Technical Field

[0001] The invention relates to a heating device for an air handling unit, the heating device having at least a first structure group and a second structure group. In addition, the invention relates to an air handling unit having such a heating device. Background Art

[0002] In systems for air treatment, there are usually outlet valves, by means of which moist air and condensed water can be blown off.

[0003] In order to prevent the outlet valve from freezing under low temperature conditions, an electrically operated heating device is usually arranged near the valve. When the heating device is energized, the heating device body heats up and the housing area around the outlet valve is also heated up as a result.

[0004] Two different versions of such air handling systems are usually used here, wherein, in a first variant, the air dryer unit is not fastened to the core module or main module and the air handling unit has an external heating device, which is powered via a cable. In a second variant, the air dryer unit can be fastened to the core module or main module, wherein the heating device is placed in the air dryer unit and is powered by the control unit (ECU) of the core module.

[0005] In this second variant, parts of the heating device components need to be placed across the module boundaries in the air dryer unit with the outlet valve and in the core module with the control unit.

[0006] In order to avoid damage to the heating device components during transportation of the modules of the air treatment system, it is meaningful to divide the heating device components into at least two (sub)assembly groups, which are placed in the corresponding modules of the air treatment system and at most protrude or project from the corresponding modules to a certain extent or slightly.

[0007] In addition, the heating device components must not come out of the corresponding modularity during the assembly process. In addition, the interfaces between the heating device components must be protected against splash water in order to prevent electrical short circuits, corrosion and / or the like. Summary of the invention

In addition, the object of the present invention is to specify an air treatment system having such a heating device.

[0009] This object is achieved according to the invention by a heating device according to claim 1 and an air treatment system according to claim 12 .

[0010] According to this arrangement, a heating device for an air handling unit is constructed with at least one first structural group and a second structural group, wherein the first structural group has at least one receiving element and the second structural group has at least one fixing element.

[0050] Figure 4 Shown for assembly according to Figures 1 to 3 Cross-sectional views of different method steps of the first and second structural groups. DETAILED DESCRIPTION

[0051] Figure 1 A perspective view and a perspective sectional view of a first structural group 110 of a heating device 100 according to a first exemplary embodiment are shown.

[0052] according to Figure 1 , the first assembly is designed to include a receiving element 112 and a first line component 114 .

[0053] according to Figure 1 The first line element 114 shown is provided as an electrical (contact) pin.

[0054] The first conductor elements 114 may each have a chamfered section 114 at their tips.

[0055] The first line component 114 is surrounded by the receiving element 112 or is arranged in the receiving element 112 .

[0056] In particular, the receiving element 112 is formed as a recess in the sense of a female engagement structure for receiving a corresponding mating element, for example a male engagement structure. A fixing element in the sense of a joining structure.

[0057] The receiving element 112 is designed at its end side with a chamfered section 130 , in particular with an inner and substantially circumferential chamfered section 130 , in order to simplify the engagement with a corresponding counterpart, preferably a fastening element.

[0058] The receiving element 112 has at least one fastening element 160 .

[0059] The fastening element 160 can point outward in the sense of a circumferential direction in order to enable engagement in a housing or the like for fastening or interlacing on or along the first structural group 110 .

[0060] Furthermore, the receiving element 112 can have at least one orientation element 116 , for example in the form of a protruding or projecting lug, so that the first structural group 110 can be connected to the corresponding second structural group only within a certain angular range.

[0061] It is possible that the first structural group 110 or the receiving element 112 has a plurality of identical or different orientation elements 116, so that a connection to the first structural group can only be realized in one direction or within a certain angle range. In this sense, at least one orientation element allows a connection to the first structural group according to the key-and-lock principle.

[0062] The geometry, for example the outer contour, of the receiving element 112 and / or of the fixing element 122 can be designed in such a way that the first and second structural groups 110 ; 120 can only be connected when they are positioned in a certain orientation range or angle range relative to one another.

[0063] Preferably, the fastening element 160 can be designed to be at least partially elastic in order to enable a releasable intersection (in the sense of a non-positive and / or positive connection) along the first structural group 110 or the first module 210 to provide a loss prevention structure.

[0064] according to Figure 1 The first structural group 110 may have a sealing element 150 , which is preferably in the form of a sealing ring or an O-ring or the like. The sealing element 150 may be arranged along the outer circumference of the first structural group and may be placed on at least one fastening element 160 , for example.

[0065] Furthermore, the receiving element 112 can be designed to be at least partially elastically deformable, in particular can comprise an at least partially elastically deformable material.

[0066] Figure 2 A perspective view of the second structural group 120 of the heating device 100 according to the first embodiment is shown.

[0067] In particular, the second structural group 120 can be designed with a fixing element 122 , preferably in the sense of a male engagement structure.

