Definitions
- the invention relates to a radiator arrangement for a heater according to the preamble of patent claim 1.
- the associated radiator is usually designed with ribs that extend away from the PTC heating element.
- a known radiator has ribs that extend approximately radially away from one side of the radiator, while the ribs of the other side are oriented approximately parallel to each other.
- EP 1 847 786 A1 discloses a heater having a heat exchanger body or radiator in the main central portion of which PTC elements are accommodated.
- the radiator has ribs which start from the main section and extend on both sides and parallel to one another.
- radiators The heat decoupling of such radiators essentially depends on their surface area and the surface texture, with both parameters be determined with the production of the radiator. Accordingly, the disadvantage of the radiators of the prior art is that their heat extraction is unchangeable, so that a variety of heater outputs from one manufacturer is always accompanied by different radiators.
- the invention is based on the object of creating a radiator and a heater whose heat output can be changed so that it can be used for different power ranges. It should be possible to establish an intimate connection between the inner (middle) contact surfaces and those of the other radiator.
- the claimed radiator arrangement has at least one radiator, which can also be referred to as a heat distribution element or convection body, and is designed to be brought into thermally conductive connection with a PTC heating element.
- An electric heater can thus be formed.
- the radiator has a first group of contact surfaces, to which another, essentially structurally identical radiator can be placed and, for example, can be brought into a thermally conductive connection by gluing or clamping or screwing or welding or soldering or flanging. According to the invention, this results in a modular radiator arrangement consisting of identical parts with heat extraction that can be selected at least in two stages.
- a suitably equipped heater can have a heat output of approx. 170 watts at -20°C.
- contact surfaces of one and the same group in their entirety have an outward curvature when the radiator is in a relaxed state, so that, viewed in cross section, these contact surfaces have an outward arch shape.
- a contact plane can have the outward curvature, so that viewed in cross section, this contact plane has an outward arc shape. A crowning is thus created, via which an intimate connection between the inner (middle) contact surfaces and those of the further radiator can be produced.
- the contact surfaces of the first group are preferably arranged in a first contact plane or can be brought into this contact plane by being pressed together with the further radiator. Then more than two contact surfaces can be brought into thermally conductive connection at the same time.
- the radiator is an extruded profile, preferably made of aluminum or an aluminum alloy.
- the aluminum is preferably anodized and/or painted. This results in a leveled temperature distribution with an improved emission factor and further increased heat extraction.
- the radiator has a second group of contact surfaces, to which another essentially identical radiator can also be placed and which can be brought into a thermally conductive connection, e.g. by gluing or clamping or screwing or welding or soldering or flanging.
- a thermally conductive connection e.g. by gluing or clamping or screwing or welding or soldering or flanging.
- the contact surfaces of the second group are arranged in a second contact level or can be brought into this second contact level by pressing together with the further radiator, more than two contact surfaces of the second group can also be brought into thermally conductive connection at the same time. It is particularly preferred if the two contact levels are symmetrical to one another.
- contact surfaces are spaced apart from one another, so that free spaces remain between the contact surfaces, medium heated during operation can be exchanged between the contact surfaces through the free spaces when on the contact surfaces no other radiator is present.
- the contact surfaces of a group and the spaces between them together form a wide side of the radiator.
- the contact surfaces of the group extend over at least 50% of this broad side, while the free spaces correspondingly extend over at most 50% of the same broad side.
- the abutment surfaces may occupy, for example, 60 to 80% of the width, while the clearances occupy, for example, 20 to 40% of the same width.
- a free space can be developed as a groove, via which a further component can be attached to the radiator.
- the additional component can be the additional radiator or a fastening clip.
- a cross section of the radiator can have an approximately rectangular outer frame.
- the curvature or arc shape according to the invention is produced by a pressing process, which preferably also clamps the PTC heating element in the radiator.
- the curvature or arched shape is produced during extrusion of the radiator.
- the contact surfaces are arranged on respective flat, strip-shaped contact elements. This results in an elongate radiator that can advantageously be produced in the extrusion process.
