Sannnnelrohr for a heat exchanger device, a

The invention relates to a collecting pipe for a heat exchanger device, according to the preamble of independent claim 1, a heat exchanger device and a method for emptying a heat exchanger device

Heat exchanger device according to the preamble of independent claim 1 1 and a method for emptying a

Heat exchanger device according to the preamble of independent claim 14.

Heat exchange devices can be found in a variety of technical applications, such as in refrigeration systems and devices for

Refrigerators or household refrigerators, in heaters and air conditioning systems for buildings or transport such as cars, buses, ships and aircraft, or as coolers in power plants, internal combustion engines,

Computers, or other heat generating devices. In practical use, the heat exchanger device is often connected to a circuit containing a fluid, ie a heat transfer medium, for example, a coolant, the heat exchanger devices heat directly, ie without phase change from the liquid or gaseous fluid record or deliver to the same, or as a capacitor or evaporator for the fluid can be effective. A widespread design is the laminated one

The heat exchange. In the simplest case, a laminated heat exchanger device consists of a tube for the passage of a fluid and of a plurality of fins which are connected to the tube and in operation communicate with a second medium. This design is particularly useful when the second medium is gaseous and, for example, consists of ambient air, since this has a comparatively low heat transfer coefficient, which can be compensated by a correspondingly large surface of the slats.

Of course, the laminated heat exchanger device may also contain a plurality of tubes for more than one fluid, or the tubes may be connected in parallel and / or in series as needed.

The efficiency is essentially determined by the temperature difference between the fins on the one hand and the or the pipes on the other hand. The temperature difference is the smaller, i. the more effective the heat transfer, the greater the conductivity and the thickness of the fins, and the smaller the mutual distance of the tubes. In terms of efficiency, it is thus advantageous if many tubes are used. However, many tubes also mean higher material and processing costs, so higher efficiency is usually associated with higher costs.

The well-known laminated heat exchanger device, like all types of heat exchanger devices, serves to transfer heat between two media, e.g. for transferring a fluid to air or vice versa, as is known, for example, from a classic household refrigerator, in which heat is released to the ambient air via the heat exchanger device for generating a cooling capacity in the interior of the refrigerator. The second medium outside the

Heat exchange device, such as water, oil or often simply the ambient air, for example, absorbs the heat or is transferred from the heat to the heat exchanger device is either cooled or heated accordingly. In any case, the second medium, eg the air, has a significantly lower heat transfer coefficient than the fluid, ie the heat transfer medium, for example the coolant circulating in the heat exchanger device. This is strong

different heat transfer surfaces for the two media

balanced: The medium with the high heat transfer coefficient flows in the tube, which has on the outside by thin sheets (ribs, fins) a greatly enlarged surface, at which the

Heat transfer e.g. takes place with the air. The production of these so-called laminated

Heat exchanger device is based on a long-known standardized process: The slats are punched with a press and a special tool and put into packages to each other. Then the tubes are inserted and either mechanically or hydraulically expanded so that a very good contact and thus a good

Heat transfer between pipe and lamella is created. The individual tubes are then connected by arches and manifold and manifold, often soldered together.

The efficiency is essentially determined by the fact that the heat that is transferred between the fin surface and the air, must be transmitted through heat conduction through the fins to the pipe.

For the highest possible efficiency, the pipe spacing should be as small as possible, but this leads to the problem that you need many pipes.

However, many pipes also entail high costs because the pipes (usually made of copper) are considerably more expensive than the thin fins.

In addition, a variety of pipes, especially with many

Windings and many bends, in some applications, for example as coolers in power plants, cause the heat exchanger device idle is not completely emptied, but this is an essential requirement for an application in these areas.

It is therefore an object of the present invention to propose a manifold, in particular for a heat exchanger device which has a functional subdivision and / or is simpler and / or less expensive to produce and / or application-optimized.

This task is performed by a manifold for a

A heat exchanger device having the features of claim 1, a heat exchanger device having the features of claim 1 1 and a method for emptying a heat exchanger device with the

Characteristics of claim 14 solved.

