Description

Technical Field

[0001] The utility model relates to the technical field of hot water tanks, in particular to a heat recovery water exchange tank. Background Art

[0002] When the stove is in use, its furnace body will dissipate a large amount of heat to the outside, and the exhaust gas generated during the use of the stove will also contain a large amount of heat. This heat generally enters the atmosphere directly, which not only causes energy waste, but also pollutes the atmospheric environment. Therefore, it is necessary to recover this heat. At present, the heat is generally absorbed and utilized through aqueous solution.

[0003] However, the structure of the existing waste heat recovery box is relatively simple, the heat recovery efficiency is low, and the heat recovery effect is not good. In order to solve the above technical problems, the prior art proposes, for example, Chinese patent [application number CN202020055190.8] discloses a waste heat recovery energy-saving water tank, including a recovery box body, a water storage tank and a control system; a heat conductive part and a water collecting cavity are arranged in the recovery box body, and a thermal insulation layer is arranged on the outer surface; the heat conductive part wraps the furnace body, and the heat sink is arranged on the heat conductive part and is located in the water collecting cavity; the first connecting ring and the second connecting ring are located in the water collecting cavity; the heat conducting pipe is connected to the first connecting ring and the second connecting ring is ... A connecting ring and a second connecting ring; although the patent can allow the hot exhaust gas to enter the first connecting ring through the flue gas inlet pipe and evenly disperse it into each heat transfer tube, the aqueous solution in the water collecting chamber absorbs the heat in the hot exhaust gas, and can effectively absorb the heat emitted from the periphery of the furnace body and the heat in the hot exhaust gas, with good heat recovery effect and high heat recovery efficiency; however, the above patent has certain defects during use. For example, the heat transfer tube in the above patent is fixedly arranged, which will cause the water in the water tank to be heated unevenly, thereby increasing the heating time and reducing the heat exchange efficiency.
