Description

Technical Field

[0001] This invention relates to a temperature control device for adjusting the temperature of a workpiece, and more particularly to a temperature control device for heating the body of a motorized vehicle. The invention also relates to a corresponding method for adjusting the temperature of a workpiece. Background Technology

[0002] Temperature control devices, constructed as continuous dryers, are known in practice for heating the body of motorized vehicles. They typically involve a rhythmic or continuous conveying of the vehicle body.

[0003] Temperature control equipment used to heat the main body of a motor vehicle can also be called a dryer, and the temperature control chamber of this equipment is also called a dryer tunnel through which the main body of the motor vehicle is conveyed.

[0004] In known equipment, circulating air is circulated and regulated in temperature using circulating air components or temperature control devices. Related individual or integrated devices are known from the prior art.

[0005] For example, individual components or devices may be positioned above, below, or to the side of the dryer tunnel or temperature control chamber.

[0006] As for the heat source used to heat the circulating air, direct or indirect burner heating, electric heating, or clean gas heating can be achieved, for example, when using one or more heat exchangers.

[0007] In contrast, in an integrated arrangement, the temperature control unit or circulating air assembly is located on the same plane as the temperature control room or dryer tunnel.

[0008] In this configuration, the fans for guiding the recirculated air can be arranged on either side of the dryer tunnel, with reference to the direction of airflow. Alternatively, the fans can be pushed into the dryer tunnel from above, thereby aligning the impeller axis vertically in the case of a radial-flow fan.

[0009] In the case of integrated recirculating air components or temperature control devices, it has been preferred to arrange the heat source for temperature control of the recirculating air on both sides of the temperature control chamber or dryer tunnel, wherein in addition to the combustion chamber, the clean gas duct can also be used as a radiation source for heating the recirculating air.

[0010] The recirculated air supply in the temperature control chamber or dryer tunnel can be carried out on both sides or on one side, depending on the direction of transport. In the latter case, a portion of the recirculated air is transferred from one side of the temperature control equipment where the recirculated air assembly or temperature control device is arranged via a connecting passage or bridging passage (Überwurfkanal) or the top of the connecting chamber or bridging passage to the other side of the temperature control equipment.

[0011] The return of recirculated air from the conditioning or dryer tunnel can be guided from both sides or from one side.

[0012] With recirculated air return guidance on both sides, recirculated air can be returned from the temperature-regulating chamber at the beginning or end of the temperature-regulating chamber or its section, for example, via the side walls or via the bottom or top areas. Recirculated air return guidance or exit can also be achieved in the middle of the temperature-regulating chamber.

[0013] Regarding the return air guide on one side, referring to the conveying direction, a return guide in the middle of the temperature control chamber on the bottom side or at least near the bottom is preferred.

[0014] The arrangement of the previously described circulating air assembly or temperature control device at the temperature control equipment is accompanied by the corresponding space requirements of the temperature control equipment, especially the space requirements in the width direction of the equipment, which is horizontal and perpendicular to the conveying direction orientation. Summary of the Invention

[0015] Therefore, the object of the present invention is to provide a temperature control device that has small space requirements and is designed in a resource-optimized manner.

[0016] According to the present invention, this objective is achieved by a temperature control device having the features of claim 1 for controlling the temperature of a workpiece.

[0017] Temperature control equipment, especially equipment used for heating the main body of motorized vehicles.

[0018] Temperature control equipment includes:

[0019] - At least two temperature control modules, arranged sequentially in the conveying direction; and

[0020] - At least one power module for circulating and regulating the temperature of recirculated air, the power module being arranged at least segmentally between at least two temperature regulating modules.

[0021] The temperature control chamber is constructed by at least two temperature control modules and at least one power module, through which workpieces can be conveyed in the conveying direction to be temperature-controlled with circulating air.

[0022] This invention is based on the concept that the small width of the temperature control device or module allows two temperature control devices to be arranged side-by-side within a standard 12-meter hall grid, enabling the design of a dual dryer. Furthermore, the lateral integration of the temperature control device facilitates maintenance. For this purpose, a power module with a preferably lateral temperature control device is integrated as an intermediate section between the two temperature control modules, connecting them, with reference to the workpiece conveying direction. Advantageously, the temperature control device does not protrude beyond, or at least only slightly protrudes beyond, the width of the temperature control module. Moreover, the arrangement of the temperature control device on one side of the temperature control device allows for a low overall structural height of the entire temperature control system within a single building floor.

[0023] The temperature control device according to the invention is characterized by the arrangement of a fan on one side, together with a plurality of temperature control units preferably configured as electric heating units or thermal registers, on one side of the temperature control device, i.e., the so-called operating side, with the fan's axis horizontal relative to the hall floor and oriented perpendicular to the conveying direction. This feature is also a necessary prerequisite for constructing dual dryer lines or for installation on adjacent hall walls or other similar interfering profiles.

[0024] Advantageous of the temperature control device according to the invention is that, by using the temperature control module in conjunction with the central power module, the entire temperature control device can be modularized into several standardized modules or sections.

[0025] Correspondingly, a standardized temperature control module with a fixed extension (longitudinal extension) in the conveying direction can be combined with a power module whose longitudinal extension is variable. The variable longitudinal extension of the power module allows for the realization of a specific cycle length for the main body. Conversely, the power module can also have a fixed longitudinal extension, and the temperature control module can be configured to have a variable longitudinal extension for this purpose.

[0026] It can also be envisioned that for longer workpieces, the longitudinal extension of the temperature control equipment can be extended by using an intermediate module.

[0027] This leads to a low-cost design for a temperature control device, in which, on the one hand, circulating air can be used to blow through the conveyed workpiece evenly and symmetrically, and on the other hand, circulating air can be drawn out from the temperature control chamber of the temperature control device via an exhaust section in the bottom region, with reference to the conveying direction, in a central or centered manner.

[0028] The temperature control module, constructed together with the power module, in the temperature control chamber or dryer tunnel enables the provision of a standard cycle length for temperature control of the workpiece. This can also be referred to as providing a so-called cycle station, which preferably corresponds to the common length or longitudinal extension of the workpiece constructed as the body of a motorized vehicle.

[0029] Accordingly, the cycle station constructed by the temperature control module and / or the temperature control module and the power module is set in the longitudinal direction to allow the workpiece to be fully received.

[0030] Advantageously, at least one cycle station of the temperature regulating chamber, i.e., in particular the temporary position of the workpiece during its transport along the conveying direction, extends at least segmentally into the power module, thereby reducing the extension of the temperature regulating module adjacent to the power module in the conveying direction. In other words, each temperature regulating module directly adjacent to the power module is preferably shorter than the cycle station of the workpiece to be regulated, such as the body of a motorized vehicle to be heated, because the corresponding cycle station protrudes at least segmentally into the power module.

[0031] The intermittent operation or intermittent operation mode of temperature control equipment has the following advantages over continuous operation: temperature-controlled circulating air can be used to blow or direct the workpiece at the temporary stopping position of the workpiece, while in continuous operation, the workpiece is continuously conveyed through the equipment without temporary stops.

[0032] For example, a temperature control device with two temperature control modules and a power module arranged therebetween has a total longitudinal extension of 11m to provide two cycle stations for a workpiece that is constructed as the body of a motorized vehicle and has a length of up to 5m.

[0033] It should be understood that the temperature control device according to the invention is not limited to the number of two sequentially arranged temperature control modules, and other combinations of temperature control modules are possible. Correspondingly, two to six or more temperature control modules may also be arranged sequentially, wherein all possible combinations can be configured as heating zones, holding zones, or cooling zones. Power modules may be arranged or integrated between any two adjacent temperature control modules, but power modules are preferably centrally arranged in the corresponding zones. It should also not be excluded that power modules may be arranged at the beginning or end of the temperature control device with reference to the conveying direction.

[0034] Temperature control devices, especially heating and / or cooling devices, or integrated therein.

