Description

The innovation relates to a heat exchanger that has a valve for regulating a flow medium, with two collecting ducts and several connecting ducts between them as well as with inlet and outlet nozzles.

Such a structure of the heat exchanger is in the radiators used for space heating and / or convectors known.

For these known heat exchangers are

the most varied of designs and positions of the valve, the inlet and outlet nozzles and a regulating element to the Adjusting the valve has been suggested. For example, it is widely used for the valve, the regulating device for this and to design a fitting available as a separate component for the inlet and outlet nozzles. Such a heating

meaustauschers, e.g. a radiator in which no such component as a separate fitting is required, but in which the individual functions of such a component are integrated in the radiator itself.

The heat exchanger according to the innovation is

characterized in that the valve is located in a collecting duct, the valve seat being connected downstream of at least one connecting duct serving for the flow of the flow medium, and that a regulating element for the valve is connected to this collecting duct at the end of the aforementioned collecting duct Drain nozzles are connected; and in that * i ^ne throttle or partition is to partially or fully & tändigen separation of the flow and return of the flow medium between these ports.

As a result of this aforementioned measure, no extra housing has to be provided for the valve, since the wall of the one manifold itself can form this housing for the valve. Since the regulating element is still connected to one of the collecting ducts and there are inlet and drainage nozzles in the other collecting duct, Such a radiator can advantageously be placed in the room in such a way that the regulating element is on top of the radiator and the inlet and outlet connections are below. This solution is very advantageous because on the one hand the connection lines for the flow and return only protrude over a relatively short distance into a room, and on the other hand the regulating member is more easily accessible. By the measure according to the innovation does not need the inflow and Separate housing part carrying the drainage connection must be provided, since the inlet and drainage connection is the other Sair.mel =

channel of the heat exchanger are connected. It takes also no complicated inner conduit routing formed with a mold core within a separate fitting for separating of Verlsuf flow medium. Return flow medium} because in the heat exchanger according to the innovation this separation of Flow and return can be achieved through a simple wall inserted in the collecting channel. This wall can be made with a Through opening provided or completely closed.

In the drawing, an exemplary embodiment of the object according to the innovation is shown in vertical section.

The embodiment is intended to be a radiator in which the fuselage channels and the connecting channels are made from Pipes exist. This radiator is installed in a room in such a way that it can be regulated or even cooked. 1 at the top and the inlet connection 2 as well as the drain pipe 3 below Ii «» gen. The regulating body 1 A simple handwheel can be designed as a handwheel with a built-in thermostat. This regulating organ 1 is connected at the front to a collecting channel · +. The latter is composed of two duct pieces 5 and 6 and welded together at point 7. A lower collecting duct 8 is closed at the front by a cap 9. Inlet and outlet nozzles 2 and 3 are connected to this collecting channel 8. The two collecting pipes 4 and 8 are connected to one another via several connecting channels 10, 11, 12 and the following, in such a way that these connecting channels are connected to the collecting channels U and 8 via openings 13. At the For example, the heat exchanger described in this way is still surrounded by a housing 14 that does not have a plurality of perforations shown is provided, so that a radiator and convector effective radiator is created.

The valve 15 has a through a into the

Collector tube 4 pressed-in or screwed-in disc 16 is formed Valve seat and a rod 17 connected

slidable valve body having a disc 18. To regulate the flow cross-section of the valve 15, the rod 17 is adjusted longitudinally. Of course, the flow cross-section can also be completely closed will. The channel piece 6 of the collecting canal u can well be machined on a lathe, so that here both the thread 19 for screwing in the disc 16 as well as the End face for this disc 16 to rest flat on an inner shoulder of the channel piece H can be made. In this work, the screwing work for inserting the are from the other end of this channel piece 6 ago Regulatory body 1 made. In the example, the valve seat is therefore located as a separate component fastened in the collecting duct 4 16 before. The regulating element 1 is screwed into one end face of the channel piece 6 with a threaded attachment 20.

The the. Valve seat forming disc 16 is

in the example downstream of the two connecting channels 10 and 11, since these two connecting channels 10 and 11 are in the forward flow of the flow medium, as indicated by the flow arrows is specified. The inlet of a flow medium to the heat exchanger takes place via the inlet nozzle 2. This in The flow medium lying in front enters the space 21 lying between the valve seat 16 and the regulating element 1.

In the exemplary embodiment shown, there is a throttle wall between the inlet connection 2 and the outlet connection 3 22. The latter has an opening 23 which acts as a Uebcrströmkanal (by-pass). About this overflow channel a part of the flow medium can flow from the supply line directly into the return line, namely to the outlet connection 3. The return of the flow medium is also shown with arrows pointing in the connecting channel 12 and in the collecting channel 6 are directed to the right.

This overflow channel 2 3 is available if the heat exchanger in the known manner with a 1-pipe

731648611.10.73

System is used. Beirr, the example shown is this one Flow cross-section of the overflow channel 23 not adjustable, thus of a predetermined size. The throttle wall 22 is welded into the collecting channel 8 and protrudes into the drain connection 3.

The inlet connection 2 lies in the same direction and in the middle between the two connecting channels 10 and 11 in the flow one behind the other in the direction of the collecting duct 8 and in the region of one end of this collecting duct 8.

If the heat exchanger shown is used for a known 2-pipe system, there should be no by-pass between Inlet connection 2 and outlet connection 3 must be present, so so that the overflow channel 23 must be canceled. if this breakthrough 23 is designed as a threaded hole, so this can then be done by simply inserting a screw be locked. This is a very simple option to switch from a 1-pipe system to a 2-pipe system. In return of the heat exchanger are then all connecting channels except the channels 10 and 11, furthermore the channel piece 5 of the Collecting channel H and the one to the left of the wall in the drawing lying part of the collecting channel 8.

There should be reasonable flow conditions

Make possible in the heat exchanger, could also only with a connecting car, so the connecting channel 10, in the lead to be worked. If you want to accept different diameters for the connecting channels, this can of course be done The only connection channel located in the flow can be selected so large that it has the flow cross-section of both connection channels 10 and 11 together. With only one connecting channel in the flow, the channel piece 6 of the collecting channel can then 4 can be made shorter, so that the valve seat 16 is closer to the regulating element 1. Inlet and outlet nozzles 2 and 3 could then also lie even closer to the cover cap 9.
