Pump and pumping system

Abstract

To provide a pump and pumping system in which the mounting efficiency is improved and which can be controlled without pulling out a flexible tape, etc. from a pump in order to satisfy a demand for smaller information systems and a demand for mounting various kinds of electronic components with high density. A pump comprising an impeller having a plurality of vanes around its outer circumference and a rotor magnet on its inner circumference, a plurality of salient poles positioned opposite to the rotor magnet to radially extend outwardly in the radial direction of the impeller, a pump casing interposed between the rotor magnet and the plurality of salient poles, a driving IC for supplying current to coils wound around the salient poles, and an electronic board on which the driving IC is mounted; wherein the electronic board is fixed to the pump casing while the driving IC is interposed between the plurality of salient poles.

Description

technical field

[0001] The invention relates to a pump and a pump system, which are used for the circulation of refrigerant for cooling electronic components and the fuel circulation of a fuel cell, and in particular to a pump and a pump system for improving the installation efficiency. Background technique

[0002] In recent years, with the high performance and high functionality of information equipment, the heat generated by the electronic components inside the information equipment has gradually increased, so cooling devices have become more and more important. For example, since the clock frequency of the CPU has greatly improved compared to the past, a method in which a refrigerant is circulated inside to cool the LSI and the like is actually adopted. On the other hand, in recent years, the development of fuel cells is rapidly advancing. This fuel cell is a battery that circulates fuel and extracts electrical energy, and it tends to be more and more miniaturized, and ...
