Description

The water of big-block engine and the heat exchanger of air

The present invention relates to a kind of big-block engine especially water of marine engine and the heat exchanger of air, be preferably used in the pressurized air of cooling by the turbosupercharger compression, it has a comb radiator that is located in the air flow path, the comb radiator is transverse to the pipe of the comb radiator of air-flow direction extension, air can be flow through in its outside, water can be flow through in the inside, wherein, air by by opposite one another sidewall structure and be contained in the channel flow that the tube sheet that is equipped with comb radiator tube end between the sidewall structure constitutes, and, the water side of comb heat release organ pipe, by tube sheet each other back to set chamber, the outside be communicated with, the chamber constitutes by the lid that clamps tube sheet, in this case, be preferably in a side and establish the chamber that two that be separated from each other and imports water and outlet are connected at least, have two chambeies that interconnect at least at opposite side.

It is this type of device of a kind of interstage cooler of charge air cooling that US-A 3,881 455 discloses in form.In this known devices, the comb radiator constitutes a combiner, therefore only may mount and dismount difficultly.But along with the increase of size of engine, the requirement of cooling and thereby the physical dimension of interstage cooler and weight increase simultaneously all unavoidablely.This situation especially occurs on the marine engine.In marine engine, adopt 3 to 4 crust usually than higher boost pressure.In this case, general compressor efficiency is about 80%, thus the energy of nearly supply compressor 20% change heat into.Therefore pressurized air can reach 200 ℃.In order to need very big interstage cooler with this air cooling to about 50 ℃ of temperature.For marine engine, the bigger cooler of such class, weight can reach 5 tons.Therefore, need hoist in order to mount and dismount this cooler, though this hoist is provided in the cabin of ship, be difficult to reach the cooler that is located at turbosupercharger below usually with this hoist, this situation make care and maintenance work extremely difficulty carry out.Add, water side and the especially air side of this type of cooler is subjected to pollution to a certain degree, and thereby must be purified regularly because this pollution influences cooling effect and the pressure and the flow of air with to the disadvantageous mode of the work of motor.Especially particularly serious for the marine engine pollution problem, because the suction of air is carried out in the cabin usually there, because the blow-by of vent systems, so contain oil particles that cigarette ash and leakage of oil cause and other external grit or the like in the air in the cabin.Because the big humidity of ambient air, so do not lay the device that sucks air from the external world usually.In addition, the cabin also needs separate ventilation in this case.

In order to purify, cooler is repeatedly dismantled, and the physical dimension of big in this case weight and big volume is brought adverse influence.Purify and carry out by means of high-pressure injection usually.It is not dark that yet the degree of depth of cooler is invaded in high-pressure injection.Therefore, for the cooler of macrostructure size (as the cooler of marine engine etc.), in cooler, can produce by inaccessiable layer of high-pressure injection.Owing to this reason must be used the Chemicals that purifies usefulness, they understand accelerated corrosion certainly.If the purification of cooler is carried out at the scene, also be a kind of halfway purification probably with chemical formulation even utilize purification.

Therefore, setting out thus the objective of the invention is, and adopts the device simple and improvement of measure cheaply the above-mentioned type, with acquisition extremely good assembling and maintainability, and guarantees to have only small corrosion risk.

By the present invention is that to reach this purpose be to pass through the following measures that adopted: be provided with a plurality of oneself tube sheets that respectively contain one group of comb heat release organ pipe and settle these pipe ends, the comb radiator module that can operate separately, they can be by the tube sheet of co-planar arrangement, be placed in side by side of air flow path by sidewall structure in the zone of both sides, in order to pack into and to split out comb radiator module, this zone can be opened in a side at least, wherein, the tube sheet of the mutual coplane of each side, each can be with respect to the public lid sealing that faces this side by means of the seal arrangement of at least one annular in their fringe areas independently of one another.

