Detailed Description

The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the coupling/connection relationships mentioned herein do not mean that the components are directly connected, but mean that a better coupling structure can be formed by adding or reducing coupling accessories according to specific implementation conditions. All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.

The first embodiment is as follows: referring to fig. 1-4, a heat storage and exchange device for a gas appliance comprises a heat preservation shell 1, a heat exchange core 2 is arranged in the heat preservation shell 1, a phase-change heat storage material 3 is filled between the heat exchange core 2 and the heat preservation shell 1, the heat exchange core 2 comprises a water collection box 21 and a water diversion box 22, a water outlet nozzle 23 is arranged on the water collection box 21, a water inlet nozzle 24 is arranged on the water diversion box 22, the water outlet nozzle 23 and the water inlet nozzle 24 both penetrate out of the heat preservation shell 1, and the water outlet nozzle, the water inlet nozzle and the heat preservation shell are in sealing connection. A plurality of heat exchange tubes 25 with oval cross sections are arranged between the water collecting box 21 and the water dividing box 22, and the plurality of heat exchange tubes 25 are uniformly arranged between the water collecting box 21 and the water dividing box 22 at intervals. The water collecting box 21, the water dividing box 22, the water inlet nozzle 24 and the water outlet nozzle 25 are all metal components and are connected together in a welding mode, and the heat storage material 3 is coated on the outer surface of the heat exchange tube 25. The heat storage material is an expanded graphite/paraffin composite material. The heat preservation shell 1 comprises an outer shell 11 and an inner shell 12, wherein the inner shell and the outer shell are connected through a support part 13, vacuum is pumped between the outer shell and the inner shell, and meanwhile, the inner surface of the inner shell is coated with heat-insulating anti-corrosion paint. And the heat storage material is filled in the inner casing.

In the whole heat exchange process, the heat storage material is subjected to two stages: 1) a heat storage phase. I.e. to store excess heat during peak periods. 2) And (4) a heat release stage. Firstly, a heat storage stage: hot water of the gas water heater enters the heat exchange device from the water inlet nozzle, then enters the heat exchange tube after passing through the water diversion box, then exchanges heat with a heat storage material outside the heat exchange tube, the heat storage material stores redundant heat, and then the water flows into the water collection box and flows out from the water outlet nozzle.

Then, when the water temperature is lowered and the water flows through the heat exchange pipe, the heat storage material is heat-exchanged with the water in the heat exchange pipe to release the stored heat to the cold water in the heat exchange pipe.

That is, heat is released by the heat storage material during use to supply heat, hot water, or the like. The heat storage and release stages are carried out in a circulating manner, so that zero cold water of the gas appliance bathroom outlet water can be realized by utilizing the heat storage material, and the energy is saved.

In the second embodiment, besides the evacuation, heat insulation materials such as aluminum silicate fiber, pearl wool, EVA and the like can be filled between the outer shell and the inner shell. The rest of the structure is the same as the first embodiment.

The heat exchange tube can also be a round tube or a spiral flat tube.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
