Description

Technical Field

[0001] This disclosure relates to refrigeration devices, and more particularly to an intercooler cooling mechanism and an intercooler and fuel cell system. Background Technology

[0002] With the increasing adoption of fuel cells, their performance is receiving more and more attention. Fuel cell stacks require appropriate air temperatures to achieve optimal operating performance. Excessively high or low inlet air temperatures can degrade fuel cell stack performance and even severely impact its lifespan. Currently, to address the issue of inlet air temperature in fuel cells, an intercooler is added between the air compressor and the fuel cell stack. This intercooler has both gas and coolant inlets and outlets, with cooling channels positioned above the gas channels. When the fuel cell engine is operating, the high-temperature airflow generated by the front-end air compressor passes through the intercooler and is cooled by the coolant within the intercooler's cooling channels, thus achieving temperature reduction and ensuring the appropriate inlet air temperature for the fuel cell stack.

[0003] The existing intercoolers have the following problems when in use:

[0004] Existing intercooler structures are all mechanical components; once designed, the gas and cooling channels remain unchanged, resulting in fixed cooling performance. However, due to the varying required air temperature entering the fuel cell stack under different environments after prolonged operation, the intercooler's cooling channels may experience insufficient or excessive heat dissipation during operation. This could negatively impact the fuel cell stack's inlet air temperature and the fuel cell engine's efficiency.

[0005] In view of this, it is necessary to design a new type of intercooler cooling mechanism that can overcome the above-mentioned technical difficulties and effectively solve or alleviate them. Utility Model Content

[0008] Furthermore, the technical problem to be solved by this disclosure is to provide a fuel cell system that can meet the heat dissipation requirements under different conditions, ensure the intake temperature of the fuel cell stack, improve the working efficiency and increase the service life of the fuel cell engine, and at the same time realize intelligent control of the flow rate of the cooling medium in the cooling channel to save energy.

[0010] An adjustment device is installed on the inlet channel of the cooling channel to adjust the flow rate of the cooling medium entering the cooling channel.

[0011] In some embodiments, a receiving cavity is formed within the inflow channel, and the cross-sectional area of ​​the receiving cavity is larger than the cross-sectional area of ​​the inflow end of the inflow channel.

[0012] In some embodiments, the adjustment device includes an adjustment member and a drive member. The adjustment member is adjustablely mounted inside the receiving cavity by the drive member.

The spherical adjusting member is driven by the driving member to solve the overlapping area of ​​the cross-section of the flow channel and the cross-section of the receiving cavity.

[0016] In some embodiments, a filter element is also provided inside the inflow channel, and the filter chamber can filter the cooling medium flowing into the cooling channel.

The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure. This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0028] These embodiments are provided to make the disclosure thorough and complete, and to fully express the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, material composition, numerical expressions, and values ​​set forth in these embodiments should be interpreted as exemplary only and not as limiting.

[0030] Furthermore, the term "parallel" as used in this disclosure is not parallel in the strict sense, but rather within the permissible range of error. Words such as "including" or "contains" mean that the element preceding the word covers the element listed after the word, without excluding the possibility that it may also cover other elements.

[0031] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0032] All terms used in this disclosure have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0034] like Figures 1 to 3 As shown, the intercooler cooling mechanism provided in this disclosure includes a cooling channel 1 and an adjusting device 2. Cooling medium is introduced into the cooling channel 1 through the inlet channel 11 and flows out from the outlet of the cooling channel 1, allowing the cooling medium to circulate in the cooling channel 1. The adjusting device 2 is installed on the inlet channel 11 of the cooling channel 1 and adjusts the flow rate of the cooling medium in the cooling channel 1 to control the flow rate of the cooling medium in the cooling channel 1, so as to adapt to different heat dissipation requirements, avoid excessive heat dissipation performance, and improve working efficiency.

[0035] In some embodiments, such as Figure 1 As shown, in some embodiments, a receiving cavity 3 is formed within the inflow channel 11, and the cross-sectional area of ​​the receiving cavity 3 is larger than the cross-sectional area of ​​the inflow end of the inflow channel 11, wherein, as shown in the attached figure... Figure 1 As shown, the cross-sections of the inlet channel 11 and the receiving cavity 3 are perpendicular to the flow direction of the cooling medium. An adjustment device 2 can be installed in the receiving cavity 3. The cross-sectional area of ​​the receiving cavity 3 is larger than the cross-sectional area of ​​the inlet end of the inlet channel 11, so that the adjustment device 2 reduces the impact on the flow rate of the cooling medium in the inlet channel 11 when it does not adjust the flow rate of the cooling medium.

