Liquid cooling heat dissipation device
A liquid cooling heat dissipation device for a coolant flowing in one direction has a bottom seat, a baffle, and a cover. The bottom seat has a plurality of heat dissipation members. A plurality of flow channels is formed between the heat dissipation members. The baffle is arranged on the bottom seat and defines a plurality of slot groups arranged in parallel. The slot groups are communicated to the flow channels. The cover is arranged on the baffle and defines a cavity and a through hole. The cavity is concave from a side of the cover facing the baffle and communicated to the slot groups to form a chamber. Two opposite sides of the chamber are respectively communicated to the through hole and the slot groups. The coolant enters the chamber for confluence from the flow channels through the slot groups, and then exits the chamber through the through hole.
