AI Technical Summary

Technical Problem

The existing cooling water nozzles for new energy batteries have insufficient sealing performance, and are prone to gaps under vibration and thermal shock, leading to coolant leakage. They also have weak resistance to loosening, increasing assembly complexity.

Method used

Multiple O-rings and locking mechanisms are used to achieve a tight connection between the water nozzle body and the cooling pipe. Combined with the design of the internal threaded sleeve and the tapered limiting tube, the sealing performance and vibration resistance are enhanced, and pressure relief is provided through the water outlet in case of abnormal pressure.

Benefits of technology

It achieves a highly sealed and vibration-resistant connection, preventing coolant leakage, reducing assembly complexity, and protecting the water nozzle body by releasing pressure in case of abnormal pressure, preventing rupture.

Abstract

The utility model mainly relates to new energy battery cooling technical field, concretely relates to a sealed new energy battery cooling water nozzle, including the water nozzle body, the water nozzle body water inlet end is sleeved in the outer wall of cooling pipe and realizes the lock through the locking mechanism, the inner wall of water nozzle body is equipped with a plurality of first O type sealing rings that are equidistantly embedded along its axial direction, and the first O type sealing ring is used for clamping into the annular sealing groove that is correspondingly set in the outer wall of cooling pipe;The locking mechanism comprises: a limiting ring fixedly connected to the water inlet end of the water nozzle body;An outer thread sleeve with one end fixedly connected to the limiting ring;A plurality of elastic locking pieces equidistantly distributed in the end away from the limiting ring of the outer thread sleeve in the circumferential direction;An inner thread sleeve is screwed with the outer thread sleeve;A conical limiting tube is integrally formed at one end of the inner thread sleeve and has a conical inner wall;When the inner thread sleeve is screwed into the outer thread sleeve, the conical limiting tube moves axially to compress the outer wall of the elastic locking piece, forcing it to elastically deform radially inward to tightly hold the outer wall of the cooling pipe.
