1. A heat exchanger, comprising a core body, wherein the core body comprises a first plate sheet and a second plate sheet which are stacked layer by layer, the core body has a first fluid channel and a second fluid channel which are isolated from each other, the first fluid channel comprises a first pore passage and a second pore passage located on the same side in a width direction of the core body, the first fluid channel further comprises a first inter-plate channel located between the first plate sheet and the second plate sheet and corresponding to the first pore passage and the second pore passage, at least one of the first plate sheet and the second plate sheet comprises a first isolation portion configured to separate the first inter-plate channel into a first sub inter-plate channel and a second sub inter-plate channel, the first sub inter-plate channel is in communication with the first pore passage, and the second sub inter-plate channel is in communication with the second pore passage,
wherein the core body further comprises a first blocking portion, the first pore passage comprises a first sub-pore passage and a second sub-pore passage, the first sub-pore passage and the second sub-pore passage are located on two sides of the first blocking portion, the heat exchanger further comprises an end plate and an adapter seat, the adapter seat is fixed to the end plate,
wherein the adapter seat is provided with a first port and a second port located on the same side in a thickness direction of the core body, one of the first sub-pore passage and the second sub-pore passage is in communication with the first port, and the other of the first sub-pore passage and the second sub-pore passage is in communication with the second port,
wherein the first blocking portion has a support hole, a diameter of the support hole is smaller than a diameter of the first pore passage; the heat exchanger further comprises an inner pipe, a part of the inner pipe is configured to extend into the first pore passage, the inner pipe is passed through the support hole, and an outer wall of the inner pipe is sealingly connected with an inner wall of the support hole; the inner pipe is configured to communicate the first port with the second sub-pore passage, the first inter-plate channel and the second pore passage are configured to communicate the second sub-pore passage with the first sub-pore passage, and the second port is in communication with the first sub-pore passage,
the end plate comprises a through hole, the through hole is aligned with the first pore passage, the inner pipe is passed through the through hole, an annular channel is formed between an inner wall of the through hole and the outer wall of the inner pipe, the annular channel is configured to communicate the second port with the first sub-pore passage, a part of the end plate opposite to the second pore passage blocks a corresponding end of the second pore passage,
a flow groove is provided on a side of the adapter seat opposite to the end plate, the flow groove is configured to communicate the second port with the annular channel, the adapter seat is further provided with an annular boss, the boss is configured to extend from an inner wall of the first port toward the central axis of the first port, at least a part of the boss is a part of a corresponding bottom wall of the flow groove, the top of the inner pipe is provided with a flange portion protruding outward, and the flange portion is sealingly connected with the boss.
