Definitions

  • the invention relates to a heat exchanger with a housing having a primary inlet port, a primary outlet port, a secondary inlet port and a secondary outlet port, wherein between the primary inlet port and the primary outlet port a primary primary side flow path and between the secondary inlet port and the second outlet port secondary outlet port a secondary secondary side flow path is arranged, wherein the primary flow path with the secondary flow path in heat transferring connection and the heat exchanger has at least one control auxiliary device which is arranged in the primary flow path and in the secondary flow path.
  • Such a heat exchanger is known for example from EP 608 195 B1.
  • a temperature sensor is integrated and measures both the temperature in the primary and secondary flow path.
  • the temperature sensor is located in a cylindrical tube and is in communication with a valve outside the housing.
  • Heat exchangers are used to transfer thermal energy from a primary medium to a secondary medium without mixing the two media.
  • the first medium water of a district heating system and the second medium water in drinking water quality.
  • at least one medium may be gas.
  • auxiliary control devices such as, for example, sensors, which are required for the operation of the heat exchanger, are integrated in the heat exchanger.
  • vulnerabilities are created inside the heat exchanger. If control auxiliary devices, such as sensors, are integrated in a heat exchanger and are arranged in two separate flow paths at the same time, then interfaces are created at the openings from one flow path to the other flow path. There is thus the possibility that the two media come into contact with each other and mix inadvertently. This happens, for example, if one of the interfaces leaks.
  • the invention has the object to improve a heat exchanger constructive.
  • control auxiliary device is passed through a gap which is arranged between the primary flow path and the secondary flow path.
  • the transition regions, and thus the interfaces between the primary flow path and the secondary flow path, are isolated from one another by the primary flow path and the secondary flow path each adjoining the intermediate space.
  • the gap is then between the primary and the secondary side of the heat exchanger.
  • the primary and secondary flow paths are spaced apart in this part of the heat exchanger.
  • the auxiliary control device is guided through the intermediate space and is thus arranged simultaneously in three areas, namely in the intermediate space and in the areas to the right and left of
  • Control aids are here, for example used for controlling or regulating the heat exchanger and act, for example, mechanically or thermally. Also, electrical cables are conceivable, which are guided to a device within the heat exchanger. Should a seal between the primary flow path and the intermediate space or between the secondary flow path and the interspace be leaking, the interspace serves as a location for leakages. Accordingly, fluid which leaves the primary or secondary flow path unintentionally arrives at a defined location. This prevents major damage to the heat exchanger. It is also ensured by the gap that not the fluids of the primary and secondary sides come into contact with each other. Namely, it is unlikely that the interface between the primary flow path and the gap and the interface between the secondary flow path and the gap become leaking at the same time.
  • a monitoring sensor can be arranged, which detects an entry of the fluid into the intermediate space. Thereupon, further measures can be initiated which prevent a major leakage, for example the shut-off of the inlet and outlet lines.
  • the gap communicates with an environment of the housing.
  • the intermediate space can have a small volume.
  • the volume of the gap can then be designed only for small amounts of leakage, as in case of failure, fluid can be passed on to the outside.
  • the heat exchanger is not significantly larger by the gap than a heat exchanger without this gap. If fluid penetrates into the intermediate space, this can evaporate, for example because of its heat and through the adjacent heated primary and secondary sides. It For example, leaks occur when the fluid in the primary line rises to higher temperatures than intended. The fluid then expands due to the elevated temperature and requires more space. At a weak point, such as a seal, the fluid tries to escape. It gives the fluid with the arrangement of the intermediate space a predetermined breaking point.
  • the intermediate space absorbs the fluid and at the same time reduces the overpressure caused by the fluid.
  • the intermediate area relieves the remaining areas of the heat exchanger by the gap is in communication with the environment of the housing, so that an overpressure can escape. Although some fluid is then lost, but there is no longer any danger that other areas of the heat exchanger are affected by a pressure increase.
  • the gap is at least partially bounded by the housing.
  • the housing thus encloses at least a portion of the primary and a portion of the secondary flow path and the space.
  • the gap may be bounded by the walls of the primary and secondary flow paths on its other walls, which are not formed by the housing. It is therefore provided without a lot of material, the gap.
  • the intermediate space has at least one opening which is arranged in the housing.
  • the intermediate space thus directly adjoins the housing and has at least one opening which connects the intermediate space with the environment to the outside. There are thus no channels necessary, which could hinder the drainage or evaporation of leaked fluid.
  • control auxiliary device is a first valve tappet of a first valve.
  • the first valve is thus a cartridge valve, since it is at least partially disposed within the heat exchanger. On This way one achieves a compact design of the heat exchanger.
  • the first valve tappet is arranged simultaneously in at least one actuation position in the primary and secondary flow paths as well as in the intermediate region.
  • the first valve is arranged in the region of the secondary inlet port.
  • the valve is inserted, for example, at the secondary inlet port from the outside into the housing of the heat exchanger and connected against falling out by a screw connection to the housing.
  • the first valve is thus easily replaceable and sufficiently fixed at a resulting overpressure of the fluid.
  • the first valve is thermally stressed, since on the secondary side of the heat exchanger, the fluid is heated by the fluid of the primary side and the fluid at the secondary inlet port has a lower temperature than the secondary outlet port.
  • the primary inlet port comprises a first valve seat of the first valve. It is thus possible to control the inflow of the fluid in the primary inlet port with the first valve. This is particularly easy when the primary inlet port and the secondary
  • Outlet port are arranged opposite and the connections are on a straight line connection.
  • the first valve seat is fixed to the housing arranged in the primary inlet port and seals at the same time with the first valve closed the primary inlet connection from.
  • a first valve member of the first valve which cooperates with the valve seat is conveniently flowable through the primary inlet port.
  • the first valve has a membrane that comes into contact with fluid of the secondary flow path.
  • a membrane responds almost inertia to set pressure changes in the second secondary inlet connection. Accordingly, the first valve has a short reaction time.
  • the first valve stem with the membrane is actuated. It thus uses the almost inertia-free response of the membrane for the valve lifter. Thus, one can influence the fluid flow in the primary flow path without delay in dependence on the fluid flow in the secondary flow path.

