Abstract

An electronic device includes an outer casing (10) with a heating unit (31), and a cooler (40) which is arranged in the outer casing (10) and is used for cooling the heating unit (31). The cooler (40) includes the following components: (i) a heat dissipating part (50); (ii) a circulating path (60) thermally coupled with the heat dissipating part (50); and (iii) a pump (100) which is coupled with the circulating path (60) and the heating unit (31), and the pump (100) uses the circulating path (60) for circulating the coolant. The pump (100) includes the following components: (i) a pump casing (101) which comprises a heat-absorbing surface (120) thermally coupled with the heating unit (31); (ii) a pump chamber (118) used for compressing the coolant; (iii) a rotary unit (102) which is in the pump chamber (118) and is used for conveying the coolant in and out the circulating path (60); (iv) an electric motor (103) which is coupled with the rotary unit (102) and is used for rotating the rotary unit (102) to convey the coolant; and (v) three installing parts (151, 152 and 153) which is used for fixing the pump (100) on the outer casing (10).

Description

technical field [0001] Embodiments of the present invention relate to a liquid cooling system, and more particularly, to a pump in a liquid cooling system that utilizes a liquid coolant to cool a heat-generating unit, such as a central processing unit (CPU). Background technique [0002] As processing speed and versatility increase, CPUs may generate a significant amount of heat (ie, operating heat) while operating, and thus may require cooling to maintain stable operations. [0003] Use a heat sink as a cooler to cool down the CPU. The heat sink may include an electric fan for blowing cold air onto the CPU, and a casing for accommodating the electric fan. The housing has a heat sink surface thermally coupled with the heat generating unit, and at least three mounting portions. The heat sink is fixed such that the heat absorbing surface and the CPU are thermally coupled to each other. One such heat sink is disclosed in Japanese Patent Application Laid-Open No. 2002-353670....