[0035] It may be advantageous for the temperature control device to have at least one device housing that demarcates or surrounds the temperature control module and / or power module relative to the environment of the temperature control device.

[0036] The temperature control module and the power module are preferably constructed together in a common device housing.

[0037] It can also be specified that at least one power module includes at least one temperature control device.

[0038] Advantageously, at least one temperature regulating device is arranged on the side of the temperature regulating chamber with reference to the conveying direction, and preferably, at least one temperature regulating device is arranged in the middle area of ​​the temperature regulating chamber with reference to the conveying direction.

[0039] Another advantage is that at least one power module includes a connection channel and / or a connection chamber.

[0040] In the case of a temperature control device arranged on one side, i.e., in the temperature control chamber or temperature control equipment arranged on only one side, what is required for uniform and symmetrical blowing of the workpiece in the temperature control chamber is that a portion of the temperature-controlled circulating air can be transported to the other side of the temperature control chamber.

[0041] It may be advantageous to configure the power module and two temperature control modules directly connected to the power module for two cycle stations of preferably two workpieces, wherein each of these cycle stations extends at least segmentally into the power module with reference to the conveying direction.

[0042] It can also be specified that the temperature control equipment has at least two different temperature zones along the conveying direction.

[0043] In another design of the present invention, the temperature control device may be specified to have at least one heating zone and / or at least one holding zone.

[0044] The advantage is that the district can...

[0045] a) One or more blocking elements and / or

[0046] b) One or more airlocks

[0047] Separated in atmosphere and / or heat from each other and / or from the environment of the temperature control equipment.

[0048] Barrier elements can be physical barriers, such as sliding doors or vertically movable door panels.

[0049] In addition, the barrier element can be at least partially thermally insulated.

[0050] In the open position of the barrier element, the barrier element can preferably be located in a recess, cavity, compartment or temporary position above, below or to the side of the temperature control chamber, and can be moved from there into the temperature control chamber to separate the area.

[0051] The barrier element can be a single piece or multiple pieces.

[0052] In the case of multi-piece barrier elements, the sub-elements can travel in opposite directions or in parallel directions.

[0053] When the cycle time is long enough, it is preferable to provide one or more blocking elements between at least two zones, wherein the cycle time is particularly the time during which the workpiece is processed in the zone.

[0054] For example, this is the case if the cycle time is greater than or equal to the time required for the closing and opening processes of the blocking element. Particularly preferred is that the cycle time for workpiece handling is equal to or greater than five times the time required for the closing and opening processes of the blocking element.

[0055] Furthermore, airlocks are constructed as barriers in terms of flow technology to separate the atmosphere and / or heat between corresponding zones or process areas of temperature control equipment.

[0056] Another advantage is that the airlock is constructed vertically and matches the contour of the workpiece.

[0057] Preferably, the airlock is constructed in the form of a vertical double air curtain (Doppelsilhouette) that matches the contour of the workpiece.

[0058] These two air curtains may be the same or different from each other in terms of their temperature and / or their proportion of fresh and recirculated air.

[0059] The airlock is particularly positioned between two cycle stations, where workpieces are preferably processed separately.

[0060] The air curtain or air screen of the airlock preferably extends across the entire width of the temperature-regulating chamber.

[0061] In the case of process zones that can be configured as, for example, pre-dryers, main dryers, or cooling zones and have temperature classifications with different temperature levels, an airlock is preferably provided between every two temperature zones.

[0062] An airlock can be constructed from the top, one or two side walls, or bottom of the conditioning chamber, specifically to bring air into the conditioning chamber from these locations.

[0063] Advantageously, the airlock from the slit nozzles arranged at the top of the regulating chamber is directed relative to the warmer atmosphere at an angle of 20 to 40 degrees relative to the direction of gravity, preferably approximately 30 degrees, i.e., toward the adjacent area with a higher temperature. This type of airlock thus generates pulses that resist the thermal pressure of the adjacent area with a higher temperature.

[0064] Ideally, the airlock area should be kept clear or moved freely by the rapid transfer of conveying equipment, so that the air jet of the airlock is not disturbed by the workpieces lingering there.

[0065] In this configuration, the dammed air is drawn into the conditioning chamber, for example, between two plates that conform to the contour of the workpiece traveling longitudinally or laterally. The dammed air flows vertically downwards and is drawn out of the conditioning chamber via a bottom suction section.

[0066] The air in the airlock preferably flows downward and can be drawn out, for example, in the bottom region of the conditioning chamber via two bottom suction openings arranged sequentially along the conveying direction. These bottom suction openings can be configured as bottom suction slots and extend across the entire width of the conditioning chamber, i.e., transversely to the conveying direction.

[0067] However, it is also conceivable that the air in the sluice gate flows upward against gravity and is drawn out in the top region of the sluice gate.

[0068] However, air can also pass through the air conditioning chamber in the horizontal direction, that is, it flows into the chamber from one side wall and is drawn out or sucked out in the area of ​​the opposite side wall.

[0069] The constructed air curtain or air screen preferably extends substantially perpendicular to the conveying direction of the workpiece.

[0070] Airlocks can be operated with fresh air, recirculated air, or a mixture of recirculated and fresh air.

[0071] It can also be stipulated that the airlock upstream of the regulating chamber has at least one electric thermal register, so that it can be used for

[0072] a) Bring the preheated gate air (fresh air or recirculated air or a mixture of both) to the rated temperature; or

[0073] b) Bring fresh air from the environment of the temperature-controlled room or the hall where the temperature-controlled room is located to the rated temperature near the gate.

[0074] This avoids the cumbersome air passage from the central air heater to the airlock.

[0075] Fresh air channels can also be provided, especially for the supply of fresh air to the inlet airlock in the inlet or entrance of the temperature control room and / or the supply of fresh air to the outlet airlock in the exit or exit of the temperature control room.

[0076] The fresh air channel is preferably guided along one side of the temperature control device, with reference to the delivery direction.

[0077] On this side of the temperature control device, the fresh air passage is particularly arranged on and / or above one or more pressure chambers.

[0078] Preferably, the fresh air channel is arranged on one side of the temperature control device, which also houses the power module.

[0079] The fresh air passage is preferably guided through a connecting passage that transfers circulating air from the pressure chamber from one side of the temperature control device to the opposite side without the temperature control device.

[0080] To facilitate the crossing of the connecting channel, the fresh air passage has a particularly reduced cross-section in the section through which it is guided, ensuring that sufficient circulating air can be guided or directed to the other side of the temperature control unit via the connecting channel.

[0081] The fresh air guided in the fresh air channel and the recirculated air guided in the connecting channel are preferably separated from each other in terms of fluid action, that is, especially in the area traversed by the channel, there is no mixing of fresh air and recirculated air.

[0082] The connecting passage may have a widening or extension in the direction toward the conditioning chamber during the transition from the pressure chamber to its horizontal section on the conditioning chamber, with the fresh air passage arranged on and / or above the pressure chamber. This widening or extension corresponds to the shape of the fresh air passage with a reduced cross-section in this area and at least approximately compensates for the volume reduction caused by the fresh air passage.

[0083] Alternatively or supplementally, the connecting passage may extend in the transition section with a ramp or at an angle, preferably at a 45-degree angle to the side wall and / or top wall of the temperature regulating chamber.

[0084] Another advantage is that the fresh air passage is not guided through the connecting passage, but rather guided past the connecting passage in a manner with a reduced cross-section.

[0085] Preferably, the fresh air channel does not protrude beyond the power module in the lateral direction.

[0086] Alternatively or supplementally, the fresh air channel preferably does not protrude beyond the connection channel of the power module in height.

[0087] This type of integration or arrangement of fresh air channels allows the channel load to be discharged through the equipment housing, eliminating the need for additional channel suspension components.

[0088] Furthermore, this type of air passage becomes part of the module through this type of integration, thus making separate thermal insulation optional.

