Water device, is greatly saved system water and operating cost.
Described coolant stores container and heat exchanger may be contained within below ground, does not affect floor space and intelligent transportation
Display screen attractive in appearance, and underground temperature is relatively low, and coolant can be from the impact of external high temperature.
The entrance of described heat exchanger and coolant store the outlet of container and are provided with filter screen, and impurity can be hindered to enter heat exchange
In device and flexible pipe, it is to avoid heat exchanger blocks, it is ensured that coolant circulation is smooth and easy.
Also include that the hollow column for supporting display screen, the side opening that described hollow column contacts with casing are provided with side
Hole, the bottom of described casing offers bottom outlet.Hollow column is used for placing flexible pipe, and plays the effect of protection flexible pipe.Flexible pipe leads to
Cross bottom outlet and side opening enters hollow column, and enter below ground through hollow column.
Described flexible pipe is pasted onto heat sink edge by thermal paste.Thermal paste is a kind of low thermal resistance, the leading of high thermal conductivity
Hot material, can make flexible pipe be fully contacted with heat sink, improves heat conduction efficiency, is particularly well-suited to display screen inherent space constraints
Conduction of heat demand.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
1. by installing flexible pipe at heat sink edge, and in flexible pipe, it is passed through coolant, heat sink quickly can be dissipated
Heat, substantially increases the radiating efficiency of intelligent transportation display screen；
2., by arranging temperature sensor and central controller in the inside of intelligent transportation display screen, can realize automatically controlling
System；
3. by arranging heat exchanger in flexible pipe exit, and make heat exchanger be connected with coolant storage container, can realize cold
But the recycling of liquid, saves the energy；
4. present configuration is simple, does not affects the appearance, has practicality.
