Description

Technical Field

[0001] This utility model relates to the field of automotive fuel cell technology, and in particular to an integrated intercooler and throttle humidifier. Background Technology

[0002] Hydrogen fuel cells, as a highly efficient and clean energy conversion device, are attracting increasing attention in the automotive field. Their core component, the proton exchange membrane (PEM), requires suitable humidity conditions to maintain good proton conductivity. When the PEM is too dry, its proton conductivity drops sharply, leading to increased internal resistance and reduced output power. Conversely, excessive moisture can cause flooding, hindering gas diffusion and similarly reducing battery performance. Therefore, precisely controlling the humidity of the reactant gases entering the hydrogen fuel cell is crucial. The intercooler works by using heat exchange between air and coolant to cool the high-temperature pressurized air, increasing air density and engine intake, thereby improving engine power and torque.

[0003] The existing design of intercoolers, throttle valves, and humidifiers in fuel cell stacks, which operate independently, has many shortcomings and cannot meet the demands of modern automotive engines for efficient, compact, and intelligent intake systems. Developing a novel device that integrates an intercooler and a throttle valve humidifier to achieve coordinated control of intake air temperature and humidity, optimize engine compartment layout, and improve the overall performance of the intake system has significant practical implications and market demand.

[0004] According to Chinese Publication No. CN113270615A, an air humidifier and a fuel cell vehicle are disclosed. The air humidifier includes a humidifier housing, a humidification regulator, a humidification component, and a dry gas passage disposed within the humidifier housing. The humidifier housing has a dry gas inlet, a dry gas outlet, a humidified gas inlet, and a humidified gas outlet. The humidification regulator is connected to the dry gas inlet, the humidification component, and the dry gas passage, and is used to divert dry gas input from the dry gas inlet to the humidification component and the dry gas passage. One end of the dry gas passage is connected to the humidification regulator, and the other end is connected to the dry gas outlet. The humidification component is connected to the humidified gas inlet, the humidified gas outlet, the humidification regulator, and the dry gas outlet, and uses the humidified gas input from the humidified gas inlet to humidify the dry gas output from the humidification regulator, so that the humidified gas is output to the dry gas outlet. The air humidifier provided by this invention is used to regulate the humidity of the gas entering the fuel cell.

[0005] The aforementioned patent documents and prior art have the following technical problems:

[0006] 1. In the existing technology, the intercooler, humidifier and throttle body are usually designed separately, installed independently and connected by a complex piping system. This design results in the whole device occupying a large space, which is difficult to adapt to the limited layout space inside the vehicle. The space utilization rate is low. The separate design requires additional piping and connecting parts, which increases the overall weight and maintenance difficulty, which is not conducive to the vehicle's lightweight requirements.

[0007] 2. In the existing technology, the humidifier usually adopts a fixed mode for the humidification process of dry gas, and lacks a dynamic control mechanism for humidity and flow rate. This makes it difficult to adjust the humidification effect according to the real-time needs of the hydrogen fuel cell stack. If the flow rates of wet and dry gas cannot be flexibly adjusted, it may also lead to gas waste or unstable system operation. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies, such as large space occupation, heavy weight, and lack of precise control over gas humidity and flow rate, by proposing an integrated intercooler and throttle body humidifier.

[0009] To achieve the above objectives, this utility model adopts the following technical solution: an integrated intercooler and throttle-valve humidifier, comprising an intercooler unit, a humidifier unit, and a gas intelligent control system. The intercooler unit includes an intercooler, a coolant inlet, a coolant outlet, and a cooling dry gas inlet. The humidifier unit includes a humidifier, a humidified dry gas inlet, a dry gas outlet, a humid gas inlet, and a humid gas outlet. The gas intelligent control system includes a throttle valve. The intercooler and humidifier are connected via flanges. The throttle valve is located at the humidifier's humidifier inlet and dry gas outlet. The cooling dry gas inlet is located at the top of the intercooler and is connected to an external compressed air circuit via a pipeline. The humidified dry gas inlet is located at the top of the humidifier and is connected to the cooling dry gas inlet via the intercooler. The dry gas outlet is located at the end of the humidifier furthest from the intercooler and is connected to an external hydrogen fuel cell stack via a pipeline.

