Description
Technical field
The present invention relates to a kind of detection method of electrokinetic cell water cooling pole air-tightness, belong to power battery technology field.
Background technology
Pole is the important spare part of battery, mainly plays input, output current, when have high current input or output When, pole produces heat, causes battery temp to raise, influences the life of storage battery, it is necessary to takes cooling measure to pole.It is dynamic Power battery typically uses water cooling pole, has cooling line inside pole, directly pole is cooled down, improves cooling effect. Water cooling pole belongs to cast member, is to form one layer of metal of casting outside the copper core body with refrigerating function.Due to copper and lead Shrinkage factor when heated is different, peeling easily occurs between copper core body and metal after casting.If metal exist micro-crack, The defects of stomata, after assembled battery, acid solution prolongs micro-crack infiltration, under chemistry and electrochemical action, by copper core body corrosion failure, Influence service lifetime of accumulator and the security used.Therefore, it is necessary to the air-tightness of water cooling pole is detected.
The content of the invention
It is an object of the invention to provide a kind of detection method of electrokinetic cell water cooling pole air-tightness, its design science is closed Reason, simple and convenient, efficiency high, extends the service life of battery, improves safety coefficient during use.
The detection method of electrokinetic cell water cooling pole air-tightness of the present invention, it is that more water cooling poles are put into water-bath In groove, connected between water cooling pole using U-shaped connecting tube, quick-release connector is empty with compression by the water nozzle of first water cooling pole Air pipe is connected, and the water nozzle of last root water cooling pole is sealed with seal nipple, is passed through 0.4~0.6MPa compressed airs, pressurize 3-5min。
Preferably, the quantity of water cooling pole is 2-4 roots, in this case, detection efficiency highest.
Pressure gauge is housed on the compressed air line.
The quick-release connector maximum extension diameter matches with external diameter at water cooling pole water nozzle bayonet socket.
The U-shaped connection bore is interference fitted with diameter at water cooling pole water nozzle bayonet socket, the material used in U-shaped connecting tube With certain elasticity, and certain pressure can be born.
The seal nipple one end open, match with internal thread, and with water cooling pole water nozzle external screw thread.
The present invention utilizes quick-release connector, U-shaped connecting tube and seal nipple, sealing pipeline is formed with water cooling pole, by logical Enter the compressed air of certain pressure, liquid level state in pressure value and water bath is observed, to judge electrokinetic cell water cooling pole Air-tightness, then judge whether the castability of water cooling pole is qualified.Described quick-release connector coordinates with water cooling pole water nozzle, energy Enough fast and easy grafting；U-shaped connecting tube connects multiple water cooling poles, improves detection efficiency；Sealing device is by the other end Sealing, prevents the pressure leakages in pressure maintaining period.
The present invention compared with prior art, has the advantages that：
The design of the invention is scientific and reasonable, simple and convenient, efficiency high, extends the service life of battery, improves Safety coefficient during use.
