Description

Technical Field

[0001] The present invention belongs to the technical field of connectors, and in particular relates to an air-cooling heat dissipation structure and a connector having the same. Background Art

[0002] As the power of RF signals increases, the connector may be subjected to 4-5 times the power when using high-power transmission. As the power increases, the connector also generates heat, and may even reach an extreme high temperature of 125°C. When the connector is working continuously at high power, if the heat cannot be discharged in time, it will cause direct damage to the RF interface and the supporting coaxial cable, and even cause the entire connector to be scrapped. Summary of the invention

[0004] In order to achieve the above purpose and the above technical effect, the technical solution adopted by the present invention is:

[0005] A wind-cooled heat dissipation structure comprises a wind-cooled sleeve and a wind-cooled core tube, wherein the wind-cooled sleeve is hollow inside, the wind-cooled core tube comprises a main body core tube and a flow guide duct which are connected, the main body core tube is hollow inside, the main body core tube is inserted into the wind-cooled sleeve, and the flow guide duct is located outside the wind-cooled sleeve.

[0006] Furthermore, the air-cooling sleeve is a cylindrical structure with a hollow interior, one end of the air-cooling sleeve is closed, and the other end opposite to the air-cooling sleeve is open.

[0007] Furthermore, a plurality of small holes are provided on the side wall of the air-cooling sleeve, and the main body core tube and the air-cooling sleeve are welded together through the small holes, so that an air duct can be formed between the outer wall of the main body core tube and the inner wall of the air-cooling sleeve.

[0008] Furthermore, a plurality of small holes are symmetrically provided on the upper and lower surfaces of the side wall of the air-cooling sleeve, and the size of the small holes is Φ1 mm.

[0009] Furthermore, the main body core tube is an elliptical internal hollow tube, which is supported by the long axis of the ellipse and the inner wall of the air-cooling sleeve, and forms an air duct between the short axis of the ellipse and the inner wall of the air-cooling sleeve.

[0010] Furthermore, conical horn holes are symmetrically arranged on two opposite sides of the guide air duct to guide the wind direction.

[0012] Furthermore, the connector is provided with a plurality of air-cooling and heat-dissipating structures and a plurality of coaxial cables, and the heat generated by the connector is conducted away through the air-cooling and heat-dissipating structures.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The invention discloses an air-cooling heat dissipation structure and a connector having the same. When the connector is working, the heat generated is conducted to the air-cooling sleeve through the connection part. When the high-altitude airflow passes through the guide air duct and flows to the small-sized air duct through the conical horn hole, the flow rate of the wind increases, and a negative airflow pressure is formed here, which will suck out the airflow inside the main core tube. The airflow in the core tube drives the flow of hot air in the air-cooling sleeve, thereby discharging the internal hot air, and then sucking in cold air from the open end of the air-cooling sleeve to form a cycle, bringing out the heat inside the connector, achieving the effect of lowering the product temperature. The overall structure is simple, and air cooling can be achieved in different wind directions, avoiding damage to the radio frequency interface and the matching coaxial cable and the scrapping of the entire connector, and is suitable for industrial promotion and use.

[0021] The present invention is described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] A brief summary of one or more aspects is given below to provide a basic understanding of these aspects. This summary is not an exhaustive overview of all conceived aspects, and is neither intended to identify the key or critical elements of all aspects nor to define the scope of any or all aspects. Its only purpose is to give some concepts of one or more aspects in a simplified form as a prelude to a more detailed description that will be given later.

[0023] like Figure 1-7 As shown, the present invention discloses an air-cooled heat dissipation structure, comprising an air-cooling sleeve 1 and an air-cooling core tube 2, wherein the air-cooling sleeve 1 is hollow inside, one end of the air-cooling sleeve 1 is closed, and the other end is open, a plurality of small holes 3 are provided on the side wall of the air-cooling sleeve 1, the air-cooling core tube 2 comprises a main body core tube 4 and a guide air duct 5 which are connected, the main body core tube 4 is hollow inside, the main body core tube 4 is inserted into the air-cooling sleeve 1 and the two are welded together through the small holes 3, an air duct 6 can be formed between the outer wall of the main body core tube 4 and the inner wall of the air-cooling sleeve 1, the guide air duct 5 is located outside the air-cooling sleeve 1, and conical horn holes 7 are provided on opposite sides of the guide air duct 5 for guiding the wind direction.

