Hot water supply apparatus using solar heat and heating evaporation system having the same

The present invention relates to a hot water supply device and a heating evaporation system, and more particularly, to a hot water supply device using solar heat to increase the efficiency of hot water supply by enabling the cold water to be quickly heated through solar heat, and a heating evaporation system having the same is about

As the shortage of fossil fuels such as coal, oil, and natural gas is intensifying, natural energy such as hydropower, wind power, tidal power, and solar heat is attracting attention in recent years.

Natural energy is not only provided indefinitely, but also environmental pollution caused by combustion gas is prevented, so its utilization is gradually expanding.

However, the use of hydraulic power, wind power and tidal power can be applied only in specialized areas, and there is a problem that it is difficult to apply because a large-scale facility is required.

For this reason, the utilization of solar heat, which can be used only with relatively simple facilities in most areas, is increasing.

On the other hand, there is a 'hot water supply device' as disclosed in Korean Patent Application Laid-Open No. 10-2011-0017643 (published on February 22, 2011) as one of the devices using solar heat.

The hot water supply device using solar heat can supply hot water because the cold water moving along the pipe is heated by the heat of sunlight reflected from the heat collecting plate.

However, the conventional hot water supply device using solar heat has a problem in that the heating of the cold water through the heat collecting plate is insufficient, and it takes a considerable time for the cold water to become hot, so that the hot water supply efficiency is lowered.

For the above reasons, in the related field, attempts have been made to develop a hot water supply device using solar heat to increase the efficiency of hot water supply by enabling smooth heating of cold water through solar heat, but no satisfactory results have been obtained so far.

' should be interpreted as a meaning and concept consistent with the technical idea of the present invention based on the principle.

In addition, the embodiments described in the present specification and the configurations shown in the drawings are merely preferred embodiments of the present invention, and do not represent all of the technical spirit of the present invention. It should be understood that there may be examples of equivalents and variations.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

As shown in FIG. 1 , the hot water supply device 100 using solar heat according to the present invention includes a heat collecting plate 110 ; spiral tube 120; and a condensing lens 130 .

The heat collecting plate 110 of the present invention has a shape concave downward, and a reflector 111 is provided on the inner surface.

Accordingly, as sunlight applied to the inside of the heat collecting plate 110 is reflected by the reflector 111 , it is guided in one direction, for example, to the upper part of the center.

In this case, the reflector 111 may be of any general type as long as it can reflect sunlight, and an example thereof may be a mirror.

In addition, the heat collecting plate 110 includes a radial support 112 formed so as to extend from the upper center to the edge, as shown in FIG. 3 .

Accordingly, as the spiral tube 120 is mounted on the support 112 , the spiral tube 120 is fixedly installed in the upper center of the heat collecting plate 110 .

At this time, the support 112 includes a cone-shaped cover 113 in which the top is partially cut.

Accordingly, as the heat of sunlight reflected by the reflector 111 is trapped by the cover 113, water heating in the spiral tube 120 located inside the cover 113 can be smoothly heated as well as the condensing lens The sunlight concentrated by the 130 is smoothly transmitted to the upper end of the spiral tube 120 located inside the cover 113 .

Here, the cover 113 includes a thermally conductive finish plate 113a that blocks the opening of the lower portion.

Accordingly, it is possible to fill the inside of the cover 113 with the metal bead 113b to be described below, as well as facilitate heat transfer to the metal bead 113b.

At this time, the finishing plate 113a may be of any type as long as it is thermally conductive, and examples thereof may be an aluminum plate or a copper plate.

And the cover 113 includes a metal bead (113b) filled therein.

Therefore, since the spiral tube 120 fixedly installed inside the cover 113 is wrapped with the metal bead 113b, the water inside the spiral tube 120 is smoothly heated by the heat transferred from the metal bead 113b.

In this case, the metal bead 113b may be of any general type as long as it is thermally conductive, and may be, for example, an aluminum bead or a copper bead.

In addition, the heat collecting plate 110 may additionally rotate in the front-rear direction, the left-right direction, or the front-back and left-right directions by driving the driving unit 114 .

Therefore, by rotating the heat collecting plate 110 according to the position of the sun, the inner surface of the heat collecting plate 110 faces the sun, so that sunlight can be smoothly introduced into the heat collecting plate 110 .

