Definitions
- the present invention relates to an air guide box and in particular an air guide box for a heating, air conditioning and / or ventilation installation of a motor vehicle.
- At least one air treatment device which can be, for example, the evaporator of an air conditioning installation, a heating body being able to be supplied with liquid. engine cooling, electric heater or the like.
- part of the air is usually guided through the air treatment device while another part can be guided in front of the air treatment device.
- the invention provides an air guide box, in particular for a heating, air conditioning and / or ventilation installation of a motor vehicle, in which at least one air treatment device is provided, at least one air channel extending through the air treatment device, and at least one air channel bypassing the air treatment device as well as at least two exit routes.
- the invention provides in this context that the different paths open into a space in such a way that each time an exit path is practically or essentially opposite one of the other paths, a device mobile around an axis being arranged in this space, which device has an air guiding element in the form of a channel and ensures, in defined positions, an air passage practically without pressure losses, between two channels opposite one of the other, and an air passage subjected to pressure losses between other facing channels.
- the invention makes it possible to use the same single space to guide the air in two different directions, by making the device pivot around an axis, for example central, or off-center.
- a configuration of one channel in another is thus provided so that these extend essentially parallel and thus allow a maximum air flow, for example in the defrosting mode, while in another defined position, a passage in the other of two air streams uncoupled from each other is possible, the two directions of flow can be for example perpendicular to each other 'other.
- a passage practically free from pressure losses is thus possible in the internal channel, which is defined by the channel-shaped air guiding element, for example from the air treatment device.
- an insulating engagement in at least one position between the air guiding element in the form of a channel and at least one channel, in particular with respect to two channels facing each other.
- a continuous air path can be formed between the air treatment device and the bottom part, so that a defined quantity of treated air can be diffused in the rear part regardless of the settings. air conditioning techniques of the front part.
- the air guide element in the form of a channel is advantageously provided with an opening which allows a bifurcation of the air out of the passage subjected to a pressure loss.
- the channel-shaped air guide element may preferably have at least two compartments, at least one of which can be closed, with the exception of the ends.
- the air treatment device would be a heating body, to produce a hot air path defined as far as the bottom region, which is flanked by another channel, which can be supplied with cooler air alongside the heated air, which is thus derived from the passage subjected to a pressure loss.
- the cross section of the air guide element in the form of a channel is practically constant, but does not however present at least any noticeable narrowing which could lead to a loss of pressure.
- the air guide element in the form of a channel is produced with a curvature, so that it can for example allow, in a defined position, a deflection of air upwards, and in another defined position, a deflection of the air downwards.
- the device movable around an axis comprises means for blocking at least one lane, in particular two lanes facing one another in at least one of the defined positions. In this way, it is for example possible to prevent air from reaching the bottom part, which is desirable in particular in situations where the maximum amount of air is required in the front part.
- the aforementioned means can be made in one piece with the air guide element in the form of a channel and form therewith, for example, an essentially cylindrical body. If an at least partial double wall is thus provided, the quality of the flow of the device can be improved for any defined positions and intermediate positions.
- the width of the channel-shaped air guiding element or also of the mobile device around the axis should advantageously be essentially equal in the direction of the axis to the width of at least one channel, in particular d 'a pair of tracks opposite one another.
- the width of the channel-shaped air guide element or of the device which can rotate around the axis in the direction of the axis corresponds essentially to between 15% and 85%, in particular between 20% and 40% of the width of a channel, in particular of a pair of facing channels, the range of 20% to 40% being in particular suitable for the case where one of the air outlet channels faceoff is provided for the bottom space or the foot space of a vehicle.
- the direction in which the device can be moved can extend both essentially horizontally, vertically or also at an angle.
- the term width should also be understood as a sum of widths, for example when there are two channels spaced from each other. In the case of two spaced channels, these could be flush laterally to the edges of the wider tracks, a wall of the channel or channels can also be formed by the housing itself.
- the invention allows the choice, for minimal space requirements, that two air flows can penetrate into each other while in another case, in another defined position, there is practically the entire cross section of flow, as if for example an air duct for the bottom part was no longer even present.
- Figure 1 illustrates a sectional view through an air guide housing according to a first preferred embodiment.
- Figure 2 illustrates a section through the channel-shaped air guide element shown in Figure 1.
- Figures 3 and 4 illustrate alternative embodiments of that illustrated in Figure 1, the air guide member in the form of a channel forming a closed channel with the exception of the ends.
