Description

Hot water boiler having easy assembled solar collector}

The present invention relates to a water heater having a solar heat collecting plate that is easy to assemble, and in particular, each component is modular and expandable, and has a temperature rising effect on the physical properties of the heat collecting tube, and thus, a solar water heater that is easy to assemble, which directly heats filled water (fluid). It is about.

In general, the heat collecting method of solar water heater is made of flat plate type and vacuum tube type.

The plate-type heat collecting plate is an indirect type using a heat medium (antifreeze), which not only lowers thermal efficiency, but may also adversely affect a human body when a heat pollutant, which is an environmental pollutant, is in this case almost impossible to A / S. In addition, since the heat medium is used, in order to raise the temperature of the water in the hot water tank, a heat exchanger must be installed inside the tank or a double tank must be manufactured so that frequent breakdowns and breakages in the hot water tank occur, which causes inconvenience to the user.

In addition, the vacuum tube type has two types, the double glass type and the heat pipe type. The double glass type has severe glass breakage due to rapid temperature change, so when the vacuum tube breaks, the water inside the hot water tank flows out from the broken part to the outside.

In addition, in the heat pipe method, there is a severe crack in the condenser portion of the heat pipe and the junction portion of the vacuum tube.

The two methods such as the flat plate collector and the vacuum tube are deadly at the time of the occurrence of defects and are therefore almost impossible to repair. .

In addition, the conventional solar water heater as described above has a disadvantage in that it is impossible to expand and install the capacity of the solar water heater according to the user's purpose of use because it is manufactured according to its capacity and installation place in advance.

The purpose of the present invention for solving the above problems is to use a heat pipe or heat pipe containing heat pipes used to collect solar heat, without using a method such as welding to connect each part when manufacturing a solar water heater. It prevents environmental pollution that may occur in case of damage in advance, and the user can arbitrarily set the capacity and installation location of solar water heater, each part is modularized and expandable, and it has a temperature rising effect on the properties of the heat collecting tube. Its purpose is to provide a water heater that is easy to assemble to directly heat water (fluid).

Are formed to be continuously connected on the same plane with each other and cut to the required length,

The header 22 has a plurality of nipples 221 vertically penetrating in the inner diameter direction so that the individual collecting pipes 21 are fitted into the nipples 221 and are coupled to each other. There is an accommodating part 222 which is largely processed to insert an inserting part of another header 22, and an inserting part 223 inserted into the accommodating part 222 of the other header 22 protrudes from the other end. The support part 224 for supporting the nipple 221 is configured to protrude outward to extend the capacity by a necessary amount.

The present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view showing the overall appearance of the present invention, there is shown a hot water tank (1) and a solar heat collecting plate (2) connected to the pipe,

In the illustrated heat collecting plate 2, a heat collecting tube 21 cut to a required length is shown, and a plurality of upper / lower headers 22 coupled with the heat collecting tube 21 are shown.

Moreover, the case 23 which fixes and supports this header 22 and the heat collecting tube 21, and the glass 24 which covers the upper surface of this case 23 are shown, and have a flat structure.

When the heat collecting plate 2 configured as described above is installed at a predetermined angle with respect to the sun, the water (fluid) filled with a polymer compound such as EPDM constituting the heat collecting tube 21 is filled in according to the amount of solar radiation supplied. The hot water flows into the hot water tank 1 along the direction shown by the arrow on the right side, and water that does not reach a certain amount of heat flows out in the direction indicated on the left side to be convection.

2 is an exploded perspective view showing the combination of the header 22 and the heat collecting tube 21 of the present invention, Figure 3 is a plan view showing the combination of the upper / lower header 22 and the heat collecting tube 21 of the present invention, 4 is a front view of the subject innovation header 22,

The header 22 of the present invention is configured to insert a plurality of nipples 221 (Nipples) vertically penetrating in the inner diameter direction so that the individual collecting pipes 21 are fitted to the nipples 221 and coupled to each other. After arranging the nipples 221 at intervals of the heat collecting tube 21, a polymer compound or other material such as EPDM is poured into a mold and extruded to make a single body.

In addition, both sides of the header 22 are processed differently so that they can be continuously combined as many times as necessary, one end is processed to a larger diameter than the inner diameter inside the insertion portion 223 of the other header 22 can be fitted There is a payment part 222, the other end is formed with an insertion portion 223 is inserted into the receiving portion 222 of the other header 22 protruding, the support portion 224 for supporting the nipple 221 is toward the outside It is formed to protrude.