According to the invention, a manifold for a

Heat exchanger device proposed, wherein the collecting tube comprises an outflow opening, an inflow opening and a plurality of deflection openings and in a axial longitudinal direction of the collecting tube a Sammelrohrachse is formed. The collecting tube comprises a separating element, wherein the separating element is designed and arranged in the collecting tube such that the separating element moves the collecting tube into an outflow region, in which the

Outflow opening is arranged in an inflow region in which the

Inflow opening is arranged and divided into a first deflection region in which the deflection openings are arranged. The separating element is arranged in such a way to Sammelrohrachse that the separating element forms an angle a with the Sammelrohrachse.

The manifold may, for example, a tubular hollow body but preferably not necessarily with a circular,

be elliptical or polygonal base. Also, that can

Collective tube may be designed as a mainly hollow cylindrical tube that is open at a first and second axial end. In an axial In the longitudinal direction of the collecting tube, the Sannnnelrohrachse may be formed, preferably by the center of gravity of the two bases of the

Collection tube.

The collecting tube comprises the discharge opening, the inflow opening and a plurality of deflection openings. The outflow or inflow or deflection opening, for example, be a hole or a hole in a lateral surface of the manifold, which may be uniform, so cylindrical, elliptical or polygonal. An inner cross section of the inner

The boundary surface of the outflow or inflow or deflection opening may be uniform, for example rectangular, or non-uniform, that is

be formed convex or concave, for example. A plurality of tubes, which may be arranged at the outflow or inflow or deflection opening, may for example be arranged radially centrally to the collecting tube axis, but preferably not perpendicularly to the outer circumferential surface, that is not to be arranged radially centrally to the collecting tube axis. Different outflow or inflow or deflection opening may have the same inlet or outlet cross-section or diameter, but these preferably have a different inlet or outlet

Outlet cross-section or diameter. Advantageously, such a fluid can flow out of the pipes better.

The outflow or inflow or deflection opening may be arranged such that openings of the same category in a first plane

are arranged, for example, with the same distance between the openings. The first plane can thereby enclose an angle f of 0 to 50 degrees with the collecting tube axis, preferably an angle f of 0 to 30 degrees, particularly preferably 0 degrees, ie be arranged parallel to the collecting tube axis. Openings of different categories can

next to each other, preferably with the same distance between the

Openings, to be arranged on a second level. The second level may include an angle g of 40 to 90 degrees with the header axis, preferably an angle of 70 to 90 degrees, more preferably an angle of 90 degrees, so be arranged perpendicular to the collecting tube axis. For example, a plurality of first planes may be arranged parallel to one another and form a first plane group and / or a plurality of second planes may be arranged parallel to one another and form a second layer group. The outflow or inflow or deflection can also be arranged offset from one another as desired.

The separating element may be a film-like material, for example a sheet metal, wherein the material may be, for example, a metal or a metallic alloy, a stainless steel or a plastic. The film-like material advantageously consists of a pressure-stable material, for example a metallic alloy. The thickness of the sheet-like material may, for example, be in a range between 2 and 10 mm.

The separating element may comprise a separating and a deflecting section. The separating section may for example have a rectangular shape and be formed as a flat sheet. The deflection section may have an open polygonal, that is to say, for example, a triangular or quadrangular or semicircular inner cross section and may be designed, for example, as a U-shaped metal sheet or as a channel. The separating element, that is to say the deflecting section and the separating section, can have a Y-shaped inner cross section, wherein the deflecting section can be arranged symmetrically or asymmetrically with respect to the separating section. Likewise, the separating and deflecting section can be made in one piece or in several parts. But it can also be carried out in one piece or in several parts, the separating element. The entire separation element can also be rectangular, in parallel to

Sammelrohrachse be executed one or multiple folded sheet metal. The separating element can have a leakage opening, in particular at the edges of the separating element, for example round or polygonal gaps, indentations or tubular connecting elements, through which, for example, a pressure compensation takes place, ie a fluid can flow. The separating element can be arranged in the collecting tube and can be displaced, for example, in the axial direction and arranged rotationally symmetrical to the collecting tube axis. However, the separating element can also be arranged in the collecting tube as desired to be displaced to the collecting tube axis, so that any arrangement within the collecting tube is possible. The separating element can be arranged to the Sammelrohrachse such that the separating element forms an angle a with the Sammelrohrachse. The separating element can enclose an angle a of 0 to 40 degrees, preferably of 0 to 30 degrees with the collecting tube axis. In particular, the separating element can be aligned with the separating section along the collecting tube axis, for example, be aligned in parallel so that the angle a is 0 degrees. The separating section of the separating element can thus be aligned exactly at the collecting tube axis, ie the collecting tube axis can lie over an entire collecting tube length in the separating element. The separator can be attached to the manifold, for example, the

Separating element welded to the manifold or glued. However, the separating element can also be connected by means of a fastening element with the manifold, for example, the separating element can be arranged in a guide rail in the manifold or clamped in the manifold, stapled or screwed. However, the separating element can also be arranged without fastening elements in the manifold.

