Liquid cooling system, and electronic apparatus having the same therein

Abstract

In a cooling system of liquid type, dissolving a problem upon starting when applying a centrifugal pump therein, and being freely applicable into various kinds of electronic apparatuses, easily, for cooling a CPU in need of cooling thereof, which is mounted within a housing 100, the system comprises: a cooling jacket 50, a radiator 60 and a circulation pump, wherein the circulation pump is built up with a centrifugal pump, in which a rotor 730 having a plural number of blades formed in a centrifugal manner, a pump chamber 741 receiving the rotor in an inside thereof, and a field coil 712 of an electric motor for driving the rotor rotationally are formed into one body, and the pump chamber is disposed to located below the electric motor, thereby achieving the structure so that a liquid coolant fills up the pump chamber when stopping, in spite of the disposition of the circulation pump, thereby dissolving the problem of idling when starting.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to an electronic apparatus, such as, a personal computer, being so-called a desktop-type or a notebook-type, or a server, etc., and in particular, it relates to a liquid cooling system being able to cool down a heat-generation element mounted within an inside thereof, such as, a semiconductor integrated element, effectively with an aid of a liquid refrigerant or coolant, and further an electronic apparatus having such the liquid cooling system therein. [0002] In order to maintain a normal operation thereof, cooling is necessary for the heat-generation element, such as, the semiconductor IC element, being mounted within an electronic apparatus, including a personal computer, of called the desktop-type or the notebook-type, as well as, a server, etc., and in particular, the heat-generation element, such as, a CPU (Central Processing Unit), as a representative one thereof, for example. For this reason, conventionally, suc...

AI Technical Summary

Benefits of technology

[0012] Then, according to the present invention, being accomplished by taking the drawbacks of the conventional arts mentioned above into the consideration thereof, in more details, it is an object to provide an electronic apparatus for dissolving such the problems coming up in the cooling system of the liquid type, applying the pump of the centrifugal type therein; in particular, a cooling system of the structure being applicable into a personal computer, of so-called the desktop-type or the notebook-type, and / or a server, etc., easily, and further, to an electronic apparatus having such the cooling system therein.

Problems solved by technology

Namely, if there is not filled with a sufficient amount of the liquid coolant as a body to be driven within the pump chamber thereof, when it starts up, the centrifugal pump makes so-called an idling, and depending upon the case, it results into a problem that an electric motor for rotationally driving the pump burns out, or a shaft thereof fastens, etc.

However, due to the requirement of small-sizing thereof, it is not necessarily in such a situation that the pump can satisfy such the requirement on the disposition or posture thereof mentioned above, fully.
