of the radiators and control of the coolant flow are achieved through the valve unit, the working quantity of the radiators can be distributed in a self-defined mode, and the heat dissipation requirements of the battery system with multiple power platforms can be matched. In one embodiment, referring to fig. 3, a two-way valve (valve unit) may be provided at the output of each radiator to further control the coolant output flow rate of the radiator.
In some embodiments, referring to fig. 4, the radiator is provided with at least two heat dissipation fans, each of which is connected to a driving unit (not shown), and adjusts the rotation speed according to a driving signal of the driving unit. The driving unit is a device or a circuit module for driving the cooling fan to rotate. The rotating speed of each fan is finely controlled through the plurality of driving units, so that the working state of the radiator can be better controlled, and the temperature fluctuation range of the cooling liquid is reduced. In an exemplary embodiment, the driving signal may be a PWM (Pulse Width Modulation ) signal, and the rotational speed of the fan is controlled by adjusting the waveform of the driving signal.
In some embodiments, referring to fig. 2 and 3, the power thermal management system further includes a mixing module 500, an input of the mixing module 500 is connected to an output of each heat sink, and an output of the mixing module 500 is connected to the second valve module 400. As shown in fig. 3, the output end of the mixing module 500 is provided with a temperature sensor for detecting the temperature of the mixed coolant so as to control the rotation speed of the radiator according to the temperature of the coolant. In the related art, the output ends of the plurality of heat sinks in the cooling system of the battery are simply combined, and then the mixed cooling liquid is used for cooling the battery. The cooling liquid in this case is not uniformly mixed, and the temperature of the cooling liquid detected by the corresponding temperature sensor cannot truly reflect the temperature of the cooling liquid passing through the radiator, thereby affecting the subsequent control of the operating state of the radiator. According to the embodiment of the application, the mixing module 500 is arranged at the output end of the cooling module 200, so that the cooling liquid flowing out of different radiators can be fully and uniformly mixed, and the effectiveness of the detection result of the temperature sensor is ensured.
In some embodiments, referring to fig. 2 and 4, the power thermal management system further includes a pneumatic module 600, an input of the pneumatic module 600 is connected to an output of each heat sink, and an output of the pneumatic module 600 is connected to an input of the hybrid module 500.
In some embodiments, referring to fig. 4, the air compression module 600 includes a fifth two-way valve 610, an air compression radiator, a third three-way joint 620, a fourth three-way joint 630, a booster, an air compressor, and an air compression controller, wherein one end of the fifth two-way valve 610 is connected to an output end of each radiator, the other end of the fifth two-way valve 610 is connected to an input end of the air compression radiator, an output end of the air compression radiator is connected to a first end of the third three-way joint 620, a second end of the third three-way joint 620 is connected to one end of the air compression controller, a third end of the third three-way joint 620 is connected to one end of the booster, the other end of the booster is connected to a first end of the fourth three-way joint 630, the other end of the air compression controller is connected to one end of the air compressor, and the other end of the air compressor is connected to a second end of the fourth three-way joint 630. In the related art, since the air compressors have different operating temperatures, the cooling circulation system is generally separately provided, and the cooling circulation system is not shared with other devices having different operating temperatures. The power supply thermal management system of the embodiment of the application distributes part of the cooling liquid output by the cooling module 200 to the air compressor module 600 through one two-way valve, so as to cool the air compressor, the air compressor controller and the booster, and conveys the cooling liquid flowing out of the air compressor module 600 to the mixing module 500 to be fully and uniformly mixed with the cooling liquid output by the cooling module 200, thereby ensuring that the power supply thermal management system normally performs the cooling operation of the power supply module 100, realizing the effect that different working temperature devices share the same cooling circulation route, avoiding independently setting the cooling system of the air compressor, and reducing equipment cost.
In some embodiments, referring to fig. 3 or 4, the power thermal management system further includes a coolant filter, the cooling module 200 further includes a deionizer and an expansion tank, an input of the deionizer is connected to each radiator, an input of the expansion tank is connected to an output of the deionizer and the power module 100, respectively, one end of the coolant filter is connected to an output of the expansion tank and an output of the radiator, and the other end of the coolant filter is connected to the second valve module 400. The cooling liquid consists of water, antifreezing agent and additive. The deionizer is used to remove conductive ions. In battery operation, a high voltage is generated across the bipolar plates, but at the same time it is required that this high voltage is not transferred through the cooling fluid in the middle of the bipolar plates to the entire cooling circulation flow channels, and therefore it is required that the cooling fluid is not electrically conductive. When the cooling liquid flows through the radiator and the power module 100, a part of water is vaporized to be gas, the gas water is contained in the expansion tank and condensed into liquid water, and the liquid water is conveyed back to the cooling circulation loop by gravity. The expansion tank is therefore usually arranged at the highest point of the system.
In some embodiments, referring to fig. 3 or 4, the power module 100 includes a battery and a water pump, an input terminal of the water pump is connected to the second valve module 400, an output terminal of the water pump is connected to one end of the battery, and the other end of the battery is connected to the first valve module 300. The water pump is used for driving the cooling liquid to circularly flow in the system. The cell may be a fuel cell stack. Referring to fig. 4, temperature sensors are provided at both sides of the battery to monitor the cooling effect of the system on the battery.
