Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If thermal conductive adhesive is coated between the liquid cooling plate and the battery module to improve heat transfer effect, then heat dissipation efficiency is improved, but misalignment occurs leading to inconsistent adhesive thickness and uneven heat dissipation
Solution Approach 1:
The patent introduces a limiting member as an intermediary component between the battery module and liquid cooling plate. This limiting member defines a precise adhesive gap that ensures uniform adhesive thickness distribution, thereby maintaining consistent thermal contact while enabling accurate positioning during assembly
Solution Approach 2:
The limiting member is pre-installed on the liquid cooling plate before adhesive application. This preliminary action establishes the exact adhesive gap thickness in advance, guiding the adhesive to be applied uniformly within the defined gap, thus preventing misalignment and ensuring consistent thermal contact
2Temperature
If liquid cooling plate is installed on battery module bottom surface to achieve cooling, then heat management is improved, but misalignment causes excessive localized temperature differentials
Solution Approach 1:
The limiting member serves as a mediator that ensures proper alignment between the liquid cooling plate and battery module. By defining a uniform adhesive gap, it prevents misalignment that would otherwise cause localized temperature differentials, thereby ensuring reliable and uniform heat management across the entire battery module surface
Solution Approach 2:
The patent achieves homogeneous heat dissipation by using the limiting member to ensure uniform adhesive thickness distribution. This uniformity translates to consistent thermal contact between the cooling plate and battery module, eliminating localized temperature differentials and ensuring homogeneous temperature distribution across the battery module

Implementation Method 1
the liquid cooling plate is in thermal communication with the at least one battery module via the thermal conductive adhesive
Implementation Method 2
The liquid cooling plate is generally installed on a bottom surface of a battery module, and exchanges heat with the battery module by using a flowing coolant, so as to achieve cooling and heat dissipation of the battery module

AI summary
A battery pack. The battery pack includes at least one battery module, a liquid cooling plate, the liquid cooling plate, and at least one first limiting member. The liquid cooling plate is arranged on a bottom surface of the at least one battery module. Each of the at least one first limiting member is arranged between the liquid cooling plate and a bottom surface of each of the at least one battery module, so that an adhesive gap with a uniform thickness is defined between the liquid cooling plate and the bottom surface of each of the at least one battery module. A thermal conductive adhesive is applied in the adhesive gap, and the liquid cooling plate is in thermal communication with the at least one battery module via the thermal conductive adhesive.
