Description
Affiliated technical field
The present invention relates to a kind of regenerator, be specially the hot machine heat-exchanger type regenerator of a kind of Stirling.
Background technique
The hot machine of modern Stirling all adopts wire gaze heat accumulating type regenerator, does not break through the traditional design theory of the hot machine of single active chamber Stirling.The hot machine regenerator of Stirling traditional design theory is exactly to pay attention to the space conduction loss of heat, ignores the thermal loss of waiting for that heat-exchange time causes.Paper " output work and the efficient of the hot machine of Redlich-K wong gas Stirling " has been studied the relation of heat exchange stand-by period and thermal loss, draws to shorten to wait for that the heat exchange stand-by period can reduce the conclusion of thermal loss.And the shortest heat exchange stand-by period of the hot machine of Stirling is the active chamber that the appearance endothermic process such as is in and the active chamber countercurrent flow that puts thermal process such as be in! Its theoretical heat exchange stand-by period is near zero.A kind of countercurrent flow formula of Chinese invention patent regenerator (201110006278.6) just is based on this principle.Yet this invention is still keeping and is reducing traditional thinking that heat vertically flows as far as possible, attempts to reach and reduce longitudinal heat flux and lose through horizontal heat exchanger channels is set.Its result must cause flow resistance big, manufacture and design difficulty.
The power of the hot machine of modern Stirling is little, and below 100KW, wire gaze heat accumulating type regenerator can satisfy its performance requirement basically.Reach hundreds of KW even surpass on the hot machine of high-power Stirling of 1,000 KW the just too late heat-exchanger type regenerator of wire gaze heat accumulating type regenerator combination property at the hot acc power of Stirling.
And research and develop the hot machine of powerful Stirling is the only way of solar energy thermal-power-generating, hybrid vehicle! Chinese invention patent Stirling reversible heat engine (200710050949.2) has been properly settled the agent structure problem of the hot machine of high-power Stirling." research of novel Stirling engine design theory " and " Stirling engine ultimate pressure and the analysis of mean temperature relation " these two pieces of papers provide a cover complete Stirling reversible heat engine design and calculation method and formula.
The characteristics of the hot machine heat-exchanger type regenerator of Stirling heat exchange pattern are that two-way heat exchange, high frequency switch, the pressure sudden turn of events.How to be directed against above characteristics, realize countercurrent flow with simple and reliable structure? The research of this respect at present also is in the starting stage, reports rare.
Summary of the invention
In the objective of the invention is to solve at one time, an active chamber is in endothermic process, and another active chamber is in the hot machine countercurrent flow of the Stirling problem of exothermic process.Because heat exchange is carried out between two active chambers, the hot machine of Stirling must have the even number active chamber.
To achieve these goals, scheme of the present invention is: its structure comprises a horizontal central layer, vertical central layer, multilayer parallel heat-exchanging plates, four heat-insulating blocks, four shell pieces, an outsourcing heat insulation layer.Laterally central layer intersects vertically with vertical central layer; Parallel multilayer heat exchanging plate intersects vertically with horizontal central layer, vertical central layer respectively; Laterally central layer is with vertically central layer is with parallel multilayer heat exchanging plate quadripartition, and the outer surface of outermost surface heat exchanging plate is connected with the horizontal central layer of the Bian Douyu of all heat exchanging plate, vertical central layer.Two faces perpendicular to horizontal central layer are bi-side, and each side is divided into two-part by horizontal central layer; Two faces perpendicular to vertical central layer are both ends of the surface, and each end face is divided into two-part by vertical central layer.Marginal gap between all heat exchanging plate of shutoff bi-side; Marginal gap between the heat exchanging plate of the vertical central layer heteropleural of interlayer shutoff both ends of the surface; Form that two multilayers are alternate, two-port is at the vertical working medium flow channel of central layer heteropleural, two heat exchanger channels are space crossed, the diagonal angle is communicated with.Marginal gap between the heat exchanging plate of the vertical central layer homonymy of interlayer shutoff both ends of the surface forms then that two multilayers are alternate, port is at the vertical working medium flow channel of central layer homonymy, two heat exchanger channels space parallels, and homonymy is communicated with.Four heat-insulating blocks are close to four shell piece internal surfaces respectively, and four shell pieces wrap up partly parallel heat-exchanging plates of four between the vertical central layer of horizontal central layer, and are connected with the vertical central layer of horizontal central layer, form the shell of sealing.Respectively there are two connecting tubes at the shell two ends, case surface outsourcing heat insulation layer.
Said horizontal central layer is the framework that the middle part connects, and interior empty profile and multilayer parallel heat-exchanging plates joint cross section profile coincide.
Said vertical central layer is the framework that the middle part connects, and interior empty profile and multilayer parallel heat-exchanging plates joint section profile coincide.
Said heat exchanging plate is the thin plate of arbitrary surface.
Said each layer of heat exchanger channels two ends port all is communicated with the two ends connecting tube, and active chamber heater and radiator are communicated with two heat exchanger channels respectively with separately.
Said working medium flow channel port is at vertical central layer homonymy, and laterally central layer needn't be provided with.Because laterally the effect of central layer is the vertical central layer homonymy two working medium flow channels of packing.
The invention has the advantages that: one be the working medium of two active chambers in the reverse flow of heat exchanging plate two sides, flow to high frequency and switch, heat is corresponding bi-directional on the heat exchanging plate two sides, heat exchanging plate does not need very big heat storage capacity, good effect of heat exchange.The 2nd, heat exchanging plate substituted metal silk screen, manufacturing process is simple, has reduced cost, and reliability is higher.The 3rd, be particularly useful for high-power Stirling engine.
