Abstract

Subject of the invention is the construction of an external display including a light display for information or commercial messages, in particular of larger size, providing safe operation by stabilising the temperature of vital display components. According to their type the displays are mainly LCD displays, plasma displays, projectors etc. The invention eliminates the deficiency of the current state of the art technical development by using a double or single insulated enclosure, which makes it possible to use of displays outdoors under any weather conditions and by using the Peltier modules or external source of cold air, cooled in the earth, and an electric heater, which can both cool and heat the atmosphere within the outdoor display thus requiring considerably less space than an evaporator and compressor, as well as consuming less electric power.

Description

The object of the invention is the construction of an external display with a light display of information or advertising messages, especially of larger dimensions, which enables reliable operation by stabilizing the temperature of the vital elements of the display. The displays are mainly LCD screens, plasma screens, projectors, etc.

The invention relates to an external display (i) with a dual housing and a built-in computer and a Peltier module, (ii) a dual housing, a built-in computer and an external cooled air source, (iii) a dual housing, a built-in Peltier module and an external computer, (iv ) with dual enclosure and external computer and external cooled air source, (v) with enclosure and integrated computer and Peltier module, (vi) with enclosure, integrated computer and external cooled air source, (vii) with enclosure, integrated Peltier module and external a computer and (viii) a chassis and an external computer and an external chilled air source.

Well-known LCD displays, plasma screens, projectors, etc. they generate heat and can be overheated or overcooled in very cold environments. Both cause unreliable operation or malfunction.

Known refrigerated displays heated using Peltier technology are unusable outdoors due to resistance to different weather conditions. In the case of a standard heating system or. however, the evaporator and compressor cooling is a limitation of the excessive consumption of space and electricity, as well as the need to dry the air in the housing due to the debris / condensation of the glass and the surface of the built-in display e.g. LCDs, plasma screens, projectors, etc.

The invention eliminates the disadvantages of the prior art by using a double or single insulated housing, which allows the use of outdoor displays in all weather conditions and, preferably, using Peltier modules (or an external cooled air source and electric heater), which cool and heat the atmosphere in an external display and take up significantly less space than the evaporator and

-2compressor, and also consume less electricity. The condensation problem is solved so that the outside air does not enter the atmosphere where the screen, projector, etc. are installed: in versions (i), (ii), (iii) and (iv) the latter is enclosed in an inner housing, in embodiments (v), (vi), (vii) and (viii) no outside air enters the housing. An external display according to the invention allows the use of large-scale outdoor display devices, regardless of weather conditions.

The invention can be used in several versions:

- External display with dual housing, where air is not interchanged with the ambient air in the inner housing, computer and power supply unit integrated in the internal housing and Peltier module integrated on the inner housing;

- External display with dual housing, where air is not interchanged with the ambient air in the inner housing, and a computer and power supply unit built into the internal housing. The cooled natural air (cooled in the earth) is fed through the pipe into the inner housing. The housing is heated by an electric heater;

- External display with dual housing, where air is not interchanged with the ambient air in the inner housing, and a Peltier module mounted on the inner housing and a power-steering unit installed in the inner housing. The computer is located outside the chassis;

- External display with dual housing, where air is not interchanged with the ambient air in the inner housing, and a power supply and control unit integrated in the inner housing. The computer is located outside the chassis. The cooled natural air (cooled in the earth) is fed through the pipe into the inner housing. The housing is heated by an electric heater;

- External display with a single housing, where air is not exchanged with the ambient air in the housing, a computer and a power supply control unit installed in the housing, and a Peltier module (insulated against moisture) built into the housing;

- External display with a single housing, where air is not exchanged with ambient air in the housing, and a computer and power supply control unit are installed in the housing. The cooled natural air (cooled in the earth) is fed through the pipe into the inner housing. The housing is heated by an electric heater;

- External display with a single housing, where air is not exchanged with the ambient air in the housing, and a Peltier module (insulated against moisture) and a power supply and control unit integrated in the housing. The computer is located outside the chassis;

-3- External display with a single housing, where air is not interchanged with the surrounding air, and a power supply and control unit is installed in the housing. The computer is located outside the chassis. The cooled natural air (cooled in the earth) is fed through the pipe into the inner housing. The housing is heated by an electric heater.

In the following, the invention is shown on the basis of the basic embodiment and the seven variants in the accompanying drawings, in which an external display is shown, from the back:

Figure 1 - Basic design of an external display

Figures 2 to 8 - seven versions of the external display from Figures 1

The numerical codes of the individual components of the external display in the accompanying drawings in all eight figures represent the same component of the external display.

The basic part of the external display is formed by the base housing 1, which has a glass 19 at the front, behind which the display device 18. The camera 15 is located at the top of the base housing, the speakers 20 and the burglar alarm device 10 are mounted on the bottom and fastening 5.

In the first embodiment of the external display, the base housing 1 houses an inner housing 2 in which are inserted: display device 18, computer 11, power supply control unit 12, fans of the inner housing 16, moisture absorbers 8, and an atmospheric temperature gauge in the inner housing 17 Only one or more Peltier modules 9 are attached to the inner casing 2 only, which, if necessary, either cools or heats the atmosphere in the inner casing 2. On the outer casing 1 there are also fans 3 and 4 for exchange of air with the surroundings, fans 7 for circulation air around the inner casing 2, air barrier 6 for proper air circulation, temperature gauges 14, and exterior connections for electricity and the Internet 13.
