Heat exchanger

Abstract

A heat exchanger includes a body. Both sides of the body are provided with a first flowing path set and a second flowing path set. The first flowing path set and the second flowing path set are provided with a plurality of flow-disturbing portions on both sides of the body respectively. The body is provided with an inlet and an outlet in communication with the first flowing path set and the second flowing path set. A working fluid circulates in the first flowing path set and the second flowing path set. The flow-disturbing portions make the working fluid to generate separated eddies to increase the strength of turbulent flow and to improve the heat-conducting efficiency of the heat exchanger greatly.
