M252901 IV. Creative Instructions (l) [Technical Field to which the New Type belongs] This creative department provides a strong μ ^ ^ ^ ^ variety of flat and non-tapered heat pipe broadcasts, ε & The structure is especially capable of being heated at the end face of the heat pipe. ..., the area and at the same time [previous technology] Because the heat pipe has high heat transfer capacity, fast heat transfer, high heat transfer light, no moving components, simple structure and multi-purpose features: ', to transfer a large amount of heat without consuming electricity Therefore, it is very important to be able to dissipate heat. ι. For electronic products, please refer to the first figure. The heat pipe junction of Xi # 1 has an end surface that is tapered and has a sealing port 20a formed on the tapered end surface of its barrel 10a. The support body 40a is placed on the inner wall of the cylinder body 10a of the heat pipe, but the inner wall of the tapered end surface of the heat official is not provided with a capillary weave 30a and a support body 40a. However, the above-mentioned conventional heat pipe structure still has the following disadvantages: 1. The conventional heat pipe has a complex tapered end face with irregular tapered surfaces and welding points, so the inner wall generally does not have capillary structure. The setting of the setting is incomplete. Therefore, this irregular end face has no effect of rapid heat transfer and high thermal conductivity. Therefore, the end face of the heat pipe is usually not connected to a heat dissipation fin (not shown), and therefore space is wasted. 2 · The end face of the conventional heat pipe is tapered, which is difficult to join with the heat dissipation structure due to its complex shape, and the capillary structure inside the end face is incomplete, which makes it easy to contact the bottom surface of the heat source (not shown), which makes the use of the heat pipe inconvenient. , And therefore increase its volume.
