A study on the optimal design for preventing thermal deformation over the oven door

An oven is a device that generates high heat by using radiation and convection to heat food. Due to the high heat generated when the oven was operating, the door is deformed and a gap is created, and heat leaks through the gap. In this study, in order to prevent heat loss due to deformation of the oven, after we established an analysis technique that reflects the actual operating conditions of the oven in finite element analysis (FEA), an optimal shape that could prevent thermal deformation of the oven door was designed. The validity of the analysis was reviewed by comparing the results of the newly proposed finite element analysis with those of the actual measured deformation of the door. Also, the door shape that can minimize thermal deformation was optimally designed through analyzing the design parameters to be influenced to thermal deformation, using the response surface method.
