A cooling fan faces toward the fin structure of the radiator.

Abstract: A heat dissipating device includes a heat sink, a pump connected to the heat sink, and a radiator connected to the heat sink and the pump. The radiator includes spaced apart first and second side tanks. The second side tank defines an inner space therein and is formed with a coolant-refilling opening in fluid communication with the inner space. The radiator further includes a cap mounted removably on the second side tank for closing sealingly the coolant-refilling opening, a plurality of conduits interconnecting and in fluid communication with the first and second side tanks, and a fin structure disposed between the first and second side tanks and connected to the first and second side tanks and the conduits.

Abstract: A heat dissipating device is adapted to be connected to a heat sink and includes: a radiator including first and second side tanks adapted to store a coolant therein, a fin structure disposed between and interconnecting the first and second side tanks, and connecting conduits connected to the fin structure and interconnecting and in fluid communication with the first and second side tanks, the radiator further including a buffer tank that is mounted on and that is in fluid communication with the first side tank and that has a coolant outlet adapted to be connected to the heat sink, the second side tank having a coolant inlet adapted to be connected to the heat sink; and a pump mounted directly on the buffer tank.

Abstract: A liquid cooled heat sink includes: a casing having a liquid inlet and a liquid outlet; and a fin unit provided in the casing and having a wave-like structure of a multi-fold sheet that defines a plurality of fluid paths which are aligned in series in a transverse direction relative to the fluid paths. The liquid inlet of the casing is in fluid communication with the liquid outlet of the casing through the fluid paths.

Abstract: A heat dissipating device includes: a plurality of conduits stacked one above the other, each of the conduits including upper and lower halves, each including a base wall with two opposite end portions and an intermediate portion, a flange that extends from the base wall and that cooperates with the base wall to define a chamber half therebetween, and two protrusions that protrude respectively and outwardly of the chamber half from the end portions of the base wall, the protrusions being formed with a through-hole and being connected respectively to the protrusions of adjacent upper and lower halves of adjacent conduits; and a plurality of heat dissipating fin units, each is disposed between and is in contact with two adjacent ones of the conduits.

Abstract: A heat dissipating unit includes: a housing defining an inner space therein, a fluid inlet in fluid communication with the inner space and adapted to receive a coolant therein, and a fluid outlet in fluid communication with the inner space and adapted to discharge the coolant therefrom; a plurality of partitioning plates disposed in the inner space so as to divide the inner space into a plurality of compartments that are connected to each other in an end-to-end manner such that the compartments cooperate to form a continuous tortuous channel with two ends respectively connected to the fluid inlet and the fluid outlet; and a plurality of heat dissipating fins that are formed in each of the compartments.
