Discrepancy in evaluating heat flux on thermally insulated boundary

Hello for the savior!
I tried solving conjugate heat transfer problem with laminar flow where the outer boundaries are given as thermal insulation boundary condition (heat flux across the boundary should be zero). when I evaluate the Normal conductive heat flux (ht.ndflux), Normal total energy flux (ht.nteflux) and Normal total heat flux (ht.ntflux) on the insulated boundary none of them were zero. Also the isothermal contours are not perpendicular to insulated boudaries.
What are the reasons for such situations?
I solved this problem in COMSOL 5.2a and I used normal mesh (physics controlled) I am also attaching the geometry file here for reference
Thanks much
