As shown in fig. 1, the problem to be solved by the present utility model is that in the prior art, after the heat pipe 2 is inserted into the substrate 1 in the process of manufacturing and installing the heat pipe radiator, the air in the installation hole 11 cannot be completely exhausted, so that the heat pipe 2 cannot be completely attached to the inner wall of the installation hole 11 on the substrate 1. According to the utility model, the exhaust groove 3 is mainly arranged, and the air in the mounting hole 11 on the substrate 1 can be completely exhausted through the exhaust groove 3, so that the heat pipe 2 can be smoothly inserted into the mounting hole 11, and the inserted part of the heat pipe 2 can be completely attached to the mounting hole 11, thereby ensuring that the heat radiation performance of the heat pipe radiator achieves the expected effect.
The technical scheme of the utility model is further specifically described below with reference to the accompanying drawings and a specific embodiment.
As shown in fig. 2, the structure for exhausting air in an inner cavity of a heat pipe radiator provided by the scheme of the utility model includes: a base plate 1, a heat pipe 2 and an exhaust groove 3.
The surface of the base plate 1 is provided with mounting holes 11 through machining, and the heat pipes 2 are mounted in the mounting holes 11 through plugging.
The exhaust groove 3, as a main summary of the present utility model, is configured to communicate the inner space of the mounting hole 11 with the external environment of the substrate 1, so that the original air inside the mounting hole 11 is not compressed by the surface of the heat pipe 2 during the plugging process of the heat pipe 2, but is exhausted to the external environment space of the substrate 1 under the guiding action of the exhaust groove 3, so that the heat pipe 2 and the mounting hole 11 can be closely attached to each other, thereby achieving the optimal heat dissipation effect.
Preferably, in order to make the heat pipe 2 closely fit with the mounting hole 11 as much as possible, so as to achieve the best heat dissipation effect, the outer diameter of the heat pipe 2 is matched with the inner diameter of the mounting hole 11. During installation, the installation holes 11 are heated by a heat-conducting medium such as heat-conducting silica gel, the heat pipes 2 are inserted, and the two are closely attached to each other after cooling.
Preferably, in order to better dissipate heat on the substrate 1, in the heat pipe radiator provided by the utility model, a plurality of mounting holes are formed in the substrate 1, and in order to ensure the mounting efficiency of each heat pipe 2, one air exhaust groove 3 is formed in each mounting hole 11.
Further, the gravity of the heat pipe 2 is used to carry the load by the mounting holes 11, and the contact area with the heat pipe 2 is increased. Therefore, as shown in fig. 2, in the present utility model, each of the mounting holes 11 is distributed on the substrate 1 obliquely upward in the vertical direction, and the mounting holes 11 are designed to be inclined, so that the heat pipe 2 can obtain a larger stress load and heat dissipation area.
Further, as shown in fig. 3 and 4, the air discharge groove 3 is disposed at the bottom of each of the mounting holes 11 in the vertical direction, and the internal air is pressed downward during the insertion of the heat pipe 2, so that the air discharge groove 3 is disposed at the bottom of the mounting hole 11, and the internal air is discharged better.
Preferably, the shape of the heat pipe 2 is not specifically limited, but in order to obtain a larger heat dissipation effect, the shape of the part of the heat pipe 2 inserted into the mounting hole 11 should be linear cylindrical, and the outer diameter matches with the inner diameter of the mounting hole 11, so that the axial center line of the inserted part of the heat pipe 2 and the axial center line of the mounting hole 11 coincide with each other, so that the mutual fit is more firm and tight.
In this embodiment, as shown in fig. 2 and 3, the exhaust groove 3 is formed on the inner wall of the mounting hole 11 by machining, and since the mounting hole 11 is also formed on the substrate 1 by machining, the exhaust groove 3 is only formed on the inner wall of the mounting hole 11, so that when the mounting hole 11 is machined, a machining process can be performed, repeated clamping of the substrate 3 is avoided, and clamping machining of the exhaust groove 3 on the outer surface of the heat pipe 2 is avoided, thereby improving production efficiency.
Also, as shown in fig. 3 and 4, since the mounting hole 11 is generally inclined with respect to the base plate 1, in order to facilitate the processing of the exhaust slot 3, in this embodiment, the center line of the exhaust slot 3 and the axial center line of the mounting hole 11 are parallel to each other, so that the exhaust slot 3 can be processed simultaneously after the processing of the mounting hole 11; at the same time, by arranging the straight line parallel to the mounting hole 11 and the exhaust groove 3, the travel of the air exhaust path can be reduced as far as possible, and the mounting efficiency of the heat pipe 2 can be improved.
Further, as shown in fig. 3, the length of the air discharge groove 3 is kept identical to the depth of the mounting hole 11 in this embodiment. In order to make the original air inside the installation hole 11 be completely discharged, the length of the air discharge groove 3 is extended to the bottom of the installation hole 11 as much as possible, so that the original air inside the installation hole 11 can be discharged through the air discharge groove 3 extended to the bottom of the installation hole 11 when the heat pipe 2 is inserted.
Further, as shown in fig. 3 and 4, in the present embodiment, the opening width of the air vent groove 3 is kept constant, and since the air vent groove 3 is machined, the air vent groove 3 can be designed to be easily machined by keeping the opening width constant.
While the utility model has been described with respect to the above embodiments, it should be noted that modifications can be made by those skilled in the art without departing from the inventive concept, and these are all within the scope of the utility model.
