Description

Be applied to energy storage thermal management system's liquid feeding frock

Technical Field

The utility model relates to an energy storage thermal management system, in particular to a liquid adding tool applied to the energy storage thermal management system.

Background

Expansion tanks are an important component in thermal management systems where the amount of expansion of the system water is accommodated while also providing a constant pressure and water make-up to the system. The expansion tank also serves to stabilize the pressure of the system and to expel air released by the water line during heating.

The expansion tank is needed to be located on the upper portion of the unit in order to achieve the effect of compensating cooling liquid for the cooling system, and when in actual use, the expansion tank is often needed to be charged with liquid, and the convenience of operation directly affects the quality of the unit. The liquid adding mode adopted at present is mostly to directly add liquid from the water adding port of the expansion tank, so that the height of the water adding port of the expansion tank from the ground is high, and the water adding space has high requirements. The existing scheme has the following defects:

1. personnel are required to watch in the whole process, and manpower is wasted. The on-site debugging personnel are short, and the expansion tank liquid feeding needs special arrangement personnel to observe the inside coolant liquid filling condition of expansion tank. When the expansion water tank reaches a certain liquid level, another person is arranged to close the water pump in time, so that the overflow of the cooling liquid is prevented.

2. The time consuming is a long problem. The project period is limited, the expansion water tanks are required to be filled for the first time in batch machine set installation, each expansion water tank needs at least 2-3 hours, the efficiency is low, and the project progress is seriously affected. The unit is generally installed in remote areas, and the subsequent fluid replacement if needed is difficult to be effectively completed.

3. The operation is not convenient. The expansion water tank is arranged at the uppermost part of the machine set and is higher than the height of a human body, and the position of the liquid level is observed when the expansion water tank climbs to the upper part of the machine set by means of a tool. When the water pump is closed, the condition of the back suction of the cooling liquid can occur, and because the liquid level fluctuates, the liquid level sensor can give an alarm repeatedly, and two people are required to cooperate to frequently start and stop the water pump until the cooling liquid is added to a proper position.
