Expansion tank integrated heat exchanger and boiler having same

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an expansion tank integrated heat exchanger and a boiler including the same, and more particularly, to an expansion tank integrated heat exchanger and a boiler including the same, in which a hot water supply device and an expansion tank are integrally provided in a single heat exchanger casing.

The present invention also relates to an expansion tank integral type heat exchanger and a boiler including the expansion tank, which prevent deformation of the diaphragm constituting the expansion tank and ensure reliable operation of the diaphragm even when used for a long time.

Generally, as the temperature of the heating water circulating in the boiler pipe increases, the volume of the heating water increases and the pressure inside the pipe increases. Therefore, a pressure expansion tank for accommodating the expansion tank should be used.

Accordingly, the boiler needs to separately include the above-described pressure expansion tank in addition to the hot water supply heat exchanger for supplying the hot water, so that it is difficult to manufacture the boiler and the unit price is increased.

As shown in FIG. 1, in Korean Patent Publication No. 2012-0089171, a first casing 110a having a gas chamber on the inside and a second casing 110b having a water chamber on the inside are provided so as to integrally provide a hot water heat exchanger and an expansion tank And the compartment plate 150 is inserted therebetween to partition the water chamber and the gas chamber.

An elastic bag 130a is installed in the first casing 110a filled with the gas and a heat exchange tube 140a for supplying hot water is installed in the second casing 110b in which the heating water flows, 150 are formed with communication holes 151 through which heating water passes.

Therefore, when hot water is supplied by heating the direct water of the hot water supply heat exchange tube 140a by the hot water passing through the second casing 110b and the volume of the hot water is increased by raising the temperature of the hot water, And flows into the second casing 110b through the communication hole 151 of the compartment plate 150 to absorb the impact.

However, in the conventional art as described above, it is possible to prevent a part of the elastic bag 130a from passing through the communication hole 151 and going over to the opposite side, as compared with the case where the size of each communication hole 151 formed in the compartment plate 150 is large There was no way to do that.

Therefore, when the elastic bag 130a is inflated as shown in FIG. 2, the elastic bag 130a is deformed when the elastic bag 130a is inflated and protrudes into the opposite side of the communication hole 151 of the compartment plate 150 for a long time.

When the communication hole 151 of the compartment plate 150 is blocked as described above, the heating water supplied to the water chamber of the second casing 110b pushes the expanded elastic bag 130a to the gas chamber side of the first casing 110a There is a problem that the function of the expansion tank is lost.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above-mentioned problems, and it is an object of the present invention to provide an expansion tank integrated heat exchanger in which a hot water supply device and an expansion tank are integrally provided in a single heat exchanger casing, and a boiler including the same.

It is another object of the present invention to provide an expansion tank integral type heat exchanger that prevents deformation of a diaphragm constituting an expansion tank and guarantees reliable operation of the diaphragm even when used for a long time, and a boiler including the expansion tank.

To this end, the expansion tank integral type heat exchanger according to the present invention and the boiler including the expansion tank have a water chamber in which heating water flows inside, and includes a heating water inlet through which the heating water flows, a heating water outlet through which the heating water is discharged, A water chamber casing including a direct water inlet to be introduced and a hot water outlet to discharge hot water; A gas chamber casing assembled to face the water chamber casing to form a heat exchanger casing and having a gas chamber inside; A partition plate assembled in a boundary portion between the water chamber and the gas chamber in the heat exchanger casing and having a plurality of heating water flow holes formed therein so that the heating water is dispersedly introduced into a specific region of the one side portion; A hot water heat exchange tube assembled between one side of the diaphragm and the water chamber, the inlet of one end being fitted in the direct water inlet of the watercasing casing, and the outlet of the other end being fitted in the hot water outlet of the watercasing casing; And a diaphragm assembled between the other side of the diaphragm and the gas chamber and expanded by the inflation gas filled in the gas chamber or compressed by the heating water flowing into the gas chamber side through the heating water flow hole. do.

At this time, it is preferable that a first support protrusion protrudes along a boundary line of the specific zone on a lower surface of the diaphragm on which the diaphragm is disposed.

In addition, it is preferable that a second support step protrudes between the heated water flow holes in the lower surface of the diaphragm.

Preferably, the plurality of heating water flow holes are formed at predetermined intervals along the circumferential direction in the specific zone, and the boundary line of the specific zone is circular.

In addition, it is preferable that at least one peeling protrusion is protruded from the lower surface of the partition plate where the diaphragm is disposed.

