Abstract
The invention discloses a projector lamp, including a bulb, a heat radiation device and an axial fan. The bulb is arranged on the heat radiation device which has heat radiation channels, the axial fan is arranged at the tail of the bulb and blows cold air into the heat radiation channels, and the cold air is discharged after passing through the heat radiation channels; and the heat radiation device includes a plurality of plate-fin type radiators arranged parallelly in an axial direction, the hear radiation channels are formed between adjacent fins of the plate-fin type radiators, and a plurality of turbulent flow columns are arranged inside the heat radiation channels. According to the projector lamp provided by the invention, the turbulent flow columns are arranged inside the heat radiation channels of the plate-fin type radiators, so that the turbulence degree of air flow inside the heat radiation channels is enhanced compared with a common plate-fin type radiator, and flow velocity near wall faces of the fins is also greatly increased, thereby increasing the coefficient of convective heat exchange between the wall faces of the fins and air, and improving heat exchange efficiency. Radiators of the same size require relatively small fan power under the same working condition, thereby reducing cost of the radiators, and working noise when the projector lamp works can also be reduced.
Description
Technical field
The invention belongs to projector's technical field, particularly relate to a kind of projector lamp with high efficiency and heat radiation ability.
Background technology
Projector in the course of the work bulb can produce a large amount of heats, the energy of bulb is except a part becomes luminous energy, major part is distributed in projector 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 projector.Therefore in projector, be all provided with cooling mechanism, common cooling mechanism adopts plate fin type radiator, then coordinates blower fan to force to cool to bulb.For ensureing that radiating effect often adopts powerful blower fan, complete machine operating noise will be caused so large, and radiating effect is also not ideal.
Summary of the invention
The object of the invention is to provide a kind of projector lamp with high efficiency and heat radiation ability for the defect of prior art.
The present invention for achieving the above object, adopts following technical scheme:
A kind of projector lamp, comprises bulb, heat abstractor, aerofoil fan; Described bulb is arranged on described heat abstractor, and described heat abstractor has heat dissipation channel, and described aerofoil fan is arranged on described bulb tail, is blown into cold air, discharges after heat dissipation channel in heat dissipation channel; It is characterized in that: described heat abstractor is the plate fin type radiator that multiple axis be arranged in parallel, form heat dissipation channel between described plate fin type radiator adjacent fins, in described heat dissipation channel, be provided with multiple turbulence columns.
It is further characterized in that: the described turbulence columns in adjacent heat radiation passage is crisscross arranged.
A kind of form: the described turbulence columns in same heat dissipation channel is evenly arranged, and between described turbulence columns, spacing is 5-10D, D is pin-fin diameter.
Another kind of form: between the described turbulence columns in same heat dissipation channel, spacing changes between 5-10D, less near bulb place turbulence columns spacing, larger away from bulb place turbulence columns spacing.
Preferred: described heat abstractor material is aluminium.
The present invention by arranging 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 also increases greatly, thus the convection transfer rate increased between fin wall and air increases, improve heat exchange efficiency.Under the heating radiator and same operating mode of same size, required fan power is less, thus reduces the cost of heating radiator, can also reduce operating noise during projector lamp work simultaneously.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
A projector lamp as shown in Figure 1, comprises bulb 1, aluminum plate-fin type heat abstractor 2, aerofoil fan 3; Described bulb 1 is arranged on described heat abstractor 2, forms heat dissipation channel between described adjacent fins 21, is provided with multiple turbulence columns 22 in described heat dissipation channel.Described aerofoil fan 3 is arranged on described bulb 1 afterbody, is blown into cold air, discharges after heat dissipation channel in heat dissipation channel.Owing to arranging turbulence columns 22 in the heat dissipation channel of plate-fin heat abstractor 2, the turbulence level that air in heat dissipation channel flows is strengthened than common plate fin radiator, the flow velocity of fin 21 near wall also increases greatly, thus the convection transfer rate increased between fin 21 wall and air increases, improve heat exchange efficiency.
Described turbulence columns 22 in adjacent heat radiation passage is crisscross arranged.The turbulence columns 22 be crisscross arranged can make the turbulent flow in different heat dissipation channel mutually stagger, thus improves radiating efficiency.
When the heat flow density of thermal source is uniformly distributed, the described turbulence columns 22 in same heat dissipation channel can evenly be arranged, and between described turbulence columns 22, spacing is 5-10D, D is pin-fin diameter.
When thermal source is relatively concentrated: between the described turbulence columns 22 in same heat dissipation channel, spacing changes between 5-10D, less near bulb 1 place turbulence columns 22 spacing, larger away from bulb 1 place turbulence columns 22 spacing.
Above embodiment is the preferred embodiment for the present invention, and under the premise without departing from the principles of the invention, can also make suitably change and modify, these changes and modification also should be considered as protection scope of the present invention.
