Title
(EN) HEAT PIPE FOR SMART TERMINAL, AND MANUFACTURING METHOD FOR SAME
(FR) CALODUC POUR BORNE INTELLIGENTE ET SON PROCÉDÉ DE FABRICATION
(ZH) 智能终端热管及其制作方法
Abstract
(EN)
A heat pipe for a smart terminal comprises an upper copper plate (10) and a lower copper plate (20) stacked and welded together. A top surface of the lower copper plate (20) is provided with a groove (21) in a lengthwise direction thereof. A liquid channel (22) formed by means of copper powder sintering is provided within the groove (21). A gas channel (23) is provided between edges of the liquid channel (22) and the groove (21). A liquid is provided within the liquid channel (22), and the groove (21) is in a negative vacuum pressure state. The heat pipe for a smart terminal is formed by stacking and welding the upper copper plate (10) and the lower copper plate (20), such that the upper copper plate (10) and the lower copper plate (20) can be directly configured as a required shape, and configuring a specific shape does not require additional bending after formation. Thus, the manufacturing process is not restricted by shape or size, creates no creases, and is highly applicable. An internal liquid channel (23) is also formed by means of copper powder sintering to provide superior heat dissipation.

L'invention concerne un caloduc pour borne intelligente, qui comprend une plaque de cuivre supérieure (10) et une plaque de cuivre inférieure (20) empilées et soudées ensemble. Une surface supérieure de la plaque de cuivre inférieure (20) est munie d'une rainure (21) dans son sens longitudinal. Un canal de liquide (22) formé par frittage de poudre de cuivre est ménagé à l'intérieur de la rainure (21). Un canal de gaz (23) est disposé entre les bords du canal de liquide (22) et la rainure (21). Un liquide est disposé à l'intérieur du canal de liquide (22), et la rainure (21) est dans un état de pression sous vide négative. Le caloduc pour borne intelligente est formé par empilement et soudage de la plaque de cuivre supérieure (10) et de la plaque de cuivre inférieure (20), de sorte que la plaque de cuivre supérieure (10) et la plaque de cuivre inférieure (20) puissent être réalisées directement dans la forme requise, et la réalisation dans une forme spécifique ne nécessite pas de courbure supplémentaire après formation. Ainsi, le procédé de fabrication n'est pas limité en ce qui concerne la forme ou la taille, ne crée pas de plis, et présente une grande applicabilité. Un canal de liquide interne (23) est également formé par frittage de poudre de cuivre et produit une dissipation thermique supérieure.
