Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a double pipe connector assembly and a heat exchange structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of heat exchange, and more particularly to a double piping connector assembly and a heat exchange structure using the same.

In recent years, as the atmosphere has deteriorated, interest in ventilation or air cleaning has been increasing day by day. Domestic air pollution from automobiles and factory dust to fine dust is in a serious condition. Accordingly, these days, like the fine dust forecast, forecasts the air quality of the day.

Since the state of the outside air is bad in this way, the room is generally closed. However, since the air quality of the enclosed room is not as good as that of the outside air, it is necessary to purify the room air. Further, even in the case of a heating device such as an electric heater, the indoor / outdoor air is exchanged in order to maintain a good state of the indoor air quality.

However, in the case of a conventional ventilator or an electric heater, since heat exchange of indoor and outdoor air is performed using only a heat exchange element provided in the apparatus, sufficient heat exchange is not performed, and a considerable amount of heat is leaked to the outside.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

BRIEF DESCRIPTION OF THE DRAWINGS FIGURES 1A and 1B illustrate a dual pipe connector assembly in accordance with a preferred embodiment of the present invention. FIGS. 1A and 1B are views for explaining the basic structure in which the connector assembly of the present invention is connected to a dual pipe. FIG. 1A is a sectional view of a state before a plug member and a double pipe are connected, and FIG.

For reference, the connector assembly of the present invention means "a set of connector elements" for connecting dual pipes for heat exchange.

Referring to FIG. 1, a double-pipe connector assembly according to a preferred embodiment of the present invention includes a three-hole elbow member 1 and a plug 2. Further, the preferred embodiment may further include the socket member 4, which will be described below.

Figs. 2A to 2C are views showing a three-hole elbow member 1 employed in the connector assembly of the double piping of the present invention.

The three-hole elbow member (1) includes a tubular body (10). The tubular body 10 includes a first opening 11 formed at one end, a second opening 12 formed at the other end opposite to the first end, and a third opening 13 formed in the body. As in the illustrated example, the three-hole elbow member 1 may be, for example, a T-shaped elbow member, but a pipe connecting member having three holes such as a Y-shape may be applied without particular limitation.

Figs. 3A and 3B are views showing a plug member employed in the connector assembly of the double piping of the present invention. Fig.

The plug member 2 is engaged with the first opening 11 side or the second opening portion 12 side of the three-hole elbow member 1. [ The stopper member 2 seals the external exposure opening H between the internal pipe 52 of the double pipe 5 inserted into the tubular body 10 of the three-hole elbow member 1 and the tubular body 10 It plays a role. The plug member 2 has an opening through which the internal pipe 52 of the double pipe 5 passes for sealing, and the hole is in tight contact with the outer circumferential surface of the internal pipe 52 to maintain the airtightness. Further, although not shown, a separate sealing arrangement may be included for close contact between the hole of the stopper member 2 and the internal pipe 52. The plug member 2 is inserted into the first opening 11 side of the three-hole elbow member 1 and is brought into tight contact with the inner circumferential surface of the tubular body 10 so as to maintain airtightness. Similarly, although not shown, a separate sealing arrangement may be provided for close contact.

Referring back to Figs. 1 and 2a to 2c, a double pipe 5 is connected to the second opening 12 side of the three-hole elbow member 1 employed in the double pipe connector assembly according to the preferred embodiment of the present invention .

In the illustrated example, the internal pipe 52 of the double pipe 5 is arranged so as to pass through the three-hole elbow member 1 as well as the inside of the external pipe 51. Therefore, the third hole elbow member 1 is tightly coupled to the second opening 12 side so as to maintain the airtightness of the outer pipe 51.

The connector assembly of the double piping according to the preferred embodiment of the present invention may further include a socket member 4. [

4 is a view showing a socket member employed in a connector assembly of a dual piping according to a preferred embodiment of the present invention.