Adopt these measures can overcome shortcoming described above and difficulty fully.Each comb radiator module has compact physical dimension, and weight is the part of whole comb radiator.Therefore, just can operate easily with hand or with smaller hoist.In addition, only need smaller place by comb radiator module of the present invention at disassembly status, this is for purifying and place demand during maintenance work plays a part favourable.Can expect on the one hand at this, in the cabin of steamer, exist narrow space usually.Another advantage by measure of the present invention is, can add the comb radiator module of detergent respectively from both sides, because their thickness is smaller, thus can be by means of high-pressure injection, for example steam jet cleans its whole thickness reliably.In this case can be all or cancellation purifies usefulness to the full extent Chemicals, this is for the reduction expense and prevent to have corroded favourable effect.Because each comb radiator modular design is unified,, therefore only cause work very in short-term to be interrupted so undoubtedly can change the comb radiator module that pollute with standby module simply.This purification of having polluted module just can be in the course of the work, that is carry out in motor operation and ship term of voyage, and this plays a part favourable for obtainable total Economy.Remaining whole cooler on the whole has compact structure and favorable cooling effect is arranged.

The favourable design of above-mentioned measure and the improvement that conforms with purpose illustrate in the dependent claims.As, comb radiator module with attach troops to a unit in its installing zone, have work in coordination along the flat supporting surface of extraction direction that embeds.Can make the assembling and the dismounting of each comb radiator module convenient especially like this.

Preferably be provided with the sidewall of a band transverse to the flat slide guide of air-flow direction extension at least, slide guide is used for supporting movably the horizontal piece of comb radiator along pushing direction that piece tube sheet in front, preferably supports whole comb radiator module.This sliding bearing can make packs into and splits out easy especially.Prevented also that meanwhile each comb radiator from can clash each other when packing into and split out.

Another favourable measure can be, comb radiator modular design is elongated cuboid, and it has a kind of and the corresponding broadside face of cross section installing zone, and a kind of elongate side that faces sidewall is arranged.This causes special compact structure mode, and this mode of structure makes might be operated simply and purify easily and reliably.

A favourable design of above-mentioned measure can be that comb radiator module can be clamped between the public lid under not interconnected situation, lid can be connected with screw with sidewall.Formed so simply and the structure of supporting certainly.In order to change a comb radiator module, only need pull down one of two lids, preferably that lid that is not connected with water out with water inlet.By the installing zone opening of formation like this, the in fact floating type module that is installed with can be inserted and pull out.Need not to dismantle other screw link in this case, thereby make maintenance work easy to implement.

According to another design of being taken measures, comb radiator module can individually be connected with cover screw.Sidewall can be compacted in this case.This structure is insensitive especially for the thermal expansion or the contraction of comb radiator.In this case, being located at seal arrangement in the tube sheet location, to need not compensate for dilatation in an advantageous manner poor.Therefore the screw that sets for lid is connected here and need only bears hydraulic pressure in an advantageous manner.In order to split out a comb radiator module, their screw that obviously need only unclamp two lid locations connects.

In such scheme, lid does not abut on the relevant tube sheet with preferably having flange.Needed screw link can be along the surface distributed of lid.On this avris that can power be evenly distributed in lid by favourable mode and the inner supporting surface.

Another favourable measure is, for each piece tube sheet sets a plurality of (best two) O-ring seal by echelon configuration one by one.This not only forms a kind of sealing especially reliably, but also can check sealing effect by favourable mode.For this reason, lid can be provided with the peep hole of attaching troops to a unit in tube sheet simply, and draw from the zone between two seal arrangements in these holes.Can determine the blow-by of first seal arrangement immediately thus, thereby prevent that reliably the water that can damage motor from entering the pressurized air problem.

For the operation that makes comb radiator module is more prone to, comb radiator module can be established the eye bolt that is contained on its tube sheet, and may also be provided with the supporting element that is positioned at central authorities in the elongate side district.