[0036] In some embodiments, such as Figure 1 As shown, the regulating device 2 includes an regulating component 21 and a driving component. The regulating component 21 is adjustablely installed inside the receiving cavity 3 via the driving component 22. For example, the driving component 22 can drive the regulating component to rotate, extend, or retract. The cross-section of the receiving cavity 3 is parallel to the cross-section of the cooling channel 1. Thus, the driving component 22 can control the regulating component 21 to change the shading area of ​​the cross-section of the receiving cavity 3, thereby achieving the purpose of regulating the flow rate of the cooling medium in the cooling channel 1. This realizes the control of the flow rate of the cooling medium in the cooling channel 1. Depending on the different temperature requirements of the equipment to be cooled, the driving component 22 manipulates the regulating component 21 to change the shading area of ​​the cross-section of the receiving cavity 3, so that the shading area reaches a specified size, thereby enabling the cooling medium in the cooling channel 1 to reach a specified flow rate. The equipment that needs to be cooled is cooled to the required temperature by the cooling channel 1, thereby adapting to different heat dissipation needs, avoiding excessive heat dissipation performance, and improving working efficiency.

[0037] In some embodiments, Figure 1As one embodiment of this disclosure, the adjusting member 21 can be a valve plate, and the driving member 22 can be a valve motor. The valve motor can be a 24V low-voltage motor or a 12V low-voltage motor. One side of the valve plate is rotatably mounted on the inner wall of the receiving cavity 3, so that the valve motor can drive the valve plate to rotate within the receiving cavity 3 about the side connected to the inner wall of the receiving cavity 3 as an axis. This controls the valve plate to change the shading area of ​​the cross-section of the receiving cavity 3, thereby changing the portion of the receiving cavity 3 through which the cooling medium can pass, adjusting the flow rate of the cooling medium in the cooling channel 1. When the equipment requiring cooling has different cooling requirements... When the valve plate is rotated to a specified position by the valve motor, the flow rate of the cooling medium in the receiving cavity 3 reaches the amount required by the equipment that needs to be cooled, thereby cooling the equipment to a specified temperature. This adapts to different heat dissipation needs, avoids excessive heat dissipation performance, and improves work efficiency. When the valve plate is rotated to the maximum extent by the valve motor, the outer circumference of the valve plate fits against the inner wall of the receiving cavity 3, completely sealing the receiving cavity 3. When the valve plate is rotated to the minimum extent by the valve motor, the valve plate rotates to the maximum extent towards the side connected to the receiving cavity 3, and there is a certain angle on the side connected to the receiving cavity 3.

[0038] In some embodiments, the adjusting member 21 can be an adjusting plate, which is rotatably mounted inside the receiving cavity 3 via a rotating shaft. The rotating shaft can be located in the middle of the adjusting plate. The driving member 22 can be a rotating motor, which drives the rotating shaft to rotate, thereby driving the adjusting plate to rotate around the rotating shaft. The axis of the rotating shaft is perpendicular to the axis of the inflow channel 11, that is, the adjusting plate is vertically mounted inside the receiving cavity 3. The rotating motor rotates the angle of the adjusting plate inside the receiving cavity 3, where the angle is the angle between the surface of the adjusting plate and the cross-section of the receiving cavity 3, with its vertex located on the rotating shaft. This allows the portion of the space between the two sides of the adjusting plate and the inner wall of the receiving cavity 3 that can be cooled by the medium to be changed, thereby changing the flow rate of the cooling medium in the receiving cavity 3 to adapt to different heat dissipation requirements, avoid excessive heat dissipation performance, and improve working efficiency. The rotating motor can drive the adjusting plate to rotate so that the adjusting plate is perpendicular to the cross-section of the receiving cavity 3, that is, the angle between the surface of the adjusting plate and the cross-section of the receiving cavity 3 is 90°. At this time, the maximum flow rate of the cooling medium in the receiving cavity 3 can be maximized, avoiding the adjusting member 21 from significantly reducing the maximum flow rate of the cooling medium in the receiving cavity 3, which would lead to a decrease in heat dissipation performance.

