Benefits of technology

The present invention aims to provide a heat dissipation assembly with reduced production cost and enhanced all-directional convection capability. This assembly includes a base element with a slot, a heat dissipation element embedded into the slot, and a filler element to force the heat dissipation element into the slot. The gaps between the heat dissipation elements provide improved convection effect.

Problems solved by technology

The above process requires special apparatus (e.g., the vacuum oven), in addition to its long operating time and delicate control, thereby a high production cost.
Furthermore, the process also produces waste that would be harmful to the environment.
However, for the heat dissipation assembly A just described, the major drawback is that the tube A2 actually would block air flow and the convection would be limited to the rims of the fins A3.

first embodiment

[0023]As shown in FIGS. 2 and 3, a heat dissipation assembly 1 according to the present invention contains at least a base element 11, at least a heat dissipation element 12, and at least a filler element 13. In the present embodiment, there are two base elements 11 and, as the two are identical, only one is described as follows. The base element 11 is radially configured a number of slots 111 along its circumference. Each slot 111 is embedded with a heat dissipation element 12 and therefore the number of slots 12 determines the number of the heat dissipation elements 12. Each heat dissipation element 12 contains two identically shaped pieces arranged in parallel. The two pieces are bended along their inner edge to form perpendicular sections 121, respectively. The filler elements 13 have the same width as that of each slot 111. The number of the filler elements 13 is the same as or a multiple of the number of the number of slots 111. In the present embodiment, there are 15 slots. T...

second embodiment

[0026]the present invention as shown in FIG. 5 has rather similar structure as that of the previous embodiment. The difference lies in that there are 30 filler elements 13, each for plugging into a slot 111. Additionally, there is a lamp base 18 jointed to the lower base element 11. The lighting element 17 is electrically connected to the lamp base 18 through electrical cords extended from the bottom side of the upper base element 11, and through the center of the lower base element 11.

[0027]In addition to using the filler elements 13, the heat dissipation elements can be fixedly embedded in the slots 111 by means such as welding and adhesion.

Abstract

The heat dissipation assembly contains at least a base element having at least a slot; at least a heat dissipation element embedded into the slot; and at least a filler element for forcing the fixed embedment of the heat dissipation element into the slot. The gaps between the heat dissipation elements provide enhanced convection effect.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention is generally related to heat dissipation, and more particular to a heat dissipation assembly applicable to lamps.DESCRIPTION OF THE PRIOR ART[0002]Heat pipes are commonly applied to electronic appliances due to their superior thermal conductivity Conventionally, as disclosed by Taiwan Patent No. 449514, solder is coated on the interface between a heat pipe and the fins jointed to the heat pipe. The assembly is then placed and heated inside a vacuum oven. The solder is melted and permeate the interface due to the capillary effect. The solder is then solidified and the fins are welded to the heat pipe. The above process requires special apparatus (e.g., the vacuum oven), in addition to its long operating time and delicate control, thereby a high production cost. Furthermore, the process also produces waste that would be harmful to the environment.[0003]Another way to couple the heat pipe and the fins is by tightening. As show...
