A fiber laser dual-path heat exchange chiller

Abstract

The invention discloses an optical fiber laser two-path heat exchange water cooler. The optical fiber laser two-path heat exchange water cooler comprises a water tank, wherein the water tank is equipped with a refrigerating system which is formed by sequentially connecting an evaporator, a throttle valve, a condenser and a compressor, a temperature sensor is arranged in the water tank; the water tank is connected with a water cooling tube; the water cooling tube is sequentially equipped with a water suction pump and a valve switch in a water supply direction; a filter screen is arranged in thewater cooling tube; the tail end, away from the water tank, of the water cooling tube is connected with a generator cooling tube; after cooling water flows through a laser generator, the generator cooling tube is connected with a first reflow tube which reflows into the water tank; the tail end, away from the water tank, of the water cooling tube is further connected with a cutting head cooling tube which extends to a cutting head; after cooling water flows through the cutting head, the cutting head cooling tube is connected with a second reflow tube which reflows into the water tank; the position, close to the cutting head cooling tube, of the first reflow tube is of a spiral structure and is wound outside the cutting head cooling tube; and the bottom of the water tank is further equipped with a lower water tube. The optical fiber laser two-path heat exchange water cooler utilizes circulating water to perform heat exchange and cooling more sufficiently, and is energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of laser cutting cooling, in particular to a fiber laser dual-path heat exchange chiller. 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 found in practice: the temperature of the cooling water after p...

Problems solved by technology

[0003] Most of the existing technologies adopt two ways of independent circulating cooling of double water tanks or single water tank and two-way cooling. For example, 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 found in practice: the temperature of the cooling water after passing through the laser generator can meet the cooling of the cutting head, but the utilization of this energy is ignored in the prior art, so in the prior art An improvement plan is proposed based on the chiller
