Description
Technical field
The present invention relates to a kind of H Exch that is used for air conditioner for vehicles, more particularly, relate to a kind of H Exch, the desiccant container that desiccant wherein is housed is inserted among the house steward, and described H Exch is suitable for as the condenser that receptor is housed.
Background technology
In H Exch, in a kind of condenser such as the condenser of can whole packing at receptor, the desiccant container that desiccant is housed is inserted at least one among a pair of house steward.For instance, shown in Figure 13 and 14, some heat-transfer pipes 101 are inserted among the house steward 102, and radiating gill 112 is arranged in the both sides of each heat-transfer pipe 101.The desiccant container 105 that desiccant 104 is housed is inserted among the house steward 102, and wherein desiccant 104 is contained in the sack 103 with fluid permeability.Desiccant container 105 is bearing on supporting member 106 and 107.The bottom of desiccant container 105 is inserted in the filter screen part 108.Lid 110 and 111 is located at house steward 102 two ends, and filter screen part 108 is bearing on the lid 111.
In this H Exch, the refrigerant that flows into house steward 102 flows into desiccant container 105 from the heat-transfer pipe 101 that is arranged in supporting member 107 tops by the opening 113 that is located on the desiccant container 105, after the moisture of removing with desiccant 104 in the refrigerant, refrigerant temporarily is stored in the fluid storage part 114 of house steward's 102 formations below the supporting member 107, flows into the heat-transfer pipe 101 of the formation over cooling core that is communicated with fluid storage part 114 then.
Yet, in above-mentioned H Exch, constitute by resin or metal (as fine aluminium or the aluminum alloy) tubular shell that outside face is provided with some openings 113 because the desiccant container 105 of desiccant 104 is housed, so have following problem.For example, desiccant container 105 be by molded form as injection-molded situation under, must be provided with the withdrawing pattern part of mould, such as the tapering part 115 shown in Figure 15.So the internal diameter of the inside face of desiccant container 105 longitudinally reduces gradually towards the centre portion direction.Therefore, the operability that the sack 103 that desiccant 104 is housed is inserted desiccant container 105 can become very poor.In addition, in order to form the tubulose desiccant container 105 that has opening 113 on the outside face by injection-molded, must use complicated insertion mode structure and slide construction, this not only makes mould become very expensive but also molding process also may often break down.
Improve the operability that sack 103 inserts desiccant containers 105 for avoiding forming above-mentioned gradual change withdrawing pattern partial sum, can consider a kind of method of making resin or metal straight pipe and processing opening 113 in the above.Yet, in this method,, the total cost of making H Exch is improved greatly because increasing of procedure of processing can make the cost of making desiccant container 105 significantly increase.
And in above-mentioned H Exch, in order to improve the operability of desiccant container 105 being inserted house stewards 102, supporting member 106 and 107 patchhole 116 and 117 diameter are set to be slightly larger than the external diameter of desiccant container 105.That is, between the inside face of the outside face of desiccant container 105 and patchhole 116 and 117, can there be the gap inevitably.For this structure, when H Exch is installed on the vehicle as A/C, can be because the vibration of desiccant container 105 produce noise, perhaps because desiccant container 105 and supporting member 106 and 107 contact and rub and the foreign matter of generation can be brought in the circulating fluid.
Therefore, requirement provides a kind of H Exch that improves structure that has, and can improve the operability of desiccant being inserted desiccant container, thereby reduces the cost of making desiccant container, and can improve the operability of the whole assembling of H Exch, thereby realize the decline of H Exch cost.
In addition, also requiring provides a kind of improved H Exch, can show high heat-exchange capacity, and can improve the operability of the whole assembling of H Exch.
And, also require to provide a kind of H Exch of structural development, even be used as under the situation of air conditioner for vehicles, can prevent that noise from producing or foreign matter enters circulating fluid at H Exch.
Summary of the invention
The invention provides a kind of heat converter structure.This H Exch comprises: a pair of house steward; Some heat-transfer pipes can be communicated with house steward and the extension that is parallel to each other with this; With the desiccant container that desiccant is housed, can be inserted among at least one among a pair of house steward.Described desiccant container is made of the tubular shell that has opening, and its split shed vertically extends on the whole length of this tubular shell continuously along tubular shell.
The tubular shell that constitutes desiccant container can have C shape transversal surface.Above-mentioned this desiccant container is easy to make, such as, can be by the one flat plate rolling forming be formed the opening that extends longitudinally, perhaps can be by in straight tube, forming the otch that longitudinally extends continuously with circle, avette, track type or polygon transversal surface.
