In order to realize the utilization of the waste heat of the flue gas and improve the energy utilization rate, the waste heat needs to be recovered. The traditional heat exchanger mainly adopts a tube-plate structure, and has the problems of large volume, large smoke resistance, easy low-temperature corrosion generation, low commissioning rate and the like in the waste heat recovery process. The heat pipe type heat exchanger can well solve the problems, the lower part of the heat pipe type heat exchanger is a flue, the upper part of the heat pipe type heat exchanger is a water tank, a steam drum or a water sleeve, and the middle of the heat pipe type heat exchanger is separated by a partition plate. The flue gas passes through the flue from left to right, and the cooling water flow direction and the flue gas flow direction form a counter current, so that the heat exchange average temperature is improved, and the heat exchange amount is increased. When the heat pipe waste heat recoverer works, smoke flows through a flue of the heat pipe waste heat recoverer to wash the lower end of the heat pipe, working medium on the lower portion in the heat pipe absorbs heat and then changes from liquid state to gas state, enters the heat release end on the upper portion from the heat absorption end on the lower portion, is cooled by cooling water on the outer side of the upper portion of the heat pipe, condenses into liquid state, and flows into the heat absorption end again along the pipe wall to form circulation, and heat absorption and heat release are achieved continuously. In the prior art, the fins of the heat pipe are welded on the outer wall of the heat pipe body, the flow resistance of the smoke side at the heat absorption end is large, and the heat exchange coefficient of the gas side is low.

According to the further technical scheme, one end, far away from the heat pipe body, of each spiral fin is the top, and the thickness of the top of each spiral fin is smaller than that of the root of each spiral fin.
According to a further technical scheme, the cross section of the spiral fin is trapezoidal.
The utility model has the advantages that:
(1) The heat pipe body and the spiral fins of the heat absorption end of the utility model are formed by integral rolling, thus making up the weak point of low heat exchange coefficient of the gas side, meanwhile, the flow resistance of the smoke side is relatively small, and the heat transfer efficiency is high;
(2) The heat pipe body and the spiral fins are manufactured by a rolling process, so that the integral fin thread pitch of the heat absorption end of a single heat pipe can be adjusted in the rolling process, the transmission power of a heat pipe element is adjusted, and the working wall temperature of the heat pipe is controlled within a certain range under the acid dew corrosion using environment by adjusting the heat transfer area ratio of the cold side and the hot side of the heat pipe, so that the working wall temperature of the heat pipe is increased to be higher than the dew point temperature, and the acid dew point corrosion is prevented;
(3) The roots of the spiral fins are wide, the tops of the spiral fins are narrow, and the spiral fins are of an inclined structure, so that dust accumulation can be effectively avoided.
