Heat exchange core, heat exchange structure and design method

Abstract

The application relates to the heat exchange field and discloses a heat exchange core body, a heat exchange structure and a design method, which comprise a curved surface dot matrix structure, a plurality of unit cells arranged in an array, cavities arranged in the unit cells, first flow channels formed by the cavities being communicated with each other, gaps formed between the outer walls of adjacent unit cells, and second flow channels formed by the gaps being communicated with each other; and a rod body arranged in the cavity of the corresponding unit cell and connected with the unit cell at both ends. The rod body and the curved surface dot matrix structure are matched with each other, the heat exchange core body structure is compact and reasonable, the strength reinforcement can be completed without greatly changing the original dot array arrangement form, the excellent fluid flow and heat exchange capacity of the curved surface dot matrix structure can be maintained, and the bearing stability of the curved surface dot matrix structure can be simultaneously improved, so that the two actual use demands of balancing high-efficiency heat dissipation and reliable bearing can be met, and the heat exchange equipment can be assembled and used under more severe working conditions.
