At this time, the upstream chamber 23 is a flat box-shaped casing, and the supply pipe 17 for connecting the heating medium supply hose 16 protrudes on the outer wall, and the upstream side end 27 of each of the plurality of heat exchange pipes 13 ) Connected to the upstream end 27 of all the heat exchange tubes 13 into a fluid connection state. The downstream chamber 25 is also in the form of a flat box-shaped casing, the discharge pipe 19 for connecting the heating medium discharge hose 18 protrudes on the outer wall, and the downstream side end of the plurality of heat exchange pipes 13 (29) Connected to each downstream end 29, the downstream end 29 of all heat exchange tubes 13 is integrated into a fluid connection state. At the same time, since the upstream and downstream chambers 23 and 25 are in a box shape, they serve as supporting frames for supporting the upstream end 27 and downstream end 29 of the heat exchange tube 13, respectively. When distributing the distributor 21 in the heat exchange housing 15, it can be arranged in a stacked or contact state with other distributors 21 adjacent to the top, bottom, left, and right.

As another embodiment of the distributor 21 according to the present invention, the distributor 21 shown in FIGS. 5 and 6 has a plurality of heat exchange tubes 13 upstream end 27 connected to the upstream chamber 23, FIG. As shown in Fig. 7, a plurality of heat exchange tubes 13 are arranged in a staggered shape and 13 are arranged side by side, which is the same as the distributor shown in Fig. 4, but both the supply pipe 17 and the discharge pipe 19 are upstream chambers ( 23), the inner space of the upstream chamber 23 is divided into a supply-side compartment 33 and a discharge-side compartment 35 by a plate 31, as shown in FIG. . At this time, of course, the supply pipe 17 is opened (communicated) in the supply-side compartment 33, and the discharge pipe 19 is opened (communicated) in the discharge-side compartment 35. Therefore, a series of heat exchange tubes connected to the supply-side compartment 33 becomes a supply-side heat exchange tube 13-1, and the remaining heat exchange tubes connected to the discharge-side compartment 35 become discharge-side heat exchange tubes 13-2 to be separated from each other. do.

In addition, as illustrated in FIG. 5, the downstream chamber 25 (the other chamber) according to another embodiment is formed in the same box-shaped casing as the downstream chamber 25 illustrated in FIGS. 2 to 4. In addition, by integrating the downstream end (29: the other end) of the plurality of heat exchange tubes 13 into one, all the heat exchange tubes 13 are fluidly connected. However, since the discharge pipe 19 is formed in the upstream chamber 23 (one side chamber) together with the supply pipe 17, unlike the distributor 21 of FIGS. 2 to 4, supply of the heating medium to the upstream chamber 23 and Discharge is possible. Therefore, the heat medium introduced into the upstream chamber 23 through the supply pipe 17 is a supply side heat exchange pipe 13-1, a downstream side chamber 25, and a discharge side heat exchange pipe 13- as shown in FIG. After returning to the upstream chamber 23 via 2), it is discharged to the place of use through the discharge pipe 19.

delete

To this end, the distributors 21 of this embodiment are juxtaposed such that at least two or more are arranged in parallel in a lattice shape in the heat exchange housing 15 of the heat exchange section 5, as shown in FIGS. 9 and 10. In addition, it is not shown, but may be arranged by stacking up and down.

In addition, in order to fluidly connect the two distributors 21 disposed in series as above, as shown in FIGS. 8 and 10, the discharge pipe 21 of the distributor 21 preceding the flow phase (communication path) of the heating medium 19) and the supply pipe 17 of the following distributor 21 are connected by a detachable connection pipe 133. Accordingly, it is possible to continuously (circulate) the heat medium flow between the neighboring distributors 21.
At this time, the distributors 21 are supplied with the heating medium through the supply pipe 17 of the distributor 21 that precedes the communication path of the heating medium among the distributors 21 as shown in FIG. 8.

Divide up and down or back and forth. At this time, in order to arrange the distributor 21 obliquely, of course, the heat inducing member 141 must also be disposed obliquely at the same angle. Accordingly, the distributor 21 can be installed in the heat exchange housing 15 by turning it at an angle of 90 degrees, for example, as shown in FIG. 11, and can be installed at any angle within the range of 0 to 90 degrees. . However, the insertion angle of the distributor 21 is in the range of 90 to 180 degrees is substantially the same as in the range of 0 to 90 degrees, and in the range of 180 to 360 degrees, the distributor 21 is connected to the heat exchange housing 15 It is meaningless to insert it upside down.

