Heat dissipation module of LED tunnel lamp

Abstract

The invention belongs to the technical field of heat dissipation modules and particularly relates to a heat dissipation module of an LED tunnel lamp. The heat dissipation module comprises a rectangular bottom plate, a heat-sink horizontal heat dissipation fin assembly is arranged on the upper sides of the middle parts of the longer sides of the bottom plate and comprises a set of heat-sink horizontal heat dissipation fins overlapped upwards in the vertical direction, a vertical air splitting blade is arranged in a gap between every two adjacent heat-sink horizontal heat dissipation fins, and two longer sides of each heat-sink horizontal heat dissipation fins extend outwards on the corresponding vertical air splitting blades for forming symmetric smooth arc-shaped protrusions; a heat-sink vertical heat dissipation fin assembly is arranged at the upper part of the heat-sink horizontal heat dissipation fin assembly and comprises a set of heat-sink vertical heat dissipation fins; a heat-sink horizontal heat dissipation fin air channel shell is arranged outside the heat-sink horizontal heat dissipation fins in a sleeving mode and is provided with an opening, a fan cavity is formed in each of the two ends of the heat-sink horizontal heat dissipation fin air channel shell, a fan is arranged inside each fan cavity, and a heat dissipation assembly air inlet hole is formed in the outer side of each fan cavity. The heat dissipation module has the advantages of being good in heat dissipation effect and long in service life.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation modules, and in particular relates to a heat dissipation module of an LED tunnel lamp. Background technique [0002] LED has a series of advantages such as small size, impact resistance, long life, low power consumption, cold light emission and no mercury pollution. It is widely used in various indications, displays, decorations, backlights, general lighting and urban night scenes. There are still some shortcomings in the process of using LEDs. At present, most of the input power of LEDs is still released in the form of heat energy. If the heat is not discharged in time, the junction temperature of the LED chip will be too high, which will affect the luminous efficiency and service life. And a series of problems, and at this stage LED technology cannot completely avoid heat generation, and the material of the heat dissipation structure of LED lamps is not available at the current stage wi...
