Abstract

This invention discloses a liquid cooling plate with nested flow channels, comprising an upper cooling plate, a lower cooling plate spaced vertically above and below the upper cooling plate, and a flow channel plate disposed between the upper and lower cooling plates. The flow channel plate is stamped with nested first and second flow channel grooves. One of the upper or lower end faces of the flow channel plate has the first flow channel groove, and the other has the second flow channel groove. The upper and lower cooling plates are respectively attached to the upper and lower end faces of the flow channel plate to seal the first and second flow channel grooves, forming the first and second flow channels respectively. Coolant flows within both the first and second flow channels. This invention's liquid cooling plate, through its nested flow channel design, not only achieves cooling on both upper and lower planes, but also ensures that the two flow channels are independent and do not interfere with each other. Furthermore, this invention also provides a battery module and battery pack incorporating this liquid cooling plate.