[0010] Preferably, a sealing ring is provided at the flange connection between the intercooler and the humidifier.

[0011] Preferably, the throttle valve includes a first throttle valve and a second throttle valve, with the first throttle valve located at the moisture inlet of the humidifier and the second throttle valve located at the dry air outlet of the humidifier.

[0012] Preferably, the coolant inlet is located on one side of the intercooler, and the coolant outlet is located on the other side of the intercooler. The coolant inlet and coolant outlet are respectively connected to an external coolant circulation system through pipelines, and the coolant inlet and coolant outlet are respectively located on opposite sides of the intercooler.

[0013] Preferably, the bottom of the intercooler and the edge of the humidifier are provided with fixed feet, and the fixed feet include at least two, which are respectively provided at both ends of the bottom of the intercooler and the humidifier.

[0014] Preferably, the humidifying dry air inlet is located on the top of the humidifier near the intercooler, and the dry air outlet is located on the bottom of the humidifier away from the intercooler.

[0015] Preferably, the moisture inlet is located at one end of the top of the humidifier and is connected to an external hydrogen fuel cell stack via a pipeline, and the moisture outlet is located at the other end of the top of the humidifier and is connected to an external gas path via a pipeline.

[0016] Beneficial effects

[0017] In this invention, the intercooler, humidifier, and throttle valve are integrated into a single device, using direct flange connections and eliminating the need for additional gas piping in traditional designs, significantly optimizing the overall structural compactness. This integrated design not only reduces the device's size, allowing for more efficient layout within limited vehicle interior space, but also lowers the overall weight, facilitating installation and maintenance. The fixed support feet further enhance the device's stability, ensuring its reliability during operation. Compared to traditional split designs, it effectively reduces the complexity and installation difficulty associated with piping connections, facilitating the overall integration of fuel cell systems and contributing to improved vehicle space utilization and weight reduction.

[0018] In this invention, a first throttle valve and a second throttle valve are installed at the wet gas inlet and dry gas outlet of the humidifier. A gas intelligent control system dynamically adjusts the gas flow rate, enabling precise control of the intake humidity and flow rate according to the real-time requirements of the hydrogen fuel cell stack. The rational layout of the throttle valves at the wet gas inlet and dry gas outlet, combined with membrane structure humidification technology, ensures the high efficiency and stability of the gas during the humidification process. The intelligent control mechanism allows the device to flexibly adapt to the operating requirements under different conditions, reducing gas waste and optimizing the reaction conditions of the fuel cell stack, thus providing a reliable guarantee for the efficient operation of the fuel cell system.

[0029] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0030] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0032] Reference Figures 1 to 8 An integrated intercooler and throttle body humidifier, comprising an intercooler unit, a humidifier unit, and a gas intelligent control system, specifically including the following:

[0033] The intercooler unit includes an intercooler 7, a coolant inlet 8, a coolant outlet 9, and a cooling dry air inlet 11. The coolant inlet 8 is located on the side of the intercooler 7 closest to the humidifier 1, and the coolant outlet 9 is located on the other side of the intercooler 7 furthest from the humidifier 1. The coolant inlet 8 and coolant outlet 9 are located on opposite sides of the intercooler 7 and are connected to an external coolant circulation system via pipelines. The cooling dry air inlet 11 is located at the top of the intercooler 7 and is connected to an external compressed air path via a pipeline. The function of the intercooler unit is to regulate the temperature of the incoming compressed air through a heat exchange structure. The cooling dry air inlet 11 is located at the top of the intercooler 7, which facilitates the entry of compressed air from the top and its downward flow. The coolant inlet 8 and the coolant outlet 9 are located on opposite sides of the intercooler 7 to ensure that the coolant can flow evenly through the heat exchange area. The coolant enters from the external coolant circulation system, carries away the heat of the compressed air through the heat exchange channel, and then flows out. This structural design makes the heat exchange process more efficient. At the same time, the layout of the coolant inlet 8 being close to the humidifier 1 and the coolant outlet 9 being far away from the humidifier 1 is conducive to the formation of counter-current heat exchange between the coolant flow direction and the compressed air flow direction, thereby improving the heat exchange efficiency. The function of the humidifier 1 unit is to humidify the dry air through the membrane structure.

