Pump, cooling apparatus, electrical appliance and personal computer combined with the pump

Abstract

A pump according to the present invention includes a casing including a pump chamber through which a fluid flows, an impeller rotatably mounted inside the pump chamber, a suction port mounted on the casing for suctioning the fluid into the pump chamber by the rotation of the impeller; and a discharge port mounted on the casing for discharging the fluid out of the pump chamber by the rotation of the impeller, and the suction port and the discharge port are oriented so as to extend in different directions.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a pump for cooling a heat-generating component in an electrical appliance or a personal computer, and more particularly to a pump with an improved structure of a suction port and a discharge port. [0003] 2. Description of the Related Art [0004] A fluid pump as disclosed, for example, in Japanese Published Unexamined Patent Application No. 2001-123978 and Japanese Published Unexamined Patent Application No. 2001-132677 is currently available. Such a fluid pump is provided with a casing including therein apump chamber, a suction port and a discharge port located in the casing, and a disc-shaped impeller rotatably mounted inside the pump chamber and having pump grooves along a periphery thereof for carrying a liquid inside the pump chamber. In this fluid pump, when the impeller is rotated the pump grooves act to suction the liquid through the suction port into the pump chamber, and also...

Benefits of technology

[0011] Therefore, an object of the present invention is to provide a pump that can efficiently cool an object to be cooled.

[0013] Upon combining with the pump a heat-receiving section placed in contact with the object to be cooled for removing the heat from the object to be cooled by the fluid flowing therein, and a heat-dissipating section including a fluid pipe having the end portions connected to the suction port and the discharge port and in which the fluid that has removed the heat from the object to be cooled flows, a cooling apparatus can be achieved.

[0014] With such a configuration, since the suction port and the discharge port are extended in different directions, the end portions of the fluid pipe no longer have to be bent in an acute angle for connection with the suction port and the discharge port. Consequently, a pressure loss at the connection point can be minimized.

Problems solved by technology

However, the cooling apparatus thus constructed has the following drawback.

Such a structure increases the pressure loss inside the pipe 14 and hence reduces a flow amount and speed of the fluid, thereby resulting in lowering the cooling performance.