[0039] In some embodiments, the adjusting member 21 is a spherical adjusting member, which can be rotatably mounted inside the receiving cavity 3 via the driving member 22. A flow channel is provided through the spherical adjusting member. The spherical adjusting member is driven by the driving member 22 to change the overlapping area of ​​the cross-section of the flow channel with the cross-section of the receiving cavity 3. That is, by rotating the spherical adjusting member inside the receiving cavity 3, the direction of the flow channel in the receiving cavity 3 is adjusted. Adjusting the size of the channel through which the cooling medium can pass in the receiving cavity 3 changes the flow rate of the cooling medium in the cooling flow channel 1. The cross-section of the flow channel on the spherical adjusting member can overlap with the cross-section of the receiving cavity 3. The cross-sections of the two sections are parallel, which maximizes the flow rate of the cooling medium in the cooling channel 1. This avoids the problem of the regulating component 21 reducing the maximum flow rate in the cooling channel 1 and reducing the maximum cooling effect. When the equipment that needs heat dissipation has different heat dissipation requirements, the spherical regulating component can be driven by the driving component 22 to change the overlapping area of ​​the cross-section of the channel and the cross-section of the receiving cavity 3, so that the overlapping area reaches the required size. This allows the cooling medium in the receiving cavity 3 to reach the specified flow rate, so that the equipment that needs heat dissipation can reach the required temperature, in order to adapt to different heat dissipation requirements, avoid excessive heat dissipation performance, and improve the working efficiency of the intercooler.

[0040] In some embodiments, a filter element is also provided inside the inflow channel 11. The filter element can filter the cooling medium flowing into the cooling channel 1. The filter element can be a mesh filter or the like installed inside the cooling channel 1 to filter impurities in the cooling medium, prevent impurities from damaging the equipment, and increase the service life of the equipment.

[0041] Based on the technical solution of the intercooler cooling mechanism disclosed above, such as Figure 2 As shown, this disclosure also provides an intercooler, which includes a gas flow channel 4 and an intercooler cooling mechanism provided in some of the above specific embodiments. The gas flow channel 4 can be arranged above the cooling flow channel 1 in the intercooler, so that the cooling medium flowing inside the cooling flow channel 1 in the intercooler cooling mechanism can cool the gas flowing inside the gas flow channel 4. The equipment that needs to be cooled has different temperature requirements for the gas in the gas flow channel 4. The flow rate of the cooling medium in the cooling flow channel 1 can be adjusted by the adjusting device 2 so that the cooling flow channel 1 cools the gas in the gas flow channel 4 to the temperature required by the equipment that needs to be cooled, so as to adapt to different heat dissipation requirements and avoid excessive heat dissipation performance.

[0042] Based on the above-disclosed technical solution for the intercooler, as follows: Figure 2 and Figure 3As shown, this disclosure also provides a fuel cell system, which includes an air compressor, a fuel cell engine, and an intercooler according to the above technical solution. The intercooler is disposed between the air compressor and the fuel cell engine. The air outlet of the air compressor is connected to the inlet of the gas flow channel 4 of the intercooler, and the outlet of the gas flow channel 4 is connected to the inlet of the fuel cell engine. When the fuel cell engine is working, the high-temperature gas generated by the air compressor flows into the fuel cell engine through the gas flow channel 4, providing air at an appropriate temperature to the fuel cell stack inside the fuel cell engine. The high-temperature gas flowing into the gas flow channel 4 is cooled by the cooling medium in the cooling channel 1, thereby regulating the temperature of the high-temperature gas in the gas flow channel 4 to reach a specified temperature, improving the working performance of the fuel cell stack and increasing its service life. At the same time, according to the different temperature requirements of the fuel cell engine, the flow rate of the cooling medium in the cooling channel 1 is adjusted by the regulating device 2 to perform targeted cooling of the high-temperature gas in the gas flow channel 4, so as to adapt to different heat dissipation requirements, avoid excessive heat dissipation performance, and improve the working efficiency of the intercooler.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, the fuel cell engine is equipped with an engine controller and a temperature sensor 5. The temperature sensor 5 is connected to the engine controller and the regulating device 2 in the intercooler. The temperature sensor 5 and the regulating device 2 in the intercooler can be wirelessly connected. The operating states of the cooling flow rate, the drive unit 22, and the regulating device 21 are calibrated in advance under different operating conditions to ensure consistency between the cooling medium flow rate and the regulating device 21. The temperature sensor 5 senses the actual intake air temperature of the fuel cell engine and transmits the sensed actual intake air temperature to the engine controller. The engine controller sets the target intake air temperature for the fuel cell engine. The difference between the actual intake air temperature sensed by temperature sensor 5 and the actual intake air temperature is calculated to obtain the required target cooling flow rate. Then, the drive component 22 in the regulating device 2 of the intercooler is controlled to drive the regulating component 21 to rotate. The regulating component 21 adjusts the shielding area of ​​the cross-section of the receiving cavity 3, thereby regulating the flow rate of the cooling medium in the cooling channel 1. This controls the air temperature in the gas channel 4, so that the high temperature air temperature in the gas channel 4 reaches the optimal temperature of the fuel cell stack, improving the working performance of the fuel cell stack and increasing its service life. At the same time, the flow rate of the cooling medium in the cooling channel 1 is intelligently controlled to adapt to the heat dissipation requirements of different fuel cell stacks, thereby improving the working efficiency of the fuel cell engine.

