A pre-refrigeration system

Abstract

The invention relates to a pre-refrigeration system comprising a control module, a computer motherboard and electronic elements and components on the computer motherboard, and a heat dissipation device which is arranged on a computer case; the control module comprises a sensing module and an actuation module which is connected with the sensing module; the sensing module can detect the changes of the use rate of the electronic elements and devices when working, and monitor the changes of the working current of the motherboard; and the actuation module can process a signal which is transmitted by the sensing module, and can control the operation of the heat dissipation device. According to the pre-refrigeration system, the heat dissipation device can be started in advance according to the use conditions of a computer for heat dissipation in advance, the refrigeration output of the heat dissipation device can be adjusted, so that the refrigeration is quick and effect, electricity is saved, and the heat dissipation efficiency is improved.

Description

technical field [0001] The invention relates to a cooling system for controlling electronic components, in particular to a pre-cooling system. Background technique [0002] When the computer is operating under a high load, generally, high-power components will naturally bring a lot of heat, which affects the computing power of the computer itself, so an external cooling device is required. At present, the heat dissipation devices used in computer systems are mainly cooling fans. Whether it is a desktop computer or a notebook computer, it will be equipped with a cooling fan fixed with the CPU. The cooling fan will start working when the computer is started, regardless of whether the computer needs additional For heat dissipation, the heat dissipation fan will rotate at a constant speed to dissipate heat from the computer CPU, which will waste a lot of electric energy and also generate certain noise, which will affect the surrounding environment. [0003] Although, some exist...

Problems solved by technology

However, not only the CPU but also various plug-ins and components inside the computer will also emit heat, such as hard disks, memory sticks, and graphics cards. As a result, it is not suitable for the cooling of the entire system.

Moreover, this heat dissipation method responds slowly, and it is easy to cause the temperature of the computer to exceed the upper limit that the hardware can withstand, reducing its service life, or even burning out the computer.

And the heat dissipation method of existing computer is generally delay passive mode, when temperature sensor detects that the temperature of CPU rises to certain limit, heat dissipation system just begins to work, and at this moment, the electronic components and parts local temperature on the computer motherboard has already The rise is too high, and the cooling system cannot play an effective protective role
