Description
Technical field
The present invention relates to the heat transfer technology field, specifically a kind of Double layer high efficient water-cooling base plate for the electronic devices and components cooling.
Background technology
Along with the high power of electronic devices and components, high integrated develop rapidly, the components and parts that specific volume power density is higher are used more and more widely.In real work, 10 ℃ of the every increases of the temperature of power component, its life-span will reduce half, and therefore, the radiating element that matches with high performance components is also changed at generation technique gradually.The air-cooled type of cooling of tradition can't satisfy the job requirement of high-power electronic component, and water-cooled just progressively replaces the air-cooled cooling that is mainly used in high performance components.Compare with ventilation panel, water-cooling base plate has the characteristics of the maintainability that the unit volume radiating efficiency is large, reliability is high and good, is a kind of heat dissipation equipment that is widely used in daily and industrial high-power electronic component.
The heat that produces during power model work is delivered to its crucial thermal component by with water-cooling base plate contact-making surface being installed, and simultaneously, cooling fluid flows out from delivery port behind the cooling liquid flowing channel of flowing through after entering water-cooling base plate by water inlet.Cooling fluid is taken away the heat that power model produces in the flow process of coolant flow channel, thereby reduces the temperature of power model, makes its normal operation.
At present, the water-cooling base plate product generally is comprised of parts such as each one of flat board, frid (or frid and radiating fin) and entery and delivery ports on the market.Frid is cavity with flat board formed cavity (or being used for placing radiating fin) after welding, is called into the water cavity with the direct-connected cavity of water inlet, is called the water outlet cavity with the direct-connected cavity of delivery port.
The water-cooling base plate that now generally uses is the two-sided cooling of individual layer cavity.The water-cooling base plate of the two-sided cooling of individual layer cavity is to avoid the heat radiation between the power model of two-sided installation to disturb, can increase inner chamber and radiating fin height, so that the degree of depth of the machining of frid increases, production efficiency reduces, produce a large amount of waste of raw materials, thereby cause cost up, simultaneously because the increase of inner chamber and radiating fin height, the maximum that also can reduce its inner chamber is born pressure, reduces the water-cooling base plate reliability.
Common water-cooling base plate is to set out the water chamber demarcation strip below the plate face of power model installation site.The plate face below of this power model installation site sets out the water chamber partition plate structure, can weaken cooling fluid to the cooling effect of the power model of water chamber body position installation, causes its working temperature to raise, and reduces its reliability and useful life.
Summary of the invention
According to the technical problem of above-mentioned proposition, and provide a kind of Double layer high efficient water-cooling base plate.
The object of the invention is to overcome weak point of the prior art, can improve the utilance of water-cooling base plate unit volume heat dissipation capacity, raising power model working space; Reduce water-cooling base plate mechanical processing difficulty, reduce machining amount, enhance productivity, reduce cost; Optimize the water-cooling base plate internal structure, improve the radiating efficiency of product.
The technological means that the present invention adopts is as follows:
A kind of Double layer high efficient water-cooling base plate, the dull and stereotyped II, water inlet and the delivery port that comprise frid, be fixed on the dull and stereotyped I of described frid upper surface and be fixed on described frid lower surface, it is characterized in that: described frid comprises the right baffle-plate of formation " worker " font frid, right baffle plate and be fixed on described right baffle-plate and described right baffle plate between, the transverse slat that described frid is separated into double-layer cavity; Also be provided with dividing plate between described right baffle-plate and the described right baffle plate, described dividing plate is divided into intake antrum transverse slat and water chamber transverse slat with transverse slat; The double-layer cavity that described transverse slat is separated into is become four can for the cavity of coolant flow, be respectively into water cavity I, water inlet cavity II, water outlet cavity I and water outlet cavity II by described baffle for separating; Be equipped with radiating fin in described water inlet cavity I and the described water inlet cavity II.
