In order to solve the above technical problems, we have proposed a kind of heat pipe preheater, the air preheater structure is tight
Gather, small volume, heat transfer efficiency is higher and corrosion-resistant, stifled ash is not easily caused, service life is longer.
To reach above-mentioned purpose, technical scheme is as follows：A kind of heat pipe preheater, including casing, every
Plate, a plurality of heat pipes, heat transfer medium and shoot door；The dividing plate is erected in the casing, and the casing is divided into a left side
Right two cavitys, the left chamber body is to offer air outlet slit at the top of condensation chamber, the condensation chamber, and its bottom offers air and entered
Mouthful, the right chamber body is to offer smoke inlet at the top of evaporation cavity, the evaporation cavity, and its bottom offers exhanst gas outlet, described
Multiple mounting holes, a plurality of heat pipes point are offered on left side wall top, right side wall bottom and the dividing plate of casing respectively
Not other from left to right being fixedly installed in the mounting hole diagonally downward, the heat transfer medium is arranged in the heat pipe, described
The left side wall top and right side wall bottom of casing are separately installed with the shoot door.
It is preferred that, it is wound with fin on the heat pipe.Heat transfer area can so be increased, heat transfer efficiency is improved.
It is preferred that, the junction of the heat pipe and the dividing plate is provided with sealing device.
It is preferred that, left and right ends portion is respectively arranged with linkage section, the linkage section and is provided with external screw thread on the heat pipe,
It is provided with internal thread in mounting hole in the casing left and right sidewall, heat pipe left and right ends portion is respectively with the casing or so
Mounting hole threaded connection on the wall of side.
By above-mentioned technical proposal, the present invention is passed through by flue gas from the evaporation cavity, transfers heat to the heat pipe
The interior heat transfer medium, the heat transfer medium evaporation, subsequently into the condensation chamber, is transferred heat to by the condensation
The air of intracavitary, then the heat transfer medium liquefaction, the evaporation cavity is flowed back to along the heat pipe inner wall；The air preheater knot
Structure is simple, and compact conformation, greatlys save dimensional footprint, and the air preheater air preheater is provided with shoot door,
Stifled ash can be often cleared up, heat transfer efficiency is higher, and single heat pipe damages and does not interfere with using effect, service life is longer.
