A fiber laser dual-path heat exchange chiller with temperature control function

Abstract

The invention discloses a fiber laser double-path heat exchanger cooling-water machine with a temperature control function. The fiber laser double-path heat exchanger cooling-water machine with the temperature control function comprises a water tank with a refrigerating system; a temperature sensor is arranged inside the water tank and connected with a control panel; the water tank is connected with a water feed pipe; the water feed pipe is provided with a water pump and a valve switch; the water feed pipe is connected with a generator cooling pipe; the generator cooling pipe is connected witha transition pipe; the water feed pipe is connected with a cutting head cooling pipe; the cutting head cooling pipe is connected with a second return pipe; the transition pipe is connected with a temperature control tank internally provided with a temperature control switch; the temperature control switch is connected with the control panel; the temperature control tank is connected with a firstwater pipe and a second water pipe; the first water pipe is internally provided with a first valve, the second water pipe is internally provided with a second valve, and the first valve and the secondvalve are connected with the control panel; the part, close to the cutting head cooling pipe, of the first water pipe is of a spiral structure and wound outside the cutting head cooling pipe; the spiral structure is connected with a first return pipe; the second water pipe is connected with a constant temperature tank; and the constant temperature tank is connected with a branch communicating tothe first water pipe. The fiber laser double-path heat exchanger cooling-water machine with the temperature control function can fully use circulating water for heat exchange cooling and is accurate in temperature control.

Description

technical field [0001] The invention relates to the technical field of laser cutting cooling, in particular to an optical fiber laser dual-path heat exchange chiller with a temperature control function. Background technique [0002] The laser chiller is a cooling device suitable for various laser cutting machines. In addition to cooling the laser generator with low temperature (such as 20°C) cooling water, a laser cutting machine also needs warm water with a water temperature slightly higher than the ambient temperature (such as 30°C) to cool the laser cutting head and other peripheral optical equipment. [0003] Most of the existing technologies adopt two ways of independent circulating cooling of two water tanks or two ways of cooling in a single water tank, such as two patents with application numbers: CN201620908072.0 and CN201620907878.8, both of which require at least one set of refrigeration equipment And a set of heating equipment, and our company has found in pract...

[0003] Most of the existing technologies adopt two ways of independent circulating cooling of two water tanks or two ways of cooling in a single water tank, such as two patents with application numbers: CN201620908072.0 and CN201620907878.8, both of which require at least one set of refrigeration equipment And a set of heating equipment, and our company has found in practice: the temperature of the cooling water after passing through the laser generator can meet the cooling of the cutting head, even if there is heat loss in the pipeline or extreme temperature, it can also be slightly corrected The cooling water is completely supplied by the water tank for reheating, but the utilization of this energy is ignored in the prior art, so an improvement scheme is proposed on the basis of the chiller in the prior art