[0044] To facilitate a deeper understanding of the technical concept and advantages of the intercooler cooling mechanism disclosed herein, the following is combined with... Figures 1 to 3 The present disclosure describes the structural form of the intercooler cooling mechanism, which has relatively preferred features and is relatively comprehensive.

[0045] The intercooler cooling mechanism is located inside the intercooler. The intercooler cooling mechanism includes a cooling channel 1 for the flow of cooling medium and a regulating device 2 for adjusting the flow rate of the cooling medium within the cooling channel 1. The intercooler also includes a gas channel 4. The cooling channel 1 cools the gas channel 4. The inlet end of the gas channel 4 is connected to the air outlet of the air compressor, and the outlet end of the gas channel 4 is connected to the fuel cell engine. This allows the high-temperature gas generated by the air compressor to be cooled by the cooling channel 1 and then enter the fuel cell engine through the gas channel 4. One end of the cooling channel 1 is an inlet channel 11, within which a receiving cavity 3 and a filter are provided. The filter filters the cooling medium to prevent impurities from damaging the intercooler and the fuel cell engine. The receiving cavity 3 is perpendicular to the cooling medium. The cross-sectional area of ​​the direction is larger than the cross-sectional area of ​​the inlet end of the inlet channel 11, which facilitates the installation of the adjustment device 2 in the receiving cavity 3. The adjustment device 2 includes an adjustment component 21 and a drive component 22. The adjustment component 21 is adjustablely installed inside the receiving cavity 3 through the drive component 22, and the shielding area of ​​the adjustment component 21 on the cross-section of the receiving cavity 3 can be adjusted. The cross-section of the receiving cavity 3 is parallel to the cross-section of the cooling channel 1 and the receiving cavity, thereby adjusting the flow rate of the cooling medium in the receiving cavity 3. An engine controller and a temperature sensor 5 are installed on the fuel cell engine. The temperature sensor 5 is wirelessly connected to the engine controller and the drive component 22. The cooling flow rate and the working status of the drive component 22 and the adjustment component 21 are pre-programmed for different working conditions. The calibration is performed to ensure consistency between the cooling flow rate and the regulating component 21. The regulating component 21 can be a valve plate, one side of which is rotatably mounted on the inner wall of the receiving cavity 3, so that the length direction of the valve plate is perpendicular to the length direction of the receiving cavity 3. The driving component 22 can be a valve motor, which can be a 24V low-voltage motor or a 12V low-voltage motor. The valve motor can be mounted through the side wall of the receiving cavity 3 and connected to the valve plate, driving the valve plate to rotate along the connection with the receiving cavity 3. The temperature sensor 5 can be set at the air inlet of the fuel cell engine or the gas outlet of the gas flow channel 4. The temperature sensor 5 senses the temperature of the air entering the fuel cell engine and transmits the sensed temperature data to the engine controller. The engine controller then transmits the sensed air temperature data to the engine controller. The temperature difference between the target intake air temperature and the target temperature is calculated to determine the required target cooling flow rate. This target cooling flow channel signal is then transmitted to the drive component 22 (valve motor). The valve motor controls the regulating component 21 (valve plate) to rotate and adjust to a specified position, ensuring the valve plate covers a specified area of ​​the receiving cavity 3. This allows the portion of the receiving cavity 3 through which the cooling medium can pass to reach a specified size, achieving a specified flow rate of the cooling medium in the cooling channel 1. This cools the high-temperature gas generated by the air compressor in the gas channel 4. After cooling the high-temperature gas to a specified temperature, it is delivered to the fuel cell engine through the gas channel 4, ensuring that the intake air temperature delivered to the fuel cell stack in the fuel cell engine reaches the specified temperature, thus improving the working efficiency of the fuel cell engine.This avoids the problems of excessive or insufficient heat dissipation performance in intercoolers, allowing them to adapt to different heat dissipation needs.

[0046] As can be seen from the above description of this disclosure, firstly, by setting an adjusting device 2 in the cooling channel 1, this application adjusts the flow rate of the cooling medium in the cooling channel 1, thereby enabling this disclosure to adapt to different cooling requirements and avoid the problems of excessive or insufficient heat dissipation performance.

[0047] Second: This application also wirelessly connects the temperature sensor 5 to the engine controller and drive unit 22, which enables intelligent control of the flow rate of the cooling medium in the cooling channel 1. At the same time, it ensures that the intake air temperature entering the fuel cell engine reaches the specified temperature, thereby increasing the service life of the fuel cell engine and improving the working efficiency of the fuel cell motor.
