Abstract
The utility model relates to a digital television modulator, in particular to a radiating structure for a digital television modulator. The radiating structure comprises a casing and an internal circuit board and a radiating plate which are arranged in the casing, wherein the casing comprises a top plate, a bottom plate, a front panel, a rear panel, a left side plate and a right side plate; the left side plate is provided with one or a plurality of inlet air duct fans; the right side plate is provided with one or a plurality of outlet air duct fans; a left side duct extracts cold current into a case; the cold current can transversely pass through the whole case; and a right side duct sends hot current outside the case. The fans on the left side and the right side of the digital television modulator can be positioned on the main flowing path of the internal radiating airflow to eliminate heat accumulation; and the radiating manner of the extractor fans on two sides enables the efficiency of the wind volume to be high to meet the requirement of large heat irradiation capacity.
Description
Technical field
The utility model relates to a kind of digital television modulator, especially the radiator structure of digital television modulator inside.
Background technology
Existing digital television modulator is often only installed fan in the equipment rear end, because spatial limitation, fan must be avoided the out splice going splice of inner high-power RF module, thereby makes the latter can not be on the path of mainly flowing through of internal heat dissipating air-flow, and heat build-up is obvious.And what the radiating mode that one-sided extractor fan is only arranged made fan crosses the air quantity inefficiency, can't satisfy big heat dissipation capacity demand.And the life-span affected by heat of electronic devices and components is obvious, and heat radiation is not smooth to damage the inner components and parts life-span of digital television modulator easily, thereby influences the stability that complete machine uses.
Summary of the invention
The utility model provides a kind of radiating efficiency high digital television modulator radiator structure.
To achieve these goals, the utility model adopts following technical scheme:
Comprise shell and internal circuit board thereof and fin, described shell comprises top board, base plate, front panel, rear board, left plate and right plate, its improvement is: described left plate is provided with one or more air intake ducted fans, described right plate is provided with one or more air-out ducted fans, described left side duct is with in the cold airflow suction cabinet, laterally, thermal current is sent to outside the cabinet by the right side duct by behind the whole cabinet.
Preferably, described left side air intake ducted fan power is less than right side air-out ducted fan power.
Preferably, described left plate is provided with 4 air intake ducted fans, and described right plate is provided with 4 air-out ducted fans.
Preferably, described cabinet inside board structure of circuit and fin are the horizontal mode installation.
Digital television modulator of the present utility model makes fan can be on the path of mainly flowing through of internal heat dissipating air-flow at equipment left and right sides fan, has eliminated heat build-up.And what the radiating mode of both sides extractor fan made fan crosses air quantity efficient height, can satisfy big heat dissipation capacity demand.
Description of drawings
Fig. 1 is the left panel structural representation of the utility model embodiment;
Fig. 2 be the utility model embodiment the panel construction schematic diagram arranged;
Fig. 3 is the stereogram of the utility model embodiment.
The utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
As shown in Figure 1, it comprises shell and internal circuit board and fin, described shell comprises top board 1, base plate (not shown), front panel 2, rear board (not shown), left plate 3 and right plate 4, described left plate 3 is provided with one or more air intake ducted fans 31, described right plate 4 is provided with one or more air-out ducted fans 41, described left side ducted fan 31 is with in the cold airflow suction cabinet, laterally by behind the whole cabinet, thermal current is sent to outside the cabinet by right side ducted fan 41.Left plate described in the present embodiment is provided with 4 air intake ducted fans, and described right plate is provided with 4 air-out ducted fans.
In order to improve radiating efficiency, the described left side of present embodiment air intake ducted fan 31 power are less than right side air-out ducted fan 41 power, thereby making whole cabinet inside atmospheric pressure be negative pressure distributes, then all caloric values are than the large part louvre, all assist and suck cold air, help heat radiation, guarantee the accumulation of cabinet inside empty calory.，
In order to make the cabinet inside device not produce the brattice effect to crossflow, reduced the air-flow mediation, described cabinet inside board structure of circuit and fin are horizontal mode to be installed, and has further improved the efficient of internal convection.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
