The exhaust system 132 further comprises a fan 120 , by means of which air from the temperature control room 106 can be extracted and released to the environment.

A return channel can also be used as an option 138 be provided, by means of which a connection between the exhaust air duct 134 the exhaust system 132 and the supply air duct 116 the supply air system 114 can be produced.

In particular, via the return channel 138 Exhaust air can be mixed with the supply air. For this purpose, in particular a flap and / or a valve device together with a suitable control and / or regulation system can be provided in order to control and / or regulate the admixture of a predetermined exhaust air flow to the supply air.

How in particular 1 can be seen, is the temperature control system 100 in several temperature control system sections 140 divisible, each temperature control section 140 for example forms a temperature control system module.

The temperature control system sections 140 are in particular along the conveying direction 110 arranged consecutively.

A temperature control system section 140 is preferably the supply air system 114 assigned.

Another temperature control system section 140 is preferably the exhaust system 132 assigned.

The supply air system 114 and the exhaust system 132 are preferably at opposite ends of the temperature control system 100 arranged temperature control system sections 140 arranged.

The air circulation system 130 is in particular one or more temperature control system sections 140 assigned or arranged thereon which between the supply air system 114 and the exhaust system 132 are arranged.

In the case of the 1 until 7th illustrated first embodiment of the temperature control system 100 are the components of the supply air system 114 , the air circulation system 130 and the exhaust system 132 relatively far away from each other, so that an installation space along the conveying direction 110 can be used optimally.

The fans 120 the supply air system 114 , the air circulation system 130 and / or the exhaust system 132 are preferably aligned in such a way that their axes of rotation 142 essentially parallel to the conveying direction 110 get lost.

An installation space and / or maintenance space for the fans 120 thus extends essentially parallel to the conveying direction 110 from the respective fan 120 away, creating a side for maintenance of the temperature control system 100 required space can be minimized.

Like the one in particular 1 and 7th can also be found in the supply air system 114 starting from one end of the temperature control system 100 along the conveying direction 110 preferably the following components are arranged one after the other: first is the fan 120 provided on which along the conveying direction 110 one or more heat exchangers 128 and / or one or more filter stages 126 consequences. Along the conveying direction 110 this is followed by a support area 144 to support the, for example, as a ventilation tower 114 trained supply air duct 116 .

Such a design of the air supply system 114 can the temperature control system 100 are preferably made particularly short, since along the conveying direction 110 via the temperature control room 106 no additional components are required. Rather, the air is drawn in at one end of the temperature control room 106 spaced-apart intermediate area, with a supply of air to the temperature control room 106 at the immediate end of the temperature control room 106 can be done.

One in the 8th until 15th illustrated second embodiment of a temperature control system 100 differs from that in the 1 until 7th illustrated first embodiment essentially in that the temperature control system 100 is very compact and especially in the conveying direction 110 has a shorter length.

The resulting reduced installation space along the conveying direction 110 is compensated in this embodiment in particular by the fact that the axes of rotation 142 the fans 120 (see in particular 11 ) not parallel to the conveying direction 110 , but are oriented perpendicular to this.

The individual components of the supply air system 114 , the air circulation system 130 and the exhaust system 132 can hereby be arranged particularly close to one another and / or one after the other.

Such a shortened configuration of the temperature control system 100 can especially in the case of a transverse conveyance of the workpieces 102 be provided.

In such a transverse conveyance, there is a longitudinal axis of the workpieces 102 essentially horizontal and perpendicular to the conveying direction 110 aligned while the workpieces 102 along the conveying direction 110 through the temperature control room 106 be conveyed through. Like the one in particular 12th and 13th can be found in the air circulation system 130 as is the case with the exhaust air system 132 the temperature control system 100 according to the second embodiment, one or more suction openings 145 in a floor area 146 the temperature control system 100 intended. The air is supplied via one-sided pressure chambers 124 (see in particular 10 ).

As 12th can also be seen in the second embodiment of the temperature control system 100 five temperature control system sections 140 the temperature control system 100 provided, each temperature control section 140 a holding position of the workpieces 102 in a cycle conveyor operation of the conveyor device 108 is equivalent to.

