The present invention is a heat conduction pipe, which has the functions of conducting heat energy and radiating heat, and is connected to a hot water storage tank by a connecting part, and the connecting part has a leak-proof function.

The heat pipe is a well-known product, which is used in many fields. It can be seen in machinery manufacturing, textiles, food, home appliances and other related industries peripheral equipment, such as: heating rods for electric heaters, heat dissipation devices for mechanical equipment, and electronic equipment The heat dissipation device of the refrigerator, the heat dissipation part of the refrigerator, etc.

According to the aforementioned heat pipes used in a variety of fields, their styles are naturally quite diverse. Small heat pipes commonly found in home appliances are constructed with pipe fittings, the pipe fittings are provided with fins, and the fins are spirally wound around The pipe body of the pipe fitting can increase the heat conduction area. However, in the method of coiling fins, there will be gaps between the fins and the pipes during the coiling process, so that the fins cannot be closely attached to the pipes. The generation of the gaps causes the heat energy of the pipes to not be well conducted to the fins. . Therefore, some manufacturers will use machines to pressurize the fins, so that the fins are subjected to pressure and deformed to fit tightly on the tube body. However, although the aforementioned method has improved the problem that the fin and the pipe cannot be closely attached, it will be compressed to the pipe and fracturing the aluminum fin when the fin is compressed by the machine (aluminum fin compression process is easy to crack ), so the fins must be made of materials with higher toughness and ductility than aluminum, thus giving up the advantages of lightness, high thermal conductivity, and low price of aluminum fins.

How to develop heat pipes that use aluminum fins, and the fins can still closely fit the pipe fittings, can be said to be a problem that major manufacturers are eager to solve.

The present invention overcomes the conventional problem and uses aluminum heat-conducting aluminum sheet, and the heat-conducting aluminum sheet can be closely attached to the tube body.

In order to achieve the above-mentioned objective, the present invention provides a heat conduction pipe, which includes: a pipe body, which is made of heat-conducting material and has an outer ring surface, and an inner ring surface inside, and the inner ring surface surrounds and forms an inner space of the pipe; A plurality of thermally conductive aluminum sheets, each thermally conductive aluminum sheet has a ring portion and a ring sheet portion in the shape of a ring sheet, each ring portion has a perforation penetrating through two ends, and the ring sheet portion of each thermally conductive aluminum sheet has one end of the corresponding ring portion The outer periphery extends outward, each perforation has an inner wall surface of the hole, the tube body is clamped in the perforation of the plurality of thermally conductive aluminum sheets, and the plurality of thermally conductive aluminum sheets are axially arranged with the tube body as the axis. , And the outer ring surface of the tube body is closely attached to the inner wall surface of each perforated hole, wherein the number and axial distribution range of the plurality of thermally conductive aluminum sheets can be adjusted during processing; and a connecting piece with two ends passing through A through hole, the pipe body part is clamped in the through hole, the connecting piece has a connecting part on the outer periphery, and the pipe body can be connected to a hot water storage tank by the connecting part of the connecting piece.

Here is an example of the connection between the aforementioned connecting piece and the pipe body. The through hole of the connecting piece has an inner hole surface, and the inner hole surface closely adheres to the outer ring surface of the pipe body. This structure reduces heat storage. The probability that the water inside the water tank leaks out from the inner hole surface and the outer ring surface makes the connection part have the effect of preventing leakage.
