Flow rectifying cooling apparatus and a method for rectifying flow in a cooling apparatus

A method of cooling an electronic device, comprising:

• providing an internal space for accommodating an electronic circuit to be cooled;
• forming a first inlet opening for permitting a fluid to enter a cooling apparatus including a housing enclosing an impeller;
• forming a first exhaust opening for permitting the fluid to exit the cooling apparatus;
• permitting the fluid to enter the housing through a second inlet opening;
• permitting the impeller to rotate to increase a pressure of the fluid in the housing;
• permitting the fluid to exit the housing through a second exhaust opening;
• and
• impeding the fluid as it enters the housing through the second inlet opening with a projection extending from a terminal end of the housing, the projection having one of a semicircular cross section and an elliptical cross section such that the terminal end of the housing protrudes into the second inlet opening.

An apparatus comprising:

• an impeller;
• a housing having opposed upper and lower portions, the housing enclosing the impeller between the upper and lower portions;
• a first inlet opening formed between the upper portion of the housing and the impeller;
• a first projection formed on the housing that extends from the upper portion of the housing towards the impeller such that the first projection projects into the first inlet opening;
• a second inlet opening formed between the lower portion of the housing and the impeller;
• and
• a second projection formed on the housing that extends from the lower portion of the housing towards the impeller such that the second projection projects into the second inlet opening wherein at least one of the first and second projections has one of a semicircular cross section and an elliptical cross section such that a terminal end of the housing from which the at least one of the first and second projections extends protrudes into the inlet opening.

A computer comprising:

• an internal space for accommodating an electronic circuit to be cooled;
• a first inlet opening for permitting a fluid to enter a cooling apparatus;
• a first exhaust opening for permitting the fluid to exit the cooling apparatus;
• and
• an impeller unit to increase a pressure of the fluid;
• wherein the impeller unit comprises:
• a second inlet opening for permitting the fluid to enter the impeller unit;
• a second exhaust opening for permitting the fluid to exit the impeller unit;
• an impeller that rotates about an axis;
• a housing that encloses the impeller;
• and
• a projection extending from a terminal end of the housing, the projection having one of a semicircular cross section and an elliptical cross section such that the terminal end of the housing protrudes into the second inlet opening, the projection impeding the fluid as it enters the impeller unit through the second inlet opening such that a turbulence of the fluid is reduced as the fluid flows towards the second exhaust opening.

A computer comprising:

• an impeller;
• a housing having opposed top and bottom sides, the housing enclosing the impeller between the top and bottom sides;
• a first inlet opening formed between the top side of the housing and the impeller;
• a first projection formed on the housing that extends from the top side of the housing towards the impeller such that the first projection projects into the first inlet opening;
• a second inlet opening formed between the bottom side of the housing and the impeller;
• and
• a second projection formed on the housing that extends from the bottom side of the housing towards the impeller such that the second projection projects into the second inlet opening wherein at least one of the first and second projections has one of a semicircular cross section and an elliptical cross section such that a terminal end of the housing from which the at least one of the first and second projections extends protrudes into the inlet opening.
