Abstract
The invention relates to an annular micro-passage heat exchange plate which comprises micro-passage heat exchange bodies (1) which are arranged in an annular shape and a guide sheet (2). Fluid flows in from one end, is diverted through the guide sheet (2), and then enters an annular micro-passage array. Heat is transmitted in the annular micro-passage array so that heat exchange is realized. Finally, the fluid flows out of the other end. The annular micro-passage heat exchange plate can increase a heat exchange area and prolong staying heat exchange time of the fluid in the passage, and therefore heat exchange effect is improved. The annular micro-passage heat exchange plate is small in size and compact in structure, can be used for heat dissipation of a single heat source, and is used for heat exchange between cold fluid and hot fluid. Moreover, a plurality of heat exchange plates can be combined into a whole after being overlapped.
Description
Technical field
The present invention relates to a kind of heat exchanger plates with annular micro channel array, can be widely used in field of radiating.
Background technology
At present, along with the development of science and technology, the integrated level of electronic product is more and more higher, causes heat dissipation problem increasing, and the highest heat flow density surpasses 1 * 10
6W/m
2Temperature raises and will directly cause electronic product performance decline, reliability reduction, security to descend.Traditional air-cooled technology has been difficult to meet the demands, and good heat dissipation technology energy savings not only, the service life that also can improve electronic product.
Micro-channel heat exchanger is the heat exchanger components with many microchannels, space compactness, because having the characteristics such as low thermal resistance, high heat conductance, bigger serface, is just obtaining increasingly extensive application.At present the microchannel of micro-channel heat exchanger mostly is greatly linearity, as Chinese patent " a kind of micro-channel heat exchanger " (application number: 201010567766.X) with " compact microchannel heat exchanger " (Granted publication number: CN201434622Y).And the non-linear shape microchannel not only can increase heat exchange area and extend the stop heat-exchange time of fluid in passage, and fluid when flowing in passage because of continuous change flow direction, turbulence and the eddy current of fluid have been promoted, fluid and channel surface constantly bump, the thermal resistance boundary layer will constantly be separated and be destroyed, and heat transfer property is compared also with the linearity microchannel and therefore obviously strengthened.(Granted publication number: zigzag microchannel heat sink CN202111976U), to compare heat transfer efficiency higher with the microchannel of linearity as the Chinese patent microchannel heat sink of electronic devices and components " be used for ".But up to now, not yet find to have the report of the heat exchanger plates of annular micro channel array.
Summary of the invention
In order to overcome the existing deficiency that the heat exchanger plates volume is large, heat transfer area is little and heat transfer property is poor, the invention provides that a kind of volume is little, compact conformation, heat transfer area is large and heat transfer property is good annular Thermal Performance of Micro Channels plate.
Purpose of the present invention is achieved through the following technical solutions:
A kind of annular Thermal Performance of Micro Channels plate comprises the Thermal Performance of Micro Channels plate and the flow deflector that distribute ringwise.Fluid flows into from an end, through the flow deflector shunting, then enters annular micro channel array, and heat transmits in annular micro channel array, thereby realizes heat exchange, flows out from the other end at last.
The cross sectional shape of above-mentioned annular microchannel comprises V-arrangement, trapezoidal, rectangle, semicircular arc.The described annular microchannel degree of depth is 0.1-2mm, and width is 0.1-1mm, and spacing is 0.1-1mm.The heat exchanger plates material that adopts comprises copper, aluminium, steel, glass or other Heat Conduction Materials.The processing method that adopts comprises LIGA, turning, chemical etching, laser ablation, spark machined.Described invention can be used for the heat radiation of single thermal source, links into an integrated entity after also can the multi-disc heat exchanger plates is superimposed, is used for the heat exchange between cold and hot fluid.The superimposed mode of described multi-disc heat exchanger plates comprises series, parallel.Described multi-disc heat exchanger plates connected mode comprises that welding, bolt connect.Between cold and hot fluid, heat exchange mode comprises following current, adverse current.The flow deflector material comprises copper, aluminium, steel, glass or other Heat Conduction Materials.
The present invention has following advantage:
(1) good effect of heat exchange.Compare with the linearity microchannel, not only increased heat exchange area, also extended the stop heat-exchange time of fluid in passage, thereby strengthened heat transfer effect.
(2) pressure drop is little.Fluid mostly is greatly laminar flow in the microchannel, thereby flows steadily, and pressure drop is less.
(3) volume is little.Under the condition of equal exchange capability of heat, to compare with the double pipe heat exchanger that is using, volume can reduce decades of times.
(4) applied widely.Namely can be used for the heat radiation of single thermal source, link into an integrated entity after also can the multi-disc heat exchanger plates is superimposed, be used for the heat exchange between cold and hot fluid.
