Description

Technical Field

[0002] With the increasing severity of energy shortage and environmental pollution, new energy vehicles have become a research hotspot for major automobile manufacturers and research and development institutions around the world. Among them, fuel cells are generally considered to have broad development prospects due to their high efficiency and near-zero emissions. Proton exchange membrane fuel cell (PEMFC) is a fuel cell that uses hydrogen and air as fuel to generate electricity. It does not require a combustion reaction of hydrogen and oxygen, but uses a proton exchange membrane as an electrolyte to directly convert the chemical energy of hydrogen and oxygen into electrical energy. It has the characteristics of high energy efficiency, zero emissions, low noise, and reliable continuous load operation.

[0003] In order to avoid problems such as pipe icing and blockage caused by the inability to discharge liquid water out of the vehicle in time in cold areas, a muffler with a gas-liquid separation structure is usually used to separate the liquid water and gas discharged by the fuel cell. The liquid water is directly discharged out of the vehicle, and the gas is discharged out of the vehicle through the muffler structure. Gas-liquid separators are generally divided into two categories: cyclone type and baffle type. The cyclone type relies on centrifugal force to throw the mixed gas to the inner wall to achieve the purpose of gas-liquid separation; the baffle type uses the structural design of the flow channel to allow the mixed gas to achieve the purpose of gas-liquid separation through condensation and gravity during the flow process. Among them, the baffle type gas-liquid separator generally leaves a box at the bottom, and the box has a drain port to discharge the separated liquid out of the box. However, in a low temperature environment, the liquid remaining in the box will freeze and block the drain port, resulting in the inability to discharge the liquid from the box, and there is room for improvement.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Reference below Figure 1-Figure 2 The gas-liquid separation device 102 according to the embodiment of the utility model is described. The gas-liquid separation device 102 can realize the effective recovery and reuse of braking heat, ensure that the liquid water separated in the water storage chamber 13 can be discharged continuously, and effectively avoid the problem of liquid water freezing and clogging the water storage chamber 13 due to low temperature.

[0032] like Figure 1-Figure 2 As shown, the gas-liquid separation device 102 according to the embodiment of the utility model includes: a gas-liquid separator 1, a braking module 2, an energy storage component 31 and a heating flow path 3.

[0033] The gas-liquid separator 1 is used to separate gas and liquid. In practice, the gas-liquid separator 1 can be constructed as a hollow cylindrical structure, a square structure, etc., so that a gas-liquid separation chamber 12 and a water storage chamber 13 can be formed inside. The gas-liquid separation chamber 12 is used to effectively separate gas (such as hydrogen or air, etc.) and liquid (such as water, etc.) so that they can be discharged separately to prevent gas and liquid from entering other components and causing damage. The water storage chamber 13 is mainly used to collect and store the liquid separated from the gas-liquid separation chamber 12 and discharge it, wherein the water storage chamber 13 is located below the gas-liquid separation chamber 12 and is connected to the gas-liquid separation chamber 12, that is, the liquid separated from the gas-liquid separation chamber 12 can directly enter the water storage chamber 13 below, thereby facilitating the accumulation and discharge of the liquid. When the liquid in the water storage chamber 13 accumulates to a certain extent, it can be discharged from the water storage chamber 13.

[0034] A heating chamber 14 is also formed in the gas-liquid separator 1 and is distributed around the water storage chamber 13, that is, the heating chamber 14 can heat the liquid water in the water storage chamber 13 to prevent the liquid water from forming ice cubes or accumulating too much condensed water in the water storage chamber 13 under low temperature environment, thereby blocking the drainage of the water storage chamber 13 and causing the liquid water to be unable to be discharged to the outside. The heating chamber 14 is distributed around the water storage chamber 13, and can heat the water in the water storage chamber 13 evenly and comprehensively, thereby improving the heating efficiency, thereby ensuring the normal operation of the gas-liquid separation device 102 under low temperature environment.

