Abstract

The utility model relates to an eccentric heating pipe which belongs to the heat transfer member. The eccentric sleeve is composed of an inner straight tube and an outer straight tube. The end of the sandwich of the sleeve is sealed to make the sandwich between two-layer tubes form a sealed cavity. The inorganic heat conducting medium is filled in the sandwich. The inner tube is a through tube. The hot fluid flows through the inner tube and transfers the heat to the heat conducting medium and the heat is transferred to the cooling fluid out of the sleeve by the heat conducting medium. The eccentric heating pipe has simple process, low cost and high thermal efficiency. The eccentric heating pipe can be widely popularized in various fields.

Description

Eccentric heating pipe

The utility model belongs to heat transfer element.

Known heat pipe form is to make the tube core that shell, inner wall of tube shell tightly adhere to porous capillary structure by the metal shell of sealing at present, soaking into the heat transfer working fluid in the tube core, general water, oil, ethanol and other organic compounds of adopting, the thermal conductivity of this heat pipe is higher, but complex structure, manufacture craft conditional request height and cost are expensive, make to promote and use to be subjected to certain limitation.

The purpose of this utility model is intended to propose a kind of technical scheme of novel heat-conduction component, and more above-mentioned heat pipe structure is simple, cost is low and heat transfer efficiency is high, applicable to many technical fields, is convenient to apply on a large scale.

The technical solution of the utility model is formed decentralized casing by inside and outside two straight tubes, and interior straight tube is a siphunculus, the sealing of decentralized casing interlayer end, and the straight tube outer wall forms closed cavity with the gap of outer straight tube inwall in making, and liquid inorganic heat-conducting medium is housed in the closed cavity.

This heat-pipe elements is horizontal positioned in use, and hot fluid passes from interior pipe tube chamber, by the heat-conducting medium in the closed cavity heat is transferred in the cold fluid of the heat pipe outside of flowing through, and its temperature is raise, and perhaps the cold and hot fluid passage is opposite.

For making heat-transfer effect better, with the clearance control between sleeve bottom two tube walls in the scope of 2mm-10mm.Two end faces of inside and outside straight tube can be in the same plane, also can be as required with the outstanding 30-200mm of the external mutually straight tube end face of internal straight tube end face.

The utility model manufacture craft is simple, and is with low cost, and heat transfer efficiency can reach more than 90%.

Embodiment and description of drawings:

Fig. 1 is the structural representation of embodiment 1.

Straight tube in the 1-, the outer straight tube of 2-, 3-closed cavity.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the B-B cutaway view of Fig. 2.

The two end faces of the inside and outside straight tube of embodiment 1 is on a plane, and with its sealing.

Fig. 4 is the front view of embodiment 2.

Fig. 5 is the left view of Fig. 4.

The internal straight tube end face of embodiment 2 outer straight tube end face is given prominence to 50mm, with the both ends of the surface of outer straight tube respectively with the outer wall welded seal of interior straight tube.

The utility model is used for the waste-heat recovery device of various types and other heat transfer, heat-exchange device, and energy-saving effect is remarkable.