[0034] The humidifier unit 1 includes a humidifier 1, a humidifying dry gas inlet 2, a dry gas outlet 3, a moisture inlet 4, and a moisture outlet 5. The humidifying dry gas inlet 2 is located on the top of the humidifier 1 near the intercooler 7, and is connected to the cooling dry gas inlet 11 via the intercooler 7. The dry gas outlet 3 is located on the bottom of the humidifier 1 away from the intercooler 7, and is connected to an external hydrogen fuel cell stack via a pipeline. The moisture inlet 4 is located at one end of the top of the humidifier 1, and is connected to an external hydrogen fuel cell stack via a pipeline. The moisture outlet 5 is located on the bottom of the humidifier 1 near the intercooler 7. The humidifier 1 is placed at the top of the other end, and the moisture outlet 5 is connected to the external air passage through the pipeline. The humidifying dry air inlet 2 is located on the top of the humidifier 1 near the intercooler 7, ensuring that the compressed air flowing out from the intercooler 7 can directly enter the dry side channel. The moisture inlet 4 and the moisture outlet 5 are located at the top of the humidifier 1 at both ends, forming a smooth moisture flow path. The moisture permeates into the dry side channel through the membrane. The dry air outlet 3 is located at the bottom of the humidifier 1 away from the intercooler 7, so that the humidified air can flow out smoothly. This layout optimizes the gas flow path and reduces flow resistance.

[0035] The intelligent gas control system includes a throttle valve 6, which comprises a first throttle valve and a second throttle valve. The first throttle valve is located at the moisture inlet 4 of the humidifier 1, and the second throttle valve is located at the dry gas outlet 3 of the humidifier 1. The intelligent gas control system achieves precise regulation of gas flow through the throttle valve 6. The first throttle valve and the second throttle valve are located at the moisture inlet 4 and the dry gas outlet 3, respectively. By adjusting the opening and closing degree, the flow rates of moisture and dry gas can be dynamically controlled, thereby affecting the humidification effect. This design allows the device to flexibly adjust the gas state according to actual needs.

[0036] Intercooler 7 and humidifier 1 are connected by a flange, and a sealing ring is provided at the flange connection between intercooler 7 and humidifier 1. The direct connection between intercooler 7 and humidifier 1 via flange and the provision of a sealing ring reduces the use of gas pipelines, lowers the risk of gas leakage, and simplifies the structure. Fixed supports 10 are provided at the bottom of intercooler 7 and the edge of humidifier 1. There are at least two fixed supports 10, which are respectively set at both ends of the bottom of intercooler 7 and humidifier 1. The fixed supports 10 provide stable support and ensure the stability of the device during operation. The overall integrated design integrates the intercooler, humidifier 1 and throttle valve into one device, reducing space occupation and weight. At the same time, it optimizes the gas flow path and reduces pressure loss caused by pipeline bends. The introduction of the throttle valve enables automated control of the gas humidification process. The overall device has a clear operating logic, a compact structure, and high integration and practicality.

