Abstract
A heat exchanger includes at least two plate bodies stacked with each other and at least one connecting sheet. Each of the at least two plate bodies is provided with a plurality of micro-passages. The at least one connecting sheet is arranged between adjacent plate bodies of the at least two plate bodies. A solder is disposed on each of two opposite sides of the at least one connecting sheet, and the solder is configured to weld and fix the at least one connecting sheet with the adjacent plate bodies of the at least two plate bodies.
Claims20
A heat exchanger, comprising:
- at least two plate bodies stacked with each other, wherein each of the at least two plate bodies is provided with a plurality of micro-passages and each plate body comprises a body part and a connecting part, wherein a first end of the connecting part is connected to the body part;
- at least one collecting tube, wherein the collecting tube has at least two insertion holes formed in a tube wall of the collecting tube, a second end of the connecting part of the plate body faces the insertion holes, a first distance is defined between two adjacent insertion holes defined in the tube, a second distance is defined between the body parts of two adjacent plate bodies, and the first distance is greater than the second distance;
- and
- at least one connecting sheet, arranged between the body parts of adjacent plate bodies of the at least two plate bodies, wherein each of two opposite sides of the at least one connecting sheet disposed with a solder, and the solder is configured to weld and fix the at least one connecting sheet with the body parts of the adjacent plate bodies of the at least two plate bodies.
