Improved solar heat exchange water storage tank

Abstract

The invention discloses an improved solar heat exchange water storage tank, which relates to a heat exchange water storage tank and solves the technical problem of flashover or sealing-off in the machining or transportation of the conventional water storage tank. The improved solar heat exchange water storage tank comprises a hollow tank body, and is characterized in that: the upper and lower ends of the tank body are provided with an upper end cover and a lower end cover respectively; the upper and lower end covers are inwards sunken and matched with the upper and lower surfaces of the tank body to form an upper cavity and a lower cavity respectively; the upper and lower cavities are communicated with each other through at least one heat exchange tube passing through the tank body; and each of the upper and lower end covers is provided with a connecting pipe orifice communicated with own cavity. In the improved solar heat exchange water storage tank, the arrangement of a fluid reservoir is canceled, and a heat transfer medium is diffused into vertical fixed heat exchange tubes which are highly stationary, thereby avoiding potential safety hazards such as the flashover, sealing-off and the like which may be caused in mounting or transportation in the tank body; and the improved solar heat exchange water storage tank is convenient to mount and low in cost.

Description

technical field [0001] The invention relates to a heat exchange water storage tank, in particular to an improved solar heat exchange water storage tank. Background technique [0002] Existing a kind of solar heat exchange water storage tank, as figure 1 As shown, a liquid storage tank 9 for storing heat transfer medium is installed inside the box body 1, and the liquid storage tank 9 is supported by a support rod 11 connected to the bottom of the box body 1, and during transportation, there is no water in the box body 1 , and the liquid storage tank 9 is full of heat transfer medium, which is unbalanced in weight and weight, so the stability is poor, and it is easy to shift or even fall due to vibration during transportation, installation and use, and a heat transfer medium leakage accident occurs; the liquid storage tank 9 is in contact with the outside world. The solar heat collector is connected so that the heat transfer medium can circulate. The liquid storage tank 9...

Problems solved by technology

[0002] There is a solar heat exchange water storage tank, such as Figure 1, a liquid storage tank 9 for storing heat transfer medium is installed inside the box body 1, and the liquid storage tank 9 is connected to the support rod at the bottom of the box body 1 11 is supported, and during transportation, there is no water in the box body 1, and the liquid storage tank 9 is filled with heat transfer medium, which is unbalanced in weight and weight, so the stability is poor, and it is easy to shift or even fall due to vibration during transportation, installation and use , a heat transfer medium leakage accident occurs; the liquid storage tank 9 communicates with the external solar heat collector so that the heat transfer medium can circulate, and the liquid storage tank 9 is also connected with a hollow heat exchange tube 6 surrounding its periphery, and the heat exchange tube 6 are set on the bracket 10 welded with the inner wall of the water storage tank. When the parts of the water storage tank such as the bracket 10 are welded, the gap between the heat exchange tube 6, the liquid storage tank 9 and the bracket 10 is likely to cause the heat exchange tube 6 , the liquid storage tank 9 and the support 10 meet with each other, and a high-voltage flashover occurs instantaneously, causing the heat exchange tube 6 or the liquid storage tank 9 to become thinner (or even breakdown, which directly leads to the leakage of the heat transfer medium). In the daily use of the finished water storage tank, the liquid storage tank 9 and the heat exchange tube 6 are affected by the flow pressure of the heat transfer medium and the thermal expansion and contraction, the thinning part of the tube wall will leak, and the heat transfer medium will Mixed into the water in the water tank, and the heat transfer medium generally contains chemical substances harmful to the human body, such as ethylene glycol, diethylene glycol and industrial alcohol, etc. Once the human body touches or ingests the polluted water source, it will cause poisoning; and At the same time, the welding is all completed inside the water storage tank, and the operation is cumbersome; since the liquid storage tank 9 is built in the box body 1, the effective liquid storage space of the box body 1 is occupied, and the volume and the use area of ​​the box body are increased; and during processing At this time, since the liquid storage tank 9 is located at one end of the box body 1, the heat exchange area is limited, and the water temperature is inconsistent
