Description

technical field [0001] The invention belongs to the technical field of heat exchange devices, relates to a segmented spiral condensation heat exchange device, and also relates to a heat exchange method of the segmented spiral condensation heat exchange device. Background technique [0002] Condensing heat exchangers generally refer to heat exchangers that utilize the latent heat of vaporization. When the heat exchange temperature is lower than the saturation temperature of the gaseous thermal working medium, the working medium will condense into a liquid state to release the latent heat of vaporization. Condensation and heat release are used in many scenarios, such as: air conditioning systems, heat pump engineering systems, etc. [0003] Existing condensing heat exchangers mainly include shell-and-tube type and coil type. The structure of the coil type is basically the same as that of the general shell-and-tube heat exchanger. The high-temperature working fluid condenses ...
