Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

In the examples, as shown in FIGS. 1-4: the utility model provides a graphite composite insulation board, includes heat accumulation surface course 4, heat exchange tube 1, heat-conducting layer and heat preservation bottom plate 2, the heat-conducting layer is upper and lower two-layer graphite membrane 3, heat exchange tube 1 sets up two-layerly from top to bottom between the graphite membrane 3, be equipped with respectively on heat accumulation surface course 4 and the heat preservation bottom plate 2 with the

recess

401, 201 that the heat exchange tube 1 suited. In the embodiment, the graphite film 3 is used as the heat conduction layer, and the graphite film 3 has good heat conduction and heat distribution performance and can conduct heat and distribute heat along the plane direction of the film, so that the heat brought by the heat exchange tube 1 can be quickly and uniformly distributed to the whole heat insulation board and transferred to the heat storage surface layer 4, and the heat is slowly radiated indoors through the heat storage surface layer 4, so that the indoor temperature is kept stable and comfortable; and the graphite film 3 has good flexibility, can be attached to any uneven surface, is easy to cut and adhere, and is convenient to process and operate. In the embodiment, the heat exchange tube 1 is a metal tube or a polyethylene cross-linked tube, the tube diameter is 10-15mm, and the heat exchange tube is U-shaped, S-shaped or M-shaped; because the graphite film 3 is very thin, the thickness is usually only 0.03-2mm, the flexibility is good, and
