Description
Technical field
The present invention relates to a kind of great power LED cooling module that has the heat dissipation metal device of heat pipe.
Background technology
Along with of the continuous popularization of LED light fixture in market, the technical development of LED Lighting Industry, the led module Development Trend becomes each manufacturer and LED technical research person's research direction; Usually adopting light source board to be arranged on LED heat radiation module in the existing high-power LED lamp dispels the heat; Yet poor radiation, the area of dissipation of existing LED heat radiation module are little; If want to implement bigger area of dissipation; Just must enlarge the area of LED heat radiation module, cause the weight of heat sink material and the increase of cost, and the effect that reaches be also unsatisfactory.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, the great power LED cooling module of a kind of radiating effect, area of dissipation is big, cost the is low heat dissipation metal device that has heat pipe is provided.
For realizing above-mentioned purpose, the present invention is a kind of great power LED cooling module that has the heat dissipation metal device of heat pipe, comprises lens subassembly, light source and heat-dissipating aluminium plate; Wherein, lens subassembly comprises lens gland, lens and lens carrier, and lens subassembly is arranged on the top of light source, and lens carrier contacts with the upper surface of light source; Wherein, described light source is fixed on the top of heat-dissipating aluminium plate, and each side and the bottom surface of heat-dissipating aluminium plate all offer some thermovents, and each thermovent all forms heat dissipation channel in heat-dissipating aluminium plate inside, and mutual dislocation is arranged and is interconnected between each heat dissipation channel; Described heat radiation module also includes the module heat pipe, and the heat-dissipating aluminium plate upper surface is offered the groove that matches with the module heat pipe, and the module heat pipe is arranged in this groove, and an end of module heat pipe exceeds heat-dissipating aluminium plate and exposes in air.
Not only improved the effect that heat transmits because light source is set directly at heat-dissipating aluminium plate, also reduced light source board, thereby saved material; Adopt the some heat dissipation channels of heat-dissipating aluminium plate set inside, mutual dislocation and connection between the heat dissipation channel; Each heat dissipation channel all has certain area cavity, and the certain area of dissipation of the heat radiation of LED, this heat-dissipating aluminium plate can utilize the cubic metal characters or patterns structure of a plurality of heat dissipation channels, under the situation with volume, has bigger area width and passage; Improve radiating effect, reduced the quality of heat-dissipating aluminium plate; The module heat pipe is arranged in the groove of heat-dissipating aluminium plate; One end of module heat pipe exceeds heat-dissipating aluminium plate and exposes in air; Adopt design like this, can the heat of heat-dissipating aluminium plate be passed, can the port of module heat pipe and lamp outer casing etc. be linked to each other; Make lamp outer casing form a radiating surface, increased area of dissipation, improved heat dispersion.
Wherein, the bottom surface of described light source is embedded in the heat-dissipating aluminium plate, and the upper surface of light source exposes out.Adopt the mode of this embedded type to make the heat of light source to be delivered to fast on the heat-dissipating aluminium plate, dispel the heat through heat-dissipating aluminium plate.
Wherein, the position offered of the groove of said cooperation module heat pipe be positioned at light source under.Adopt such design to be because the maximum place of heat is near the light source, the below that the module heat pipe is arranged on light source can effectively pass heat.
Wherein, offer seal groove on described lens carrier and the end face that light source contacts, be provided with sealing ring in the seal groove.Be provided with hermetically-sealed construction and can prevent the influence of water smoke light source.
Wherein, described thermovent be shaped as circle, the diameter of each thermovent is arranged in the 3-5mm.
Adopt the diameter of circular thermovent and thermovent different, the thermovent diameter is arranged in the 3-5mm interval, can be increased in the gross area of thermovent under the equal aluminium sheet area, has increased area of dissipation and has improved radiating effect, has reduced the quality of heat-dissipating aluminium plate.
