Description
[ field of technology ]
The utility model relates to the technical field of heat pipe low-temperature economizers, in particular to the technical field of heat pipes of heat exchangers which are vertically arranged and are not easy to accumulate ash.
[ background Art ]
In recent years, a water sleeve heat pipe heat exchanger is beginning to be applied to a low-temperature economizer, because the heat pipes are divided into a hot end and a cold end, the hot end of the heat pipe low-temperature economizer is arranged on the inner side of a flue, the cold end of the heat pipe is arranged on the outer side of the flue, the cold end of each heat pipe is provided with a water sleeve, and then the water sleeve is connected in series with a small-diameter pipe so as to achieve circulation of cooling water, thereby greatly avoiding the leakage problem of the traditional low-temperature economizer and enabling the heat pipe low-temperature economizer to continuously operate for a long time. The hot end fins are H-shaped fins, spiral fins, integrally rolled fins, saw-tooth fins and the like. Spiral fins and zigzag fins are mainly used in the vertically arranged heat pipe exchanger.
Due to the structural characteristics of the heat pipe heat exchanger, the vertical arrangement is a main form of the heat pipe heat exchanger. Because traditional fin is perpendicular to base pipe surface mounting, so when the heat pipe erects the installation, the fin plane of originally perpendicular to base pipe surface just becomes the direction of horizontal plane, and traditional structure in long-term operation, the dust in the flue gas can accumulate on the plane of fin, especially leeward face, forms the deposition, hardly clears away, influences heat exchange efficiency. Accumulated ash becomes more serious and forms a bridge, so that the resistance of equipment is greatly increased.
[ utility model ]
The utility model aims to solve the problems in the prior art, and provides a heat pipe of a heat exchanger which is arranged vertically and is not easy to accumulate ash, so that the heat exchange area is increased.
In order to achieve the above purpose, the utility model provides a heat pipe of a heat exchanger, which is arranged vertically and is not easy to accumulate ash, and the heat pipe comprises a base pipe, wherein the base pipe is divided into an evaporation section, a condensation section and an insulation section positioned between the evaporation section and the condensation section along the length direction of the base pipe, fins are arranged on the evaporation section, the fins are in an inclined state with the outer side low and the inner side high, and sawteeth are arranged on the fins on the lee surface of the evaporation section.
Preferably, the fins have a spiral structure with a lower outer edge and a higher inner edge.
Preferably, the included angle a between the upper surface of the fin and the horizontal plane is 15-60 degrees.
Preferably, the included angle a is 60 °.
Preferably, the inner edges of the fins are welded with the evaporation section.
Preferably, the saw teeth on the fins are arranged in a one-to-one correspondence from top to bottom.
The utility model has the beneficial effects that: according to the utility model, the fins are in an inclined state with the outer side low and the inner side high, the fins on the leeward side of the evaporation section are provided with the saw teeth, so that ash deposition is easier to occur on the leeward side of the traditional vertical heat pipe compared with the windward side, and the saw teeth are arranged on the leeward side, so that ash deposition in leeward area can be further prevented, and compared with the prior art, the heat exchange area can be increased.
The features and advantages of the present utility model will be described in detail by way of example with reference to the accompanying drawings.
