Description

Technical Field

[0001] The present invention relates to the field of heat pipes, and particularly to a support column for a VC heat pipe. Background Art

[0002] In general, in order to enable the working fluid to flow back, a capillary structure is provided on the inner wall of the housing of a heat pipe. In order to prevent the heat pipe from collapsing, a large number of support columns must be added between the upper and lower plates. Usually, the support columns are solid, and a large number of support columns occupy the space between the two plates, which has a negative impact on heat transfer. In the existing designs, in order to improve the heat dissipation effect of the heat pipe, hollow support columns are often provided, and support column side through holes are provided at the top and bottom of the side of the support column to improve the heat dissipation effect of the heat pipe by setting the support column side through holes. However, the heat dissipation effect of the support columns in the existing designs is relatively poor. Therefore, a support column for a VC heat pipe with a simple structure, a capillary structure inside and a good heat dissipation effect is needed. Summary of the Invention

[0003] The main object of the present invention is to provide a support column for a VC heat pipe with a simple structure, a capillary structure inside and a good heat dissipation effect.

[0004] The present invention provides a support column for a VC heat pipe, including a support column body, an upper connector provided at the top of the support column body, and a lower connector provided at the bottom of the support column body;

[0005] A body through hole is provided in the middle of the support column body, a body capillary groove is provided on the inner side surface of the body through hole, at least two flaring grooves are provided between the body capillary grooves, and connector capillary grooves are provided on the upper connector and the lower connector;

[0006] The upper connector and the lower connector are respectively composed of at least two upper connector bodies and lower connector bodies, and the upper connector bodies and the lower connector bodies are formed by cracking from the flaring grooves when the upper and lower ends of the support column body are flared;

[0007] The body capillary grooves in the support column body and the connector capillary grooves in the upper connector and the lower connector can endow the support column for a VC heat pipe with better heat transfer efficiency.

[0008] Preferably, the bottoms of the body capillary grooves and the connector capillary grooves are arc-shaped.

[0009] Preferably, the depth of the flaring groove is greater than that of the body capillary groove.

[0010] Preferably, the bottom of the flaring groove is triangular.

[0011] Preferably, the body capillary grooves and the connector capillary grooves correspond to each other and are connected.

[0012] The beneficial effects of the VC vapor chamber support column of the present invention are as follows:

[0013] 1. The capillary channels in the support column body, the upper connecting member, and the lower connecting member can connect the capillary pipelines of the upper connecting plate and the lower connecting plate of the vapor chamber, enabling rapid reflux of condensation and improving the heat transfer efficiency.

[0014] 2. The hollow support column body does not occupy space and does not affect the evaporation of the gas.

[0015] 3. The cracks formed after the flared grooves split can also allow more water to enter the through holes of the support column body more quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The realization, functional features, and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] 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.

[0022] Referring to Figures 1 to 3 , an embodiment of the VC vapor chamber support column of the present invention is proposed:

[0023] A VC vapor chamber support column 1 includes a support column body 11, an upper connecting member 12 provided at the top of the support column body 11, and a lower connecting member 13 provided at the bottom of the support column body 11.

[0024] A body through hole is provided in the middle of the support column body 11, a body capillary groove 111 is provided on the inner side of the body through hole, four flaring grooves 112 are provided between the body capillary grooves 111, and the four flaring grooves 112 are provided at equal angles. The bottom of the body capillary groove 111 is arc-shaped, and the bottom of the flaring groove 112 is triangular. The depth of the flaring groove 112 is greater than that of the body capillary groove 111. When flaring, the stress is more concentrated because the bottom of the flaring groove 112 is triangular, and it is thinner than the body capillary groove 111, so it is easier to crack when flaring.

[0025] The upper connector 12 and the lower connector 13 are respectively composed of at least four upper connector bodies and four lower connector bodies. The upper connector bodies and the lower connector bodies are formed by cracking from the expansion grooves 112 when the upper and lower ends of the support column body 11 are expanded. When expanding, the teeth will become shorter by 0.01mm. The capillary grooves 111 of the support column body 11 are expanded to form the connector capillary grooves 121. The capillary grooves 111 of the body and the capillary grooves 121 of the connector correspond to and are connected.

[0026] Through the body capillary groove 111 in the support column body 11 and the connection capillary groove 121 in the upper connection piece 12 and the lower connection piece 13, the capillary pipelines of the upper connection plate 2 and the lower connection plate 3 of the heat spreader can be opened, and the condensation can flow back quickly, improving the heat transfer efficiency. At the same time, the hollow support column body 11 does not take up space and does not affect the evaporation of the gas. In addition, the crack formed by the cracking of the expanded groove 112 can also allow more water to enter the body through hole of the support column body 11 more quickly.

[0027] 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 by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
