Description

  The present invention relates to a heat dissipation device that can be molded at a time. In particular, a fixed amount of aluminum ingot billet is formed at a time into a hollow tubular heat dissipation tube base by stamping molding or hydraulic extrusion molding. Such a heat dissipating device relates to a heat dissipating device capable of forming a continuous sealing surface and a plurality of holding grooves of a tube wall by one molding.

  A conventional radiator including a plurality of radiation-type heat radiation fins is configured by combining a plurality of heat radiation fins and a heat radiation nozzle, and the plurality of heat radiation fins are integrally formed on the outer wall of the heat radiation nozzle. Because the heat radiation fins are integrally molded, the manufacturing cost is very high, the thickness of the heat radiation fin body is very thick, and not only the weight load is large, but also the number of heat radiation fins is limited. The heat dissipation effect is not good.

  The above-described conventional heat radiating nozzle of the heat radiator achieves a heat radiating effect by closely adhering a sealing surface at one end to a heat generating part such as a CPU or LED part. Alternatively, one or more heat pipes are combined to improve the heat dissipation performance.

  The shape of the heat radiating nozzle can be in various forms such as a circular shape, a rectangular shape, or other polygonal tubes at the time of implementation. The conventional heat radiating tube base is configured by using a heat radiating tray having a medium hole and fitting and coupling to a hollow tube pedestal.

However, since the heat radiating tray and the hollow tube base are two separate and independent parts, a capillary phenomenon occurs at the joining position of the two parts, and a thermal resistance is generated. Therefore, it is disadvantageous for heat absorption and transmission and adversely affects the heat dissipation effect. In addition, since the heat-dissipating tray and the hollow tube base part are separately manufactured, the cost of the mold is increased, and furthermore, the connection cannot be completed unless an assembly process is provided. That is, overall, the cost is increased, and more process and work time are required at the time of assembly, and the cost performance is low.
The present invention has been made in view of the above-mentioned drawbacks of the conventional heat dissipation nozzle design.

  The problem to be solved by the present invention is to provide a heat dissipating device that can enhance the overall heat dissipating effect and can be molded at once. In this heat radiating device, since the heat radiating nozzle is a part that can be molded once, not only the molding and manufacturing can be simplified, but also the cost can be further reduced. Further, no joining problem occurs, no capillary phenomenon appears, and no thermal resistance occurs, so that heat can be efficiently absorbed and transferred.

  In order to solve the above problems, the present invention provides the following heat dissipation device. In the heat dissipating device of the present invention, a predetermined amount of aluminum ingot billet is formed at a time into a hollow tubular heat dissipating tube base by stamping forming or hydraulic extrusion forming. An integrally continuous sealing surface is formed at the front end or middle position of the heat radiating tube base. A plurality of clamping grooves are formed on the tube wall at a time. Thereby, it couple | bonds circularly so that a several thermal radiation fin may surround. The sealing surface formed at the front end of the heat radiating tube base is provided with a wide surface convex base. Further, an inner concave surface may be further formed on the wide convex table. In addition, an engagement annular groove may be formed on the inner wall of the inner concave surface by lathe processing. Using a sealing surface, a wide convex base, or an inner concave surface, it is installed in close contact with heat-generating parts to provide quick heat absorption and heat dissipation effects. A lamp shade can be coupled to the engagement annular groove.
