Description
Technical field
The utility model relates to a kind of illuminating module, particularly the illuminating module of integrated LED bottom a kind of heat pipe.
Background technology
Along with the continuous increase of LED device power, it is particularly outstanding that heat dissipation problem becomes.At present, most electric energy of great power LED can be converted to heat energy.These heat energy will make the LED junction temperature too high, and then influence product life cycle, luminous efficiency, stability if can't derive.Traditional led light source generally uses the method for heat-conducting silicone grease or solder to be mounted on the substrate, and then with the method for heat-conducting silicone grease or solder it is linked to each other with radiator substrate.This encapsulating structure thermal resistance is bigger, and if heat-conducting silicone grease apply inhomogeneously, can make the chip local temperature too high, thereby influence the life-span of led chip.
Summary of the invention
In order to solve prior art problems, the utility model provides the illuminating module of a kind of heat pipe bottom integrated LED, it has not only removed the thermal resistance of articulamentum between substrate and the radiator, formed dead-weight heat pipe has also improved the conduction velocity of heat in radiator greatly, and make the fin Temperature Distribution more even, improved the radiating efficiency of radiator.
The technical scheme that the utility model adopts is as follows:
The illuminating module of a kind of heat pipe bottom integrated LED, comprise tubular cooler, the tubular cooler upper end is provided with the last end cover that includes perfusing hole, on the described perfusing hole of going up on the end cover sealing bolt is set, described tubular cooler lower end is provided with the lower seal end cap, described lower seal end cap is provided with led chip, is filled with working medium in the described tubular cooler.
The two ends up and down of tubular cooler all are provided with step, and it is used for end cover and lower seal end cap in welding or the sealing-in.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
Not only removed the thermal resistance of articulamentum between substrate and the radiator, formed dead-weight heat pipe has also improved the conduction velocity of heat in radiator greatly, and makes the fin Temperature Distribution more even, has improved the radiating efficiency of radiator.

The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
With reference to Fig. 1-5, it is thermal component that the utility model adopts the aluminum tubular cooler, and the last end cover 2 that will contain perfusing hole 8 links together with radiator 3 with the lower seal end cap 5 that led chip 6 is housed, and concrete structure comprises:
1, tubular cooler 3 centers are cavity, and cavity inside can have fin also can not have, and the step 7 with the welding of upper-lower seal end cap or sealing-in is arranged at the top of radiator and bottom.
2, the last end cover 2 that contains perfusing hole 8 is useful on the aperture 8 that pours into liquid refrigerant in the middle of the top cover labyrinth plate 2 of aluminum.
3, the lower seal end cap 5 of led chip 6 is housed, the mode of led chip 6 usefulness heat-conducting silicone greases or solder is installed in the front of lower seal end cap 5.
4, the syndeton of upper-lower seal cover plate and tubular cooler is specifically:
The last end cover 2 that will contain perfusing hole links together with tubular cooler 3 with the lower seal end cap 5 that led chip 6 is housed, this method of attachment can be the less Laser Welding in heat affected area, electron beam welding etc., also can be that mechanical seal connects, as bonding, flange connection etc., adopt the method for attachment of Laser Welding in the present embodiment, from the fill orifice of top cover labyrinth plate, inject liquid refrigerant 9, vacuumize again then and seal, choose bolt in the present embodiment and seal.Like this, the mid portion of this integrated module has just formed a dead-weight heat pipe, and the lower seal end cap is the hot junction of heat pipe, and the heat pipe cold junction relies on the fin heat radiation.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
