Heat pipe

Abstract

The invention discloses a heat pipe which is characterized in that the heat pipe comprises an inner pipe (1) and an outer pipe (2), wherein one head of the inner pipe is closed, the other head of the inner pipe is opened, one head of the outer pipe (2) is closed, and the other head of the outer pipe (2) is opened; the opened head of the inner pipe (1) is inserted into the opened head of the outer pipe (2) along an axis and extends near the closed head of the outer pipe (2); a sealing ring (2-2) is arranged at the opened port of the outer pipe (2) and seals an annular opening between the outer pipe (2) and the inner pipe (1); a plurality of return pipes (3) made of a heat-insulating material uniformly pass through the sealing ring (2-2), respectively extend near the closed head of the inner pipe (1) and are respectively communicated with the inner pipe (1); and the outer pipe (2) is a condensing segment of the heat pipe, and a part of the inner pipe (1) arranged at the outside of the outer pipe (2) is an evaporation segment of the heat pipe. A vapor stream and a liquid stream in the heat pipe described by the invention are not mutually influenced, and the heat transfer efficiency is high.

Description

technical field [0001] The invention relates to a heat exchange device with an intermediate heat transfer medium in a closed pipe leading into or passing through the channel wall, in particular to a heat pipe. Background technique [0002] The heat pipe is a heat transfer element with extremely high thermal conductivity, which quickly transfers the heat of the heating object to the outside of the heat source through the evaporation and condensation of the liquid in the fully enclosed vacuum tube. Due to the advantages of high heat transfer efficiency and compact structure, heat pipes have been widely used in various heat dissipation occasions, solved the noise problem of traditional air-cooled heat dissipation, and opened up a new direction in the field of heat dissipation. [0003] A common heat pipe is a closed pipe body, one end of the pipe body is the evaporation end connected to the heat source, the other end is the cooling end, and a working medium is arranged in the p...

Problems solved by technology

However, since the steam channel and the return channel are respectively communicated with the evaporating part and the condensing part, part of the liquid must be vaporized in the return channel and flow back to the condensing part along the return channel, and there must be some liquid in the steam channel. After the gas is condensed, it flows reversely along the steam channel to the evaporation part, which obviously affects the heat exchange efficiency
