New description: [New technical field] The present invention relates to a heat pipe, and in particular to a thin tube. ί,,, Ρ [Prior Art] Generally, electronic equipment generates heat during operation. If this heat is not effectively removed, electronic equipment is prone to crash conditions. In severe cases, it may burn. Destroy electronic components in electronic equipment, causing property damage or injury to users. Therefore, designers often set thermal modules in electronic devices. In recent years, due to the high performance of electronic wafers, a souther temperature* has also been generated, making the heat dissipation module corresponding to the electronic chip more and more important. The heat pipe is a commonly used heat sink. The inner wall of the heat pipe has a capillary structure with a working fluid therein. When one end of the heat pipe is placed at a higher temperature such as an electronic wafer and the other end is placed at a lower temperature, the working fluid adsorbed by the capillary structure at a high temperature starts to evaporate. The vaporized gas collects in the space inside the tube, and the gaseous fluid flows toward the low temperature of the heat pipe due to the pressure. When the gaseous fluid reaches a low temperature, it begins to condense into a liquid fluid, which is recycled by the capillary structure at a low temperature.

The cross-sectional shape thereof may be U-shaped. Another aspect of the present invention is an electronic device using a heat pipe, comprising a substrate, an electronic thinning and a heat pipe. The electronic component is disposed on the substrate, and the heat pipe is disposed on the electronic component.

The heat pipe may have an L-shaped cross section. In another embodiment, the heat pipe further includes a third portion located outside the electronic component, connected and electrically connected to the other end of the second portion, and the third portion extends along the short axis of the heat pipe toward the substrate. The height of the section is greater than the height of the section of the second part. The shape of the heat pipe can be U-shaped. Material == Yuan: The outer side is bent downwards, and the fam of the electronic component board can be effectively utilized, and the air flow path of the heat pipe can be increased without increasing the situation, and the degree of the heat pipe is increased.

Taking this embodiment as an example, the electronic device 1 can be a notebook computer, the electronic component 3 can be a central processing unit chip, and the substrate 500 is a central processing unit substrate. The electronic component 300 is disposed on the substrate 500, and generally the area of the substrate 500 is larger than the electronic component 300 such that a step is formed between the electronic component 300 and the substrate 5A. The heat pipe 400 uses the space between the electronic component 3 and the substrate 5 to increase the air flow path in the heat pipe 400. Specifically, the heat pipe 400 is substantially flat to match the dimension of the electronic device 100. The heat pipe 400 extends downward in the direction of the substrate 500 outside the electronic component 3A along one end of the short axis X to locally increase the thickness of the heat pipe 4''. This short axis X especially refers to the lateral short axis after the heat pipe 4qq is flattened. In other words, the heat pipe 400 includes a first portion 410 and a second portion 420 that extends in the direction of the substrate. In a specific embodiment, the first portion 410 and the second portion 42 are perpendicular to each other. The heat pipe 4A exceeds the cross-sectional height hi of the first portion 41 of the outer edge of the electronic component 300 to be greater than the cross-sectional height of the second portion 420 of the heat pipe 400 on the electronic component 300. The first portion 410 can be in contact with or not in contact with the electronic component 3, and the second portion 420 is in contact with the electronic component 300. The heat pipe 400 has a cross-sectional shape that approximates an L shape. Compared with the traditional inline design (only the first portion 410), the heat pipe 400 of the present invention effectively utilizes the space between the electronic component 300 and the substrate 500 to increase without increasing the overall height of the electronic device 1 The air flow path in the heat pipe 400 is used to increase the heat dissipation efficiency of the heat pipe 4〇〇.

The wearing height hi of the first portion 410 of the heat pipe 4 is greater than the sectional height h2 of the second portion 420. The heat pipe 400 adds a first portion 410' extending downward from the side to increase the space of the air flow passage 406 in the heat pipe 400, thereby improving the heat dissipation efficiency of the heat pipe 400. Referring to Fig. 3, there is shown a schematic view of an electronic device to which another embodiment of the heat pipe of the present invention is applied. The electronic device 1A includes a housing 200, an electronic component 300, a heat pipe 400, and a substrate 500.

In this embodiment, the heat pipe 400 includes a first portion 410' extending from the side of the electronic component 300 toward the substrate 500 and a second portion 420 located above the electronic component 300, and further includes the other side of the slave electronic component 300. A third portion 430 extending in the direction of the substrate 500. That is, the heat pipe 400 is bent downward along one end of the short axis X to form a first portion 410. The heat pipe 400 is bent downward along the other end of the short axis X to form a third portion 430. The first portion 410 and the third portion 430 are respectively located on opposite sides of the second portion 420, that is, the first portion 410 and the third portion 430 are located on both sides of the electronic component 300. The first portion 410 and the third portion 430 may or may not be in contact with the electronic component 300, and the second portion 420 may be in contact with the electronic component 300. The heat pipe 400 has a cross-sectional shape that approximates a dome shape. Compared with the conventional inline design, the heat pipe 400 of the present invention effectively utilizes the space between the electronic component 3 and the substrate 500 to increase the air flow path in the heat pipe 400 without increasing the overall height of the electronic device 100.