The ends of the diaphragm are curved outward, and the curling of the diaphragm is bent outwardly between the curling of the diaphragm and the curling of the gas chamber casing As shown in Fig.

Hereinafter, an expansion tank integrated heat exchanger and a boiler including the heat exchanger according to preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3, the expansion tank integrated heat exchanger 200 according to the present invention includes a water casing 210, a gas chamber casing 220, a partition plate 230, a hot water heat exchange pipe 240, and a diaphragm 250 . Each of these structures is assembled as shown in FIG.

Accordingly, the water chamber casing 210 and the gas chamber casing 220 are opposed to each other to form a single 'heat exchanger casing', and a diaphragm 230 is installed in the heat exchanger casing to partition the water chamber and the gas chamber.

In addition, a hot water heat exchanger (240) corresponding to a hot water heat exchanger is installed in the water chamber, and a diaphragm (250) corresponding to a pressure type expansion tank is installed in the gas chamber to integrally provide an expansion tank and a heat exchanger.

As described in more detail below, the heating water flow hole 232 formed in the diaphragm 230 is formed in a special structure, and a plurality of support ribs 232b and 232c are formed in the diaphragm 250, And also improves its operating reliability.

More specifically, the watercasing casing 210 is opened at one side and has a water chamber in which heating water flows. That is, a water chamber is formed in a space surrounded by the inner wall surface of the watercasing casing 210.

The watercasing casing 210 is provided with a heating water inlet 211, a heating water outlet 212, a direct water inlet 213 and a hot water outlet 214 and includes an air vent AV do.

For example, the heating water inlet 211 is connected to one side of the watercasing 210, and the other side of the watercasing 210 is connected to a heating water outlet 212. The direct water inlet 213 and the hot water outlet 214 are connected to the side where the heating water outlet 212 is provided.

The heating water inlet 211 and the heating water outlet 212 communicate with the water chamber inside the water casing 210, and a heating water circulation pipe (not shown) of the boiler is connected to the water chamber 211. Therefore, the high-temperature heating water flowing through the heating water inlet 211 passes through the water chamber and is discharged from the heating water outlet 212.

As a result, the high temperature heating water exchanges heat with the hot water heat exchange tube 240 installed in the water chamber, so that the hot water circulating through the hot water heat exchange tube 240 is heated to always prepare hot water.

The direct water inlet 213 and the hot water outlet 214 also communicate with the water chamber inside the water casing 210. Both ends of the hot water heat exchange tube 240 communicate with the direct water inlet 213 and the hot water outlet 213, (214).

However, the pressure receiving portion 210b may be formed on the upper surface of the watercasing casing 210. For example, the pressure receiving portion 210b may have a substantially elliptical shape at the center of the watercasing casing 210 .

Therefore, the volume of the water chamber is increased by the pressure receiving portion 210b. Therefore, when the heating water is instantaneously introduced in a large amount by the pressure receiving portion 210b, the water chamber casing 210 is not damaged do.

The flange portion 210a provided at the lower portion of the watercasing casing 210 is used for coupling with the gascasing casing 220 as described below.

The gas chamber casing 220 is assembled to face the water casing 210 opposite to each other. The flange portion 210a of the waterproof casing 210 is inserted and assembled into the flange portion 220a of the gas chamber casing 220. [

The gas chamber casing 220 is open at one side and has a gas chamber at the inside thereof, like the water casing 210. That is, the gas chamber is formed in the space surrounded by the inner wall surface of the gas chamber casing 220.

A gas inlet 221 is provided at one side of the gas chamber casing 220. The gas inlet 221 is provided so as to communicate with the gas chamber so that nitrogen gas or the like can be injected.

When the gas is injected so that the gas chamber inside the gas chamber casing 220 has a predetermined pressure, the diaphragm 250, which will be described later, is inflated and bulges toward the diaphragm 230 side.

On the other hand, when the temperature of the heating water rises and the pressure of the boiler pipe is higher than the gas chamber pressure, the heating water flows through the heating water flow hole 232 of the diaphragm 230. At this time, the heating water pushes the swollen diaphragm 250 and flows into the gas chamber side, thereby absorbing the shock.

4B, the end of the diaphragm 230 is curled outwardly, the end of the gas chamber casing 220 is curled inwardly, and the end of the diaphragm 250 is curved outwardly And then assembled to be inserted between these curling.

When the diaphragm 250 and the gas chamber casing 220 are inclined outwardly, the volume of the diaphragm 250 that is compressed and expanded during the curling operation is guided to expand outward, Thereby preventing the diaphragm 250 from being detached when it is finished.

