摘要:
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.

There is disclosed a pump comprising a pump housing, an impeller, and a motor. The pump housing comprises a pump chamber and at least one communication port opening into this pump chamber. The impeller comprises a plurality of vanes and is rotatably disposed in the pump chamber. The motor has a plurality of phases, and rotates the impeller. The number of communication ports, the number of vanes, and the number of phases of the motor are set in such a manner as to indicate prime numbers.

An electronic apparatus includes a first housing and a second housing. The first housing incorporates a pump. The second housing incorporates a heat-radiating portion. The pump has a heat-receiving portion. A circulation path for circulating liquid coolant connects the pump and the heat-radiating portion. The circulation path has two pipes. The first pipe connects the pump to the coolant inlet port of the heat-radiating portion. The second pipe connects the pump to the coolant outlet port of the heat-radiating portion. The first and second pipes extend from two adjacent points on the pump, toward a midpoint between the coolant inlet port and coolant outlet port.

One surface of a base section having an open portion forming an inlet port of a fluid is thermally connected to a target module to be cooled. Pluralities of fins arranged in parallel are mounted on the other surface of a base section in a direction substantially perpendicular to the base section. A fan is arranged to permit the fluid to flow through the clearance between the adjacent fins. A wall section open to the inlet port of the fluid is mounted on the base section. A part of the wall section constitutes a detachable lid section. A partition plate having through-holes formed therein is arranged between the base section and the lid section so as to divide the space between the base section and the lid section into two fluid flowing channels consisting of a main flowing channel and an auxiliary flowing channel.

A carriage arm has a movement locus and supports a head that performs either one of recording information to a disk and reproducing information recorded on the disk. A carriage driving mechanism moves the carriage arm in a radial direction of the disk to perform a positioning of the carriage arm. A guide member changes a direction of air flowing on at least one of a peripheral portion of the disk and a neighboring portion of the peripheral portion toward a center portion of the disk. The guide member is provided in a position where the movement locus of the carriage arm is not blocked in an area of either one of the peripheral portion and the neighboring portion.

In a disc drive apparatus, a magnetic disc is housed in a casing and rotated by a motor mechanism. A magnetic head for recording information in a disc surface region and for reproducing the recorded information is supported by a carriage arm such that the magnetic head is swingable. Formed on that side of the carriage arm which faces the magnetic disc is a guide portion for guiding the air stream generated on the disc surface such that the air stream is allowed to flow in the longitudinal direction of the carriage arm.

An electronic equipment is provided with a fluid device using fluid including an additive, a main body comprising an installation site for installation of the fluid device and a detection part reserving the fluid. The detection part makes the fluid visible by means of the additive or is provided with a detection substance changing its nature when contacting the fluid, thereby leakage of the fluid is detected. The detection part may be further provided with electrodes to measure an electric property change therebetween. The detection part is disposed on either the installation site or the fluid device.
