Description

[0001] ELECTRIC HEAT PIPE ASSEMBLY [0002]

The present invention relates to a heat transfer pipe assembly, and more particularly, to a heat transfer pipe assembly that facilitates coupling between a heating element and an electrode wire while preventing short circuit thereof, and allows a heating element in a heat transfer pipe to be easily replaced.

Generally, heat pipe assembly is one of the traditional heating devices, which is a type that is laid on the floor of a room where heating is required, so that water heated by the boiler can be heated by circulating the heated water by the pressure of the pump.

On the other hand, the heat transfer pipe uses a heat generating body installed along the inside of the pipe instead of the boiler, and is configured to heat the room using heat generated from the heat generating body.

Thus, the heat transfer pipe is different from the heating means and is comparable to a conventional boiler hot water pipe in that no pump is required.

In this case, the heating element usually has a structure in which the heating wire is heated by the resistance of the wire.

Therefore, in order to receive power, the heating element usually has to connect the wire at the inner center of the heating element and the heating wire wound around the outer surface of the insulating layer by soldering the electrode wire.

However, since the structure of the heating element is generally circular in cross section, when the electrode wires are connected by soldering, there is a problem that the soldering flows out to the outside, and the risk of short circuit and soldering time are very long.

Also, since the electrode wire is connected to the heating element by soldering, there is a problem that the soldering portion is easily short-circuited by an external impact.

In addition, a hot water pipe sealing device for an electric hot water heating device (No. 2014-0005677) has been disclosed.

However, when the heating wire is short-circuited, it is difficult to separate the sealing rod inserted into the connection pipe, and thus it is very difficult to replace the heating wire.

According to a second aspect of the present invention, in the first aspect of the present invention, in the first aspect of the present invention, the first joint member includes: a first sleeve for penetrating and inserting an insulating layer wound on the other side with a heating wire; a first sleeve integrally formed to protrude from the outer peripheral surface of the first sleeve, An auxiliary sleeve through which the electrode line is inserted and an elongated groove formed in the first sleeve so as to allow the first electrode line and the heating wire to be soldered to each other.

The third invention is characterized in that, in the second invention, only one insulating layer without winding the heating wire is exposed to one side of the first sleeve.

The fourth aspect of the present invention is characterized in that, in the first invention, the second joint member is constituted by a second sleeve having a groove formed therein for soldering the wire and the second electrode wire to each other.

A fifth invention is characterized in that, in the first invention, the first joint member and the second joint member are insulated by a shrink tube to be enclosed.

A sixth aspect of the present invention is that, in the first invention, the fastening body further comprises a fixing nut fastened to one side of the first cap nut so as to be easily detachable from the power connection chamber.
