The utility model content
The purpose of this utility model is to provide a kind of numeric display unit, and its internal heating element separates installation with display screen component, thereby reduces the heat of heater element generation to the impact of display screen component, improves radiating effect.
For realizing above utility model purpose, the utility model adopts following technical scheme: a kind of numeric display unit, comprise casing, display screen component and the heater element that is electrically connected with described display screen component, described display screen component and described heater element all are contained in described casing, and described heater element separates installation with described display screen component.
As further improvement of the utility model, be provided with heat abstractor in described casing.
As further improvement of the utility model, described heat abstractor is heat radiator or extraction fan or heat exchanger or compression refrigerating system.
As further improvement of the utility model, the air outlet that is provided with air inlet on described casing and is connected with described air inlet.
As further improvement of the utility model, described casing comprise antetheca that described display screen component is installed, with the rear wall of described antetheca parallel interval setting and the pair of sidewalls that is connected described antetheca and described rear wall.
As further improvement of the utility model, described air inlet and described air outlet all are arranged on described rear wall.
As further improvement of the utility model, described air inlet is positioned at the below of described air outlet.
As further improvement of the utility model, have at least a place to be provided with the blower fan apparatus that promotes airflow circulating in described air inlet, described air outlet.
As further improvement of the utility model, described air inlet and described air outlet place are provided with waterproof construction.
As further improvement of the utility model, described numeric display unit also comprises on the antetheca that is arranged on described casing and in order to protect the transparent screen of described display screen component.
The beneficial effects of the utility model are: compared to prior art, separate installation with display screen component due to heater element, thereby reduced the heat of described heater element generation to the impact of described display screen component, improved the radiating effect of described display screen component.

Embodiment
See also Fig. 1 and in conjunction with Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the heater element 14 that the utility model numeric display unit 100 comprises casing 10, be contained in display screen component 20 in described casing 10, be contained in described casing 10 and be electrically connected with described display screen component 20, be arranged on the transparent screen 30 on described casing 10.Described heater element 14 separates installation with described display screen component 20.Described heater element 14 can be the element that can produce heat that uses in the numeric display units 100 such as power module 140, image display 141.Described image display 141 can specifically be divided into the assemblies such as image-driven module and backlight module.Described casing 10 is rectangular-shaped, can be designed to as required other shapes in actual applications.
See also Fig. 1 and in conjunction with Fig. 2, Fig. 3 and shown in Figure 4, described casing 10 comprise antetheca 11 that described display screen component 20 is installed, with the rear wall 12 of described antetheca 11 parallel interval settings and the pair of sidewalls 13 that is connected described antetheca 11 and described rear wall 12.Described transparent screen 30 is arranged on the position of the corresponding described display screen component 20 of described antetheca 11, in order to protect described display screen component 20, and the setting that is spaced a distance of described transparent screen 30 and described display screen component 20.Described numeric display unit 100 also comprises the heat abstractor 50 that is arranged in described casing 10.In the present embodiment, described heat abstractor 50 is heat radiator, and described heat radiator is consistent with direction of ventilation so that dissipation of heat.The air outlet 122 that is provided with air inlet 121 on described casing 10 and communicates with described air inlet 121, flow out so that air enters in described casing 10 and from described air outlet 122 from described air inlet 121, thereby the heat that is produced by described heater element 14 in described casing 10 is taken out of.In the present embodiment, described air inlet 121 and described air outlet 122 all are arranged on described rear wall 12, but in other embodiments, described air inlet 121, described air outlet 122 can also be arranged on antetheca 11, sidewall 13.Described air inlet 121 is arranged on the below of described air outlet 122, thereby make air enter in described casing 10 from the below through described air inlet 121, described air upwards flow to described air outlet 122 places from the interior outflow of described casing 10, and then take the heat of described display screen component 20 generations and the heat of described heater element 14 generations out of described casing 10, play the effect to described display screen component 20 coolings.Have at least a place to be provided with the blower fan apparatus 40 that promotes airflow circulating in the air inlet 121 of described casing 10, air outlet 122.The air inlet 121 of described casing 10 is provided with waterproof construction with air outlet 122 places, so that anti-sealing enters the inside of described numeric display unit 100.In the present embodiment, the back side of described display screen component 20 is equipped with heat abstractor 50, and heat abstractor 50 is specially heat radiator, but described heat abstractor 50 can be extraction fan, heat exchanger, compression refrigerating system or other refrigerating plants in other embodiments, can strengthen the radiating effect of described display screen component 20.In addition, the blower fan apparatus of described air inlet 121 or the 122 places setting of described air outlet also can play the effect of strengthening heat radiation.
