Description

The invention relates to a heat exchanger having a tube register and through which a heat transfer fluid can flow, according to the preamble of claim 1.

A radiator of this type is for example in FR 1 254 959 A described.

There are numerous types of radiators. A classic radiator contains two distributor lines, between which a large number of connecting pipes extend, which fluidly connect the first distributor line, also called the feed distributor, to the second distributor line, also called the return distributor. To determine the specific heating output of a radiator, i.e. To increase the heat output given to a room by radiation and convection per unit area of the front view of the radiator, it is known to manufacture multi-column radiators in which there are a plurality of registers arranged essentially parallel to one another between the flow distributor and the return distributor extend from connecting pipes.

On the one hand, the production of such multi-column radiators is relatively complex. On the other hand, the thickness of such multi-column radiators measured perpendicular to the front view increases with an increasing number of registers (three-column, four-column, five-column, six-column), as a result of which the flat, panel-like or panel-like character of such powerful multi-column radiators is lost.

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

To solve this problem, a heat exchanger according to the technical teaching of claim 1 is provided.

The respective pipe register (RR) appears in a projection plane orthogonal to the longitudinal axis of the feed manifold and return manifold as a structure which has approximately the shape of a rectangular letter C, the projection of the feed manifold (1) covering the upper horizontal section of the C, the projection of the return manifold (2) forms the lower horizontal section of the C and the projection of the connecting pipes (3) forms the vertical section of the C.

The respective pipe register has only two symmetry levels. A first plane of symmetry extends orthogonally to the longitudinal axis of the flow distributor (1) and orthogonally to the longitudinal axis of the return distributor (2). A second plane of symmetry extends orthogonally to the longitudinal axis of the connecting pipes (3). The pipe register according to the invention is asymmetrical with regard to any third plane, which extends parallel to the longitudinal axes of the flow distributor (1), the return distributor (2) and the connecting pipes (3).

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

In addition, a large variety of heat exchangers (WT) according to the invention can be produced inexpensively using the pipe register (RR) as a modular base element.

According to the invention, the pipe register (RR) consists of polymer material.

As a result, particularly light heat exchangers (HE) according to the invention can be produced which have a very high ratio of thermal power (radiation + convection) of the heat exchanger to the mass of the heat exchanger.

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

The feed manifold (1) and the return manifold (2) and the connecting pipes (3) are preferably pipes made by extrusion or extrusion, which are welded or glued to one another 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 a radiator or heat sink, which has a plurality of pipe registers (RR1, RR2, ... RRn) arranged next to one another in accordance with the invention.

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

In the heat exchanger (WT) according to the invention, the fluid inlets of the flow distributors (1) arranged next to one another are preferably fluidly connected to one another by means of a flow collecting element (S1) which provides a fluid connection to the flow connection (A1) of the heat exchanger (WT) forms, and the side-by-side fluid outlets of the side-by-side return manifolds (2) are fluidly connected to each other by means of a return collecting member (S2), which forms a fluid connection to the return port (A2) of the heat exchanger (WT).

The feed collecting member (S1) and the return collecting member (S2) preferably consist of a polymer material and are preferably produced by injection molding.

The asymmetry of the pipe registers according to the invention (RR1, RR2, ..., RRn) and the several possibilities for arranging these pipe registers, which are always of the same shape, as inexpensive basic elements relative to one another, are a first factor which contributes to the solution of the object according to the invention.

The variety of heat exchanger variants according to the invention is made possible by a corresponding variety of collecting elements (1, 2). Due to the symmetries of each individual pipe register (RR) described above and the corresponding symmetries of any pipe register combination, as well as the connection of the flow on the top left and the connection of the return on the bottom right, the constellations of the fluid inlets arranged next to each other are the flow distributors arranged next to each other (1 ) point symmetrical to the constellations of the fluid outlets of the return manifolds (2) arranged next to each other.

It follows that the forward collecting member (1) and the return collecting member (2) can have identical shapes. This is a second factor which contributes to the achievement of the object according to the invention.

Consequently, the assembly of a heat exchanger according to the invention requires only the identical number of pipe registers according to the invention in the required number and also two identical collecting elements for merging the flow distributors and the return distributors. Due to their compact dimensions, the collecting members can be manufactured inexpensively by injection molding.

Preferably, the feed manifolds (1) are glued or welded to the feed manifold (S1) in the area of their fluid connection, and the return manifolds (2) are in the area of their fluid connection to the return manifold (S2) glued or welded.

According to the invention, the heat exchanger (WT) has at least one of its large areas, i.e. on its front surface (5) and / or on its rear surface (6) on a plate-like cover element, which consists of a metal grid and / or a sheet metal.

This contributes to a homogenization of the surface temperature of e.g. as a wall-mounted radiator and to enhance the chimney effect inside.
