Embodiment 1

[0043] A cleaning method for complex channel heat pipes, comprising the following steps:

[0044] (1) Oil washing: immerse the complex channel heat pipe in a cleaning tank filled with gasoline, and clean for 20 minutes.

[0045] (2) High-pressure water washing: Take out the oil-washed complex channel heat pipe from the cleaning tank, and then clean the inner and outer walls of the heat pipe with 60L / min high-pressure water in a high-pressure cleaner for 5 minutes.

[0046] (3) Ultrasonic alkaline cleaning: Immerse the complex channel heat pipe after high-pressure water washing in an ultrasonic cleaning machine filled with a 5% NaOH solution for 5 minutes.

[0047] (4) Ultrasonic water washing: immerse the complex channel heat pipe after ultrasonic alkali washing in an ultrasonic cleaning machine filled with pure water, and clean for 10 minutes.

[0048] (5) Deionized water washing: Take out the complex channel heat pipe after ultrasonic washing and fix it on the tooling of th...

Embodiment 2

[0052] (1) Oil washing: immerse the complex channel heat pipe in a cleaning tank filled with gasoline, and clean for 40 minutes.

[0053] (2) Drying with nitrogen: Take out the oil-washed complex channel heat pipe from the cleaning tank, and then blow dry the inner cavity of the complex channel heat pipe with nitrogen for 30-60 seconds.

[0054] (3) Ultrasonic alkaline cleaning: Immerse the complex channel heat pipe after high-pressure water washing in an ultrasonic cleaning machine filled with a KOH solution with a mass concentration of 5%, and clean it for 10 minutes.

[0055] (4) Ultrasonic water washing: immerse the complex channel heat pipe after ultrasonic alkali washing in an ultrasonic cleaning machine filled with pure water, and clean for 20 minutes.

[0056] (5) Deionized water washing: Take out the complex channel heat pipe after ultrasonic washing and fix it on the tooling of the high-pressure cleaner, and use 10L / min flow rate of deionized water to rinse the inner...

Abstract

The invention relates to a cleaning method of a complex grooved heat pipe. The cleaning method of the complex grooved heat pipe comprises the following steps of: (1) removing oil by using gasoline; (2) drying residual oil drops by using nitrogen; (3) carrying out ultrasonic alkali cleaning; (4) carrying out ultrasonic water cleaning; (5) washing by using a high-pressure washer; (6) drying by using the nitrogen; and (7) drying by using a baking oven. In the invention, oil dirt, oxide layers and other impurities which are positioned on the surface and in an inner cavity of the complex grooved heat pipe are cleaned by adopting the cleaning methods, such as oil removal, alkali cleaning, water cleaning, and the like, and accessorily adopting tools and means, such as ultrasonic, a high-pressure pump, gas protection, and the like, the complex grooved heat pipe shows a natural metal color after cleaned, and therefore, the production efficiency of the complex grooved heat pipe is ensured and the quality of the complex grooved heat pipe is enhanced.

Description

technical field [0001] The invention relates to a heat pipe cleaning method, in particular to a cleaning method for complex channel heat pipes. Background technique [0002] Heat pipe is an efficient heat transfer element, which has advantages that traditional heat transfer devices cannot match, such as uniform temperature distribution, small thermal resistance, large heat transfer, and simple structure. Therefore, it is widely used in various fields of industrial production. However, heat pipes must be cleaned before processing and use. Cleaning is a key link in the production of heat pipes, and the quality of cleaning directly affects the quality of heat pipe products. [0003] At present, the heat pipe cleaning methods mainly include manual cleaning and ultrasonic cleaning. However, neither of these two methods can completely remove the tiny oil and oxide layer remaining on the inner wall of the heat pipe, especially for heat pipes with complex channel structures (such ...
