Embodiment Construction

[0046] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0047] Such as figure 1 Shown is a schematic structural diagram of a printed circuit board according to an embodiment of the present invention. The printed circuit board includes: a circuit board body 101 and a heating component 102 arranged on the circuit board body 101. The heating component 102 generates Heat, so that the temperature of the heating component 102 or other components around it rises, in order to take away the heat generated by the heating component 102, the printed circuit board also includes: an ion cooling component 103 and an ion cooling component 103 for the ion The power supply assembly 104 powered by the cooling assembly 103, the ion cooling assembly 103 and the power supply assembly 104 are both arranged on the circuit board body 101, the power supply assembly 104 has a positive p...

Abstract

The invention provides a printed circuit board, a computer and a radiating method. The printed circuit board comprises a circuit board body, a heating component, a power supply component and an ion radiating component, wherein the heating component is arranged on the circuit board body; the power supply component is arranged on the circuit board body and provided with a positive electrode and a negative electrode; the ion radiating component is arranged on the circuit board body and positioned in a preset range at the periphery of the heating component, and comprises an emitting electrode and a receiving electrode; the emitting electrode is connected with the positive electrode of the power supply component, the receiving electrode is connected with the negative electrode of the power supply component, and when the power supply component supplies power to the ion radiating component, the emitting electrode discharges so as to ionize the air to generate electric ions which drive air to move to the receiving electrode. According to the invention, the temperature of a shell of the computer can be reduced effectively.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a printed circuit board, a computer and a heat dissipation method. Background technique [0002] In existing notebook computers, the cooling fan is usually installed near the CPU (Central Processing Unit, central processing unit). In the case of insufficient air pressure of the cooling fan, heat-generating components far away from the CPU, such as network cards, cannot be effectively dissipated. , which in turn affects the temperature rise of the surrounding computer case. [0003] In the prior art, it is possible to reduce the air inlets near the CPU by increasing the speed of the cooling fan, or opening air inlets around the heating components far away from the CPU, so as to force cold air to enter from the remote air inlets, thereby reducing the size of the computer case. body temperature. However, a high-speed fan will inevitably generate greater system noise. In addition...
