Abstract
The invention discloses a parallel-row coiled pipe heat exchanger. The parallel-row coiled pipe heat exchanger comprises a frame, an input main pipe, plate grids, a connection pipe, a return main pipe, an inner-channel heat exchange pipe and an outer-channel heat exchange pipe. The inner-channel heat exchange pipe is coaxially and spirally coiled by 3-6 circles, the outer-channel heat exchange pipe is coaxially and spirally coiled by 2-3 circles, and the inner-channel heat exchange pipe and the outer-channel heat exchange pipe form a heat exchange unit on the same layer surface. 10-20 heat exchange units connected by the connection pipe are installed in the frame, and each two units are spaced and located by the corresponding plate grid. The input main pipe and the return main pipe are both three-way pipelines; and two outlets of the input main pipe are abutted with the connection pipe which is already connected with the inner-channel heat exchange pipe and the outer-channel heat exchange pipe respectively, and the return main pipe is abutted with the connection pipe which is already connected with the inner-channel heat exchange pipe and the outer-channel heat exchange pipe respectively by two outlets, thus an annular-flow heat exchange structure for uniform injection and discharge of a heat exchange medium is formed. The parallel-row coiled pipe heat exchanger disclosed by the invention is short in heat radiation distance, fast in heat exchange and high in efficiency; and moreover, the heat exchanger with a coiled pipe structure is short in axial dimensions, and especially suitable for matching with a heat treatment furnace.
