Problems solved by technology

At present, the existing condensing heat exchangers for water heaters can be roughly divided into two types according to their structural characteristics. One type is single-channel water inlet and single-channel heat exchange. The heat exchange pipe is coiled or wound within a certain volume range to extend the heat exchange circuit as much as possible. Some heat exchangers are also equipped with heat exchange fins outside the heat exchange pipe to improve heat exchange efficiency. One heat exchange tube, so the hot water output speed is fast and the output temperature is high. However, this type of condensing heat exchanger has a complicated structure and high processing technology requirements. It is necessary to replace the entire heat exchange tube, which is costly and troublesome to maintain
Another type is multi-channel water inlet and multiple heat exchange. This type of condensing heat exchanger has multiple water exchange pipes. Each heat exchange pipe has an independent water inlet and outlet before heat exchange. This type of condensing heat exchanger The structure of the heat exchanger is relatively complicated, and it is mainly used in the central water supply system

Embodiment 2

[0027] Such as Figure 4~5 As shown, this embodiment is a high-efficiency heat exchanger, including three U-shaped heat exchange tubes 7 arranged in parallel and heat collecting fins 2 fixed on the outer surface of the U-shaped heat exchange tubes 7. The U-shaped heat exchange tubes 7 It is placed at an angle of 30° with the vertical direction. A water collection chamber 8 is provided at the end of the branch pipe of the U-shaped heat exchange tube 7. The water collection chamber 8 is a flat cavity structure. A heat insulation layer 9 separates it into two parts that are not connected to each other, the upper cavity is the hot water collecting cavity 5 , and the lower cavity is the cooling water cavity 3 . The hot water collecting chamber 5 is connected with the upper branch pipe of the U-shaped heat exchange tube 7, and the outer side of the hot water collecting chamber 5 is also connected with the hot water outlet port 6, and the cold water collection chamber 3 and the U-sha...

Embodiment 3

[0030] Such as Figure 6 As shown, in this embodiment, compared with Embodiment 1, the cavity-shaped water collection chamber is changed to a thick tube structure, and the two ends of the heat exchange tube 1 are respectively connected to two thick tube-shaped water collection chambers to form a thick tube and a thin tube structure. Besides, other structures and functions are completely consistent with Embodiment 1.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a high-efficiency heat exchanger for water heaters. Background technique [0002] Condensing gas water heaters have gradually become the mainstream of gas water heaters due to their technical advantages such as high efficiency, energy saving, safety and environmental protection. As the core component of condensing gas water heaters, the technology of condensing heat exchangers is also constantly developing. At present, the existing condensing heat exchangers for water heaters can be roughly divided into two types according to their structural characteristics. One type is single-channel water inlet and single-channel heat exchange. The heat exchange pipe is coiled or wound within a certain volume range to extend the heat exchange circuit as much as possible. Some heat exchangers are also equipped with heat exchange fins outside the heat exchange pipe to improve heat exchan...
