Description

Register for a radiator as well

such registers having radiator

The invention relates to registers for a radiator and such a register having radiator.

There are many types of radiators. A classic radiator includes two manifolds, between which extend a plurality of connecting tubes, which the first distribution line, also called flow distributor, with the second distribution line, also called return distributor, fluidly connect.

To determine the specific heating capacity of a radiator, i. the per unit area of the front view of the radiator by radiation and convection delivered to a room heat output, it is known to produce mehrsäulige radiators in which between the flow distributor and the return manifold a plurality of substantially parallel registers arranged out

Extending connecting pipes.

On the one hand, the production of such mehrsäuliger radiator is relatively expensive.

On the other hand, increases the measured perpendicular to the front view thickness of such mehrsäuliger radiator with increasing number of registers (three-Säuler, four-Säuler, five-Säuler, six-Säuler), whereby the flat panel-like or

panel-like character of such powerful multi-column radiator is lost.

The invention has for its object to enable multi-column radiators of the type described above, which on the one hand have a small thickness and yet excellent thermal performance, and on the other

can be produced inexpensively.

To achieve this object, the invention provides a pipe register (RR) ready for a through-flow of a heat transfer fluid heat exchanger (WT), in particular a radiator or heat sink, which has two distribution lines (1, 2) between which a plurality of connecting tubes (3) extend, which the first distribution line, also called flow distributor (1), with the second

Distributor line, also called return manifold (2), connect fluidly, wherein the pipe register has a rectilinear flow distributor (1) and a parallel rectilinear return distributor (2), between which a plurality of connecting tubes (3) extend which are arranged in a plane, wherein the first ends (3a) of the connecting pipes (3) are each fluidly connected to the flow distributor (1) and the second ends (3b) of the

Connecting pipes (3) are each fluidly connected to the return manifold (2). According to the invention, the connection sites (P1) between the supply manifold (1) and the connecting tubes (3) with respect to the central axis (M1) of the flow distributor (1) arranged eccentrically on the flow distributor (1) and the connection locations (P2) between the return manifold (2) and the

Connecting tubes (3) with respect to the central axis (M2) of the return manifold (2) arranged eccentrically on the return manifold (2).

The pipe register (RR) according to the invention appears in a plane of projection orthogonal to the longitudinal axis of the flow distributor and return distributor as a structure approximately in the shape of a rectangular letter C, the projection of the supply distributor (1) forming the upper horizontal portion of the C forms, the projection of the return manifold (2) forms the lower horizontal portion of the C and the projection of the connecting tubes (3) forms the vertical portion of the C.

The inventive tube register thus has only two planes of symmetry. A first plane of symmetry extends orthogonally to the longitudinal axis of the flow distributor (1) and orthogonal to the longitudinal axis of the return distributor (2). A second plane of symmetry extends orthogonally to the longitudinal axis of the connecting tubes (3). With respect to any third plane which extends parallel to the longitudinal axes of the flow distributor (1), the return distributor (2) and the connecting tubes (3), the tube register according to the invention is asymmetrical.

Due to this asymmetry of the tube register (RR) according to the invention, a large variety of heat exchangers (WT) according to the invention can be obtained by combining a plurality of (number n) tube registers (RR1, RR2, RRn) according to the invention. produce, which depending on the relative arrangement of the individual registers (RR1, RR2, RRn) have mutually different dimensions and thermal properties with respect to radiation power and convection.

Moreover, with the inventive pipe register (RR) as a modular base element, a large variety of inventive heat exchanger (WT) can be produced inexpensively.

According to a particularly preferred embodiment, the pipe register (RR) consists of polymer material.

As a result, it is possible to produce particularly lightweight heat exchangers (WT) according to the invention, which have a very high ratio of thermal power

(Radiation + convection) of the heat exchanger to the mass of the heat exchanger have.

The flow distributor (1) and the return distributor (2) may consist of a first polymer material, while the connecting tubes (3) may consist of a second polymer material. Alternatively, the flow distributor (1) and the return distributor (2) and the connecting pipes (3) can be made of the same

Consist of polymer material.

Preferably, the flow distributor (1) and the return distributor (2) and the connecting tubes (3) are produced by extrusion or extrusion tubes, which are welded or glued together at the connecting locations (P1, P2). In the case of a welded connection, ultrasonic welding is preferred.

The invention also provides a heat exchanger (WT), in particular radiator or heat sink, which has a plurality of pipe registers (RR1, RR2, ... RRn) arranged side by side according to one of the preceding paragraphs.

Because of the asymmetry of the inventive pipe register (RR1, RR2, RRn), the combination of several (number n) of such pipe register to a heat exchanger (WT) allows a large variety of inventive heat exchanger (WT), which depending on the relative arrangement of the individual registers (RR1, RR2 , RRn) have mutually different dimensions and thermal properties with regard to radiation power and convection. This great variety Heat exchanger according to the invention (WT) can therefore be produced inexpensively.

Preferably, in the inventive heat exchanger (WT) the

juxtaposed fluid inlets arranged side by side

Supply manifold (1) by means of a flow collector member (S1) with each other

fluidly connected, which forms a fluid connection to the flow port (A1) of the heat exchanger (WT), and arranged side by side

Fluid outlets of the side-by-side return distributors (2) are fluidly connected to each other by means of a return collector member (S2) which forms a fluid connection to the return port (A2) of the heat exchanger (WT).

Preferably, the flow-collecting member (S1) and the return-collecting member (S2) are made of a polymer material and are preferably produced by injection molding.

The asymmetry of the inventive pipe register (RR1, RR2, RRn) and the multiple possibilities, these always identically shaped pipe register as

To arrange low-cost base elements relative to each other, are a first factor, which contributes to the solution of the inventive task.

The variety of heat exchanger variants according to the invention is made possible by a corresponding variety of collection members (1, 2). Due to the above-described symmetries of each pipe register (RR) and the corresponding symmetries of any pipe register combinations and due to the connection of the flow top left and the connection of the return right bottom are the constellations of juxtaposed fluid inlets of juxtaposed flow distributor (1 ) point symmetrical to the

Constellations of juxtaposed fluid outlets of juxtaposed return manifold (2).

It follows that the flow-collecting member (1) and the return-collecting member (2) can have identical shapes. This is a second factor, which contributes to the solution of the inventive task. Consequently, it is necessary for the assembly of a heat exchanger according to the invention only identical inventive tube register in the required number and two equally identical collection elements for merging the flow distributor and the return distributor. Due to their compact dimensions, the collecting elements can be inexpensively manufactured by injection molding.

Preferably, the flow distributor (1) in the region of their fluid connection with the flow-collecting member (S1) glued or welded thereto, and the return manifold (2) are in the region of their fluid connection with the return-collecting member (S2) with this glued or welded.

The heat exchanger (WT) can at least at one of its large areas, i. on its front surface (5) and / or on its rear surface (6) a plate-like

Have cover, which preferably consists of a metal grid and / or a sheet.

This contributes to a homogenization of the surface temperature of e.g. as a wall radiator operated heat exchanger and to a reinforcement of

Chimney effect in the interior at.