The opening of desiccant container preferably has the angle in circular segment of 10 degree to the 90 degree scopes on the transversal surface of desiccant container.If less than 10 degree, the size of opening will become too little and make and enter desiccant container in-to-in flow resistance and enlarge markedly.On the other hand, if greater than 90 degree, the size of opening will make desiccant container reduce the maintenance intensity of desiccant too greatly.
The opening direction of desiccant container can be decided on the purposes of H Exch, more particularly, can determine according to the fluid flow state that flows among the house steward.Such as, can adopt such structure, it is passable that wherein aperture arrangement becomes to make the fluid that is discharged to the house steward from heat-transfer pipe, after flowing through between the outside face of desiccant container and house steward's inside face, flows in the desiccant container by opening.This structure is very desirable for some situation, because if aperture arrangement is in the inserting side of heat-transfer pipe, will flow directly in the desiccant container by opening from the refrigerant of heat-transfer pipe, and the flow of refrigerant in the desiccant container is interfered; Perhaps because the fluid refrigeration agent of discharging from the opening that is arranged in the fluid storage part flows directly into the heat-transfer pipe that constitutes the over cooling core, might produce bubble and make the gas/liquid separation become not enough, therefore, vapor phase refrigerant might enter the over cooling core, thereby cooling effectiveness is reduced.In this case, opening preferably is arranged in heat-transfer pipe and inserts in the opposite side of house steward's a side in the 270 degree angle in circular segment scopes.
Also can adopt a kind of like this structure, wherein aperture arrangement is inserted house steward's a side at heat-transfer pipe.This structure is very desirable for some situation, because if aperture arrangement is in a side opposite with the heat-transfer pipe inserting side, will be earlier and the collision of the outside face of desiccant container from the refrigerant of heat-transfer pipe, flow into the space between the outside face of desiccant container and house steward's the inside face then, relatively large loss of pressure may appear in this flow process, even in fluid storage part too relatively large loss of pressure may appear, because the fluid refrigeration agent of discharging by opening is just to flow into behind the space between outside face that flows into desiccant container and house steward's inside face in the heat-transfer pipe of formation over cooling core.In this case, opening preferably is arranged in the 180 degree angle in circular segment scopes of heat-transfer pipe insertion house steward one side.
In addition, in the present invention, can adopt following structure to prevent producing noise or to prevent that foreign matter from entering in the heat-exchange fluid.That is, can adopt a kind of like this structure, wherein be provided with ring-shaped bearing piece in the house steward, inserting in the hole of this ring-shaped bearing piece is inserted with desiccant container, and desiccant container is fixed on the inner peripheral surface of supporting member patchhole.
In this structure, desiccant container can be fixed on the supporting member by soldering.According to H Exch of the present invention generally is to form interim confined state by each parts, then all parts is once put into stove and is carried out soldering and make.So the soldering between desiccant container and the supporting member also can be carried out in stove with other parts.In addition, after desiccant container is inserted house steward, can desiccant container be fixed on the supporting member by the diameter that enlarges desiccant container.
Periphery at ring-shaped bearing piece can be provided with otch.This otch can form fan-shaped.By the loss of pressure that such otch can reduce fluid among the house steward is set.
In addition, house steward is last can be provided with the slit that along the circumferential direction extends, and is used for supporting member is inserted among the house steward.By such slit is set, can easily supporting member be inserted among the house steward with high position precision.
The tubular shell that constitutes desiccant container can be by resin, or metal such as fine aluminium or aluminum alloy are made.
Can be widely used in the H Exch that is inserted with desiccant container among various types of house stewards according to H Exch of the present invention, wherein in the desiccant container desiccant is housed.Especially, structure according to H Exch of the present invention is suitable for such mistake cold mould condenser, wherein house steward's bottom is provided with the fluid storage part, and condenser zone has and is used for the condensation of refrigerant core of condensating refrigerant and over cooling by the over cooling core of the condensed refrigerant of condensation of refrigerant core.
In H Exch according to the present invention, desiccant container is made of the tubular shell that has opening, and its split shed vertically extends on the whole length of this tubular shell continuously along tubular shell.Such tubular shell can create in a procedure of processing at an easy rate, such as, by the dull and stereotyped rolling forming of monolithic is formed the slit between its two ends, perhaps by in commercially available straight tube, forming the otch that longitudinally extends continuously, perhaps by injection-molded or compression moulding.In addition, owing to when desiccant is inserted tubular shell, can opening be enlarged towards both sides, so can improve the insertion operability of desiccant.And, after desiccant inserts, can desiccant be firmly held in the tubular shell.
