Abstract

The invention provides a heat exchange tube, a heat exchanger and a manufacturing method of the heat exchange tube. The heat exchange tube comprises a first panel and a second panel which are oppositely arranged. The outer side baffle and the inner side baffle are arranged between the first panel and the second panel. The outer side baffle is arranged on the outer side of the inner side baffle, the side, opposite to the outer side baffle, of the inner side baffle, the first panel and the second panel are enclosed to form a heat exchange flow channel, and the heat exchange tube further comprises a sealing piece arranged between the outer side baffle and the inner side baffle and used for blocking medium transfer between the outer side baffle and the inner side baffle. According to the heat exchange tube, the heat exchanger and the manufacturing method of the heat exchange tube, the sealing piece is arranged between the outer side baffle and the inner side baffle to block medium transfer between the outer side baffle and the inner side baffle, the leakage resistance when a heat exchange medium leaks is increased, the leakage amount is reduced, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to a heat exchange device in the field of heat transfer technology, in particular to a heat exchange tube with improved leakage prevention capability, a heat exchanger including the heat exchange tube and a manufacturing method of the heat exchange tube. Background technique [0002] Glass tubes have excellent corrosion resistance, especially circular glass tubes are used as heat exchange tubes for heat exchange devices due to their mature manufacturing process and low cost. However, circular glass tubes have the disadvantages of low heat transfer efficiency and insufficient structural compactness. Flat glass tubes can overcome the disadvantages of round glass tubes, but due to the limitations of the drawing process, the pass rate is extremely low when the cross-sectional aspect ratio is large, and based on the characteristics of the glass, the larger the aspect ratio, the flatter the drawn shape. The more severe the stress conce...
