TL;DR: In this paper, a micro array heat pipe gas-liquid countercurrent flow heat exchange device is described, which is suitable for the fields of natural machine room cooling, waste heat recovery and the like.
Abstract: The invention discloses a micro array heat pipe gas-liquid countercurrent flow heat exchange device and belongs to the field of heating, ventilating and air conditioning equipment. The device comprises a fan, a shell, a plurality of micro array heat pipe plates and a liquid side heat exchange box. The micro array heat pipe plates are fixed in the shell in parallel. The two gas-liquid sides are separated by a gas-liquid partition plate. The micro array heat pipe liquid side part stretches into the liquid side heat exchange box, and the micro array heat pipe gas side part is externally connected with the fan. The liquid side heat exchange box comprises a liquid separation main channel, a liquid collection main channel and branch heat exchange channels arranged in parallel. Baffling plates are arranged in the branch heat exchange channels in a staggered mode, the heat exchange area is increased, the resistance is increased properly, and hydraulic equilibrium between branches is facilitated; meanwhile, the overflowing area is reduced, heat exchange can be strengthened and pump consumption is reduced. The micro array heat pipe gas-liquid countercurrent flow heat exchange device is light and ingenious in structure and high in safety, achieves gas and liquid countercurrent flow heat exchange, greatly improves the heat exchange ability, reduces pump consumption, and is particularly suitable for the fields of natural machine room cooling, waste heat recovery and the like.

TL;DR: In this paper, a pressure swing distillation with countercurrent heat integration process was adopted to substitute normal distillation process to save energy, which can save 255 percent of steam and 316 percent of cooling water.
Abstract: Different distillation processes of methanol-water mixture solution were evaluated and comparedA pressure swing distillation with countercurrent heat integration process was adopted to substitute normal distillation process to save energyThe pressure swing distillation process model was established,simulation calculation was done by steady state methodThe operation parameters of distillation separation system were discussed and optimized to minimize the energy consumptionThe results show that the pressure swing distillation with countercurrent process requires smaller pressure difference and can save 255 percent of steam and 316 percent of cooling water

TL;DR: In this paper, the frequency and amplitude of the vibrations are controlled in relation to the throughput to maintain uniform injection of droplets of one of the immiscible or partially miscible liquids into the other.
Abstract: 1,035,613. Contact heat exchangers. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 29, 1963 [May 9, 1962], No. 16757/63. Heading F4K. [Also in Division B1] Heat is exchanged between two liquids which are immiscible or partially miscible, by feeding said liquids in countercurrent flow through a column 1. The column includes a vibrator 7 for the liquid therein and is closed at its ends by bellows 8, 9. The frequency and amplitude of the vibrations are controlled in relation to the throughput to maintain uniform injection of droplets of one of the liquids into the other. As shown water flows through the column 1 from an inlet 2 to an outlet 3. Droplets of isobutyl alcohol are introduced into the water through an injector 5 from a pressurized feed tank 10 by a vibratory device 16 operating at a higher frequency than the vibrator 7, and are withdrawn from the upper end of the column at 6. The injector 5 may alternatively be at the top of the column, the droplets then flowing downwardly.
