[0058] The following is a detailed description of some embodiments of the present invention through exemplary figures. In terms of adding reference numerals to the constituent elements of each figure, the same constituent elements are given the same reference numerals as much as possible even if they are shown in different figures. In addition, in describing the embodiments of the present invention, if it is judged that the specific description of the relevant known structure or function hinders the understanding of the embodiments of the present invention, its detailed description will be omitted.

[0059] In this specification, the front-back, left-right, and up-down directions are referred to for the convenience of explanation and may be directions orthogonal to each other. However, such directions are relatively determined with respect to the arrangement direction of the objects, and the up-down direction does not necessarily refer to the vertical direction.

[0060] In one or more embodiments, a heat exchanger assembly for a ship hull that can improve cooling efficiency and ensure robustness can be provided.

[0061] The heat exchanger assembly for a ship hull according to an embodiment of the present invention may be a heat exchanger assembly for a ship hull for cooling a fuel cell installed in a ship.

[0062] The basic principle of a fuel cell is described in detail below. A fuel cell stack may include a plurality of cells. A cell may include a membrane-electrode assembly (Membrane Electrode Ass embly) (not shown) with an electrolyte membrane through which hydrogen ions move as the center, catalyst electrode layers for electrochemical reactions being attached to both sides of the membrane, a gas diffusion layer (Gas Diffusion Layer) (not shown) that serves to evenly distribute the reaction gas and transfer the generated electrical energy, and a separation plate (bipolar plate) (not shown) that moves the reaction gas and cooling water.

[0063] More specifically, in the stack, hydrogen as fuel and oxygen as oxidant are respectively supplied to the anode and cathode of the membrane-electrode assembly through flow channels of the separation plate. Here, hydrogen may be supplied to the anode and air may be supplied to the cathode.

[0064] The hydrogen supplied to the anode is decomposed into protons and electrons by catalysts of electrode layers arranged on both sides of the electrolyte membrane, wherein only the protons selectively pass through the electrolyte membrane as a cation exchange membrane and are transferred to the cathode, while the electrons can be transferred to the cathode through the gas diffusion layer and the separator as a conductor.

[0065] In the cathode, the hydrogen ions supplied through the electrolyte membrane and the electrons transferred through the separator can meet the oxygen in the air supplied to the cathode through the air supply device to trigger a reaction that produces water. Due to the movement of the hydrogen ions at this time, electrons flow through the external wire, and current can be generated by this flow of electrons.

[0066] As an example, the hull heat exchanger assembly may be an assembly of a heat exchanger for cooling an electrical device of a fuel cell and a heat exchanger for cooling a stack of fuel cells. Figure 1 2 is a diagram showing a heat exchanger assembly for a ship hull according to an embodiment of the present invention. Figure 2 yes Figure 1 Exploded three-dimensional diagram. Figure 3 From the other direction Figure 2 . Figure 4 1 is a diagram showing a main body of a heat exchanger assembly for a ship hull according to an embodiment of the present invention.

[0067] A heat exchanger assembly for a hull according to an embodiment of the utility model may include a first heat exchange part 100, a second heat exchange part 200 and a body part 300. The first heat exchange part 100 may be configured to cool a fuel cell electrical device in the ship. The second heat exchange part 200 may be configured to cool a fuel cell stack in the ship.

The second heat exchange part 200 may include a 2-1 pipe 201, a 2-2 pipe 202, a 2-3 pipe 203, and a 2-4 pipe 204. Two of the pipes may be pipes for fluid inflow, and the remaining two are pipes for fluid discharge.

[0069] The body part 300 may connect the first heat exchange part 100 and the second heat exchange part 200 to each other. The body part 300 may include a first opening 301 ( Figure 3 ) and the second opening 302 ( Figure 2 ). The direction of the main body 300 toward the first heat exchange part 100 is defined as the first direction D1. The first opening 301 opens in the first direction D1, and the first heat exchange part 100 can be arranged inside. The second opening 302 opens in the second direction D2 which is the opposite direction of the first direction D1, and the second heat exchange part 200 can be arranged inside.

[0070] As an example, the first heat exchange part 100 and the second heat exchange part 200 may be fixed by accommodating the body part 300 connecting the first heat exchange part 100 and the second heat exchange part 200, thereby improving the robustness of the heat exchanger assembly.

[0071] The body portion 300 may include a first heat dissipation component 310 , a second heat dissipation component 320 and a body component 330 . The first heat dissipation component 310 may include a first opening 301 . The second heat dissipation component 320 is disposed on the second direction D2 side of the first heat dissipation component 310 and may include a second opening 302 .

