Example 5
Referring to fig. 4, the present embodiment is provided based on the technical solution of embodiment 4, and further includes a water cooling device 5, where the water cooling device 5 includes an annular cooling pipe 53, a water pump 52 and a water storage tank 51; the annular cooling pipe 53 is disposed on the back of the tablet computer 311, an input end of the annular cooling pipe 53 is communicated with the water storage tank 51 through the water pump 52, and an output end of the annular cooling pipe 53 is communicated with the water storage tank 51.
In some embodiments of the present invention, since the temperature of the tablet pc 311 gradually increases with the use of the tablet pc in the three-dimensional holographic projection process, the service life of the tablet pc is reduced, and therefore the water cooling device 5 is provided to cool down the tablet pc. The implementation mode mainly utilizes the circulation of water in the annular cooling pipe 53, thereby the purpose of cooling is achieved by taking away heat, the annular cooling pipe 53 is arranged at the back of the tablet computer 311, the water pump 52 pumps cold water in the water storage tank 51, the cold water takes away the temperature on the tablet computer 311, and then the cold water flows back to the water outlet tank, thereby the cooling is completed, and the service life is prolonged.
In some embodiments of the present invention, a heat dissipation fan may be directly disposed on the annular cooling pipe 53, so as to enhance the heat dissipation effect, and the heat dissipation fan may be used for heat dissipation of the high-power tablet computer 311.
Example 6
Referring to fig. 4, the present embodiment proposes based on the technical solution of embodiment 5 that a cold water chamber 513 and a hot water chamber 511 are disposed in the water storage tank 51, the cold water chamber 513 is communicated with an input end of the annular cooling pipe 53, the hot water chamber 511 is communicated with an output end of the annular cooling pipe 53, a heat insulating layer 512 is disposed between the cold water chamber 513 and the hot water chamber 511, and a valve is disposed on the heat insulating layer 512.
In some embodiments of the present invention, after the exhibition promotion display device works for a long time, the temperature of the water storage tank 51 may increase due to the untimely heat dissipation, thereby reducing the heat dissipation efficiency. Therefore, the water storage tank 51 is divided into the cold water chamber 513 and the hot water chamber 511, and the thermal insulation layer 512 is arranged between the cold water chamber 513 and the hot water chamber 511, so that the water is prevented from being directly mixed with the cold water in the water storage tank 51 after absorbing the heat on the annular cooling pipe 53, and the integral temperature of the water is increased. Meanwhile, in order to ensure the recycling of water as much as possible, a valve is arranged on the heat insulation layer 512, and when the temperature in the hot water chamber 511 is reduced to be consistent with that in the cold water chamber 513, the valve is opened to convey water into the cold water chamber 513, so that the purpose of recycling is achieved.
In some embodiments of the present invention, to further save energy, the cold water chamber 513 is disposed below the hot water chamber 511, and after the valve is opened, the water flows into the cold water chamber 513 by using gravitational potential energy of the water, thereby improving environmental protection.
Example 7
The present embodiment proposes based on the technical solution of embodiment 6 that the annular cooling pipe 53 is made of copper.
In some embodiments of the present invention, the annular cooling pipe 53 is an important heat dissipating component for connecting the tablet computer 311 and water, so the material thereof needs to be selected in consideration of excellent thermal conductivity. As each material has different heat-conducting property, the materials are respectively silver, copper, aluminum and steel according to the arrangement of the heat-conducting property from high to low. However, if silver is too costly as a heat sink material, although aluminum is much less expensive than copper, it does not conduct as well as copper (on the order of fifty more points of copper). So the best solution is to use copper metal.
Example 8
The present embodiment proposes that the valve adopts an electrically operated valve based on the technical solution of embodiment 6.
In some embodiments of the present invention, if manual control is used for controlling the valve, maintenance personnel need to observe all weather, so as to save manpower, a temperature sensor is disposed in the hot water chamber 511, and an electric valve is used to control the water flow in the hot water chamber 511, once the temperature in the hot water chamber 511 is reduced to a preset temperature, the hot water chamber 511 is automatically opened, thereby completing automatic control, and improving convenience while saving manpower.
Example 9
The present embodiment proposes that, based on the technical solution of embodiment 1, the projection apparatus 3 further includes a fan disposed on the housing 32.
In some embodiments of the present invention, in addition to the tablet computer 311 generating heat, other electronic components also generate heat, and the heat generated by a single electronic component is far less than the heat generated by the tablet computer 311, so that only a fan needs to be disposed on the housing 32 to exhaust the internal heat, thereby avoiding overheating of other electronic components and prolonging the service life of the electronic components.
In some embodiments of the present invention, the fly ash in the dust has a small particle size and a large surface area, so that the fly ash has a strong adsorption capacity, can adsorb harmful substances in the air on the surface of the fly ash, and is acidic or basic. Therefore, the cpu fan can be blocked by excessive dust, the fan stops rotating, the cpu is burnt due to overheating, contact among the board cards can be affected, and corrosion of the circuit board can also be caused.