Therefore, the plurality of headers 22 may be combined and continuously expanded using an adhesive or other coupling means depending on the material of the headers 22.

FIG. 5 is a front view showing a part of the present invention heat collecting tube 21. The empty heat collecting tube 21 is made of a polymer compound (Epdm, etc.), which is a material in which internal water (fluid) is heated by solar heat. Each of the heat collecting tubes 21 may be continuously arranged at a predetermined distance, and the bottom surfaces 211 may be continuously connected to each other on the same surface to cut the required length.

The reason why the individual collecting tubes 21 are connected through the lower bottom 211 of the collecting tube 21 is that when the individual collecting tubes 21 are inserted into the nipples 221 of the header 22, the respective collecting houses 21 are connected. If the heat pipe 21 is made of a single pipe, a lot of work time and processes are required when assembling, thus eliminating this disadvantage and simply cutting the bottom 211 between the heat collecting pipes 21 according to the user's requirements. This is to secondaryly absorb solar heat reflected by the side surface of the heat collecting tube 21.

6 is a side view of the header 22 and the heat collecting tube 21 of the present invention, the nipple 221 of the header of the present invention 22 is simply assembled when inserted into the inner diameter of the collecting pipe 21 in a closed manner, If the adhesive is used for sealing depending on the conditions, it becomes more robust.

Among the polymer compounds used in the present invention, EPDM having a temperature raising effect has excellent physical properties for ozone resistance, weather resistance, heat resistance, oxidation resistance, low temperature characteristics, electrical properties, and polar substances, and is an automotive part (water strips) and a body. Sealing, Radiator hoses, Heater hoses, Silencer mounts, Protectors, Radiator packing, Brake system, Lamp packing It is used for impact reinforcement materials such as packing, tire & tube, bumper hose,

In general, commercially available EPDM (Ethylene-Propylene-Dienemethylene) is composed of the following structural formula.

The general method for preparing EPDM having such a structure is made by copolymerizing ethylene and propylene with a Ziegler type catalyst, which can be vulcanized with sulfur, and since the double bonds have side chains, they are not significantly affected by ozone resistance and weather resistance. .

These properties do not mention the physical properties of the temperature of the fluid flowing inside the tube when the EPDM is in the form of a tube when the solar heat is supplied from the outside. It was used.

Of course, any of materials having such a temperature increase effect may be used in the present invention.

As shown in the table, when using the EPDM synthetic rubber of the present invention, the temperature increase result was about 80 ° C.

Therefore, when seeing these results, the present invention can be seen that there is no problem in using EPDM in the form of a tube to cover the water using solar heat.

That is, when the heat collecting plate 2 is made using EPDM synthetic rubber, the manufacturing cost is low, and it is very light and easy to maintain, and there is almost no problem in manufacturing use.

And since it can be manufactured by direct heating without using heat medium (antifreeze), it has considerably higher thermal efficiency than indirect heating type and excellent low temperature characteristics, so it can solve the freezing problem of heat collecting plate (2) due to winter temperature drop. Because of its excellent ozone resistance, there is almost no deformation of the material even when exposed to sunlight for a long time.

And because the material is flexible, it does not matter whether it is manufactured in any form (length width) or in any place.

The solar water heater of the present invention as described above is provided with a case 23 and a glass 24 covered therein of the heat collecting plate 2 according to the user's purpose, by cutting the heat collecting tube 21 to fit here, Stable hot water is inserted into the nipple 221 of the upper and lower headers 22 combined as necessary and connected to the hot water tank 1 by assembling a flow path, and using a support lamp so as to be set at an angle in the direction of the sun. Will be supplied.

Since the present invention is a direct heating type, the thermal efficiency is high, and since the copper plate or aluminum is not used as in the conventional heat collecting plate, the production cost is low. As it does not use heat contaminant (antifreeze), which is an environmental pollutant, it does not need to be plated or coated on the surface of the heat collecting plate to absorb solar heat like the existing heat collecting plate. Easy and convenient, low cost, good low temperature, no fear of freezing in winter, good ozone resistance, no deterioration when exposed to sunlight for a long time, and header and heat collection tube can be folded and stored for long time This has the advantage of being easy.