- the radiator preferably has the shape of a cuboid.
- each of the four long and mutually parallel edges of the parallelepiped is formed by an outer edge of an outer contact element.
- the two outer contact elements of each group or each broad side can be used for this purpose.
- the contact elements can be fastened to a main section via a respective web, in which the PTC heating element can be inserted—preferably clamped—to conduct heat.
- the webs are preferably arranged perpendicular to the respective contact element. This results in a T or L shape of the contact element with the respective web.
- the strip-shaped contact elements and/or the strip-shaped contact surfaces preferably have a width that corresponds to a multiple, for example at least four times, the material thickness of the associated web. Chimneys are thus formed between the main section, the webs and the abutment elements.
- the PTC heating element is preferably constrained within and surrounded by the main portion. in the case of the extruded profile, one of the two openings of the main section is intended for a power supply, while the other opening is completely closed with a seal.
- a first groove is preferably provided in a first narrow outer side of the radiator, via which a further component such as a contact protection or a fastening clip (according to DIN) for the radiator or the heater formed with it can be fastened. It can be attached using screws that are screwed into the groove.
- a further component such as a contact protection or a fastening clip (according to DIN) for the radiator or the heater formed with it can be fastened. It can be attached using screws that are screwed into the groove.
- An anti-twist device or a thermal insulating part is preferably provided between the radiator and the further component.
- a combined intermediate piece that fulfills both tasks is particularly preferred.
- the intermediate piece is then preferably made of thermally insulating material, preferably plastic. In this way, for example, the fastening clip according to DIN can be protected against twisting on the one hand and against excessive temperatures (in particular temperatures above 95°C) on the other.
- the groove has an expanded groove base, over which a screw channel is formed, a screw can also be screwed in there along the groove—in the case of an extruded profile along its pressing direction.
- a second groove can be provided in a second narrow outer side of the radiator, which is mirror-symmetrical to the first narrow outer side. This can also be used to attach one of the two components mentioned above, i.e. a fastening clip or a contact protection on the radiator. If the two grooves each have an enlarged groove bottom, via which a screw channel is formed, a terminal block or a connection housing for the PTC heating element can be securely fastened to an end face of the radiator using two screws.
- the heater according to the invention has at least two radiators as described above, which are in thermally conductive connection with their respective group of contact surfaces. Only one of the radiators is in direct heat-conducting connection with a PTC heating element. The other radiator is in indirect thermally conductive connection with the PTC heating element. Approx. 180 - 350 watts can be achieved without a fan and > 500 watts with a fan at -20°C. Preferably, the PTC heating element is clamped into the main section of the radiator concerned.
- a central radiator with the contact surfaces of each of its two groups is in thermally conductive connection with a respective outer radiator.
- the central radiator is in direct thermally conductive connection with a PTC heating element.
- the PTC heating element is preferably clamped into the main section of the central radiator in question.
- only the two outer radiators are in direct thermally conductive connection with a respective PTC heating element.
- the two PTC heating elements are preferably clamped in the respective main section of the two outer radiators concerned. Without a fan, approx. 400 watts and with a fan approx. 530 watts can be achieved at -20°C.
- a particular advantage of the radiator arrangement according to the invention is that more than three radiators can also be put together in a heat-conducting manner.
- the number of PTC heating elements is variable.
- a heater with radiators is particularly preferred, the outer contact elements of which are gripped around or behind by means of clamps and are thus tensioned against one another.
- the heater can also be used as a tube heater, adapters being used in the areas between the radiators and an inner wall of the tube, for example in the shape of a segment of a circle.
- Flow can preferably flow through the tubular heater in the direction of its extrusion and thus along its contact elements and its webs.
- the heat output can be significantly increased since the convection flow is increased.
- the heater can also be used for a control cabinet.
- figure 1 shows a heater according to the invention according to a first embodiment in a longitudinal section.
- He has a radiator 1, which is designed as an aluminum extruded profile.