Other favourable designs of above-mentioned measure and the improvement that conforms with purpose illustrate in remaining dependent claims, and can find out from the following explanation of doing by means of accompanying drawing to embodiment.

Fig. 7 is located at the sealing device structure that two annular seals are respectively arranged in the tube sheet district and gives an example; And

Fig. 8 with by the different another kind of alternative plan of structure shown in Figure 7.

Be used to drive the big-block engine of boats and ships etc. such as the structure and the working method of high output diesel engine is well-known.Such motor does not generally all have exhaust-gas turbocharger, comes compressing charge air with it.By the efficient of this class exhaust-gas turbocharger as can be known, approximately will infeed 20% of energy and change heat into.Consequently can cause heating pressurized air to about 200 ℃, owing to so reduced filling to the firing chamber, so this is undesirable.For making the firing chamber obtain good filling, pressurized air to flow through one be located at the waste gas supercharger back as shown in Fig. 1 and 6 among between cooler 1, it is cooled to about 50 ℃ with pressurized air.

Can find out also that by Fig. 1 and 6 interstage cooler 1 is inlaid in the exhaust-gas turbocharger of not representing and leads in the air passageways 2 that engine charge of expression is taken among the figure from figure.The flow direction of air is represented with direction arrow L.The downstream of interstage cooler 1 can be a water separator that does not have expression here,, isolates from air because the condensed water that cooling forms before air infeeds engine chamber by it.Attach troops to a unit in the installing zone of interstage cooler 1 in order to constitute one, air passageways 2 is interrupted.Be located at the end that the forward and backward channel section of installing zone faces one another, can be shaped on the end frame 3 of annular, the interstage cooler 1 in this relevant installing zone of packing into is with respect to they sealings.

By Fig. 3 and 4 as seen, interstage cooler 1 contains a comb radiator of arranging along air flow path, and it has the pipe 5 that extends and be provided with the comb radiator of outer radiating fin 4 transverse to air-flow direction, and air flows through in pipe 5 outsides.The inside of the pipe 5 of comb radiator adds cooling water.The end of the pipe 5 of comb radiator is installed in the tube sheet 6.

The water side of comb heat release organ pipe 5 be located at before the flow direction and after the distribution chamber and the chamber 8,9 of confluxing is communicated with, they are the boundary with tube sheet 6 internally, externally the

lid

10,11 with clamping tube sheet 6 is the boundary.Lid 10 plays so-called end cap, and its chamber 8,9 is separated from each other by next door 12 in Fig. 3 and 4, and is provided with and is used to feed water or the connecting

tube

13,14 of draining.Work to turn to lid with lid 10 relative lids 11, its chamber 8,9 interconnects by the one or more apertures 15 in the existing partition in Fig. 3 and 4.The flow direction of water is represented with direction arrow W.The water footpath is flowed into or is discharged by end cap 10.Change flow direction in 11 turning to cover.

Under any circumstance the comb radiator is made up of a plurality of comb radiator modules 16, oneself the tube sheet 6 that they respectively have one group of comb heat release organ pipe 5 and its end is installed.As Fig. 1 and 2 obviously represents, comb radiator module 16 has a kind of moulding of elongated cuboid, it have two with in air passageways 2, attach troops to a unit in the corresponding broadside face of installing zone cross section of interstage cooler, and two elongate side of extending transverse to their are arranged.

As Fig. 2 and 6 clearly represented, it is folded that the horizontal piece 16 of the comb radiator of each interstage cooler 1 constitutes a buttress, wherein, couples together the tube sheet 6 mutual coplanes of each module.In represented embodiment, it is mutually the same to be combined into the folded comb radiator module 16 of buttress.But also can consider to have the module of different-thickness, that is to say that the elongate side of module has different width, so that can be combined into the cooler of various width.

