Technical Field

The invention belongs to the technical field of coolant deionization, and particularly relates to a full-life-cycle deionized resin tank.

Background

Currently, the current state of the art commonly used in the industry is such that: a fuel cell vehicle is a new energy vehicle using hydrogen energy, and a cooling system maintains the temperature of a fuel cell at an appropriate temperature while the fuel cell vehicle is operating. However, the ion conductivity of the coolant increases due to the ion deposition in the fuel cell stack and the cooling line, and short-circuiting of the stack is likely to occur. Therefore, fuel cell vehicles require a deionizing resin tank to reduce the ionic conductivity of the cooling circuit. The traditional deionization tank for the vehicle generally adopts a straight cylinder structure, and anion and cation resin is uniformly mixed and then directly filled into a tank body. The diameter of the anion and cation resin is about 100 μm, and the diameter of the anion and cation resin is reduced to improve the adsorption capacity. The anion and cation resin with small diameter is accumulated in the tank body, the accumulation density is high, and the liquid is discharged after passing through all the resin from the bottom of the tank body, so the fluid resistance is high. In addition, because the adsorption capacity of the ion resin in the tank body is limited, the ion resin tank needs to be replaced after the ion resin tank reaches the service life for a long time.

In summary, the problems of the prior art are as follows:

(1) the service life of the commonly used deionized resin tank is limited, and the deionized resin tank needs to be replaced frequently in the life cycle of the automobile

(2) In the traditional deionization tank, the resin is mixed and directly filled into the tank body, and the liquid is discharged after passing through all the resin from the bottom of the tank body, so that the fluid resistance is high.

The difficulty of solving the technical problems is as follows:

because the adsorption capacity of the anion and cation resin is limited, the ion resin is saturated in adsorption in the long-term use process, and the service life of the deionized resin tank is reached. The diameter of the anion and cation resin is about 100 μm, and the diameter of the anion and cation resin is reduced to improve the adsorption capacity. The anion and cation resin with small diameter is accumulated in the tank body, and the accumulation density is high, so that the resistance of liquid flow is high.

The significance of solving the technical problems is as follows:

the service life of the ionic resin tank is prolonged, and the use of the automobile in the whole life cycle is met, so that the quality and the safety of the automobile are guaranteed. The resistance of the ion tank is reduced, the deionization effect is increased, and the energy consumption of the water pump is reduced.