- a tubular, flat main section 2 is provided in a middle area of the radiator 1, which is closed at the front side with a seal 4 made of silicone.
- One of the two seals 4 is guided through insulated connection strands 6 which are provided for the electrical supply of a PTC heating element 8 clamped in the main section 2 .
- an insulating sleeve 10 made of Kapton is provided for the PTC heating element 8 .
- figure 2 shows the heater off figure 1 in a cross section.
- the radiator 1 has an approximately rectangular outer frame, resulting in a first wide side 12 and a second wide side 14 and two narrow sides 16 of the radiator 1 .
- the two wide sides 12, 14 have in the in figure 2 shown relaxed state of the radiator 1 each have a slight outward curvature.
- Five contact elements 18 of a first group are arranged on the main section 2 in the region of the first broad side 12, on the respective outside of which a respective contact surface 20 of the first group is formed.
- four contact elements 22 of a second group are arranged in the area of the second broad side 14, on the respective outside of which a corresponding contact surface 24 of the second group is formed.
- a fifth contact element 22a of the second group which is interrupted by a further groove 28a is arranged centrally in the second broad side 14 and on which a contact surface 24a of the second group which is interrupted by the further groove 28a is formed.
- All contact elements 18, 22, 22a are elongated and strip-like and extend perpendicular to the plane of the figure 2 . Furthermore, all contact elements 18 , 22 are connected to the main section 2 via a respective web 26 . Thus, chimneys are formed inside the radiator 1 between the webs 26 and the contact elements 18, 22, the cross section of which is enlarged compared to the star-shaped ribs of the prior art, so that the flow of a medium to be heated is improved and heat accumulation is avoided.
- the radiator 1 is mirror-symmetrical to a center plane 32 .
- a groove 28 is provided on each of the two narrow sides 16 of the radiator 1 , the respective bottom of the groove being designed as a screw channel 30 .
- FIG. 12 shows a fastening clip 34 fastened to the first narrow side 16.
- the fastening clip 34 is fastened via a screw 36 which is screwed into the groove 28 and which extends perpendicularly to the bottom of the groove.
- longitudinal structures are formed on the flanks of the groove 28, which are used for the firm engagement of a screw 36 screwed into the groove 28.
- FIG 3 shows a perspective view of a second embodiment of a heater according to the invention.
- the radiator 1 with the fastening clip 34 and the screw 36 corresponds to that of the first exemplary embodiment according to FIG Figures 1 and 2 .
- Only the power supply of the heater is changed. More precisely, on one of the front sides of the radiator 1 there is a clamping block 38 fastened. Two screws 40 are used for this, which are screwed into the two screw channels 30, which extend along the radiator 1, and which (according to figure 2 ) are formed at the bottom of the grooves 28. Electrical contacting can be easily implemented via the terminal block 38 by means of a supply line (not shown).
- figure 4 shows a perspective view of a development of the second embodiment of the heater according to the invention with a radiator 1 according to figure 3 .
- the radiator 1 is covered on three sides, namely on the two wide sides 12, 14 and on the narrow side 16 opposite the fastening clip 34, with a protection against accidental contact 42.
- the contact protection has a multiplicity of ventilation slots 44 running transversely to the radiator 1.
- the contact protection 42 also has a support section 46 which is fastened to the narrow side 16 of the radiator 1 by two screws 48. For this purpose, the two screws 48 are screwed into the groove 28 there.
- FIG figure 5 shows a heater according to a third embodiment in an exploded drawing or in a not yet assembled state. It contains the heater of the first embodiment according to FIG figure 2 with the radiator 1 and, in addition, another structurally identical radiator 50, in which no PTC heating element is used.
- the two radiators 1, 50 are brought into contact with each other with their respective first wide sides 12.
- the five contact surfaces 20 of the first group of the first radiator 1 are clamped against one another in a heat-conducting manner with the five contact surfaces 20 of the first group of the further radiator 50 .
- Clamps 52 are pushed over the outer contact elements 18 on each side for bracing and securing.
