Abstract

The invention discloses an inner structure of a Taichi type volute inner container heat exchanger. The inner structure is formed by continuously connecting a plurality of sections of tubular heat exchanger main pipes end to end. The main pipes are arranged in parallel vertically. A volute inner container with a Taichi figure type radial section is arranged in the main pipe so that the space in the pipe is separated into two mutual intersection parts. A fluid with heat is usually introduced in the volute inner container. A cold fluid with lower temperature flows in the space between the outer wall of the volute inner container and the pipe wall of the main pipe. Plane sealing heads matched with the Taichi figure type volute inner container are arranged at the two ends of the main pipe. A closed U-shaped bend communicated with the head end of the next section of main pipe is arranged at the tail end of the main pipe. A cold fluid inlet is arranged at the head part of the outer wall of the main pipe. A heated cold fluid outlet is arranged at the tail part of the outer wall of the main pipe. The outlet is also in connected communication with the inlet of the head part of the next section of main pipe. The two fluids are in a converse flowing manner. The Taichi type volute inner container heat exchanger is relatively easy to manufacture, higher in exchange contact area and higher in heat exchange efficiency. The Taichi type volute inner container heat exchanger is applied to exchanging heat between two kinds of liquid and can also be used as a condenser.
