(Configuration of conventional example and its problems) In general, the heat exchanger of a forced air supply/exhaust type oil hot air heater exchanges heat with a combustion tube 2 that combusts the combustion gas ejected from a burner 1, as shown in Fig. 6. It consists of a thin tube 4, a header 8 that is integrally engaged with the combustion tube 2 and the heat exchanger thin tube 4, and a header lid 3 that is provided around the header so as to airtightly cover it. For example, the header lid 3 is formed of a press-molded thin plate, and local heating occurs on the inside of the header lid 3 facing the opening of the combustion tube 2 due to direct impact of the combustion flame. If heat-resistant steel is used for the entire header lid, the cost will be high, so a heat shield plate 11 is generally provided to prevent local heating. This results in an increase in the number of component parts and an increase in assembly time, resulting in an increase in the cost of the heat exchanger. On the other hand, when the header cover 3 is made of an aluminized steel plate, the heat shield plate 11
Depending on when the header cover is covered, the temperature of the header cover must be lowered, which causes problems such as the average temperature becomes smaller, the amount of heat exchanged by the header cover 3 decreases, and the performance of the heat exchanger deteriorates.

In addition, in forced air supply and exhaust type oil hot air heaters where the load on the burner 1's flame opening is large, the combustion noise tends to become louder, but the header lid 3, which is located in a position facing the flame opening, has a tendency to increase the sound pressure. Although it is the largest and occupies an extremely important part in terms of sound insulation, it is made of pressed material and is thin. As a result, there was a problem that the sound insulation was poor and the noise level of the equipment was high.

(Explanation of an Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 5, taking the case of a heat exchanger for a hot air heater as an example. 1 is a burner, 2 is a combustion tube of the heat exchanger. , 4 is a heat exchanger tube, 5 is an exhaust cover, and 6 is an exhaust pipe. The combustion tube 2 and the heat exchange capillary tube 4 are connected and fixed to a header 8 by means of a hook or the like. Reference numeral 3 denotes a header lid provided at a position facing the burner 1, which covers the openings of the combustion tube 2 and the heat exchange capillary tube 4, and is airtightly provided around the header 8 to communicate the combustion tube 2 and the heat exchange capillary tube 4. I'm letting you do it.

In the above configuration, the header lid 3 has a plurality of heat transfer fins 3a integrally formed on the inner and outer surfaces of the surface facing the combustion cylinder opening, perpendicular to the surface and parallel to the direction of air blowing by the blower 7 provided at the top. The header cover 3 is made of a thick material such as cast iron (FIGS. 3 and 5). Since the header lid 3 is made of a thick material, the amount of heat conducted in the surface direction is increased, and the temperature difference is reduced and the temperature is made uniform. Therefore, local heating is eliminated and the average temperature of the header lid is increased, providing a highly efficient heat exchanger. In addition, the heat transfer fin has a fin efficiency of 70
Even at ~80%, the heat transfer area is approximately twice that of the case without fins, and plays an important role in effective heat exchange. Furthermore, since the heat transfer fins are provided integrally with the header lid 3, they work very efficiently without any thermal resistance at the joint surface unlike those joined by welding or the like.

Furthermore, although sound easily passes through thin plates, it can be significantly reduced by increasing the mass and strength by using thick materials as described above. In other words, if the header cover 3 is a thin plate, it can be prevented from becoming a wave due to the difference in specific acoustic resistance, but since sound waves have mechanical force, they cause the thin plate to vibrate as a whole, and not as a compressional wave. It becomes the overall vibrational energy and is re-radiated as sound wave energy, as if the sound wave had passed through it as it is. On the other hand, the thick iron casting header lid 3 of the present invention can significantly reduce the noise. This is because the sound energy is attenuated in the heat exchanger and only a weak amount of energy comes out.

In general, the sound insulation of a single wall depends on its weight.
Since this is uniquely determined, iron castings with a large mass as in this example are superior.

In addition, heat transfer fins are provided on the inner and outer surfaces of the header lid 3, which not only increases the heat transfer area and increases the amount of heat transferred in the header lid 3, but also has the effect of integrally providing the fins. This increases the strength and increases the mass per area, which has a great sound attenuation effect.

(Effects of the Invention) As is clear from the above description of the embodiments, the present invention includes forming the header lid from a thick material, and forming fins on the inner and outer surfaces of the surface of the lid facing the burner. This not only makes it possible to prevent local heating and improve heat exchange efficiency due to the high heat dispersion efficiency, but also makes the entire header lid stronger, making it more resistant to vibration both locally and as a whole. Therefore, there is no need to provide a heat shield plate or the like on the inner surface of the header lid, and it is possible to provide a heat exchanger that is simple to assemble and is inexpensive. In addition, unlike when a heat shield is installed, the temperature on the outer surface of the header lid does not drop, so the average temperature can be set high, providing a highly efficient heat exchanger, and further strengthening the header lid and reducing its weight. The effects are great, such as the ability to create a quiet heat exchanger by improving the sound insulation effect by increasing the amount of heat exchanger.
