detailed description

The present invention will be further described below.

Embodiment: Referring to Fig. 1 to Fig. 5, a double-channel wall-mounted heat exchanger includes two water chambers 1, and several parallel heat exchange tubes 2 are arranged between the two water chambers 1, and the heat exchange The number of tubes 2 is 4-8. In this embodiment, 6 tubes are taken as an example. The two water chambers 1 are communicated through the heat exchange tubes 2. The heat exchange tubes 2 are all provided with inner tubes 3, and the inner tubes 3 There is a gap between the inner wall of the heat exchange tube 2, and the gap is a heating water channel, and the adjacent inner tubes 3 are connected to form a serpentine tubular shape through a connecting elbow 4, and a domestic water channel is formed inside the inner tube 3 , the inner pipe 3 is provided with a domestic water inlet 6 and a domestic water outlet 7, and the water chamber 1 is provided with a heating water inlet 8 and a heating water outlet 9. The inner tube 3 is provided with a spoiler spring 5, the spoiler spring 5 conducts heat quickly, which is beneficial to improve the thermal efficiency in the tube, reduces the noise generated by the water flow, and forms turbulent flow to improve the heat exchange efficiency of the water flow. The spoiler spring 5 is made of stainless steel Cheng, no rust, long service life and will not affect water quality.

The cross-section of the heat exchange tube 2 is oval, and the inner tube 3 is a circular tube with a circular cross-section. The inner tube 3 is used as a channel for daily use. The diameter of the inner tube 3 is the same as the short axis length of the heat exchange tube 2. The inner tube 3 is welded in the heat exchange tube 2. The welding method makes the inner tube 3 is fixed in the heat exchange tube 2 and is not easy to loosen, will not collide to generate noise, has a long service life, and has a good heat conduction effect to promote heat exchange between the inner tube 3 and the heat exchange tube 2, and is in contact with the heating medium in the heating water channel Large area and good heat exchange effect.
