In one embodiment, the heat dissipation fins 128 are disposed at regular intervals in the circumferential direction of the outer surface of the body portion 122 provided in a cylindrical shape. That is, the heat dissipation fins 128 are formed integrally with the body portion 122. Of course, the heat dissipation fin 128 is provided of an aluminum material integrally formed with the body portion 122. Thus, the heat dissipation fin 128 and the body portion 122 are integrally formed, so that heat exchange of heat transferred to the body portion 122 is efficiently performed by the heat dissipation fin 128.

The sealing cap 130 is connected to one side of the heat pipe 120. That is, the sealing cap 130 is disposed on one side of the heat pipe 120 opposed to the sealing portion 140, which will be described later, to block the air inflow of the heat pipe 120.

Next, the sealing unit 140 includes a sealing body 142 and the discharge passage 144. The sealing part 140 closes the opening of the heat pipe 120, that is, air is introduced into the hollow part 124 formed inside the body part 122 by being screwed into the coupling hole 126 of the heat pipe 120. Block it from becoming

As described above, the sealing body 142 blocks air from entering the hollow portion 124 of the heat pipe 120 and discharges the air from the hollow portion 124 to the outside of the heat pipe 120. Play a role.

The discharge passage 144 is formed through the sealing body 142 along the coupling direction of the sealing body 142. The discharge passage 144 communicates with the vacuum passage 153 of the vacuum coupling unit 150 to be described later to guide discharge of air remaining in the hollow portion 124 of the heat pipe 120.

Meanwhile, an air inhaler (not shown) is used in the present invention to discharge the air remaining in the hollow portion 124 of the heat pipe 120 to make the hollow portion 124 in a vacuum state.

In order to make the hollow part 124 of the heat pipe 120 into a vacuum state, first, the opening / closing control member 159 is rotated to move the opening / closing member 157 to an open position to open the discharge passage 144. Then, the air intake is connected to the air suction passage 155 in communication with the vacuum passage 153. After operating the air inhaler to make the hollow portion 124 of the heat pipe 120 in a vacuum state, the opening / closing control member 159 is rotated and the opening / closing member 157 moves to the closed position to close the discharge passage 144. Let's do it. When the hollow part 124 of the heat pipe 120 is in a vacuum state, the air intake is disconnected.

The heat transfer reinforcing member 170 is interposed between the heat pipe 120 and the sealing part 140. The heat transfer reinforcing member 170 is an elastic body, and is formed of a polymer material, which is a heat transfer body, to transfer heat transferred to the sealing unit 140 to the heat pipe 120.

The heat transfer body 320 supports the plurality of heat pipe assemblies 100. Heat transfer unit body 320 is an embodiment of the present invention, because one can be transferred to only one side of the heat pipe assembly 100 is provided, but the heat transfer or heat pipe assembly to both sides of the heat pipe assembly 100 Two may be provided for supporting both sides of the 100.

The hot water flow passage 340 is formed inside the heat transfer body 320 to allow hot water, which is a heat source for supplying heat to the heat pipe assembly 100. Here, the hot water flow passage 340 is hot water heated to a high temperature from the outside. The hot water flowing into the hot water flow passage 340 transfers heat to the heat pipe assembly 100.

Here, the fastening hole 350 guides the screw coupling of the heat pipe assembly 100 and the heat transfer part 300. That is, since the heat pipe assembly 100 and the heat transfer part 300 are different from each other in aluminum and copper, difficulty of a coupling method such as welding is generated. Thus, as shown in the present invention, the coupling of the heat pipe assembly 100 and the heat transfer part 300 using the fastening hole 350 can be secured by the ease of coupling.

The connection member 360 may be made of an aluminum material such as the heat pipe assembly 100, or a ceramic material having high heat conduction efficiency may be used.

Accordingly, the heat pipes having the heat dissipation fins integrally formed may maintain a vacuum state by using a sealed part and a vacuum fastening part to improve heat transfer efficiency, thereby improving product performance.

In addition, the heat pipe assembly may be made of aluminum to improve heat transfer efficiency.

In addition, by combining the heat pipe assembly made of aluminum material and the heat transfer part made of copper through screw coupling, it is possible to reduce the complexity and assembly time of the assembly process of the heat pipe assembly and the heat transfer part.