The common mutually tube sheet 6 that connects of folded two ends of above-mentioned module is separately with respect to

relevant lid

10 or 11 sealings.For this reason, on two tube sheets 6 of each comb radiator module 16, be provided with along its annular on every side seal arrangement 19.In order to constitute seal arrangement 19, so-called O RunddichtringO can be set simply, they are inserted in the groove that matches that mills out on the relevant tube sheet 6.Lid be shaped on 10,11 attach troops to a unit in all facing to the abutment face of seal arrangement 19 of tube sheet 6.These abutment face constitute by the ring cover limit of widening and by the next door 12 with or without aperture 15 that its support side of passing lid has been widened equally.

In that a horizontal piece is folded when having only two comb radiator modules 16,

cover

10,11 and be provided with a next door 12, so covering, each respectively forms two chambeies 8,9.If a module is folded four comb radiator modules 16 are arranged, so as shown in Figure 2,

lid

10,11 respectively has three next doors 12, thereby make each lid form four chambeies 8,9, median septum in end cap 10 is provided with the aperture in this case, and the central partition in turn-around wall 11 does not have the aperture, so comb radiator module adjacent one another are flows along different directions.This principle can be used too in bigger module is folded.

The stream of air is in side relative to each other, by each other always co-planar arrangement and with respect to

lid

10 or 11 sealings and thereby tube sheet 6 sealed to each other as the border.Be provided with sidewall in other both sides, they constitute the passage of a border seal as the air that flows through the comb radiator with tube sheet 6.Sidewall all seals with respect to the end towards them above the segmentation of air passageways 2.As shown in Figure 2, in order to constitute sidewall, tube plate structure opposite each other is provided with the sidewall 7 of cross-over connection.This type of sidewall 7 can be fixed in the side of extending between two tube plate structures on the end frame 3 of air passageways section by it, as among Fig. 2 by the hole that is used for screw etc. represented.

Sidewall 7 in Fig. 2 does not divide again.But also can consider for example to be further divided into like this, that is, set the corresponding strip sidewall of width of width and tube sheet 6 for each comb radiator module 16.If these strip sidewalls couple together mutually adjacent to each other, form one as top wall at sealing as described in Fig. 2, then can be connected equally on the end of air passageways section.

In structure shown in Figure 1, each comb radiator module 16 has the elongated sides board member 7a that couples together with tube sheet 6 usefulness screws between tube sheet 6, and they are narrower than tube sheet 6.In this case, need additional continuous side walls 7b, they can be connected airtightly air passageways 2 segmentations facing to the end on.As shown in Figure 1, they can have an avris ring frame, and/or as shown in Figure 6, are connected to each other by the frame parallel with tube sheet 6.What under any circumstance all be formed with a flange shape annular is used to cover 10,11 junction surface.In order to prevent to form air bypass between lateral plate member 7a and sidewall 7b, shown in Fig. 6 top, lateral plate member 7a can be provided with lip seal 17, and their overlap joints also thereby have been blocked gap between lateral plate member 7a and adjacent upper portion side wall 7b.Lip seal 17 can be designed to the spring thin plate.Be in the underside area of relative position at comb radiator module 16 and lip seal 17, their lateral plate member 7a is located on the adjacent lower wall 7b, or with guide plate 23 cooperatings that are contained on the lower wall 7b, thereby formed a kind of seal arrangement of maze type.

In the design shown in Fig. 2 and 3,

lid

10,11 is connected with sidewall 7 usefulness screws.This is equally applicable to the structure by the relevant sidewall 7b with 6 of Fig. 1, has also additionally represented there to be connected with the screw of the end frame 3 of air passageways end.Being connected among Fig. 2 of this lid also done expression by the screw hole that covers that is suitable for there.In

lid

10,11 and design that sidewall 7 or sidewall 7b are connected with screw, the folded floating ground of module that is made of comb radiator module 16 is contained in two and also can be pressed between them between covering 10,11.

