Abstract

(57) [Summary] [Purpose] To improve the degree of freedom in the configuration of heat exchangers and to make it possible to manufacture a variety of heat exchangers without spending much time or money. [Structure] Heat receiving fin pipe units 10 as one unit are combined and arranged to form heat exchangers 15 of various sizes.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a heat exchanger for a gas instantaneous water heater used in a gas instantaneous water heater.

0002

[Conventional technology]

FIG. 4 shows the structure of a conventional heat exchanger for a gas instantaneous water heater. This example is heat receiving A large number of heat receiving fins 1 are arranged in parallel, and several heat receiving pipes 2 are passed through these heat receiving fins 1. The heat receiving part is configured by This heat-receiving part receives the heat from the combustion part (not shown) located below. At the same time as the burning flame passes through the heat receiving part, water passes through the heat receiving pipe 2, causing hot water to flow. Obtainable.

0003

[Problem that the idea aims to solve]

Conventional heat exchangers for gas instantaneous water heaters such as these vary depending on the size of the product. I decided on the size. In other words, when the size of the product changes, a new dimension of heat exchange is required. A converter is required. Therefore, the heat receiving fin 1 also needs to be manufactured with new dimensions. . When manufacturing a new heat exchanger, heat receiving fins must be manufactured each time. There was a problem in that it required product development costs, development time, etc.

0004 This invention was made in view of the above problems, and a heat receiving pipe of the same shape is attached to one heat receiving pipe. By arranging multiple heat receivers for heat exchangers with a large number of The purpose is to provide a heat exchanger for gas instantaneous water heaters with improved flexibility. It is.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, this invention has heat receiving fins arranged on a heat receiving pipe. A heat exchanger for a gas instantaneous water heater equipped with multiple heat exchanger heat receivers. The heat receiver for the heat exchanger has multiple heat receiving fins arranged on one heat receiving pipe. It is something.

[0006]

[Effect]

This invention is arranged by combining heat receivers for heat exchangers as one unit, and various Various types of gas instantaneous water heaters are available to create heat exchangers for gas instantaneous water heaters of various sizes. The degree of freedom in configuration when manufacturing a heat exchanger for use is improved. In other words, various types of heat exchangers can be produced without spending a lot of money or taking a long time.

[0007]

【Example】

Below, one embodiment of the heat exchanger for gas instantaneous water heaters of the present invention will be explained with reference to the drawings. do.

[0008] FIG. 1 shows a heat receiving fin pipe unit 10 which is a heat receiver for a heat exchanger. . This heat receiving fin pipe unit 10 is suitable for manufacturing heat exchangers of various sizes. It is a single unit, and can be configured by arranging multiple pieces according to the size of the heat exchanger. It is something that The heat receiving fin pipe unit 10 has a plurality of heat receiving pipes 11 for heat receiving. Fins 12 are provided.

[0009] FIG. 2 shows a configuration in which a heat exchanger 15 is constructed by arranging this heat receiving fin pipe unit 10. It is something that This heat exchanger 15 is configured as described above in the outer body (casing) 16. Four heat receiving fin pipe units 10 are arranged in a row.

0010 FIG. 3 shows a heat exchanger 17 configured by arranging the heat receiving fin pipe unit 10. Here is another example. This heat exchanger 17 has heat-receiving fin pipes inside the outer body (housing) 18. Two levels of units 10, that is, two units at the top and three units below. It is. As can be easily understood from Figs. 2 and 3, heat exchangers of various sizes When manufacturing the exchanger (15, 17), the heat receiving fin pipe unit 1, which is one unit, is 0 can now be arranged and manufactured in combination, making it easier to manufacture various types of heat exchangers. The degree of freedom in configuration (design) is improved.

[0011] In other words, it is now possible to manufacture a wide variety of heat exchangers in a short time, and it is also possible to Since the heat receiving fins are used, mold costs can be reduced. Furthermore, new The development period for heat exchangers for instantaneous gas water heaters can be shortened.

0012

[Effect of the idea]

According to this idea, heat receivers for heat exchangers, which are one unit, are arranged in combination and each Since the heat exchanger is manufactured to the size of a seed, the degree of freedom in its configuration is increased. . In other words, it has the advantage of being able to manufacture a wide variety of heat exchangers without much cost or time. do.