- the radiator 1 which is provided with the PTC heating element 8, a camber, so a curvature of the contact surfaces 20 of the first group.
- This crowning has been produced either when the radiator 1 is pressed with the PTC heating element 8 or when the radiator 1, which is designed as an aluminum profile, is extruded.
- the further radiator 50 has no camber, so that the contact elements 18 of the first group are arranged in one plane and are aligned parallel to the contact elements 22 of the second group of the further radiator 50 .
- the interaction of the curved first group of the radiator 1 with the flat first group of the other radiator 50 results when the outer contact elements 18 are pressed together via the clamps 52 in any case, e.g. B. even with larger manufacturing tolerances, an intimate connection and the three inner contact surfaces of the first groups.
- figure 6 shows in a cross section an already assembled fourth embodiment of the heater according to the invention. It has a radiator system consisting of three essentially identical radiators 1, 50, with the heat-conducting connection of the central radiator 1 to the (in figure 6 lower) additional radiator 50 of those from figure 5 is equivalent to. the inside figure 6
- the upper further radiator 50 is additionally clamped to the middle radiator 1, more precisely to the contact surfaces 24, 24a of its second group.
- a special feature here is that the contact surface 24a of the second group of the middle radiator 1 which is interrupted by the further groove 28a comes into contact with the middle contact surface 20 of the first group of the upper further radiator 50 .
- the contact surfaces 24, 24a of the second group of the radiator 1 are also curved.
- figure 7 shows a perspective view of the fourth embodiment according to FIG figure 6 of the heater according to the invention with the radiator system composed of three radiators 1, 50. It can be seen that for each connection between two radiators 1, 50, two brackets 52 are provided on each side. The clamping block 38 and the fastening clip 34 are screwed onto the middle radiator 1 (cf. figure 3 ).
- the heater is in accordance with this figure 3 by attaching two further radiators 50 modularly expanded in such a way that its surface is increased many times over, and that the (in figure 7 not shown) only central PTC heating element can absorb a comparatively large amount of power and convert it into heat. This applies in particular if a fan (not shown) is added is provided, which promotes an air flow along the strip-shaped contact elements 18, 22, 22a and the corresponding webs 26.
- FIG. 12 shows the heater according to the second embodiment figure 3 in a perspective view, in particular of its second wide side 14.
- the further groove 28a of the second wide side 14 and also the groove 28 of the first narrow side 16 are visible.
- the two grooves 28, 28a offer two fastening options for the fastening clip 34.
- an intermediate piece 54 can be seen in each case. It is arranged between the fastening clip 34 and the radiator 1 and is made of a plastic with good thermal insulation properties, e.g. PPS. The intermediate piece thus serves as thermal insulation of the fastening clip 34 from the hot radiator 1.
- the intermediate piece 54 serves as an anti-rotation device for the fastening clip 34 in relation to the radiator 1.
- the intermediate piece 54 has two shoulders 56, between which the fastening clip 34 is accommodated or clamped in a manner secured against torsion is.
- Figures 9 and 10 show the fastening clip 34 and the intermediate piece 54 figure 8 each in a perspective view.
- the intermediate piece 54 has on its side facing the radiator 1 two cams 58 which together with (the thread) of the screw 36 form a row and which together dip into the groove 28, 28a.
- the two cams 58 thus serve to prevent the intermediate piece 54 from rotating relative to the radiator 1.
- figure 11 shows a section of the heater or radiator 1 figure 8 in a sectional representation of the fastening clip 34 and the intermediate piece 54, which are arranged on the narrow side 16.
- the screw 36 and the two cams 58 have approximately the same diameter, which corresponds to a width of the groove 28 .
- the visible flank of the groove 28 has the longitudinal structure 60.
- the first and the second groove 28, which are each arranged on a narrow side 16 of the radiator 1, and the further groove 28a, which is arranged on the second wide side 14 of the radiator 1 have such a longitudinal structure 60 on both of their flanks. This provides a firm hold for the screws 36, 48, which are screwed in perpendicularly to the bottom of the groove.
