Description

[Detailed Description of the Invention] The present invention relates to a heat exchange device for a circulating pot used in hot water facilities such as baths.

A conventional heat exchange device for a circulating boiler has a heat receiving section provided inside and an ice chamber formed around the outer periphery of the heat receiving section. A device consisting of a heating water canister is widely used and is already known (see Japanese Patent Publication No. 46-2633).

In the above-mentioned conventional heat exchange equipment, most of the heat absorption is done in the heating water jacket, and the purpose of the ice chamber is mainly to prevent the outer wall from being heated, so the heat absorption from the ice chamber is incidental. It was something.

Therefore, there was a drawback that the heat-absorbing area as a whole was insufficient and the heat exchange efficiency was low.

Therefore, it is common practice to use a heating water can with a large number of fins attached to its outer periphery.

However, in this case, the heat exchange efficiency could not be sufficiently increased because the heat absorbed by the fins was only transferred to the heating water jacket.

These fins are attached to the heated water cannula and fixed using adhesive means or welding means such as seam welding, so they have the disadvantage of requiring a lot of effort and cost to manufacture, as well as being susceptible to heating, etc. During use, the adhesive or welded parts may be damaged, resulting in not only lack of durability but also
Another drawback is that poor adhesion or welding results in difficulty in heat transfer from the fins to the heating water jacket.

The present invention improves and eliminates the above-mentioned drawbacks of the conventional heat exchange device of this type, and includes a heat receiving section provided inside and an ice chamber formed around the outer periphery of the heat exchange device. In a heat exchange device for a circulation pot, the heat exchange device is composed of an inner wall and a suitable number of heating water canals having both ends thereof opened toward the ice chamber, and the inner wall and heating water canals are connected by a large number of heat-absorbing fins. Moreover, the heat-receiving part constructed in this way is made of aluminum die-casting so that the whole is integrated, and the ice chamber is made of heat-resistant grooves in the outer shell that correspond to the upper and lower ends of the inner wall. By providing a heat exchange device for a circulating pot that is formed between the inner wall and the outer shell by fitting the upper and lower ends of the inner wall with adhesive and pressing, the heat exchanger is functionally The objective is to provide a device that has excellent exchange efficiency, is strong and durable, and is extremely easy to manufacture.

The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

In FIGS. 1 and 2, 2 is a heat receiving part of the heat exchange device 1 in the circulation pot, and heated water @ 4 is provided in a sealed manner inside the inner wall 3, and heated with the inner surfaces of the inner walls 3 and 3 on both sides. The outer peripheral surface of the water canopy 4 is connected to the outer circumferential surface of the water cannula 4 by a large number of heat absorbing fins 5.

The heat receiving part 2 is integrally formed by die-casting aluminum.

Reference numeral 6 denotes an outer shell of the heat exchange device 1, which has a shape suitable for fitting the upper and lower ends 7, 7 of the inner wall 3 of the heat receiving section 2 into the inner periphery of the upper and lower openings, which have large upper and lower surfaces. circumferential groove 8,
8 and a circulation port 9 on the side.

After applying a heat-resistant adhesive such as silicone adhesive to the upper and lower ends 7, 7 of the inner wall 3 of the heat receiving part 2, the circumferential grooves 8, 8 of the outer shell 6 are fitted to the upper and lower ends 7, 7. By pressing,
When the fitting portion of the heat receiving part 2 and the outer shell 6 are joined in a watertight manner, the heat exchange device 1 is integrated.

An ice chamber 10 surrounding the heat receiving part 2 is formed between the inner wall 3 and the outer shell 6 of the heat receiving part 2.

Both ends of the heating water cannula 4 are opened toward the water chamber 10.

The heat exchange device 1 made in this way is placed on the support stand 11, and the burner 12 is inserted to assemble the circulation pot.

13 is a chimney mounting base placed on the upper part of the outer shell 6,
It is integrated with the outer shell 6 or is separate from it.

In short, the inner wall 3, heated water @ 4, and fins 5 in this embodiment
Since the inner wall 3 and the outer shell 6 are separate bodies, the heat receiving part 2 can be integrally molded with aluminum die-casting, eliminating complicated welding work. A watertight 10 is formed between the inner wall 3 and the outer shell 6 by fitting the provided circumferential groove 8.8 to the upper and lower ends 7, 7 of the inner wall 3 via a heat-resistant adhesive and pressing. It is easy to manufacture.

Moreover, in the heat exchange device 1 manufactured in this way, the heat absorbed by the heat absorbing fins 5 is absorbed by the heating water mantle 4.
Since the heat is transmitted not only to the inner wall 3 but also to the inner wall 3, the efficiency of heat exchange increases dramatically.

Furthermore, the heat receiving part 2 is integrally molded by die-casting aluminum, so that it is strong and durable.

In addition, in the above embodiment, there was one heating water canister 4, but
Depending on the mode of implementation, it is also possible to use a plurality of pieces.

In addition, the case where the heat absorption fins 5 are connected to the inner wall 3 and the heating water mantle 4 has been explained, but as mentioned above, when a plurality of heating water mantles 4 are used, the inner wall 3 is connected to the heating water @ 4 and the heating water @ 4 comrades. Just do it.

As explained above, in the heat exchange device of the present invention, the inner wall and the heating water cannula are connected by a large number of heat-absorbing fins to form the heat receiving section, and the heat absorbed by the heat-absorbing fins is absorbed not only from the heating water mantle. Since the heat is also transmitted to the inner walls, the efficiency of heat exchange increases dramatically.

In addition, in conventional heat exchange devices with fins, as mentioned above, installing the fins required a lot of effort and was technically difficult, so fins were not used to connect the heating water canal and the inner wall. However, in the present invention, as described above, the heat receiving part is integrally formed by die-casting aluminum, and a structure in which the inner wall and the heating water canopy are connected by heat absorbing fins can be easily obtained.

In addition, since the heat receiving part of the present invention is manufactured using the aluminum die-casting method, it is extremely easy to manufacture, and there is no risk of the part being damaged during use when attaching heat absorbing fins as in the past. Overall, it is strong and durable.

For this reason, there is no risk of heat transfer failure due to damage to parts when installing heat absorbing fins, unlike in the conventional case.

Furthermore, the heat exchange device is constructed by fitting the upper and lower ends of the inner wall into the grooves of the outer shell, which has the advantage that assembly of the heat exchange device is extremely simple.