Therefore, when the distributor 21 is inserted horizontally, that is, at an angle of 0 degrees, the internal flue W is formed between the adjacent heat conduction members 141 inside the heat exchange housing 15, so that the combustion part during combustion ( The thermal energy transferred from 3) to the internal flue (W) is transferred to the distributor (21) located on the internal flue (W). At this time, since the combustion heat can be directly suppressed by the heat inducing member 141 to be discharged through the flue part 7, the loss of the combustion heat transmitted from the combustion part 3 to the distributor 21 can be greatly reduced. There will be.

As such, the heat inducing member 141 can be installed in the heat exchange housing 15 in various shapes and arrangements to prevent deterioration of combustion heat energy, for example, as shown in FIG. 8, the distribution hole 143 on one side It can be made of perforated plates. When such a plate material is employed as the heat induction member 141, as shown in FIG. 8, two heat induction members 141 are arranged up and down, and the distribution hole 143 of each heat induction member 141 is shown.

In addition, since each heat exchange tube 13 is filled with a heat medium, that is, water is flowed therein, the inside water is heated with heat energy absorbed from the combustion gas to be utilized from the outside.

At this time, the heat exchange unit 5 of the present embodiment, as shown in Figure 9, can be separated from the distributor 21 in the heat exchange housing 15, a large amount of combustion gas on the surface of the heat exchange tube 13 when used for a long time Even if the debris is condensed and attached, the distributor 21 is removed from the heat exchange housing 15 so that the flue gas residue on the surface can be easily removed. However, when the heat medium supply pipe 17 and the heat medium discharge pipe 19 of the distributor 21 are disposed opposite to both ends of the distributor 21, as shown in FIG. 2, the distributor 21 from the heat exchange housing 15 In order to withdraw either one of the supply hose 16 or the discharge hose 18 must first be separated from the distributor 21, the heat medium supply pipe 17 and the discharge pipe 19, as shown in Figure 5 distributor (21) When disposed on the upstream side of the, as shown in Figure 9, either the supply hose 16 or the discharge hose 18, without removing the distributor 21 from the heat exchange housing 15 to remove the distributor 21 It becomes possible.

On the other hand, the above-described boiler 101, as shown in Figures 8 to 10, the internal flue (W) has a multi-layer structure, the internal flue (W) a plurality of distributors (21) juxtaposed side by side on each floor Therefore, it is possible to significantly increase the amount of water that can be heated at one time compared to the boiler 101.

That is, the heat energy and the combustion gas generated due to fuel combustion in the combustion section 3 are moved from the combustion section 3 to the heat exchange section 5 through the distribution hole 143 of the lowest heat induction member 141 in the direction of the arrow. In the process of flowing along the inner flue W of the lowest layer, it contacts the lowest layer distributor 21 disposed in the inner flue W of the lowest layer. Accordingly, the heat medium flowing through the heat exchange tube 13 of the distributor 21 is heated. At this time, as shown in FIGS. 8 and 10, since all the distributors 21 are fluidly connected to the adjacent distributors 21 by the connecting pipes 133, the water heated in the preceding distributors 21 is the trailing distributors 21 ), further heating, and in this way heating is accelerated. Therefore, the water supplied from the water supply source to the first distributor 21 through the supply hose 16 is heated while passing through the neighboring distributors 21 in turn along a streamline connected through the connector 133, and finally It is discharged from the distributor 21 to the place of use through the discharge hose 18.

In addition, as shown in FIG. 9, when a plurality of distribution holes 143 are penetrated, the heat induction member 141 supports the plurality of distributors 21 and discharges combustion gas and heat energy transmitted from the combustion unit 3. At the same time, the combustion gas and thermal energy are allowed to quickly contact each heat exchange tube 13.

At this time, the above-described boiler 101 can be washed after removing the distributor 21 from the heat exchange housing 15. For this, first, in the case of the detachable assembly tool 160 shown in FIG. 13, the nut from the bolt 161 ( After 165 is released, the cover 155 is separated from the housing 15 while the hook 163 is removed from the bolt 161 to open the opening 153. However, in this case, in order to pull out each distributor 21 through the opening 153, the connector 133 connecting the distributor 21 must first be disassembled. However, when each distributor 21 is installed using the cartridge 145 shown in FIG. 12, all the distributors 21 installed on the same layer of the internal year W may be detached at the same time.
