Circulating liquid cooling method for flexible circuit board

Abstract

The invention relates to a circulating liquid cooling method, which comprises the following steps that: S1, cooling liquid in a liquid storage tank flows into a cooling pipe b and a cooling pipe a by a plunger pump a in a suction state, and the cooling liquid which is previously positioned in the cooling pipe b and the cooling pipe a and has increased temperature flows into a pump shell of the plunger pump a; S2, the plunger pump a in the discharging state discharges cooling liquid in a pump shell of the plunger pump a into a cooling tower for cooling, and a plunger pump b in the suction state sucks the cooled cooling liquid in the cooling tower into a pump shell of the plunger pump b; S3, the plunger pump a in the suction state enables the cooling liquid in the liquid storage tank to flow into the cooling pipe b and the cooling pipe a, the cooling liquid which is located in the cooling pipe b and the cooling pipe a previously and has the temperature increased flows into a pump shell of the plunger pump a, and the plunger pump b in the discharging state discharges the cooling liquid in the pump shell of the plunger pump b into the liquid storage tank; and S4, the steps S2-S3 are repeated.

Description

Problems solved by technology

[0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates, which can meet the design needs of smaller and higher-density installations, and also help reduce assembly processes and enhance reliability. Flexible circuit boards Widely used in electronic products, but during the use of flexible circuit boards, the previous flexible circuit boards have serious heat generation during use, and it is easy to cause heat to not dissipate in sealed equipment, resulting in excessive temperature of the circuit board working environment , leading to circuit boards prone to problems and also affecting the working life of flexible circuit boards. Therefore, it is necessary for the present invention to propose a circulating liquid cooling method for flexible circuit boards. The cooling liquid for cooling the flexible circuit board is always kept at a low temperature, and the cooling effect is better, and the invention can adapt to flexible circuit boards of different lengths without affecting the cooling of the flexible circuit board by the cooling member