[0089] It can also be stipulated that at least one compensation device be provided for every two modules to absorb thermal expansion in the conveying direction.

[0090] Advantageously, in this case, a metal compensator or fabric compensator with bellows can be used, which is welded or screwed between the two zones or modules.

[0091] It may be advantageous for at least one temperature control module and / or at least one power module to be supported on at least one fixed base, wherein the fixed base is preferably arranged below the respective module.

[0092] For the controlled elongation behavior of modules in temperature-controlled equipment at operating temperatures, which aims to avoid mechanical overload of metal sheet structures or welded connections, it is advantageous to set a fixed base or fixing point.

[0093] It is advantageous that the extension of each module in the conveying direction and laterally to the conveying direction is feasible.

[0094] The fixing points or fixing bases of the sequentially arranged modules are preferably aligned along a common line in the conveying direction. The fixing bases of the modules are also preferably aligned along a common line in the transverse direction, i.e., transverse to the conveying direction.

[0095] In the case of power modules, it is advantageous that the mounting base is located below the fan of the temperature control device and thus below the area with the maximum surface load.

[0096] It can be specified that at least one heating zone includes a power module and two temperature control modules, wherein at least one heating zone may optionally include at least two intermediate modules for extending the temperature control chamber.

[0097] Furthermore, it can be specified that at least one holding zone includes a power module and four temperature control modules, the power module being preferably centrally arranged in the at least one holding zone with reference to the conveying direction, wherein the at least one holding zone may optionally include at least two intermediate modules for extending the temperature control zone.

[0098] Advantageously, at least one heating zone has [a feature] in the conveying direction.

[0099] a) 9m to 12m, preferably 11m, or

[0100] b) 12m to 14m, preferably 13m

[0101] An extension of.

[0102] A further advantage is that at least one holding area has in the conveying direction

[0103] a) 20m to 24m, preferably 22m, or

[0104] b) 24m to 28m, preferably 26m

[0105] An extension of.

[0106] In addition, the temperature control device may also include a cooling zone, which preferably does not have a power module.

[0107] However, it is also conceivable that the corresponding power modules are used as cascaded fans in multiple sequentially arranged cooling zones, where the power modules in this case basically include fans and connecting channels, but do not include heat sources or heat supply units.

[0108] In the case of cascaded ventilation between multiple cooling zones, for example, fresh air is supplied to the first cooling zone along the conveying direction and enters its corresponding pressure chamber. The fresh air is then conveyed through this pressure chamber to the temperature-regulating chamber section of the first cooling zone, where it is drawn out in the bottom region of the corresponding temperature-regulating chamber section by the fan of the power module of the first cooling zone. The drawn-out recirculated air from the first cooling zone is then introduced into the pressure chamber of the second cooling zone arranged downstream along the conveying direction, and via it reaches the temperature-regulating chamber section of the second cooling zone. The recirculated air from this temperature-regulating chamber section is also drawn out in the bottom region by the fan of the power module of the second cooling zone and supplied to the pressure chamber of the next cooling zone arranged downstream along the conveying direction. That is, the corresponding recirculated air from the temperature-regulating chamber of the last cooling zone in this sequence of the cascaded cooling zone network is drawn out from the temperature-regulating device as exhaust air.

[0109] It can also be stipulated that pressure chambers are constructed on both sides of the temperature regulation chamber, through which circulating air can be introduced into the temperature regulation chamber.

[0110] Therefore, each pressure chamber is constructed as a chamber that is at least substantially continuous on the side of the pressure chamber by temperature-regulating modules arranged in sequence.

[0111] It may be advantageous to have at least one temperature control device arranged at least in sections within the pressure chamber.

[0112] By integrating the temperature control device into the pressure chamber of the temperature control equipment, the width of the temperature control equipment can be significantly reduced, wherein, as stated below, which components or parts of the temperature control device are preferably arranged in the pressure chamber.

[0113] Another advantage is that the pressure chambers are interconnected by means of connecting channels and / or connecting chambers in a fluid-driven manner.

[0114] The connecting channel or connecting chamber can be arranged on the temperature control module, through which circulating air is guided to another pressure chamber. However, it is also conceivable that it be arranged inside the temperature control module or as part of the intermediate thickness inside the temperature control module.

[0115] It can be envisioned that the holding area has a pressure chamber only on one side of the temperature control device and accordingly does not require a connecting channel.

[0116] In another embodiment of the invention, it may be specified that at least one temperature regulating device protrudes beyond the width of the temperature regulating module by less than approximately 25%, preferably 20%, and particularly preferably 10% of the width of the temperature regulating module, the width of which is preferably horizontal and oriented perpendicular to the conveying direction.

[0117] This can be achieved by slightly protruding the temperature control device in the width direction of the temperature control module or temperature control equipment. Two temperature control devices can be arranged side by side in a standard hall grid to realize dual temperature control devices or dual dryers.

[0118] It can also be specified that at least one temperature control device includes at least one ventilator.

[0119] Advantageously, the ventilator is constructed as a radial flow ventilator.

[0120] The fan axis is preferably oriented horizontally and / or perpendicular to the conveying direction.

[0121] The ventilation fan is preferably located in the lower half of the temperature control device or equipment, especially in the lower third.

[0122] The fan can be removed more easily due to its low profile.

[0123] The installation depth of the ventilator is defined by the distance from the side wall of the temperature control chamber to the outer wall of the temperature control device or equipment. In other words, the installation depth of the ventilator is defined by the width of the pressure chamber in which the ventilator is integrated. In the ventilator, this measurement corresponds to the distance from the ventilator nozzle to the inside of the ventilator's isolation box (Isolierkassette), that is, the suction nozzle and ventilator wheel are arranged in the pressure chamber.

[0124] The suction nozzles of the ventilator can retract relative to the side wall of the temperature regulating chamber, i.e., spaced apart in the width direction of the temperature regulating module. In this case, a transition channel element is arranged between the side wall of the temperature regulating chamber and the frame housing of the suction nozzle, through which the circulating air drawn from the temperature regulating chamber is guided from the side wall of the temperature regulating chamber to the suction nozzle. This transition channel element is also referred to below as the suction chamber.

[0125] A chamber radially surrounding the ventilator within the pressure chamber forms a pretreatment chamber for the recirculated air exiting the ventilator. It can be envisioned that the pretreatment chamber is spatially demarcated within the corresponding pressure chamber.

[0126] The distance from the lower edge of the fan impeller to the bottom of the pretreatment chamber is preferably 10% and particularly preferably 75% of the fan impeller diameter.

[0127] In another design of the invention, it can be specified that the dimensions of the ventilators in the heating zone and the holding zone are set to be at least approximately the same.

[0128] In the context of the same construction method, it is advantageous that the size of the ventilators integrated in the heating zone and the holding zone is set to be the same, that is, in particular, the same ventilators are used.

[0129] The fans are preferably corresponding to each other in terms of their impeller size, their fan chamber and / or their fan flange.

[0130] Since different zones of the temperature control equipment require different air volumes, they are preferably operated at different speeds, wherein the speed of the fan motor is preferably controlled and / or regulated via a frequency converter.

[0131] For example, the circulating air volume flow rate is 40,000 m³ / h to 60,000 m³ / h, preferably 45,000 m³ / h, and the fan speed of the temperature control device in the heating zone is 45 Hz to 55 Hz, preferably 50 Hz.

[0132] In contrast, for example, the circulating air volume flow rate is 45,000 m³ / h to 70,000 m³ / h, preferably 60,000 m³ / h, and the fan speed of the temperature control device in the holding zone is 55 Hz to 70 Hz, preferably 63 Hz.

[0133] Because different shaft powers of the fans are required to achieve these volumetric flow rates, all motors of the circulating air fans can be designed to the maximum shaft power, or motors of different sizes can be used for fans in different zones.

[0134] For example, the motor power of the fan used in the heating zone can be from 15kW to 25kW, preferably 18.5kW, and the motor power of the fan used in the holding zone can be from 30kW to 45kW, preferably 37kW.

