Compound type heat exchanger

A compound type heat exchanger comprising:

• a first heat exchanger having a pair of tanks arranged a certain distance apart from each other and a core part having a plurality of tubes between the pair of tanks:
• and
• a second heat exchanger, wherein
• at least one of the pair of tanks includes a plurality of divided bodies that is divided and connected along a longitudinal direction of the at least one of the pair of tanks,
• one of the plurality of divided bodies is provided with an accommodation portion that has an opening portion and projects outwardly to be connected with the one of the plurality of divided bodies so that a flowing medium of the first heat exchanger can flow to the one of the plurality of divided bodies, wherein
• the second heat exchanger is arranged in the accommodation portion,
• the accommodation portion is provided with a connection port as a gateway of the flowing medium of the first heat exchanger,
• heat is exchanged between the flowing medium of the first heat exchanger that flows through the accommodation portion and a flowing medium of the second heat exchanger, and
• the second heat exchanger is positioned through the opening portion and detachably fixed to the accommodation portion from an exterior side of the accommodation portion.
