Description
Technical field
The present invention relates to the chilly plate of novel microflute group more particularly to a kind of chilly plates of wedge-shaped microflute group.
Background technique
To adapt to microelectronic component and system micromation and the development of high-power and dissipating for superelevation thermal power densities
Heat demand proposes the concept of the chilly plate of microflute group in educational circles, and the chilly plate of microflute group is by a series of single rectangular micro-channel battle arrays
Column composition, the heat of system surfaces is taken away by the cooling working medium constantly flowed in conduit.Existing result of study shows narrower
The heat transfer property of traditional rectangular micro-channel can be enhanced in conduit, i.e., smaller hydraulic diameter and bigger conduit depth-width ratio, but same
When also result in bigger waterpower crushing and bigger power consumption.For the limitation for breaking through conventional monolayers rectangular duct structure, seek more
Excellent micro-channel structure, enhancing microflute group chilly plate heat-sinking capability while, reduces its waterpower crushing and power consumption is micro- for microflute group
The development of cold plate technology or even the development of microelectronics system heat dissipation technology are all of practical significance.
Summary of the invention
In order to solve the above technical problems, the object of the present invention is to provide a kind of chilly plate of wedge-shaped microflute group, the wedge shape microflute
The chilly plate of group.
The purpose of the present invention is realized by technical solution below:
A kind of chilly plate of wedge shape microflute group, the chilly plate is by a series of identical wedge-shaped micro-channel array group of planforms
At in wedge-shaped micro-channel entrance, into channel outlet section, channel width is linearly restrained toward central axes direction, and conduit height is past
Vertically upward linear diverging, and channel width convergence ratio and conduit high divergence ratio are mutually inverse.
Compared with prior art, one or more embodiments of the invention can have following advantage:
Radiating efficiency is high, and fluid-solid conjugated heat transfer ability is strong, is able to satisfy excessive heat power density electronic component and system
Radiating requirements, and waterpower crushing is small, it is required low in energy consumption, it may advantageously facilitate the chilly plate heat dissipation technology development of microflute group.
Detailed description of the invention
Fig. 1 is the chilly plate overall structure diagram of wedge-shaped microflute group；

Cold plate overall length and beam overall, Ht、HcWith HbRespectively chilly plate upper cover plate, conduit and substrate level, WwWith WcRespectively chilly rib of slab
The width of plate and conduit.
In wedge-shaped micro-channel entrance, into channel outlet section, channel width is linearly restrained toward central axes direction, and conduit is high
It spends toward vertically upward linear diverging, and channel width convergence ratio and conduit high divergence ratio are mutually inverse, enable chilly plate
Overall length is L, and channel outlet width and height are respectively WcoWith Hco, apart from channel entrance y=yiThe channel width and height point at place
It Wei not WciWith Hci, wherein 0≤yi≤ L, then have: micro-channel width convergence ratio is α=Wco/Wc, micro-channel high divergence ratio β=
Hco/Hc, the β of α=1/；For any y=yi, micro-channel width is Wci=Wc(1–(1–α)yi/ L), micro-channel height is Hci=Hc/
(1–(β–1)yi/βL)。
The chilly plate of above-mentioned wedge shape micro-channel array composition is prismatic.
Although disclosed herein embodiment it is as above, the content is only to facilitate understanding the present invention and adopting
Embodiment is not intended to limit the invention.Any those skilled in the art to which this invention pertains are not departing from this
Under the premise of the disclosed spirit and scope of invention, any modification and change can be made in the implementing form and in details,
But scope of patent protection of the invention, still should be subject to the scope of the claims as defined in the appended claims.