- Figure 5 illustrates a detailed sectional view of the embodiments illustrated in Figures 3 and 4, in particular of a space 3 into which open the different airways.
- Figures 6 and 7 illustrate perspective representations of the detail view illustrated in Figure 5.
- Figure 8 illustrates a section through the channel-shaped air guide element contained in Figure 3 or Figure 4, along a plane II, as shown in Figure 5 and Figure 7 .
- FIG. 9 illustrates an improvement of the embodiment illustrated in FIG. 3 with means which make it possible to block two air channels.
- FIG. 10 illustrates yet another improvement of the embodiment illustrated in FIG. 5, in which a bifurcation is possible from the passage subjected to pressure losses.
- FIG. 11 illustrates another preferred embodiment, which combines the concepts of FIGS. 5 and 6, no means for blocking the channels being however provided.
- Figures 12 and 13 finally illustrate yet another preferred embodiment in two different defined positions, of the device movable around the axis, which contains, as an essentially cylindrical body formed in one piece, the guide element d air in channel form as well as the means for blocking at least one air channel.
- Figure 1 illustrates, in partial sectional view, an air guide housing as a preferred embodiment of the invention, which is part of a ventilation-heating device for a motor vehicle.
- a heat exchanger for heating 10 which can be supplied with engine coolant and an electric heating device 12 mounted downstream.
- the air supplied by a blower not shown can, after a possible passage through an evaporator - as long as an air conditioning system is also provided - pass as desired and in a controlled manner by a control valve A through the device air treatment and take an air path 20 extending through the air treatment device, or be guided in front of the air treatment device, and thus take an air path 30 bypassing the air treatment device, a respective proportional adjustment also being possible by the air control valve A.
- the channels 20 and 30 open into a space 3.
- an air channel 50 extends upwards to the diffusers of the front part of a motor vehicle, and another outlet channel from air 40 extends down and back towards the air diffusers in the bottom part.
- space 3 in which in principle the air flows exiting from channels 20 and 30 can mix and can be diffused towards channels 40 or 50, there is a device 1 which is mounted mobile, in this case, rotatable, around an axis 2.
- the device 1 comprises a channel-shaped air guiding element which comprises a channel wall 7 as well that two side walls not shown in this view. As illustrated, the device 1 can be arranged in two defined positions, which are indicated by the channel wall 7 for one position and the channel wall 7 'for the other position. Obviously, the device 1 could also form two lateral channels or several distributed channels.
- the channel wall 7 extends essentially parallel to the direction of flow. Due to the curvature of the channel wall 7, account is taken of the existing flow profile, so that, with the exception of the thickness of the material of the channel-shaped air guide element, no resistance to flow and therefore no loss of pressure takes place. In the position indicated by the reference number 7, a passage from track 20 to track 40 is on the contrary blocked or subjected to pressure losses.
- the wall of the channel extends in the position indicated by the reference number 7 ', so that a passage from the channel 20 towards the channel 40 can be carried out practically without loss of pressure.
- the width of the channel-shaped air guide element is less than the width of track 30 as well as track 50, as can be seen more clearly from FIG. 2, which shows a section perpendicular to the plane of the drawing of Figure 1 through the air guide member in the form of a channel.
- the channel-shaped air guide element mounted on the axis 2, is open in one direction, namely upwards, and comprises, in addition to the channel wall 7, side walls 5 and 6, where, for the illustrated embodiment, sufficient space is available laterally next to the walls 5 and 6 so that the air can pass from the track 30 to the track 50, in order to be able to ensure the air conditioning of the part before, regardless of the operating mode.
- a downwardly open channel could also be provided correspondingly.
- the axis illustrated 2 that although it is illustrated in the central position, it could also extend in an eccentric position, and also in another orientation, for example vertical instead of horizontal.
- the width of the channel-shaped air guide element corresponds to approximately 30% of the width of the channels 30 or 50, while it corresponds essentially to that of the channels 20 and 40.
- the embodiment illustrated in Figures 1 and 2 allows a parallel arrangement for example of a channel in another coaxial, between tracks 30 and 50 on the one hand, the air guide element in the form of a channel extending on the other hand in another defined position 7 'transversely to the passage between the track 30 and the track 50, and forming a passage free from pressure losses from the track 20 towards the track 40.
