AI Technical Summary
The existing heat pipes do not utilize the liquid power in the capillary structure, and the waterway is single, making it difficult to achieve better heat dissipation effect.
Water channels are set up on both sides of the capillary structure to form an inner and outer water channels structure, making full use of the driving force of the capillary structure.
By setting up internal and external waterway structures, the driving force of the capillary structure can be used more effectively to achieve better heat dissipation effect.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of heat pipes, in particular to a heat pipe. Background Art
[0002] The existing heat pipe is mainly formed by stretching a groove on the inner side of the heat pipe, and then using a core rod as an auxiliary inside the heat pipe. A capillary structure is formed by filling copper powder and sintering between the core rod and the heat pipe. The capillary structure provides a capillary force to drive the liquid to reflux, thereby achieving a good heat dissipation effect. The water channel in the heat pipe is arranged in the middle, the water channel is relatively simple, and the capillary structure does not make sufficient use of the driving force of the liquid in the water channel. If water channels are arranged on both sides of the capillary structure, the driving force of the capillary structure can be fully utilized to achieve a better heat dissipation effect. Utility Model Content
[0003] The main purpose of the utility model is to provide a heat pipe which can fully utilize the driving force of the capillary structure by arranging water channels on both sides of the capillary structure, thereby achieving a better heat dissipation effect.
[0004] The utility model provides a heat pipe, comprising a heat pipe body and a capillary structure formed by sintering copper powder and arranged in the heat pipe body;
[0005] A plurality of uniformly arranged strip-shaped protrusions are arranged on the inner side of the heat pipe body, the cross section of the protrusions is a convex shape, a first groove on the lower side and a second groove on the upper side are formed between the protrusions, and the width of the first groove is smaller than that of the second groove;
[0006] The diameter of the copper powder is smaller than the second groove and larger than the first groove. The sintered capillary structure is arranged between the second grooves and on the outside of the second groove, so as to form an inner water channel on the inner side of the capillary structure and an outer water channel on the outside of the capillary structure.
[0007] Preferably, the width of the first groove is much smaller than that of the second groove.
[0008] Preferably, the protrusion and the heat pipe body are integrally formed.
[0009] The beneficial effects of the heat pipe of the utility model are:
[0010] 1. By setting convex-shaped bumps, first grooves on the upper and lower sides and a second groove on the upper side can be formed between the bumps, and the diameter of the copper powder is smaller than the second groove and larger than the first groove, so that an inner water channel can be formed on the inner side of the capillary structure and an outer water channel can be formed on the outer side of the capillary structure, so that the driving force of the capillary structure can be fully utilized to achieve better heat dissipation effect.

[0014] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0015] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0016] Reference Figure 1 and Figure 2 , an embodiment of the heat pipe of the utility model is proposed:
[0017] A heat pipe comprises a heat pipe body 1 and a capillary structure 2 formed by sintering copper powder and arranged in the heat pipe body 1;
[0018] A plurality of uniformly arranged strip-shaped protrusions 11 are arranged on the inner side of the heat pipe body 1. The cross section of the protrusion 11 is a convex shape. The protrusion 11 includes a first protrusion 111 at the bottom and a second protrusion 112 at the top. The width of the first protrusion 111 is much larger than that of the second protrusion 112. Between adjacent protrusions 11, a first groove 113 on the lower side is formed between the first protrusions 111, and a second groove 114 on the upper side is formed between the second protrusions 112. The width of the first groove 113 is much smaller than that of the second groove 114.
[0019] The diameter of the copper powder is smaller than the second groove 114 and larger than the first groove 113. The sintered capillary structure 2 is arranged between the second grooves 114 and on the outer side of the second groove 114, so that an inner water channel 4 is formed on each first groove 113 on the inner side of the capillary structure 2, and an outer water channel 4 is formed on the outer side of the capillary structure 2. Since the heat pipe will be flattened when it is finally used, the thickness of the outer water channel 3 will not be much different from that of the inner water channel 4 when used.
[0020] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