[0072] The body part 330 is disposed between the first heat dissipation part 310 and the second heat dissipation part 320, and can connect the first heat dissipation part 310 and the second heat dissipation part 320. As an example, the lengths of the first heat dissipation part 310, the second heat dissipation part 320 and the body part 330 in the vertical direction can correspond to each other. As an example, the area where the first heat dissipation part 310 and the body part 330 contact and the area where the second heat dissipation part 320 and the body part 330 contact can be laser welded.

[0073] The length of the first heat radiation part 310 in the first direction D1 may be different from the length of the second heat radiation part 320 in the first direction D1. This means that the length of the first heat exchange part 100 in the first direction D1 may be different from the length of the second heat exchange part 200 in the first direction D1.

[0074] The first heat exchange part 100 may include a plurality of first plate-like components 110 stacked along the first direction D1. For reference, the figure shows that the first plate-like component 110 is one component, but it should be understood that this is only an example, which is for the convenience of illustration. The second heat exchange part 200 may include a plurality of second plate-like components 210 stacked along the second direction D2. The plurality of first plate-like components 110 are arranged in the first opening 301, and the plurality of second plate-like components 210 may be arranged in the second opening 302.

[0075] The number of the first plate-shaped parts 110 and the number of the second plate-shaped parts 210 may be different. The length of the first heat dissipation part 310 along the first direction D1 may correspond to the length of the stacked plurality of first plate-shaped parts 110 along the first direction D1. The length of the second heat dissipation part 320 along the second direction D2 may correspond to the length of the stacked plurality of second plate-shaped parts 210 along the second direction D2.

[0076] The body part 300 not only ensures the firmness between the first heat exchange part 100 and the second heat exchange part 200, but also plays a role in assisting the cooling of the first heat exchange part 100 and the second heat exchange part 200. The structure of the body part 300 for assisting the cooling of the first heat exchange part 100 and the second heat exchange part 200 is described in detail below.

[0077] The first heat dissipation component 310 may include a first heat dissipation component body 311 and a first heat dissipation fin portion 312. The first heat dissipation component body 311 may be a portion defining the first opening 301. The first heat dissipation fin portion 312 may protrude in the second direction D2 from a surface on the second direction D2 side of the first heat dissipation component body 311. The first heat dissipation fin portion 312 may be a structure for increasing a surface area in order to effectively dissipate heat dissipated from the first heat exchange portion 100 through the first heat dissipation component body 311.

[0078] The second heat dissipation component 320 may include a second heat dissipation component body 321 and a second heat dissipation fin portion 322. The second heat dissipation component body 321 may be a portion defining the second opening 302. The second heat dissipation fin portion 322 may protrude from a surface of the second heat dissipation component body 321 on the first direction D1 side thereof in the first direction D1. The second heat dissipation fin portion 322 may be a structure for increasing a surface area in order to effectively dissipate heat dissipated from the second heat exchange portion 200 through the second heat dissipation component body 321.

[0079] The first heat sink portion 312 may be formed in plurality and arranged in the up-down direction, and the second heat sink portion 322 may be formed in plurality and arranged in the up-down direction.

[0080] The body part 300 has an inner hole 331 extending along the first direction D1, and the first heat sink part 312 and the second heat sink part 322 can be arranged in the inner hole 331. In addition, the body part 330 may include an inflow channel 332 and an exhaust channel 333. The inflow channel 332 may be configured to communicate with the inner hole 331 and flow in an external cooling fluid. The exhaust channel 333 may be configured to communicate with the inner hole 331 and exhaust an external cooling fluid. The cooling fluid flowing into the inner hole 331 may be a structure for cooling the first heat dissipation part 310 and the second heat dissipation part 320.

[0081] As an example, the cooling of the first heat exchange part 100 and the second heat exchange part 200 is assisted by the action of the body part 300, so that the firmness of the first heat exchange part 100 and the second heat exchange part 200 can be maintained and the cooling efficiency of the heat exchanger assembly can be improved.

[0082] As an example, the heat exchanger assembly includes a member for connecting the heat exchanger for the electric device and the heat exchanger for the stack to each other, thereby ensuring the robustness of the heat exchanger assembly.

[0083] In addition, as an example, since the component that connects the heat exchanger for electric equipment and the heat exchanger for stack to each other plays a role of assisting the cooling of the heat exchanger, the cooling efficiency can be improved.
