A notebook computer suitable for low temperature environment

Abstract

The invention provides a notebook computer suitable for low-temperature environment, wherein a battery compartment is arranged on the back of the notebook computer; The battery compartment comprises atemperature-controlled electric heating component; The temperature-controlled electric heating module comprises a heating circuit triggered by a temperature sensor, an electric heating film and a temperature control unit. The electric heating film is fixedly bonded to the bottom of the battery compartment through a high-temperature resistant adhesive; The temperature control unit comprises a temperature control chip and a relay. The invention fixedly arranges ultra-thin graphene heating film in the battery compartment of the notebook computer, and intelligently controls the heating circuit based on the temperature sensor to reasonably control the internal temperature of the battery compartment, so as to ensure that the notebook computer runs normally under the low temperature environment.The graphene heating film provided by the invention is mature in technology, safe, does not occupy the space of the battery compartment with ultra-thin structure, has obvious temperature raising effect, low cost, is simple in implementation, and is suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the technical field of computers, in particular to a notebook computer suitable for low-temperature environments. Background technique [0002] The use of rechargeable batteries is one of the advantages of notebook computers over desktop computers, which can greatly facilitate the use of notebook computers in various environments. The most commonly used laptop battery today is the lithium-ion battery. [0003] The temperature is the most important parameter affecting the performance of the battery. In all testing systems of the battery, the temperature must be indicated. The reason is that the temperature has a greater impact on the performance of the battery, including the internal resistance of the battery, charging performance, discharging performance, safety, Lifespan etc. [0004] The influence of temperature on discharge performance directly reflects on discharge capacity and discharge voltage. As the temperature decre...

Problems solved by technology

[0005] At present, there are many low-temperature operations in the society, such as work in high mountains and plateaus, scientific research work in the North and South Poles, low-temperature workshops in modern factories, and field testing operations in cold climates. Many jobs require the support of laptop computers. Such problems are generally connected to an external power supply or by adding an auxiliary low-temperature-resistant battery inside the notebook, but the external power supply is only suitable for indoor use, and most low-temperature operations are outdoor operations; adding low-temperature-resistant auxiliary batteries increases battery costs on the one hand, and on the other On the one hand, because the notebook itself is a highly integrated product, the internal space utilization rate is already extremely high, and adding an auxiliary battery will inevitably sacrifice part of the space, thereby affecting the design of the entire notebook computer space structure
