Accompanying drawing explanation
Fig. 1 is according to the principle schematic of a kind of high power laser double temperature double control cooling-water machine of the utility model preferred embodiment.
Embodiment
By the following examples, by reference to the accompanying drawings the utility model is described in further detail.
Referring to Fig. 1, a kind of high power laser double temperature double control cooling-water machine, comprises refrigerating system, the water at low temperature circulatory system, the normal-temperature water circulatory system and temperature control system.Refrigerating system comprises compressor 1, bypass solenoid valve 21, fan electromotor 3, fin condenser 2, device for drying and filtering 4, refrigeration electromagnetically operated valve 5, heating power expansion valve 6 and evaporator 19, and evaporator 19 is Stainless Steel Coil.The water at low temperature circulatory system comprises low temperature water tank 18, low temperature water pump 8, discharge switch 17, water at low temperature temperature sensor 7 and heat-generating pipe 12.The normal-temperature water circulatory system comprises normal temperature water tank 16, heat exchanger 11, normal temperature water pump 10, discharge switch 15, normal-temperature water temperature sensor 13 and heat-generating pipe 14, and heat exchanger 11 is Stainless Steel Coil.Low temperature water tank 18 connects by an interior circulating water pump 9 with normal temperature water tank 16.The laser head of the delivery port connecting laser of low temperature water pump 8 in addition, backwater end is connected with low temperature water tank 18, and backwater end is also connected with discharge switch 17.Normal temperature water pump 10 imports of the normal-temperature water circulatory system are connected with normal temperature water tank 16, and exit of pump is connected with the Laser Power Devices of laser, and backwater end is connected with normal temperature water tank 16, and backwater end is also connected with discharge switch 15.
The operational mode of this enforcement: set respectively water at low temperature with the needed temperature of normal-temperature water and the temperature difference on thermostat, start, low temperature water pump 8, normal temperature water pump 10, interior circulating water pump 9, compressor 1 start work sequentially, when water at low temperature temperature sensor 7 detects water at low temperature temperature >=set temperature+temperature difference, 5 adhesives of refrigeration electromagnetically operated valve, bypass solenoid valve 21 disconnects, and refrigerating system starts water at low temperature to carry out refrigeration cool-down; When water at low temperature temperature≤set temperature being detected, bypass solenoid valve 21 adhesives, refrigeration electromagnetically operated valve 5 disconnects, low temperature water pump 8, compressor 1 work on, the high temperature and high pressure gas ejecting from compressor, by bypass solenoid valve 21 evaporator 19 of flowing through, is realized water at low temperature is carried out to the object that hot-gas bypass makes water at low temperature temperature constant temperature.Simultaneously, interior circulating water pump 9 is with the 9 operation work of normal temperature water pump, interior circulating water pump 9 is continuously extracted into heat exchanger 11 water at low temperature, return low temperature water tank 18, utilize water at low temperature to follow the temperature difference of normal-temperature water, realize the cooling to normal-temperature water, when normal-temperature water temperature sensor 13 detects the temperature≤set temperature of normal-temperature water, interior circulating water pump 9 stops periodic duty, and when normal-temperature water temperature sensor 13 detects the temperature >=set temperature+temperature difference of normal-temperature water, interior circulating water pump 9 starts again periodic duty.So circulation, meets the laser head of laser with the requirement of Laser Power Devices to different quality, different temperatures.
In cold snap, when ambient temperature is during lower than 0 ℃, cooling-water machine water tank will likely freeze, and while starting shooting first, if not ice-out, ice cube will be along with water pump pump be to laser, and not only blocking pipeline, will damage laser when serious.And now can not be all ice-out with hot-gas bypass, moreover it be also slow to melt efficiency.For this problem, low temperature water tank 18 at cooling-water machine is respectively equipped with two heat-generating pipes 12 with normal temperature water tank 16 bottoms, 14, when water at low temperature temperature sensor 7, when normal-temperature water temperature sensor 13 detects temperature <5 ℃, heat-generating pipe 12, 14 start working, now compressor 1, low temperature water pump 8, normal temperature water pump 10, interior recirculated water 9 is idle, when water at low temperature temperature sensor 7, when normal-temperature water temperature sensor 13 detects water temperature >5 ℃, heat-generating pipe 12, 14 quit work, low temperature water pump 8, normal temperature water pump 10, interior recirculated water 9, compressor 1 startup work.
Flow switch 17,15 mainly plays the effect of monitoring discharge in water circulation system; when monitoring the laser head of client laser device or the circling water flow rate of Laser Power Devices lower than the alarm setting value of flow switch 17,15; flow switch provides a switch alarm signal; thereby cut off client laser device power supply; make laser can not cause excess Temperature and burn laser because of flow is too small, play the effect of protection laser.
Actual motion is given an example: suppose 28 ℃ of the initial water temperatures of water at low temperature, the needed water temperature of client laser device laser head is 22 ℃ of design temperatures, and the temperature difference is set as 0.1 ℃.The initial water temperature of normal-temperature water is 30 ℃, the needed water temperature of Laser Power Devices is 27 ℃ of design temperatures, the temperature difference is set as 2 ℃, start, low temperature water pump 8, normal temperature water pump 10, interior circulating water pump 9, compressor 1 starts operation, 28 ℃ of the temperature that water at low temperature temperature sensor 7 detects water at low temperature are greater than and set 22 ℃ of temperature, refrigerating system operation, and cooling-water machine starts refrigeration, now bypass solenoid valve 21 disconnects, and 5 adhesives of refrigeration electromagnetically operated valve.When water temperature being detected and be less than 22 ℃, bypass solenoid valve 21 adhesives, refrigeration electromagnetically operated valve 5 disconnects, and refrigerating system starts hot-gas bypass and heats; Simultaneously, 30 ℃ of the temperature that normal-temperature water temperature sensor 13 detects normal-temperature water are greater than while setting 27 ℃ of temperature, internal circulation pump 10 is started working, by the heat exchanger 11 water at low temperature being extracted in normal temperature water tank 16, with normal-temperature water, carry out heat exchange, make normal-temperature water cooling down, when normal-temperature water temperature being detected and be 27 ℃, interior circulating water pump 9 quits work, when normal-temperature water temperature >29 ℃ being detected, interior circulating water pump 9 starts again to start to work.So repeat, reach the object of temperature control constant temperature.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, make concrete change or change and all belong to protection range of the present utility model.
