The pipes and water inlet pipes in the heat-absorbing sheet can obtain higher thermal efficiency; the structure is simple, the manufacture is easy, and the cost is low.

Description

The utility model relates to a water heater tank.

At present, there is a known water heater water tank as shown in Figure 1. In the figure, 3 is the water tank, 40 is the heating plate, 5 is the water pipe, 51, 52 are the two ends of the water pipe 5, and the water pipe 5 goes around the plate and reaches the heating plate 40. , because the water pipe 5 is in contact with the water tank 3, the contact surface is very narrow, resulting in poor heat transfer efficiency; and the pipeline is entangled and the two ends of the water pipe 51, 52 extend out of the water tank too long, which affects packaging and transportation, and the water pipe The ends are easily damaged. The water heater water tank of application number 91225029.1 adopts an integrally formed plate body, and the water tank shell has a heating water flow path that surrounds the water tank and spirals upwards. Although the thermal efficiency is good, it is difficult to manufacture and the cost is high.

The purpose of this utility model is to provide a water heater water tank with a heating water flow path in an upper and lower meandering interlayer space composed of two plates, which has a simple structure and high thermal efficiency.

The purpose of this utility model is achieved in this way: it is composed of connecting pipes, pipelines, water inlet pipes, outlet pipes, heating sheets and a shell. The water tank shell is made of two plates to form a sandwich. A space winding up and down around the water tank is formed, and the two ends of the space are respectively connected to the pipeline in the heat-absorbing sheet and the water inlet pipe. The water tank housing is bent into a rectangle. One plate body is a groove plate 20, and the groove plate 20 has convex grooves; the other plate body is an inner casing 22, and the inner casing 22 has grooves corresponding to the convex grooves, and the groove plate 20 is closely fitted to the inner casing 22 Above, an interlayer space is formed, and the interlayer space forms a heating water flow path 21 .

Due to the adoption of the above scheme, the flow path of the water heater tank is an interlayer space formed by two plates, which has a large contact area with the water tank and can obtain better heat transfer effect; it is not necessary to use pipe fitting materials in manufacturing, saving the need for processing bends Winding and other processes, so it is easy to manufacture and reduce costs; the surface of the water tank is flat, the length of the aqueduct at both ends is flush with the water tank, and the whole is a square cube, which is conducive to packaging and transportation.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a reference diagram of a known water heater tank.

Fig. 2 is a perspective view of a known water heater tank.

Fig. 3 is a structural diagram of an embodiment of the utility model.

Fig. 4 is a schematic diagram of an embodiment of the utility model.

Fig. 5 is a side view of the utility model embodiment.

In the figure: 3. Water tank, 31. Connecting pipe, 32. Pipeline, 33. Water inlet pipe, 34. Outlet pipe, 22. Inner shell, 5. Water pipe, 51, 52. Both ends of water pipe, 40. Heating sheet, 20. Slot plate, 21. Mezzanine space.

Referring to Figures 3 to 5: the utility model is composed of two boards, one of which is a slot plate 20, and the other is an inner casing 22. The slotted plate 20 and the upper and lower vertical meanders surround the interlayer space of the water tank, that is, the flow path 21 and the inner casing 22 . The groove plate 20 is tightly attached to the inner casing 22 by welding, and a sandwich space flow path 21 is formed by the groove on the inner casing or the convex groove on the groove plate 20. The flow path 21 is vertical and meanders up and down. around the tank. The pipe fitting 31 connects the upper end of the interlayer space 21 to the pipeline 32 in the heat-absorbing sheet 40, the lower end of the interlayer space 21 is connected to the water inlet pipe 33, and the pipeline end of the heat-absorbing sheet 40 forms the outlet pipe 34; the water inlet pipe 33 and the outlet pipe 34 The length is flush with the bottom surface of the water tank shell, so that the shape of this product is a rectangle without sharp protrusions. The two long tubes 33, 34 do not protrude and are easy to pack and transport.

When in use, the water inlet pipe 33 is connected to the water source pipeline, and the outlet pipe 34 is connected to the hot water supply pipeline, then the cold water is introduced into the interlayer space 21 of the groove plate 20 by the water inlet pipe 33, and reaches the heat absorbing fin 40 around the inner casing 22 of the water tank. , after being heated into hot water, it is supplied to the hot water pipeline system by the outlet pipe 34 for use.
