Description
Technical field
The present invention relates to a kind of water cooled heat radiating row and its manufacture method, the heat abstractor with radiating row.
Background technology
Radiator is used to accelerate radiating rate, and the heat transfer of heater can be made into air and can play extension heating
Object service life etc. acts on.It can all be related to radiating for example current electronics industry is quickly grown, on numerous electronic equipments
Problem to electronic equipment, it is necessary to be radiated it is necessary to use radiator.
In general radiator all adds the structure of radiator fan using fin, and it passes through internal structure external structure reasonable in design
Preferable radiating effect can be played.But the electronic system that some heating powers are higher or thermal power density is more concentrated, often
Because space limits, the very large fan-cooled radiator of receiving volume is unable to above thermal source or is unable to reach the heat dissipation of requirement,
One kind radiating countermeasure is liquid cooling heat radiation system, and liquid cooling system can be transferred heat to heat separately by the worker quality liquid of flowing
One more spacious position, and arranged by a larger radiating and effectively distributed heat.Typical water-cooling system
Bulk cargo is put with lower component：Absorb heat head or heat collector (being commonly called as water-cooling head), radiating row, cycle fluid liquid (generally mainly into
Part be water, herein with the liquid refrigerant of any composition of liquid water reference), water pump, circulating line and water tank.Water-cooling head mainly by
Copper or aluminium are made, and it contacts the heat of simultaneously absorption heater part with heater members by the heat collection of thermal source and conducted to working solution
Body water；Water pump promotes liquid water to flow to radiating row along circulating line；Radiating row is the gold that ventilating water pipe is left in an inside
Belong to radiator, its function is to add convection type to be transferred in air by heat transfer the heat that water carries, it will usually is arranged in water
Larger area of dissipation is set and uses fan forced convection to strengthen and cross-ventilated heat exchange effect；Circulating line is divided into
Quality of rubber materials or metal pipe material, form water circulation channel；Water tank mainly lays in hydraulic fluid water, in water because the reason such as evapotranspire becomes
The standby effect of redundancy can be played when few, can also be attached to water cooling drip chamber or other parts, be not necessarily intended to be independently arranged.
Existing radiating row is mostly using wave sheets and flat pipeline (or circular pipe) welding production technology, (such as vapour
The water-cooling system of car radiator and host computer) its pipeline with both ends hydroecium is similarly to carry out welding to merge.Enter stove weldering
First the more than one piece such as wave sheets, pipeline, hydroecium to be assembled using nipper and fixed before connecing, its process is cumbersome and wastes time and energy；Dress
Manual operations is relied on mostly with precision, and homogeneity of product is not easy to ensure；More fatal is flat pipeline and both ends hydroecium
Binding site is complex-shaped and dead angle is a lot, solder skip rosin joint often occurs in welding, its product qualified rate is relatively low, it is necessary to personnel
Leak detection is reprocessed, and has been raised production cost and has been reduced production capacity；And rosin joint part can not effectively be detected in production line, after installation pass through by
The leakage of rosin joint position is also always puzzlement water under the conditions of multiple thermal shock and therewith caused expand with heat and contract with cold effect and vibrations
The quality chronic disease of cold industry for many years.Leakage water shortage will make hydraulic fluid missing and then stop circulation, can not effectively take away water-cooling head
Heat, gently then cause damage of components, heavy then system crash loss of data.
The content of the invention
The purpose of the present invention is to overcome the above-mentioned weak point of existing radiating drainage technique, realizes and to provide a kind of structure tight
