The invention provides a hot pipe. The hot pipe comprises an evaporation collector, a condensation collector, a rising pipe and a return pipe; the rising pipe is communicated with the evaporation collector and the condensation collector, the evaporation collector is located at the lower portion, the condensation collector is located at the upper portion, and fluid absorbs heat and evaporates in the evaporation collector, enters the condensation collector through the rising pipe, and condensates after being subjected to heat transfer in the condensation collector; the condensed fluid returns tothe evaporation collector through the return pipe; flow stabilizing devices are arranged in the rising pipe, small holes are formed in adjacent through holes, and communication of the through holes is achieved through the small holes. Through the formation of the small holes, it can be guaranteed that the adjacent through holes are communicated with one another, pressure among the through holes can be made uniform, so that the fluid of a high-pressure flow channel flows to low pressure; meanwhile, a liquid phase and a gas phase can be further separated when the fluid flows, and stabilizationof two-phase flowing is further promoted.

The invention provides a shell-and-tube heat exchanger comprising a shell. Sealing heads are arranged at the two ends of the shell, pipe plates are arranged at the connection positions of the sealingheads and the shell, a heat exchange pipe is connected with the pipe plates at the two ends, a gas phase in gas-liquid two-phase flow is insoluble or poorly-soluble gas, in other words, the gas cannotbe dissolved in liquid in the heat exchange process, a separating device is arranged in the heat exchange pipe and is of a sheet-like structure, and the sheet-like structure is arranged on the crosssection of the heat exchange pipe; and the separating device is composed of square through holes and regular octagonal through holes, the side length of the square through holes is equal to the side length of the regular octagonal through holes, the four sides of each square through hole are the sides of four different regular octagonal through holes, and the four mutually-spaced sides of each regular octagonal through hole are the sides of four different square through holes. According to the heat exchanger with the separating device of the new structure, when the gas-liquid two-phase flow exists in the pipe, compared with the background art, heat transfer is further enhanced, vibration of the pipe is weakened, and the noise level is reduced.