[0035] Furthermore, the energy storage component 31 includes a heating flow path 3, and the heat generated by the braking module 2 is suitable for being transported to the heating flow path 3. The heating flow path 3 is connected to the heating chamber 14, and the heating flow path 3 contains a heating medium suitable for flowing to the heating chamber 14.

[0036] Specifically, the energy storage component 31 can store and release energy. The brake module 2 will generate a large amount of heat during the braking process. The generated heat can be transported to the heating flow path 3 in the energy storage component 31, so as to store and utilize the braking heat generated in the brake module 2, thereby improving the utilization efficiency of heat. The heating medium in the heating flow path 3 has good thermal conductivity and can absorb and transfer heat. Therefore, the heating medium after absorbing the heat can circulate in the heating flow path 3 and flow into the heating chamber 14. Thus, the heat generated by the brake module 2 is transferred to the heating chamber 14 through the heating medium, so that the temperature of the heating chamber 14 increases, so that the water storage chamber 13 can be continuously heated, so that the liquid water in the water storage chamber 13 can be discharged in time, and the residual liquid water is prevented from forming ice cubes in the water storage chamber 13 to block the water storage chamber 13. The high temperature accelerates the evaporation of water, greatly improving the efficiency of discharging liquid water, thereby realizing the effective recovery and reuse of braking heat, effectively utilizing energy, and no other heating device is required, thereby reducing costs and saving energy.

[0037] Among them, it should be noted that the heating medium needs to have good thermal conductivity and temperature stability, and be able to remain stable and effectively transfer heat within the operating temperature range of the system. In practice, the heating medium can be selected as water, glycerin, methyl silicone oil, phenyl silicone oil, etc., to achieve efficient brake heat recovery and reuse.

[0038] According to the gas-liquid separation device 102 of the embodiment of the utility model, by providing a connected heating flow path 3 and a heating chamber 14, the heat generated by the braking of the brake module 2 can be transported to the heating flow path 3, and the braking heat is transmitted to the heating chamber 14 by the heating medium in the heating flow path 3, and heat exchange is carried out with liquid water in the heating chamber 14 to achieve continuous heating of the water storage chamber 13, thereby achieving effective recovery and reuse of braking heat, ensuring that the liquid water separated in the water storage chamber 13 can be continuously discharged, and effectively avoiding the problem of liquid water freezing and clogging the water storage chamber 13 due to low temperature.

[0039] In some embodiments, the energy storage assembly 31 further includes a heat conductor connected to the heating flow path 3 , the heat conductor 1 is connected to the brake module 2 , and the heat conductor transfers the heat generated by the brake module 2 to the heating medium in the heating flow path 3 .

[0040] That is to say, the braking heat generated by braking in the braking module 2 can be transferred to the heating medium through the heat conductor to heat the medium. After fully absorbing the heat, the heating medium circulates in the heating flow path 3 to the heating chamber 14 to achieve heat transfer. The heat can be efficiently transferred to the heating chamber 14 to heat the liquid water, thereby improving the heat transfer efficiency.

[0041] In some embodiments, the brake module 2 includes a brake disc 21 and a friction plate 22 , the brake disc 21 and the friction plate 22 are in press contact and can move relative to each other, and the heat conductor is connected to at least one of the brake disc 21 and the friction plate 22 .

[0042] Specifically, when braking is required, the brake disc 21 contacts the friction plate 22 and generates friction, and the two generate relative motion, thereby preventing the rotation of the wheel, achieving the deceleration or stop of the vehicle, and converting the vehicle kinetic energy into heat energy through friction. Among them, the heat conductor is connected to at least one of the brake disc 21 and the friction plate 22, that is, the energy storage component 31 can be connected to the brake disc 21, or connected to the friction plate 22, thereby realizing the connection between the brake module 2 and the energy storage component 31, so that the heat generated by the brake disc 21 and the friction plate 22 can be transported to the energy storage component 31 for storage.

