Problems solved by technology

Heat exchangers include traditional casing heat exchangers, which have high thermal efficiency but are difficult to process and clean; the other is an assembled spiral casing heat exchanger, which consists of a pair of spiral shells A spiral channel with a circular cross-section is formed by bolt connection and sealing. The channel has a built-in core tube, and a copper tube is wound in parallel on the core tube. The inside of the copper tube is a cleaning medium. High-temperature medium with poor temperature, this kind of heat exchanger is easy to process and easy to clean, but the structure is cumbersome and inconvenient to install and maintain

Embodiment Construction

[0012] Such as figure 1 , 2 , 3, the heat exchanger is mainly composed of a jacket 1 and a bellows 2. The bellows 2 are arranged spirally and annularly in the jacket 1 to form the main body of the heat exchanger as a whole. The two ends of the bellows 2 are installed with clean water through the connector 8. Water inlet and outlet 3,4, waste water inlet and outlet 5,6 are installed through connector 8 on the overcoat 1.

[0013] The inside of the bellows 2 is clean tap water, and the channel formed by the outer wall of the bellows 2 and the inner wall of the jacket 1 is waste hot water with poor cleanliness, and the two media form convection to fully exchange heat. When the low-temperature tap water flows from the water inlet 3 to the water outlet 4 at the other end through the bellows 2, the high-temperature waste water flows from the waste water inlet 6 to the waste water outlet 5 at the other end through the channel formed by the outer wall of the bellows 2 and the inner w...

Abstract

The spiral bellows type heat exchanger consists of mainly an outer jacket and a spiral bellows arranged inside the outer jacket. The bellows has clear water inlet and outlet on its two ends, and the outer jacket has waste water inlet and outlet on its two ends. The spiral bellows type heat exchanger has high heat efficiency, simple structure, and easy installation and maintenance.

Description

Technical field [0001] The invention relates to a heat exchanger, in particular to a spiral bellows heat exchanger. Background technique [0002] The waste hot water after use by gas-fired, electric or solar showers still has a certain amount of heat energy. If it can be fully utilized, it will increase the heat utilization rate and reduce the use cost of the shower. At present, heat exchangers are used to realize the utilization of waste heat. Heat exchangers include traditional casing heat exchangers, which have high thermal efficiency but are difficult to process and clean; the other is an assembled spiral casing heat exchanger, which consists of a pair of spiral shells A spiral channel with a circular cross-section is formed by bolt connection and sealing. The channel has a built-in core tube, and a copper tube is wound in parallel on the core tube. The inside of the copper tube is a cleaning medium. For high-temperature medium with poor temperature, this kind of heat e...
