Heat pump water pipe boiler

The invention relates to a heat pump water pipe boiler. The heat pump water pipe boiler comprises a hearth, and is characterized in that a traditional fire grate in the hearth is changed into a heat pump pipeline, and the heat pump pipeline is in a horizontal state; the heat pump pipeline comprises a pipe shell and a spiral sleeve structure axially formed on the inner wall of the pipe shell, an inner flow guide cavity is formed in the spiral sleeve structure, and an outer flow guide cavity is formed between the outer portion of the spiral sleeve structure and the pipe shell; and a flat hole isformed in the spiral sleeve structure and used for communicating the inner flow guide cavity with the outer flow guide cavity. Compared with a traditional boiler, the improved structure only involvesthe fire grate in the hearth, transformation is very convenient and easy to achieve, and the transformation cost is also very low. 本发明涉及一种热力泵水管锅炉，包括炉膛，其特征在于，将所述炉膛内传统的炉排改为热力泵管路，且所述热力泵管路呈水平关态；所述热力泵管路包括管壳以及轴向形成于管壳内壁的螺旋套结构，所述螺旋套结