At the first two stop positions (temperature control system sections 140 ), ie at the holding positions I and II (cycle 1 and cycle 2) the air is sucked out of the temperature control room 106 by means of the exhaust system 132 . Here is an underbody duct 147 in the temperature control system section forming the holding position II 140 intended. The underbody duct 147 runs below the temperature control room 106 and connects the suction port 145 the stop position II with the fan 120 the exhaust system 132 .

A suction port 145 the holding position I is by means of a connection area 149 with that of the suction opening 145 the end of the underbody channel facing the holding position II 147 the holding position II connected, so that over the underbody duct 147 the holding position II both the air from the holding position I and the air from the holding position II can be sucked in.

At the three other temperature control system sections 140 , ie at the holding positions III, IV and V (cycle 3, cycle 4, cycle 5), suction is carried out by means of the air circulation system 130 . In this case, each of the holding positions III, IV, V preferably has a separate underbody channel 147 for connecting the suction opening 145 of each stop position III, IV, V with the fan 120 the air circulation system 130 on.

The one via the supply air system 114 Air supplied in the last cycle (stop position V, cycle 5) flows through the temperature control room 106 thus against the conveying direction 110 , since these are initially in the temperature control system sections forming the holding positions III, IV, V 140 by means of the air circulation system 130 circulated and finally in the temperature control system sections forming the holding positions I and II 140 by means of the exhaust system 132 is discharged.

How finally 15th it can be seen, it can be advantageous if one is used as a ventilation tower 118 trained supply air duct 116 and / or as a ventilation tower 136 trained exhaust duct 134 an access opening 148 , for example a flap. This allows a return channel in particular 138 connected or a maintenance access established.

As through the access opening 148 a structural weakening of the ventilation tower 118 , 136 this is preferably provided with a reinforcement structure 150 Mistake.

The reinforcement structure 150 is in particular a rectangular reinforcing ring or stiffening ring which passes through the access opening 148 through into the access opening 148 having section 152 of the ventilation tower 118 , 136 is retractable.

By means of the reinforcement structure 150 can thus, in particular, provide additional external stiffening or reinforcement or other support for the ventilation tower 118 , 136 can be avoided, whereby the entire structure of the temperature control system 100 can be simplified.

Such a reinforcement of the ventilation tower 118 , 136 can also be used in other configurations of the temperature control system 100 , for example according to the in 1 until 7th illustrated first embodiment may be provided.

Incidentally, it is correct in the 8th until 15th illustrated second embodiment of the temperature control system 100 in terms of structure and function with the 1 until 7th first embodiment shown, so that reference is made to the preceding description thereof.

One in the 16 and 17th illustrated third embodiment of a temperature control system 100 differs from that in the 1 until 7th illustrated first embodiment essentially in that the distribution channels 122 not above the housing 112 the temperature control system 100 are arranged.

Rather, the distribution channels are 122 in the 16 and 17th illustrated third embodiment in the housing 112 integrated.

The case 112 includes one or more exterior walls 154 , which in particular with an isolation area 156 are provided or form one. This can result in a large temperature difference between the interior of the housing 112 and its surroundings can be maintained with as little energy loss as possible.

Preferably both surround the outer wall 154 as well as the isolation areas 156 the temperature control room 106 in cross section completely or at least in sections, in particular at least two-sided or at least three-sided.

The function of the distribution channels 122 is used in the 16 and 17th illustrated third embodiment of the temperature control system 100 through a connecting room 158 achieved.

The connecting room 158 particularly connects the two pressure chambers 124 on both sides of the temperature control room 106 together.

The connecting room 158 preferably extends over an entire width of the temperature control space 106 away above the temperature control room 106 , especially in a vertical projection of the temperature control room 106 to the outside wall 154 and / or the isolation area 156 .

A partition 160 separates the connecting room 158 from the temperature control room 106 .

This partition 160 is designed in particular as an uninsulated sheet metal or includes such a sheet.

The partition 160 includes in particular a ceiling partition 162 , which the temperature control room 106 limited upwards and this from the connecting space 158 separates.

In the ceiling partition 162 can optionally have one or more inlet openings 164 for supplying air to the temperature control room 106 be provided.

The connecting room 158 preferably extends over a greater length along the conveying direction 110 as a feed opening 166 to the Supply of air from the air circulation system 130 in the interior of the housing 112 .