[0043] In some embodiments, the gas-liquid separation device 102 also includes a temperature sensor 4 and a control unit 5. A control valve 32 is provided in the heating flow path 3. The control valve 32 and the temperature sensor 4 are electrically connected to the control unit 5 respectively. The temperature sensor 4 is used to detect the ambient temperature. The control unit 5 controls the control valve 32 to selectively open or close according to the temperature detection value of the temperature sensor 4.

[0044] like Figure 1 As shown, the gas-liquid separation device 102 is also provided with a temperature sensor 4 and a control unit 5, a control valve 32 is provided in the heating flow path 3, and the control valve 32 and the temperature sensor 4 are electrically connected to the control unit 5 respectively, that is, signal transmission can be performed between the control valve 32, the temperature sensor 4 and the control unit 5, so that the temperature sensor 4 can detect the temperature of the external environment in real time, and transmit the detected temperature signal to the control unit 5, and the control unit 5 determines the heating mode according to the temperature after receiving the temperature signal, in other words, determines whether the current ambient temperature requires adjustment of the on-off of the heating flow path 3, and if adjustment is required, the control unit 5 sends a corresponding control signal to the control valve 32, and the control valve 32 selectively turns on or off the heating flow path 3 according to the signal, thereby realizing selective heating of the heating chamber 14.

[0045] In practice, when the temperature sensor 4 detects that the external environment temperature is ≤0°C, the control unit 5 can determine to turn on the heating mode, that is, the control valve 32 can be turned on according to the signal of the control unit 5, so that the heating flow path 3 is connected to the heating chamber 14, so that the heating medium after absorbing heat can be transported from the heating flow path 3 to the heating chamber 14, so as to achieve continuous heating of the water storage chamber 13, and ensure that the separated liquid water can be continuously discharged from the water storage chamber 13 in a timely manner, avoiding the problem that the liquid water in the water storage chamber 13 freezes and blocks the water storage chamber 13 due to the low temperature environment, so that the liquid water cannot be discharged in time. Similarly, when the temperature sensor 4 detects that the external environment temperature is greater than 0°C, the control unit 5 can determine not to turn on the heating mode, that is, the control valve 32 can be closed according to the signal of the control unit 5, so that the heating flow path 3 is not connected to the heating chamber 14, and there is no need to heat the water storage chamber 13.

[0046] The control valve 32 can be set as an electromagnetic valve, which is a multi-opening regulating valve, can automatically adjust the opening and closing state, quickly respond to the control unit 5, and accurately control the opening of the valve 32, with high reliability and automation.

[0047] In some embodiments, a driving pump 33 is further provided in the heating flow path 3, and the driving pump 33 is used to drive the heating medium to flow.

[0048] Specifically, Figure 1 As shown, a driving pump 33 is also provided in the heating flow path 3. The driving pump 33 can provide power to drive the heating medium to circulate rapidly in the heating flow path 3, so that the heating medium after absorbing heat can circulate to the heating chamber 14, thereby realizing continuous heating of the water storage chamber 13. The driving pump 33 can make the heating medium flow rapidly in the heating chamber 14, thereby improving the heat exchange efficiency, thereby ensuring the heating uniformity of the water storage chamber 13 and improving the heating efficiency. The driving pump 33 can also control the flow rate of the heating medium, so that the heating medium can flow stably in the heating flow path 3 and the heating chamber 14, thereby ensuring the stability of the gas-liquid separation device 102.

[0049] Therefore, by setting up the driving pump 33, the heating medium can circulate rapidly in the heating flow path 3 and the heating chamber 14, thereby improving the heating efficiency, achieving continuous and efficient heating of the water storage chamber 13, and allowing liquid water to be quickly discharged from the water storage chamber 13.

[0050] In some embodiments, the gas-liquid separator 1 includes a first shell 131 defining a water storage chamber 13, a second shell 132 is further provided outside the first shell 131, and a heating chamber 14 is defined between the first shell 131 and the second shell 132. Figure 2As shown, the water storage chamber 13 can be constructed as a square structure, that is, the first shell 131 and the second shell 132 are both square, the second shell 132 is larger than the first shell 131 so as to be mounted outside the first shell 131, and the first shell 131 and the second shell 132 are separated by a certain distance to form a heating chamber 14, so that the heating chamber 14 is distributed around the water storage chamber 13, and liquid water can be surrounded therein to fully heat the liquid water.

