Description
- The invention relates generally to an apparatus for cooling an electronic component and, more particularly, to a set of housings enabling the construction of a compact water-cooled cold plate with an integrated pump having high performance and reliability.
- With the recent onslaught of improvements in computer technology, the thermal load generated by personal computers has increased considerably. In order to ensure proper operation of the heat generating devices in the computer including, but not limited to, central processing units, video graphics processing units, and memory modules, liquid cooling systems have become widely used as a means to effectively dissipate the heat generated by these components. As the complexity of the liquid cooling systems increases, there also exists a need to simplify such systems.
- One type of cooling system employs a cold plate that is attached to a housing to form a cavity equipped with one or more inlet and outlet ports to circulate a coolant inside the cavity. The cold plate may be machined so that one of its faces forms a plurality of pins or fins. Such a device is also known as a water-block. A recirculation pump provides circulation of the coolant inside of the water-block. Water-blocks and pumps are separate units. Examples of pumps are found in U.S. Pat. Nos. 6,736,616, 6,713,918, and 6,897,596 B2.
- Embodiments of the present invention provide a cooling apparatus for cooling an electronic component to which the cooling apparatus is attached. The cooling apparatus has a simplified design that is achieved by combining several of its components into one, thus reducing the occupied space and improving flow rate and overall reliability of the cooling apparatus. More specifically, a set of housings enable the construction of a water-cooled cold plate including an integrated or built-in pump used for heat dissipation of electronic devices such as central processing units. The integrated cold plate and pump apparatus may be used in combination with a heat exchanger to form a liquid cooling system to dissipate the heat generated by computer components such as central processing units, video graphics processing units and memory modules.
- The present invention enables the construction of a device including a water-cooled cold plate and a recirculation pump described herein so as to combine them in order to form a single device which can be affixed onto a central processing unit for heat dissipation purposes. To this effect, a set of two housings is disclosed hereafter that represents one possible embodiment of the invention.
