Description
Technical field
This utility model relates to scialyscope technical field。
Background technology
Scialyscope bulb in the course of the work can produce substantial amounts of heat, the energy of bulb is except a part becomes luminous energy, major part distributes in scialyscope with the form of heat, and these heats, as left not in time, can have a strong impact on the normal work and use life-span of scialyscope。Therefore in scialyscope, being designed with cooling mechanism, common cooling mechanism adopts plate fin type radiator, then coordinates blower fan to force to cool down to bulb。For ensureing that radiating effect is frequently with powerful blower fan, so will result in complete machine operating noise big, and radiating effect is also not ideal。
Prior art exists a kind of projector lamp, including bulb, heat abstractor, aerofoil fan；Described bulb is arranged on heat abstractor, and heat abstractor has heat dissipation channel, and aerofoil fan is arranged on bulb tail, is blown into cold air in heat dissipation channel, discharges after heat dissipation channel；Described heat abstractor is multiple plate fin type radiators being arranged in an axially parallel mode, and forms heat dissipation channel, be provided with multiple turbulence columns in heat dissipation channel between described plate fin type radiator adjacent fins。The program arranges turbulence columns in the heat dissipation channel of plate fin type radiator, the turbulence level that air in heat dissipation channel flows is strengthened than common plate fin radiator, the flow velocity of fin near wall is also greatly increased, thus the convection transfer rate increased between fin wall and air increases, improve heat exchange efficiency。But, the program suffers from the drawback that, although turbulence columns can increase the turbulence level of air to increase flow velocity, but wind also having certain barrier effect, tapering into even calm away from wind speed in the heat dissipation channel at blower fan place, so have impact on the effect of heat radiation。
Utility model content
This utility model is intended to provide a kind of wind speed made in whole heat dissipation channel uniform, the twayblade radiator for projector of effective improving radiating effect。
The twayblade radiator for projector in this programme, including air-cooler, heat dissipation tank, several heat dissipation channels formed by plate wing it are provided with in described heat dissipation tank, this heat dissipation channel inner arm is provided with several turbulence columns, the air inlet of heat dissipation channel and the outlet of air-cooler communicate, the air outlet of heat dissipation channel leads to the external world, and the stage casing of described plate wing disconnects and makes passage separate formation disconnection space, is provided with some being arranged on and the helical blade in air-cooler rotating shaft in this disconnection space。
Beneficial effect: this radiator is arranged on the back side of projector lamp, when projector runs, light fixture generates heat, heat rests in heat dissipation tank, now starting air-cooler, cold air enters in heat dissipation channel, is upset by the turbulence columns in heat dissipation channel, arrive helical blade place, air-cooler drives helical blade to rotate, and helical blade rotates wind is again regular, entering in heat dissipation channel by wind, and then upset through air outlet eliminating by turbulence columns, take away the heat in heat dissipation tank。Compared to the prior art such scheme, is provided with helical blade inside heat dissipation tank, carries out again regular to wind, it is ensured that the exit wind speed of heat dissipation channel is still high, good heat dissipation effect。
Further, the quantity of described helical blade is 4, improves the helical blade regular ability to wind。
Further, the turbulence columns in same heat dissipation channel is uniformly arranged, and pin-fin diameter is D, and between turbulence columns, spacing is 5-10D。。The disorderly degree and the wind speed that make wind are balanced。
Further, between the described turbulence columns in same heat dissipation channel, spacing changes between 5-10D, is smaller than near air inlet turbulence columns spacing near air outlet place turbulence columns。More near near air outlet and distance projector light fixture, so increasing the disorderly coefficient of wind, improve heat exchange degree, radiating effect is better。
Further, described helical blade is aluminum sheet, and aluminum sheet is lightweight, it is easier to be rotated by wind。
Accompanying drawing explanation
Fig. 1 is this utility model structural representation for the twayblade radiator embodiment of projector。
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: heat dissipation tank 1, heat dissipation channel 11, turbulence columns 111, air inlet 112, air outlet 113, helical blade 2, air-cooler 3。
Embodiment is substantially as shown in Figure 1:
The twayblade radiator for projector in this programme, including air-cooler 3, heat dissipation tank 1, it is welded with plate wing in heat dissipation tank 1 and forms several heat dissipation channels 11, the air inlet 112 of heat dissipation channel 11 is relative with air-cooler 3, the air outlet 113 of heat dissipation channel 11 leads to the external world, and this passage inner arm is provided with some turbulence columns 111。
Being provided with rotating shaft in heat dissipation tank 1, the stage casing of plate wing disconnects and makes passage separate formation disconnection space, is provided with helical blade 2 in this disconnection space in the rotating shaft of air-cooler, and the quantity of helical blade 2 is 4, improves the helical blade 2 regular ability to wind。
Turbulence columns 111 in same heat dissipation channel 11 is uniformly arranged, and between turbulence columns 111, spacing is 5-10D, D is turbulence columns 111 diameter。The disorderly coefficient wind speed making wind is balanced。Between described turbulence columns 111 in same heat dissipation channel 11, spacing changes between 5-10D, less near air outlet 113 place turbulence columns 111 spacing, bigger near air inlet 112 place turbulence columns 111 spacing。More near near air outlet 113 and distance projector light fixture, so increasing the disorderly coefficient of wind, improve heat exchange degree, radiating effect is better。Helical blade 2 is aluminum sheet, and aluminum sheet is lightweight, it is easier to be rotated by wind。
Operation principle: this radiator is arranged on the back side of projector lamp, when projector runs, light fixture generates heat, heat rests in heat dissipation tank 1, air-cooler 3 starts simultaneously, cold air enters and spreads in the passage of heat, upset by the turbulence columns 111 in heat dissipation channel 11, arrive helical blade 2 place, cold wind drives helical blade 2 to rotate, and helical blade 2 rotates wind again regular, being entered by wind in heat dissipation channel 11, and then upset get rid of through air outlet 113 by turbulence columns 111, take away the heat in heat dissipation tank 1。
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this。Should be understood that; for a person skilled in the art, under the premise without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented。The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim。
