Description

Technical Field

[0001] This utility model relates to the field of filters, and in particular to a water filter that can integrate deionization function. Background Technology

[0002] The cooling channels of a hydrogen fuel cell stack are narrow, requiring high cleanliness of the coolant. A water filter is needed to remove impurities larger than 300 μm to prevent blockage and ensure proper cooling. Hydrogen fuel cell systems also require high coolant conductivity, typically no greater than 5 μS / cm. Over time, various cations and anions will precipitate in the cooling system, necessitating a deionizer to absorb these ions and maintain appropriate conductivity. However, both the water filter and the deionizer are independent structures with limited functionality, making their integration into the overall system difficult and space-consuming. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a water filter that can integrate deionization function. It features an integrated design that simultaneously filters impurities and absorbs ions, has a simple layout, and occupies little space.

[0004] The present invention provides a water filter with integrated deionization function, comprising a water filter body and a deionizer body; the water filter body includes a housing and a filter screen disposed within the housing, the front end of the housing is a main water inlet pipe and the rear end is a main water outlet pipe; the two ends of the deionizer body are respectively connected to two points of the water filter body, and the connection points are all located behind the filter screen.

[0005] Preferably, the middle part of the shell is the filter cylinder section, and the cross-sectional dimensions of the main water inlet pipe section and the main water outlet pipe section are both smaller than the cross-sectional dimensions of the filter cylinder section.

[0006] Preferably, the filter screen is disposed inside the filter cylinder.

[0007] Preferably, the front end of the deionizer body is an inlet pipe section, and the rear end is an outlet pipe section. The inlet pipe section is sealed and connected to the filter cylinder section through a flange one, and the outlet pipe section is sealed and connected to the main water outlet section through a flange two.

[0008] Preferably, the filter screen is made of metal.

[0009] Preferably, the filter screen is welded or installed inside the housing by fasteners.

[0010] Compared with the prior art, this utility model has the following beneficial technical effects: This utility model integrates the water filter body and the deionizer body, simultaneously filtering impurities and absorbing ions. It features a simple layout, reduces pipe connections, has a compact structure, and occupies little overall space. After impurities are filtered out by the filter screen, water flows through branch one and branch two. Branch two directs the water to the deionizer body for deionization treatment.

[0014] like Figure 1 and Figure 2 As shown in the figure, the water filter with integrated deionization function proposed in this embodiment includes a water filter body and a deionizer body 3.

[0015] The water filter body includes a housing 1 and a filter screen 2 disposed within the housing 1. The housing 1 has a filter cylinder section in the middle, a main inlet pipe section 11 at the front end, and a main outlet pipe section 12 at the rear end. The filter screen 2 is specifically disposed inside the filter cylinder section, filtering impurities from the water entering the housing 1 through the main inlet pipe section 11. The cross-sectional dimensions of both the main inlet pipe section 11 and the main outlet pipe section 12 are smaller than the cross-sectional dimensions of the filter cylinder section, ensuring sufficient cross-sectional area and water flow rate for the filter cylinder section. The larger area of ​​the filter screen 2 results in better filtration.

[0016] The filter screen 2 is made of metal. The filter screen 2 is welded or installed inside the housing 1 by fasteners. Friction welding can be used for welding, and screws can be used for fastener installation.

[0017] like Figure 1 As shown, the deionizer body 3 is connected to the water filter body at both ends, and the connections are both located behind the filter screen 2. This means the water is first filtered to remove impurities before undergoing ion absorption. Specifically, the front end of the deionizer body 3 is the inlet pipe 31, and the rear end is the outlet pipe 32. The inlet pipe 31 is sealed to the filter cylinder via flange 311, and the outlet pipe 32 is sealed to the main outlet pipe 12 via flange 321. Both flanges are fastened to the water filter body, forming an integrated structure.

[0018] This embodiment integrates the water filter body and the deionizer body 3, simultaneously filtering impurities and absorbing ions. It features a simple layout, reduced piping connections, a compact structure, and a small overall footprint. Water enters through the main inlet pipe 11 of the housing 1, passes through the filter screen 2 to remove impurities, and then flows in two separate paths: branch path one and branch path two. In branch path one, water continues to flow through the filter cylinder to the main outlet pipe 12. In branch path two, water is diverted to the deionizer body 3 for deionization treatment, and then flows back to the main outlet pipe 12 where they converge and are discharged together.

[0019] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
