Description

Technical Field

[0001] This invention relates to humidifiers, and more specifically, to humidifiers applicable to fuel cell systems. Background Technology

[0002] Humidifiers used in fuel cell systems are devices for appropriately regulating the humidity of the air supplied to the fuel cell, and are necessary for optimizing the performance and lifespan of the fuel cell. The aforementioned humidifiers typically operate by using exhaust water discharged from the fuel cell stack to regulate the humidity of the air supplied to the fuel cell.

[0003] On the other hand, when water accumulates on the floor inside the humidifier, a large amount of air may suddenly flow into the humidifier depending on the output required by the fuel cell system. At this time, according to existing technology, the water accumulated on the humidifier floor may disperse and come into contact with the humidification membrane due to the airflow, which can accelerate the chemical degradation of the humidification membrane. In particular, according to existing technology, in certain areas of the humidification membrane inside the humidifier, proper sweeping by fluids such as air is not possible, leading to frequent humidification membrane degradation. Summary of the Invention

[0004] Therefore, the object of the present invention is to improve the structure of the humidifier so as to minimize the deterioration of the humidifying membrane inside the humidifier.

[0006] The humidifier may also include a fixing part that is housed inside the intermediate housing component, and at least one side of the core is fixed to the fixing part. A portion of the core protrudes from the fixing part to both sides of a second direction (D2) that intersects the first direction (D1).

A stepped area formed by the connection of portions of different thicknesses is formed in the first window region or the second window region.

[0008] The aforementioned window area can be formed such that the thickness of the portion located on the outer side in the second direction (D2) with the aforementioned step interval as the boundary is thinner than the thickness of the portion located on the inner side in the second direction (D2) with the aforementioned step interval as the boundary.

[0009] The humidifier may also include a fixing part housed inside the intermediate housing component, and at least one side of the core is fixed to the fixing part. A portion of the core protrudes from the fixing part to both sides of a second direction (D2) intersecting the first direction (D1). A bypass space is formed between the fixing part and the inner side of the intermediate housing component, communicating i) a space for accommodating the portion of the core protruding from the fixing part to the side of the second direction (D2) and ii) a space for accommodating the portion of the core protruding from the fixing part to the other side of the second direction (D2).

[0010] The first hole and the second hole can be formed on a side of the intermediate housing component on a third direction (D3) that intersects the first direction (D1) and the second direction (D2). The bypass space is configured such that the core is located in the middle on the third direction (D3) and is opposite to the first hole.

[0012] The humidifier may also include a fixing part housed inside the intermediate housing component, and at least one side of the core component is fixed to the fixing part. A portion of the core component protrudes from the fixing part to both sides of a second direction (D2) intersecting the first direction (D1). The first hole and the second hole are respectively formed on one side of the intermediate housing component in the direction intersecting the second direction (D2). At least a portion of the plurality of core components has a window region with a through hole. The window region may include: a first window region disposed on one side of the core component in the second direction (D2) toward the direction of the first hole, and having one or more first through holes; and a second window region disposed on one side of the core component in the second direction (D2) toward the direction of the second hole, and having one or more second through holes, wherein i) the first window region is disposed at a position spaced apart from the first hole toward the outside of the second direction (D2), or ii) the second window region is disposed at a position spaced apart from the second hole toward the outside of the second direction (D2).

[0013] The first hole can be formed on one side of the intermediate housing component in a third direction (D3) that intersects the first direction (D1) and the second direction (D2), and the second hole can be formed on the other side of the intermediate housing component opposite to the side of the third direction (D3).

[0014] The first hole can be formed on a side of the intermediate housing component in a third direction (D3) that intersects the first direction (D1) and the second direction (D2), and the second hole can be formed on a side of the intermediate housing component in the first direction (D1).

[0015] The humidifier may also include a fixing part housed inside the intermediate housing component, and at least one side of the core is fixed to the fixing part. A portion of the core protrudes from the fixing part to both sides of a second direction (D2) intersecting the first direction (D1). At least a portion of the plurality of core components has a window area with a through hole formed therein. The window area is formed on one side of the plurality of core components in the first direction (D1). An exhaust hole is formed on one side of the plurality of core components in the direction intersecting the first direction (D1).

[0016] The aforementioned discharge hole is formed on one side of a third direction (D3) that intersects the first direction (D1) and the second direction (D2) of the aforementioned plurality of core components.

