Definitions
- the present invention relates to a heat exchanger for common use for a boiler and a hot water supply, and more particularly to, a heat exchanger for common use for a boiler and a hot water supply in which a combustion chamber and a common heat exchanger can be used in common when manufacturing a non-condensing, semi- condensing and condensing boiler, to thereby make it possible to manufacture the non- condensing, semi-condensing and condensing boiler.
- a boiler for use in general homes and buildings is used for heating rooms and supplying hot water, which is divided into a fuel oil boiler and a fuel gas boiler, according to a type of fuel used.
- LPG liquified petroleum gas
- LNG liquified natural gas
- a gas boiler can be divided into a variety of types according to a control method or a sealing state thereof. Further, a gas boiler can be classified into a condensing gas boiler and a non-condensing gas boiler according to a method of re ⁇ collecting heat sources heating water.
- a heat exchanger for use in a condensing boiler includes a combustion heat exchanger 29 which heats water directly using heat from a burner 10, and a latent heat exchanger 28 which heats water indirectly using latent heat of an exhaust gas passing through the combustion heat exchanger 29.
- a condensed water basin 32 which externally guides condensed water due to an exhaust gas is provided between the combustion heat exchanger 29 and the latent heat exchanger 28.
- a guide plate 33 slants at the same angle as the condensed water basin 32.
- An exhaust gas discharge portion 36 is formed in opposition to the exhaust gas inlet 31.
- the exhaust gas passing through the combustion heat exchanger 29 flows in via one side of the latent heat exchanger 28 by the condensed water basin 32, passes through latent fin tubes 28', and is discharged via an exhaust gas outlet 37 in an exhaust gas discharge portion 36. Accordingly, heat can be transferred toward the latent heat exchanger 28 for a sufficient time.
- the non-condensing heat exchanger 30 is generally made of a copper material whose heat transfer rate is excellent. Since a high heat efficiency is pursued due to an energy policy and a control technology is developed, the non-condensing heat exchanger is designed to suppress condensation at maximum. However, a condensation phenomenon cannot be prevented from occurring partially or temporarily, which causes the heat exchanger to be corroded.
- the heat exchanger of the condensing boiler shown in FIGs. 1 and 2 differs in its construction from that of the non-condensing boiler shown in FIGs. 3 and 4, due to respectively different heat absorption methods.

- a latent heat exchanger or a non- condensing heat exchanger called an auxiliary heat exchanger
- a heat exchanger for a condensing and non-condensing gas boiler can be manufactured with a common heat exchanger according to the present invention. Accordingly, the heat exchanger for a gas boiler can be manufactured at low cost. Also, since two kinds of heat exchangers can be manufactured with a common heat exchanger, an additional process is not necessary.

- the number of the auxiliary combustion heat fin tubes 310 is generally smaller than that of the combustion heat fin tubes 120.
- the exhaust gas duct 160 has a structure that the volume of the duct is reduced upwards. As a result, the number of the auxiliary combustion heat fin tubes 310 can be reduced and simultaneously a flow of the exhaust gas can be stably guided in the direction of the exhaust gas outlet 161.
- the inner plate members 110, the exhaust gas duct 160, the lateral plate 180, the combustion heat fin tubes 120, and the auxiliary combustion heat fin tubes 310 are sequentially combined one after another and then the auxiliary combustion heat fin tubes 310 and the combustion heat fin tubes 120 are connected with each other via the connection tubes 312, respectively. Accordingly, the non-condensing heat exchanger can be simply assembled.
- the water which is primarily heated by the combustion heat fin tubes 120 flows toward the auxiliary combustion heat fin tubes 310 via the connection tubes 312, and then is secondarily heated by the exhaust gas.
- the water in the lower-side combustion heat fin tubes 120 is heated by combustion heat of the burner 10 via the heat exchanger to which the common heat exchanger in the gas boiler according to the present invention is applied, and then the water in the upper-side auxiliary combustion heat fin tubes 310 is heated.
- the combustion heat fin tubes 120 play a role of a main heat exchanger
- the auxiliary combustion heat fin tubes 310 play a role of an auxiliary heat exchanger.
- the non-condensing gas boiler absorbs only combustion heat in the combustion chamber in order to perform heat exchange.
- the common heat exchanger of the gas boiler according to the present invention can be applied to a downstream combustion gas boiler having a burner which is provided in the upper portion thereof.
- the common heat exchanger according to the present invention can be applied to a general gas boiler in which a gas boiler and a conventional heat exchanger are integrated. That is, the integrated heat exchanger is divided into several heat exchangers and then part of the divided heat exchangers are made of conventional copper heat exchangers and the rest of the divided heat exchangers are made of corrosion-resistant heat exchangers, in which condensed water basin is installed.
- a heat exchanger of a form rolling fin structure according to the present invention can be made by brazing fins on a copper tube, a double tube of a copper tube and an aluminum tube, or a stainless steel tube.
- a heat exchanger structure can be easily varied and modified.