  • the control auxiliary device is a temperature sensor.
  • the control auxiliary device is a temperature sensor.
  • the temperature of the fluid inside the heat exchanger You then have the opportunity to make the heat exchanger safer due to a measured temperature. This happens, for example, by monitoring a fluid temperature in the heat exchanger. At too high a temperature of the fluid, measures are taken to protect a user from burns. Also, the room conditions of the heat exchanger is effectively used by an integrated temperature sensor inside the housing.
  • the temperature sensor communicates with the gap via a fluid path.
  • the temperature sensor may, for example, use the gap as reference point for temperature measurement.
  • the temperature sensor may also extend into the intermediate space during a thermal expansion. In this way, no additional space is needed in a warming and prevents a pressure increase due to a material expansion of the temperature sensor.
  • the gap can also serve to equalize the pressure.

  • the sensor space has no connection to another room and is closed.
  • the temperature sensor is in communication with a second valve stem of a second valve.

  • the primary side fluid has a lower temperature than the primary inlet port.
  • the thermal load of the second valve is kept so low.
  • the second valve has a return spring which presses a valve element against a second valve seat, thereby closing the primary outlet port.
  • the return spring causes a counterforce to the force that is generated by the inflowing fluid of the primary flow path to the valve element. If the counterforce of the return spring is overcome, then the second valve is in the open position.
  • the opposing force of the return spring is adjustable, so that you can adjust the second valve to different operating conditions.
  • the heat exchanger has heat exchanger plates, wherein in a first region the primary and secondary flow paths are arranged parallel to one another and in a second region the primary and secondary flow paths are arranged diagonally to one another.
