Abstract

The invention discloses a line-up type full-contact heat exchange tube and relates to the technical field of liquid and gas heat exchange, in particular to heat energy exchange and recovery. The line-up type full-contact heat exchange tube comprises an internal tube, a spiral guiding extend-range ferrule and an external tube; both the internal tube and the spiral guiding extend-range ferrule are arranged inside the external tube and are coaxial to the same; the spiral guiding extend-range ferrule sleeves the internal tube from the outer wall and is arranged inside the external tube, and a spiral guiding channel is formed between the internal tube and the external tube. The spiral guiding extend-range channel is formed between the spiral guiding extend-range ferrule and the internal and external tubes, flow length of materials in the channel is effectively increased, contact area and contact time of refined materials and a heat exchange conductor are increased, and uniformity in heat exchange is improved; the internal tube is arranged inside the spiral guiding extend-range channel, the materials inside and outside the material channel are subjected to heat exchange simultaneously, and utilization upon generation is achieved; the line-up type full-contact heat exchange tube is more complete in heat exchange, high in heat exchange efficiency, more compact in structure, good in shaping, flexible to use, wide in applicability and especially suitable for energy-saving recovery of instant heat exchange.

Description

technical field [0001] The invention patent relates to the technical field of liquid and gas heat exchange, mainly involving heat energy exchange and recycling. Background technique [0002] Conventional heat exchangers include plate heat exchangers, shell and tube heat exchangers, etc. The plate heat exchanger has a short flow path and relies on fins for heat dissipation, which is not suitable for instant heat exchange with large temperature rise. The shell-and-tube heat exchanger has a water storage flow channel, and the heat exchange body participates in the heat exchange, and the mass of the heat exchange is large, and excess heat energy is wasted. Environmental protection and energy saving are the green life that human beings should advocate. Recycling and reuse of heat energy, especially recycling immediately after use, is an avant-garde energy-saving concept. There is no storage and no excess heat loss, and the waste heat generated immediately is fully recovered and ...
