Method for removing obstruction in micro-channel cooling equipment and self-repairing micro-channel cooling equipment

Abstract

The invention discloses a method for removing an obstruction in micro-channel cooling equipment and self-repairing the micro-channel cooling equipment. The method is applicable to a cooling system for the micro-channel cooling equipment. The cooling system comprises a refrigerating device, a coolant storage tank, a booster pump, a filter, the micro-channel cooling equipment, a two-position four-way reversing electromagnetic valve and a control device, wherein a water supply pipeline and a water return pipeline are arranged on the micro-channel cooling equipment; four channels of the two-position four-way reversing electromagnetic valve are respectively communicated with the water supply pipeline, the water return pipeline and an inlet and an outlet of the micro-channel cooling equipment; a pressure sensor is arranged on the water supply pipeline; a flow sensor is arranged on the water return pipeline; and by switching different working stations of the two-position four-way reversing electromagnetic valve, the inlet and the outlet of the micro-channel cooling equipment can be exchanged. The invention has the advantages that: the method is simple and easy to operate; the control device receives pressure and flow signals and drives reversing of the two-position four-way reversing electromagnetic valve; pollution removal and self-repairing of the micro-channel cooling equipment are effectively realized; and the cooling system can safely operate for a long time and has a good circulation cooling effect.

Description

technical field [0001] The invention relates to a semiconductor laser cooling system, in particular to a method for removing blockages in a microchannel cooling device and self-repairing. Background technique [0002] Semiconductor lasers have been widely used in laser medical treatment, laser cosmetology, and as pump sources for solid-state lasers. With the advancement of technology, the output power of semiconductor lasers has been greatly improved. When high-power semiconductor lasers are liquid-cooled, micro-channel cooling structures are generally used. When the laser system uses a semiconductor laser with a micro-channel cooling structure, if there are particles with a particle size greater than 10 microns in the coolant in the circulation system, it is very likely to cause partial blockage of the micro-channel. Excessive particles will cause severe blockage of the microchannel, so that the heat in the semiconductor laser cannot be taken away in time. The heat is exc...