[0024] In some embodiments, the air-cooling sleeve 1 is an internally hollow cylindrical tube, and the main core tube 4 is an internally hollow elliptical tube, which is supported by the long axis of the ellipse and the inner wall of the air-cooling sleeve 1, and an air duct 6 is formed between the short axis of the ellipse and the inner wall of the air-cooling sleeve 1.

[0025] The present invention also discloses a connector, including an air-cooling heat dissipation structure as described above. The connector 8 is provided with a plurality of air-cooling heat dissipation structures and a plurality of coaxial cables 9. The air-cooling heat dissipation structures are used to remove the heat inside the connector 8 through the circulation of air, thereby achieving the effect of lowering the product temperature and preventing heat accumulation from affecting the normal use of the connector 8.

[0026] When the connector 8 is working, the generated heat is conducted to the air cooling sleeve 1 through the connection part. When the high-altitude airflow passes through the guide air duct 5 and flows to the small-sized air duct through the conical horn hole 7, the air velocity increases, and a negative air pressure is formed here, which will suck out the airflow inside the main core tube 4. The core tube airflow drives the flow of hot air in the air cooling sleeve 1, thereby discharging the internal hot air, and sucking in cold air from the open end of the air cooling sleeve 1, forming a cycle, and realizing the air cooling cycle inside the air cooling sleeve 1.

[0027] Example 1

[0028] like Figure 1-7 As shown, an air-cooled heat dissipation structure includes an air-cooling sleeve 1 and an air-cooling core tube 2, wherein the air-cooling sleeve 1 is an internally hollow cylindrical copper tube, one end of the air-cooling sleeve 1 is closed, and the other end is open, 6 small holes 3 are opened on the upper and lower sides of the side wall of the air-cooling sleeve 1, and the size of the small holes 3 is Φ1mm, the air-cooling core tube 2 includes a main body core tube 4 and a guide air duct 5 that are connected, the main body core tube 4 is an elliptical internal hollow copper tube, the main body core tube 4 is inserted into the air-cooling sleeve 1 and the two are welded together through the small holes 3, the main body core tube 4 is supported by the long axis of the ellipse and the inner wall of the air-cooling sleeve 1, and an air duct 6 is formed between the short axis of the ellipse and the inner wall of the air-cooling sleeve 1, the guide air duct 5 is located outside the air-cooling sleeve 1, and conical horn holes 7 are set on opposite sides of the guide air duct 5 for guiding the wind direction.

[0029] A connector includes an air-cooling heat dissipation structure as described above. Four air-cooling heat dissipation structures and four coaxial cables 9 are evenly arranged on the connector 8, and the opening wind directions of the four conical horn holes 7 are different. By designing the air-cooling heat dissipation structure, the heat inside the connector 8 is taken out through the circulation of air, thereby achieving the effect of lowering the product temperature. At the same time, the air cooling effect under different wind directions can be achieved, thereby avoiding damage to the radio frequency interface and the matching coaxial cable 9 and the scrapping of the entire connector structure.

[0030] When the connector 8 is working, the generated heat is conducted to the air cooling sleeve 1 through the connection part. When the high-altitude airflow passes through the guide air duct 5 and flows to the small-sized air duct through the conical horn hole 7, the air velocity increases, and a negative air pressure is formed here, which will suck out the airflow inside the main core tube 4. The core tube airflow drives the flow of hot air in the air cooling sleeve 1, thereby discharging the internal hot air, and sucking in cold air from the open end of the air cooling sleeve 1, forming a cycle, and realizing the air cooling cycle inside the air cooling sleeve 1.