The separating element is embodied and arranged in the collecting tube such that the separating element moves the collecting tube into an outflow region, in which the outflow opening is arranged, into an inflow region, in which the

Inflow opening is arranged and divided into a first deflection region in which the deflection openings are arranged. The separating element can divide the first group of planes in the collecting tube into a plurality of spatially separated first planes with outflow openings, with inflow openings and deflection openings. The separating element can thus advantageously subdivide the collecting tube into a plurality of functional regions, so that a plurality of functions, For example, a deflection of the fluid and an inflow and a

Outflow of the fluid can be realized in a manifold.

In the manifold, a fluid, so a heat transfer medium, for example, coolant, flow. Due to the collecting pipe according to the invention, the fluid can for example flow in a preferred forced direction only in a certain area. In the outflow region, the fluid can flow, for example, in the direction of a drain opening or the first or second axial end of the collector tube. In the inflow region, the fluid can flow, for example, from the direction of an inlet opening or the first or second axial end of the collecting tube into the collecting tube. In the deflection region, the fluid can flow into the collecting tube at a deflection opening, then be deflected by means of the deflection section and flow out of the collecting tube at another deflection opening. The outflow and / or the inflow and / or the first deflection region can be connected to the flow by means of the leakage openings.

The advantage is that due to the separating element in a simple manner, a functional subdivision of the manifold can be created so that discrete inflow, outflow and deflection are realized in the manifold. The inventive collecting tube with a functional

Classification is thus easy to manufacture. In addition, no

additional components, such as bends or distribution pipes, needed or it will be components, ie fittings or other facilities for

Redirecting the fluid saved so that the manifold is inexpensive to manufacture. Likewise, the manifold can be designed differently and so for example reduces the wall thickness or the size of the manifold compared to known sizes and designs or

be advantageously adapted to certain applications. In a refinement of the invention, a first end element is arranged at a first axial end and / or a second end element is arranged at a second axial end, wherein the first and the second end element seal the collecting tube in a sealing manner. The

Collecting tube comprises an inlet opening and / or a drain opening. Through the inlet opening, a fluid flows into the collecting pipe and / or the fluid flows out of the collecting pipe through the discharge opening. At the inlet opening an inlet is arranged and the inlet is at an angle b to

Arranged Sammelrohrachse and / or at the drain opening a drain is arranged and the drain is arranged at an angle c to Sammelrohrachse.

The collecting tube can be closed, for example, at the first and at the second axial end by means of the first and second closing element. For example, the first and second end members may be formed as a hemispherical termination. In addition, a cylindrical section may be formed on the hemispherical termination. An outer diameter of the cylindrical portion may correspond, for example, to an inner diameter of the collecting tube or vice versa. The first and / or second closing element can be arranged on the manifold. The first and / or second closing element can be fastened to the manifold, for example welded, screwed or glued. However, the first and / or second closing element can also be connected by means of a fastening element with the collecting tube, for example, the first and / or second closing element can be arranged and clamped, stapled or riveted to the manifold. The first and / or second final element can also without

Fasteners are arranged on the manifold. Between the first and second end member and the manifold can

For example, each be arranged a sealing element, so that the axial ends of the manifold can be sealed in a sealing manner. Likewise, an air opening, for example a bore, may be present in the first or second end element. The air opening can

be closed and be open, so that, for example, air in the

Can flow manifold. The inlet opening and outlet opening can both be arranged at the first or second axial end on the first or second end element of the collecting tube. Likewise, only the drain opening can be arranged at the first or second axial end on the first or second closing element and the inlet opening can be arranged on the lateral surface of the collecting tube, or vice versa. But it can also be arranged on the lateral surface of the manifold, the inlet and outlet opening. The inlet and

