The invention provides a rod-fin type loop heat pipe with varying sizes. The rod-fin type loop heat pipe includes an evaporation header, a condensation header, rising pipes and return pipes, flow stabilizing devices are arranged in the rising pipes, the flow stabilizing devices each include a core body and an outer shell, the core bodies are arranged in the outer shells, the outer shells are connected and fixed to the inner walls of the rising pipes, the core bodies each include a plurality of radial rods extending from the centers of the core bodies to the radial direction, and a plurality offins extending downwards from the radial rods are arranged on each radial rod; and the core bodies each include a core column arranged at the center of each core body, one ends of the radial rods arefixed into the core columns, and from the core columns of the rising pipes to the radial extension direction, the size of the fins on the same radial rods is getting larger and larger. According to the rod-fin type loop heat pipe with the varying sizes, the size of the fins on the rising pipe walls is increased, so that the ability to cut vapor phases and liquid phases near the pipe walls is enhanced. The ability to cut near the pipe walls is focused to be strengthened, and noise reduction and vibration damping can be targeted for specific situations, so that the effects of noise reduction and vibration damping are further achieved, and meanwhile, heat transfer can be further enhanced.

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.
