Indirect charge-air cooler

An internal combustion engine, comprising:

• a heat exchanger configured as a charge-air cooler, the heat exchanger including:
• a first duct system including a plurality of pipes for a first fluid which flows in a first flow direction;
• a second duct system disposed between the plurality of pipes for a second fluid to flow through in a second flow direction, the second duct system fluidically separated from the first duct system;
• a collector fluidically separated from the second duct system, the collector including a base part and a box part defining a collecting chamber fluidically connected to at least one pipe of the plurality of pipes;
• the base part of the collector including at least one opening connected to the at least one pipe such that the collecting chamber is fluidically separated from the second duct system;
• at least two opposite side parts for fluidic delimitation of the second duct system, wherein the plurality of pipes are arranged between the at least two side parts and the base part transitions into at least one side part of the at least two side parts in a surface-flush manner;
• the box part of the collector engaging via a first contact surface against at least one side part of the at least two side parts;
• the box part and the at least one side part are cohesively joined to one another via the first contact surface;
• and
• at least one frame part coupled in at least one of a non-positively locking connection and a cohesive connection to at least one of a respective outer edge of the at least two side parts, a respective outer edge of the base part, and a respective outer edge of the box part.