Drain opening may be formed as a hole or a punched hole. The shape of the inlet and outlet opening may be, for example, circular, oval or polygonal. Through the inlet opening, a fluid can flow into the collecting tube, in particular a liquid or gaseous fluid, for example a

Heat transfer medium. Through the drain opening, the fluid can flow out of the manifold. At the inlet opening, an inlet can be arranged. Likewise, a drain can be arranged at the drain opening, through which the fluid flows out of the collecting tube. Inlet and outlet can be connections, for example for lines. To the inlet, a supply line can be connected, through which the fluid is passed to the manifold. To the drain can drain line

be connected, through which the fluid is led away from the manifold. The inlet can be arranged at an angle b, wherein the angle b between the header axis and a straight line can be enclosed by an opening in the inlet. The angle b may be 0 to 90 degrees, preferably between 20 to 90 degrees, and more preferably 50 to 90 degrees. The process can be arranged at an angle c, wherein the angle c between the header axis and a straight line can be enclosed by an opening in the drain. The angle c can be 0 to 90 degrees, preferably between 0 to 50 degrees, and particularly preferably 0 to 30 degrees. Advantage of this embodiment is that the manifold can be modular. Thus, the execution of the manifold, so the

Arrangement of the first or second end element and the inlet and outlet opening and inlet and outlet, varies and adapted to different applications. In addition, the manifold can be produced inexpensively due to this modular design.

In an embodiment of the invention, a baffle plate is arranged on the separating element. The baffle plate is designed and arranged such that the inlet opening in the inflow region and the drain opening in

Outflow area are arranged. The baffle plate may be formed as a part of the partition member, so that the baffle plate is formed, for example, as a folded end piece of the partition member.

The baffle plate can be arranged in the direction of the first or second axial end. The

Baffle plate may be circular, rectangular or polygonal, in particular, the baffle plate may consist of a rectangular and a semi-circular portion. The baffle plate may be disposed towards the first or second axial end of the manifold at the separator, preferably, the semicircular portion may be oriented toward the first or second axial end. In addition, the baffle plate can be arranged such that the inlet opening in the inflow region and the discharge opening are arranged in the outflow region. But it can also a plurality of baffles, for example a first baffle at one end of the separator and a second baffle at the other end of the separator. The baffle plate can be arranged at an angle h, wherein the angle h between the collecting tube axis and the baffle plate can be formed. The angle h can be between 0 and 140 degrees, preferably between 20 and 70 degrees. advantageously,

The first end plate may be arranged in the direction of the first or second axial end of the collecting tube on the separating element, Preferably, the semicircular first end plate can be aligned in the direction of the first axial end on the separating element. The first

End plate can be arranged at an angle d to Sammelrohrachse, the angle d between the Sammelrohrachse and the first end plate can be formed. The angle d can be between 0 and 140 degrees, preferably between 50 and 100 degrees and particularly preferably between 80 and 100 degrees.

The first end plate may be configured and arranged such that the first or second end element and the first end plate form an overflow region. In the overflow region, an overflow opening can be arranged, so that the fluid, which is present for example in excess, can advantageously drain from the collecting pipe, in particular the heat exchanger device. In addition, the first end plate, the deflection and the outflow of

Disconnect overflow area. Also, the inflow area and the

Overflow area be fluidly connected. Advantage of the formation of the overflow area and its functional separation from the outflow and deflection is a more effective use of the manifold and thus in turn an increase in the efficiency of the heat exchanger. In an embodiment of the invention, the separating element comprises a

Deflection section, wherein the deflection section is configured such that in the first deflection region, a flow direction of the fluid is deflected.

Of course, the laminated heat exchanger may also contain a plurality of tubes for more than one heat transfer medium, or the tubes may be connected in parallel and / or in series as needed. However, the heat exchanger device may also be a plate or microchannel heat exchanger. A heat transfer element of the microchannel heat exchanger may for example be designed as an extruded profile, which is made of a material with good thermal conductivity, such as aluminum.

Due to the deflection tube with the baffle, the fluid can only in a certain range in a preferred

to flow in a forced direction. In the second deflection region, the fluid can be diverted, for example, from a deflection opening into another deflection opening. Thus, advantageously, no additional components, such as bends or distribution pipes needed, so that the deflection tube produced inexpensively and easier on a variety of

Applications can be customized.