At this time, the driving unit 114 may have any conventional structure and method as long as it allows the heat collecting plate 110 to rotate in the front-back direction, left-right direction, or front-to-back and left-right directions. Detailed description of the driver 114 is omit

The spiral tube 120 of the present invention is fixedly installed on the central upper portion of the heat collecting plate 110 .

Accordingly, sunlight reflected from the inner surface of the heat collecting plate 110 intensively strikes the spiral tube 120 .

And the spiral pipe 120 is connected to the water inlet pipe 121 at the lower end, and the water outlet pipe 122 is connected to the upper end.

Therefore, the water flowing into the heat collecting pipe through the water inlet pipe 121, more specifically, the cold water is heated by the heat of sunlight reflected from the inner surface of the heat collecting plate 110 to be heated and then the water outlet pipe 122. leaked out through

At this time, the water inlet pipe 121 and the water outlet pipe 122 are fixed to the support 112 to prevent the flow of the water inlet pipe 121 and the water outlet pipe 122 as well as the sunlight to the heat collecting plate 110 . The interference by the water inlet pipe 121 and the water outlet pipe 122 is minimized when reaching the

And the spiral tube 120 is formed in a conical shape with a lower width W1 wider than the upper width W2.

Accordingly, due to the morphological characteristics of the spiral tube 120 , particularly, relatively high temperature water is concentrated at the upper end of the spiral tube 120 among water heated by the heat of sunlight reflected from the inner surface of the heat collecting plate 110 .

The condensing lens 130 of the present invention is fixedly installed on the spiral tube 120 , and the upper end of the conical spiral tube 120 serves as a focusing focus.

Accordingly, water at the upper end of the spiral tube 120 using the heat of sunlight concentrated by the condensing lens 130 , more specifically, water heated by the heat of sunlight reflected from the inner surface of the heat collecting plate 110 . Since the relatively hot water is heated, the water temperature rises faster than when cold water is heated.

At this time, the condensing lens 130 is fixedly installed on the spiral tube 120 by being mounted on the holder 131 formed to protrude above the support 112 of the heat collecting plate 110 .

In addition, the condensing lens 130 may be of any general type as long as it allows sunlight to be concentrated to the upper end of the spiral tube 120 , and an example thereof may be a convex lens.

On the other hand, as shown in FIG. 8, the heating evaporation system 200 according to the present invention includes a hot water supply device 100 using solar heat; connector 210; heating surface 220; and a water storage tank 230;

The hot water supply device 100 using solar heat of the present invention has been described in detail above, further description will be omitted.

However, a plurality of hot water supply devices 100 using solar heat are placed in a zigzag form in order.

Therefore, the hot water is repeatedly heated by introducing the hot water flowing out from the hot water supply device 100 using the priority solar heat from the hot water supply device 100 using the next priority solar heat.

The connection pipe 210 of the present invention is coupled to each between the water outlet pipe 122 of the hot water supply device 100 using the priority solar heat and the water inlet pipe 121 of the hot water supply device 100 using the next priority solar heat. .

Therefore, the hot water flowing out from the hot water supply device 100 using the senior solar heat by the connection pipe 210 is introduced into the hot water supply device 100 using the next priority solar heat.

At this time, the connection pipe 210 may be any type of normal as long as it allows the hot water flowing out from the hot water supply device 100 using the priority solar heat to be introduced into the hot water supply device 100 using the next priority solar heat. , a detailed description of the connection pipe 210 is omitted.

The heating surface 220 of the present invention has a connection pipe 210 buried thereunder.

Therefore, since the heating surface 220 is heated by the heat of the hot water passing through the connection pipe 210, it can be used as a heating means as well as a drying means, for example, a means for drying seawater in a salt farm.

At this time, the heating surface 220 is provided with a frame 221 coupled along the edge, so that the heating element 300 is stably supported by the frame 221 .

In addition, heat loss through the space between the heating surface 220 and the frame 221 is prevented by sealing treatment between the heating surface 220 and the frame 221 , and the inflow of foreign substances is prevented.

In addition, the heating surface 220 may be any type of normal as long as it can generate heat by the heat of the hot water flowing through the connection pipe 210 , and examples thereof may be a ceramic plate or a glass plate.

The water storage tank 230 of the present invention is connected to the water inlet pipe 121 of the hot water supply device 100 using the highest priority solar heat and the water outlet pipe 122 of the hot water supply device 100 using the last priority solar heat.