[0051] The second shell 132 is formed with an inlet hole and an outlet hole for connecting the heating chamber 14 to the heating flow path 3, that is, the heating medium can flow with the heating chamber 14 through the inlet hole and the outlet hole to realize the circulation of the heating medium. The first shell 131 and the second shell 132 are also provided with a drain port 133 connected to the water storage chamber 13, that is, the liquid water in the water storage chamber 13 can flow out from the drain port 133 to the outside to realize the discharge of separated liquid water.

[0052] Specifically, during heating, the heating medium in the heating flow path 3 can enter the heating chamber 14 from the water inlet hole on the second shell 132 and circulate in the heating chamber 14 to uniformly heat the liquid water in the water storage chamber 13. The heating medium after heat exchange can continue to circulate in the heating flow path 3 from the outlet hole to absorb heat again. At the same time, the liquid water after absorbing heat can be discharged from the drain port 133, thereby avoiding the problem that the liquid water remaining in the water storage chamber 13 freezes and blocks the drain port 133 in a low temperature environment, resulting in the water storage chamber 13 being unable to continue to discharge liquid.

[0053] In some embodiments, the gas-liquid separator 1 is provided with a gas inlet 15 and a gas outlet 16, and the gas inlet 15 and the gas outlet 166 are connected through a gas-liquid separation chamber 12, and a gas-liquid separation baffle 121 is also provided in the gas-liquid separation chamber 12, and the gas-liquid separation baffle 121 is located between the gas inlet 15 and the gas outlet 16.

[0054] That is, the gas-liquid separator 1 can be set as a baffle type, and the gas-liquid mixture can enter the gas-liquid separation chamber 12 through the gas inlet 15. The gas-liquid separation baffle 121 in the gas-liquid separation chamber 12 is mainly used to separate gas and liquid. Figure 2 As shown, a plurality of gas-liquid separation baffles 121 are provided in the gas-liquid separation chamber 12. When the gas-liquid mixture enters the gas-liquid separation chamber 12, it begins to partially separate under the action of gravity and reduced flow rate. When it contacts the gas-liquid separation baffle 121, the gas-liquid separation baffle 121 further promotes further separation of liquid and gas by changing the flow direction and speed of the gas-liquid mixture, so that the separated gas can continue to flow upward and flow out from the gas outlet 16, and the separated liquid flows downward to the water storage chamber 13 and is discharged from the drain outlet 133.

[0055] Among them, the gas-liquid separation baffle 121 is arranged between the gas inlet 15 and the gas outlet 16, which can further enhance the gas-liquid separation effect and ensure that the gas is free of the mixed liquid as much as possible when leaving the gas-liquid separation chamber 12, so that the liquid flows downward along the baffle or the inner wall of the gas-liquid separation chamber 12 and gathers in the water storage chamber 13.

[0056] The utility model also provides a muffler assembly 101.

[0057] According to the muffler assembly 101 of the embodiment of the utility model, it includes a muffler 61, an exhaust pipe 62 and a gas-liquid separation device 102 of any of the above-mentioned embodiments, the gas-liquid separator 1 is provided with a gas outlet 16, the gas outlet 16 is connected to the gas-liquid separation chamber 12, the exhaust pipe 62 is connected to the gas outlet 16, the muffler 61 is sleeved outside the exhaust pipe 62, and the exhaust pipe 62 is provided with a silencing hole connected to the inner cavity of the muffler 61.