- the channel-shaped air guide element comprises, in addition to the channel wall 7 and the side walls 5 and 6, another channel wall 4, so that a closed channel except for the ends is defined, which can be hermetically engaged in a position with the track 20 and / or track 40, in order to form a continuous flow path from the air treatment device 10, 12 to the foot space in the bottom part, the front part also being able to be air-conditioned , because the air coming from channel 30 can flow forward at the level of the channel formed towards channel 50.
- the device 1 can easily be pivoted, so that the walls 4, 5, 6, 7 of the channel are arranged essentially parallel to the direction of flow between the channels 30 and 50, so that a practically non-shrinking cross-section is established between the has track 30 and track 50.
- FIG. 4 is distinguished from that of FIG. 3 in a decisive manner by the fact that the air outlet channel 40 can be supplied in addition via a fresh air channel 60. If in this way a transition practically free from loss of pressure takes place from the air path 20 to the air path 40 for the heat treated air, a temperature control can be obtained by mixing air therein. through the channel 60.
- FIG. 5 illustrates a detailed view relative to the space 3, into which the hot air supply path 20, the fresh air supply path 30 as well as the exhaust air paths 40 and 50 open out. , for each different air conditioning zone, this detail view corresponding to the representation of FIGS. 3 and 4.
- FIG. 5 To highlight the defined air passages penetrating into each other between the different air channels, the detail section illustrated in Figure 5 is illustrated in perspective in Figures 6 and 7, a passage practically free of pressure loss from track 20 to track 40 and a passage under pressure loss from track 30 to track 50 being illustrated as a defined position.
- the pressure loss when passing from track 30 to track 50 results essentially from the presence of the channel walls 7 and 4.
- the configuration chosen for the channel is chosen voluntarily with an essentially rectangular section, so that other surfaces in cross section could be easily represented with small modifications, such as for example round, elliptical or polygonal, the effect of the channel wall 7 as an incidence surface and therefore as a cause of the pressure reduction, which can be further reduced.
- FIG. 8 illustrates, as in FIG. 2, a partial section through the embodiments illustrated in FIGS. 3 and 4, and this along a section plane I-I, as indicated in the detailed views of FIGS. 5 and 7.
- Figure 9 illustrates yet another preferred embodiment which is similar to the shapes described above.
- additional means 8, 9 are however provided, which can block and free the channels 40 or 20.
- the movement of these means with the air guide element in the form of a channel 4, 5, 6 , 7 can be ordered coupled with or independently.
- the respective positions defined are on the one hand indicated by reference numbers without premium, and on the other hand by reference numbers with a premium.
- the closing means 8, 9 a leak towards the bottom part can be avoided in the case where a maximum evacuation of air in the front part is desired or necessary.
- the closure means 8 and 9 could also be configured separately, and can prevent a hot air leak.
- FIG. 10 illustrates another preferred embodiment of the air guide box according to the invention, the wall 7 mounted upstream from the point of view of the fluid technique of the air guide element in the form of a channel. being provided with an opening 11, which makes it possible to bypass or divert a part of the flow from channel 30 towards channel 40, in order to make available in the case of the embodiment described a slightly lower temperature in the region of background. Otherwise, the operation of the illustrated embodiment corresponds to that of FIG. 5.
- FIG. 11 is essentially a combination of the embodiments illustrated in FIGS. 9 and 10, however the means for blocking the channels have been omitted, although these can also be added.
- the channel-shaped air guide element forms two channels isolated from one another, one channel closed except for its ends, while the other channel has an opening 11 which allows a supply of fresh air into the bottom region.
- the device 1 can also be positioned so that there is an almost unobstructed passage of air from track 30 to track 50.
- Figures 12 and 13 illustrate another embodiment of the air guide housing according to the invention, in which the means 8, 9 for blocking the track 20 and / or the track 40 are made in one piece with the air guide element in the form of a channel and define an essentially cylindrical body as device 1.
- the operation corresponds essentially to that of the preceding embodiments.
- the position illustrated in FIG. 12 makes it possible to guide the air in a channel from the air treatment device to the region of the bottom, the air being able to pass from channel 30 towards channel 50 in front of the device 1, and this only at one side or, as in the embodiments described above, on both sides thereof.
- the tracks 20, 30 are blocked by the means 8, 9, the total cross section being essentially released for the air conditioning of the front part, namely both through the channel and also laterally in front of it, that is to say parallel to the plane of the drawing in front of the device 1.
- the air guiding element could also constitute one or two lateral channels, in which case a wall could be produced by sealing application with the housing itself.