Cover

10,11 for this reason and be provided with the flange 20 that matches with sidewall 7 or sidewall 7b, they can be connected with sidewall 7 or sidewall 7b by screw 21.Because the pipe 5 of comb radiator cools off, and sidewall 7 or sidewall 7b are uncooled, so produce different thermal expansions.The length difference that causes thus must compensate by seal arrangement 19.The elasticity of employed O RunddichtringO thereby suitable size design must be arranged.As shown in Figure 3, between the abutment face that flange 20 and sidewall 7 or sidewall 7b match, the airtight seal arrangement 22 of can packing into.When this same seal arrangement also is applicable in cooler being contained in the recessed area that is formed by end frame 3 in the air passageways 2.

In Fig. 3, after changeing 90 ° with sidewall 7, view represents in order to simplify.In fact they are parallel to the figure paper plane.

As seen from Figure 1, the comb radiator module 16 that does not have connection mutually that module is folded can insert one by one in the relevant installing zone independently of each other, that is insertion is in the channel region on border, side with sidewall 7b.For this reason, in Fig. 1,10,11 be the installing zone on boundary by sidewall 7b and lid, be opened in a side.Therefore usually in the

lid

10,11 is not preferably covered 11 with turning to of being connected with draining of feedwater and is removed.By the inlet of formation like this, comb radiator module 16 can be inserted and extracted out.For these work can be carried out especially like a cork, comb radiator module 16 and affiliated installing zone have the edge that matches each other and insert and extract out the flat supporting surface of direction.For this reason, at least one (being the bottom here) guide plate 23 that sidewall 7b has mentioned above being provided with, guide plate is designed to slide rail, and comb radiator module 16 moves on it by the supporting surface 24 on its tube sheet 6.In the design of pressing Fig. 1, two tube sheets 6 of each comb radiator module 16 are provided with the supporting surface 24 that matches with corresponding slide rail 23.But.If when being provided with corresponding supporting surface direction of insertion in front (that is being drawn in right-hand) that tube sheet 6 in Fig. 1 on, in any case also enough.The tube sheet 6 of back can insert in the step, for example as seen from Figure 3.

In the design of pressing Fig. 1, the lateral plate member 7a between tube sheet 6 that comb radiator module 16 has been mentioned on elongated sides is provided with, the supporting surface that they can have the supporting surface 24 with tube sheet 6 to be attached thereto accordingly.Therefore on module, form along whole block length extend and with slide rail 23 cooperative supporting surfaces, thereby cause less pressure.Meanwhile form a kind of labyrinth sealing, it can prevent to produce air bypass in comb radiator outside.

For ease of operating each comb radiator module 16, can on it, be provided with the traction piece that is applicable to hoist etc.For this reason as illustrated in fig. 1 and 2, can establish 25, one of eye bolts that are contained on the tube sheet 6 pushes away or draws equipment to be attached thereto.In addition, comb radiator module 16 preferably also is equipped with central suspension ring 26.For this reason, in pressing the embodiment of Fig. 1, side plate 7a is provided with a rib 28 at least, is shaped on suspension ring 26 in the rib 28.Represented for example in, side plate 7a strengthens by vertical rib and cross rib, wherein, suspension ring 26 just are located at the cross rib central authorities that are positioned at central authorities, just are positioned at the top of relevant comb radiator module 16 centers of gravity.For obtaining very high rigidity, two side plate 7a of each comb radiator module 16 can be connected to each other by supporting 27.In Fig. 2, along the folded continuous sidewall 7 of whole module, can be connected to each other by supporting 27 equally, support on 27 and be provided with the flange 29 that is positioned at its end for this reason.This supports 27 and equally can be when needed be connected with starter motor etc.In pressing the structure of Fig. 2, support 27 and be connected with the screw of sidewall 7, when dismantling comb radiator module 16, must unclamp.

