Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to a mobile phone heat pipe and a production method of an oxygen-free copper pipe for the mobile phone heat pipe. The mobile phone heat pipe comprises a transmission section, and a heat absorption section and a heat dissipation section which are formed at two opposite ends of the transmission section. The transmission section is in an arc bent pipe shape and comprises a first extension part and a second extension part which are perpendicular to each other. The joint of the first extension part and the second extension part is arc-shaped. The heat absorption section is arranged on the first extension part in a protruding mode, the heat dissipation section is arranged on the second extension part in a protruding mode, the inner diameter and the outer diameter of the heat dissipation section are gradually increased in the direction away from the second extension part, and the outer diameter of the oxygen-free copper pipe for the mobile phone heat pipe is 8-10 mm and the thickness of the wall is 0.075-0.12 mm. The roundness of the oxygen-free copper pipe for the mobile phone heat pipe is smaller than or equal to 0.5%, and the diameter-thickness ratio of the oxygen-free copper pipe for the mobile phone heat pipe is 80: 1 or above. The mobile phone heat pipe is high in heat dissipation efficiency.

Description

technical field [0001] The invention relates to a production method of an oxygen-free copper tube for a mobile phone heat pipe and the mobile phone heat pipe. Background technique [0002] Mobile phones have gradually become popular, and the main board in the mobile phone will emit more heat, and in order to facilitate heat dissipation, there will be different designs. For example, for a computer, a small exhaust fan is installed, the main purpose of which is to cool the case. But for a mobile phone that is only the size of a palm, it is impractical to install a fan. In order to achieve the purpose of heat dissipation, various mobile phone manufacturers also use their own tricks. With the rise of game phones, this cooling method has gradually entered our field of vision. At present, the most famous one is copper tube cooling, which is commonly known as mobile phone heat pipe. The mobile phone heat pipe uses the principle of evaporation and condensation to transfer the he...