[0135] Another advantage is that at least one temperature control device includes at least one temperature control unit, preferably at least three temperature control units, which in particular are electric heating units.

[0136] The temperature control unit is introduced horizontally and perpendicular to the conveying direction through the outer wall of the power module or temperature control device of the temperature control equipment, at least in sections, into the pretreatment chamber surrounding the fan, and is also fastened to the outer wall by flange connections. The insertion depth of the temperature control unit into the pretreatment chamber or pressure chamber roughly corresponds to the depth of the fan impeller, i.e., its extension in the width direction of the temperature control equipment or temperature control module.

[0137] In another design of the invention, each temperature control unit may have multiple heating elements, which are arranged at least segmentally, and preferably at least substantially completely, inside the same pressure chamber.

[0138] It can also be specified that at least one first temperature control unit is arranged above the fan, and at least two second temperature control units are arranged on different sides of the fan with reference to a vertical plane parallel to the conveying direction.

[0139] The cross-shaped arrangement of the temperature control units around the fan ensures uniform airflow to these units. Ideally, the circulating airflow overflowing radially from the fan strikes the temperature control units perpendicularly.

[0140] Preferably, the center point of the second temperature control unit is located above the impeller axis of the fan.

[0141] It may be advantageous that the flow cross-section of at least one first temperature regulating unit corresponds to at least approximately 25%, preferably 50%, and particularly preferably 100% of the flow cross-section of at least two second temperature regulating units.

[0142] This at least approximately ensures that the two pressure chambers can be supplied with similar proportions of temperature-controlled circulating air.

[0143] It is also advantageous that at least one first temperature control unit provides at least approximately 25%, preferably 35%, and particularly preferably 50% of the heating power of the temperature control device, and at least two second temperature control units respectively provide at least approximately 10%, preferably 15%, and particularly preferably 25% of the heating power of the temperature control device.

[0144] The power module's production power, i.e., the power during production, for example...

[0145] a) For heating zones with two cycles, between 100kW and 350kW, and

[0146] b) For a holding zone with four beats, the power is between 50kW and 200kW.

[0147] Therefore, the temperature-controlled circulating air fractions guided or delivered to the two pressure chambers achieve similar temperature levels.

[0148] In another embodiment of the invention, at least one temperature control device may be specified to include a motor, particularly an electric motor, which drives a fan, wherein preferably the motor is arranged at least substantially entirely outside the temperature control module.

[0149] Thus, for example, the extension of the motor in the width direction of the temperature control device or temperature control module determines the width of the entire temperature control device.

[0150] It can also be specified that at least one guiding element, especially a guiding plate, is arranged downstream of the ventilator to guide the circulating air to at least one temperature control unit.

[0151] Furthermore, it is advantageous to arrange the guiding elements in the corner region of the pretreatment chamber, or to demarcate the entire pretreatment chamber from the surrounding pressure chamber through a flow-optimized shell.

[0152] Advantageously, recirculated air can be drawn out from the bottom side of the temperature-controlled chamber.

[0153] Another advantage is that the circulating air from the conditioning chamber can be drawn out of the conditioning chamber by means of a return guide channel, wherein the return guide channel is preferably constructed in a funnel shape at least in sections on the outlet side to increase the flow cross section.

[0154] Preferably, the circulating air return guide or circulating air extraction is started in the area between the two temperature control modules, that is, between the two workpieces to be temperature controlled, thereby supporting uniform and symmetrical blowing of the workpieces.

[0155] Another advantage is that the suction opening or return guide channel inlet is arranged between the two branches of the conveyor, which will be described later, thereby supporting symmetrical blowing of the workpiece.

[0156] The circulating air can preferably be drawn from the temperature-controlled chamber on either side of the conveying device or on one side of the conveying device.

[0157] Alternatively or supplementally, recirculated air may be drawn from the regulating chamber in the center, with reference to the conveying direction, and / or drawn from the regulating chamber between every two conveying devices arranged sequentially in the regulating chamber along the conveying direction.

[0158] By drawing circulating air from the center of the temperature control chamber at the height of the power module's temperature control device between two workpieces to be processed or between two cycles and / or with reference to the conveying direction, it is possible to ensure that the circulating air blows evenly and symmetrically onto the workpieces, as the circulating air flowing into the temperature control chamber is less likely to be deflected than when it is drawn or sucked out near the side wall. Furthermore, any dirt and dust that may be present is sucked out near the bottom, thus ensuring that the processed workpieces are not contaminated by swirling dirt and dust.

[0159] Furthermore, when the exit is made in the center, there is no risk that the door will be sucked up and potentially damaged in the temperature control room of the workpiece which is constructed as the main body of the motorized vehicle.

[0160] In another embodiment of the invention, it can be specified that the circulating air can be drawn out obliquely upward from the return guide channel at least in sections.

[0161] It can also be stipulated that the suction chamber is located upstream of the ventilator.

[0162] The suction chamber is preferably constructed when the frame housing of the suction nozzle of the ventilator is spaced apart from the corresponding side wall of the temperature control chamber and a transition channel element is arranged in the gap for bridging.

[0163] It is advantageous to position the suction chamber between the ventilator and the return guide channel.

[0164] It can also be specified that the return guide channel is constructed as a suction box.

[0165] The suction box preferably connects a circular fan suction opening to a square suction opening in a temperature-controlled chamber located in the area of ​​the conveying device, in order to achieve low flow rate and low pressure loss at the suction or outlet.

[0166] The suction box specifically includes two forming elements.

[0167] The first forming element is preferably a wedge-shaped box element with double bevels, adjacent to a circular ventilator suction opening.

[0168] The first inclined plane preferably forms an angle of approximately 20 degrees with a vertical line located in a vertical plane perpendicular to the conveying direction.

[0169] Furthermore, the first inclined surface extends from directly above the circular ventilator suction opening toward the temperature-controlled chamber, wherein the first inclined surface is preferably spaced 10 cm to 20 cm, preferably 15 cm, from the associated sidewall. Particularly in the upper region, the first inclined surface is sufficiently spaced from the side or door of the workpiece, which is constructed as the main body of a motorized transport vehicle, for example, by a space of 5 cm to 15 cm, preferably 10 cm. In the lower region, the first inclined surface is preferably sufficiently spaced from the workpiece carrier or carriage.

[0170] The second inclined plane is preferably at a 45-degree angle to a vertical line located in a vertical plane in the direction of the conveying equipment.

[0171] The second inclined plane widens the box element downwards in the direction of the conveying equipment and in the opposite direction of the conveying equipment. Preferably, the widening, which begins at the height of the fan axis, widens the box element, for example, from one-third to two-thirds of the power module width, where the power module width is preferably understood here as an extension or extension of the power module in the conveying direction.

[0172] The second forming element is preferably a square box element attached to a wedge-shaped box element.

[0173] The second forming element preferably extends from the side wall of the conditioning chamber to the conveying device and has approximately the same width as the power module. In height, the second forming element preferably extends from the bottom plate or bottom wall of the power module to the lower edge of the workpiece carrier or carriage, on which the workpiece is preferably conveyed through the conditioning chamber.

[0174] Roller conveyors or hybrid conveyors with chains and rollers are particularly suitable for suction boxes because they do not have a return section, as this provides a sufficiently large cross-section for air suction or extraction below the carrier profile of the conveyor or conveyor without raising the entire conveyor in the temperature control chamber and / or in the area at the interface with external conveying equipment.

[0175] Furthermore, the connecting passage and / or connecting chamber has a width taken in the horizontal direction and parallel to the conveying direction, which at least approximately corresponds to the extension of the fan or the first temperature control unit in the conveying direction.

[0176] Therefore, on the one hand, uniform overflow or through-flow of the first temperature regulating unit, or more precisely, the heating element of the first temperature regulating unit, should be achieved, and on the other hand, uniform flow guidance of circulating air from one side to the other side of the temperature regulating device should be achieved.

