Abstract

The present invention forms a hot water pipe that is fixed by attaching aluminum tape to the bottom of the heat sink of the hot water panel by using an ellipsoid with a flat top and bottom sides, and makes contact with the long side of the bottom of the heat sink to maximize the contact area with the heat sink. The space between the heat sink and the semi-circular left and right sides of the ellipsoid hot water pipe, which is formed by attaching the aluminum tape to the bottom of the heat sink, is reduced when the ellipsoid hot water pipe with the top and bottom long sides is flat with aluminum tape. Since the amount of air in the interspace becomes smaller, even if the hot water pipe is heated, a small amount of air in the interspace is thermally expanded, which prevents the heat sink from swelling as in the prior art and is exposed to both indentation connections at one end of the hot water panel.

Description

A hot water panel having improved heat conductivity for an ondol

The present invention relates to a hot water panel for ondol which has improved thermal conductivity used for ondol by laying on the floor of a building.

Usually, the hot water pipe used inside the hot water panel is a circular copper tube. The hot copper pipe is a circular copper tube, which is fixed by attaching the copper copper tube to the bottom of the heat sink of the hot water panel with aluminum tape, and then urethane foaming. Since the contact area with the heat sink is extremely small, the thermal conductivity is lowered. When the hot water pipe is placed on the bottom of the heat sink and bonded with aluminum tape, the hot water pipe is circular and it is inconvenient to attach the hot water pipe to the heat sink. As shown in FIG. 3A, a space is formed between the upper portions of both the circular body hot water pipes and the heat sink, so that the air inside the space between the hot water pipes is expanded when the hot water pipe is heated, and the heat sink swells upward. Widen the contact area When forming the pipe body is oval was very Nan to addition to connecting the ends of mutual connection for hot water to the hot water panels match each other, the oval referred to as oval and elliptical connection.

In order to solve these problems, the present invention forms a hot water pipe that is fixed by attaching aluminum tape to the bottom of the heat sink of the hot water panel as an aluminum tape so that the top and bottom side surfaces are formed in an ellipsoid having a flat surface, and then contact the long side surface of the heat sink to the bottom of the heat sink. Heat conductivity by maximizing the contact area of the upper and lower sides of the heat sink and ellipsoidal hot water pipe formed by attaching the aluminum tape to the bottom of the heat sink. Since the space between the small and small air space in the space is small, even if the hot water pipe is heated, a small amount of air in the interspace becomes thermal expansion, so as to prevent the swelling of the heat sink as in the past, both sides of the hot water panel Exposed as recessed connections The connecting end of the elliptical body hot water pipe is formed into a circular body, and when the multiple hot water panels are interconnected, the connection work is simplified by simply aligning the centers of both circular bodies with the circular body connecting end of the hot water pipe.

In a well-known hot water panel in which a hot water pipe is fixed to the bottom of the heat sink (1) as an aluminum tape (3), and a moisture proof paper (5) is attached to the entire bottom surface of the panel, and the entire interior thereof is filled with a urethane foam layer (4). The hot water pipe installed inside is formed by the ellipsoidal body (2) whose upper and lower sides are flat, and the connecting end of the elliptical body hot water pipe (2) exposed to both recessed connection portions of one end of the hot water panel is formed by the circular body (2a). Reference numeral 6 denotes a fixed plate.

The present invention having such a configuration is made by forming an ellipsoidal body (2) whose upper and lower long sides are flat and formed by attaching and fixing a hot water pipe attached and fixed with aluminum tape (3) to be in contact with the bottom surface of the heat sink (1) of the hot water panel. Since the upper side is in contact with the heat sink, the contact area of the hot water pipe is maximized to improve the thermal conductivity of the hot water pipe, and the entire upper side of the elliptical body is placed on the bottom surface of the heat sink 1 so that the flat upper side is in contact with the aluminum tape. 3) The space between the heat sink and the semicircular left and right end surface of the ellipsoidal water pipe becomes smaller by attaching the flat lower surface and the semicircle left and right end surfaces to the heat sink. This decreases the amount of air in the interspace, so even if the hot water pipe is heated, a small amount of air in the interspace is thermally expanded. Like this, it is possible to prevent the upper heat sink of the panel from swelling. Also, when the hot water pipe is adhered to the bottom of the heat sink with aluminum tape, the upper surface of the ellipsoid hot water pipe is in contact with the bottom of the heat sink. Since the tape is glued, the adhesive work is convenient and the work efficiency is also improved.

And since the connection end of the ellipsoidal hot water pipe (2) exposed to both inlet connection portions of one end of the hot water panel interconnecting the hot water pipes when installing multiple hot water panels was formed into a circular body (2a), the circular body connection end Only by aligning the centers of both circular bodies, it is easy to interconnect the hot water pipes.
