Description

Laptop Smart Cooling Rack

technical field

The utility model relates to a cooling frame for a notebook, in particular to an intelligent cooling frame for a notebook computer which is easy to use and can prolong the service life of the notebook computer.

Background technique

Laptop cooling stand is designed to prevent laptops from overheating. The basic structure is to have a bracket, and a fan (fan blade and fan motor) connected to the power supply is placed in the bracket, and the cooling effect is achieved by starting the fan to rotate. Because the fan speed of the existing notebook computer cooling rack is mostly fixed, that is, it does not change with the change of the ambient temperature. When the notebook computer is placed in a high-temperature environment and needs the fan to rotate at a high speed to cool down quickly, the fan still rotates at a constant speed. Reaching the ideal heat dissipation effect causes the notebook computer to be damaged due to excessive temperature, shortens the service life of the notebook computer, and wastes a lot of electric energy. Although the fans of individual heat sinks are equipped with speed control devices, they all need to be manually adjusted according to the ambient temperature, which is inconvenient to use.

Contents of the invention

The utility model aims to solve the above-mentioned technical problems existing in the prior art, and provides an intelligent cooling frame for a notebook computer which is convenient to use and can prolong the service life of the notebook computer.

The technical solution of the utility model is: a notebook computer intelligent heat dissipation rack, which has a bracket and a fan motor, and is characterized in that: a temperature sensor is provided, the output of the temperature sensor is connected with a single-chip microcomputer, and the output of the single-chip microcomputer controls a multi-speed speed control switch , The multi-speed speed control switch is connected with the fan motor through the speed regulation circuit, and the output of the single chip microcomputer is also connected with the display and the alarm device respectively.

The temperature sensor set in the utility model can detect the surface temperature of the notebook, and transmit the obtained temperature signal to the single-chip microcomputer, and the single-chip microcomputer can control the multi-speed speed control switch according to the detected temperature, and adjust the speed of the fan motor through the corresponding speed adjustment circuit At the same time, the detected temperature signal can be displayed on the display, which is convenient to use; when the operating temperature of the notebook reaches the limit, the single-chip microcomputer outputs an alarm signal to drive the set alarm device to alarm, so as to prompt to shut down the notebook computer and avoid the notebook computer from being overheated. And damage, can extend the life of the notebook computer.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

The specific embodiment of the utility model will be described below in conjunction with the accompanying drawings. The embodiment of the utility model has support and fan motor the same as the prior art, and the difference with the prior art is as shown in Figure 1: a temperature sensor is provided, and the temperature sensor should be arranged at a place in contact with the surface of the notebook computer. The output of the single-chip microcomputer is connected with the single-chip microcomputer, the output of the single-chip microcomputer controls the multi-block speed control switch, the multi-block speed control switch is connected with the fan motor through the speed regulation circuit, and the output of the single-chip microcomputer is also connected with the display and the alarm device respectively. Both the multi-block speed control switch and the speed regulating circuit are prior art. For example, the multi-block speed control switch can be an electric contact of a relay, and the speed regulating circuit can be resistors with different resistances.

working principle:

The temperature sensor detects the surface temperature of the notebook in real time, and sends the temperature signal to the single-chip microcomputer. After the temperature signal is amplified and processed by analog-to-digital conversion, the single-chip microcomputer compares it with the standard signal in the storage module to obtain the corresponding control signal. Gear speed control switch, start the speed adjustment circuit corresponding to the multi-speed speed control switch, adjust the fan speed to meet the needs of heat dissipation under different working temperature conditions, save power and prolong the life of the notebook computer.
