Liquid-cooled heat exchanger based on spiral structure

Abstract

The invention relates to a liquid-cooled heat exchanger based on a spiral structure, solving the problems of effectively reducing the temperature of an electrolyzed gas-liquid mixture and preventing device corrosion when hydrogen and oxygen are prepared by electrolytic water. The heat exchanger comprises a cooling chamber, a radiating pipe, an inner pipe and a bracket, wherein the cooling chamber is a sealed container, and both ends of the cooling chamber are provided with an inlet and an outlet; the radiating pipe is positioned in the cooling chamber, both ends of the radiating pipe are respectively used as an inlet and an outlet, and both the inlet and the outlet extend out of the cooling chamber by through holes of the cooling chamber; a body of the radiating pipe is in a ripple structure, and both the inner surface and the outer surface of the pipe are provided with ripples; the part of the radiating pipe, which is positioned in the cooling chamber, is in a spiral structure and is positioned between the inlet and the outlet of the cooling chamber; and the radiating pipe as well as the inlet and the outlet of the radiating pipe are made of steel or stainless steel. The liquid-cooled heat exchanger has favorable radiating effect and is difficult to interfere by the external environment.

Description

technical field [0001] The invention relates to a liquid-cooled heat exchanger, which is used for effectively reducing the electrolyzed gas-liquid mixture when electrolyzing water to prepare hydrogen and oxygen, and preventing the cooling device from being corroded. Background technique [0002] In industrial production, when electrolysis of water is used to prepare high-purity hydrogen and oxygen, the temperature of the gas generated after electrolysis and the solution that has not been electrolyzed is very high, and it cannot be separated from gas and liquid immediately, so heat exchange must be used first The device cools it down. [0003] Existing exchangers for cooling the electrolyte heat are generally classified into air-cooled and liquid-cooled (also called water-cooled). The cooling effect of the air-cooled heat exchanger is low, and is often affected by the actual air temperature, so that the cooling effect cannot meet the cooling requirements of the electrolyte. ...
