8. The multi-stage intercooler water circuit isolating assembly of claim 7, wherein the second housing abutment portion includes a second sealing end protruding from the second body portion in a second direction, the second chip abutment surface having a second arcuate surface section extending from the second body portion to the second sealing end such that a width of the second sealing end in the length direction of the second body portion gradually decreases as the second arcuate surface section extends away from the second body portion.

9. A multi-stage intercooler comprising a housing, a core and the multi-stage intercooler water circuit spacer of any one of claims 1-6.

10. The multi-stage intercooler of claim 9, wherein the multi-stage intercooler water path partition comprises a frame unit including a frame portion and a passage portion through which each chip of the core passes, the passage portion being enclosed by an inner side edge of the frame portion, both of the first housing abutment portions of the main water path partition unit being fixed to the inner side edge;

the width of the frame in the third direction is greater than that of the main waterway isolation unit, so that a right-angle accommodating part is formed between the inner side edge of the frame and the main waterway isolation unit, and one end part of the shell is matched with the accommodating part, so that the inner side edge of the frame at the end part is attached to the main waterway isolation unit.

11. A multi-stage intercooler characterized by comprising a housing, a core and the multi-stage intercooler water path isolation assembly of claim 7 or 8, a side water path being formed between the housing and the core, the side water path isolation being installed in the side water path.
