Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described:
A kind of mining H bridge cascaded high-voltage explosion-proof frequency converter water-cooling system device disclosed in the utility model, is made up of outer cold, pump group and cooled object.Outer cold part comprises: plate heat exchanger (1), outer water filter Z10(2); Pump group comprises: water pump one M1(3), water pump two M2(4), deionization tank CA(5), filter core tank Z03(6), self-power temp. controlled three-way V301(7), filter Z01(8), heater H 01(9) and high-order swelling water tank C01(10); Cooled object comprises: water wind radiator (11), transformer (12), rectification side power cell (13) and inverter side power cell (14).
Panel radiator (1) adopts advanced Vacuum Soldering Technology, welds mutually nested for each plate, and the limited heatproof of common plate heat exchanger rubber blanket that made it break away from, withstand voltage constraint, have employed 0.3-0.4mm thin plate simultaneously, improve heat exchange efficiency.Its heat exchange principle is: heat-carrying pure water enters plate heat exchanger (1) hot side under the effect of circulating pump, cooling twice medium enters plate heat exchanger (1) cold side, and both are isolated in corrugated plating both sides, as far as possible close to but do not mix, the transmission of heat is completed, to reach heat exchange object during convection current.
Water pump one M1(3), water pump two M2(4) for recirculated cooling water provides power, two water pump a-worker-a-backups, namely when wherein a water pump breaks down, surveillance will be switched to another water pump, simultaneously another water pump is out of service, cooling water flows out rear section through water pump and flows into deionization tank CA(5), deionization tank CA(5) in resin cooling water can be purified further, reduce cooling electrical conductivity of water, make within its allowed band controlling to run at equipment, because when this water-cooling system is run, discharge is very large, deionization tank CA(5) in resin can constantly wearing and tearing, residue is had to flow out unavoidably, therefore at deionization tank CA(5) delivery port adds filter core tank Z03(6), filter core tank Z03(6) can effectively in filtering water route diameter be greater than the impurity component of 10um, flow out part cooling water through water pump and will flow into self-power temp. controlled three-way V301(7), when cooler-water temperature is less than set point, cooling water will all flow into cooled object along pipeline, constantly increase along with equipment runs the heat brought, when cooler-water temperature is greater than design temperature, self-power temp. controlled three-way V301(7) valve open, make a cooling water part be divided to panel radiator (1) and carry out heat exchange with outside cold water, thus reduction cooling water temperature, when cooler-water temperature is less than desired temperature again, self-power temp. controlled three-way V301(7) close, cooling water is made again all to flow into cooled object, circulation like this, make device temperature can maintain within a suitable temperature range, because cooled object caliber is relatively little, in order to prevent pipeline blockage, in pump group loop, add filter Z01(8), this filter effectively can filter the impurity of more than 10um, thus reduces the risk of device interior pipeline blockage, because underground coal mine temperature is relatively low, and relative humidity is very high, so equipment condensation risk is very high, heater H 01(9) be arrange to solve condensation problem, when there is condensation risk supervisory control system judgment device inside, supervisory control system will start heater H 01(9) heat for whole equipment, thus condensation is volatilized get rid of risk, high-order swelling water tank C01(10) Main Function is when major loop cooling water causes volumetric expansion due to reasons such as temperature risings, unnecessary cooling water can be pressed into high-order swelling water tank C01(10) bladder tank in store, otherwise, when major loop cooling water causes volume to reduce due to reasons such as temperature reductions, bladder tank namely with the cooling water input system that pressure itself will store, thus maintains internal system pressure stability.
This water-cooling system is not only directly dispelled the heat to transformer (12), rectification side power cell (13), inverter side power cell (14), and is dispelled the heat to whole casing by water wind radiator (11), thus better control appliance bulk temperature.
By the enforcement of above scheme, the heat that cooled object produces can be taken away by this cooling system efficiently, and H bridge cascaded high-voltage frequency converter is operated within the temperature range of permission.
