Problems solved by technology
[0007] However, the known heat pipe radiator must use the solder layer as the medium connecting the heat pipe and the heat conduction block, thus increasing the material cost
In addition, the welding of the heat pipe and the heat conduction block needs to be heated and melted to oxidize the surface of the copper heat pipe to form black copper oxide. Therefore, it is necessary to increase the manufacturing process to restore its color, thereby increasing the manufacturing cost and time cost.
In addition, the decrease in thermal conductivity caused by the thermal resistance caused by solder is also a problem that cannot be underestimated.
Finally, since the thermal conductivity of the heat pipe is much greater than that of the heat conduction block, but the heat pipe is not directly attached to the object to be dissipated, the working efficiency is limited, which makes the improvement of heat conduction efficiency limited.

The invention relates to a manufacture method for jointing heat pipe and radiator that needs not third party medium. It is formed by embedding U shaped heat pipe in heat conductive block. The block is formed by rectangular plate and a upper cover. Containing flutes corresponding to heat absorbing end of heat pipe is set on base, and through holes corresponding to condensing end of heat pipe are set on upper cover. The heat absorbing end and the bottom of heat conductive block would be processed to plane.
Description
technical field [0001] The invention relates to a radiator and a manufacturing method thereof, in particular to a heat pipe radiator in which a heat pipe can directly contact a heat source and a manufacturing method thereof. Background technique [0002] When using electrical or electronic products such as the CPU of a personal computer, laser light emitting diodes or power transistors, heat energy is generated. In recent years, the heat energy generated by electronic components has been increasing day by day, and heat dissipation technology has thus become a key technology in the electrical or electronic industry. There are two typical cooling methods for electronic or electrical products, one is to directly install a cooling body on the electronic heating component, and the other is to use a fan to reduce the temperature of the housing loaded with electronic components. [0003] The cooling body installed on the electronic component is usually a flat base made of a materi...
