The topic of this thesis is heat transfer in the complex structure of a hot-wall evaporator, used in household refrigerators. An analytical model for describing temperature, heat flow and thermal resistance distribution in a hot wall evaporator structure, of a household refrigerator, is presented in the first part of this thesis. Analytical results are compared with a numerical simulation. Ideas and results of possible design improvements, for increased heat transfer in the evaporator structure, are presented in the second part of this thesis. They are evaluated by their influence on heat flow increase, technical feasibility and costs.
