Heat exchanger for an electronic control unit

A heat exchanger comprising:

• a housing;
• a first tube including
• a first flat plate and a first shaped plate connected to each other to form a first tube channel extending along a first tube extension axis,
• a first tube inlet and a first tube outlet interconnected by the first tube channel, a second tube including
• a second flat plate and a second shaped plate connected to each other to form a second tube channel extending along a second tube extension axis,
• a second tube inlet and a second tube outlet interconnected by the second tube channel,
• the first tube and the second tube being fixed to each other by an interconnector, the interconnector communicating fluidically the first tube inlet with the second tube inlet and communicating fluidically the first tube outlet with the second tube outlet, wherein the interconnector includes an external inlet and an external outlet,
• wherein the housing has an interconnector cut-out at least partially enveloping the interconnector;
• wherein the first tube channel forms a first primary arm and a second primary arm extending parallel to each other along the first tube extension axis, wherein the first primary arm includes a first primary inner fin and the second primary arm includes a second primary inner fin.
