Closed heat dissipating piece

Abstract

The invention discloses a closed heat dissipating piece. The closed heat dissipating piece comprises an upper surface for absorbing heat and supporting an external part, an outer side surface for dissipating heat outside, and an inner side surface arranged in the center of the heat dissipating piece; the inner side surface and the upper surface are combined to form an air way for enabling air to circulate; the edge of the upper surface is connected with the outer side surface; a through hole is formed in the center of the upper surface; the through hole is inwards recessed, and is connected with the inner side surface; the outer side surface and the inner side surface both surround annular structures with closed side walls; the other side opposite to the upper surface is an open lower surface consisting of the outer side surface and the inner side surface; and the closed heat dissipating piece is totally a hollow three-dimensional ring with opened bottom. The closed heat dissipating piece is applied to the internal of an LED lamp as a radiator to build a cold and hot air convection channel, so that the heat can be effectively dissipated, the internal heat accumulation is reduced, and the LED lamp life is prolonged.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of LED lamps, in particular to a closed heat dissipation part. Background technique [0002] At present, most of the radiators of LED lamps adopt finned design, but finned radiators face two problems. One is that they cannot be installed inside small LED lamps due to structural reasons. Small LEDs use metal shells to expose or directly cancel the heat dissipation design. Second, most lamps are only equipped with finned radiators without considering the problem of heat dissipation and convection. The structure of the lamp itself cannot form effective convection with the outside world, resulting in poor heat dissipation. The internal LED lamp beads are in a high temperature state for a long time. Shortened service life. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a closed heat dissipation element, which can bu...
