Abstract

Disclosed is a panel heater (1) with a front plate (2) in which a lower collecting duct (13, 70) and an upper collecting duct (14) running parallel to this and heating ducts (15) between the collecting ducts are formed, with an inlet connection (47) on an underside (27) of the plate heater (1), at least one of the heating channels (15) being a riser channel (18) which carries a heating medium from the underside (27) to an upper side (5) of the plate heater (1) conducts, and with a control valve on the top (5), which regulates a volume flow of the heating medium from the front plate (2) into a rear heating plate (4) of the plate heater (1). A method for passing a heating medium through such a panel heating element (1) is also disclosed. In order to reduce the variety of models, it is proposed that the panel radiator (1) have an alternative inlet connection (29) on the underside (27), from which the heating medium can be guided into the front plate (2) and that the heating medium proceeding from the inlet connection (47 ) is fed through an alternative inlet connection (29) into the front panel (2).

Description

The invention initially relates to a panel radiator having a front plate, in which a lower collecting channel and an upper collecting channel extending parallel thereto and heating channels are formed between the collecting channels, with a feed connection to a lower side of the panel heating element, wherein at least one of the heating channels is a riser channel a heating means from the bottom to a top of the plate radiator passes, and with a control valve on the top, which regulates a volume flow of the heating medium from the front panel in a rear heating plate of the plate heater Furthermore, the invention relates to a method for guiding a heating medium through such a panel heater.

Method and plate heater of the aforementioned type are generally known under the name "serial radiator". By way of example, the manufacturer HM, Dingelstädt / DE (www.muhr.net) avoids separate pipelines with the two-plate radiator offered on the market under the product name "Centara" by introducing the heating medium into the lower collecting duct of the front panel, passing through the heating ducts to the upper collecting duct and from the upper collecting channel via the control valve in the other heating plate - with reverse flow to the return port - is passed.

The known serial panel radiators have an inlet connection laterally (usually with a view from the room to be heated right, rarely left on the radiator) or centrally on the bottom. The lateral connection is standard in many old buildings, the central connection is increasingly prevailing for new buildings. The manufacturer for installers who both modernize old buildings and equip new buildings, must produce both (or even three) models for each dimension, the installer must provide storage space accordingly.

In the broader context of the invention disclosed DE 10 2007 020 628 A1 a plate radiator with parallel-flow heating plates, which has a connection set with alternative inlet and return connections, wherein the inlet connections are connected by a channel and only the lateral inlet connection is connected to the control valve. The return connections are connected to both heating plates.

task

The invention has for its object to reduce the variety of models.

solution

Starting from the known panel radiator is proposed according to the invention that this has an alternative inlet connection at the bottom, from which the heating means in the front panel is conductive. An inventive panel radiator can then be acted upon alternatively via one of the two inlet connections with the heating means. If a plate radiator according to the invention also has alternative return connections, it can be removed from the plate heating element according to the invention via this alternative, the returning heating medium.

Preferably, a panel heater according to the invention has a channel between the inlet connection and the alternative inlet connection, which directs the heating medium from the inlet connection to the alternative inlet connection, wherein the riser channel directs the heating medium from the alternative inlet connection to the top. At such a panel heater according to the invention only the alternative inlet connection must be connected to the front panel. If an inventive panel radiator with alternative return connections also has a channel between them, then only one of the return connections also has to be connected to the heating panel.

Alternatively, the inlet connections of a panel heater according to the invention may be unconnected, so that in the middle connection, the heating medium is introduced into a central riser channel and lateral connection in a lateral riser channel of the front panel.

An inventive panel radiator with a channel between the inlet connections particularly preferably has a connection part with the inlet connection, a return connection, the alternative inlet connection and an alternative return connection, as well as with a first connection tube, by means of which the front plate is connected to the alternative inlet connection, with a second connection tube , By means of which the heating plate is connected to the alternative return port and with a guided through the return port bypass, by means of which the inlet port is connected to the alternative inlet port. Such a connection part advantageously has a cast center piece, in which the Heizmittelkanäle are formed.

Starting from the known methods, it is proposed according to the invention that the heating means is conducted from the inlet connection through an alternative inlet connection into the front plate. The erfidungsgemäße method is with a novel Panel radiator executed and is characterized by the advantages listed there.
