Description

The combined structure of beam barrel and bearing

Technical field

The utility model relates to the combined structure of a kind of beam barrel and bearing, but espespecially a kind of rigid bearing have concurrently structure-reinforced and can improve the beam barrel in bearing and beam barrel working life and the combined structure of bearing.

Background technique

Press, due to the progress of Technology Times, the operational effectiveness of electronic component is more and more higher, so that the requirement to the heat dissipation of electronic component also increases to heat-sink unit thereupon.

Take host computer as example; the heat that its central interior processing unit (CPU) produces accounts for major part; in addition; central processing unit when heat gradually rising can cause and carry out usefulness and reduce; and when accumulation of heat during higher than its allowable limit; will force computer to work as machine, severe patient more may cause the damage phenomenon; And, for solving the problem of electromagenetic wave radiation, normally with the cabinet housing, seal this host computer, so that how the heat energy of central processing unit and other heating spare part (or claiming element) is derived fast, become an important topic.

when operating, can produce high temperature again or as large scale electronic equipments such as general work station or servomechanisms, when if its operational temperature surpasses certain operating temperature, its high temperature can affect work station, the task performance of the main frames such as servomechanism, even affect work station, electronic component in the main frames such as servomechanism burns and then causes fault, especially in work station or servomechanism, stored database or archives are even more important, what therefore it was of short duration works as machine or damages and can cause equally follow-up larger loss, therefore, work station, servomechanism is when setting up, this how heat dissipation problem temperature is maintained in operating temperature range be considerable design link.

Therefore dynamical heat-sink unit has been one of most important Research Emphasis of industrial circle today, with the electronic component to this generation high temperature, be provided with heat-sink unit and by this heat-sink unit, described electronic component dispelled the heat, described heat-sink unit is generally radiator or radiating fin correspondence and mixes a radiation fan and carry out heat radiation work.