[0058] Specifically, Figure 2 As shown, the muffler assembly 101 includes a muffler 61, an exhaust pipe 62 and a gas-liquid separation device 102, wherein the muffler 61 can be constructed in a circular tube shape with an inner cavity formed therein, and the shape and size of the exhaust pipe 62 are adapted so that it can be mounted outside the exhaust pipe 62, and the exhaust pipe 62 is provided with a silencer hole connected to the inner cavity of the muffler 61, that is, when the gas flows through the exhaust pipe to generate noise, the silencer hole can disperse and absorb the noise, and at the same time, the noise sound waves can enter the inner cavity of the muffler 61 through the silencer hole to form a resonance cavity, further dispersing and absorbing the noise sound waves, thereby reducing or eliminating the noise generated by the gas through the muffler 61.

[0059] Therefore, the gas after gas-liquid separation in the gas-liquid separator 1 can flow out from the gas outlet 16 and smoothly enter the exhaust pipe 62. Through the silencing hole connected to the inner cavity of the muffler 61, a resonance cavity is formed to silence the exhaust gas flow, reduce the noise generation, and effectively improve the reliability and operation stability of the muffler assembly 101.

[0060] The utility model also provides a fuel cell system 100 .

[0061] According to an embodiment of the utility model, the fuel cell system 100 includes an air filter 71, an air compressor 72, an intercooler 73, a humidifier 74, a fuel cell 75 and a muffler assembly 101 of any of the above embodiments, and the air filter 71, the air compressor 72, the intercooler 73, the humidifier 74, the fuel cell 75 and the muffler assembly 101 are connected in sequence.

[0062] Specifically, Figure 1As shown, the air filter 71, the air compressor 72, the intercooler 73, the humidifier 74, the fuel cell 75 and the muffler assembly 101 are connected in sequence. The air filter 71 is the entrance of the fuel cell system 100, connected to the outside air, and is used to remove dust, particles and moisture in the air to ensure that the air entering the fuel cell system 100 is clean. The cleaned air filtered by the air filter 71 enters the air compressor 72 and is compressed. The air is pressurized to meet the requirements of the fuel cell system 100. After that, the compressed air comes out of the air compressor 72 and enters the intercooler 73. The intercooler 73 cools down the temperature of the high-temperature and high-pressure air output by the air compressor 72 to increase the air density, thereby increasing the air intake and efficiency of the fuel cell 75. The air cooled in the intercooler 73 is then transported to the humidifier 74. The humidifier 74 humidifies the air cooled by the intercooler 73 to increase the humidity of the air, thereby improving the operating efficiency of the fuel cell 75. Finally, the humidified air is transported to the fuel cell 75. In the fuel cell 75, the humidified hydrogen and the oxygen in the air undergo an electrochemical reaction to generate electricity and a gas-liquid mixture consisting of exhaust gas and water.

[0063] After the gas-liquid mixture comes out of the fuel cell 75, it enters the muffler assembly 101, and the gas and liquid are separated by the gas-liquid separation device 102. The separated gas is discharged into the outside atmosphere after being subjected to noise reduction treatment through the exhaust pipe 62 and the muffler 61.

[0064] Thus, the air filter 71, the air compressor 72, the intercooler 73, the humidifier 74, the fuel cell 75 and the muffler assembly 101 are connected in sequence to form a complete air supply and exhaust gas emission circuit, which can ensure the efficient and stable operation of the fuel cell system 100.

[0065] The utility model also provides a vehicle.

[0066] According to the vehicle of the embodiment of the utility model, a fuel cell system 100 of any of the above embodiments is provided. In the fuel cell system 100, by providing a connected heating flow path 3 and a heating chamber 14, the heat generated by the braking of the brake module 2 can be transported to the heating flow path 3, and the braking heat is transmitted to the heating chamber 14 by the heating medium in the heating flow path 3, and heat exchange with liquid water in the heating chamber 14 is performed to achieve continuous heating of the water storage chamber 13, thereby achieving effective recovery and reuse of the braking heat, ensuring that the liquid water separated in the water storage chamber 13 can be continuously discharged to the outside of the vehicle, effectively avoiding the occurrence of the problem of pipeline icing due to the failure of condensed water to be discharged outside the vehicle in time, thereby improving the reliability and operation stability of the vehicle and ensuring the normal operation of the vehicle.
