Heat transfer unit especially for a motor vehicle rear evaporator receives flow from coolant circuit and lies within inner space separated from surroundings by closed wall with flange connection points

摘要

A heat transfer unit, especially for a motor vehicle rear evaporator, comprises at least one heat transfer unit (1) through which coolant from a cooling circuit flows via flow leads. The unit lies in an inner space separated from the surroundings by a closed wall (20) with further cooling circuits outside the inner space. The connection points of leads to the heat transfer unit are through flanges in the wall opening (21) outside the inner space.