[0037] The overall operation plan, process, and workflow of the device are as follows: External compressed air first enters the intercooler 7 through the pipeline via the cooling dry air inlet 11 at the top, and then enters the intercooler 7. The intercooler 7 exchanges heat with the external coolant circulation system through its internal heat exchange structure. Coolant enters the intercooler 7 through the coolant inlet 8, flows through the heat exchange channels inside the intercooler 7, and then flows out through the coolant outlet 9. The coolant inlet 8 and the coolant outlet 9 are located on opposite sides of the intercooler 7 to ensure that the coolant can flow evenly through the heat exchange area inside the intercooler 7. The cooling dry air inlet 11 is located at the top of the intercooler 7, facilitating the entry of compressed air from the top and its downward flow. After heating, the temperature of the compressed air decreases, and it then flows out from the intercooler 7, directly entering the humidifying dry air inlet 2 at the top of the humidifier 1 via a flange connection. The intercooler 7 and the humidifier 1 are connected by a flange, and a sealing ring is installed at the connection. This direct connection method reduces additional gas pipelines and simplifies the complexity of the gas flow path. At the same time, the presence of the sealing ring effectively prevents gas leakage at the connection. The humidifying dry air inlet 2 is located on the top of the humidifier 1 near the intercooler 7, allowing the compressed air flowing out from the intercooler 7 to smoothly enter the dry side channel of the humidifier 1. Inside the humidifier 1, the dry side channel and the wet side channel are separated by a membrane structure. Moisture inlet 4... Located at one end of the top of the humidifier 1, it is connected to an external hydrogen fuel cell stack via a pipeline. Water vapor generated by the reaction in the hydrogen fuel cell stack enters the wet-side channel of the humidifier 1 through the moisture inlet 4. The moisture outlet 5 is located at the other end of the top of the humidifier 1 and is connected to an external air passage via a pipeline. When the moisture flows in the wet-side channel, the water vapor permeates through a membrane into the dry-side channel, humidifying the compressed air in the dry-side channel. The moisture inlet 4 and moisture outlet 5 are located at both ends of the top of the humidifier 1 to ensure that moisture can enter from one end and flow out from the other, forming a smooth moisture flow path. Simultaneously, the first throttle valve in the throttle valve 6 is located at the moisture inlet 4, and the second... The throttle valve is located at the dry gas outlet 3. By adjusting the opening degree of the first throttle valve, the flow rate of humid air entering the wet side channel can be controlled. By adjusting the opening degree of the second throttle valve, the airflow state at the outlet of the dry side channel can be controlled. The dry gas outlet 3 is located on the bottom of the humidifier 1 away from the intercooler 7. The humidified compressed air flows out from the dry gas outlet 3 and enters the external hydrogen fuel cell stack through the pipeline for its reaction. The fixed support 10 is located at the bottom of the intercooler 7 and the edge of the humidifier 1. At least two fixed support 10s are located at the two ends of the bottom of the intercooler 7 and the humidifier 1, respectively, to provide stable support and ensure the stability of the device during operation. Specific Implementation Example 2:

[0039] Reference Figures 1 to 8 Based on the content of the above specific embodiments, the following content is further disclosed:

[0040] In actual use, the entire device, such as Figure 8The connection structure, Figure 8 In the diagram, 12 represents the cooling system, 12 represents the gas supply system, 14 represents the hydrogen fuel cell stack, 15 represents the control system, and 16 represents the sensors. Sensor 16 includes a temperature sensor, a humidity sensor, and a pressure sensor. Its use involves the following steps:

[0041] Step 1: Compressed air enters the intercooler unit: An external air compressor or booster system compresses air into high-temperature, high-pressure compressed air, which is then delivered through pipelines to the cooling dry air inlet 11 at the top of the intercooler 7. The cooling dry air inlet 11 is located at the top of the intercooler 7, facilitating the entry of compressed air from the top and its downward flow into the heat exchange channels inside the intercooler 7;

[0042] Step 2: Intercooler performs heat exchange and cooling: When compressed air flows inside intercooler 7, it exchanges heat with the coolant. Coolant enters intercooler 7 from the external coolant circulation system through pipes to the coolant inlet 8, located on the side of intercooler 7 closest to humidifier 1. The coolant flows through the heat exchange channels inside intercooler 7, absorbing heat from the compressed air, and then flows out from the coolant outlet 9, located on the other side of intercooler 7 furthest from humidifier 1. The coolant inlet 8 and coolant outlet 9 are positioned on opposite sides, forming a counter-current heat exchange mode to improve heat exchange efficiency. After heat exchange, the coolant flows back to the external coolant circulation system through pipes, while the temperature of the compressed air decreases, becoming cooled dry air.

[0043] Step 3: Cooled dry air enters humidifier unit 1: The cooled compressed air flows out from the intercooler 7 and directly enters the humidifying dry air inlet 2 at the top of humidifier 1 through the flange connection between the intercooler 7 and humidifier 1. The humidifying dry air inlet 2 is located on the top of humidifier 1 near the intercooler 7, ensuring smooth gas flow into the dry side channel of humidifier 1. A sealing ring is installed at the flange connection to prevent gas leakage, and the direct connection method reduces additional gas piping and lowers flow resistance.

