[0037] The present disclosure relates to the field of power supply systems. More particularly, the present disclosure relates to a cooling system for a power supply unit (PSU) panel to enhance efficiency, reliability, and maintenance of the PSU panel.

[0038] Conventional cooling systems integrated within PSU panels often suffer from several significant drawbacks. These systems can lead to space congestion, as internal cooling components compete for limited space with critical electrical parts, complicating the design and assembly process. They are also prone to maintenance challenges, as internal water circulation systems are difficult to access for repairs, increasing downtime and operational costs. Moreover, the risk of water leakage within the panel poses serious safety hazards, including electrical short circuits and sparking. Additionally, internal systems may hinder effective heat dissipation, leading to reduced cooling efficiency and potentially impacting the overall performance and reliability of the PSU unit.

[0039] To address the aforementioned issues inherent in conventional internal cooling systems, the present disclosure introduces an external cooling system designed to optimize space utilization, enhance safety, and simplify maintenance. By relocating the cooling components, such as a manifold assembly, and a flow switch outside the PSU panel, the proposed cooling system helps inminimizing internal congestion and eliminating the risk of water leakage within the panel. This external arrangement not only facilitates easier access for maintenance and troubleshooting but also improves overall cooling efficiency by allowing for better heat dissipation. The result is a more reliable and efficient PSU panel with reduced operational costs and increased safety.

[0041] Referring to FIG. 2B, and according to an embodiment, the present disclosure relates to a cooling system (200) for the PSU panel (100). The cooling system (200) is positioned outside the PSU panel (100), thereby offering advantages in terms of space utilization, safety, maintenance, and overall efficiency. The cooling system (200) includes an inlet manifold (202) that is configured to receive water from an external water source which is to be circulated or distributed to components of the PSU panel (100). The cooling system (200) includes a distribution manifold (204) connected to the inlet manifold (202). The distribution manifold (204) is configured to distribute or circulate the water evenly to a plurality of cooling channels (206) and / or components within the PSU panel (100).

[0042] In an embodiment, the distribution manifold (204) can include the plurality of cooling channels (206) configured to direct the water to various components within the PSU panel (100). It ensures that each cooling channel receives a balanced flow of water. The cooling channels (206) can be placed within the PSU panel (100) to absorb heat from the electrical components.

[0043] Referring to Figures 3A & 3B, the cooling system (200) can include a flow switch (300) positioned between the inlet manifold (202) and the distribution manifold (204). The flow switch (300) can be configured to monitor flow rate of the circulating water. The flow switch (300) can ensure that the water flow can be within a desired range to maintain effective cooling.

[0044] In an embodiment, the flow switch (300) can include a Hex nipple (302), a rubber 0-ring (306) & (322), a float assembly (308), a housing bracket (310), one or more cheese head screws (312), one or more plain washers (314), a proximity switch (316), a locking bracket (318), a flow switch tube (320), a malecoupling (324), and a ball value (326). The Hex Nipple (302) is a sealing component used on a hex nipple (302) to prevent leaks. The rubber O-ring (306) ensures a tight seal around the proximity switch, protecting it from moisture and dust. The float assembly (308) is a mechanism that rises or falls with the fluid level, activating the proximity switch (316) based on flow conditions. Further, the housing bracket (310) enclosure that houses the internal components, providing protection and stability. The housing bracket (310) can be manufactured of Molded Non-metallic Plastic. The cheese head screws (312) can be screws with a cylindrical head, used to secure various components together, often allowing for easy installation and removal. The plain washers (314) can be flat washers used to distribute the load of the screw, preventing damage to the housing bracket (310) and providing a better seal. The proximity switch (316) can detect the position of the float assembly (308) and sends signals based on the flow conditions.

[0045] The locking bracket (318) can secure the components in place, preventing movement or disassembly during operation. The flow switch tube (320) can be tubes through which fluid flows, connecting to the float assembly (308) and facilitating flow detection.

[0046] The Rubber O-Ring (306) can be a durable sealing component that provides resistance to wear and various chemicals, used in various joints. The male coupling (324) can be a connector that can allow attachment to other components in the system, typically facilitating flow into or out of the assembly. The ball valve (326) can control and monitor the flow of fluid in the system.

[0047] To assembly the flow switch, the proximity switch (316) is fixed within the housing bracket (310) moulded which is a non-metallic plastic moulded housing bracket, ensuring robust protection. A rubber "0” ring is then securely placed on the hex nipple (302) and male coupling (324) to provide a reliable seal.In an embodiment, the hex nipple (302) and the male coupling (324) can be made of non-metallic plastic material. Following this, the male coupling (324) and the hex nipple (302) are attached to the ball valve (326), establishing a secure connection. Next, the flow switch tube (320) made of polycarbonate is inserted into a slot of the male coupling, followed by the float assembly, which is prepped by affixing a stainless steel sensor cap to a top of a float made of brass with a brass screw and attaching a float disc to a bottom of the float. An additional non-metallic plastic "0” ring nipple is then fitted onto the flow switch tube (320) to ensure further integrity. The housing bracket (310) is positioned onto the slot of the male coupling (324) and the "0” ring type nipple, completing the internal structure. Finally, the assembled flow switch tube (320) is inserted into the locking bracket (318), and the housing bracket (310) is secured using a brass screw and a washer for added stability. To complete the assembly, an "LPM" mark is applied to the flow switch, signifying its operational parameters. This systematic assembly process results in a durable and efficient flow switch ready for installation and use.

[0048] In an implementation, in case the flow rate deviates from preset values, the flow switch (300) can send signals to a central control unit or alarm system to alert for adjustments or maintenance. During power supply on condition, to regulate min. required flow (5 to (100) Liters Per Minute (LPM) and beyond), the float assembly (308) lifts upper side of the flow switch (300) and proximity sensor pass on the signal as per the distance travel by the float assembly (308). During Panel running condition, when the flow is not in a proper requirement and float assembly (308) is not lifted upper side then proximity sensor not send the signal and trip the panel to avoid accident and safety purpose. A user can throttle flow with help of the ball valve (326).

[0049] As can be appreciated, the proposed design of the flow switch (300) represents a significant advancement in both functionality and efficiency. By integrating lightweight non-metallic plastic components, it ensures safe operation in higher voltage systems while simplifying installation. The use of plastic molded parts not only reduces manufacturing lead times but also contributes to cost savings — offering a price point that is 40% lower than traditional flow switches.

[0050] In an embodiment, the cooling system (200) can include an outlet manifold 208 connected to the plurality of cooling channels (206). Water flows through the cooling channels (206) inside the PSU panel (100), absorbing heat from the components. The outlet manifold 208 can be configured to transfer the heated water to the external water source which can be recirculated or processed further.

[0051] As can be appreciated, the proposed external cooling system (200) designed to optimize space utilization, enhance safety, and simplify maintenance. By relocating the cooling components, such as a manifold assembly, and the flow switch (300) outside the PSU panel (100), the proposed cooling system (200) helps in minimizing internal congestion and eliminating the risk of water leakage within the panel. This external arrangement not only facilitates easier access for maintenance and troubleshooting but also improves overall cooling efficiency by allowing for better heat dissipation. The result is a more reliable and efficient PSU Panel (100) with reduced operational costs and increased safety.

[0052] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention whencombined with information and knowledge available to the person having ordinary skill in the art.ADVANTAGES OF THE INVENTION
