Description

Technical Field

[0001] This utility model relates to the field of liquid replenishment device technology, and in particular to an automatic liquid replenishment device for an industrial and commercial energy storage thermal management system. Background Technology

[0002] In the industrial and commercial energy storage sector, with continuous technological advancements and increasing energy storage demands, the performance and reliability of energy storage systems have become a focal point of industry attention. As a crucial component of energy storage systems, the stable operation of the energy storage thermal management system directly impacts the efficiency and lifespan of the entire system. This is especially true in horizontal liquid-cooled temperature-controlled units, where components generate significant heat during operation, making effective heat dissipation and coolant circulation management paramount.

[0003] However, traditional industrial and commercial energy storage thermal management systems have several shortcomings in terms of liquid replenishment. Firstly, many temperature-controlled units lack liquid replenishment tanks, requiring specialized personnel and specialized negative / positive pressure pumps for each replenishment. This process is not only cumbersome but also time-consuming, increasing maintenance and time costs. Secondly, even when some temperature-controlled units have internal liquid replenishment tanks, inadequate design leads to increased overall unit dimensions, making them incompatible with current mainstream industrial and commercial energy storage unit sizes. This necessitates redesigning the cabinet dimensions in practical applications, increasing design complexity and manufacturing costs.

[0004] Furthermore, traditional temperature-controlled units also have limitations in their coolant replenishment methods. Some units simply add an expansion tank to reserve some coolant for system replenishment, but this method has limited capacity and cannot achieve automatic monitoring and control, leading to frequent problems of untimely or excessive coolant replenishment. This not only affects the stable operation of the energy storage system but may also damage components and shorten their service life. Utility Model Content

[0036] In an optional embodiment, a condenser 3 is installed on the side of the partition 11 near the mounting cavity.

[0037] It should be noted that condenser 3 further enhances heat dissipation, which helps extend the service life of components.

[0038] In an optional embodiment, the condenser 3 is mounted at an angle on the partition 11.

[0039] It should be noted that the tilted installation of the condenser 3 helps to increase the heat dissipation area and improve heat dissipation efficiency.

[0040] In an optional embodiment, the water replenishment assembly 4 includes a replenishment water tank 44 and a replenishment water pump 47 fixedly disposed in the mounting cavity. The replenishment water tank 44 is connected to a water inlet pipe 6 for adding water. The water inlet pipe 6 extends outside the outer casing 10. The replenishment water pump 47 draws out the liquid stored in the replenishment water tank 44 and sends it into the water cooling pipeline.

[0041] It should be noted that the water replenishment component 4 has an automatic liquid replenishment function, which solves the problems of cumbersome and long cycle of traditional liquid replenishment methods.

[0042] In an optional embodiment, the water replenishment assembly 4 includes a plate heat exchanger 48, which is fixedly installed on the inner wall of the outer casing 10 by a mounting bracket 13. One inlet of the plate heat exchanger 48 is connected to the replenishment water tank 44, and the plate heat exchanger 48 is connected to the water cooling pipeline.

[0043] It should be noted that the coolant temperature is adjusted by plate heat exchanger 48 to ensure that the components can operate stably under different ambient temperatures.

[0051] It should be noted that in cold weather, there is no need to dissipate heat from the components of the energy storage thermal management system. Instead, the components need to be heated to ensure stable operation. In this case, the liquid is heated by the PTC heater 49 to ensure that the components maintain a stable working environment.

[0052] The working principle of this utility model is as follows: The coolant tank 44 stores coolant and is filled with water through the water inlet pipe 6.

The plate heat exchanger 48 is fixed to the inner wall of the outer casing 10 via the mounting bracket 13 and is connected to the coolant tank 44 and the water-cooling pipeline for regulating the coolant temperature. The main water pump 41 and the expansion tank 42 are connected to the connecting water pipe 45 via the water circuit three-way valve 43. The connecting water pipe 45 is then connected to the drain pipe 5 and the coolant outlet pipe 46, realizing coolant circulation and pressure regulation. The PTC heater 49 heats the coolant in cold weather, ensuring that the components of the energy storage thermal management system operate in a stable working environment.