[0177] Advantageously, a guiding element is provided in the turning area at the transition from one pressure chamber to the connecting channel and from the connecting channel to another pressure chamber, which prevents or at least minimizes flow separation or backflow when switching between vertical and horizontal flow.

[0178] It can also be stipulated that workpieces can be transported through the temperature control room using a conveyor device.

[0179] In one embodiment of the invention, it may be specified that at least one conveying device has at least one section with an incline.

[0180] The conveying device is preferably placed or integrated into the temperature control equipment after the temperature control module and the power module are interconnected, wherein the conveying device preferably extends through all the connected modules.

[0181] In long temperature-controlled rooms, the conveying system can also be segmented, consisting of multiple separate sections or branches, each with its own drive and, for example, a separate loading station (Spannstation).

[0182] The conveying device enables the cyclical transport of workpieces, in which the workpieces are optimally oriented toward the circulating air introduced into the temperature control chamber.

[0183] The conveying device is therefore able to transport workpieces from one cycle station to another along the conveying direction.

[0184] Between two cycles, that is, when a workpiece is further conveyed from one temperature control module to the next temperature control module along the conveying direction, each workpiece passes through the temperature control device arranged on the side of the power module, as long as the temperature control module is directly adjacent to or connected to the power module.

[0185] The conveying device preferably includes at least two conveying mechanisms or conveying branches, which are oriented at least substantially parallel to each other and parallel to the conveying direction.

[0186] The conveying device is preferably designed such that the return guide channel is guided through the underside of the conveying mechanism, which is arranged close to the temperature control device or the ventilator.

[0187] It is also beneficial that the conveying device includes a chain conveyor and / or a roller conveyor.

[0188] Another advantage is that at least one conveyor is passable.

[0189] It is advantageous to install chain conveyors and / or roller conveyors in the heating and / or holding zones, while roller conveyors can be installed in the cooling zones.

[0190] For example, a conveyor can be provided for each zone or module. However, it is also conceivable that the conveyor will transport the workpiece through at least two zones or modules.

[0191] Especially when two adjacent zones are separated in terms of atmosphere and / or heat by one or more barrier elements, conveying devices are arranged upstream and downstream of one or more barrier elements respectively, referring to the conveying direction.

[0192] Therefore, the conveying device is interrupted in the area of ​​one or more blocking elements, and a transfer occurs from the upstream conveying device to the downstream conveying device when the blocking element is in its open position.

[0193] Alternatively, a hybrid conveyor system can be installed, which is constructed as a roller conveyor with a continuous conveyor chain, thereby eliminating the need to change the conveyor system, and in particular, the chain, between two zones or modules. This is especially possible when zones are separated in terms of atmosphere and / or heat by one or more airlocks.

[0194] Correspondingly, the essentially vertical air curtain is preferably constructed between two cycle stations or workpieces to be processed, thereby eliminating the need for free movement of the area where airlocks are required.

[0195] In cases where the free cross-sectional area below the conveying device or conveying equipment is insufficient to allow for the extraction or reabsorption of circulating air from the conditioning chamber between the two branches of the conveying device, it is advantageous to achieve the required conveying device height by having the conveying mechanism chain and / or conveying mechanism rollers guided along ramps in the area at the entrance or inlet of the conditioning chamber and in the area at the exit or outlet from the conditioning chamber.

[0196] This diagonal travel eliminates the need for complex elevator stations at the interfaces with preceding and following conveyor devices or equipment.

[0197] Since one of the pressure chambers is interrupted by the temperature control device and therefore it is impossible to pass through the pressure chamber unobstructed in the transport direction for maintenance or control work, a pressure chamber door is provided in the shell wall and / or in the side wall of the temperature control chamber.

[0198] Advantages of the latter situation are that the conveyor is accessible inside the temperature-controlled chamber. This can be achieved, for example, by covering with sheet metal and / or grating.

[0199] In long temperature-controlled rooms, the conveying system can be segmented, consisting of multiple separate sections or branches, each with its own drive and, for example, a separate loading station.

[0200] The conveying device is particularly capable of enabling cycle-type transport of workpieces, wherein the workpieces are optimally oriented towards the circulating air introduced into the temperature control chamber. Therefore, the conveying device can transport workpieces from cycle-type station to cycle-type station in the transport direction.

[0201] The conveying device preferably includes at least two conveying branches that are at least substantially parallel to each other and oriented parallel to the conveying direction.

[0202] The conveying device is preferably designed such that the return guide channel is guided under the conveying branch line and is arranged close to the temperature control device or the ventilator.

[0203] By arranging two different conveying mechanisms, the conveying device is asymmetrical overall. Preferably, the roller conveyor is positioned closer to the temperature control device or ventilator because it has a lower construction height due to the lack of a chain return section. Therefore, the return guide channel can be guided through the roller conveyor.

[0204] The inlet for drawing out or returning circulating air, i.e., the inlet for returning the guiding channel, is preferably located between the roller conveyor and the chain conveyor, wherein the inlet is preferably located at the height of the temperature control device with reference to the conveying direction.

[0205] Furthermore, chain conveyors have the advantage of having so-called trolleys to facilitate low-friction and low-wear conveying, which absorb the normal force when conveying the workpiece, while the tension is provided via the chain of the conveyor.

[0206] What could be advantageous is that

[0207] a) Between at least one conveying device and at least one side wall of the temperature control chamber, preferably on both sides of the conveying device on the bottom side, and / or

[0208] b) Between every two conveying devices arranged sequentially along the conveying direction, preferably on the bottom side, and / or

[0209] c) In a temperature-controlled chamber or above the workpiece

[0210] One or more additional inlet openings are provided, which preferably include or are configured as nozzles.

[0211] The additional entry opening between the side wall and the conveying device preferably includes a threshold nozzle or bottom nozzle for a workpiece configured as a sill (Schweller) of a motorized vehicle body, or is configured as such a threshold nozzle or bottom nozzle.

[0212] Alternatively, the bottom nozzles can be positioned between the two branches of the conveying equipment. A circulating air supply is achieved here by alternating application to pressure chambers opposite each other.

[0213] In the case of a conveyor with one or both conveyor chains, it may be necessary to provide a gap or recess for the bottom nozzle in the bottom area below one or more conveyor chains.

[0214] Alternatively, it may be necessary to raise the height of the conveyor.

[0215] Additional inlet openings or nozzles in the top or top area of ​​the conditioning chamber preferably guide circulating air from the connecting passage between the pressure chambers into the conditioning chamber.

[0216] Advantageously, the nozzles for introducing temperature-controlled circulating air are positioned in the top area of ​​the temperature-controlled chamber, which directs or guides the circulating air toward the windshield opening and / or rear window opening of the workpiece configured as the body of a motorized vehicle.

[0217] Preferably, the circulating air flows from these nozzles at an angle of approximately 45 degrees relative to the vertical toward the windshield opening and / or the rear window opening.

[0218] It can also be specified that the so-called sandwich top is arranged below the top of the temperature control chamber, which allows for the free placement of additional inlet openings or nozzles above the workpiece to be processed.

[0219] In one embodiment of the invention, at least one additional temperature control unit may be provided upstream of the additional inlet opening.

[0220] The additional temperature control unit upstream of the additional entry opening in the bottom region can accelerate the heating behavior of high-quality workpiece areas, such as the threshold of the body of a motor vehicle being processed, or certain bottom structures.

[0221] Another advantage is that the conditioning chamber has two sidewalls that are at least generally parallel to each other and oriented parallel to the conveying direction, wherein the sidewalls of the conditioning chamber have multiple inlet openings through which circulating air can be introduced from the pressure chamber into the conditioning chamber.

[0222] In one embodiment of the invention, the inlet opening may be specified as a nozzle or configured as a nozzle.

[0223] The shape, size, and spacing between the openings and / or between the edges of the sidewalls are preferably adapted to the workpiece to be conditioned.