[0068] The fastening element 122 can be constructed in one piece or in multiple pieces. Figure 2 The fixing element of the second structural group 122 is provided with an additional sleeve insert, in particular for accommodating the first and second line components 114 ; 124 .

[0069] according to Figure 2At least one second line component 124 extends along the second structure group 120 and is arranged or accommodated inside the fixing element 122 .

[0070] The fastening element 122 is designed with a chamfered section 130 , in particular in such a way that the introduction of the first conductor section 114 , which is preferably in the form of a (connecting) pin, is possible.

[0071] Therefore, the fixing element 122 with the chamfered section 130 can be used to fasten the second structural group, wherein a connection between the second line component 124 and the first line component 114 within the fixing element 122 can be achieved in an advantageous manner.

[0072] Figure 3 Show according to Figure 1 and Figure 2 120 of a heating device 100 in an assembled or combined state. In particular, the heating device 100 can be arranged as part of an air handling unit 200, such as an air dryer unit.

[0073] For example, the first structural group 110 may be disposed or arranged in a first module 210. For example, the first module 210 may be an air dryer module or a main module or a core module.

[0074] according to Figure 3 , the second structural group 120 can be set or arranged in the second module 220. For example, especially corresponding to the first module 210, the second module 220 can be a main module or a core module or an air dryer module.

[0075] The heating device 100 can be supplied with power via a control unit of a main module or core module along the first and second line components 114 ; 124 to be electrically connected to one another.

[0076] In particular, according to Figure 3 It is provided that, in the assembled state of the air handling unit 200 or the heating device 100 , the sealing element 150 can be pressed onto or between the first and / or second module 210 ; 220 , in particular so that a fluid-tight connection can be provided along the interface between the first and second modules 210 ; 220 .

[0077] In addition, from Figure 3 As can be seen in the figure, the fixing element 122 of the second structural group 120 is accommodated in the accommodation element 112 of the first structural group 110 of the heating device 100, so that an electrical contact can be provided between the first and second line components 114; 124. In particular, the first and second line components can be oriented and guided relative to each other in the accommodation element 122, so that a safe and reliable electrical contact can be achieved.

[0078] In the assembled state of the heating device 100 , the receiving element 112 and the corresponding fastening element 122 engage in one another, so that an electrical connection can be provided via the first and second line elements 114 ; 124 .

[0079] The fastening elements 160 of the first structural group 110 and / or the second structural group 120 of the heating device 100 can provide an anti-loss structure, in particular before, during and after assembling the first and second structural groups 110; 120. In this sense, the first and second structural groups 110; 120 can be retained in the first or second module 210; 220, respectively, so that the assembly or assembly of the heating device is facilitated.

[0080] Figure 4 Shown for assembly according to Figures 1 to 3 Cross-sectional views of different method steps of the first and second structural groups 110; 120 of the heating device 100.

[0081] In one step, the first structural group 110 and the second structural group 120 or the first and second modules 210 ; 220 are roughly oriented relative to each other.

[0082] As soon as the first contact between the receiving element 112 and the fixing element 122 is established, the fixing element and the receiving element can be slid relative to one another along the chamfered section 130 , so that a pre-positioning can be achieved for compensating for an offset in the radial direction.

[0083] Likewise, the first conductor element of the first structural group can have a chamfered section 140 , so that a sliding movement relative to the chamfered section of the fixing element 122 is possible.

[0084] In particular, the fixing element 122 and the receiving element 112 may be at least partially elastically deformable in order to facilitate assembly and orientation relative to one another.

[0085] As soon as the first line element 114 has been received or introduced into the fixing element 122 , the sealing element 150 can be pressed together by combining the first and second modules 210 ; 220 , so that a fluid-tight interface can be provided.

[0086] In summary, the invention provides a simple and reliable possibility for connecting two structural groups 110 ; 120 of a heating device 100 .

[0087] Depending on the geometric configuration of the structural groups 110 ; 120 , a correct orientation or positioning of the structural groups 110 ; 120 relative to one another can be ensured, for example by means of orientation elements 116 .

[0088] The configuration of the chamfered sections 130 ; 140 allows compensation of radial offsets of the structural groups relative to one another, so that a secure combination of the structural groups 110 ; 120 is ensured in order to enable an electrical connection along the line elements 114 ; 124 .

[0089] In this case, the structural assembly 110 ; 120 , in particular the receiving element 112 and / or the fixing element 122 , can be at least partially elastically deformable in order to be able to compensate for radial misalignments during assembly and to facilitate the joining process.

[0090] In addition, with the help of the fastening element 160, an anti-loss structure for the accommodating element 112 and / or the fixing element 122 can be provided, so that safe and reliable fastening inside the first and / or second module 210; 220 can be guaranteed before, during and after the combined heating device 100.
