Heat exchanger capable of automatically adjusting heat exchange area

Abstract

The present invention discloses a heat exchanger capable of automatically adjusting heat exchange area, which relates to the field of heat exchangers. The key points of the technical solution of the present invention include a heat exchange wall, which includes a fixed heat exchange wall, and a self-adjusting heat exchange wall that can automatically expand and contract according to the flow or temperature of the fluid to change the heat exchange area. The present invention can automatically change the heat exchange area, and timely respond and adapt to different working conditions, having simple structure, low production cost and good stability.
