Definitions
- the invention relates to a heat exchanger according to the preamble of claim 1.
- a heat exchanger of this type for a heater is from the DE 103 06 699 A1 known.
- a substantially cylindrical base body which is produced by casting, executed with a heat-transferred wall.
- the main body has inside a SchuG Kom for serving as a heat-emitting medium heating gas.
- the base body On the outside of the heat-transferring wall, the base body has a helical flow channel for serving as a heat-absorbing medium heating water.
- the Schwarzenkanal as a heat-absorbing flow channel is formed by a molded into the lateral surface of the heat-transferring wall trench, which is surrounded to the outside with a heat transferring wall enclosing a separate enclosure, so that the closed, helical Schumacherkanal results on the outer surface of the base body ,
- the Schumacherkanal is designed over its helical extent with locally different flow cross-sections such that the flow rate of flowing within the heat-receiving flow channel medium to the heat load of the corresponding portion of the heat-transferring wall is adaptable.
- the heating water flowing in the heat-absorbing flow channel is circulated by a pump and supplied to external heat sinks.
- the heating water is used, for example, the space heating or domestic hot water.
- a heater control detects a corresponding drinking water heat demand and actuates a switching valve, which passes the heating water heated in the primary heat exchanger described above via a separate drinking water heat exchanger, also called secondary heat exchanger.
- the heating water cools in the secondary heat exchanger and flows back into the helical flow channels of the primary heat exchanger, while a drinking water stream is heated in the secondary heat exchanger and supplied to the consumer.
- the domestic hot water preparation is therefore on a circulated by a pump heating water flow, a switching valve and instructed a secondary heat exchanger.
- the secondary heat exchanger is usually designed as a plate heat exchanger.
- Object of the present invention is to provide a heat exchanger in which a domestic hot water production accomplished with the least possible additional design effort, dispense with expensive additional components and a risk of failure is minimized.
- the structural design of the heat exchanger is characterized by a in the heating water channel - here called the first heat-absorbing flow channel - arranged separate second heat-absorbing flow channel for a second heat-absorbing medium.
- This second heat-absorbing flow channel substantially follows the helical course of the first heat-absorbing flow channel and is at least partially surrounded by the first heat-absorbing medium.
- the second heat-absorbing medium may be, for example, drinking water.
- the second heat-absorbing flow channel is connected in a heat-conducting manner to the bottom of the first heat-absorbing flow channel.
- the cross-sectional shape of the second heat-absorbing flow channel may be round or elliptical.
- the available free cross-sectional area of the second heat-absorbing flow channel is approximately half the size of the flow-available free cross-sectional area of the first heat-absorbing flow channel.
- the second heat-absorbing flow channel opens at an end face of the base body approximately perpendicular to the first heat-absorbing flow channel and emerges at the opposite end face approximately perpendicularly from the first heat-absorbing flow channel.
- the second flow channel passes through the first flow channel outwardly bounding Strin vom the heat exchanger body, which have recesses for this purpose.
- the second heat-absorbing flow channel has locally different flow cross-sections along its longitudinal extent such that the flow velocity of the second heat-absorbing medium flowing within the second heat-absorbing flow channel matches the heat load of the corresponding region of the second heat-absorbing medium first heat-absorbing flow channel and / or the heat-transferring wall is adaptable.
- the heating of heating water happens as from the DE 103 06 699 A1 known under circulation by means of a circulation pump.
- the heat flow comes from the heat-emitting medium of the SchuKes and flows through the heat-transferring wall and the first heat-receiving flow channel laterally bounding helical rib into the heating water.
- the second flow channel When a request of domestic hot water, the second flow channel is traversed by drinking water, while the heating water is not circulated further.
- the heat flow now flows - coming from the heat-emitting medium of SchuKes, the heat-transferring wall and the helically encircling rib - through the heating water in the second heat-absorbing flow channel and in the drinking water. If the second heat-absorbing flow channel is connected in a heat-conducting manner to the bottom of the first flow channel, heat also flows into the drinking water via this direct contact.
- a heat exchanger which allows both the Schumacherer stiirmung and the domestic hot water preparation by the integration of a second heat-absorbing flow channel in a first heat-absorbing flow channel, dispensing with a secondary heat exchanger and a changeover valve.
- the drinking water is supplied during the domestic hot water production by the supply pressure in the pipeline network, the heating water does not have to be circulated.
- the risk of failing change-over or plate heat exchanger is bypassed as well as a consumption of auxiliary power for the pump operation.
- the drawing shows an embodiment of the invention. It shows the schematic structure of the Grundkörpes with first and second heat-absorbing flow channel of a heat exchanger according to the invention.
- the centrally located heating gas train as a heat-emitting flow channel is recognizable, but not shown in detail.
- the heat exchanger comprises a main body 1 and a separate enclosure 2.
- the main body 1 is through the heat-transferring wall 3 in a heat-emitting flow channel 4 for a heat-emitting medium (heating gas) and in a first heat-absorbing flow channel 5 for a first heat-absorbing medium (heating water) divided.
- the the first heat-absorbing flow channel 5 laterally limiting helical circumferential rib 6 gives the flow channel 5 its characteristic helical course along the heat-transferring wall 3, which is indicated in the lower drawing area by dashed lines.
- a separate second heat-absorbing flow channel 7 here tubular-shaped - arranged for a second heat-absorbing medium (drinking water).
- the second heat-absorbing flow channel 7 is thermally conductively connected to the bottom of the first heat-absorbing flow channel 5 and follows the helical course of the first flow channel 5, which is indicated by dashed lines in the upper drawing area.
- At the end faces 8, 9 of the main body of the second flow channel 7 opens approximately perpendicular to the first flow channel 5 or occurs approximately vertically out of it.