[0017] The aforementioned window area may include: a first window area, which is disposed on one side of the second direction (D2) of the aforementioned core component and has one or more first through holes; and a second window area, which is disposed on the other side of the second direction (D2) of the aforementioned core component and has one or more second through holes. The aforementioned discharge hole may include: a first discharge hole, which is formed to overlap with the aforementioned first window area in the second direction (D2); and a second discharge hole, which is formed to overlap with the aforementioned second window area in the second direction (D2).

[0018] The aforementioned discharge hole can be formed as the outer end of the two ends in the second direction (D2) that are relatively closer to the aforementioned window area.

[0019] The humidifier may also include a pipe section connected to a side of the intermediate housing component on a third direction (D3) intersecting the first direction (D1) and the second direction (D2). At least a portion of the plurality of core components has a window region with a through hole. The window region may include: a first window region disposed on one side of the core component in the second direction (D2) and having one or more first through holes; and a second window region disposed on the other side of the core component in the second direction (D2) and having one or more second through holes. The portion of the pipe section connected to the intermediate housing component is configured to be spaced apart from the first window region and the second window region in the second direction (D2).

[0020] The portion of the pipe section that connects to the intermediate housing component can be located between the first window area and the second window area in the second direction (D2).

[0029] The humidifier based on the present invention will now be described with reference to the accompanying drawings.

[0031] The humidifier based on the present invention can be applied to a fuel cell system. More specifically, the humidifier based on the present invention can be a device that maximizes the driving efficiency of a fuel cell by humidifying the air required to drive the fuel cell.

[0032] Reference Figures 1 to 3 The humidifier 10 based on the present invention can include: an intermediate housing component 100 having a first hole (H1) formed on one side and a second hole (H2) formed on the other side, and having a space formed inside; and a core 200 including a plurality of core components 210 housed inside the intermediate housing component 100. More specifically, the core components 210 can be configured to be spaced apart from each other in a first direction (D1). In addition, the humidifier 10 based on the present invention can include a humidifying film component 300 housed inside each core component 210. As an example, the accompanying drawings show a state in which three core components 210 are arranged along the first direction (D1) within the intermediate housing component 100.

[0033] On the other hand, the first orifice (H1) provides a flow path for fluid (e.g., a water-containing fluid discharged from the fuel cell) to flow into the humidifier 10, and the second orifice (H2) provides a flow path for discharging fluid from the interior of the humidifier 10 to the exterior. In this case, according to the present invention, means for generally reducing the flow rate of the fluid flowing in through the first orifice (H1) can be applied.

[0034] More specifically, according to the present invention, such as Figure 2 As shown, the two ends of the plurality of core components 210 in the first direction (D1) can be located within the width of the first direction (D1) of the first hole (H1) of the intermediate housing component 100. Figure 2 Reference numeral A in the accompanying drawings. That is, as shown in the drawings, when the core 200 is composed of three core components 210, the two ends of the three core components 210 in the first direction (D1) can be located within the width of the first hole (H1) in the first direction (D1). In this case, fluid flowing into the interior of the intermediate housing component 100 through the first hole (H1) can flow into the interior space of the intermediate housing component 100 through i) the space between the intermediate housing component 100 and the outermost core component 210, and ii) the space between two adjacent core components 210, thus increasing the cross-sectional area of ​​the fluid flow area in the inlet region of the humidifier. Furthermore, according to the present invention, during the flow of fluid into the humidifier, all of the multiple core components 210 disposed in the core 200 can come into contact with the fluid. The two factors mentioned above are factors that reduce the flow rate of the fluid supplied to the humidifier. Therefore, according to the present invention, when fluid is supplied to the humidifier, the water accumulated in the intermediate housing component 100 is reduced in the degree of scattering due to the flow rate of the fluid flowing in through the first hole (H1), which results in minimizing direct contact between the scattered water and the humidification membrane component 300.

[0035] On the other hand, such as Figure 1 and Figure 4 As shown, the humidifier 10 based on the present invention may further include a fixing portion 400, which is housed inside the intermediate housing member 100, and at least one side of the core portion 200 is fixed to the fixing portion 400. More specifically, at least one side of the core portion 200 can be fixed to the fixing portion 400. In this case, according to the present invention, a portion of the core portion 200 can protrude from the fixing portion 400 to both sides of a second direction (D2) intersecting the first direction (D1). As an example, the first direction (D1) and the second direction (D2) can each be horizontal, and the first direction (D1) and the second direction (D2) can be perpendicular to each other.

[0036] On the other hand, such as Figure 1 As shown, according to the present invention, the core portion 200 may have an asymmetrical shape centered on the fixing portion 400. More specifically, the length of the core portion 200 protruding from the fixing portion 400 in the second direction (D2), i.e., the first length, and the length protruding to the other side, i.e., the second length, may be different from each other.