[0044] Step 4: Moisture enters the wet side channel of humidifier 1: Simultaneously, during operation, the hydrogen fuel cell stack generates water vapor through an electrochemical reaction. This water vapor is transported from the stack's exhaust port to the moisture inlet 4 of humidifier 1 via a pipeline. Moisture inlet 4 is located at the top end of humidifier 1, allowing moisture to enter the wet side channel. The wet side channel is separated from the dry side channel by a membrane structure. As water vapor flows within the wet side channel, it permeates through the membrane into the dry side channel.

[0045] Step 5: Humidifier 1 humidifies the dry air: Inside humidifier 1, the cooled dry air in the dry-side channel exchanges moisture with the water vapor in the wet-side channel through a membrane. The water vapor permeates into the dry-side channel, gradually humidifying the dry air. The moisture inlet 4 and moisture outlet 5 are located at the top two ends of humidifier 1, respectively. Moisture enters from one end, flows through the wet-side channel, and exits from the moisture outlet 5. The moisture outlet 5 is connected to the external exhaust system through a pipe to discharge any remaining moisture. During the humidification process, the dry air gradually becomes humidified air.

[0046] Step 6: Throttle Valve Adjustment of Gas Flow: A first throttle valve is installed at the wet gas inlet 4 of the humidifier 1, and a second throttle valve is installed at the dry gas outlet 3. The first throttle valve controls the flow rate of wet gas entering the wet side channel by adjusting its opening degree, thus affecting the humidification effect; the second throttle valve controls the airflow state at the outlet of the dry side channel by adjusting its opening degree, thereby regulating the output flow rate of the humidified air. The throttle valve 6 is controlled by the intelligent gas control system. The system dynamically adjusts the opening degree of the throttle valve based on sensor feedback such as humidity, temperature, and pressure to ensure that the humidity and flow rate of the output gas meet the requirements of the hydrogen fuel cell stack.

[0047] Step 7: Humidified air enters the hydrogen fuel cell stack: The humidified air flows out from the dry gas outlet 3 of the humidifier 1. The dry gas outlet 3 is located at the bottom of the humidifier 1 on the side away from the intercooler 7, and is transported to the air inlet of the external hydrogen fuel cell stack through pipelines. After entering the stack, the humidified air participates in the electrochemical reaction as a reactant, generating electrical energy and water vapor.

[0048] Step 8: Cyclic Operation and Device Support: The water vapor generated by the hydrogen fuel cell stack reaction continues to enter the moisture inlet 4 through the pipeline, forming a moisture circulation; compressed air and coolant also continuously enter the device from the external system, forming a continuous operating cycle. Fixed feet 10 are set at the bottom of the intercooler 7 and the edge of the humidifier 1, with at least two fixed feet 10 located at both ends, and fixed to the base of the vehicle or equipment by bolts to ensure the stability of the device during operation.

[0049] In summary:

[0050] 1. The intercooler, humidifier 1, and throttle valve are integrated into a single unit using a flange connection, eliminating the need for additional gas piping in traditional designs and significantly optimizing the overall structural compactness. This integrated design not only reduces the unit's size, allowing for more efficient layout within limited vehicle interior space, but also lowers the overall weight, facilitating installation and maintenance. The fixed support feet further enhance the unit's stability, ensuring its reliability during operation. Compared to traditional split designs, it effectively reduces the complexity and installation difficulty associated with piping connections, facilitating the overall integration of the fuel cell system and contributing to improved vehicle space utilization and weight reduction.

[0051] 2. A first and second throttle valve are installed at the wet gas inlet and dry gas outlet of humidifier 1. A gas intelligent control system dynamically adjusts the gas flow rate, precisely controlling the humidity and flow rate of the incoming gas according to the real-time requirements of the hydrogen fuel cell stack. The rational layout of the throttle valves at the wet gas inlet and dry gas outlet, combined with membrane structure humidification technology, ensures the high efficiency and stability of the gas during the humidification process. The intelligent control mechanism allows the device to flexibly adapt to the operating requirements under different conditions, reducing gas waste and optimizing the reaction conditions of the fuel cell stack, providing a reliable guarantee for the efficient operation of the fuel cell system.
