The utility model a special heat-pipe negative-pressure combustion combined device for a pulse combustion heating furnace and belongs to heating furnace devices. The special heat-pipe negative-pressure combustion combined device consists of a box body, a combustion chamber cylinder body, tail pipes and heat pipes, wherein one end of the combustion chamber cylinder body penetrates one side wall of the box body and is placed in the box body; more than one group of tail pipes are arranged at the end part of the combustion chamber cylinder body, which is placed in the box body, and penetrate the other side wall of the box body; more than one heat pipes penetrating the box wall are arranged on the box body perpendicular to the combustion chamber cylinder body. The special heat-pipe negative-pressure combustion combined device for the pulse combustion heating furnace has the advantages that the negative-pressure combustion combined device consists of the box body and the heat pipes, the box body adopts a unique structure endowing the box body with the telescopic property, heat transfer oil is filled in part of the box body, and the residual space is pumped to be in the negative-pressure state, so that deformation of the box body, caused by temperature rise of the heat transfer oil, is effectively relieved; the heat pipes are welded on the box body to perform a heat dissipation function.
