Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a degassing mechanism for a heat pipe. Background Art

[0002] Heat pipe radiators are a common type of radiator. During use, the heat pipes need to be vacuumed and degassed. With the rapid development of the heat dissipation industry, the overall performance requirements for radiators are becoming increasingly higher, and product stability has become an important condition.

[0003] During the production process of radiator heat pipes, the heat pipes need to be evacuated (degassed). However, the existing heat pipe evacuation devices only use the same heat pipe degassing structure regardless of the heat pipe type being processed, which can easily lead to the following problems:

[0004] 1. Problems caused by an oversized degassing channel: As we all know, too much or too little working fluid in a product will inevitably prevent the radiator from entering its optimal working state, leading to an imbalance in the heat dissipation of the heat dissipation component. When the temperature is high, the heat cannot be removed, which will cause problems such as unstable radiator energy efficiency.

[0005] 2. The problem of unstable extraction (degassing) volume: Most heat pipe degassing channels are directly connected to the vacuum pump, which will result in the degassing channel being too large. Some heat pipes with poor capillary or heat pipes that exceed 100% of the water demand will have problems such as too small thermal resistance, insufficient efficiency, and burning out due to the large fluctuation in the amount of water taken away by degassing.
