Abstract: The present disclosure relates to heat dissipation apparatuses. In an example, a node includes a structural module, a circuit board, a liquid pipe, and a liquid leakage monitoring apparatus. The circuit board is securely mounted on the structural module, and an electronic component including a chip is disposed on the circuit board. The liquid pipe is disposed on the circuit board, and is configured to dissipate heat for the electronic component on the circuit board. The liquid leakage monitoring apparatus includes a drainage pipe sleeved outside the liquid pipe. There is a specific gap between the drainage pipe and the liquid pipe. In response to at least that leakage occurs in the liquid pipe, leaked coolant flows in the drainage pipe.

Abstract: An air baffle component includes an air baffle rotationally connected to a housing of a device chassis having a module insertion port. The air baffle component also includes a level-1 elastic component. The air baffle component further includes a level-2 elastic component. The air baffle component additionally includes a connecting rod. The connecting rod includes a force-bearing rod rotationally connected to the housing of the device chassis between the air baffle and the module insertion port. The connecting rod also includes a pull rod connected to the force-bearing rode. The connecting rod further includes a baffle column on the pull rod. The level-1 elastic component provides a first elastic force for the force-bearing rod, so that the baffle column is caused to abut against a surface of the air baffle opposite to the module insertion port. The level-2 elastic component provides a second elastic force for the air baffle.