Further, the expanded diaphragm 250 can be brought into close contact with the side surface of the gas chamber and the bottom surface of the water chamber to maximize the airtightness performance. When the diaphragm 250 is assembled to the water chamber, it is prevented from being released.

The diaphragm 230 is assembled in the heat exchanger casing at the boundary between the water chamber and the gas chamber. For example, the diaphragm 250 is mounted on the gas chamber casing 220, the diaphragm 250 is fitted on the diaphragm 230, and the water-cooled casing 210, on which the hot water heat exchange tube 240 is assembled, And divides the inside of the base casing.

The diaphragm 230 has a fitting portion 230a that protrudes downward to guide the insertion of the diaphragm 250 along the lower edge of the diaphragm 230. A peeling protrusion 231 is formed on the plate surface, A plurality of heating water flow holes 232 are formed.

At this time, it is preferable that at least one protrusion 231 is formed on the lower face of the diaphragm 230 on which the diaphragm 250 is disposed. 3, the upper surface of the diaphragm 230 is pressed so that the peeling projection 231 protrudes to the lower surface.

The peeling protrusions 231 are formed linearly along the width direction of the partition plate 230 and are provided at regular intervals along the length direction of the partition plate 230.

Therefore, even if the diaphragm 250 is inflated and kept in contact with the diaphragm 230 for a long time, the diaphragm 250 is easily separated by the peeling projection 231. This is because the contact surface area between the diaphragm 250 and the diaphragm 230 is reduced by the peeling protrusion 231. [

Conventionally, when the diaphragm 250 is expanded by the gas, the diaphragm 250 is brought into close contact with the diaphragm 230. When such a state is maintained for a long time, the elastic bag of the rubber material is adhered to the surface of the diaphragm 230.

Therefore, even if the pressure increases due to an increase in the temperature of the heating water, the diaphragm 250 is adhered to the diaphragm 230, so that the diaphragm 250 can not be poured out to the gas chamber side while pushing the diaphragm 250.

Further, when the heating water flows into the water chamber, the peeling protrusion 231 changes the flow direction of the introduced heating water to generate a vortex, thereby increasing the heat exchange rate with the hot water heat exchange tube 240 installed in the water chamber do.

Next, the heating water flow hole 232 of the diaphragm 230 causes the heating water to flow from the water side to the gas chamber side. That is, when the pressure of the boiler pipe increases, the heating water flows into the gas chamber from the water chamber to absorb the shock due to the pressure change. When the pressure of the boiler pipe is lowered, the heating water in the gas chamber is discharged back to the water chamber by the pressure of the gas chamber.

Particularly, in the present invention, a plurality of heating water flow holes 232 are provided, and at this time, a plurality of heating water flow holes 232 are formed in a specific area provided at one side of the diaphragm 230, Flows through the flow holes 232.

As shown in FIG. 5A, the plurality of heating water flow holes 232 are formed at predetermined intervals along the circumferential direction on the installation surface 232a in the specific area. Accordingly, the boundary line of a specific zone is circular.

Instead of using one heating water flow hole (see FIG. 2) having a large diameter as in the prior art, in the present invention, several heating water flow holes 232 having a small diameter are formed in a specific area.

Accordingly, the present invention can significantly reduce the inflow of the same flow rate, but also the expansion of the diaphragm 250 into the opposite side of the water flow hole 232.

Accordingly, the present invention prevents the diaphragm 250 from being deformed to lose its function, and also prevents the diaphragm 250 from interfering with the heating water flow hole 232 to block the heating water flow hole 232.

In addition, as shown in FIG. 5B, it is preferable that a first support protrusion 232b protrudes along the boundary line of the specific area on the lower surface of the diaphragm 230. Since the lower surface of the diaphragm 230 is a surface on which the diaphragm 250 is disposed, the first support step 232b supports the diaphragm 250. [

When the first support step 232b supports the diaphragm 250 and a plurality of heating water flow holes 232 having a small size are formed in the specific area as described above, 250 are prevented from being caught.

When the expanded diaphragm 250 comes into contact with the first support step 232b, the seal is formed at the contact point, thereby preventing the heating water from flowing into the gas chamber in a normal state in which the pressure of the pipe is not higher than the gas chamber pressure .

Furthermore, it is preferable that a second support step 232c protrudes between the heating water flow holes 232 in the lower surface of the diaphragm 230. So that the entire circumference of each heating water flow hole 232 is surrounded by the first support step 232b and the second support step 232c.

