Furthermore, conflicting piping routes, low space utilization, and a lack of rational planning in the layout of core components within the equipment lead to insufficient ease of maintenance. In addition, existing designs often result in cabinet doors obstructing maintenance access during maintenance, severely impacting the accessibility and safety of maintenance operations, and potentially delaying processing time, especially in emergency maintenance scenarios. Utility Model Content

[0003] The purpose of this utility model is to solve the problems of existing power distribution systems with external padlocks lacking mandatory operation procedures, posing a risk of omission, and failing to meet the application requirements of high safety levels; or the method of adding fixed locks to the outside of equipment doors to restrict handle operation, which is difficult to control due to manual operation of the switch, and the fixed locks added to the outside of the door can easily injure hands; in addition, the fixed locks on the door occupy door space, thereby squeezing the installation space of electrical displays; and some locking devices are only applicable to rotary switches of specific models or sizes, with poor versatility. The present invention provides a cooling capacity distribution unit.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a cold energy distribution unit, characterized in that it includes a cabinet, a plurality of cabinet doors disposed on the cabinet, and a pipeline assembly disposed in the cabinet; the pipeline assembly includes a primary pipeline assembly, a secondary pipeline assembly, and a heat exchange component connected to the primary and secondary pipelines; a liquid storage component is also disposed in the cabinet, the liquid storage component is connected to the pipeline assembly through a liquid replenishment pipeline, and a pressure regulating component is also disposed on the pipeline assembly. By utilizing primary and secondary piping assemblies and heat exchange components, a compact piping layout can be achieved while effectively ensuring heat exchange performance. A 4.5-inch primary side and a 4-inch secondary side are completed within a limited space, effectively improving the rationality of the internal component layout and reducing the space required by the cabinet. Furthermore, by incorporating multiple cabinet doors, the average door width is reduced, preventing doors from obstructing maintenance access and hindering personnel movement. This improves accessibility and safety during maintenance and allows operators to perform maintenance from the front of the cabinet, significantly enhancing convenience. Additionally, the use of a liquid replenishment component allows for effective replenishment of the secondary piping assembly, ensuring heat exchange performance, while the use of a pressure regulating component effectively counteracts pressure fluctuations within the piping assembly, ensuring pressure balance.

[0005] Furthermore, the heat exchange component is a plate heat exchanger, and a low-voltage electrical control box is installed on the cabinet door, while a high-voltage electrical control box is installed inside the cabinet. Utilizing a plate heat exchanger effectively ensures the heat exchange effect between the primary and secondary piping components. Additionally, a water quality detection component is installed on the plate heat exchanger to effectively monitor the water quality within it. By placing the low-voltage electrical control box on the cabinet door, the door can be rotated open for operation and maintenance of the low-voltage control box.

In other embodiments provided by this utility model, the filter can be a Y-type filter, etc. By using the control valve, the opening or closing of the pipe on the barrel filter side can be effectively controlled, so that the cooled water after heat exchange in the plate heat exchanger flows into the secondary side outlet pipe and into the barrel filter for filtration, or flows directly out from the secondary side outlet pipe, thereby further improving the rationality of the pipe layout in the cabinet and improving the convenience of filter maintenance. In addition, a flow meter is also provided on the secondary side outlet pipe, so as to effectively monitor the liquid flow rate in the secondary side outlet pipe and ensure the stability of the liquid flow rate.

[0011] Furthermore, the liquid storage component is a liquid storage tank, and the liquid replenishment pipeline includes an internal liquid replenishment pipeline connected to the circulation pump and an external liquid replenishment pipeline connected to the liquid storage tank for filling.
