Optical fiber laser water cooler

Abstract

The invention discloses an optical fiber laser water cooler. The optical fiber laser water cooler comprises a water tank; the water tank is provided with a refrigeration system which is formed by an evaporator, a throttling valve, a condenser and a compressor which are sequentially connected; a temperature is arranged inside the water tank; the water tank is connected with a water supply pipe forsupplying cooling water; the water supply pipe is sequentially provided with a water pump and a valve switch in the water supply direction; a filter is arranged inside the water supply pipe; the watersupply pipe is connected to a laser generator; the water supply pipe is connected with a warm water pipe connected to a cutting head after the cooling water flows through the laser generator; the warm water pipe is connected with a refluxing pipe which refluxes to the water tank after warm water flow flows through the cutting head; and the bottom of the water tank is further provided with a waterdischarging pipe. The optical fiber laser water cooler disclosed by the invention can realize cooling by utilizing circulating water more fully, saves energy and protects the environment.

Description

technical field [0001] The invention relates to the technical field of laser cutting cooling, in particular to an optical fiber laser 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 passing through ...

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
