Description
- This application claims priority of Chinese Application No. 201110110519.1, filed on Apr. 27, 2011.
- 1. Field of the Invention
- The invention relates to a heat dissipating device, more particularly to a heat dissipating device that is easy to assemble.
- 2. Description of the Related Art
- A light-emitting diode (LED) has many advantages including low power consumption, high efficiency, excellent energy conservation, long life span and very low pollution generation, and thus has been utilized widely. It is common to dispose a plurality of LEDs in one lamp for lighting. Due to the temperature rise during the operation of the LED, assembling multiple LEDs in a lamp may easily produce and accumulate a large amount of heat, which, if not dissipated in time, will arise in problems such as color rendering problem, diminished brightness, shortened life span and malfunction. Therefore, heat dissipation has always been a crucial issue.
- A heat dissipating module disclosed in Taiwanese Utility Model no. M395787 includes a plurality of heat dissipating fins. Each of the heat dissipating fins includes an engaging portion formed with a protrusion and a groove. The heat dissipating module is assembled by engaging the protrusion of each of the heat dissipating fins to the groove of the engaging portion of a corresponding adjacent one of the heat dissipating fins.
- While the heat dissipating module mentioned above is able to achieve a desired heat dissipating effect, the manufacture of such heat dissipating fins requires complicated processing and additional costs. Moreover, assembly using the protrusions and grooves of the heat dissipating fins may raise questions regarding stability of the heat dissipating module, since each of the heat dissipating fins is a thin plate itself, let along the protrusions and grooves disposed on the thin heat dissipating fins. Lack of caution during the assembly procedure may impair the engaging function of the protrusions and grooves, rendering the heat dissipating base unworkable.
- Therefore, the object of the present invention is to provide a heat dissipating device that is easy to assemble.
- Accordingly, a heat dissipating device of the present invention comprises a tubular body and a plurality of heat dissipating fins. The tubular body has a first open end, and each of the heat dissipating fins has a fin body and a first engaging portion. For each of the heat dissipating fins, the first engaging portion is formed on the fin body for engaging the first open end of the tubular body in a manner that the heat dissipating fins are disposed to radiate from and to surround the tubular body. The first engaging portion includes a first extension section and a first hook. The first extension section is bent from the fin body, and the first hook extends from the first extension section for hooking onto the tubular body at the first open end.
