さいものであり。Conventional configurations and their problems Conventionally, in response to energy conservation trends, systems have been devised to improve overall energy efficiency by also recovering exhaust gas heat from heat sources such as engines. As shown in the figure, waste heat is recovered by a heat exchanger 1 and discharged through a muffler 2. However, in such a system, the gas exchanger 1, which recovers exhaust heat from the engine 3, and the muffler 2 are provided separately, which not only makes the system complicated, but also makes the muffler 2
There was a drawback that the sound transmitted from the muffler 2 was large and the muffler 2 had to be large in order to suppress this sound. Still, many conventional heat exchangers for exhaust heat recovery are of the fin type or plate type as shown in FIGS. 2 and 3. In these types, when trying to increase the efficiency of exhaust heat recovery, the exhaust gas condenses and corrosion of the fin and plate surfaces progresses.With fin types, the thin fin plate thickness causes a noticeable drop in heat exchange characteristics. The plate type had problems such as condensed water accumulating in the plate space, further accelerating corrosion. Furthermore, with the plate type, the exhaust gas flow is rapidly reduced in the plate space, and although a slight sound reduction effect is expected, the effect is small because the rate of rapid reduction cannot be increased.

First, the fluid to be heated is sent from the water introduction pipe 12, passes through the water chamber 4, enters the header 〇 through the water passage hole 13, branches into each heat transfer tube 11, flows, and enters the header 7 into the water discharge pipe 14. is discharged through. On the other hand, exhaust gas from a heat source such as an engine, which is a heating fluid, enters the exhaust gas space 6 through the exhaust gas introduction pipe 15, collides with the inner wall of the exhaust gas space 6 and the heat transfer tube 11, and then flows through a plurality of exhaust gas jet ports provided in the exhaust gas pipe 1o. From 17,
The gas enters the exhaust gas pipe 10, passes through the exhaust gas pipe 1o, collides with the exhaust gas pipe partition wall 18, and is ejected from the exhaust gas outlet 19 into the exhaust gas space 5. -Then, after colliding with the inner wall of the exhaust gas space 6 and the heat exchanger tube 11, it passes through the partition plate 9).

The exhaust gas is discharged through the exhaust gas exhaust pipe 16. While the exhaust gas flows through the above-described path, heat is efficiently exchanged with the inner wall of the exhaust gas space 5 and the heat exchanger tubes 11.

音効果も高められる。According to this embodiment, the exhaust gas sent from the engine is rapidly reduced when entering the exhaust gas outlet 17, and
When passing through the exhaust gas pipe 1o and ejecting through the exhaust gas outlet 19, the exhaust gas is rapidly reduced in size, and furthermore, when passing through the partition plate (B) 9, it is also rapidly reduced in size, and then the exhaust gas outlet 20. The exhaust gas exhaust pipe 16 is also rapidly reduced in size, essentially forming a six-stage expansion type muffler, thereby significantly improving the sound reduction effect. Furthermore, all of the expansion mufflers are side input/output types, and their sound reduction characteristics can be expected to be even better. Furthermore, since the exhaust gas space 5 is surrounded by the water chamber 4 having a large mass, the sound insulation effect is also enhanced.

ことができる。Furthermore, in order to divide the exhaust gas space 5 in this way, simply use the partition plates 8. This is possible by simply fixing the partition plate ) 9 to the inner wall of the exhaust gas space 6 or the heat transfer tube 11 at an appropriate distance, so the size of the space can be changed arbitrarily depending on the noise characteristics of the heat source. Yes, you can adjust the sound reduction characteristics. Furthermore, in this embodiment, the exhaust gas outlet is provided in the circumferential direction of the exhaust gas pipe 10;
As a result, the ejected exhaust gas collides with the inner wall of the exhaust gas space 6 and the heat transfer tube 1\1 at high speed in the vertical direction, which suppresses the development of a boundary layer and significantly improves the heat transfer characteristics. . Furthermore, even for engines with different displacements and exhaust heat amounts, the heat transfer area can be easily changed by simply adjusting the length. In addition, with respect to the generation of condensed water, the condensed water generated by vertically standing the heat exchanger of this embodiment is quickly blown out through the partition plate C) 9° exhaust gas outlet and the exhaust gas exhaust pipe 16, and heat is generated. Corrosion of the exchanger can be suppressed.

特性を期待できる。However, the present invention is also directed to a system in which the exhaust gas pipe partition wall 18 is not provided, and in the case of this embodiment, a part of the exhaust gas passes through the inside of the exhaust gas pipe 10 without being transmitted. Thermal performance and sound attenuation properties deteriorate. Therefore,
In this case, the cross-sectional area of the passage in the exhaust gas pipe 10 is set to the exhaust gas outlet 19. The area of the passage hole of the partition plate (B) 9 is smaller than that of the passage hole, and the exhaust gas outlet 1 is
9 into the exhaust gas space 5, and after passing through the partition plate (B) 9, it is made easier to enter the exhaust gas pipe 10 again through the exhaust gas outlet 2o, thereby improving heat transfer and sound reduction performance. In addition, in these embodiments, three partition plates are provided, and six
Although a stage expansion type muffler is formed, if the exhaust gas space 6 is divided into a plurality of sections, the sound reduction characteristics of a side input/output type expansion type muffler can be expected.

Moreover, by surrounding the area with an ice chamber, the sound insulation effect is enhanced, and by easily dividing the exhaust gas space, it is possible to adjust the sound reduction characteristics as desired depending on the noise characteristics of the sound source. Furthermore, regarding heat transfer characteristics, by causing the exhaust gas to collide with the inner wall of the exhaust gas space or the heat transfer tubes at high speed in the vertical direction, the development of a boundary layer can be suppressed and heat transfer performance can be significantly improved.