It can be advantageous if - as in 17th shown - the feed opening 166 to a feed channel 167 which connects the feed opening 166 with the fan 120 connects and moves towards the feed opening 166 and / or expanded upwards against the direction of gravity. Due to the widening design of the feed channel 167 can preferably achieve a more even distribution of the air to the pressure spaces 124 respectively.

With a view to an optimal distribution of the air supplied to both pressure chambers 124 are preferably one or more guide elements 168 intended. For example, one or more guide elements 168 in the connecting room 158 be arranged to the in the connecting space 158 inflowing air flow along the conveying direction 110 as well as equally on both pressure spaces 124 to distribute. In this way, a uniform flow on both sides of the workpieces can preferably be achieved 102 in the temperature control room 106 be achieved.

As 16 It can also be seen that includes the temperature control system 100 in addition to that of the air circulation system 130 the filter level to be assigned 126 preferably at least one further filter stage 126 .

In particular, that of the air circulation system 130 assigned filter level 126 a coarse filter stage 170 .

The further filter stage 126 is in particular a fine filter stage 172 . The further filter stage is preferred 126 in the interior of the housing 112 arranged, for example in the partition 160 integrated.

The partition 160 includes in particular a side partition for this purpose 174 , which the temperature control room 106 is facing, and one of the respective pressure chamber 124 associated filter partition 176 .

In the filter partition 176 are one or more receptacles for one or more filter elements, in particular filter mats 178 , arranged and / or designed, which the filter stage 126 form.

Between the filter partition 176 and the side partition 174 is preferably a distribution room 180 formed to be passed through the filter stage 126 air flowing evenly onto one or more inlet openings 164 in the side partition 174 to be able to distribute and thus a uniform supply of air to the temperature control room 106 to enable.

In that the connecting space 158 the two pressure rooms 124 over a great length along the conveying direction 110 connects with each other and thus enables a large duct cross-section even at low heights, the entire temperature control system can 100 be compact. In addition, by using the connection space 158 preferably thermal insulation can be optimized.

16 Finally, it can also be seen that the extraction by means of the fan 120 in the floor area 146 takes place to air from the temperature control room 106 and finally one or more heat exchangers 128 and / or one or more filter stages 126 to feed.

Especially when using the temperature control system 100 for heating workpieces 102 it can be provided that the air by means of one or more heat exchangers 128 is strongly heated. A uniform flow to the respective heat exchanger 128 is preferably by means of one or more guide elements 168 , especially baffles 182 , guaranteed.

In particular, different levels of guide elements can be used here 168 be provided, for example from the floor area 146 inflowing air first in a vertical direction and then or at the same time evenly in the horizontal direction on the heat exchanger 128 to be distributed (see in particular 17th ).

This allows for even heating of the, for example, by means of a circulating air system 130 recirculated air can be achieved.

Incidentally, it is correct in the 16 and 17th illustrated third embodiment of the temperature control system 100 in terms of structure and function with the 1 until 7th first embodiment shown, so that reference is made to the preceding description thereof.

In a further embodiment of a temperature control system, not shown 100 it can be provided that the connecting space 158 Is formed in several parts and in particular an air flow in both directions perpendicular to the conveying direction 110 and horizontally.

This can be advantageous, in particular, if one-sided recirculation of air is undesirable and thus also a return of air through the connecting space 158 is desired.

In 18th is a fourth embodiment of a temperature control system 100 shown, which is essentially the one in the 16 and 17th corresponds to the third embodiment shown, but two temperature control rooms running parallel to one another 106 includes.

In 18th In addition, it cannot be seen that on the opposite outer walls 154 of the two temperature control rooms 106 several air circulation systems each 130 are arranged, which in particular for heating the in the temperature control room 106 serve circulated air.

By using connecting spaces 158 according to the 16 and 17th The third embodiment shown can have such a double arrangement of temperature control rooms 106 be made possible in a particularly compact space, in particular without the requirement that between the temperature control rooms 106 further components of a supply air system 114 , a circulating air system 130 and / or an exhaust system 132 must be mounted.

Incidentally, the in 18th The fourth embodiment shown in terms of structure and function with that in the 16 and 17th illustrated third embodiment, so that reference is made to the preceding description thereof.
