Abstract
A liquid cooling device includes a heat-dissipating unit (1) and a heat-absorbing unit (2). The heat-dissipating unit (1) connects with the heat-absorbing unit (2) by an inlet pipe (4) and an outlet pipe (3) to form a closed circulation loop. The heat-dissipating unit (1) includes a base (10), a tank (20), a heat-dissipating body (30) beside the tank (20) and a cover (40), which are assembled together as a single unit. A pump (23) is placed in the tank (20) and operated to pump liquid coolant to flow in the circulation loop. During flowing through the base (10) and the cover (40), the liquid coolant transfers heat to the heat-dissipating body (30).
Claims17
A liquid cooling device comprising:
- a heat-absorbing unit for thermally contacting with a heat generating electronic component;
- a heat-dissipating body defining an air flow passage therein;
- a fan mounted to the heat dissipating body for forming a forced air flow flowing through the air flow passage;
- a liquid coolant circulation loop comprising a first segment extending at a first side of the heat-dissipating body, a second segment extending at a second side of the heat-dissipating body opposite the first side, and a third segment connecting the first and second segments and extending at a third side of the heat-dissipating body between the first and second sides;
- a pair of pipes connecting the third segment of the circulation loop to the heat-absorbing unit for liquid flowing between the circulation loop and the heat-absorbing unit;
- and
- a pump arranged in the loop to drive a circulation of liquid in the liquid cooling device from the heat-absorbing unit to the circulation loop and back to the heat-absorbing unit, wherein the heat dissipating body, the fan and the circulation loop are built as a single unit.
A liquid cooling device comprising:
- a heat-absorbing unit;
- a heat-dissipating body;
- a base defining a first groove;
- a cover defining a second groove;
- a tank defining a first channel communicating with the first groove of the base, a second channel communicating with the second groove of the cover and isolated from the first channel, a third channel isolated from the first and second channels and communicating with the first groove and the second groove;
- a pair of pipes connecting the first channel and the second channel to the heat-absorbing unit;
- and
- a pump positioned in the tank to drive a circulation of liquid in the liquid cooling device from the heat-absorbing unit, the tank, the first groove, the second groove, the tank and back to the heat-absorbing unit.
A liquid cooling device comprising:
- a heat-absorbing unit adapted for thermally contacting with a heat generating electronic component;
- liquid coolant;
- and
- a heat dissipating unit, comprising:
- a tank fluidically connecting with the heat absorbing unit;
- a heat-dissipating body secured to a side of the tank;
- a cover mounted to tops of the tank and the heat-dissipating body;
- a base mounted to bottoms of the tank and the heat-dissipating body;
- and
- a pump mounted in the tank, wherein when the pump operates, the liquid coolant flows in circulation according to a sequence:
- the heat absorbing unit, the tank, the base, the tank, the cover, the tank and finally back to the heat absorbing unit.