Accordingly, it is possible to supply water to the hot water supply device 100 using the highest priority solar heat through the water storage tank 230 , as well as recover water from the hot water supply device 100 using the last priority solar heat.

The hot water supply through the hot water supply device 100 using solar heat according to the present invention will be described in detail as follows.

In the present invention, the spiral pipe 120 has a water inlet pipe 121 connected to its lower end and a water outlet pipe 122 connected to its upper end.

Accordingly, water flows along the inside of the spiral tube 120 .

And the spiral tube 120 is fixedly installed in the upper center of the heat collecting plate (110).

At this time, as shown in FIG. 2 , a reflector 111 is provided on the inner surface of the heat collecting plate 110 , and the sunlight applied to the inner surface of the heat collecting plate 110 is reflected by the reflector 111 and concentrated to the upper center of the heat collecting plate 110 in FIG. 5 . As shown in the spiral tube 120, the water flowing along the inner surface of the heat collecting plate 110, more specifically, by the heat of sunlight reflected by the reflector 111 is primarily heated by the heat is heated.

In addition, in the present invention, the support 112 includes a cone-shaped cover 113 , and the heat of sunlight reflected by the reflector 111 is trapped by the cover 113 and located inside the cover 113 . Since it is concentrated into the spiral tube 120 , the water flowing along the inner side of the spiral tube 120 is smoothly heated by the heat of sunlight reflected by the reflector 111 .

However, only the primary heating by the heat collecting plate 110 takes a considerable amount of time to heat the cold water, so that the hot water supply efficiency may be reduced.

However, in the present invention, the condensing lens 130 is fixedly installed on the upper portion of the spiral tube 120 , and as shown in FIG. 6 , the condensing lens 130 concentrates sunlight to the upper end of the spiral tube 120 . Accordingly, since the firstly heated water is heated secondly, the temperature of the water rises rapidly, thereby increasing the hot water supply efficiency.

In addition, as shown in FIG. 4 , the spiral tube 120 of the present invention is formed in a conical shape with a lower width wider than the upper width. Due to the morphological characteristics of the spiral tube 120 , the primary heating process of the heat collecting plate 110 . Since relatively high-temperature water is concentrated at the upper end of the spiral tube 120 in the second heating process by the condensing lens 130, as sunlight is concentrated on the upper end of the spiral tube 120, the water temperature is more rapidly This can increase the efficiency of hot water supply.

At this time, depending on the position of the sun, the primary heating through the heat collecting plate 110 and the secondary heating through the condensing lens 130 may be difficult.

That is, when the inner surface of the heat collecting plate 110 does not face the sun, the amount of sunlight on the inner surface of the heat collecting plate 110 and the amount of sunlight on the condensing lens 130 may be reduced. Secondary heating through the heating and condensing lens 130 may be difficult.

However, in the present invention, the heat collecting plate 110 can be rotated by the driving of the driving unit 114 as shown in FIG. 7 , and more specifically, it can rotate in the front-rear direction, the left-right direction, or the front-back and left-right directions, time and season. Since the inner surface of the heat collecting plate 110 faces the sun by rotating the heat collecting plate 110 in consideration of the sun, the amount of sunlight flowing into the inner surface of the heat collecting plate 110 and the light collecting lens 130 can be stably secured. ) through the primary heating and the secondary heating through the condensing lens 130 can be smooth.

On the other hand, in the heating evaporation system 200 according to the present invention, the hot water supply device 100 using solar heat is arranged in a zigzag shape, and the connection pipe 210 is a water outlet pipe ( 122) and the water inlet pipe 121 of the hot water supply device 100 using the next-order solar heat, respectively, and the heating surface 220 has a connection pipe 210 buried in its lower portion, using the priority solar heat. As the hot water flowing out from the hot water supply device 100 flows into the hot water supply device 100 using the next order solar heat and is heated again, the heat of the heating surface 220 due to the heat of the hot water is smoothly heated, so it is used as a heating means. This is not only smooth, but as it is used as a drying means, drying of the object to be dried is smooth, for example, by supplying seawater 300 to the upper part of the heating surface 220 as shown in FIG. 9 in a salt farm, seawater drying is smooth, that is, sea salt. production can be smooth.