[0224] Preferably, the nozzle can be aimed at a predetermined area of ​​the workpiece.

[0225] The nozzle is particularly movable and thus can be individually oriented.

[0226] For example, the nozzle has a spray diameter or flow cross-section of 100 mm and can be tilted up to 15 degrees in the spatial direction relative to the main axis of the nozzle or the axis perpendicular to the corresponding side wall of the temperature control chamber.

[0227] Alternatively, the nozzle can be constructed as an angled nozzle with a fixed angle of, for example, 25 degrees, wherein the angled orientation is particularly referenced to the plane of the corresponding sidewall of the temperature control chamber.

[0228] The nozzles can also be arranged in groups on the corresponding side walls of the temperature regulation chamber.

[0229] For example, four angled nozzles can form a nozzle group or nozzle assembly, which is preferably aligned with a predetermined area of ​​the workpiece to be processed.

[0230] The nozzles in this type of group can have the same angle or different angles.

[0231] By grouping the angled nozzles, jet or flow characteristics approximately the same as those of movable nozzles can be achieved without significantly increasing the length in the axial direction, i.e., perpendicularly from the sidewall toward the temperature control chamber. Therefore, there is no need to expand the corresponding pressure chamber.

[0232] The nozzles on the opposite sidewalls of the beat or zone are preferably arranged such that, for example, in the case of the motorized vehicle body as the workpiece to be processed, no spraying or flow equilibration occurs inside the motorized vehicle body.

[0233] In this context, the cyclic operation mode of the temperature control equipment is advantageous because the various areas of the workpiece, which is constructed as the main body of a motorized vehicle, can be targeted with temperature-controlled circulating air during the temporary downtime or rest time of the workpiece within a time cycle.

[0234] The inlet openings can have the same or different flow cross sections.

[0235] In addition to the entry opening in the side wall of the conditioning chamber, a nozzle assembly for the threshold area of ​​the workpiece, which is constructed as the body of a motorized vehicle, can be arranged, for example, between the side wall of the conveyor and the bottom area of ​​the conditioning chamber, so as to blow the threshold area of ​​the motorized vehicle body with temperature-controlled circulating air.

[0236] In addition, additional bottom nozzles can be arranged between the roller conveyor and the chain conveyor to blow temperature-controlled circulating air into the bottom area and / or the interior area of ​​the motor vehicle body.

[0237] As previously stated, a pretreatment chamber is preferably constructed behind the ventilator, i.e. downstream of the ventilator, which includes the portion into which the ventilator and temperature control unit are pushed.

[0238] The pretreatment chamber preferably divides the associated or surrounding pressure chamber into two sections, which are arranged before and after the pretreatment chamber with reference to the conveying direction.

[0239] The pretreatment chamber serves as a circulating air distribution chamber, through which circulating air is supplied to the temperature control unit and then further guided into the pressure chamber via the temperature control unit.

[0240] Additionally, it can be specified that a bottom-cutting chamber is arranged between the corresponding side walls of the pretreatment chamber and the conditioning chamber.

[0241] The undercut chamber has an additional inlet opening or nozzle, by which circulating air can be applied to the front and / or rear of a workpiece configured as the body of a motorized vehicle, which is then conveyed into a temperature-regulating chamber for temperature regulation. Therefore, the inlet opening of the undercut chamber guides the circulating air, with reference to the longitudinal extension of the workpiece, to the front section of the workpiece in the temperature-regulating module located at the rear along the conveying direction and the rear section of the workpiece in the temperature-regulating module located at the front along the conveying direction.

[0242] The undercut chamber is preferably spatially separated from the pretreatment chamber in the width direction of the temperature control device, and is supplied with or subjected to filtered circulating air from two adjacent pressure chamber sections, for example.

[0243] The inlet or nozzle of the undercut chamber is preferably constructed as a nozzle box that can be accessed and secured from the temperature control chamber via a fastening element, such as a vortex.

[0244] If a bottom-cut chamber is provided, the suction nozzle of the fan retracts and transition channel elements are required to construct the suction chamber.

[0245] In another design of the invention, multiple filter elements may be arranged upstream of the inlet opening to filter the circulating air to be introduced into the temperature-controlled chamber.

[0246] It is also advantageous that at least one pressure chamber can be accessed via at least one pressure chamber door for maintenance and / or regulation work.

[0247] Because the temperature control device of the power module is at least partially arranged in one of the pressure chambers, it is interrupted in sections and therefore cannot be used as a passage. Therefore, one or more pressure chamber doors located at the front of the temperature control device are, for example, insufficient to access all the inlet openings and / or filter elements.

[0248] Therefore, it is advantageous to arrange the pressure chamber door in the side wall of the temperature regulation chamber or in the shell wall of the equipment housing.

[0249] Preferably, each pressure chamber can be accessed via at least one pressure chamber door.

[0250] For the pressure chamber door located inside, i.e. the door in the side wall of the conditioning chamber, the access to the pressure chamber can be designed such that no entry opening is provided in the associated side wall in the area or section of the corresponding pressure chamber door. That is, in this area, the arrangement of nozzles or entry openings in the corresponding side wall is interrupted by a pressure-sealed door that leads to the pressure chamber located behind it when viewed from the perspective of the conditioning chamber.

[0251] However, alternative access methods via the internal pressure chamber door can be designed so that the arrangement of the inlet opening or nozzle in the side wall is not interrupted during equipment operation.

[0252] For this purpose, the nozzle box or nozzle panel is arranged, for example, in a removable manner on the side of the pressure chamber door facing the temperature control chamber.

[0253] The nozzle panel can preferably be detachably fastened to the side wall surrounding the pressure chamber door by means of fasteners, and can be removed to access the covered pressure chamber door.

[0254] The pressure chamber door itself has one or more filter elements, which are either integrated into the pressure chamber door or arranged on the side away from the temperature control chamber, so that they rotate away from their operating position when the pressure chamber door is opened.

[0255] The pressure chamber door located on the outside, i.e. the door in the housing wall of the equipment housing, is preferably pressure-sealed and isolated.

[0256] In cases where the pressure chamber is constructed to be so narrow that it is impassable, it is preferable to provide an opening in the side wall of the conditioning chamber, through which the filter element can first be guided in one orientation from the conditioning chamber so that it can then be detachably fastened in its orientation to the corresponding side wall of the conditioning chamber on the side opposite to the conditioning chamber for operation.

[0257] The filter element is preferably mounted against a corresponding side wall of the temperature-controlled chamber, wherein a seal is preferably provided between the filter element and the support area of ​​the associated side wall, the sealing effect being enhanced by the clamping force generated by the mounting at the side wall and / or by the circulating airflow applied during operation.

[0258] The mounting openings for securing the filter elements are preferably provided in the side wall and are covered by the corresponding filter elements in their operating or filtering posture on the side away from the temperature control chamber, such that the circulating air enters the corresponding openings at least approximately through the filter elements without passing beside the filter elements.

[0259] Preferably, nozzle panels or nozzle boxes are used as components to cover these assembly openings from the direction of the temperature control chamber, wherein these nozzle panels are preferably detachably fastened to the associated side wall of the temperature control chamber by fasteners.

[0260] In order to allow as little or no circulating air as possible to flow past the nozzle panel into the temperature control chamber, the nozzle panel, for example, has a surrounding V-shaped rim (Umkantung) that, when placed in the sidewall, points away from the temperature control chamber.

[0261] In addition, the associated openings in the sidewalls of the temperature control chamber have corresponding surrounding, V-shaped receiving portions into which the V-shaped edging of the nozzle panel can engage.

[0262] Therefore, the circulating air flowing from the pressure chamber toward the nozzle panel is largely trapped in the edge area of ​​the nozzle panel, rather than flowing past it into the temperature control chamber.

[0263] A seal and / or sealing lubricant of corresponding construction may be arranged between the receiving part of the opening and the edge of the nozzle panel, or a sealing lubricant may be applied to at least one of the contact surfaces.

