Definitions

  • the present invention relates to a heat exchanger which provides an exhaust gas discharge system which is more efficient than the heat exchangers in the state of the art.
  • Heat exchangers are used to transfer heat from one fluid to another. Heat exchangers can transfer heat from gas to liquid, liquid to gas, liquid to liquid or gas to gas. Heat exchangers are widely used in cooling, air conditioning, heating, power generation and chemical processes. In other words, the heat exchanger is the circuit element that provides heat transfer among two fluids ⁇ liquid or gas ⁇ with different temperatures without any physical contact therebetween (without mixing).
  • heat exchangers are divided into three types: Tubular heat exchangers, Plate type heat exchangers (Detachable type, Welded type, Semi-welded type, Soldered type), Special purpose heat exchangers (Plate Coil Heat Exchangers, Econocoil Heat Exchangers, Spiral Heat Exchangers). In the combi boilers, the heat exchangers carry out the process of transferring the heat of the burning gas to the liquid.
  • European patent document no. EP2984415B1 an application in the state of the art, discloses a heat exchanger system.
  • the gas burning in the center of the heat exchanger which has a cylindrical body, travels through the helical tubes and is discharged through an external discharge chamber located at the base of the body; and as the gas starts to move through the tubes, the tubes warm up and the liquid in the tubes warm up.
  • the gas passing through the tubes is collected in a separate discharge chamber and then discharged, but this increases the gas pressure value and also reduces the heat exchange efficiency as it slows down the discharge of the gas.
  • European patent document no. EP3485203 an application in the state of the art, discloses a heat exchanger system.
  • the gas burning in the center of the heat exchanger which has a cylindrical body, travels through the helical tubes and is discharged from the body through a channel located at the base of the body; and as the gas starts to move through the tubes, the tubes warm up and the liquid in the tubes warm up.
  • the gas passing through the tubes is collected in a separate discharge chamber and then discharged, but this increases the gas pressure value and also reduces the heat exchange efficiency as it slows down the discharge of the gas.
  • WO 2015/140713 A1 discloses a heat exchanger according to the preamble of claim 1.
  • the objective of the present invention is to provide a heat exchanger that enables the gases burning in the heat exchanger body to move with low pressure.
  • Another objective of the present invention is to provide a heat exchanger that achieves high efficiency within the entire thermal capacity range thanks to the circular gas flow that is generated.
  • a further objective of the present invention is to provide a heat exchanger which ensures that the fluids entering the system are directed to the condensation collection channel, and at the same time, the stability of the combustion efficiency of the burner is achieved in a sustainable manner.
  • the heat exchanger (1) of the present invention essentially comprises
  • the heat exchanger (1) of the present invention comprises a body (2) which is in the form of a hollow cylinder consisting of two parts.
  • the body (2) is preferably manufactured from sheet metal material.
  • the body (2) is made of a heat insulating plastic material.
  • a tube (3) having a spiral structure is arranged inside the body (2).
  • the tube (3) is manufactured as a single piece and is twisted to form spirals.
  • the inlet and outlet parts of the tube (3) can be positioned such that they project from the body (2) or remain inside the body; and the fluid material entering the said tube (3) through the inlet part passes through the spiral structure of the tube (3) inside the body (2) and exits through the outlet part.
  • the flat surface of the body (2) having a cylindrical structure is open and there is provided a front cover (21) having a disc shape for covering the said opening.
  • a burner is placed on the said front cover (21) and the burner is positioned so that the burning part of the burner enters the body (2).
  • a discharge opening (22) is provided on the cylindrical surface of the body (2) to allow the gas exiting the burner to circulate around the tube (3), travel through the cylindrical surface of the body (2) and exit the body (2).
  • the gas discharged from the body (2) through the discharge opening (22) is collected in a second chamber (23) positioned so as to cover the discharge opening (22).
  • the second chamber (23) has a shape parallel to the cylindrical surface of the body (2); in other words, its wide surface is in the form of an arc extending parallel to the body (2). Thanks to its arc shape, the second chamber (22) allows the gas to move at low pressure.
  • the second chamber (23) is in the form of a rectangular prism.
  • a flue opening (25) is provided on the second chamber (23).
  • a plate (24) which partially covers the discharge opening (22) in order to prevent the liquid entering through the flue opening (25) from reaching the tube (3) and at the same time to facilitate the transport of the gas moving on the inner surface of the body (2) to the second chamber (23).
  • the plate (24) has an arc shape and is placed over the discharge opening (22) without completely closing the aperture of the discharge opening (22).
  • the plate (24) has a rectangular shape. The plate (24) prevents rainwater from entering into the body (2) through the flue opening (25).
  • the plate (24) is placed on the discharge opening (22), so that two symmetrical spaces are formed on opposite sides of the plate (24); said spaces are arranged to be symmetrical to each other. Thanks to the said spaces, the gas in the body (2) is allowed to pass into the second chamber (23) in a balanced manner and the gases are enabled to be mixed in a balanced manner.
  • An insulating plate is placed on the flat surface of the cylindrical body (2). The said insulating plate prevents the heat generated by combustion of the burner from heating the flat surface of the body (2), i.e. the wall that cannot be cooled.
  • the heat exchanger (1) of the present invention enables the gases burning in the body (2) to move with low pressure.
  • the hot combustion gasses pass through the apertures of the tube (3) and transfer heat to the liquid passing through the tube (3).
  • the combustion gases which transfer their heat to the liquid within the tube (3), that is to say, which have low energy, are directed from the cylindrical inner surface of the body (2) to the second chamber (23).
  • a plate (24) which partially covers the discharge opening (22) on the second chamber (23), so that the combustion gases can enter the second chamber (23) through a laminar flow.
  • the plate (24) prevents the rainwater or condensate coming from the flue opening (25), i.e. chimney, from directly contacting the burner part where the combustion takes place.
  • the process of directing the combustion gases generated by the burner to the chimney at the flue opening (25) is enabled by the help of a manifold channel provided on the inner wall of the body (2).
  • a manifold channel provided on the inner wall of the body (2).
  • Manifold channel is a solution that allows to reduce the condensing heat exchanger depth as much as the size of the collection chamber.
  • the condensate liquid formed in the chimney and body (2) is directed to the condensate discharge channel provided in the body (2) by following the boundaries set by the manifold channels. This way, the heat exchanger (1) ensures that the fluids entering the body (2) are directed to the condensation collection channel and at the same time, the stability of the combustion efficiency of the burner is achieved in a sustainable manner.
