Coil type heat exchanger

Abstract

The invention provides a coil type heat exchanger. The coil type heat exchanger comprises a coil and a metal corrugated pipe. The coil type heat exchanger is characterized in that the metal corrugated pipe with the large caliber is mounted in the coil, openings in the two ends of the metal corrugated pipe are exposed out of openings in the two ends of the coil, and the openings in the two ends of the coil and the outer wall of the metal corrugated pipe are sealed through injection molding, hot melting, welding or colloid; a first joint is mounted at one end of the coil, a second joint is mounted at the other end of the coil, a third joint is the opening in one end of the metal corrugated pipe, and a fourth joint is the opening in the other end of the metal corrugated pipe; the metal corrugated pipe is a copper corrugated pipe or a stainless steel corrugated pipe; and the coil is a rubber coil or a plastic coil. According to the coil type heat exchanger, the runner is long, the metal corrugated pipe with the large caliber is used for flowing of waste hot water, blocking is not likely to happen, the heat exchange efficiency is high, and the coil type heat exchanger can be widely applied to recovery of waste hot water and hot energy generated in household bathing, hairdressing and beauty, large bath centers and industrial production.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a coil heat exchanger. Background technique [0002] In daily life and industrial production, in order to improve the heat exchange efficiency of the heat exchanger, the diameter of the flow channel of the heat exchanger should be made as small as possible. The flow channel is easily blocked; at the same time, the flow channel of the heat exchanger is short, and the temperature difference at the hot end of the heat exchanger is large (the temperature difference at the hot end refers to the temperature difference between when the hot medium flows into the heat exchanger and when the cold medium flows out of the heat exchanger), and the heat recovery efficiency is low However, the economic benefits of heat recovery are not significant, and the problem of recovering waste hot water heat in household baths, beauty salons, large bath centers and industrial production has not been well res...