In addition, owing to be provided with above-mentioned opening, when desiccant container was inserted house steward, the diameter of the diameter of desiccant container during compared with its free state can reduce, so can insert desiccant container at an easy rate and pass supporting member.After desiccant container is inserted house steward, the diameter of desiccant container can change back to the preceding original free state that inserts owing to its elastic restoring force, if the diameter of desiccant container when free state is set to equal or slightly greater than the diameter of supporting member patchhole, the outside face of desiccant container can contact with the inner peripheral surface of supporting member patchhole naturally so, thereby can easily and securely desiccant container be fixed on the position suitable among the house steward.And, when desiccant container is connected with supporting member by soldering in this state, desiccant container is gone up in position with respect to supporting member is fixing with high precision.
Therefore, in H Exch according to the present invention, can in a procedure of processing, make desiccant container at an easy rate with low cost, and can make desiccant insert desiccant container and desiccant container to insert supporting member and all become and be more prone to, so, the operability of the whole H Exch of assembling can be improved, and the cost of making H Exch can be reduced.
In addition, when the aperture arrangement of desiccant container during at an opposite side with the heat-transfer pipe inserting side regional, because can be by rectification from the refrigerant that heat-transfer pipe is discharged, refrigerant can be flowed in the desiccant container, so can prevent interference with stable flow regime to fluid in the desiccant container and liquid level by opening.Therefore, the gas/liquid in the desiccant container is separated and can fully be carried out, and prevents that vapor phase refrigerant from entering the over cooling core, thereby improves cooling power.
Perhaps, when the aperture arrangement of desiccant container during at heat-transfer pipe inserting side regional, owing to can significantly reduce the loss of pressure that opening caused that passes desiccant container because of fluid, thereby reduce the loss of total pressure in the H Exch greatly, so can improve heat exchange performance.
And, when adopting this structure that desiccant container is fixed on the supporting member inner peripheral surface, owing to can go up with securely desiccant container being fixed in position easily, so, can prevent that also desiccant container from vibrating even there is vibratory force to be applied on the H Exch.Therefore, can suitably prevent noise and production of foreign matters.

The specific embodiment
Referring to Fig. 1 to 4, there is shown H Exch according to first embodiment of the invention.This embodiment shows the situation of the condenser that applies the present invention to be equipped with receptor, specifically, is applied to the situation of cold mould condenser.
In Fig. 1, cross cold mould condenser 1 and comprise second house steward 2 and first house steward 3 who vertically extends and be parallel to each other, and with this to house steward 2 with 3 fluids are communicated with and some heat-transfer pipes 4 of the extension that is parallel to each other.Corrugated fin 5 is located between each adjacent heat-transfer pipe 4, and the outside of outermost heat-transfer pipe 4 also has the outermost radiating gill.Refrigerant inlet pipe 6 is located at second house steward's 2 top, and refrigerant outlet pipe 7 is located at second house steward's 2 bottom.
The inside that is provided with dividing plate 8, the second house stewards 2 among second house steward 2 is divided into upper space and lower space by dividing plate 8.By this dividing plate 8, the heat exchange zone that is furnished with many heat-transfer pipes 4 in the H Exch is divided into, being used for condensation enters the condensation of refrigerant core 9 of refrigerant in the condenser 1 and is used for over cooling by the over cooling core 10 of condensation of refrigerant core 9 condensed refrigerants.That is,, make the whole core of condenser 1 be divided into condensation of refrigerant core 9 and over cooling core 10 by integrally formed dividing plate 8 is set in second house steward 2.In the present embodiment, the refrigerant path of the condensation of refrigerant core 9 that is made of some parallel heat-transfer pipes 4 in condensation of refrigerant core 9 zones is unidirectional paths.Therefore, the refrigerant that enters second house steward 2 from inlet pipe 6 passes each heat-transfer pipe 4 the condensation of refrigerant core 9 along one-way passage, flows into first house steward 3 then.After refrigerant flowed into first house steward 3 and drops to the entrance of over cooling core 10, refrigerant entered in each heat-transfer pipe 4 of over cooling core 10, passes heat-transfer pipe, flowed out from outlet pipe 7 then.Yet condensation of refrigerant core 9 also can have the form of two or more refrigerant passage directions.
