Abstract: A heat exchange device includes a core and a housing. The core includes a first collecting part and a second collecting part, and a flat tube part is provided between the two. The flat tube part includes a first flat tube group and a second flat tube group. The first collecting part includes first and second collecting portions, and a separator is formed between the two. Each flat tube of the first flat tube group is communicated with the collecting cavity of the first collecting portion. The collecting cavity of the first collecting portion is communicated with the collecting cavity of the second collecting portion through the first flat tube group, the collecting cavity of the second collecting part, and the second flat tube group.

Abstract: A heat exchanger is provided according to the present application, which includes a core body. The core body includes a first sheet and a second sheet that are arranged in a stacked manner. The core body is provided with a first fluid channel and a second fluid channel that are isolated from one another. The first fluid channel includes a first pore channel and a second pore channel. The core body further includes a first blocking part. The first pore channel includes a first sub-pore channel and a second sub-pore channel. The heat exchanger further includes a first connection port and a second connection port that are located on the same side of the core body in the thickness direction thereof.

Abstract: A heat exchanger comprising a housing and a core body accommodated in the housing. The housing comprises a first body and a second body. The first body is a metal material. The second body is a plastic material. The first body and the second body are connected to each other so as to form a first cavity. The core body is accommodated in the first cavity. The core body is fixedly connected to the first body. The core body comprises multiple heat exchange tubes. A first fluid channel is formed between the heat exchange tubes. A second fluid channel is formed in the heat exchange tube. The heat exchanger further comprises a connecting block. The connecting block is fixed to the first body, and the connecting block is located outside the first cavity. The connecting block is provided with a first flow-through hole.

Abstract: A heat exchanger is provided, including a heat exchanger core. The heat exchanger core at least includes a first core part, a second core part and a third core part which are stacked. The first core part, the second core part and the third core part are formed by stacking plates. The third core part is located between the first core part and the second core part. The first core part is in the form of unilateral flow. The second core part is in the form of diagonal flow. The third core part can realize transformation of flow channel forms of the first core part and the second core part, and is stacked with the first core part and the second core part, and thus the heat exchange efficiency is good.
