EP1752719A1 - Radiator with partial load function - Google Patents

Abstract

The radiator has shut-off valve assemblies (a-d) arranged between heating plates (11, 21) in respective upper and lower lateral end sections,. The assemblies have T-pieces, where the targeted flow directions are locked at the plate (21) with the assemblies (a, b), and are locked at the plate (11) with the assembly (d), by locking plates. The assemblies (c, d) are connected together by a return pipe (e) that crosses the assembly (d).

Description

The invention relates to a multi-row radiator, in particular a flat radiator according to the preamble of claim 1, with partial load function.
Radiators with facilities for directional guidance of the heating medium to achieve a partial load function are already known. This is intended to ensure that during the heating process, preferably, the heating plate which is directed into the space to be heated flows through the heating medium, thus resulting in rapid sensible heating.

Such radiators are used for example in the EP 1 227 290 B1 . DE 32 16 922 C2 . DE 20 2004 019 163 U1 . DE 20 2004 017 628 U1 and the DE-PS 2517611 described.

In the EP 1227 290 B1 In one embodiment, in one of the transverse channels, an insert part is arranged in the region of a preliminary passage, wherein the feed water can be conducted to the other transverse channel through the insert part. In another embodiment, an insert is arranged in the region of a connecting piece in one of the transverse channels, wherein the insert part prevents overflow of the heating water from the transverse channel into the connecting piece.
In the other documents similar solutions are described with various inserts.

A disadvantage of these solutions is that before fitting nipple valve and shut-off the corresponding inserts must be used according to installation instructions in the connection tees.

Therefore, the object of the present invention is to provide the user with a finished and universally connectable radiator, which is operable in partial load function. This advantageously also connection errors can be excluded that affect the partial load function.

According to the invention, this object is solved by the features of claim 1. In the accompanying claims 2 to 6 preferred embodiments of the invention are included.

Accordingly, the invention comprises a multi-row radiator, in particular a flat radiator with a flow connection and a return port and a first flowed through and preferably facing the space to be heated radiator plate and at least one further flowed through and preferably arranged behind the plate. Between the heating plates, connection fittings are arranged on each upper side end section and on the lower side end sections, the upper connection fittings being substantially identical. The connection fittings consist of T-pieces, with the upper connection fittings, which are closed to the rear heating plate flow directions and closed at a lower Anschlußgarnitur, the direction of the front heating plate flow direction, the lower Anschlußgarnituren are connected by a return pipe and the return pipe thwarts one of the lower connection fittings. Advantageously, the heating medium flow can be introduced via the right or left upper connection fitting, depending on the connection location.
Unwanted flow directions in the connection fittings are prevented by locking disks are provided therein. Only the return connection fitting has no locking disc. The locking discs can be provided with leaking openings.
The return of the heating medium takes place via the return pipe arranged between the lower connection fittings.
The connection of the radiator can take place according to a preferred feature arbitrarily reciprocal or equilateral to the heating circuit.

The invention will be explained in more detail with reference to the figures shown in the drawings. In this case, further advantages of the present invention are disclosed.

FIG. 1 shows a double-row flat radiator (10) with a flow connection and a return connection and a first radiator plate (11) through which the space to be heated flows and another plate (21) flowed through and preferably behind, and between the heating plates (11 , 21) on each upper side end portion arranged terminal sets (a, b) and arranged at the lower side end portions Anschlußgarnituren (c, d). The connection fittings (a, b) are formed substantially the same. The connection fittings (a, b, c, d) consist of T-pieces, wherein in the connection fittings (a, b), which are closed to the rear heating plate (21) directed flow directions with locking discs and the connection set (d), the front heating plate (11) directed flow direction is also closed with a locking disc. The locking discs may be provided depending on the connection with a leak. These openings are used for venting or emptying the radiator. The connection fittings (c, d) are connected to each other by a return pipe (e), the return pipe (e) crossing the connection fitting (c), so that the heating medium flows remain separate from the front to the rear plate and from the connecting return pipe (e) ( Figs. 2 and 5). Depending on the point of connection, the heating medium supply VL can be introduced via the connection set (a) or (b) (Fig.3 or 4). The connection of the radiator can take place according to a preferred feature arbitrarily reciprocal or equilateral to the heating circuit. The heating medium from the heating flow VL thus flows, depending on the type of connection, into the flow connection a or also b (FIGS. 3 and 4). Since the flow path to the rear plate 21 in the upper connection fittings a, b is blocked, the heating medium must flow into the front plate 11, in which the heating medium partially cools. At the lower end of the front plate 11, the heating medium flows through the terminal fitting c from the front plate 11 into the rear plate 21 without coming into communication with the heating medium from the return pipe e. The connection fitting c is a conventional overflow T-piece with the leading to the return connection plugged return pipe e. In c the paths of the heating medium can intersect (from the front to the rear plate and from the connection set d to the return connection (connection set c) without mixing since the paths are separated.) D is an overflow of the heating medium from the front to the back In the rear plate 21, the heating medium rises due to its still existing temperature upwards, cools down completely and leaves the rear plate 21 via the connection set d Depending on the connection location of the heating return, leaves the heating medium (RL) either directly via the connection set d (Fig. 2) or via the return pipe e to the connection set c (Fig. 5) and leaves the radiator there.
