Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
As shown in Figure 1, the simple and easy cooling system of a kind of high voltage, comprises framework 2, and the top of framework 2 is provided with controller 1, liquid reserve tank 5 and heat exchanger 6, and heat exchanger 6 is positioned at the side of liquid reserve tank 5, and the bottom of framework 2 is provided with pump 7; The inlet of pump 7 is connected with the liquid outlet of liquid reserve tank 5, and liquid outlet is connected with the inlet of heat exchanger 6, and the liquid outlet place of pump 7 is provided with flow sensor 8.Cold remove system cloud gray model time, controller control pump carries out frequency conversion; Heat passes through heat exchanger, exchange heat is carried out by two cover coolants inside and outside heat exchanger, when internal heat raises, external flow is increased by controller adjust flux transducer, thus take away more heats, can according to internal heat number, regulate the operate power of pump, thus regulate external flow by flow sensor.
In the present embodiment, be provided with blast pipe 3 in the side of liquid reserve tank 5, blast pipe 3 is provided with pressure-regulating valve, ensures the pressure stability of liquid reserve tank inside.When cooling system runs, along with the rising of temperature, pressure raises, and pressure-regulating valve can be opened voluntarily, ensures liquid reserve tank internal operation constant pressure.
In the present embodiment, the side that liquid reserve tank 5 is provided with blast pipe 3 is also provided with liquid level gauge 4.For ensureing the normal operation of pump, liquid reserve tank liquid level is designed to basic, normal, high three gears, when liquid level gauge display liquid level " in " gear time report to the police, when " low " gear, controller control pump shuts down, thus ensures the normal operation of pump and extend the useful life of pump.
In the present embodiment, be provided with liquid injection port 9 at the top of liquid reserve tank 5, in liquid reserve tank, inject liquid by liquid injection port 9.
In the present embodiment, be provided with conductivity sensor in described liquid reserve tank 5, this conductivity sensor is electrically connected with controller.Controller can detect the conductivity of liquid in liquid reserve tank constantly by conductivity sensor, and when the conductivity of liquid is reported to the police lower than during set point, thus after avoiding long-time use, liquid lost efficacy, conductivity reduction brings unnecessary injury.
In the present embodiment, be provided with pressure sensor and temperature sensor in the outer water inlet side of heat exchanger 6, pressure sensor is electrically connected with controller respectively with temperature sensor.Ensure that heat exchanger normally runs under the pressure-bearing allowed and in temperature range by the pressure sensor of outer water inlet side and temperature sensor.
