FIG. 3. Here, the block faces 102/202 include semi-annular trationtanks,evaporators,etc.(orcombinationsofthesecom ponents)areexceedinglycommon inindustryandinresearch labs.Researchersandengineersalsooftenneedtoexperiment Withmodels forcommon thermodynamic cycles,e.g.,refrig erationcycles(vaporcompressioncycle,Einsteincycle,etc.)20 andpoWercycles(Ottocycle,Dieselcycle,Braytoncycle, fasteneropenings110/210intheirblockfaces102/202,With Rankine cycle, etc.). While it is often desirable to generate prototypes or small-scale versions of such devices, they are usually time-consuming, di?icult, and expensive to con struct.Oneapproachcommonlyusedinlaboratoriesisto25 connectglassWarevessels(e.g.,?asks,toWers,heatexchang ers, etc.) With rubber tubing so that the vessels form some desired ?uid process model. Even apart from the signi?cant time and expense required for their construction, these are quitefragile,areunsuitableforpressurizedprocesses,andare 30 alsousuallyunsuitableforprocessesinvolvingextremetem peratures or corrosive materials oWing to the Weakness of the tubing. In some cases, more durable ?uid handling devices can be formed from metal vessels connected With (for example)braZedcoppertubing,buttheseinvolveevengreater35 time,cost,andfabricationburdens. A priorpatent(U.S.Pat.No.7,146,999toGieseetal., Whichisincorporatedbyreferenceherein)describesamodu lar ?uid handling system Wherein modular blocks bear pas sageWaysforcarrying?uids,andWhereininsertshavingdif 40 ferentfunctionality4e.g.,valveinserts,?lterinserts,turbine inserts,pump inserts,heating/coolinginserts,sensorinserts, ?oW routing/diverting inserts, etc.ican be inserted into selected blocks. The blocks, With or Without inserts, can be a?ixedtogethertoconstructadurable?uidhandlingdevice. 45 This document relates to improvements and additions to the modular ?uid handling system described in Us. Pat. No. 7,146,999 to Giese et al. the face fastener openings 110/210 being situated such that blocks 100/200 situated in face-to-face stacked relationship have their face fastener openings 110/210 coaxially aligned. ThisarrangementalloWstheblocks100/200tobea?ixed togetherinface-to-faceabutmentbyextendingafastener302 betWeen the aligned face fastener openings 110/210 of the abuttingblocks100/200. To provide a stable base for a ?uid handling device assembledfromaseriesofblocks100/200,amountingplate 304 is preferably provided upon Which the a?ixed blocks 100/200 may rest. The mounting plate 304 has a mounting surfaceWithplatefasteneropenings306arrayedtherein,such that When several blocks 100/200 are received thereon in side-to-sideabuttingrelationship,theplatefasteneropenings 306 coaxially align With the block face fastener openings 110/210. Fasteners 302 can then be extended through the block face fastener openings 110/210 and into the plate fas tener openings 306 to a?ix a block to the mounting plate 304. One or more of the blocks then takes the form of a ?uid passageblock100(seeparticularlyFIGS.2-3),Whereineach ?uid passage block 100 further includes one or more ?uid passages112WhichextendbetWeentheopposingblockfaces 102, and Which are situated betWeen the block bore 106 and theblocksides104.These?uidpassages112arepreferably regularlyarrayedabouttheblockbore106suchthatastacked arrayof?uidpassageblocks100havingtheirblockbores106 coaxially aligned Will also have their ?uid passages 112 coaxiallyaligned,suchthat?uidmay travelbetWeenthe?uid passages 112 of adjacently stacked ?uid passage blocks 100. One ormoreoftheblocksalsopreferablytakestheformof a ?uid intake/outlet block 200 Which includes the features of a ?uid passage block 100 (i.e., itincludes ?uid passages 212 similar to the ?uid passages 112 described above), but also includesducts214extendingfromthe?uidpassages212to the block bore 206, Whereby ?uid may travel betWeen the ?uid passages 212 and the block bore 206. These ducts 214 may assume a variety of forms, but are preferably formed as shoWn in FIGS. 2-3, Wherein the ducts 214 are de?ned as slottedopeningsWhichextendfromtheblockbore206tothe ?uid passages 212.