The socket member 4 may include an outer linkage 41, an inner linkage 42, and a support 43.

Such a socket member 4 can be used for connection between the double pipes 5 or between the double pipe 5 and the three-hole elbow member 1. [

When the double pipe 5 is connected to the three-hole elbow member 1, the three-hole elbow member 1 is connected to the second opening 12 side of the tubular body 10, . This case is suitable for the case where another internal piping other than the internal piping 52 of the double piping 5 is inserted in the tubular body 10 in the tubular body 10, unlike the example shown in Fig. At this time, the inner joint 42 of the socket member 4 connects the inner pipe inserted in the tubular body 10 and the other inner pipe disposed outside the tubular body so as to be airtight. The external connecting rod 41 connects the side of the second opening 12 of the tubular body 10 of the three-hole elbow member 1 and the other external piping arranged to surround the other internal piping so as to be airtight. A plurality of supporting members 43 are provided to support the inner connecting rod 42 while connecting to the outer connecting rod 41.

FIG. 5 is a view showing an example of connection and connection of the dual pipes 5 using the socket member 4 employed in the preferred embodiment of the present invention.

This socket member 4 can also be used for connection between the double pipes 5 as described above. The inner connecting rod 42 couples the inner pipes 52 to maintain airtightness, and the outer connecting rod 41 couples the outer pipes 51 to maintain airtightness.

Another outer pipe 54 is joined to the third opening 13 of the tubular body 10 of the three-hole elbow member 1 so as to be airtight.

In the above-described structure, cool air flows through the inner pipe 52 and warm air flows between the inner pipe 52 and the outer pipe 51 so that heat exchange can be performed within the double pipe 5.

As described above, the double pipe connector assembly according to the preferred embodiment of the present invention can connect the double pipe 5 to enable heat exchange. Furthermore, since the connector assembly of the double piping can separate the positions of the exhaust and intake air, it can be preferably applied to an air cleaning or ventilation system.

Hereinafter, a heat exchange structure using a dual pipe according to a preferred embodiment of the present invention will be described.

FIG. 6 is a schematic view illustrating a heat exchange structure using a dual pipe according to a preferred embodiment of the present invention.

The heat exchange structure of the present invention can be applied to an example in which the positions of the intake air and the exhaust air are separated, for example, as an electric heater.

As can be seen from Fig. 6, it can be more suitably applied to a configuration in which the positions of the intake air and the exhaust are spaced apart or separated, as in the case of the electric heater E, for example. Elements such as a heat exchange element 61, a filter (not shown), a heating element (not shown), a motor (not shown), and the like may be disposed in the electric heater E.

As shown in FIG. 6, in the case of the electric heater E, the positions of the intake air and the exhaust air must be distant from each other so that they do not mix with each other.

Generally, the electric heater E is provided with the heat exchange element 61, but since a sufficient heat exchange is not performed only by the heat exchange element 61, a considerable amount of heat is leaked to the outside and energy consumption is large.

The present invention can provide a secondary heat exchange area as shown in FIG. 6 by using the above-described double pipe connector assembly. For example, by arranging the double pipe 5 between the first connector assembly C1 and the second connector assembly C2, the air passing through the heat exchange element (primary heat exchange region) is again subjected to secondary heat exchange . The internal piping 52 of the double piping 5 is configured such that both end portions thereof extend into each of the first and second connector assemblies C1 and C2 or the socket member 4 as described above is adopted, Other internal piping can be connected.

Furthermore, since the length of the double pipe 5 can be selected in the heat exchange structure of the present invention, the secondary heat exchange area can be lengthened or shortened according to the situation of the site.

Preferably, the inner pipe 52 of the double pipe 5 may be made of a material having better thermal conductivity than the outer pipe 51. If necessary, the inner pipe 52 may employ a pipe containing a metal component, and may further increase the heat exchange efficiency by selecting a pipe having a large surface area such as a corrugated pipe.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