In addition, in the present embodiment, with respect to crossing whole core area in the cold mould condenser 1, the area Occupation efficiency of over cooling core 10 is set at about 10%.According to an experiment of the present invention, this Occupation efficiency is preferably within about scope of 5% to 12%.By Occupation efficiency being arranged in this scope, can suppress to realize best over cooling when high side pressure increases, wherein the high side pressure increase is to cause owing to condenser being installed in the space constraint that causes in the vehicle motor chamber.Specifically, suppressing this pressure increase is to realize by can carry out supercooled structure in limited condenser space.And, when avoiding, can realize the over cooling of optimum degree because of the increase of high side pressure increase causing fuel consumption in vehicles.
In addition, in the present embodiment, among first house steward 3, constitute fluid refrigeration developing agent storage part 11 (fluid storage parts) with the cooresponding part of over cooling core 10 entrance parts at least.Will be after the moisture the refrigerant that condensation of refrigerant core 9 is sent is removed, refrigerant temporarily be stored in the fluid refrigeration developing agent storage part 11, enters therefrom then in each heat-transfer pipe 4 of over cooling core 10.
Also show the desiccant unit 13 that is inserted among first house steward 3 among Fig. 2 to 4.Desiccant unit 13 comprises the sack 17 that desiccant 12 is housed and has fluid permeability and is used for holding the desiccant container 18 of these sacks.
In the present embodiment, desiccant container 18 is made of the tubular shell that has opening 19, and its split shed 19 longitudinally extends on the whole length of housing continuously.The desiccant container 18 that has opening 19 has C shape transversal surface.In addition, in the present embodiment, the opening 19 of desiccant container 18 is arranged in the circumferential position of desiccant container 18 transversal surfaces, should make to be discharged to after refrigerant the house steward 3 must flow through between the outside face of desiccant container 18 and house steward's 3 inside face, could pass through in the opening 19 inflow desiccant containers 18 from the heat-transfer pipe 4 that constitutes condensation of refrigerant core 9.In other words, opening 19 is arranged in and makes the refrigerant of discharging from heat-transfer pipe 4 can not flow directly into desiccant container 18 in-to-in positions.Because the refrigerant of discharging from heat-transfer pipe 4 does not flow directly into desiccant container 18, just can prevent the interference to fluid and liquid level in the desiccant container 18, and can guarantee the stable separation of gas/liquid.As shown in Figure 3, in the transversal surface of desiccant container 18, the angle in circular segment of opening 19 size Cr is arranged on 10 degree to the scopes of 90 degree.
In the present embodiment, because desiccant container 18 is made of the tubular shell that has the opening 19 that longitudinally extends continuously, so when desiccant 12 sack 17 of desiccant 12 (or be equipped with) is inserted desiccant container 18, by make desiccant container 18 elastic deformations towards both sides enlarged openings 19, can at an easy rate desiccant 12 be inserted and be contained in the desiccant container 18, thereby improve the operability of insertion work.And after inserting, the shape of desiccant container 18 is owing to its recovery of elasticity characteristic becomes original size again, so desiccant 12 can be firmly held in the desiccant container 18 that inserts house steward 3.
In addition, owing to be arranged on 10 degree to the scope of 90 degree at the angle in circular segment open C r of desiccant container 18 transversal surface split sheds 19, so can prevent to enter the excessive increase of the flow of refrigerant resistance of desiccant container 18, and can guarantee that desiccant 12 is had enough maintenance intensity simultaneously.
Fig. 5 shows the transversal surface according to total tube portion in the H Exch of second embodiment of the invention.In the present embodiment, 19 of the openings of desiccant container 18 are to making after the refrigerant that is discharged to from the heat-transfer pipe 4 that constitutes condensation of refrigerant core 9 house steward 3 must flow through between the outside face of desiccant container 18 and house steward's 3 inside face, could pass through opening 19 flows in the desiccant container 18, specifically, opening 19 is arranged in a side opposite with heat-transfer pipe 4 inserting sides.But, opening 19 also can be arranged on the other circumferential position, as among Fig. 6 to shown in the improvement of the foregoing description.That is, opening 19 can be arranged in heat-transfer pipe 4 and insert in the opposite side of a side of house stewards 3 in the 270 degree angle in circular segment scopes.Embodiment shown in Fig. 6 is identical with the embodiment shown in Fig. 3 basically.In addition, equally in these embodiments, the angle in circular segment Cr of desiccant container 18 transversal surface split sheds 19 be preferably disposed on 10 the degree to 90 the degree scopes within.
