Abstract

A coolant guiding structure can guide a coolant to a plurality of electronic components spaced from each other. The coolant guiding structure includes a housing, a plurality of first baffles, a plurality of second baffles, and a plurality of spoiler assemblies. The housing includes a liquid inlet and a liquid outlet. The liquid inlet can introduce the coolant into the housing, and the liquid outlet can discharge the coolant out of the housing. A first opening is formed between two adjacent first baffles, a second opening is formed between two adjacent second baffles, and a guide channel is formed between the first opening and the second opening. Each first baffle and a corresponding second baffle can accommodate one electronic component therebetween. At least two spoiler assemblies are disposed in the guide channel. The present disclosure further provides an electronic assembly.