[0264] In the case of a pressure chamber with a reduced width, i.e., perpendicular to the conveying direction, undesirable heat input may occur from the temperature control unit to the corresponding pressure chamber. Therefore, it is advantageous to have the temperature control unit at least partially thermally insulated in the direction of the inlet opening in order to avoid local overheating of the circulating air guided through the pressure chamber.

[0265] Preferably, in the power module, the area between the temperature control unit and the fan on one side and the temperature control chamber on the other side is thermally insulated.

[0266] In particular, the area of ​​the undercut chamber is thermally insulated in such a way that the circulating air from the nozzles that is not introduced into the undercut chamber is overheated due to one or more temperature control units of the power module.

[0267] In the case of a narrow, especially impassable, pressure chamber of the temperature control module, the power module protrudes beyond the temperature control module on both sides in the width direction, that is, transversely to the delivery direction.

[0268] Considering the arrangement of the temperature control device within the power module, the temperature control module is preferably sized and constructed in such a way that a single temperature control module can be transported as a flat package in an open-top container without the need for a conveying device for maritime transport. For this purpose, the temperature control module can be disassembled into two parts, specifically by flipping or rotating the top of the module into one of the two pressure chambers and flipping or rotating the bottom of the module into the other pressure chamber. The width of these two packages is preferably less than or equal to the maximum net width of the open-top container.

[0269] In one embodiment of the invention, an inlet opening or nozzle may be provided in a region of the side wall of the temperature control chamber, where, due to space constraints, a filter element cannot be installed upstream of these inlet openings, for example, in the region of a fan or in the region of a pressure chamber door in the housing wall of the equipment housing. In this case, filtered circulating air is supplied from at least one of adjacent pressure chambers or pressure chamber sections to such an unfiltered inlet opening.

[0270] In one embodiment of the invention, all pressure chambers may be accessible via two pressure chamber doors of each temperature control device for maintenance and / or regulation, the pressure chamber doors being arranged before and after the temperature control device with reference to the conveying direction.

[0271] Therefore, even if the temperature control device is at least partially located in the pressure chamber, all areas of the pressure chamber are accessible.

[0272] Preferably, no filter element is provided in the area of ​​the power module.

[0273] It may also be specified that at least one temperature sensor is arranged in the temperature control equipment, preferably in the temperature control chamber and / or pressure chamber, in order to determine and / or monitor the temperature of the circulating air.

[0274] The object of the present invention is also achieved by a method for heating a workpiece in a temperature control device, particularly for heating the body of a motorized vehicle.

[0275] The method preferably has one or more of the features and / or advantages described in conjunction with the temperature control device. The temperature control device preferably also has one or more of the features and / or advantages described in conjunction with the method.

[0276] The method according to the present invention includes the following steps:

[0277] - The circulating air is conditioned by means of at least one temperature regulating unit, preferably at least three temperature regulating units, wherein the temperature regulating device is arranged at least in sections in the first pressure chamber of the temperature regulating equipment;

[0278] - Temperature-controlled circulating air is introduced into the temperature-controlled chamber of the temperature-controlled equipment via a first pressure chamber and a second pressure chamber. The first pressure chamber is located on one side of the temperature-controlled chamber, while the second pressure chamber is located on the other side of the temperature-controlled chamber and is connected to the first pressure chamber by fluid interaction.

[0279] - Temperature regulation of workpieces being conveyed through the temperature regulation chamber;

[0280] - A ventilator, using a temperature-regulating device, draws recirculated air from the temperature-regulating chamber; this ventilator is arranged at least sectionally within the first pressure chamber; and

[0281] - Circulating air is supplied to at least one temperature control unit, preferably at least three temperature control units.

[0282] Other preferred features and / or advantages of the invention are illustrated in the accompanying drawings and the subject matter described below. Attached Figure Description

[0293] Temperature control equipment as a whole, marked with 100 Figure 1 and Figure 2 The embodiment shown is used for temperature control of a workpiece (not shown).

[0294] Temperature control equipment 100 is particularly used for heating the body of a motorized vehicle (not shown).

[0295] The workpiece is conveyed in the temperature control device 100 along the conveying direction 102.

[0296] Preferably, the workpiece, which is constructed as the main body of a motorized transport vehicle, is conveyed through the temperature control device 100 along the conveying direction 102 in its longitudinal direction.

[0297] The temperature control device 100 includes at least two temperature control modules 104 arranged sequentially along the conveying direction 102 and at least one power module 105 arranged between the two temperature control modules 102 and connected to each other.

[0298] Temperature control module 104 and power module 105 together constitute a continuous temperature control chamber 106. Workpieces can be conveyed into temperature control chamber 106, conveyed through temperature control chamber 106, and conveyed out of temperature control chamber 106 again.

[0299] The temperature control module 104 also has pressure chambers 108 on both sides of the temperature control chamber 106, through which circulating air can be introduced into the temperature control chamber 106.

[0300] Pressure chambers 108 are interconnected by means of a fluid action via connection channel 110 of power module 105 or connection chamber of power module 105.

[0301] The connection channel 110 can be arranged as a bridging channel on one or both temperature control modules 104. However, it is also conceivable that the connection channel 110 is configured as the top of a mezzanine within one of the temperature control modules 105 and / or 104.

[0302] The connecting channel 110 is preferably arranged in the center of the temperature regulating chamber 106 with reference to the conveying direction 102.

[0303] The power module 105 also includes a temperature control device 114, by means of which at least a portion of the circulating air guided through the temperature control chamber 106 can be temperature controlled, i.e., in particular, heated and / or cooled.

[0304] The temperature control device 114 is arranged on one side of the temperature control chamber 106, so the arrangement of the temperature control device 114 is asymmetrical.

[0305] The side integration of the temperature control device 114 in the power module 105, i.e., the at least segmental arrangement of the temperature control device 114 in one of the pressure chambers 108, enables a particularly compact construction of the temperature control device 100.

[0306] Temperature control device 114 is used for circulating and temperature control of the circulating air supplied through temperature control chamber 106.

[0307] Multiple inlet openings 118 are provided in the two side walls 116 of the temperature regulation chamber 106, through which circulating air is introduced into the temperature regulation chamber 106.

[0308] The access opening 118 can have different and / or the same shape and size.

[0309] The shape, size, and spacing between the openings 118 and / or between them and the edges of the sidewalls 116 can be adapted to the workpiece to be conditioned.

[0310] A conveying device 120 is arranged in the bottom area of ​​the conditioning chamber 106, which conveys the workpiece through the conditioning chamber 106.

[0311] Temperature control device 114 includes a fan 122 driven by motor 124 (e.g. Figure 4 (As shown).

[0312] Motor 124 is preferably constructed as electric motor 125.

[0313] The motor 124 is arranged at least in sections outside the two temperature control modules 104.

[0314] The motor 124 of the temperature control device 124 protrudes beyond the temperature control module 104 in the direction of the width 126 of the temperature control module 104 or the temperature control device 100, wherein the width 126 of the temperature control module 104 or the temperature control device 100 is preferably horizontal and perpendicular to the conveying direction 102.

[0315] The extent to which the motor 124 protrudes beyond the width 126 of the temperature control module 104 is preferably less than approximately 25%, preferably 20%, and particularly preferably 10% of the width 126 of the temperature control module 104, so that the temperature control device 100 is configured to be space-saving in the direction of the width 126.

[0316] The temperature control device 114 also includes a first temperature control unit 128 and two second temperature control units 130, wherein the temperature control units 128 and 130 are preferably configured as electric heating units 131.

[0317] The first temperature control unit 128 is arranged above the fan 122, while the second temperature control unit 130 is arranged to the side of the fan 122.

[0318] The two second temperature control units 130 are preferably arranged in a mirror-symmetrical manner with reference to a vertical plane oriented perpendicular to the conveying direction 102 and extending centrally in the temperature control device 114.

