Deionizer-radiatorcapable of being disassembled quickly

Abstract

The invention discloses a deionizer-radiator capable of being disassembled quickly. The deionizer-radiator is characterized in that: a deionizer is detachably installed on the outer side of a radiator, inserting pipes are arranged at the inlet end and the outlet end of the deionizer, communicating openings are formed in the ends of the inserting pipes, inserting openings corresponding to the inserting pipes are formed in the radiator, springs are arranged on the radiator, the inserting openings are formed in a water chamber shell body of the radiator and communicated with a water chamber, a sealing ring is arranged on the inner wall of each inserting opening, the springs are located in the water chamber shell body, one ends of the springs are installed on an internal component of the waterchamber shell body, a plugging block is installed at the other end of each spring, and a sealing gasket is arranged on one side of the plugging block close to each inserting opening; and when the deionizer is not installed, the springs compress the sealing gaskets on the inner sides of the inserting openings in a sealed mode through the plugging blocks, when the deionizer is installed in place, the inserting pipes stretch into the corresponding inserting openings in a sealed mode through the sealing rings and then push the sealing gaskets and the plugging blocks to overcome spring force to leave the inner sides of the inserting openings, the interior of the water chamber communicates with the interior of the inserting pipes through communicating openings, and the communicating openings are formed in the inner sides of the sealing positions of the inserting pipes and the sealing rings. The mounting space is saved, mounting and dismounting are rapid, and liquid leakage is avoided.

Description

technical field [0001] The invention belongs to the field of fuel cells, in particular to a deionizer-radiator that can be quickly disassembled. Background technique [0002] When the coolant runs inside the fuel cell for a period of time, a large number of ions will be generated, which will affect the insulation performance of the proton exchange membrane and reduce the energy conversion efficiency of the fuel cell. Slight electrolysis produces a mixed gas of hydrogen and oxygen, which affects the safe operation of the battery. Therefore, it is necessary to use a deionizer to continuously absorb the free ions in the cooling liquid of the fuel cell. [0003] After the deionizer continues to absorb ions, its service life will gradually decrease, and it needs to be replaced according to time or mileage. At present, most ionizers are integrated on the body of the fuel cell, forming a parallel circuit with the fuel cell coolant inlet and outlet circuits, which can control the ...

AI Technical Summary

Problems solved by technology

At present, most ionizers are integrated on the body of the fuel cell, forming a parallel circuit with the fuel cell coolant inlet and outlet circuits, which can control the flow into the deionizer, but the passenger car cabin is small, and the fuel cell installation The boundary is large, so that the fuel cell is arranged behind the engine room of the passenger car, and the operable space is narrow. It is necessary to remove the surrounding parts and discharge the coolant in the cooling circuit at the same time, which makes replacement and maintenance more troublesome.

Although there are a few deionizers that can be disassembled, the operation is complicated and the disassembly process is not short
