Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2020/116903
Kind Code:
A1
Abstract:
The present invention relates to a heat exchanger including a plurality of fluid channel plates laminated on each other to form a cooling water fluid channel through which cooling water flows and an air fluid channel through which air flows, wherein the fluid channel plates have a cooling water inlet hole through which the cooling water is introduced and a cooling water outlet hole through which the cooling water is discharged, and the cooling water inlet hole and the cooling water outlet hole are spaced apart from each other, and beads, which block the flow of the cooling water, protrude between the cooling water inlet hole and the cooling water outlet hole, wherein the beads are arranged to surround the periphery of the cooling water inlet hole and the cooling water outlet hole, and are spaced apart from each other such that flow resistance of the cooling water decreases as a flow length of the cooling water increases, so that, flow distribution of the cooling water can be uniformized by the beads protruding to guide the flow of the cooling water on the fluid channel plates, thereby improving cooling efficiency of the heat exchanger.