[0319] The first temperature control unit 128 provides at least approximately 25%, preferably 35%, and particularly preferably 50% of the heating power of the temperature control device 114, and the two second temperature control units 130 correspondingly provide at least approximately 10%, preferably 15%, and particularly preferably 25% of the heating power of the temperature control device 114, respectively.

[0320] The flow cross-section of the first temperature regulating unit 128 corresponds to at least approximately 25%, preferably 50%, and particularly preferably 100% of the flow cross-section of the two second temperature regulating units 130.

[0321] The connecting channel 110 is preferably about the same width as the first temperature control unit 128 in the conveying direction 102, so that the circulating air regulated by the first temperature control unit 128 can be transferred to the other side of the temperature control chamber 106 without changing the flow cross section.

[0322] exist Figure 3 It shows Figure 1 and Figure 2 A schematic horizontal longitudinal section of the implementation method.

[0323] As can be seen in detail in this longitudinal cross-sectional view, the conveying device 120 is arranged on the bottom side of the temperature control chamber 106. The conveying device includes a chain conveyor 132 and a roller conveyor 134, or it can be configured as a chain conveyor 128 and a roller conveyor 130.

[0324] The roller conveyor mechanism 134 is arranged on the side of the conveying device 120 that is close to or faces the temperature control device 114 or the fan 122. Therefore, the chain conveyor mechanism 132 is arranged on the side of the conveying device 120 that is farther away from the temperature control device 114 or the fan 122.

[0325] Circulating air is drawn out of the temperature control chamber 106 via the return guide channel 136, wherein the return guide channel inlet 137 is centrally located between the temperature control modules 104.

[0326] The return guide channel 136 is preferably arranged on the bottom side and is preferably guided through the area below the roller conveyor mechanism 134.

[0327] The return guide channel 136 includes an outlet section 138 that connects the return guide channel 136 to a pressure chamber 108 in which a temperature control device 114 is integrated.

[0328] The flow cross section of the outlet section 138 of the return guide channel 136 is preferably increased at least approximately to the inlet flow cross section of the fan 122 in the direction of the temperature control device 114, thereby achieving improved blowing of the fan 122.

[0329] In addition, in pressure chamber 108, filter element 140 is arranged upstream of inlet opening 118, which filters circulating air before it is introduced into temperature control chamber 106.

[0330] Each of the temperature control units 128 and 130 includes a plurality of heating elements 142, which are preferably arranged substantially entirely in the corresponding pressure chamber 108.

[0331] A schematic vertical cross-section illustrating an embodiment of the temperature regulating device 100 according to the present invention is shown. Figure 4 It can also be seen that an extraction chamber 144 is arranged upstream of the fan 122, which is preferably configured as a radial fan 143, and the extraction chamber is attached to the outlet section 138 of the return guide channel 136.

[0332] The suction chamber 144 is formed by a transition channel element 145, as the fan 122 retracts in the direction of the width 126. The transition channel element 145 is connected to the suction nozzle 146 of the fan 122.

[0333] Furthermore, as can be seen from the cross-sectional view, the power electronics 147 of the temperature control units 128 and 130 are at least substantially completely arranged outside the temperature control module 104, thereby making it easy to access the power electronics 147 during maintenance work and other processes.

[0334] exist Figure 4 The diagram also shows the circulating air being guided through a ring-shaped structure of the temperature control device 100.

[0335] Circulating air from the pretreatment chamber 148 surrounding the fan 122 is guided past the heating element 142 of the temperature control units 128 and 130. The circulating air is conditioned, preferably heated, as it passes the heating element 142 of the temperature control units 128 and 130.

[0336] Thus, a portion of the circulating air, preferably approximately 50%, is delivered to pressure chamber 108, in which temperature control device 114 is integrated at least in sections, while another portion of the circulating air, preferably approximately 50%, is delivered to pressure chamber 108 via connecting channel 110, which is located on the other side of temperature control chamber 106.

[0337] Circulating air is introduced from pressure chamber 108 through inlet opening 118 arranged in side wall 116 of temperature control chamber 106 and filtered in filter element 140, so as to temperature control the workpiece conveyed through temperature control chamber 106 along conveying direction 102.

[0338] Recirculated air is drawn from the temperature control chamber 106 by the fan 122 via the return guide channel 136; the drawn recirculated air reaches the outlet section 138 of the return guide channel 136 via the return guide channel 136.

[0339] The circulating air is directed from the outlet section 138 into the suction chamber 144, and from there is directly drawn in by the fan 122 and then radially directed back into the pretreatment chamber 148, so as to be re-temperatured by the temperature control units 128, 130 and then directed back into the temperature control chamber 106.

[0340] exist Figure 5 The image schematically illustrates a first embodiment of the heating zone 150 of the temperature control device 100, which is preferably configured for a workpiece constructed as the body of a motorized vehicle, the workpiece having a length of up to 5 m.

[0341] The schematic heating zone 150 includes two cycle stations 152, whereby the main body of the motor vehicle is temporarily positioned or stopped before being conveyed along the conveying direction 102 to the next zone or the next cycle station 152 of the temperature control equipment 100, so as to be temperature controlled by circulating air.

[0342] The cycle station for the main body of a motorized transport vehicle up to 5m in length preferably has an extension of 5.5m in the conveying direction 102, thereby enabling... Figure 5 The heating zone 150 shown has a total longitudinal extension of 11m.

[0343] exist Figure 6 The diagram schematically illustrates a second embodiment of the heating zone 150, which is provided for longer workpieces, particularly for motorized vehicle bodies with a length of up to 6 m.

[0344] In order to avoid changing the power module 105 and the adjacent temperature control module 104 for the longer motor vehicle body, intermediate modules 154 are added at the beginning and end of the heating zone 150 according to the conveying direction 102, so as to achieve a sufficiently long cycle station 152.

[0345] The intermediate module 154 for the heating zone 150 preferably has a longitudinal extension of 1m.

[0346] Therefore, the cycle station 152 has an extension of 6.5m in the conveying direction 102, and the heating zone 150 is thus extended to a total longitudinal extension of 13m.

[0347] exist Figure 7 The first embodiment of the holding area 156 is also schematically shown, which is particularly provided for the main body of a motorized vehicle having a length of up to 5m.

[0348] The holding area 156 preferably includes a power module 105 and four temperature control modules 104.

[0349] Two external temperature control modules 104 provide cycle time stations 152 respectively, and the temperature control module 104 adjacent to the power module 105 provides cycle time stations 152 together with the power module 105.

[0350] Therefore, the two external temperature control modules 104 extend 5.5m in the conveying direction 102, and the two internal temperature control modules 104 together with the power module 105 extend 11m. Figure 7 The holding area 156 shown has a total longitudinal extension of 22m.

[0351] exist Figure 8 The second embodiment of the holding region 156 is schematically shown, which corresponds to... Figure 6 The second embodiment of the heating zone 150 is comparable.

[0352] The second embodiment of the holding area 156 of the temperature control device 100 is particularly provided for the main body of a motor vehicle having a length of up to 6m.

[0353] To extend the cycle station 152, intermediate modules 154 are added at the beginning and end of the holding area 156, respectively, with reference to the conveying direction 102. The intermediate modules 154 for the holding area 156 preferably have an extension of 2m in the conveying direction 102.

[0354] This also results in a cycle station 152 with an extension of 6.5m in the conveying direction 102. Therefore, the second embodiment for the holding area 156 for the main body of the motorized vehicle, which is up to 6m long, has a total extension of 26m in the conveying direction 102.

[0355] From the corresponding Figures 5 to 8 As can be seen in the first and second embodiments of the heating zone 150 or the holding zone 156, the temperature control device 100 can preferably be changed to have two temperature control modules 104 or power modules 105 and two temperature control modules 104 with a length not exceeding 11m, so that these modules can preferably be transported together with a 40' flat rack or a 40' open top container or a 40' high box container.
