Description
Technical field
The invention belongs to Electronic cooling technical field, is related to a kind of reinforced heat exchanger and method from concussion.
Background technology
With the development of electronic technology, it is desirable to continuous improvement cause power consumption to be continuously increased so that electronic equipment dissipating heat face
The pressure faced also is continuously increased.The heat-sinking capability that the requirement of cooling system improves system reduces weight diminution volume again.Although
Substantial amounts of research has been done, has improved the complexity and total system power consumption of the system that both increases each time.Therefore, heat dissipation technology has been
As the major obstacle of electronic technology development.At present, although air-cooled technology has some progress, with crescent day day
Electronic technology is compared, the air cooling needs that still energy-electronics technology does not radiate.Although new other types such as liquid cooling skill
Art has higher radiating efficiency, but adds size, weight, complexity and the cost of cooling system.In many
Under such circumstances, the method being more prone to is to provide air blast cooling to be cooled down to component.Existing for existing air-cooled technology
Main problem is that the thermal resistance between spreader surface and air is larger, causes the temperature between spreader surface and cooling air
Difference is larger, so as to cause the less efficient of radiator, its reason is that spreader surface air, should there are one " quiescent layer "
" quiescent layer " has completely cut off the heat exchange between spreader surface and moving air.Existing radiator can not destroy " static
The spoiler of layer ", reduces the thickness of " quiescent layer " generally by the flow velocity of increase wind, but can thus increase radiator
Volume, weight, input power and noise etc..
The content of the invention
The purpose of the present invention：In the case of no increase size, weight, input power and noise, increase radiator
Heat exchange efficiency, can meet high-power electronic device heat dissipation the needs of.In order to significantly strengthen the heat exchange efficiency of air cooling heat exchanger, this
Text proposes a kind of reinforced heat exchanger and method from concussion, can meet the needs of high-power euthermic chip heat dissipation.
Technical scheme：A kind of reinforced heat exchanger from concussion, it is characterised in that include radiator, disturb
Flow；Spoiler is fixedly mounted on the centre position of radiator heat-dissipation passage, is not struck against during guarantee spoiler earthquake scattered
Hot fin；When air flow so that spoiler is when producing vibration in its intrinsic frequency, the concussion amplitude maximum that spoiler produces,
The heat exchange efficiency highest of radiator.
The spacing of the radiated rib of the radiator is between 0.3~1.5mm.
The ratio between spacing of the spoiler thickness and radiated rib is between 0.05~0.6.
One radiator can install multiple spoilers, and a spoiler can only be installed in each heat dissipation channel.
Heat-exchange method of a kind of integrated form from the reinforced heat exchanger shaken, it is characterised in that pass through the air of flowing
Spoiler produces concussion, and the spoiler of concussion destroys in spreader surface " static " air layer, adds the flow-disturbing journey of air
Degree, so as to improve the heat exchange efficiency of heat exchanger.
The present invention has the advantage that effect：A kind of reinforced heat exchanger of concussion and method certainly are a kind of novel enhanceds of research and development
The device of heat exchange efficiency, " quiescent layer " of spreader surface is trapped in by the concussion of spoiler, so as to reduce sky come " elimination "
The thermal resistance of gas and spreader surface strengthens the heat exchange property of radiator.The configuration of the present invention is simple, it is easy to manufacture, without volume
Outer power, using air flow so that spoiler is produced from concussion, by destroying fluid boundary layer, greatly improves heat convection effect
Rate, so as to strengthen air radiator heat dissipation performance, and does not increase radiator volume, weight substantially.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention
Fig. 2 is principle of the invention figure
Embodiment
As shown in Figure 1.
A kind of integrated form is by radiator, spoiler and treats radiating element and its attached from the reinforced heat exchanger shaken
Part forms.Under normal circumstances, device to be radiated is welded on pcb board, and radiator is together with treating that radiating element fits closely.
In order to reduce radiator and treat the thermal resistance between radiating element, in radiator and radiating element filling flexible should be treated under normal circumstances
Heat conductive pad.Spoiler by be bonded, weld or heat dissipation channel that mechanical connection manner is fixed between.
Spoiler is installed on the centre position of radiator heat-dissipation passage, the spacing of the radiated rib of radiator 0.3~
Between 1.5mm, spoiler thickness is between 0.01~0.2mm.
The ratio between spacing of spoiler thickness and radiated rib is between 0.05~0.6, it is ensured that spoiler earthquake process
In do not strike against radiated rib.
When air flow so that installed in heat dissipation channel centre position spoiler in its intrinsic frequency produce vibration when,
The concussion amplitude maximum that spoiler produces, the heat exchange efficiency highest of radiator；
Multiple spoilers can be installed on radiator, a spoiler can only be installed in each heat dissipation channel.
Operational process：The air of flowing encourages the spoiler between heat dissipation channel in flow process so that disturbs
Flow produces vibration, and spoiler vibration air produces the air bolus perpendicular to flow direction.The air bolus breaks ring radiating surface surface
Between " static " air layer so that " static " air layer depart from spreader surface and be mixed into the air of flowing, so as to reach
Strengthen the effect of the heat exchange efficiency of radiator.
