Separated heat pipe system capable of adjusting flow resistance and using method

Abstract

The invention discloses a separated heat pipe system capable of adjusting flow resistance and a using method thereof, solves the problem of failure of the heat pipe system due to increase of closing on-way resistance caused by increase of fluid flow rate in the heat pipe system, and has the advantages that on-way resistance adjustment can be realized, and an ascending pipe or a descending pipe is convenient to replace. According to the specific scheme, the separated heat pipe system capable of adjusting the flow resistance comprises an evaporator, a condenser, an ascending pipe component and a descending pipe component, the condenser is higher than the evaporator, one side of the evaporator and one side of the condenser are connected through the ascending pipe component, and the other side of the evaporator and the other side of the condenser are connected through the descending pipe component. The ascending pipe component and the descending pipe component respectively comprise a plurality of pipelines which are arranged in parallel and can be communicated, the pipelines of the ascending pipe component and the descending pipe component are connected through valves, the flow resistances of the pipelines in the ascending pipe component are different, and the flow resistances of the pipelines in the descending pipe component are different.

Description

technical field [0001] The invention relates to the field of heat pipes, in particular to a separate heat pipe system with adjustable flow resistance and its use method. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Heat pipes are more and more widely used in electronic products and daily life. Due to the separability of the evaporator and condenser, the separated heat pipe has a wider range of applications than the traditional integral heat pipe. It can be applied to the situation where the heat source and the cold source are far apart, or the cold source and the heat source are located indoors and outdoors. At the same time, the hot and cold ends can exchange heat with different fluids, preventing the mutual leakage of the hot and cold ends. [0004] However, the separated heat pipe also has a certain heat transfer limit. The invento...

Problems solved by technology

[0004] However, the separated heat pipe also has a certain heat transfer limit. The inventor found that under the condition of high heat flux density, the steam flow rate and condensate flow rate in the heat pipe increase, and the flow rate of the fluid increases, resulting in an increase in the resistance along the tube wall. , the circulation of the working fluid is blocked, and the gravity of the working fluid in the heat pipe may not be enough to drive the flow of the working fluid, so that the entire heat pipe system fails; or the temperature of the tube wall at the heat pipe evaporator is too high for a long time or fluctuates for a long time, Fatigue or damage to the local pipe wall, resulting in failure of the heat pipe system