The first supporting step 232b is present in the boundary line of the specific region around the heating water flow hole 232 and the second supporting step 232c is present between the heating water flow holes 232 And the periphery thereof has an upward inclined structure (see arrows) around each heating water flow hole 232.

5C, the expanded diaphragm 250 is not supported by the first support step 232b and the second support step 232c and is not inserted into the heating water flow hole 232, So as to ensure smooth operation thereof.

However, the first support step 232b and the second support step 232c may be formed continuously, but they may be formed at regular intervals while maintaining the pattern. For example, the first support step 232b may be formed at regular intervals along the circular pattern instead of being formed in a circular pattern.

On the other hand, the hot water heat exchange tube 240 prevents the user from taking a long time until the cold water comes out or the hot water is supplied when the hot water is used for the first time by preparing the hot water of appropriate temperature at all times in preparation for the user's use of hot water.

To this end, the hot water heat exchange tube 240 is assembled between the diaphragm 230 and the water chamber. That is, the hot water heat exchange tube 240 is assembled in the watercasing casing 210, and is formed into a coil shape having a plurality of turns so as to increase the length of the flow path and perform heat exchange for a sufficient time.

6, the inlet port 241 provided at one end of the hot water heat exchange pipe 240 is fitted into the direct inlet port 213 of the watercasing casing 210, and the outlet port 242 Is fitted into the hot water outlet 214 of the watercasing casing 210.

Therefore, when a direct water pipe (not shown) is connected to the direct water inlet 213 and a hot water pipe (not shown) is connected to the hot water outlet 214, the low temperature direct water supplied through the direct water pipe flows into the hot water heat exchange pipe 240, As shown in FIG.

The direct water supplied to the hot water heat exchange tube 240 is heated by exchanging heat with the hot water filled in the water while circulating the hot water heat exchanger tube 240. The hot water passes through the outlet of the hot water heat exchange tube 240, And is discharged to the hot water pipe through the pipe 242.

The diaphragm 250 corresponds to an elastic bag made of an elastic material. The diaphragm 250 is inflated by a predetermined pressure gas (for example, nitrogen gas) injected into the gas chamber, and eventually serves as a pressure expansion tank.

This diaphragm 250 is assembled between the diaphragm 230 and the gas chamber. That is, the diaphragm 250 is assembled into the gas chamber casing 220.

As shown in FIG. 7, the diaphragm 250 is formed in a lid shape that covers the entire opened upper portion of the gas chamber casing 220, and the upper expansion portion 250a and the lower connection portion 250b.

Therefore, when the pressure due to the heating water is lower than the gas chamber pressure, the expanded state is maintained toward the diaphragm 230 side. On the other hand, when the pressure of the heating water is higher than the gas chamber pressure, it is contracted by the heating water flowing into the gas chamber through the diaphragm 230 from the water chamber.

Hereinafter, the boiler of the present invention including the expansion tank integrated heat exchanger 200 as described above will be described.

The boiler of the present invention is characterized by including the expansion tank integrated heat exchanger 200 of the above-described configuration, and others are well known and can be applied to various boilers.

For example, the boiler includes a boiler body, a burner, a main heat exchanger, an association and the like. Inside the boiler body, not only the expansion tank integrated heat exchanger 200 of the present invention, but also the burner and main heat exchanger described above are installed. The association discharges the combustion gas generated during the burning of the burner to the outside.

In addition, a heating water supply pipe is connected to the heating water inlet 211 of the expansion tank integrated heat exchanger 200, and a heating water discharge pipe is connected to the heating water outlet 212. In addition, the heating water supply pipe is connected to the main heat exchanger, and the heating water discharge pipe extends to the heating space.

Therefore, the heating water flowing into the main heat exchanger is converted into the high-temperature heating water by the flame generated at the time of ignition of the burner and the high-temperature combustion gas, and the high-temperature heating water is supplied through the heating water supply pipe to the number of the expansion tank integrated heat exchanger 200 Respectively.

The high-temperature heating water supplied to the water chamber of the expansion tank integrated heat exchanger 200 performs heat exchange with the low-temperature direct water flowing in the hot water heat exchange tube 240 installed in the water chamber to generate hot water, and the hot water is discharged through the hot water pipe .

It is to be understood, however, that the scope and spirit of the present invention is not limited to these specific embodiments, and that various modifications and changes may be made without departing from the spirit of the present invention. If you have, you will understand.
