Abstract:
A lamination type heat exchanger comprising:a pair of thin plates joined to form a fluid passage for exchanging heat between fluid flowing in the fluid passage in a longitudinal direction of the pair of thin plates and air flowing outside of the fluid passage;an inner fin disposed in the fluid passage and dividing the fluid passage into a plurality of subpassages which are arranged in an air flow direction in which the air flows, the plurality of subpassages including an upstream side subpassage and a downstream side subpassage which is provided on a downstream side more than the upstream side subpassage in the air flow direction;an inlet tank portion integrally provided at a first end of the pair of thin plates in the longitudinal direction and communicating with the plurality of subpassages for distributing the fluid into the plurality of subpassages;an outlet tank portion integrally provided at a second end of the pair of thin plates on an opposite side of the first end and communicating with the plurality of subpassages for collecting the fluid from the plurality of subpassages; anda fluid distribution controlling portion provided between the inlet tank portion and the plurality of subpassages for controlling first and second amounts of the fluid respectively distributed into the upstream side and downstream side subpassages such that the second amount of the fluid distributed into the downstream side subpassage is smaller than the first amount of the fluid distributed into the upstream side subpassage.
