技术领域technical field

本发明涉及电脑桌领域，尤其涉及一种智能自动散热电脑桌。The invention relates to the field of computer desks, in particular to an intelligent automatic heat dissipation computer desk.

背景技术Background technique

笔记本电脑因其便携性，已经被人们所喜爱。在使用笔记本电脑办公或者娱乐时，笔记本电脑通常会放置在一个桌面较为平坦的电脑桌上。但是，现有的电脑桌功能较为单一，并且不具有自动散热功能。如果笔记本电脑长时间在电脑桌上运行，会因其工作散出很多热量。这样热量如果不能够及时做散热处理，很容易导致笔记本电脑因热量聚集而出现死机、蓝屏等运行异常情况。Laptops have been loved by people for their portability. When using a laptop for work or entertainment, the laptop is usually placed on a computer desk with a relatively flat desktop. However, the existing computer desks have relatively simple functions and do not have the function of automatic heat dissipation. If the laptop is running on the computer desk for a long time, it will dissipate a lot of heat due to its work. In this way, if the heat cannot be dissipated in time, it is easy to cause the notebook computer to crash, blue screen and other abnormal operations due to heat accumulation.
