A Fiber Laser Two-way Bending Tube Heat Exchange Chiller

Abstract

The invention provides a fiber-optical laser double-path elbow heat-exchange cooling water machine. The fiber-optical laser double-path elbow heat-exchange cooling water machine comprises a water tank. A cooling system formed by sequential connection of an evaporator, a throttle, a condenser and a compressor is arranged on the water tank. A temperature sensor is arranged in the water tank. A watersupply pipe is connected to the water tank, and is sequentially provided with a water suction pump and a valve switch along the water supply direction. A filter screen is arranged in the water supplypipe. A generator cooling pipe is connected to the tail end, away from the water tank, of the water supply pipe, and is connected with a first return pipe, used for returning water to the water tank,after cooling water flows through a laser generator. A cutting head cooling pipe leading to a cutting head is connected to the tail end, away from the water tank, of the water supply pipe, and is connected with a second return pipe, used for returning the water to the water tank, after the cooling water flows through the cutting head. The first return pipe twines below the cutting head cooling pipe in a multi-bend elbow structure at a position close to the cutting head cooling pipe. A water drain pipe is arranged at the bottom of the water tank. The fiber-optical laser double-path elbow heat-exchange cooling water machine has the advantages that circulating water can be fully utilized for heat exchange and cooling, and accordingly, energy conservation and environment protection are realized.

Description

technical field [0001] The invention relates to the technical field of laser cutting cooling, in particular to a fiber laser double-path bent pipe 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 has found in practice: the temperature of the cooli...

[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, and the hot air flow tends to move upwards, but this energy is ignored in the prior art Therefore, an improvement scheme is proposed on the basis of the chiller in the prior art