[0037] On the other hand, according to an example of the present invention, the first hole (H1) and the second hole (H2) can be formed on a side of the intermediate housing member along a third direction (D3) that intersects the first direction (D1) and the second direction (D2). As an example, the third direction (D3) can be a vertical direction, and the first hole (H1) and the second hole (H2) can be formed on the upper surface of the intermediate housing member 100, respectively.

[0038] Additionally, refer to Figure 1 and Figure 3 At least a portion of the multiple core components 210 can form window regions 220, which have through holes 227. Fluid within the intermediate housing component 100 can flow into the core component 210 through the window regions 220, thereby humidifying the air in the humidification membrane component 300 through water vapor exchange between the fluid and the air to be flowed into the fuel cell. As an example, the accompanying drawings show three rows of through holes 227 arranged on each side of the intermediate housing component 100 in a second direction (D2) within the window regions 220.

[0039] On the other hand, the window region 220 may include: a first window region 222, which is disposed on one side of the core member 210 in the second direction (D2) and forms one or more first through holes 227; and a second window region 224, which is disposed on the other side of the core member 210 in the second direction (D2) and forms one or more second through holes 227. As shown in the figures, the first window region 222 may be configured to be adjacent to the first hole (H1), and the second window region 224 may be configured to be adjacent to the second hole (H2).

[0040] Then as Figure 1 and Figure 3 As shown, a stepped section 226, formed by the connection of portions of different thicknesses, can be formed in the first window region 222 or the second window region 224. The stepped section 226 can extend in a direction parallel to the third direction (D3). This can be understood as the window region on one side of the stepped section 226 in the second direction (D2) having the stepped section 226 as its boundary having a thickness different from the window region on the other side of the stepped section 226 in the second direction (D2). More specifically, the window region 220 can be formed such that the portion on the outer side of the stepped section 226 in the second direction (D2) has a thinner thickness than the portion on the inner side of the stepped section 226 in the second direction (D2).

[0041] According to the prior art, in the window region, the portion relatively located on the outer side is a so-called dead zone, which is a region where it is relatively difficult to supply fluid for rinsing away such water from the humidifying membrane component when water accumulated inside the intermediate housing component splashes and adheres to it. At this time, as described above, when the thickness of the portion of the window region 220 located on the outer side in the second direction (D2) with the step interval 226 as the boundary is relatively thin, the fluid can flow more smoothly into the interior of the intermediate housing component 100 through the through holes 227 in the portion of the window region 220 located on the outer side in the second direction (D2), and therefore can more smoothly rinse away water from the humidifying membrane component. As an example in the accompanying drawings, the thickness of the portion formed by the outermost through hole in the second direction (D2) of the three rows of through holes 227 arranged along the second direction (D2) formed in the first window region 222 and the second window region 224 is shown to be relatively thin with the step interval 226 as the boundary.

[0042] On the other hand, according to the present invention, the length by which the core 200 protrudes from the fixing portion 400 into the first hole (H1) in the second direction (D2), i.e., the first length, can be shorter than the length by which the core 200 protrudes from the fixing portion 400 into the second hole (H2) in the second direction (D2), i.e., the second length. This is to ensure that the fluid flowing into the intermediate housing component 100 through the first hole (H1) can flow uniformly into the through hole 227 formed in the first window region 222. In particular, according to the present invention, since the fluid flowing in through the first hole (H1) can also be smoothly supplied to the through hole 227 located outside the first window region 222 in the second direction (D2), the aforementioned dead zone region no longer exists according to the present invention.

[0043] Referring again to the accompanying drawings, the humidifier 10 based on the present invention may also include a structure for enabling fluid, including water, supplied to the intermediate housing component 100 through the first hole (H1) to move to a region adjacent to the second hole (H2) without passing through the core 200.

[0044] To be more detailed, such as Figure 1 and Figure 4 As shown, a bypass space (BP) can be formed between the fixing part 400 and the inner side of the intermediate housing component, which connects i) a space that accommodates a portion of the core 200 protruding from the fixing part 400 to the second direction (D2) and ii) a space that accommodates a portion of the core 200 protruding from the fixing part 400 to the other side of the second direction (D2).

