Embodiment 1

[0024] The sleeve-type joint-mounted high-efficiency dual-purpose water tank includes a shell and a water bladder, and the structure is as follows figure 1 As shown, the top structure of the water tank is as follows figure 2As shown, the water bladder is made of an upper end cover 9, a lower end cover 10 and a double-layer metal tube. The upper end cover 9 is provided with a hot water outlet 7, and the lower end cover is provided with a cold water inlet 8. The double-layer metal tube consists of an outer tube 2 and an inner tube. The upper end of the inner tube 1 is fixed with the upper end cover 9, the lower end of the inner tube 1 is fixed with the lower end cover 10, the outer tube 2 is set outside the inner tube 1, and the upper end of the outer tube 2 is connected with the inner tube 1. The upper ends are fixed together, the lower end of the outer tube 2 and the lower end of the inner tube 1 are fixed together, and there is a gap of 0.04-0.6 mm between the inner wall of ...

Embodiment 2

[0035] The sleeve-type joint-mounted high-efficiency dual-purpose water tank is the same as that of Embodiment 1, the difference is that: there are 10 water bladders in the sleeve-type joint-mounted high-efficiency dual-purpose water tank, the middle part of the shell is an outer cover with a glass plate on one side, and the other three sides It is made of opaque material, and the side of the outer tube opposite to the glass plate is provided with a black coating. A partition is used to divide the middle part of the shell into two parts. The partition and the center of each water bladder are on the same plane, between the outer tube and the opaque side The gap is filled with insulating material, and the outer surface of the outer tube opposite to the transparent side is coated with a black coating.

[0036] The heat exchange area is 0.076m×3.14m×1.8m×10=4.3m 2 , volume ratio V=(S1-S2) H N (where S1 is the inner circle area of ​​the outer tube, S2 is the outer circle area of ​​...

Embodiment 3

[0040] The water tank structure of the sleeve-type joint-mounted high-efficiency dual-use water tank is the same as that of Example 1, except that the outer tube adopts a general-purpose tensile aluminum alloy tube with an inner diameter of 114.5mm and a wall thickness of 1.8mm, and the length is 1.8m. The surface is coated with black coating, and the inner tube is made of 304 stainless steel tube with an outer diameter of 114.4mm and a wall thickness of 1.6mm.

[0041] The pressure of the outer pipe is (2×1.8×160Mpa) / 114.5=5.03Mpa, the pressure of the inner pipe is (2×1.6×380 / 2Mpa) / 114.4=5.3Mpa, when the tap water pressure is 3kg, the maximum pressure at the end Only (11.4 / 2) 2 ×π×3=306kg.

[0042] There are 6 water tanks in the sleeve-type joint-mounted high-efficiency dual-use water tank, which are fixed on the footing bracket in a single row. The total heat exchange area of ​​the water tanks is 0.114m×3.14m×1.8m×6 = 3.87m 2 , volume ratio V=(S1-S2) H N (where S1 is the i...

Abstract

The invention relates to a telescopic connected high-efficiency dual-purpose water tank which comprises a shell and a water chamber assembled in the shell and is characterized in that the water chamber comprises an upper end cover, a lower end cover and a dual-layer metallic pipe between the upper end cover and the lower end cover; the dual-layer metallic pipe comprises an outer pipe and an inner pipe; a gap of 0.04-0.6mm exists between the inner wall of the outer pipe and the outer wall of the inner pipe and is used as a refrigerant heat exchange channel; a refrigerant inlet is arranged at the upper part of the outer pipe, and a refrigerant outlet is arranged at the lower part of the outer pipe; the refrigerant inlet and the refrigerant outlet are communicated with the refrigerant heat exchange channel; and the inner part of the water chamber is respectively communicated with a water outlet pipeline and a water inlet pipeline through a hot water outlet and a cold water inlet. The telescopic connected high-efficiency dual-purpose water tank of the invention has the advantages of large heat exchange area, high utilization rate of heat exchange of refrigerants, high efficiency of matching small-power units, long service life and the like, can be connected with a large-power air conditioner to be used as a low-temperature high-efficiency heating source, and is suitable for various environments.

Description

technical field [0001] The invention relates to a heat exchange tank, in particular to a casing-type combined high-efficiency dual water tank. Background technique [0002] The current heat pump water tank basically adopts a barrel structure, with a condensing coil inside or a condensing coil coiled outside the water tank. There is also a patent for a heat pump water tank with a lining (200510015722.5). The diameter of the water tank is greater than 400mm, and the water tank bears The pressure calculation expression is: P=2SR / D, and the end cover pressure expression is: P=(D / 2) 2 ×π×G, (where P-can withstand pressure; S-nominal wall thickness of steel pipe; R-allowable stress of the material; D-nominal diameter of steel pipe; G is working pressure), it can be known from the calculation expression that the barrel water tank The pressure of the water tank is inversely proportional to the diameter, and the large-diameter water tank can only use the coil welding technology, the...
