Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is current transformer heat-exchanger rig schematic diagram in the specific embodiment of the invention;
Wherein: 1-substrate, 2-cover plate, 3-water nozzle, 4-flat-plate heat pipe, 5-fin, 6-heater members.
Embodiment
The invention provides a kind of current transformer heat-exchanger rig, by installing flat-plate heat pipe and corresponding water-cooled pipeline, realizing heat and exchanging lost fast, effectively reduce temperature or power electronic device junction temperature in converter cabinet.
Fig. 1 is heat-exchanger rig schematic diagram in the specific embodiment of the invention, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As Fig. 1, the heat-exchanger rig in the specific embodiment of the invention comprises substrate 1, be arranged on the flat-plate heat pipe 4 of substrate 1 side and be arranged on the cover plate 2 of substrate 1 opposite side; Its cover plate 2 and substrate 1 for being tightly connected and forming the cooling liquid flowing channel of flowing cooling fluid in inside, cooling liquid flowing channel and circulation with driving water pump is connected, under the effect of driving water pump power, liquid circulation flows; There is the vacuum chamber of capillary structure in flat-plate heat pipe 4 and be positioned at the heat-exchange working medium of vacuum chamber.Be arranged on by this heat-exchanger rig after in current transformer screen cabinet, cover plate 2 can be fitted the heater members 6 in current transformer, realizes corresponding heat exchange.
Concrete, according to the difference of surrounding environment, in heat-exchanger rig use procedure, it may have three kinds of mode of operations:
As flat-plate heat pipe 4 ambient air be partial heat that the power electronic device such as hot-air, namely heater members 6 produces be discharged in air make air also become thermal source time (being called for short two heat source models), in flat-plate heat pipe 4, close hot-air one end is bringing-up section and close substrate 1 one end is condensation segment, heat-exchange working medium, at bringing-up section carburation by evaporation and in differential pressure action current downflow to the condensation segment condensation near substrate 1, is absorbed by cooling fluid after heat being passed to substrate 1 and discharges; The heat that the heater members 6 simultaneously pressing close to cover plate 2 produces also is absorbed by cooling fluid discharges.When using in current transformer screen cabinet, heat-exchanger rig generally adopts two heat source models work, when namely in air, heat is guided in the cooling fluid in substrate 1 by flat-plate heat pipe 4, the water-filled radiator that now substrate 1, cover plate 2 form becomes one and flat-plate heat pipe 4 cycle heat exchange, correspondingly reduce the length of cooling fluid pipeline, also just decrease the possibility that cooling fluid is leaked, improve device dependability.
As flat-plate heat pipe 4 ambient air be cold air and coolant flow is not enough to discharge the heat that heater members 6 produces time (be called for short two low-temperature receiver pattern), flat-plate heat pipe 4 becomes bringing-up section and is condensation segment near one end of cold air near one end of substrate 1, heat is passed to cold air from substrate 1 at bringing-up section carburation by evaporation in condensation segment condensation by heat-exchange working medium equally, to be discharged by heat by cooling fluid and cold air simultaneously.
And flat-plate heat pipe 4 ambient air and substrate 1 environment temperature basically identical time, owing to not having temperature difference dynamic action, in flat-plate heat pipe 4, heat-exchange working medium does not flow and does not produce heat exchange effect, only absorbs heat side by side except heat by the cooling fluid in cooling passage.
For improving the heat exchange efficiency of whole heat-exchanger rig, multiple flat-plate heat pipe 4 in the embodiment of the invention, is adopted to be connected with substrate 1, and the fin 5 connected between flat-plate heat pipe 4; Radiating fin 5 can be utilized like this to increase the exchange rate with air, improve heat exchange efficiency.
In embodiment shown in the drawings, be all arranged on cover plate 2 for the water nozzle 3 being communicated with cooling passage and extraneous heat abstractor, drive water pump to be sent in cooling passage by the cryogenic liquid of lowering the temperature in external world circulation; Certainly also water nozzle 3 can be arranged on substrate 1 in other embodiments.
Further, also can arrange in an embodiment of the present invention and the blower fan driving air to circulate on flat-plate heat pipe 4 surface, utilize blower fan blow air circulate and increase the heat exchange efficiency of flat-plate heat pipe 4 further.In practical application, also can arrange and the controller driving water pump to be communicated with blower fan, utilize controller to control to drive water pump and blower fan whether to work, switch different exchanger type, now form a kind of new mode of operation that a kind of and aforementioned Three models is different:
Under this mode of operation, cooling fluid stops flowing and is passed to air by heat from substrate 1 by flat-plate heat pipe 4; This mode of operation is applicable to cooling passage and breaks down or need the situation of overhauling, and especially can improve the reliability of whole cooling system work, reduce the too high and probability that breaks down of current transformer Yin Wendu when using.
In embody rule of the present invention, above all parts is preferably welding connecting mode; Wherein substrate 1 and cover plate 2 are preferably soldering or friction stir welding connected mode, and water nozzle 3 is preferably argon arc welding with cover plate 2 or friction stir welding mode is connected, and can ensure the sealing reliability of cooling liquid flowing channel like this.In addition, owing to not needing between flat-plate heat pipe 4 and substrate 1 to be tightly connected, therefore the two can be and is welded to connect, and also can be bonding or interference fit connection.
Above the current transformer heat-exchanger rig in the embodiment of the present invention is described in detail.Apply specific case herein to set forth principle of the present invention and execution mode; the explanation of above embodiment just understands core concept of the present invention for helping; without departing from the principles of the present invention; also can carry out some improvement and modification to the present invention, these improve and modify and also fall within the scope of protection of the present invention.
