[0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits can be bent, wound, and folded freely, and can withstand millions of dynamic bends without damaging the wires. The spatial layout requires arbitrary arrangement, and arbitrary movement and expansion in three-dimensional space, so as to achieve the integration of component assembly and wire connection, greatly reduce the volume and weight of electronic products, and be suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. However, during the use of flexible circuit boards, the previous flexible circuit boards had serious heat generation during use, and the heat could not be dissipated in the sealed equipment, resulting in too high working environment temperature of the circuit board, resulting in It is prone to problems, and also affects the working life of the working flexible circuit board. Therefore, it is necessary for the present invention to propose a square-wave circulating liquid cooling device for the strip-shaped flexible circuit board. The cooling liquid for cooling the flexible circuit board is always kept at a low temperature, and the cooling effect is better, and the present invention can adapt to flexible circuit boards of different lengths without affecting the cooling of the flexible circuit board by the cooling member
