Abstract

The invention discloses a dual temperature control cooling system, a control method thereof, and a dual temperature control cooling machine. Wherein, the dual temperature control cooling system includes: a heat exchanger, arranged on the high-temperature cooling water supply branch road led by the low-temperature cooling water supply circuit of the evaporator, for heating the low-temperature cooling water flowing out of the evaporator; The heat exchanger and the condenser share a condensing fan, and the condenser is located between the condensing fan and the heat exchanger, and the outlet air of the condensing fan passes through the condenser and the heat exchanger in sequence. On the premise of realizing the dual temperature control function, the present invention simplifies the waterway, and the high-temperature cooling waterway does not use the mixing of low-temperature water and high-temperature return water or forced convection heat exchange, but realizes the heating of the high-temperature cooling waterway through condensation heat to achieve temperature rise At the same time, the condensation heat is to use the hot air blown out from the condenser to realize the utilization of waste heat and save energy. There is no need to add additional electric heating to control the temperature, reducing costs.

Description

technical field [0001] The invention relates to the technical field of cooling units, in particular to a dual-temperature control cooling system, a control method thereof, and a dual-temperature control cooling machine. Background technique [0002] When the laser machine tool is working, the main body and the lens of the laser machine tool need to continuously circulate cold water to take away the heat generated by the machine tool, but the temperature of the cold water required by the two is different. The cooling water temperature is about 28-30°C. Ordinary machine tool coolers can only output cooling water at one temperature, which is suitable for the temperature of the main body of the laser machine tool. However, low-temperature cold water will cause condensation on the lens of the laser machine tool, which will affect the service life and even cause damage. [0003] The dual-temperature control cooling machine is a special cooling equipment with high efficiency, energ...