[0045] More preferably, when the first hole (H1) and the second hole (H2) are formed on a side of the intermediate housing member 100 along a third direction (D3) intersecting the first direction (D1) and the second direction (D2), as described above, the bypass space (BP) can be positioned such that the core 200 is positioned between the first hole (H1) and the second hole (H2) along the third direction (D3). The accompanying drawings show a configuration where the first hole (H1) and the second hole (H2) are formed on the upper surface of the intermediate housing member 100, while the bypass space (BP) is formed on the inner side of the lower region of the intermediate housing member 100. Alternatively, as an example, a portion of the bypass space (BP) can be defined by the inner side of the intermediate housing member along the first direction (D1).

[0046] On the other hand, as described above, when the first hole (H1) and the second hole (H2) are respectively formed on a side of the intermediate housing member 100 in a direction intersecting the second direction (D2) (e.g., a third direction), the first window region 222 can be provided at a position spaced apart from the outside of the first hole (H1) towards the second direction (D2), or the second window region 224 can be provided at a position spaced apart from the outside of the second hole (H2) towards the second direction (D2). More preferably, the second window region 224 can be provided at a position spaced apart from the outside of the second hole (H2) towards the second direction (D2). In a preferred example of the present invention, such as Figure 1 As shown, at least a portion of the first window region 222 overlaps with the first hole (H1) in the second direction (D2), while the entire portion of the second window region 224 is spaced apart from the second hole (H2) in the second direction (D2). This is to prevent effluent from flowing into the humidifying membrane component through the through hole 227 formed in the second window region 244.

[0047] On the other hand, as described above, the first hole (H1) and the second hole (H2) can be formed on one side of the intermediate housing member 100 in the third direction (D3). However, unlike the above, the first hole (H1) can be formed on one side of the intermediate housing member 100 in the third direction (D3), while the second hole (H2) can be formed on the opposite side of the intermediate housing member 100 in the third direction (D3). Alternatively, the first hole (H1) can be formed on one side of the intermediate housing member 100 in the third direction (D3), while the second hole (H2) can be formed on the side in the first direction (D1).

[0048] Referring again to the accompanying drawings, the window region 220 based on the present invention can be formed on the side of the core component 210 in the first direction (D1). At this time, a discharge hole 228 can be formed on the side of the core component 210 in the direction intersecting the first direction (D1). As an example, the discharge hole 228 can be formed on a side of the core component 210 in the third direction (D3). When the third direction (D3) is a vertical direction, the discharge hole 228 can be formed on the lower surface of the core component 210.

[0049] The drain hole 228 can be a structure for discharging water flowing into the core component 210 to the outside. More preferably, the drain hole 228 can be formed at a position opposite to the window region 220 in a third direction (D3). More preferably, the drain hole 228 can be formed at positions opposite to the first window region 222 and the second window region 224 in a third direction (D3), respectively. That is, the drain hole 228 can include: a first drain hole formed to overlap with the first window region 222 in a second direction (D2); and a second drain hole formed to overlap with the second window region 224 in a second direction (D2). When the drain hole 228 is set to overlap with the window region 220 in the second direction (D2) (i.e., opposite to each other in a third direction (D3)), it has the advantage that water flowing into the core component 210 through the window region 220 can be smoothly discharged to the outside through the drain hole 228 by gravity. As an example, considering that the phenomenon of water adhering to the humidifying membrane component being flushed by fluid is relatively unlikely to occur in the outer region of the second direction (D2) of the window region 220, the discharge hole 228 can be formed at the outer end of the two ends of the second direction (D2) of the window region 220.

[0050] On the other hand, refer to Figure 1 and Figure 6 The humidifier 10 based on the present invention may further include a pipe section 500 connected to a side of the intermediate housing component 100 on a third direction (D3) that intersects the first direction (D1) and the second direction (D2). The pipe section 500 may be a structure that forms a flow path for water intermittently discharged from the fuel cell stack within the fuel cell system to flow in. That is, according to the present invention, the water flowing into the humidifier 10 based on the present invention may consist of i) water discharged from the fuel cell stack and flowing in through the aforementioned first hole (H1), and ii) water flowing in through the pipe section 500.

[0051] At this point, according to the present invention, the portion of the pipe section 500 connected to the intermediate housing member 100 can be configured to be spaced apart from the first window region 222 and the second window region 224 in the second direction (D2). This is to prevent water flowing into the humidifier 10 through the pipe section 500 from directly flowing into the humidifying membrane member 300 through the first window region 222 or the second window region 224. More preferably, as Figure 1 and Figure 6 As shown, the portion of the pipe section 500 that connects to the intermediate housing component 100 can be located between the first window region 222 and the second window region 224 in the second direction (D2).