Represented interstage cooler in Figure 4 and 5, as top illustrated, the lid 10 that equally folded by module with a plurality of comb radiator modules 16, comb radiator module 16 is public and 11 and between the tube sheet 6 of the comb radiator module 16 that is set up in parallel, extend and form as the sidewall 7 on border, air flow path side.The comb radiator module 16 same tube sheets 6 of coplane each other that pass through are placed in the relevant installing zone side by side.In pressing the embodiment of Figure 4 and 5, comb radiator module 16 is different with the embodiment who presses Fig. 2 and 3, and it couples together with

lid

10,11 usefulness screws 30.Sidewall 7 is connected with

lid

10,11 screws of no use in this case, but such by what can obviously find out among Fig. 5, the tube sheet that is set up in parallel 6 that is contained in coplane has between the flange shape fringe area of suitable protrusion amount.Here, sidewall 7 extends along the folded whole thickness of module equally.Also can consider to be subdivided into again and interconnectedly have an elongate side wall member with the width corresponding width of tube sheet 6, or a kind of and similar structure of Fig. 1.Advantage according to the cooler construction of Figure 4 and 5 is, different thermal expansion between comb radiator module 16 and the sidewall 7 can not cause moving and size error of tube sheet 6 and lid 10,11.Set preferably being designed to the O RunddichtringO equally and abutting in the seal arrangement 19 that covers on 10 or 11 in the zone of each tube sheet 6 need not be born differential expansion in this case.The screw connection set that constitutes by screw 30 thereby need only bear hydraulic pressure.

Screw 30 is arranged in the zone of vertical median plane of relevant comb radiator module 16, and thereby is fixed on each relevant tube sheet 6 along a central symmetry line.Therefore, form distributions of uniform power in all places of annular seal 19.Therefore covering 10,11 does not here need rim lip, but has only one for constituting the edge of widening of sealing abutment face.Next door 12 is widened as the side that reclines among the embodiment above the table, is connected across on two vertical abutment joints between the adjacent tube sheet 6 so that form one, is used for the abutment face that double width is arranged of the seal arrangement of two tube sheets.Therefore, be positioned at the screw 30 in above-mentioned vertical median plane zone, run through and cover 10,11 chamber 8,9.

Lid

10,11 is provided with the lining 31 of attaching troops to a unit in screw 30.

In represented example, screw 30 is screwed in the tube sheet 6 respective threads holes by the threaded stem built in its end.But also can consider to be provided with the through bolt that runs through two lids 10,11.In order to dismantle a comb radiator module 16, should get next lid, preferably turn to and cover 11.In addition, the screw of the comb radiator module 16 that change on another lid that is end cap 10 connects and must unclamp.If be provided with the sidewall 7 of whole formula, they are connected with tube sheet 6 usefulness screws, and the screw connection of that comb radiator module 16 that will dismantle so also must be unclamped.When having sidewall with tube sheet 6 respective width, use needn't so do.For the ease of inserting and extracting out, as in the above embodiments, can be provided with suitable supporting surface equally in this case.When integral sidewalls, also can carry out like this, that is, only get next sidewall 7 in order to dismantle a comb radiator module 16.In this case, another sidewall and two

lids

10,11 can keep original position.Need only remove the comb radiator module 16 that will dismantle is connected at the screw of two lid sides and side wall side.The screw of Chai Xie comb radiator module does not connect, and can unclamp slightly simply in order to obtain enough fit up gaps.

By among the cooler embodiment of the present invention, each comb radiator module 16 always can be dismantled individually at all, and other comb radiator module 16 is automatically stayed original position, need not additional support.

Under simple situation, each tube sheet 6 has an annular seal enough.In Fig. 3 and 4 represented situations, tube sheet 6 abuts in and covers 10,11 parallel with it pressing on the face.For improving reliability, also can establish two or more seal arrangement 19a, b by echelon configuration one by one.This class is embodiment be illustrated in Fig. 7 and 8.Use seal arrangement 19a, the b by the echelon configuration of two connections, can carry out leak check easily.For this reason,
