1. A pump comprising:
- a pump casing having a pump chamber, an inlet path through which a liquid is guided to the pump chamber and an outlet path through which the liquid is discharged from the pump chamber; and
an impeller, which is housed in the pump chamber, sucks the liquid through the inlet path into the pump chamber and pushes the liquid out of the pump chamber into the outlet path, wherein the outlet path has a first opening end which is opened in the pump chamber, and a second opening end located downstream of the first opening end, the first opening end having an opening area larger than that of the second opening end.

Abstract
A pump has a pump casing and an impeller. The pump casing has a pump chamber, an inlet path through which a liquid is guided to the pump chamber and an outlet path through which the liquid is discharged from the pump chamber. The impeller is housed in the pump chamber. With the rotation of the impeller, the liquid is sucked through the inlet path into the pump chamber and pushed out of the pump chamber into the outlet path. The outlet path has a first opening end which is opened in the pump chamber, and a second opening end located downstream of the first opening end. The first opening end has an opening area larger than that of the second opening end.

10. A cooling unit comprising:
-
a heat receiving portion which receives heat generated by a heat generating component;
a heat radiating portion which radiates the heat generated by the heat generating component; and
a circulation path which circulates a liquid coolant between the heat receiving portion and the heat radiating portion, wherein the heat receiving portion includes;
a casing having a coolant flow path in which the liquid coolant flows, an inlet path through which the liquid coolant is guided to the coolant flow path and an outlet path through which the liquid coolant is discharged from the coolant flow path; and
an impeller, which is provided in the coolant flow path, sucks the liquid coolant through the inlet path into the coolant flow path and pushes the liquid coolant out of the coolant flow path into the outlet path, and wherein the outlet path has a first opening end which is opened in the coolant flow path, and a second opening end located downstream of the first opening end, the first opening end having an opening area larger than that of the second opening end. - View Dependent Claims (11, 12, 13, 14, 15)

16. An electronic apparatus comprising:
-
a housing including a heat generating component; and
a cooling unit which cools the heat generating component by means of a liquid coolant, the cooling unit including a heat receiving portion which receives heat generated by the heat generating component, a heat radiating portion which radiates the heat generated by the heat generating component, and a circulation path which circulates the liquid coolant between the heat receiving portion and the heat radiating portion and transmits the heat generated by the heat generating component to the heat radiating portion via the liquid coolant, wherein the heat receiving portion includes;
a casing having a coolant flow path in which the liquid coolant flows, an inlet path through which the liquid coolant is guided to the coolant flow path and an outlet path through which the liquid coolant is discharged from the coolant flow path; and
an impeller, which is provided in the coolant flow path, sucks the liquid coolant through the inlet path into the coolant flow path and pushes the liquid coolant out of the coolant flow path into the outlet path, and wherein the outlet path has a first opening end which is opened in the coolant flow path, and a second opening end located downstream of the first opening end, the first opening end having an opening area larger than that of the second opening end. - View Dependent Claims (17)
