[Prior art]

 As is well known, high heat is generated during the operation of the CPU of a computer, and the higher the operation speed, the higher the wattage of the drive power and the higher the temperature generated. If the CPU temperature is too high, its operation will be affected and the computer may shut down. For this reason, if the heat dissipation problem cannot be solved, the operating speed of the CPU is limited, and the speed of the CPU cannot be further increased. The well-known computer CPU radiator has a main structure that is an extension of the traditional radiator, that is, a number of radiating fins are provided extending on one aluminum plate, and this aluminum plate is attached to the upper end of the CPU. The heat of the CPU is absorbed and transmitted to the radiating fins, and the heat exchange between the radiating fins and the cool air is further progressed to lower the temperature of the CPU.

When the above-mentioned known computer CPU radiator is used in a desktop computer, the main body of the desktop computer is relatively large, so that there is a relatively large space inside the radiator. Can increase the speed of heat exchange between the fins and the cold air and lower the temperature of the CPU. However, in the case of notebook PCs that are emphasized to be light, thin and easy to carry, the mounting of the fan increases the thickness, which is contrary to the design philosophy of the notebook PC. Speeding up was not an ideal solution for laptops.

[0004] The above-described method of mounting the fan cannot solve the heat radiation problem of the CPU of all the computers, and the main cause is that the space is limited. If this can be done, this problem will be solved. As a solution to this problem, computer manufacturers have already adopted a method of conducting heat to the outside by connecting a radiator to a computer case made of aluminum magnesium alloy. However, test results show that the temperature at which it is reduced is fairly finite, and the problem is still that heat cannot be transferred quickly and efficiently to computer cases made of aluminum magnesium alloy. As can be seen from this, the heat conduction problem is one of the most important problems in the research and development technology of the computer CPU radiator.

In the heat transfer technology, a so-called heat pipe, which is a heat superconductor, has a heat transfer efficiency of 10,000 W / m 2 ^. K, and more than 300 times that of copper (copper 360W / m. ^K) is, and its structure is simple, light weight, high reliability, is the essential element In the sanitary及beauty spacecraft . For this reason, the present inventor combined the heat pipe with the radiator during the research and development process to form an integrated heat pipe and made it into a heat pipe with extremely high heat conduction efficiency, effectively connecting and operating the radiator, thereby increasing the heat conduction efficiency of the radiator .

As shown in FIGS. 1 and 2, the known heat pipe radiator 10 is composed of a plurality of radiating fins 11 and a bottom plate 12, of which the radiating fins 11 are provided on the bottom plate 12. The bottom plate 12 is placed on the object to be radiated, and a hollow tubular through-hole 13 is provided in the center thereof. The through-hole 13 is sealed by inserting plugs 14 at both ends. Thereby, a closed space is formed, a capillary structure and a condensate flow are provided in the closed space, and the bottom plate forms a heat pipe structure.

After the bottom plate 12 absorbs the heat source of the object to be radiated, that is, conducts the heat to the heat radiating fin 11 directly at a very rapid speed, and the heat radiating fin 11 radiates heat to quickly absorb the heat of the object to be radiated. Achieve the purpose of conduction.

A plug is fixed to the above-mentioned heat pipe type radiator in a tightly combined manner. At the time of initial use, a closed space of a heat pipe structure is formed in the through hole, but the plug is tightly pressed in. Due to dimensional errors, the degree of sealing of the enclosed space becomes insufficient due to dimensional errors, and the plug is prone to fatigue under long-term cooling and heat exchange, destroying the sealed state in the through hole, The function of heat absorption and conduction decreased.

Further, another method of fixing the plug of the heat pipe type radiator is to fix the plug to both ends of the through hole of the bottom plate by a screw method to seal the inside of the through hole. However, this screw fixing method is applied only to a circular through hole, and thus has a drawback that the working range is extremely limited. In addition, screws must be provided in both the through-holes and plugs of the heat pipe radiator and they must be connected to each other, resulting in slow processing speed and increased manufacturing costs.

The inventor of the present invention has been made to solve the problem of breaking the hermetically sealed state in the through hole according to the known technique.
