Description

Technical Field

[0001] The utility model relates to the technical field of condensing equipment, in particular to a battery formation negative pressure module condenser. Background Art

[0002] With the rapid development of new energy electric vehicles, more and more car companies are joining the new energy vehicle market. At the same time, with the support of policies, new energy vehicles have increased significantly, which has prompted lithium-ion power batteries to enter a period of rapid development. During the production process of the battery, it is necessary to use battery charging and discharging equipment to charge and discharge the battery to realize the battery's chemical composition and activation. However, in the prior art, the battery produces a lot of gas during the formation process, which is prone to bloating and deformation. In response to the above problems, the current conventional method is to use a negative pressure formation method to solve the problem of gas generation during the battery formation process, that is, by adding a negative pressure cup to prevent the outflow of liquid and gas volatilization, but some of the gas still flows into the round manifold block. The gas lost in this process is also called liquid loss. The greater the liquid loss, the worse the formation effect. Utility Model Content

During operation, the negative pressure device generates negative pressure, and then connects with the corresponding negative pressure cup through the negative pressure cup connecting hose to generate negative pressure. The negative pressure cup absorbs the gas produced in the battery during the formation process by generating negative pressure. During the rising process, the gas generates heat exchange with the condensation device in the negative pressure cup connecting soft tube, condenses the gas into liquid and then flows back into the negative pressure cup cavity, and finally flows back into the battery, so as to achieve the effect of reducing the loss of battery liquid.

[0006] Preferably, an air intake baffle is installed in the condenser shell near the air inlet, and air intake dispersion holes are evenly opened on the air intake baffle. The concentrated air volume is dispersed into the interior of the condenser through the evenly arranged air intake dispersion holes, so that the cold air inside the condenser is more evenly distributed, thereby improving the condensation effect.

[0007] Preferably, a control valve is installed on the confluence negative pressure suction pipe to control the opening and closing of the negative pressure in the confluence block.

[0008] Preferably, a plug is installed on the left end of the manifold block to facilitate cleaning of the interior of the manifold block.

[0009] Preferably, an exhaust pipe joint is installed on the outer end of the exhaust pipe to facilitate the rapid external connection of the exhaust pipe.

[0010] Preferably, the negative pressure cup connecting hose is arranged in a spiral shape to increase the residence time of the gas in the negative pressure cup connecting hose. The longer the residence time, the more gas will be converted into liquid.

[0011] The utility model provides a battery formation negative pressure module condenser with the beneficial effect that: the battery formation negative pressure module condenser has a simple structure, reasonable design, and convenient operation, and can effectively reduce the amount of liquid loss during the battery formation process and improve the formation effect.
