In the practical application process, high temperature flue gas will be from spiral helicine body inner circle outdiffusion to and realize the heat exchange with body contact process, be subject to installation space's narrow and small, the body coil inside and outside the number of turns more then can cause the great condition of whole weight, water resistance, and the body coil inside and outside the number of turns less then can lead to heat exchange area less, heat exchange rate is limited, can't effectively carry out the heat exchange. Therefore, how to reasonably design the winding structure of the tube body has a crucial influence on the heat exchange efficiency of the whole equipment.

The utility model content is as follows:

the utility model aims to provide a disc-shaped heat exchanger which is reasonable in design, small in size, small in water resistance and large in heat exchange area.

The utility model is realized by the following steps:

a disc-shaped heat exchanger comprises a heat exchange tube body formed by coiling a heat exchange tube, wherein the heat exchange tube body comprises an outer heat exchange tube section, an inner heat exchange tube section and a transition tube section communicated with the outer heat exchange tube section and the inner heat exchange tube section, the outer heat exchange tube section and the inner heat exchange tube section are both annularly wound into a spiral structure, the outer heat exchange tube section is a corrugated tube with a corrugated wall surface along the axial direction of the corrugated tube, and the inner heat exchange tube section is a light tube and is sleeved with heat absorbing sheets at intervals along the axial direction of the light tube.

In the disc heat exchanger, the outer port of the outer heat exchange tube section is a water inlet port, the inner port is communicated with the inner port of the inner heat exchange tube section through the transition tube section, and the outer port of the inner heat exchange tube section is a water outlet port.

In the disc heat exchanger, the outer ends of the outer heat exchange tube section and the inner heat exchange tube section extend outwards to form a connecting light pipe section for communicating with external equipment.
