[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides an implementation scheme: Currently, box-type evaporators are usually placed directly in a water tank to cool the water inside. This results in the water, which is used as the working fluid, being in direct contact with the coils and fins of the evaporator. However, after prolonged use, the water quality deteriorates, carrying some dust and heavy metal ions, causing corrosion and contamination of the evaporator's coils and fins, affecting heat dissipation efficiency, and making cleaning inconvenient.

[0020] To address the aforementioned issues, this application discloses an evaporator water tank purification structure 5, comprising a main container, a main body 1, which is a rectangular hollow shell used to hold water to be cooled. Several heat exchange coils 2, which are core heat exchange components, are installed inside the main body 1. The heat exchange coils 2 are made of copper or corrosion-resistant alloy. Inlet pipes 3 and outlet pipes 4 are respectively installed at both ends of the heat exchange coils 2 for introducing refrigerant and discharging refrigerant after heat exchange. A core purification structure 5 is provided on the side of the main body 1 to prevent contamination of the heat exchange coils 2.

[0021] According to the instruction manual Figure 1-3 As can be seen, the aforementioned water purification structure 5 includes an inlet pipe 51 for introducing external water, which is connected to the main tank 1. A circulation pump 53 is installed between the inlet pipe 51 and the main tank 1 to provide power for the circulation of water in the purification circuit. A purified water tank is connected to one side of the inlet pipe 51. The purified water tank serves as the core container for purification treatment. A buffer tank 55 is provided on one side of the purified water tank. Water from the outside first enters the buffer tank 55 to stabilize the water flow. Several clean water tanks 54 are arranged in a linear array on one side of the buffer tank 55. The buffer tank 55 is connected to a clean water tank 54 through several water inlets on one side. Each clean water tank 54 is filled with a core purification element, a water purification cylinder 56. The water purification cylinder 56 is preferably an ultrafiltration membrane cylinder, such as a UF membrane. The top of the clean water tank 54 is threaded with a sealing seat 57 for easy replacement and maintenance. A discharge pipe 584 is provided on the sealing seat 57 and extends into the inner cavity of the water purification cylinder 56. The end of the discharge pipe 584 is connected to the water outlet pipe 52. The water outlet pipe 52 is connected to the main tank 1 to transport the purified water back to the main tank 1.

[0022] Workflow: Water from the main tank 1 and supplemental water enter the system through the inlet pipe 51. The water then flows into the buffer tank 55 of the purified water tank to stabilize the flow rate. The stabilized water flow is then evenly distributed to each purified water tank 54 through the inlet. In each purified water tank 54, driven by the pressure provided by the circulation pump 53, the water permeates from the outside of the purified water cylinder 56 (i.e., the ultrafiltration membrane cylinder) inwards. Water molecules and smaller ions and dissolved substances can pass through the ultrafiltration membrane into the inner cavity of the purified water cylinder 56, while suspended particles, colloids, bacteria, and other pollutants in the water are trapped outside the membrane. The purified water is collected... The clean water flows out through the discharge pipe 584 on the sealing seat 57 from the inner cavity of the water purification cylinder 56. All the clean water from the discharge pipe 584 is collected in the water outlet pipe 52 and finally transported back to the main housing 1. This process is continuously cyclical. The water in the main housing 1 is continuously drawn out, purified and then returned, so that the water in contact with the heat exchange coil 2 is always clean water that has undergone ultrafiltration treatment. This effectively avoids the deposition of scale and dirt on the surface of the heat exchange coil 2 and fins and the corrosion of metal by heavy metal ions, significantly improves the heat exchange efficiency and extends the service life of the evaporator. The water purification cylinder 56 can be replaced in time.

[0023] As a preferred option, the water purification cylinder 56 is a cylindrical membrane cylinder, and a ring-shaped guide seat is provided on the water purification tank 54. The guide seat is inserted into the bottom end of the water purification cylinder 56. The function of the guide seat is to ensure that the water purification cylinder 56 is accurately positioned in the water purification tank 54, prevent installation deviation, ensure that the water flow is evenly distributed through the surface of the ultrafiltration membrane, and avoid local blockage or poor sealing.

[0024] As a preferred option, a pair of control valves 59 are provided on the inlet pipe 51 and the outlet pipe 52. The function of these control valves 59 is to facilitate the separate control of the inlet water circuit and the purified water circuit, to isolate the corresponding pipes when maintenance is required, or to adjust the flow rate during system debugging.

[0025] As a preferred option, the bottom of the sealing seat 57 is provided with a ring-shaped pressure sleeve, which is pressed against the top of the water purification cylinder 56. The pressure sleeve, the water purification cylinder 56, and the sealing seat 57 are mutually sealed. The function of the pressure sleeve is to press down on the top of the water purification cylinder 56 when the sealing seat 57 is tightened, and at the same time form a reliable annular sealing surface between the top of the water purification cylinder 56, the inner edge of the pressure sleeve, and the bottom of the sealing seat 57, effectively preventing unfiltered water from leaking from the gap between the top of the water purification cylinder 56 and the sealing seat 57, and ensuring that only water filtered by the ultrafiltration membrane can enter the discharge pipe 584.

[0026] As a preferred option, a pre-filter 6 is further provided between the water purification tank and the inlet pipe 51. The function of the pre-filter 6 is to pre-intercept large particles of impurities, silt, rust, etc. in the water, preventing these impurities from entering the water purification tank 54 and clogging the ultrafiltration membrane pores or scratching the membrane surface, effectively protecting the expensive ultrafiltration membrane cartridge and extending its service life.

[0027] As a preferred option, the end of the discharge pipe 584 is provided with a connector that communicates with the water outlet pipe 52. The function of this connector is to provide a reliable and easy-to-disassemble connection. The specific form of the connector can be a flange or a plug, to ensure that the connection between the discharge pipe 584 and the water outlet pipe 52 is tight and leak-free, and at the same time, it is convenient to disconnect the connection during maintenance.

[0028] In summary, the evaporator water tank purification structure 5, by setting up an independent purification water circulation loop based on an independent purification water tank, has a simple and highly modular structure with a small footprint. It uses an ultrafiltration membrane cartridge to continuously filter and purify the working fluid water in the tank, completely isolating the pollution source from direct contact with the heat exchange surface of the evaporator. When the purification water cartridge 56 needs to be replaced, simply unscrew the sealing seat 57 to remove the old cartridge and install the new cartridge. Maintenance is simple, solving the pain points of traditional evaporators caused by water quality deterioration, such as reduced efficiency, corrosion, and difficulty in cleaning.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
