Abstract
Background: In the manufacturing process of lithium batteries for new energy vehicles, silica
gel plates shall be used as heating and thermal insulation. This paper takes four groups of silica gel
heating plates with different specifications as the research object to predict the temperature distribution
of silica gel plates and provide theoretical references for the manufacturing engineering of silica gel
heating plates.
Objective: Combined with the heat transfer theory, the temperature distribution of silica gel heating
plate is predicted by simulation calculation, and the feasibility of this method is verified by experiments,
which provide references for the manufacturing engineering of silica gel heating plate.
Methods: This article takes four groups of silica gel plates with different specifications as the research
objects, and 30 temperature measurement points are collected. The simulation results are compared with
the experimental results to verify the method’s feasibility.
Results: The average error between the experimental and simulation results was ± 2.6°C, which was in
line with the expected effect of silica gel plates. This paper’s research process and method can provide
theoretical references for the manufacturing engineering of silica gel heating plates.
Conclusion: Taking the silica gel heating plate provided by the factory as the research object, according
to the heat transfer theory, the thermal conductivity equation of the silica gel plate was established,
which provided a theoretical model for simulation analysis. The experimental results show that the average
error between the simulation and experimental results is ±2.6°C, which is in line with the empirical
expectation, and the method is feasible. This paper’s research process and practice can provide theoretical
reference for the manufacturing engineering of silica gel heating plate.