In these embodiments, the refrigerant of sending from heat-transfer pipe 4 collides on the outside face of desiccant container 18, and between the outside face of desiccant container 18 and house steward's 3 inside face, flow, enter desiccant container 18 by opening 19 then, shown in the arrow in Fig. 5 and 6.Refrigerant flows in the desiccant container 18 with stable flow regime in by rectification, therefore, can prevent interference, can improve the gas/liquid separating effect in the desiccant container 18, and can prevent that vapor phase refrigerant from entering in the over cooling core 10 fluid and liquid level in the desiccant container 18.In addition, in fluid storage part 11, because the fluid refrigeration agent of discharging by opening 19 does not directly enter in the heat-transfer pipe 4 that constitutes over cooling core 10, so can prevent further that vapor phase refrigerant from entering over cooling core 10.Therefore, can improve the cooling power of condenser 1 greatly.
Fig. 7 shows the transversal surface according to total tube portion in the H Exch of third embodiment of the invention.In this embodiment, the opening 19 of desiccant container 18 is directly in the face of the heat-transfer pipe inserting side.But, opening 19 is not limited in this position, but can be arranged in the scope of heat-transfer pipe inserting side 180 degree angle in circular segments, as shown in Figure 7.In the time of in opening 19 is arranged in this zone, because after refrigerant entered house steward 3 from heat-transfer pipe 4, the refrigerant amount that collides with desiccant container 18 outside faces became seldom, so can reduce loss of pressure.
Therefore, in this embodiment, because aperture arrangement becomes to face the heat-transfer pipe inserting side, so the refrigerant of discharging from heat-transfer pipe 4 flows directly into the desiccant container 18 by opening 19 basically.That is, shown in arrow among Fig. 7 since can with the collision of the outside face of desiccant container 18, and can between the outside face of desiccant container 18 and house steward's 3 inside face, not form by-pass flow, refrigerant can enter in the desiccant container 18 under the state of shortest path.Therefore, can reduce loss of pressure greatly.In addition, in fluid storage part 11, the fluid refrigeration agent similarly flowing directly in the heat-transfer pipe 4 that constitutes over cooling core 10 under the shortest path state, therefore also can reduce this a part of loss of pressure too greatly.
Fig. 8 to 12 shows the 4th embodiment of the present invention.Desiccant container 18 is inserted in the patchhole 22 and 23 of ring-shaped bearing piece 15 and 16, and the outside face of desiccant container 18 is welded on the patchhole 22 and 23 inside face of supporting member 15 and 16 with soldering.Patchhole 22 and 23 diameter are set to equal or the external diameter when being in free state less than desiccant container 18 slightly.Supporting member 15 and 16 usefulness solderings are welded on house steward 3 the inside face.On supporting member 15 and 16, be provided with fan-shaped otch 24 and 25.In this embodiment, otch 24 and 25 openings of sizes are set to haply big or small the same with the opening 19 of desiccant container 18.House steward 3 is provided with and is used for supporting member 15 and 16 slits 26 and 27 that insert among the house steward 3.
In this embodiment, owing to desiccant container 18 has the opening 19 that longitudinally extends continuously, so when desiccant container 18 was inserted house stewards 3, the diameter of desiccant container 18 can be owing to its elastic deformation and less than the diameter when it is in free state.Therefore, even the diameter of patchhole 22 and 23 equals or the diameter of the desiccant container 18 during slightly less than free state, also can at an easy rate desiccant container 18 be inserted in the patchholes 22 and 23.After desiccant container 18 is inserted by patchhole 22 and 23, because the green diameter the when diameter of desiccant container returns to free state, so the outside face of desiccant container 18 and patchhole 22 contact with 23 inside face, thereby can desiccant container 18 be securely fixed on the appropriate location among the house steward 3 by supporting member 15 and 16.And, when all parts being placed on when carrying out soldering in the stove, can make desiccant container 18 be soldered to the appropriate location of supporting member 15 and 16 with high precision in this state.In this state,, also can reduce or prevent that the desiccant container 18 among the house steward 3 from vibrating, and can prevent owing to vibration produces noise or foreign matter even be used at condenser 1 under the situation of air conditioner for vehicles.
Though desiccant container 18 is to be welded on supporting member 15 and 16 with soldering in the present embodiment, but after desiccant container 18 is inserted the patchhole 22 and 23 of supporting member 15 and 16, also can enlarge the diameter of desiccant container 18 with similar instruments such as anchor clamps, desiccant container 18 is connected on supporting member 15 and 16.
